• Subversion versus Vault

  - by WebDude

  I'm currently reviewing the benefits of moving from SVN to a SourceGear Vault. Has anyone got advice or a link to a detailed comparison between the two? Bear in mind I would have to move my current Source Control system across which works strongly in SVN's favor Here is some info I have found out thus far from my own investigations. I have been taking some time tests between the two and vault seems to perform most operations much faster. Time tests used the same server as the repository, the same workstation client, and the same project. Time Comparisons SVN Add/Commit    12:30 Get Latest Revision    5:35 Tagging/Labelling    0:01 Branching    N/A - I don't think true branching exists in SVN Vault Add/Commit    4:45 Get Latest Revision    0:51 Tagging/Labelling    0:30 Branching    3:23 (can't get this to format correctly) I also found an online source comparing some other points. This is the kind of information i'm looking for. Usage Comparisons Subversion is edit/merge/commit only. Vault allows you to do either edit/merge/commit or checkout/edit/checkin. Vault looks and acts just like VSS, which makes the learning curve effectively zero for VSS users. Vault has a VS plugin, but it only works if you're going to run in checkout-mode. Subversion has clients for pretty much every OS you can imagine; Vault has a GUI client for Windows and a command line client for Mono. Both will support remote work, since both use HTTP as their transport (Subversion uses extended DAV, Vault uses SOAP). Subversion installation, especially w/ Apache, is more complex. Subversion has a lot of third party support. Vault has just a few things. My question Has anyone got advice or a link to a detailed comparison between the two?

• php mailer char-coding problem

  - by Holian

  Hello! I try to use Phpmailer to send registration, activation..etc mail to users... require("class.phpmailer.php"); $mail -> charSet = "UTF-8"; $mail = new PHPMailer(); $mail->IsSMTP(); $mail->Host = "smtp.mydomain.org"; $mail->From = "[email protected]"; $mail->SMTPAuth = true; $mail->Username ="username"; $mail->Password="passw"; //$mail->FromName = $header; $mail->FromName = mb_convert_encoding($header, "UTF-8", "auto"); $mail->AddAddress($emladd); $mail->AddAddress("[email protected]"); $mail->AddBCC('[email protected]', 'firstadd'); $mail->Subject = $sub; $mail->Body = $message; $mail->WordWrap = 50; if(!$mail->Send()) { echo 'Message was not sent.'; echo 'Mailer error: ' . $mail->ErrorInfo; } The $message is contain latin characters. Unfortunatelly all webmail (gmail, webmail.mydomain.org, emailaddress.domain.xx) use different coding. How can i force to use UTF-8 coding to show my mail exactly same on all mailbox? I try to convert the mail header width mb_convert_encoding(), but with no luck. Thank you.

• TLS with SNI in Java clients

  - by ftrotter

  There is an ongoing discussion on the security and trust working group for NHIN Direct regarding the IP-to-domain mapping problem that is created with traditional SSL. If an HISP (as defined by NHIN Direct) wants to host thousands of NHIN Direct "Health Domains" for providers, then it will an "artificially inflated cost" to have to purchase an IP for each of those domains. Because Apache and OpenSSL have recently released TLS with support for the SNI extension, it is possible to use SNI as a solution to this problem on the server side. However, if we decide that we will allow server implementations of the NHINDirect transport layer to support TLS+SNI, then we must require that all clients support SNI too. OpenSSL based clients should do this by default and one could always us stunnel to implement an TLS+SNI aware client to proxy if your given programming language SSL implementation does not support SNI. It appears that native Java applications using OpenJDK do not yet support SNI, but I cannot get a straight answer out of that project. I know that there are OpenSSL Java libraries available but I have no idea if that would be considered viable. Can you give me a "state of the art" summary of where TLS+SNI support is for Java clients? I need a Java implementers perspective on this.

• Make user download pdf instead of saving to a location

  - by chupinette

  Hello!I was trying out the following code which actually saves the pdf file to C:/xampp/ I want to create a link so that when the user clicks on it. It prompts it to save the pdf file. <?php // create handle for new PDF document $pdf = pdf_new(); // open a file pdf_open_file($pdf, "try1.pdf"); // start a new page (A4) pdf_begin_page($pdf, 595, 842); pdf_set_parameter($pdf, 'FontOutline', 'Arial=c:\windows\fonts\arial.ttf'); // get and use a font object $font = pdf_findfont($pdf, "Arial", "host", 1); pdf_setfont($pdf, $font, 10); // print text pdf_show_xy($pdf, "There are more things in heaven and earth, Horatio,", 50, 750); pdf_show_xy($pdf, "than are dreamt of in your philosophy", 50, 730); // add an image under the text //$image = pdf_open_image_file($pdf, "jpeg", "shakespeare.jpg"); pdf_place_image($pdf, $image, 50, 650, 0.25); // end page pdf_end_page($pdf); // close and save file pdf_close($pdf); ?>

• forkpty - socket

  - by Alexxx

  Hi, I'm trying to develop a simple "telnet/server" daemon which have to run a program on a new socket connection. This part working fine. But I have to associate my new process to a pty, because this process have some terminal capabilities (like a readline). The code I've developped is (where socketfd is the new socket file descriptor for the new input connection) : int masterfd, pid; const char *prgName = "..."; char *arguments[10] = ....; if ((pid = forkpty(&masterfd, NULL, NULL, NULL)) < 0) perror("FORK"); else if (pid) return pid; else { close(STDOUT_FILENO); dup2(socketfd, STDOUT_FILENO); close(STDIN_FILENO); dup2(socketfd, STDIN_FILENO); close(STDERR_FILENO); dup2(socketfd, STDERR_FILENO); if (execvp(prgName, arguments) < 0) { perror("execvp"); exit(2); } } With that code, the stdin / stdout / stderr file descriptor of my "prgName" are associated to the socket (when looking with ls -la /proc/PID/fd), and so, the terminal capabilities of this process doesn't work. A test with a connection via ssh/sshd on the remote device, and executing "localy" (under the ssh connection) prgName, show that the stdin/stdout/stderr fd of this process "prgName" are associated to a pty (and so the terminal capabilities of this process are working fine). What I am doing wrong? How to associate my socketfd with the pty (created by forkpty) ? Thank Alex

• Uncatchable AccesViolationException

  - by Roy

  Hi all, I'm getting close to desperate.. I am developing a field service application for Windows Mobile 6.1 using C# and quite some p/Invoking. (I think I'm referencing about 50 native functions) On normal circumstances this goes without any problem, but when i start stressing the GC i'm getting a nasty 0xC0000005 error witch seems uncatchable. In my test i'm rapidly closing and opening a dialog form (the form did make use of native functions, but for testing i commented these out) and after a while the Windows Mobile error reporter comes around to tell me that there was an fatal error in my application. My code uses a try-catch around the Application.Run(masterForm); and hooks into the CurrentDomain.UnhandledException event, but the application still crashes. Even when i attach the debugger, visual studio just tells me "The remote connection to the device has been lost" when the exception occurs.. Since I didn't succeed to catch the exception in the managed environment, I tried to make sense out of the Error Reporter log file. But this doesn't make any sense, the only consistent this about the error is the application where it occurs in. The thread where the application occurs in is unknown to me, the module where the error occurs differs from time to time (I've seen my application.exe, WS2.dll, netcfagl3_5.dll and mscoree3_5.dll), even the error code is not always the same. (most of the time it's 0xC0000005, but i've also seen an 0X80000002 error, which is a warning accounting the first byte?) I tried debugging through bugtrap, but strangely enough this crashes with the same error code (0xC0000005). I tried to open the kdmp file with visual studio, but i can't seem to make any sense out of this because it only shows me disassembler code when i step into the error (unless i have the right .pbb files, which i don't). Same goes for WinDbg. To make a long story short: I frankly don't have a single clue where to look for this error, and I'm hoping some bright soul on stackoverflow does. I'm happy to provide some code but at this moment I don't know which piece to provide.. Any help is greatly appreciated!

• Detecting Xml namespace fast

  - by Anna Tjsoken

  Hello there, This may be a very trivial problem I'm trying to solve, but I'm sure there's a better way of doing it. So please go easy on me. I have a bunch of XSD files that are internal to our application, we have about 20-30 Xml files that implement datasets based off those XSDs. Some Xml files are small (<100Kb), others are about 3-4Mb with a few being over 10Mb. I need to find a way of working out what namespace these Xml files are in order to provide (something like) intellisense based off the XSD. The implementation of this is not an issue - another developer has written the code for this. But I'm not sure the best (and fastest!) way of detecting the namespace is without the use of XmlDocument (which does a full parse). I'm using C# 3.5 and the documents come through as a Stream (some are remote files). All the files are *.xml (I can detect if it was extension based) but unfortunately the Xml namespace is the only way. Right now I've tried XmlDocument but I've found it to be innefficient and slow as the larger documents are awaiting to be parsed (even the 100Kb docs). public string GetNamespaceForDocument(Stream document); Something like the above is my method signature - overloads include string for "content". Would a RegEx (compiled) pattern be good? How does Visual Studio manage this so efficiently? Another college has told me to find a fast Xml parser in C/C++, parse the content and have a stub that gives back the namespace as its slower in .NET, is this a good idea?

• SmtpClient.SendAsync - How to ensure my application doesn't finish before callback?

  - by James

  Hi, I need to send emails asychronously through a console application. I need to do some DB updates on the callback but my application is exiting before the callback code gets run! How can I stop this from happening in a nice manner rather than simply guessing how long to wait before exiting. I would imagine the Async calls get placed in some form of thread? Is it possible to check if any are waiting to be called? Sample Code private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e) { // Get the unique identifier for this asynchronous operation. String token = (string) e.UserState; if (e.Cancelled) { Console.WriteLine("[{0}] Send canceled.", token); } if (e.Error != null) { Console.WriteLine("[{0}] {1}", token, e.Error.ToString()); } else { // update DB Console.WriteLine("Message sent."); } } public static void Main(string[] args) { var users = Repository.GetUsers(); SmtpClient client = new SmtpClient("Host"); client.SendCompleted += new SendCompletedEventHandler(SendCompletedCallback); MailAddress from = new MailAddress("[email protected]", "System", Encoding.UTF8); foreach (var user in users) { MailAddress to = new MailAddress(user.Email); MailMessage message = new MailMessage(from, to); message.Body = "This is a test"; message.BodyEncoding = System.Text.Encoding.UTF8; message.Subject = "test message 1" + someArrows; message.SubjectEncoding = System.Text.Encoding.UTF8; string userState = String.Format("Message for user id {0}", user.ID); client.SendAsync(message, userState); message.Dispose(); } // need to wait here until I have received a callback for each message // otherwise the application will exit }

• SVN checkout browser

  - by phazei

  I've been looking all over for a SVN browser. Now I'm not talking about anything like WebSVN or TRAC, I don't want to browse the repository; I want to browse the checkout. I'm looking for a program that lets me browse the checkout (working copy) and shows me the info I'd normally need to SSH for. So I could mark specific files or folders for some commit button, or see the status, or view a diff between the working and a prev version. Basically a web GUI for a svn checkout. A [windows] program that can let you work on a remote checkout as if it were local would also work. Currently I have a checkout on my server running under dev.mysite.com. I log in via ftp and edit and upload the files. I also keep SSH open so I can do a svn st to see what files I've worked on and to commit changes. I want to work on the files on the same environment so I can't simply use a local checkout. But I don't want to need to work via SSH. Are there any apps such as I described? Like a repo browser but for checkouts to do commits. Like WebTortoiseSVN or such. Thanks

• How do I use a dependency on a Perl module installed in a non-standard location?

  - by Kinopiko

  I need to install two Perl modules on a web host. Let's call them A::B and X::Y. X::Y depends on A::B (needs A::B to run). Both of them use Module::Install. I have successfully installed A::B into a non-system location using perl Makefile.PL PREFIX=/non/system/location make; make test; make install Now I want to install X::Y, so I try the same thing perl Makefile.PL PREFIX=/non/system/location The output is $ perl Makefile.PL PREFIX=/non/system/location/ Cannot determine perl version info from lib/X/Y.pm *** Module::AutoInstall version 1.03 *** Checking for Perl dependencies... [Core Features] - Test::More ...loaded. (0.94) - ExtUtils::MakeMaker ...loaded. (6.54 >= 6.11) - File::ShareDir ...loaded. (1.00) - A::B ...missing. ==> Auto-install the 1 mandatory module(s) from CPAN? [y] It can't seem to find A::B in the system, although it is installed, and when it tries to auto-install the module from CPAN, it tries to write it into the system directory (ignoring PREFIX). I have tried using variables like PERL_LIB and LIB on the command line, after PREFIX=..., but nothing I have done seems to work. I can do make and make install successfully, but I can't do make test because of this problem. Any suggestions? I found some advice at http://servers.digitaldaze.com/extensions/perl/modules.html to use an environment variable PERL5LIB, but this also doesn't seem to work: export PERL5LIB=/non/system/location/lib/perl5/ didn't solve the problem.

• How to compile Python scripts for use in FORTRAN?

  - by Vincent Poirier

  Hello, Although I found many answers and discussions about this question, I am unable to find a solution particular to my situation. Here it is: I have a main program written in FORTRAN. I have been given a set of python scripts that are very useful. My goal is to access these python scripts from my main FORTRAN program. Currently, I simply call the scripts from FORTRAN as such: CALL SYSTEM ('python pyexample.py') Data is read from .dat files and written to .dat files. This is how the python scripts and the main FORTRAN program communicate to each other. I am currently running my code on my local machine. I have python installed with numpy, scipy, etc. My problem: The code needs to run on a remote server. For strictly FORTRAN code, I compile the code locally and send the executable to the server where it waits in a queue. However, the server does not have python installed. The server is being used as a number crunching station between universities and industry. Installing python along with the necessary modules on the server is not an option. This means that my “CALL SYSTEM ('python pyexample.py')” strategy no longer works. Solution?: I found some information on a couple of things in thread http://stackoverflow.com/questions/138521/is-it-feasible-to-compile-python-to-machine-code Shedskin, Psyco, Cython, Pypy, Cpython API These “modules”(? Not sure if that's what to call them) seem to compile python script to C code or C++. Apparently not all python features can be translated to C. As well, some of these appear to be experimental. Is it possible to compile my python scripts with my FORTRAN code? There exists f2py which converts FORTRAN code to python, but it doesn't work the other way around. Any help would be greatly appreciated. Thank you for your time. Vincent PS: I'm using python 2.6 on Ubuntu

• pylons on production server fedora 8

  - by stormdrain

  I'm interested in learning some python, and thought Pylons would be a good starting point (after spending 2 days trying to get django working -- to no avail). I have an Amazon EC2 instance with Fedora 8 on it. It is a bare-bones install. I am halfway through my second day of trying to get it to work. I have mod_wsgi installed. I have Apache (though that's a later task to tackle). I have easy_install, paster is working fine; basically all of the pre-requisites mentioned throughout the Pylons docs. I can't for the life of me get the thing to work. And I can't seem to find a coherent walkthough anywhere that lists all the steps necessary. There is tons of info out there, but it is all scattered. Wsgi this, python that. Google, google, google... "47 million results found for 'socket.error:(lol, 'Yous a goofs')". So, this is my latest attempt: apachectl -k stop cd /home/ paster create -t pylons test [blah blah.. ok] cd test nano development.ini [hmm, last time I changed the host from 127.0.0.1 to my domain name or url, it threw an error like socket.error: (99, 'Cannot assign requested address')... I'll just leave it] [open port 5000 on firewall] paster serve development.ini [firefox-url:5000] Firefox can't establish a connection to the server Doing these steps locally works as expected. This is just a test to see if I can get it to work at all, which I can't. If I get it to work, then is the task of getting it to work with apache. My madness is that I'd like to play around a little developing and deploying before diving into a full-fledged project. So far: self, I am dissapoint.

• HttpModule.Init - safely add HttpApplication.BeginRequest handler in IIS7 integrated mode

  - by Paul Smith

  My question is similar but not identical to: http://stackoverflow.com/questions/1123741/why-cant-my-host-softsyshosting-com-support-beginrequest-and-endrequest-event (I've also read the mvolo blog referenced therein) The goal is to successfully hook HttpApplication.BeginRequest in the IHttpModule.Init event (or anywhere internal to the module), using a normal HttpModule integrated via the system.webServer config, i.e. one that doesn't: invade Global.asax or override the HttpApplication (the module is intended to be self-contained & reusable, so e.g. I have a config like this): <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules> <remove name="TheHttpModule" /> <add name="TheHttpModule" type="Company.HttpModules.TheHttpModule" preCondition="managedHandler" /> So far, any strategy I've tried to attach a listener to HttpApplication.BeginRequest results in one of two things, symptom 1 is that BeginRequest never fires, or symptom 2 is that the following exception gets thrown on all managed requests, and I cannot catch & handle it from user code: Stack Trace: [NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineModuleStepContainer.GetEventCount(RequestNotification notification, Boolean isPostEvent) +30 System.Web.PipelineStepManager.ResumeSteps(Exception error) +1112 System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +113 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +616 Commenting out app.BeginRequest += new EventHandler(this.OnBeginRequest) in Init stops the exception of course. Init does not reference the Context or Request objects at all. I have tried: Removed all references to HttpContext.Current anywhere in the project (still symptom 1) Tested removing all code from the body of my OnBeginRequest method, to ensure the problem wasn't internal to the method (= exception) Sniffing the stack trace and only calling app.BeginRequest+=... when if the stack isn't started by InitializeApplication (= BeginRequest not firing) Only calling app.BeginRequest+= on the second pass through Init (= BeginRequest not firing) Anyone know of a good approach? Is there some indirect strategy for hooking Application_Start within the module (seems unlikely)? Another event which a) one can hook from a module's constructor or Init method, and b) which is subsequently a safe place to attach BeginRequest event handlers? Thanks much

• TeamCity and pending Git merge branch commit keeps build with failed tests

  - by Vladimir

  We use TeamCity for continuous integration and Git for source control. Generally it works pretty well - convenient, modern and good us quick feedback when tests fails. There is a strange behavior related to Git merge specifics. Here are steps of the case: First developer pulls from master repo. Second developer pulls from master repo. First developer makes commit A locally. Second developer makes commit B locally; Second developer pushes commit B. First developer want to push commit A but unable because he have to pull commit B first. First developer pull's from remote reposity. First developer pushes commit A and generated merge branch commit. The history of commits in master repo is following: B second developer A first developer merge branch first developer. Now let's assume that Second Developer fixed some failing tests in his commit B. What TeamCity will do is following: Commit B arrives - TeamCity makes build #1 with all tests passed Commit A arrives - TeamCity makes build #2 (without commit B) test bar becomes Red! TeamCity thought that Pending "Merge Branch" commit doesn't contain any changes (any new files) - but it actually does contain the merge of commit B, so the TeamCity don't want to make new build here and make tests green. Here are two problems: 1. In our case we have failed tests returning back in second commit (commit A) 2. TeamCity don't want to make a new build and make tests back green. Does anybody know how to fix both of this problems. I consider some reasonable general approach.

• structured vs. unstructured data in db

  - by Igor

  the question is one of design. i'm gathering a big chunk of performance data with lots of key-value pairs. pretty much everything in /proc/cpuinfo, /proc/meminfo/, /proc/loadavg, plus a bunch of other stuff, from several hundred hosts. right now, i just need to display the latest chunk of data in my UI. i will probably end up doing some analysis of the data gathered to figure out performance problems down the road, but this is a new application so i'm not sure what exactly i'm looking for performance-wise just yet. i could structure the data in the db -- have a column for each key i'm gathering. the table would end up being O(100) columns wide, it would be a pain to put into the db, i would have to add new columns if i start gathering a new stat. but it would be easy to sort/analyze the data just using SQL. or i could just dump my unstructured data blob into the table. maybe three columns -- host id, timestamp, and a serialized version of my array, probably using JSON in a TEXT field. which should I do? am i going to be sorry if i go with the unstructured approach? when doing analysis, should i just convert the fields i'm interested in and create a new, more structured table? what are the trade-offs i'm missing here?

• Running multiple instances of tomcat in eclipse WTP

  - by lisak

  Hey, SCENARIO: 10 CATALINA_BASEs with own configuration (always the same port numbers 8080, but 10 different IP/hostnames on one host via virtual IPs). created a server in WTP and pick "Use the custom location" option in the server configuration in eclipse. New configuration files are created in workspace/Server/server-name-config/ Set up the server path and deploy path for my catalina base (not the internal .metadata one) After I started it, the new configuration files overwrote the original catalina-base/conf files I had there - I was glad, it should be like this but after I made changes in the eclipse config files workspace/Server/server-name-config/ and restarted the server, the changes didn't appeared in the original files in CATALINA_BASE/conf What the hell is that ? So I set the CATALINA_BASE/conf/server.xml to fault configuration and restarted tomcat from eclipse and it worked ! it took the configuration from /Server/server-name-config/server.xml Then I deleted CATALINA_BASE/conf/server.xml and it said that there is no server.xml in catalina base ! How is it possible ? I don't understand why eclipse WTP developers made so tight integration. There should by just symbolic links in /Server/server-name-config/ pointing to CATALINA_BASE/conf/ ... now there is a weird system which is totally unpredictable. The changes in /Server/server-name-config/ are not reflected in CATALINA_BASE/conf ... from where the standard bootstrap.jar or other catalina classloaders and classes build server, engine and other objects with particular setting. Moreover the CATALINA_BASEs could be used outside eclipse then. The second problem, I'm setting up various things in CATALINA_BASE/bin/startup.sh and setenv.sh which is easy cause I can use bash for it. Is then modifying VM parameters in the "Open launch configuration" settings the only way how to do it in eclipse ? Sorry for such a huge pile of questions, but I'm annoyed by the fact that it is much better to not use eclipse WTP for this because it is very poorly designed and it's a shame because this would spare me a lot of time. And using the internal .metadata/ instances it's even more terrifying way that the one I described.

• How do I get uri of HTTP packet with winpcap?

  - by Gtker

  Based on this article I can get all incoming packets. /* Callback function invoked by libpcap for every incoming packet */ void packet_handler(u_char *param, const struct pcap_pkthdr *header, const u_char *pkt_data) { struct tm *ltime; char timestr[16]; ip_header *ih; udp_header *uh; u_int ip_len; u_short sport,dport; time_t local_tv_sec; /* convert the timestamp to readable format */ local_tv_sec = header->ts.tv_sec; ltime=localtime(&local_tv_sec); strftime( timestr, sizeof timestr, "%H:%M:%S", ltime); /* print timestamp and length of the packet */ printf("%s.%.6d len:%d ", timestr, header->ts.tv_usec, header->len); /* retireve the position of the ip header */ ih = (ip_header *) (pkt_data + 14); //length of ethernet header /* retireve the position of the udp header */ ip_len = (ih->ver_ihl & 0xf) * 4; uh = (udp_header *) ((u_char*)ih + ip_len); /* convert from network byte order to host byte order */ sport = ntohs( uh->sport ); dport = ntohs( uh->dport ); /* print ip addresses and udp ports */ printf("%d.%d.%d.%d.%d -> %d.%d.%d.%d.%d\n", ih->saddr.byte1, ih->saddr.byte2, ih->saddr.byte3, ih->saddr.byte4, sport, ih->daddr.byte1, ih->daddr.byte2, ih->daddr.byte3, ih->daddr.byte4, dport); } But how do I extract URI information in packet_handler?

• JQuery Validation Plugin: Prevent validation issue on nested form

  - by Majid

  I have a form on which I use validation. This form has a section for photo upload. Initially this section contains six elements with the following code: <img class="photo_upload" src="image/app/photo_upload.jpg"> I have bound a function to the click event for the class of photo_upload. This function replaces the image with a minimal form with this code: Copy code <form onsubmit="startUploadImage();" target="control_target" enctype="multipart/form-data" method="post" action="index.php"> <input type="hidden" value="add_image" name="service"> <input type="hidden" value="1000000" name="MAX_FILE_SIZE"> <input type="file" size="10" name="photo" id="photo_file_upload"><br> <button onclick="javascript:cancel_photo_upload();return false;">Cancel</button> </form> So, essentially, after the image is clicked, I'd have a new form nested in my original, validated form. Now, when I use this new form and upload an image, I receive an error (repeated three times) saying: validator is undefined http://host.com/path/index.php Line 286 What is going on here? My guess is this Submit event bubbles up to the outer form As we have validation on that form, validation is triggered, Validation tries to find the form triggering it, Since we have not bound validation to the inner form it returns 'undefined' Now, is my assessment correct? Whether it is or not, how can I solve this issue?

• Java invokeAndWait of C# Action Delegate

  - by ikurtz

  the issue i mentioned in this post is actually happening because of cross threading GUI issues (i hope). could you help me with Java version of action delegate please? in C# it is done as this inline: this.Invoke(new Action(delegate() {...})); how is this achived in Java? thank you. public class processChatMessage implements Observer { public void update(Observable o, Object obj) { System.out.println("class class class" + obj.getClass()); if (obj instanceof String){ String msg = (String)obj; formatChatHeader(chatHeader.Away, msg); jlStatusBar.setText("Message Received"); // Show chat form setVisibility(); } } } processChatMessage is invoked by a separate thread triggered by receiving new data from a remote node. and i think the error is being produced as it trying to update GUI controls. do you think this is the reason? i ask because im new to Java and C#, but this is what is going on i think. SOLUTION: public class processChatMessage implements Observer { public void update(Observable o, Object obj) { if (obj instanceof String){ final String msg = (String)obj; try { SwingUtilities.invokeAndWait(new Runnable( ) { public void run( ) { formatChatHeader(chatHeader.Away, msg); jlStatusBar.setText("Message Received"); setVisibility(); } }); } catch (InterruptedException e){ } catch (InvocationTargetException e){ } } } }

• org.eclipse.jdt.ui.wizards.NewClassWizardPage available on Linux, but not on the Mac?

  - by Martin Cowie

  Most esteemed host of Eclipse magi .. I am trying to create an instance of the org.eclipse.jdt.ui.wizards.NewClassWizardPage class. I have one project where I do this, and it will compile & run on Linux, but not on a Mac. Both machines are running the Helios edition of Eclipse with the PDE, both were downloaded with the last week. The bundle org.eclipse.jdt.ui is available on the Mac, but for some reason the Mac will not compile the phrase import org.eclipse.jdt.ui.wizards.NewClassWizardPage; Saying "The import org.eclipse.jdt.ui.wizards.NewClassWizardPage cannot be resolved". The MANIFEST.MF is a simple one .. Manifest-Version: 1.0 Bundle-ManifestVersion: 2 Bundle-Name: RcpTest0 Bundle-SymbolicName: rcpTest0; singleton:=true Bundle-Version: 1.0.0.qualifier Bundle-Activator: rcptest0.Activator Require-Bundle: org.eclipse.ui, org.eclipse.core.runtime, org.eclipse.core.resources, org.eclipse.jdt, org.eclipse.jdt.core, org.eclipse.jdt.ui Bundle-ActivationPolicy: lazy Bundle-RequiredExecutionEnvironment: JavaSE-1.6 Your clues & boos are all most welcome.

• Google GWT cross-browser support: is it BS ?

  - by Tim

  I developed a browser-deployed full-text search app in FlashBuilder which communicates RESTfully with a remote web-server. The software fits into a tiny niche--it is for use with ancient languages not modern ones, and there's no way I'm going to make any money on it but I did spend a lot of time on it. Now that Apple won't allow Flash on the iPad, I'm looking for a 100% javascript solution and was led to consider GWT. It looked promising, but one of the apps being "showcased" as a stellar example of what can be done with GWT has this disclaimer on their website (names {removed} to protect the potentially innocent) : Your current web browser (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1045 Safari/532.5) is not officially supported by {company and product name were here}. If you experience any problems using this site please install either Microsoft Internet Explorer 6+ or Mozilla Firefox 3.5+ before contacting {product name was here} Support. What gives when GWT apps aren't "officially" supported on Chrome? What grade (A, B, C, D, F) would you give to GWT for cross-browser support? For folks who don't get these kinds of letter grades, A is "excellent" and "F" is failure, and "C" is average. Thanks for your opinions.

• Why wouldn't a flex remoteobject be able to work within a custom component?

  - by Gary

  Please enlighten this flex noob. I have a remoteobject within my main.mxml. I can call a function on the service from an init() function on my main.mxml, and my java debugger triggers a breakpoint. When I move the remoteobject declaration and function call into a custom component (that is declared within main.mxml), the remote function on java-side no longer gets called, no breakpoints triggered, no errors, silence. How could this be? No spelling errors, or anything like that. What can I do to figure it out? mxml code: < mx:RemoteObject id="myService" destination="remoteService" endpoint="$(Application.application.home}/messagebroker/amf" > < /mx:RemoteObject > function call is just 'myService.getlist();' when I move it to a custom component, I import mx.core.Application; so the compiler doesn't yell my child component: child.mxml <mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()" > <mx:Script> <![CDATA[ import mx.core.Application; public function init():void { helloWorld.sayHello(); } ]]> </mx:Script> <mx:RemoteObject id="helloWorld" destination="helloService" endpoint="$(Application.application.home}/messagebroker/amf" /> <mx:Label text="{helloWorld.sayHello.lastResult}" /> </mx:Panel> my main.mxml: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()" xmlns:test="main.flex.*" > <mx:Script> <![CDATA[ [Bindable] public var home:String; [Bindable] public var uName:String; public function init():void { //passed in by wrapper html home = Application.application.parameters.appHome; uName = Application.application.parameters.uName; } ]]> </mx:Script> <test:child /> </mx:Application>
