• Help trying/downloading ubuntu

  - by koolomwee

  I can't try ubuntu. Every time i put in my disk and press try, it shows the ubuntu sign with the dots under it than it shows a command screen basically blinking saying that it closed and canceled applications belonging to ubuntu... Than I tried to download it from the disk... same thing. Than, because I have windows, I tried to download it from the website and it worked. I rebooted my computer and went into the Ubuntu option just to find a blinking command screen again... How do I get ubuntu to work? What does happen (with the command screen) is that it shows commands that are blinking to fast for me to read the whole thing, and then it stops after like a minute or two of blinking. The only thing I do get to read is that Ubuntu commanded some applications to shut down. In the CD one it only has like 5 error messages, and when I reboot and select Ubuntu, there are over a hundred error messages. With the live-cd I have to shut down my computer to use it again. With the reboot and clicking ubuntu option it reboots by itself. I expect it to actually start up with no error messages. UPDATE I've been trying to start Ubuntu for the last couple of days, and I noticed on my last try that it said "SIGNAL 15 RECEIVED"... It also said that it's stopping Bluetooth and all other programs, and that its rebooting Maybe that'll help a little with answering my question... thanks :) this also might help: computer brand/model: HP Windows 7 Home Premium Service Pack 1, HPE240f graphics card: ATI Radeon HD 5570 I also wrote the same question here: https://answers.launchpad.net/wubi/+question/194537 might help a little more with information

• How to handle notifications to several partial views of the same model?

  - by Seki

  I am working on refactoring an old simulation of a Turing machine. The application uses a class that contains the state and the logic of program execution, and several panels to display the tape representation and show the state, messages, and the GUI controls (start, stop, program listing, ...). I would like to refactor it using the MVC architecture that was not used originaly: the Frame is the only way to get access to the different panels and there is also a strong coupling between the "engine" class and the GUI updates in the way of frame.displayPanel.state.setText("halted"); or frame.outputPanel.messages.append("some thing"); It looks to me that I should put the state related code into an observable model class and make the different panels observers. My problem is that the java Observable class only provides a global notification to the Observers, while I would prefer not to refresh every Observers everytime, but only when the part that specificaly observe has changed. I am thinking of implementing myself several vectors of listeners (for the state / position, for the output messages, ...) but I feel like reinventing the wheel. I though also about adding some flags that the observers could check like isNewMessageAvailable(), hasTapeMoved(), etc but it sounds also approximative design. BTW, is it ok to keep the fetch / execute loop into the model or should I move it in another place? We can think in a theorical ideal way as I am completely revamping this small application.

• Tips / techniques for high-performance C# server sockets

  - by McKenzieG1

  I have a .NET 2.0 server that seems to be running into scaling problems, probably due to poor design of the socket-handling code, and I am looking for guidance on how I might redesign it to improve performance. Usage scenario: 50 - 150 clients, high rate (up to 100s / second) of small messages (10s of bytes each) to / from each client. Client connections are long-lived - typically hours. (The server is part of a trading system. The client messages are aggregated into groups to send to an exchange over a smaller number of 'outbound' socket connections, and acknowledgment messages are sent back to the clients as each group is processed by the exchange.) OS is Windows Server 2003, hardware is 2 x 4-core X5355. Current client socket design: A TcpListener spawns a thread to read each client socket as clients connect. The threads block on Socket.Receive, parsing incoming messages and inserting them into a set of queues for processing by the core server logic. Acknowledgment messages are sent back out over the client sockets using async Socket.BeginSend calls from the threads that talk to the exchange side. Observed problems: As the client count has grown (now 60-70), we have started to see intermittent delays of up to 100s of milliseconds while sending and receiving data to/from the clients. (We log timestamps for each acknowledgment message, and we can see occasional long gaps in the timestamp sequence for bunches of acks from the same group that normally go out in a few ms total.) Overall system CPU usage is low (< 10%), there is plenty of free RAM, and the core logic and the outbound (exchange-facing) side are performing fine, so the problem seems to be isolated to the client-facing socket code. There is ample network bandwidth between the server and clients (gigabit LAN), and we have ruled out network or hardware-layer problems. Any suggestions or pointers to useful resources would be greatly appreciated. If anyone has any diagnostic or debugging tips for figuring out exactly what is going wrong, those would be great as well. Note: I have the MSDN Magazine article Winsock: Get Closer to the Wire with High-Performance Sockets in .NET, and I have glanced at the Kodart "XF.Server" component - it looks sketchy at best.

• ActiveMQ 5.2.0 + REST + HTTP POST = java.lang.OutOfMemoryError

  - by Bruce Loth

  First off, I am a newbie when it comes to JMS & ActiveMQ. I have been looking into a messaging solution to serve as middleware for a message producer that will insert XML messages into a queue via HTTP POST. The producer is an existing system written in C++ that cannot be modified (so Java and the C++ API are out). Using the "demo" examples and some trial and error, I have cobbled together a working example of what I want to do (on a windows box). The web.xml I configured in a test directory under "webapps" specifies that the HTTP POST messages received from the producer are to be handled by the MessageServlet. I added a line for the text app in "activemq.xml" ('ow' is the test app dir): I created a test script to "insert" messages into the queue which works well. The problem I am running into is that it as I continue to insert messages via REST/HTTP POST, the memory consumption and thread count used by ActiveMQ continues to rise (It happens when I have timely consumers as well as slow or non-existent consumers). When memory consumption gets around 250MB's and the thread count exceeds 5000 (as shown in windows task manager), ActiveMQ crashes and I see this in the log: Exception in thread "ActiveMQ Transport Initiator: vm://localhost#3564" java.lang.OutOfMemoryError: unable to create new native thread It is as if Jetty is spawning a new thread to handle each HTTP POST and the thread never dies. I did look at this page: http://activemq.apache.org/javalangoutofmemory.html and tried but that didn't fix the problem (although I didn't fully understand the implications of the change either). Does anyone have any ideas? Thanks! Bruce Loth PS - I included the "test message producer" python script below for what it is worth. I created batches of 100 messages and continued to run the script manually from the command line while watching the memory consumption and thread count of ActiveMQ in task manager. def foo(): import httplib, urllib body = "<?xml version='1.0' encoding='UTF-8'?>\n \ <ROOT>\n \ [snip: xml deleted to save space] </ROOT>" headers = {"content-type": "text/xml", "content-length": str(len(body))} conn = httplib.HTTPConnection("127.0.0.1:8161") conn.request("POST", "/ow/message/RDRCP_Inbox?type=queue", body, headers) response = conn.getresponse() print response.status, response.reason data = response.read() conn.close() ## end method definition ## Begin test code count = 0; while(count < 100): # Test with batches of 100 msgs count += 1 foo()

• jQuery Validation plugin: checkbox groups and error message issues

  - by boomturn

  I've put together a form using the jQuery Validation plugin, and all inputs are fine with working validation and error messages – except for checkboxes. I have two checkbox problems. The first is that the Validation plugin API doesn't seem to handle checkboxes in grouped contexts (I'm using fieldsets for grouping). Found several approaches to the issue here, including reference to a post by Rebecca Murphey for a more general case using a custom method and class. Adapting that to this situation: jQuery.validator.addMethod('required_group', function(val, el) { var fieldParent = $(el).closest('fieldset'); return fieldParent.find('.required_group:checked').length; }); jQuery.validator.addClassRules('required_group', { 'required_group': true }); jQuery.validator.messages.required_group = 'Please check at least one box.'; This sort of works, but produces error messages on every checkbox, and only removes them as each box is clicked. This is not an acceptable situation for the user, who can only get rid of them by clicking false positives. Ideally, I guess what's needed is something to prevent or eliminate extra messages before they are displayed and use errorPlacement to display a single error message in the parent fieldset, that would then be removed with a click on any checkbox. Less ideally, maybe they would all display but an event handler could turn off the full set of redundant messages with a click, which is what this approach offered by tvanfosson appears to do. (Another customized approach here, but I couldn't get it to work.) I guess I should also note this form requires the checkboxes to have different names. My second problem is that one of the fieldsets with checkboxes in the form also contains a nested fieldset of checkboxes under one of the outer checkboxes. So in addition to the first-level one-box-checked requirement, if the particular checkbox containing the second-level checkboxes is checked, then at least one of the second-level boxes must be checked. Not sure about the right approach; I'm guessing what needs to happen (following the above scheme) is that the trigger checkbox would use toggleClass to add/remove 'required_group' class to all the checkboxes in the subfield, which would then (hopefully) behave the same as the parent field: $("#triggerCheckbox").click(function () { $(this).find(":checkbox").toggleClass("required_group"); }); Any suggestions or ideas welcome. I'm well beyond my limited jQuery skills on this one and would be happy to hear that I missed simple, elegant and/or obvious ways to do this!

• What happens when several Java servlet apps running on the same port ?

  - by Frank

  Something strange happened to my servlets and I think I've figured out why, yet I'm more confused. I used Netbean6.7 to develop a Paypal IPN (Instant Payment Notification) message servlet, it listens on port 8080 by default for Paypal IPN messages. I used some sample Java code from it's web site, but when it ran, only about 1 in 10 messages came through, and they looked correct, but why 1 in 10 ? Not 100% or none ? So I asked some questions here and got some advices, one in particular points me to Google's App Engine, so I downloaded it and ran the demo guestbook while my IPN servlet is still running on Netbeans, the strange thing happened, after I entered "appengine-java-sdk-1.3.2\bin\dev_appserver.cmd appengine-java-sdk-1.3.2\demos\guestbook\war" from the command prompt, I went to the following url on my browser "http://localhost:8080/", I thought I would see the Google demo guestbook page, NO, what I saw was another servlet I developed 2 years ago : "Web Academy", online course registration app. How can that happen ? I never started it, and I haven't touch that project for years. I guess because it's also listening on port 8080, so now I understand why the IPN messages only came through 1 in 10 times, because another servlet was also listening on that port and could have got the messages intended for IPN, or some how those two servlets' processes mixed up and therefore couldn't respond to Paypal properly, and failed. In order to verify some of my guesses, I turn off Netbeans, and ran the Google guestbook again at the prompt, this time on my browser http://localhost:8080/ points to the demo guestbook page. My Urls look like this : [A] Paypal IPN : http://localhost:8080/PayPal_App/PayPal_Servlet [B] Web Academy : http://localhost:8080/ So now, my questions are : <1> Why the "Web Academy" servlet was auto started when I ran the Paypal servlet ? <2> If I change the IPN listening port to 8083, would that mean I can run both of them on my PC at the same time without affecting each other ? <3> But I still don't understand, [A] and [B] look different, if a page for [A] is refreshed, it should show the Paypal content, and another page looking at [B] should show the Web Academy content, and that's exactly what happens when I started Netbeans to run the Paypal servlet, both pages show their respective content correctly side by side without interfering with each other, how come the IPN messages couldn't get through 100% of the time ? <4> In Netbeans how to assign 8080 to servlet [A] and assign port 8083 to servlet [B] ? <5> How to turn off auto start of Web Academy by Netbeans ?

  If user enters his text in the text box and saves it and again what's to add some more text he can edit that text and save it if required. Firstly if user enters that text with some links I, detected them and converted any hyperlinks to linkify in new tab. Secondly if user wants to add some more text and links he clicks on edit and add them and save it at this time I must ignore the links that already hyperlinked with anchor button Please help and advice For example: what = "<span>In the task system, is there a way to automatically have any site / page URL or image URL be hyperlinked in a new window?</span><br><br><span>So If I type or copy http://www.stackoverflow.com/&nbsp; for example anywhere in the description, in any of the internal messages or messages to clients, it automatically is a hyperlink in a new window.</span><br><a href="http://www.stackoverflow.com/">http://www.stackoverflow.com/</a><br> <br><span>Or if I input an image URL anywhere in support description, internal messages or messages to cleints, it automatically is a hyperlink in a new window:</span><br> <span>https://static.doubleclick.net/viewad/4327673/1-728x90.jpg</span><br><br><a href="https://static.doubleclick.net/viewad/4327673/1-728x90.jpg">https://static.doubleclick.net/viewad/4327673/1-728x90.jpg</a><br><br><br><span>This would save us a lot time in task building, reviewing and creating messages.</span> Test URL's http://www.stackoverflow.com/ http://stackoverflow.com/ https://stackoverflow.com/ www.stackoverflow.com //stackoverflow.com/ <a href='http://stackoverflow.com/'>http://stackoverflow.com/</a>"; I've tried this code function Linkify(what) { str = what; out = ""; url = ""; i = 0; do { url = str.match(/((https?:\/\/)?([a-z\-]+\.)*[\-\w]+(\.[a-z]{2,4})+(\/[\w\_\-\?\=\&\.]*)*(?![a-z]))/i); if(url!=null) { // get href value href = url[0]; if(href.substr(0,7)!="http://") href = "http://"+href; // where the match occured where = str.indexOf(url[0]); // add it to the output out += str.substr(0,where); // link it out += '<a href="'+href+'" target="_blank">'+url[0]+'</a>'; // prepare str for next round str = str.substr((where+url[0].length)); } else { out += str; str = ""; } } while(str.length>0); return out; } Please help Thanks.

• Parsing string logic issue c#

  - by N0xus

  This is a follow on from this question My program is taking in a string that is comprised of two parts: a distance value and an id number respectively. I've split these up and stored them in local variables inside my program. All of the id numbers are stored in a dictionary and are used check the incoming distance value. Though I should note that each string that gets sent into my program from the device is passed along on a single string. The next time my program receives that a signal from a device, it overrides the previous data that was there before. Should the id key coming into my program match one inside my dictionary, then a variable held next to my dictionaries key, should be updated. However, when I run my program, I don't get 6 different values, I only get the same value and they all update at the same time. This is all the code I have written trying to do this: Dictionary<string, string> myDictonary = new Dictionary<string, string>(); string Value1 = ""; string Value2 = ""; string Value3 = ""; string Value4 = ""; string Value5 = ""; string Value6 = ""; void Start() { myDictonary.Add("11111111", Value1); myDictonary.Add("22222222", Value2); myDictonary.Add("33333333", Value3); myDictonary.Add("44444444", Value4); myDictonary.Add("55555555", Value5); myDictonary.Add("66666666", Value6); } private void AppendString(string message) { testMessage = message; string[] messages = message.Split(','); foreach(string w in messages) { if(!message.StartsWith(" ")) outputContent.text += w + "\n"; } messageCount = "RSSI number " + messages[0]; uuidString = "UUID number " + messages[1]; if(myDictonary.ContainsKey(messages[1])) { Value1 = messageCount; Value2 = messageCount; Value3 = messageCount; Value4 = messageCount; Value5 = messageCount; Value6 = messageCount; } } How can I get it so that when programs recives the first key, for example 1111111, it only updates Value1? The information that comes through can be dynamic, so I'd like to avoid harding as much information as I possibly can.

• I need to understand why my server turned off

  - by Dema

  Our organization was robbed and definitely it was inside job. I was set up. I work as a manager and as system administrator in this organization and everything goes against me. The only clue I have is that someone accidentally or intentionally turned of a server that is in the office indicating that some one was inside at the time that no one should be. This is the only evidence I have that can justify me.  I looked the log files and they show that the Power button was pressed. Can you help me to find out that that was not a bug or systems overheat? I will post the log files and if you will ask more I will gladly provide the information.

• BizTalk and IBM WebSphere MQ Errors

  - by Christopher House

  The project I'm currently working on is going to make heavy use of IBM WebShere MQ to send messages from BizTalk to the client's iSeries box.  I'd never previously worked with WebSphere MQ, so I didn't really have any idea what it would take to get this to work.  I was pleasantly surprised that it wasn't too difficult to configure a send port and pass messages through it to a queue.  Or so I thought... A couple of weeks ago, the client gave me the name of a host, queue manager and queue that I'd been using for my development.  Everything was going great, I was able to put messages onto the queue, I was happy, the client was happy.  Life was good.  Then the client tells me that the host I've been connecting to is actually a Solaris box and that in prod, we'll actually be sending to an iSeries.  We both agree that it would behoove us to start pointing my dev environment to their dev iSeries box in order to flush out any weirdness there might be.  As it turns out, it was a good thing we made the change.  As soon as I reconfigured my BRE policy that sets endpoint information to point to the iSeries queue, we started seeing failures in the event log.  An example from the event log: Event Type: Error Event Source: BizTalk Server 2009 Event Category: BizTalk Server 2009 Event ID: 5754 Date:  6/9/2010 Time:  10:16:41 AM User:  N/A Computer: WINDOWS2003 Description: A message sent to adapter "MQSC" on send port "<my dynamic sendport name>" with URI "mqsc://client/tcp/<hostname>(1414)/<queue manager name>/<queue name>" is suspended.  Error details: Failure encountered while attempting to open queue. queue = <queue name> queueManager = <queue manager name>, reasonCode = 6124  MessageId:  {76825C7C-611A-4A56-8A6F-35E1124BDB5C}  InstanceID: {BA389103-DF9B-493F-8C61-44574822AAD6} The key piece of information in the event entry is the reasonCode, 6124.  A quick Google search shows that reasonCode 6124 is the code for MQRC_NOT_CONNECTED.  According to IBM's docs, this means that you've tried to send a message without first opening a connection to the queue manager.  Obviously, in the context of BizTalk, this is an unexpected error, since this sort of thing should be managed entirely by the send adapter. Perusing IBM's documentation a bit more, I came across some info on how to turn on tracing for MQ.  With tracing enabled, I tried sending a message again, then went and reviewed the trace files.  The bulk of the information in the trace files didn't mean a thing to me, but at the end of one of the files, I did notice this: 00006257 15:40:20.327795   3500.4      RSESS:000009 ------{  reqReleaseConn 00006258 15:40:20.328714   3500.4      RSESS:000009 ------}  reqReleaseConn (rc=OK) 00006259 15:40:20.328727   3500.4      RSESS:000009 ------{  xcsClearTraceIdent 0000625A 15:40:20.328739   3500.4           :       ------}  xcsClearTraceIdent (rc=OK) 0000625B 15:40:20.328752   3500.4           :       -----}! trmzstMQCONNX (rc=MQRC_NOT_AUTHORIZED) 0000625C 15:40:20.328765   3500.4           :       ----}!

ImqQueue::unlock (rc=Unknown(1)) It seemed like the MQRC_NOT_CONNECTED error was being caused by a security related issue (MQRC_NOT_AUTHORIZED).  I did notice something earlier in the log where it appeared that MQ was passing a field named UID with a value equal to the account name that my BizTalk service was running under.  I ended up creating a new local account on the BizTalk server that had the same name as a user which had access to the queue manager on the iSeries.  I then created a new host instance that ran under this new account, created a send handler for the MQSC adapter on this new host instance and reconfigured my orchestration to run on the new host instance.  After bouncing all my host instances, I was now able to send messages to the iSeries. It's still not clear to me why we were able to connect to the Solaris server.  I ended up contacting IBM's support and they did confirm that the process sending to MQ does in fact pass the identity to the queue manager it's connecting to.

• Creating typed WSDL’s for generic WCF services of the ESB Toolkit

  - by charlie.mott

  source: http://geekswithblogs.net/charliemott Question How do you make it easy for client systems to consume the generic WCF services exposed by the ESB Toolkit using messages that conform to agreed schemas\contracts?  Usually the developer of a system consuming a web service adds a service reference using a WSDL. However, the WSDL’s for the generic services exposed by the ESB Toolkit do not make it easy to develop clients that conform to agreed schemas\contracts. Recommendation Take a copy of the generic WSDL’s and modify it to use the proper contracts. This is very easy.  It will work with the generic on ramps so long as the <part>?</part> wrapping is removed from the WCF adapter configuration in the BizTalk receive locations.  Attempting to create a WSDL where the input and output messages are sent/returned with a <part> wrapper is a nightmare.  I have not managed it.  Consequences I can only see the following consequences of removing the <part> wrapper: ESB Test Client – I needed to modify the out-of-the-box ESB Test Client source code to make it send non-wrapped messages.  Flat file formatted messages – the endpoint will no longer support flat file message formats.  However, even if you needed to support this integration pattern through WCF, you would most-likely want to create a separate receive location anyway with its’ own independently configured XML disassembler pipeline component. Instructions These steps show how to implement a request-response implementation of this. WCF Receive Locations In BizTalk, for the WCF receive location for the ESB on-ramp, set the adapter Message settings\bindings to “UseBodyPath”: Inbound BizTalk message body  = Body Outbound WCF message body = Body Create a WSDL’s for each supported integration use-case Save a copy of the WSDL for the WCF generic receive location above that you intend the client system to use. Give it a name that mirrors the interface agreement (e.g. Esb_SuppliersSearchCommand_wsHttpBinding.wsdl).   Add any xsd schemas files imported below to this same folder.   Edit the WSDL to import schemas For example, this: <xsd:schema targetNamespace=http://microsoft.practices.esb/Imports /> … would become something like: <xsd:schema targetNamespace="http://microsoft.practices.esb/Imports">     <xsd:import schemaLocation="SupplierSearchCommand_V1.xsd"                            namespace="http://schemas.acme.co.uk/suppliersearchcommand/1.0"/>     <xsd:import  schemaLocation="SuppliersDocument_V1.xsd"                              namespace="http://schemas.acme.co.uk/suppliersdocument/1.0"/>     <xsd:import schemaLocation="Types\Supplier_V1.xsd"                              namespace="http://schemas.acme.co.uk/types/supplier/1.0"/>     <xsd:import  schemaLocation="GovTalk\bs7666-v2-0.xsd"                               namespace="http://www.govtalk.gov.uk/people/bs7666"/>     <xsd:import  schemaLocation="GovTalk\CommonSimpleTypes-v1-3.xsd"                             namespace="http://www.govtalk.gov.uk/core"/>     <xsd:import  schemaLocation="GovTalk\AddressTypes-v2-0.xsd"                              namespace="http://www.govtalk.gov.uk/people/AddressAndPersonalDetails"/> </xsd:schema> Modify the Input and Output message For example, this: <wsdl:message name="ProcessRequestResponse_SubmitRequestResponse_InputMessage">   <wsdl:part name="part" type="xsd:anyType"/> </wsdl:message> <wsdl:message name="ProcessRequestResponse_SubmitRequestResponse_OutputMessage">   <wsdl:part name="part" type="xsd:anyType"/> </wsdl:message> … would become something like: <wsdl:message name="ProcessRequestResponse_SubmitRequestResponse_InputMessage">   <wsdl:part name="part"                       element="ssc:SupplierSearchEvent"                         xmlns:ssc="http://schemas.acme.co.uk/suppliersearchcommand/1.0" /> </wsdl:message> <wsdl:message name="ProcessRequestResponse_SubmitRequestResponse_OutputMessage">   <wsdl:part name="part"                       element="sd:SuppliersDocument"                       xmlns:sd="http://schemas.acme.co.uk/suppliersdocument/1.0"/> </wsdl:message> This WSDL can now be added as a service reference in client solutions.

• SAB BizTalk Archiving Pipeline Component - Codeplex

  - by Stuart Brierley

  In an effort to give a little more to the BizTalk development community, I have created my first Codeplex project. The SAB BizTalk Archiving Pipeline Component was written using Visual Studio 2010 with BizTalk Server 2010 intended as the target platform.  It is currently at version 0.1, meaning that I have not yet completed all the intended functionality and have so far carried out a limited number of tests.  It does however archive files within the bounds of the functionailty so far implemented and seems to be stable in use. It is based on a recent evolution of a basic archiving component that I wrote in the past, and it is my hope that it will continue to evolve in the coming months. This work was inspired by some old posts by Gilles Zunino and Jeff Lynch.   You can download the documentation, source code or component dll from Codeplex, but to give you a taste here is the first section of the documentation to whet your appetite: SAB BizTalk Archiving Pipeline Component   The SAB BizTalk Archiving Pipeline Component has been developed to allow custom piplelines to be created that can archive messages at any stage of pipeline processing.   It works in both receive and send pipelines and will archive messages to file based on the configuration applied to the component in the BizTalk Administration Console.   The Archiving Pipeline Component has been coded for use with BizTalk Server 2010. Use with other versions of BizTalk has not been tested.   The Archiving Pipeline component is supplied as a dll file that should be placed in the BizTalk Server Pipeline Components folder. It can then be used when developing custom pipelines to be deployed as a part of your BizTalk Server applications.   This version of the component allows you to use a number of generic messaging macros and also a small number that are specific to the FILE adapter. It is intended to extend these macros to cover context properties from other adapters in future releases.     Archive Pipeline Parameters As with all pipeline components, the following parameters can be set when creating your custom pipeline and at runtime via the administration console.   Enabled:              Enables and disables the archive process.                                 True; messages will be archived.   False; messages will be passed to the next stage in the pipeline without performing any processing.   File Name:          The file name of the archived message.   Allows the component to build the archive filename at run-time; based on the values entered, the permitted macros and data extracted from the message context properties.   e.g.        %FileReceivedFileName%-%InterchangeSequenceNumber%   File Mask:           The extension to be added to the File Name following all Macro processing.   e.g.        .xml   File Path:             The path on which the archived message should be saved.   Allows the component to build the archive directory at run-time; based on the values entered, permitted macros and data extracted from the message context properties.   e.g.        C:\Archive\%ReceivePortName%\%Year%\%Month%\%Day%\                   \\ArchiveShare\%ReceivePortName%\%Date%\     Overwrite:          Enables and disables existing file overwrites.   True; any existing file with the same File Path/Name combination (following macro replacement) will be overwritten.   False; any existing file with the same File Path/Name combination (following macro replacement) will not be overwritten.  The current message will be archived with a GUID appended to the File Name.

• NetBeans Java Hints: Quick & Dirty Guide

  - by Geertjan

  In NetBeans IDE 7.2, a new wizard will be found in the "Module Development" category in the New File dialog, for creating new Java Hints. Select a package in a NetBeans module project. Right click, choose New/Other.../Module Development/Java Hint: You'll then see this: Fill in: Class Name: the name of the class that should be generated. E.g. "Example". Hint Display Name: the display name of the hint itself (as will appear in Tools/Options). E.g. "Example Hint". Warning Message: the warning that should be produced by the hint. E.g. "Something wrong is going on". Hint Description: a longer description of the hint, will appear in Tools/Options and eventually some other places. E.g. "This is an example hint that warns about an example problem." Will also provide an Automatic Fix: whether the hint will provide some kind of transformation. E.g. "yes". Fix Display Name: the display name of such a fix/transformation. E.g. "Fix the problem". Click Finish. Should generate "Example.java", the hint itself: import com.sun.source.util.TreePath; import org.netbeans.api.java.source.CompilationInfo; import org.netbeans.spi.editor.hints.ErrorDescription; import org.netbeans.spi.editor.hints.Fix; import org.netbeans.spi.java.hints.ConstraintVariableType; import org.netbeans.spi.java.hints.ErrorDescriptionFactory; import org.netbeans.spi.java.hints.Hint; import org.netbeans.spi.java.hints.HintContext; import org.netbeans.spi.java.hints.JavaFix; import org.netbeans.spi.java.hints.TriggerPattern; import org.openide.util.NbBundle.Messages; @Hint(displayName = "DN_com.bla.Example", description = "DESC_com.bla.Example", category = "general") //NOI18N @Messages({"DN_com.bla.Example=Example Hint", "DESC_com.bla.Example=This is an example hint that warns about an example problem."}) public class Example { @TriggerPattern(value = "$str.equals(\"\")", //Specify a pattern as needed constraints = @ConstraintVariableType(variable = "$str", type = "java.lang.String")) @Messages("ERR_com.bla.Example=Something wrong is going on") public static ErrorDescription computeWarning(HintContext ctx) { Fix fix = new FixImpl(ctx.getInfo(), ctx.getPath()).toEditorFix(); return ErrorDescriptionFactory.forName(ctx, ctx.getPath(), Bundle.ERR_com.bla_Example(), fix); } private static final class FixImpl extends JavaFix { public FixImpl(CompilationInfo info, TreePath tp) { super(info, tp); } @Override @Messages("FIX_com.bla.Example=Fix the problem") protected String getText() { return Bundle.FIX_com_bla_Example(); } @Override protected void performRewrite(TransformationContext ctx) { //perform the required transformation } } } Should also generate "ExampleTest.java", a test for it. Unfortunately, the wizard infrastructure is not capable of handling changes related to test dependencies. So the ExampleTest.java has a todo list at its begining: /* TODO to make this test work:  - add test dependency on Java Hints Test API (and JUnit 4)  - to ensure that the newest Java language features supported by the IDE are available,   regardless of which JDK you build the module with:  -- for Ant-based modules, add "requires.nb.javac=true" into nbproject/project.properties  -- for Maven-based modules, use dependency:copy in validate phase to create   target/endorsed/org-netbeans-libs-javacapi-*.jar and add to endorseddirs   in maven-compiler-plugin configuration  */Warning: if this is a project for which tests never existed before, you may need to close&reopen the project, so that "Unit Test Libraries" node appears - a bug in apisupport projects, as far as I can tell.  Thanks to Jan Lahoda for the above rough guide.

• AWS .NET SDK v2: setting up queues and topics

  - by Elton Stoneman

  Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/10/13/aws-.net-sdk-v2-setting-up-queues-and-topics.aspxFollowing on from my last post, reading from SQS queues with the new SDK is easy stuff, but linking a Simple Notification Service topic to an SQS queue is a bit more involved. The AWS model for topics and subscriptions is a bit more advanced than in Azure Service Bus. SNS lets you have subscribers on multiple different channels, so you can send a message which gets relayed to email address, mobile apps and SQS queues all in one go. As the topic owner, when you request a subscription on any channel, the owner needs to confirm they’re happy for you to send them messages. With email subscriptions, the user gets a confirmation request from Amazon which they need to reply to before they start getting messages. With SQS, you need to grant the topic permission to write to the queue. If you own both the topic and the queue, you can do it all in code with the .NET SDK. Let’s say you want to create a new topic, a new queue as a topic subscriber, and link the two together. Creating the topic is easy with the SNS client (which has an expanded name, AmazonSimpleNotificationServiceClient, compare to the SQS class which is just called QueueClient): var request = new CreateTopicRequest(); request.Name = TopicName; var response = _snsClient.CreateTopic(request); TopicArn = response.TopicArn; In the response from AWS (which I’m assuming is successful), you get an ARN – Amazon Resource Name – which is the unique identifier for the topic. We create the queue using the same code from my last post, AWS .NET SDK v2: the message-pump pattern, and then we need to subscribe the queue to the topic. The topic creates the subscription request: var response = _snsClient.Subscribe(new SubscribeRequest { TopicArn = TopicArn, Protocol = "sqs", Endpoint = _queueClient.QueueArn }); That response will give you an ARN for the subscription, which you’ll need if you want to set attributes like RawMessageDelivery. Then the SQS client needs to confirm the subscription by allowing the topic to send messages to it. The SDK doesn’t give you a nice mechanism for doing that, so I’ve extended my AWS wrapper with a method that encapsulates it: internal void AllowSnsToSendMessages(TopicClient topicClient) { var policy = Policies.AllowSendFormat.Replace("%QueueArn%", QueueArn).Replace("%TopicArn%", topicClient.TopicArn); var request = new SetQueueAttributesRequest(); request.Attributes.Add("Policy", policy); request.QueueUrl = QueueUrl; var response = _sqsClient.SetQueueAttributes(request); } That builds up a policy statement, which gets added to the queue as an attribute, and specifies that the topic is allowed to send messages to the queue. The statement itself is a JSON block which contains the ARN of the queue, the ARN of the topic, and an Allow effect for the sqs:SendMessage action: public const string AllowSendFormat= @"{ ""Statement"": [ { ""Sid"": ""MySQSPolicy001"", ""Effect"": ""Allow"", ""Principal"": { ""AWS"": ""*"" }, ""Action"": ""sqs:SendMessage"", ""Resource"": ""%QueueArn%"", ""Condition"": { ""ArnEquals"": { ""aws:SourceArn"": ""%TopicArn%"" } } } ] }"; There’s a new gist with an updated QueueClient and a new TopicClient here: Wrappers for the SQS and SNS clients in the AWS SDK for .NET v2. Both clients have an Ensure() method which creates the resource, so if you want to create a topic and a subscription you can use:  var topicClient = new TopicClient(“BigNews”, “ImListening”); And the topic client has a Subscribe() method, which calls into the message pump on the queue client: topicClient.Subscribe(x=>Log.Debug(x.Body)); var message = {}; //etc. topicClient.Publish(message); So you can isolate all the fiddly bits and use SQS and SNS with a similar interface to the Azure SDK.

• Why does my Messaging Menu code not work when split into functions?

  - by fluteflute

  Below are two python programs. They're exactly the same, except for one is split into two functions. However only the one that's split into two functions doesn't work - the second function doesn't work. Why would this be? Note the code is taken from this useful blog post. Without functions (works): import gtk def show_window_function(x, y): print x print y # get the indicate module, which does all the work import indicate # Create a server item mm = indicate.indicate_server_ref_default() # If someone clicks your server item in the MM, fire the server-display signal mm.connect("server-display", show_window_function) # Set the type of messages that your item uses. It's not at all clear which types # you're allowed to use, here. mm.set_type("message.im") # You must specify a .desktop file: this is where the MM gets the name of your # app from. mm.set_desktop_file("/usr/share/applications/nautilus.desktop") # Show the item in the MM. mm.show() # Create a source item mm_source = indicate.Indicator() # Again, it's not clear which subtypes you are allowed to use here. mm_source.set_property("subtype", "im") # "Sender" is the text that appears in the source item in the MM mm_source.set_property("sender", "Unread") # If someone clicks this source item in the MM, fire the user-display signal mm_source.connect("user-display", show_window_function) # Light up the messaging menu so that people know something has changed mm_source.set_property("draw-attention", "true") # Set the count of messages in this source. mm_source.set_property("count", "15") # If you prefer, you can set the time of the last message from this source, # rather than the count. (You can't set both.) This means that instead of a # message count, the MM will show "2m" or similar for the time since this # message arrived. # mm_source.set_property_time("time", time.time()) mm_source.show() gtk.mainloop() With functions (second function is executed but doesn't actually work): import gtk def show_window_function(x, y): print x print y # get the indicate module, which does all the work import indicate def function1(): # Create a server item mm = indicate.indicate_server_ref_default() # If someone clicks your server item in the MM, fire the server-display signal mm.connect("server-display", show_window_function) # Set the type of messages that your item uses.

• Parsing nested JSON objects with JSON Framework for Objective-C

  - by Sheehan Alam

  I have the following JSON object: { "response": { "status": 200 }, "messages": [ { "message": { "user": "value" "pass": "value", "url": "value" } ] } } I am using JSON-Framework (also tried JSON Touch) to parse through this and create a dictionary. I want to access the "message" block and pull out the "user", "pass" and "url" values. In Obj-C I have the following code: // Create new SBJSON parser object SBJSON *parser = [[SBJSON alloc] init]; // Prepare URL request to download statuses from Twitter NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:myURL]]; // Perform request and get JSON back as a NSData object NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; // Get JSON as a NSString from NSData response NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]; //Print contents of json-string NSArray *statuses = [parser objectWithString:json_string error:nil]; NSLog(@"Array Contents: %@", [statuses valueForKey:@"messages"]); NSLog(@"Array Count: %d", [statuses count]); NSDictionary *results = [json_string JSONValue]; NSArray *tweets = [[results objectForKey:@"messages"] objectForKey:@"message"]; for (NSDictionary *tweet in tweets) { NSString *url = [tweet objectForKey:@"url"]; NSLog(@"url is: %@",url); } I can pull out "messages" and see all of the "message" blocks, but I am unable to parse deeper and pull out the "user", "pass", and "url".

• HL7 parsing in PHP

  - by Narcissus

  Hi all, I'm looking into options for parsing HL7 messages via PHP. I'm aware of the Net_HL7 package on PEAR but to be perfectly honest, I don't think that I want to base my code around a seemingly 'abandoned' package and even if I did, I just don't think that my brain suits the functions 'correctly'. Maybe if I had more of an HL7 background it would make a bit more sense, I don't know. Anyway: I'm guessing that 95% of the time, I'm going to be parsing and reading data from messages. The other 5%, I'll be creating and/or sending messages. I don't necessarily need to do any form of validation on the messages themselves, I just need to pull/push data. I definitely need support for 'non-XML' HL7 v2.x, but naturally XML-based v2 and v3 would be a bonus. So does anyone have any suggestions as to other libraries that I might use? I'm looking for pure PHP solutions as I want to have minimal requirements on the server that aren't "copy this directory here". Thanks!

• WPF Memory Leak on XP (CMilChannel, HWND)

  - by vanja.

  My WPF application leaks memory at about 4kb/s. The memory usage in Task Manager climbs constantly until the application crashes with an "Out of Memory" exception. By doing my own research I have found that the problem is discussed here: http://stackoverflow.com/questions/801589/track-down-memory-leak-in-wpf and #8 here: http://blogs.msdn.com/jgoldb/archive/2008/02/04/finding-memory-leaks-in-wpf-based-applications.aspx The problem described is: This is a leak in WPF present in versions of the framework up to and including .NET 3.5 SP1. This occurs because of the way WPF selects which HWND to use to send messages from the render thread to the UI thread. This sample destroys the first HWND created and starts an animation in a new Window. This causes messages sent from the render thread to pile up without being processed, effectively leaking memory. The solution offered is: The workaround is to create a new HwndSource first thing in your App class constructor. This MUST be created before any other HWND is created by WPF. Simply by creating this HwndSource, WPF will use this to send messages from the render thread to the UI thread. This assures all messages will be processed, and that none will leak. But I don't understand the solution! I have a subclass of Application that I am using and I have tried creating a window in that constructor but that has not solved the problem. Following the instructions given literally, it looks like I just need to add this to my Application constructor: new HwndSource(new HwndSourceParameters("MyApplication"));

• MINA: Performing synchronous write requests / read responses

  - by Matt Huggins

  I'm attempting to perform a synchronous write/read in a demux-based client application with MINA 2.0 RC1, but it seems to get stuck. Here is my code: public boolean login(final String username, final String password) { // block inbound messages session.getConfig().setUseReadOperation(true); // send the login request final LoginRequest loginRequest = new LoginRequest(username, password); final WriteFuture writeFuture = session.write(loginRequest); writeFuture.awaitUninterruptibly(); if (writeFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // retrieve the login response final ReadFuture readFuture = session.read(); readFuture.awaitUninterruptibly(); if (readFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // stop blocking inbound messages session.getConfig().setUseReadOperation(false); // determine if the login info provided was valid final LoginResponse loginResponse = (LoginResponse)readFuture.getMessage(); return loginResponse.getSuccess(); } I can see on the server side that the LoginRequest object is retrieved, and a LoginResponse message is sent. On the client side, the DemuxingProtocolCodecFactory receives the response, but after throwing in some logging, I can see that the client gets stuck on the call to readFuture.awaitUninterruptibly(). I can't for the life of me figure out why it is stuck here based upon my own code. I properly set the read operation to true on the session config, meaning that messages should be blocked. However, it seems as if the message no longer exists by time I try to read response messages synchronously. Any clues as to why this won't work for me?

• How does XMPP work with perl?

  - by TheGNUGuy

  Hey everybody, I am trying to make my own jabber bot but i have run into a little trouble. I have gotten my bot to respond to messages, however, if I try to change the bot's presence then it seems as though all of the messages you send to the bot get delayed. What I mean is when I run the script I change the presence so I can see that it is online. Then When I send it a message it takes 3 before the callback subroutine i have set up for messages gets called. After the 3rd message is sent and the chat subroutine is called it still process the first message I sent. This really doesn't pose TOO much of a problem except that I have it set up to log out when I send the message "logout" and it has to be followed by two more messages in order to log out. I am not sure what it is that I have to do to fix this but i think it has something to do with iq packets because I have an iq callback set as well and it gets called 2 times after setting the presence. Here is my source code: http://pastebin.com/MgKMhTML Thanks for your help!

• how to fix gateway timeout error in php???

  - by developer

  Iam having a php file that sends text messages on mobile to all the users that i have in my database's particular table. Now the entries are like 2000 or so in number and this number will keep on increasing. On my page there is a small form that selects a list of the users to whom message is to be sent from a drop down and then user writes the text to be sent in a textarea and then on clicking the submit button php script stars sending the messages to mobile numbers. Now while trying to send messages my browser has shown gateway timeout error but the script kept on running and messages are sent to the mobiles but not once but 6 times. I checked my script my query and all the code is correct.This all happened coz of that gateway timeout. Now does this gateway timeout kepts the script running again and again till the browser is not closed?? is this was the reason that a single message was sent 6 times to mobile numbers?? I mean how can i escape my file from getting this gateway error so that one message is sent only one time to a number??

• Including variables inside curly braces in a Zend config ini file on Linux

  - by Dave Morris

  I am trying to include a variable in a .ini file setting by surrounding it with curly braces, and Zend is complaining that it cannot parse it properly on Linux. It works properly on Windows, though: welcome_message = Welcome, {0}. This is the error that is being thrown on Linux: : Uncaught exception 'Zend_Config_Exception' with message 'Error parsing /var/www/html/portal/application/configs/language/messages.ini on line 10 ' in /usr/local/zend/share/ZendFramework/library/Zend/Config/Ini.php:181 Stack trace: 0 /usr/local/zend/share/ZendFramework/library/Zend/Config/Ini.php(201): Zend_Config_Ini-&gt;_parseIniFile('/var/www/html/p...') 1 /usr/local/zend/share/ZendFramework/library/Zend/Config/Ini.php(125): Zend_Config_Ini-&gt;_loadIniFile('/var/www/html/p...') 2 /var/www/html/portal/library/Ingrain/Language/Base.php(49): Zend_Config_Ini-&gt;__construct('/var/www/html/p...', NULL) 3 /var/www/html/portal/library/Ingrain/Language/Base.php(23): Ingrain_Language_Base-&gt;setConfig('messages.ini', NULL, NULL) 4 /var/www/html/portal/library/Ingrain/Language/Messages.php(7): Ingrain_Language_Base-&gt;__construct('messages.ini', NULL, NULL, NULL) 5 /var/www/html/portal/library/Ingrain/Helper/Language.php(38): Ingrain_Language_Messages-&gt;__construct() 6 /usr/local/zend/share/ZendFramework/library/Zend/Contr in We are able to get the error to go away on Linux if we surround the braces with quotes, but that seems like a strange solution: welcome_message = Welcome, "{"0"}". Is there a better way to solve this issue for all platforms? Thanks for your help, Dave

• How do the XMPP modules work in perl?

  - by TheGNUGuy

  Hey everybody, I am trying to make my own jabber bot but i have run into a little trouble. I have gotten my bot to respond to messages, however, if I try to change the bot's presence then it seems as though all of the messages you send to the bot get delayed. What I mean is when I run the script I change the presence so I can see that it is online. Then When I send it a message it takes 3 before the callback subroutine i have set up for messages gets called. After the 3rd message is sent and the chat subroutine is called it still process the first message I sent. This really doesn't pose TOO much of a problem except that I have it set up to log out when I send the message "logout" and it has to be followed by two more messages in order to log out. I am not sure what it is that I have to do to fix this but i think it has something to do with iq packets because I have an iq callback set as well and it gets called 2 times after setting the presence. Here is my source code: http://pastebin.com/MgKMhTML Thanks for your help!

• SendMessage to window created by AllocateHWND cause deadlock

  - by user2704265

  In my Delphi project, I derive a thread class TMyThread, and follow the advice from forums to use AllocateHWnd to create a window handle. In TMyThread object, I call SendMessage to send message to the window handle. When the messages sent are in small volume, then the application works well. However, when the messages are in large volume, the application will deadlock and lose responses. I think may be the message queue is full as in LogWndProc, there are only codes to process the message, but no codes to remove the messages from the queue, that may cause all the processed messages still exist in the queue and the queue becomes full. Is that correct? The codes are attached below: var hLogWnd: HWND = 0; procedure TForm1.FormCreate(Sender: TObject); begin hLogWnd := AllocateHWnd(LogWndProc); end; procedure TForm1.FormDestroy(Sender: TObject); begin if hLogWnd <> 0 then DeallocateHWnd(hLogWnd); end; procedure TForm1.LogWndProc(var Message: TMessage); var S: PString; begin if Message.Msg = WM_UPDATEDATA then begin S := PString(msg.LParam); try List1.Items.Add(S^); finally Dispose(S); end; end else Message.Result := DefWindowProc(hLogWnd, Message.Msg, Message.WParam, Message.LParam); end; procedure TMyThread.SendLog(I: Integer); var Log: PString; begin New(Log); Log^ := 'Log: current stag is ' + IntToStr(I); SendMessage(hLogWnd, WM_UPDATEDATA, 0, LPARAM(Log)); Dispose(Log); end;
