  • JavaOne Session Report: “50 Tips in 50 Minutes for GlassFish Fans”

    - by Janice J. Heiss
    At JavaOne 2012 on Monday, Oracle’s Engineer Chris Kasso, and Technology Evangelist Arun Gupta, presented a head-spinning session (CON4701) in which they offered 50 tips for GlassFish fans. Kasso and Gupta alternated back and forth with each presenting 10 tips at a time. An audience of about (appropriately) 50 attentive and appreciative developers was on hand in what has to be one of the most information-packed sessions ever at JavaOne!Aside: I experienced one of the quiet joys of JavaOne when, just before the session began, I spotted Java Champion and JavaOne Rock Star Adam Bien sitting nearby – Adam is someone I have been fortunate to know for many years.GlassFish is a freely available, commercially supported Java EE reference implementation. The session prioritized quantity of tips over depth of information and offered tips that are intended for both seasoned and new users, that are meant to increase the range of functional options available to GlassFish users. The focus was on lesser-known dimensions of GlassFish. Attendees were encouraged to pursue tips that contained new information for them. All 50 tips can be accessed here.Below are several examples of more elaborate tips and a final practical tip on how to get in touch with these folks. Tip #1: Using the login Command * To execute a remote command with asadmin you must provide the admin's user name and password.* The login command allows you to store the login credentials to be reused in subsequent commands.* Can be logged into multiple servers (distinguish by host and port). Example:     % asadmin --host ouch login     Enter admin user name [default: admin]>     Enter admin password>     Login information relevant to admin user name [admin]     for host [ouch] and admin port [4848] stored at     [/Users/ckasso/.asadminpass] successfully.     Make sure that this file remains protected.     Information stored in this file will be used by     asadmin commands to manage the associated domain.     Command login executed successfully.     % asadmin --host ouch list-clusters     c1 not running     Command list-clusters executed successfully.Tip #4: Using the AS_DEBUG Env Variable* Environment variable to control client side debug output* Exposes: command processing info URL used to access the command:                           http://localhost:4848/__asadmin/uptime Raw response from the server Example:   % export AS_DEBUG=true  % asadmin uptime  CLASSPATH= ./../glassfish/modules/admin-cli.jar  Commands: [uptime]  asadmin extension directory: /work/gf-3.1.2/glassfish3/glassfish/lib/asadm      ------- RAW RESPONSE  ---------   Signature-Version: 1.0   message: Up 7 mins 10 secs   milliseconds_value: 430194   keys: milliseconds   milliseconds_name: milliseconds   use-main-children-attribute: false   exit-code: SUCCESS  ------- RAW RESPONSE  ---------Tip #11: Using Password Aliases * Some resources require a password to access (e.g. DB, JMS, etc.).* The resource connector is defined in the domain.xml.Example:Suppose the DB resource you wish to access requires an entry like this in the domain.xml:     <property name="password" value="secretp@ssword"/>But company policies do not allow you to store the password in the clear.* Use password aliases to avoid storing the password in the domain.xml* Create a password alias:     % asadmin create-password-alias DB_pw_alias     Enter the alias password>     Enter the alias password again>     Command create-password-alias executed successfully.* The password is stored in domain's encrypted keystore.* Now update the password value in the domain.xml:     <property name="password" value="${ALIAS=DB_pw_alias}"/>Tip #21: How to Start GlassFish as a Service * Configuring a server to automatically start at boot can be tedious.* Each platform does it differently.* The create-service command makes this easy.   Windows: creates a Windows service Linux: /etc/init.d script Solaris: Service Management Facility (SMF) service * Must execute create-service with admin privileges.* Can be used for the DAS or instances* Try it first with the --dry-run option.* There is a (unsupported) _delete-serverExample:     # asadmin create-service domain1     The Service was created successfully. Here are the details:     Name of the service:application/GlassFish/domain1     Type of the service:Domain     Configuration location of the service:/work/gf-3.1.2.2/glassfish3/glassfish/domains     Manifest file location on the system:/var/svc/manifest/application/GlassFish/domain1_work_gf-3.1.2.2_glassfish3_glassfish_domains/Domain-service-smf.xml.     You have created the service but you need to start it yourself. Here are the most typical Solaris commands of interest:     * /usr/bin/svcs  -a | grep domain1  // status     * /usr/sbin/svcadm enable domain1 // start     * /usr/sbin/svcadm disable domain1 // stop     * /usr/sbin/svccfg delete domain1 // uninstallTip #34: Posting a Command via REST* Use wget/curl to execute commands on the DAS.Example:  Deploying an application   % curl -s -S \       -H 'Accept: application/json' -X POST \       -H 'X-Requested-By: anyvalue' \       -F id=@/path/to/application.war \       -F force=true http://localhost:4848/management/domain/applications/application* Use @ before a file name to tell curl to send the file's contents.* The force option tells GlassFish to force the deployment in case the application is already deployed.* Use wget/curl to execute commands on the DAS.Example:  Deploying an application   % curl -s -S \       -H 'Accept: application/json' -X POST \       -H 'X-Requested-By: anyvalue' \       -F id=@/path/to/application.war \       -F force=true http://localhost:4848/management/domain/applications/application* Use @ before a file name to tell curl to send the file's contents.* The force option tells GlassFish to force the deployment in case the application is already deployed.Tip #46: Upgrading to a Newer Version * Upgrade applications and configuration from an earlier version* Upgrade Tool: Side-by-side upgrade– GUI: asupgrade– CLI: asupgrade --c– What happens ?* Copies older source domain -> target domain directory* asadmin start-domain --upgrade* Update Tool and pkg: In-place upgrade– GUI: updatetool, install all Available Updates– CLI: pkg image-update– Upgrade the domain* asadmin start-domain --upgradeTip #50: How to reach us?* GlassFish Forum: http://www.java.net/forums/glassfish/glassfish* [email protected]* @glassfish* facebook.com/glassfish* youtube.com/GlassFishVideos* blogs.oracle.com/theaquariumArun Gupta acknowledged that their method of presentation was experimental and actively solicited feedback about the session. The best way to reach them is on the GlassFish user forum.In addition, check out Gupta’s new book Java EE 6 Pocket Guide.

  • Different Not Automatically Implies Better

    - by Alois Kraus
    Originally posted on: http://geekswithblogs.net/akraus1/archive/2013/11/05/154556.aspxRecently I was digging deeper why some WCF hosted workflow application did consume quite a lot of memory although it did basically only load a xaml workflow. The first tool of choice is Process Explorer or even better Process Hacker (has more options and the best feature copy&paste does work). The three most important numbers of a process with regards to memory are Working Set, Private Working Set and Private Bytes. Working set is the currently consumed physical memory (parts can be shared between processes e.g. loaded dlls which are read only) Private Working Set is the physical memory needed by this process which is not shareable Private Bytes is the number of non shareable which is only visible in the current process (e.g. all new, malloc, VirtualAlloc calls do create private bytes) When you have a bigger workflow it can consume under 64 bit easily 500MB for a 1-2 MB xaml file. This does not look very scalable. Under 64 bit the issue is excessive private bytes consumption and not the managed heap. The picture is quite different for 32 bit which looks a bit strange but it seems that the hosted VB compiler is a lot less memory hungry under 32 bit. I did try to repro the issue with a medium sized xaml file (400KB) which does contain 1000 variables and 1000 if which can be represented by C# code like this: string Var1; string Var2; ... string Var1000; if (!String.IsNullOrEmpty(Var1) ) { Console.WriteLine(“Var1”); } if (!String.IsNullOrEmpty(Var2) ) { Console.WriteLine(“Var2”); } ....   Since WF is based on VB.NET expressions you are bound to the hosted VB.NET compiler which does result in (x64) 140 MB of private bytes which is ca. 140 KB for each if clause which is quite a lot if you think about the actually present functionality. But there is hope. .NET 4.5 does allow now C# expressions for WF which is a major step forward for all C# lovers. I did create some simple patcher to “cross compile” my xaml to C# expressions. Lets look at the result: C# Expressions VB Expressions x86 x86 On my home machine I have only 32 bit which gives you quite exactly half of the memory consumption under 64 bit. C# expressions are 10 times more memory hungry than VB.NET expressions! I wanted to do more with less memory but instead it did consume a magnitude more memory. That is surprising to say the least. The workflow does initialize in about the same time under x64 and x86 where the VB code does it in 2s whereas the C# version needs 18s. Also nearly ten times slower. That is a too high price to pay for any bigger sized xaml workflow to convert from VB.NET to C# expressions. If I do reduce the number of expressions to 500 then it does need 400MB which is about half of the memory. It seems that the cost per if does rise linear with the number of total expressions in a xaml workflow.  Expression Language Cost per IF Startup Time C# 1000 Ifs x64 1,5 MB 18s C# 500 Ifs x64 750 KB 9s VB 1000 Ifs x64 140 KB 2s VB 500 Ifs x64 70 KB 1s Now we can directly compare two MS implementations. It is clear that the VB.NET compiler uses the same underlying structure but it has much higher offset compared to the highly inefficient C# expression compiler. I have filed a connect bug here with a harsher wording about recent advances in memory consumption. The funniest thing is that one MS employee did give an Azure AppFabric demo around early 2011 which was so slow that he needed to investigate with xperf. He was after startup time and the call stacks with regards to VB.NET expression compilation were remarkably similar. In fact I only found this post by googling for parts of my call stacks. … “C# expressions will be coming soon to WF, and that will have different performance characteristics than VB” … What did he know Jan 2011 what I did no know until today? ;-). He knew that C# expression will come but that they will not be automatically have better footprint. It is about time to fix that. In its current state C# expressions are not usable for bigger workflows. That also explains the headline for today. You can cheat startup time by prestarting workflows so that the demo looks nice and snappy but it does hurt scalability a lot since you do need much more memory than necessary. I did find the stacks by enabling virtual allocation tracking within XPerf which is still the best tool out there. But first you need to look at your process to check where the memory is hiding: For the C# Expression compiler you do not need xperf. You can directly dump the managed heap and check with a profiler of your choice. But if the allocations are happening on the Private Data ( VirtualAlloc ) you can find it with xperf. There is a nice video on channel 9 explaining VirtualAlloc tracking it in greater detail. If your data allocations are on the Heap it does mean that the C/C++ runtime did create a heap for you where all malloc, new calls do allocate from it. You can enable heap tracing with xperf and full call stack support as well which is doable via xperf like it is shown also on channel 9. Or you can use WPRUI directly: To make “Heap Usage” it work you need to set for your executable the tracing flags (before you start it). For example devenv.exe HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\devenv.exe DWORD TracingFlags 1 Do not forget to disable it after you did complete profiling the process or it will impact the startup time quite a lot. You can with xperf attach directly to a running process and collect heap allocation information from a gone wild process. Very handy if you need to find out what a process was doing which has arrived in a funny state. “VirtualAlloc usage” does work without explicitly enabling stuff for a specific process and is always on machine wide. I had issues on my Windows 7 machines with the call stack collection and the latest Windows 8.1 Performance Toolkit. I was told that WPA from Windows 8.0 should work fine but I do not want to downgrade.

  • Beyond Cloud Technology, Enabling A More Agile and Responsive Organization

    - by sxkumar
    This is the second part of the blog “Clouds, Clouds Everywhere But not a Drop of Rain”. In the first part,  I was sharing with you how a broad-based transformation makes cloud more than a technology initiative, I will describe in this section how it requires people (organizational) and process changes as well, and these changes are as critical as is the choice of right tools and technology. People: Most IT organizations have a fairly complex organizational structure. There are different groups, managing different pieces of the puzzle, and yet, they don't always work together. Provisioning a new application therefore may require a request to float endlessly through system administrators, DBAs and middleware admin worlds – resulting in long delays and constant finger pointing.  Cloud users expect end-to-end automation - which requires these silos to be greatly simplified, if not completely eliminated.  Most customers I talk to acknowledge this problem but are quick to admit that such a transformation is hard. As hard as it may be, I am afraid that the status quo is no longer an option. Sticking to an organizational structure that was created ages back will not only impede cloud adoption,  it also risks making the IT skills increasingly irrelevant in a world that is rapidly moving towards converged applications and infrastructure.   Process: Most IT organizations today operate with a mindset that they must fully "control" access to any and all types of IT services. This in turn leads to people clinging on to outdated manual approval processes .  While requiring approvals for scarce resources makes sense, insisting that every single request must be manually approved defeats the very purpose of cloud. Not only this causes delays, thereby at least partially negating the agility benefits, it also results in gross inefficiency. In a cloud environment, self-service access should be governed by policies, quotas that the administrators can define upfront . For a cloud initiative to be successful, IT organizations MUST be ready to empower users by giving them real control rather than insisting on brokering every single interaction between users and the cloud resources. Technology: From a technology perspective, cloud is about consolidation, standardization and automation. A consolidated and standardized infrastructure helps increase utilization and reduces cost. Additionally, it  enables a much higher degree of automation - thereby providing users the required agility while minimizing operational costs.  Obviously, automation is the key to cloud. Unfortunately it hasn’t received as much attention within enterprises as it should have.  Many organizations are just now waking up to the criticality of automation and it still often gets relegated to back burner in favor of other "high priority" projects. However, it is important to understand that without the right type and level of automation, cloud will remain a distant dream for most enterprises. This in turn makes the choice of the cloud management software extremely critical.  For a cloud management software to be effective in an enterprise environment, it must meet the following qualifications: Broad and Deep Solution It should offer a broad and deep solution to enable the kind of broad-based transformation we are talking about.  Its footprint must cover physical and virtual systems, as well as infrastructure, database and application tiers. Too many enterprises choose to equate cloud with virtualization. While virtualization is a critical component of a cloud solution, it is just a component and not the whole solution. Similarly, too many people tend to equate cloud with Infrastructure-as-a-Service (IaaS). While it is perfectly reasonable to treat IaaS as a starting point, it is important to realize that it is just the first stepping stone - and on its own it can only provide limited business benefits. It is actually the higher level services, such as (application) platform and business applications, that will bring about a more meaningful transformation to your enterprise. Run and Manage Efficiently Your Mission Critical Applications It should not only be able to run your mission critical applications, it should do so better than before.  For enterprises, applications and data are the critical business assets  As such, if you are building a cloud platform that cannot run your ERP application, it isn't truly a "enterprise cloud".  Also, be wary of  vendors who try to sell you the idea that your applications must be written in a certain way to be able to run on the cloud. That is nothing but a bogus, self-serving argument. For the cloud to be meaningful to enterprises, it should adopt to your applications - and not the other way around.  Automated, Integrated Set of Cloud Management Capabilities At the root of many of the problems plaguing enterprise IT today is complexity. A complex maze of tools and technology, coupled with archaic  processes, results in an environment which is inflexible, inefficient and simply too hard to manage. Management tool consolidation, therefore, is key to the success of your cloud as tool proliferation adds to complexity, encourages compartmentalization and defeats the very purpose that you are building the cloud for. Decision makers ought to be extra cautious about vendors trying to sell them a "suite" of disparate and loosely integrated products as a cloud solution.  An effective enterprise cloud management solution needs to provide a tightly integrated set of capabilities for all aspects of cloud lifecycle management. A simple question to ask: will your environment be more or less complex after you implement your cloud? More often than not, the answer will surprise you.  At Oracle, we have understood these challenges and have been working hard to create cloud solutions that are relevant and meaningful for enterprises.  And we have been doing it for much longer than you may think. Oracle was one of the very first enterprise software companies to make our products available on the Amazon Cloud. As far back as in 2007, we created new cloud solutions such as Cloud Database Backup that are helping customers like Amazon save millions every year.  Our cloud solution portfolio is also the broadest and most deep in the industry  - covering public, private, hybrid, Infrastructure, platform and applications clouds. It is no coincidence therefore that the Oracle Cloud today offers the most comprehensive set of public cloud services in the industry.  And to a large part, this has been made possible thanks to our years on investment in creating cloud enabling technologies. I will dedicated the third and final part of the blog “Clouds, Clouds Everywhere But not a Drop of Rain” to Oracle Cloud Technologies Building Blocks and how they mapped into our vision of Enterprise Cloud. Stay Tuned.

  • C++ : C++ Primer (Stanley Lipmann) or The C++ programming language (special edition)

    - by Kim
    I have a Computer Science degree (long2 time ago) .. I do know Java OOP but i am now trying to pick up C++. I do have C and of course data structure using C or pascal. I have started reading Bjarne Stroustrup book (The C++ Programming Language - Special Edition) but find it extremely difficult esp. some section which i don't have exposure such as Recursive Descent Parser (chapter 6). In terms of the language i don't foresee i have problem but i have problem as mentioned cos' those topic are usually covered in a Master Degree program such as construction of compiler. I just bought a book called C++ primer (Stanley Lipmann) which i heard it is a very good book for C++. Only setback is it's of course no match with the amount of information from the original C++ creator. Please advice. Thanks.

    I was trying to set the ViewController with a parent view controller before it shows show that it can provide call backs, I done this using PrepareForSegue - (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([segue.identifier isEqualToString:@"newQuarter"]) { [segue.destinationViewController setParentViewController:self]; } } It crashed giving me the error message: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Application tried to present modally an active controller. So I tried using another method and set up a new view controller on the button touches up, - (IBAction) buttonClicked { NewViewController *newController = [[NewViewController alloc] init]; [newController setParentViewController:self]; [self presentViewController:newController animated:YES completion:nil]; } but with no luck it is still giving me the same error message, can anyone please advice? Thanks!

  • Using Javascript to call the Azure Blob Storage REST API

    - by user350829
    I'm developing a Flash app that saves files to the Azure Blob Storage API. I've learned that you should use the REST API directly rather than a go-between WCF service as this is the most efficient (using a web role is a bottleneck). The problem is that Flash can't do PUT or DELETE methods over Http and has to use external Javascript. This is not an area that I'm familiar with and need some advice/links to examples of using Javascript to work with the Storage API (I've obviously Googled this to no avail). Is this even possible? The Javascript would be hosted in a web role on the same domain. Many thanks, Ed

  • Problem running iPhone application on iPhone from Xcode (and in Instruments)

    - by Ben
    Hi I have a problem running one application on the iPhone from Xcode (or Instruments). When I try to run the app I get the error message Failed to upload XXX.app in the bottom left corner of Xcode. The strange thing is it actually uploaded the app to the iPhone but it doesn't start it (after this I can start the app by hand on the iPhone). So without being able to start the app from Xcode or instruments I have no chance of debugging/performance testing. Any advice on what might be going wrong here? The iPhone console shows me this: Thu Oct 1 14:25:18 unknown mobile_installationd[1976] <Error>: 00808e00 install_embedded_profile: Skipping the installation of the embedded profile Thu Oct 1 14:25:23 unknown SpringBoard[25] <Warning>: Reloading and rendering all application icons. Other applications work fine. I've tried this on two iPhones (both 3.1) with the same result. I am running Xcode 3.2 on SnowLeopard. Regards

  • WPF Combobox textbox not updating when binding changes.

    - by WillH
    I have a WPF CombBox as follows: <ComboBox ItemsSource="{Binding Source={StaticResource myList}}" SelectedItem="{Binding Path=mySelectedItem}" /> The problem I have is that when the bound value changes, the selected value in the combobox's textbox does not update. (Note - the values in the combobox list do update). I am using MVVM so I can detect in the view model when the binding changes and call a property changed event and this is updating the combobox, but not the value displayed within the textbox. I think this could be done in the template of the combobox - somehow make the textbox be bound to the selecteditem of the combobox, or always update when it updates? I don't know how to do this though so any advice would be most appreciated.

  • Couldn't attachto Firefox 3.x browser by using Browser.AttachTo<FireFox>method in WatiN 2.0 RC1

    - by Shu Yang
    I am using HTTPWatch automation API to launch a new Firefox instance like that: HttpWatch.Controller ct = new HttpWatch.Controller(); HttpWatch.Plugin plugin = ct.FireFox.New(""); plugin.GotoURL("http://www.google.com"); These codes could start a Firefox browser successfully. Then I want to control the browser in WatiN 2.0: FireFox ff = Browser.AttachTo<FireFox>(Find.ByTitle("Google")); WatiN could not find Firefox window (JSSH plugin has been added in Firefox). But the same test on IE 7 is ok. I even tried to open a Firefox window manually and visit google.com page. WaitN in IE7 could attach to the browser, but Firefox failed. Is there anything wrong with my codes? Or any other advice? Thanks in advance! Here is the config for my environment: OS: Windows XP Pro SP2 WatiN: 2.0 RC1 Browser: IE 7, Firefox 3.0/3.5/3.6 with JSSH plugin

  • Wicket, Spring and Hibernate - Testing with Unitils - Error: Table not found in statement [select re

    - by John
    Hi there. I've been following a tutorial and a sample application, namely 5 Days of Wicket - Writing the tests: http://www.mysticcoders.com/blog/2009/03/10/5-days-of-wicket-writing-the-tests/ I've set up my own little project with a simple shoutbox that saves messages to a database. I then wanted to set up a couple of tests that would make sure that if a message is stored in the database, the retrieved object would contain the exact same data. Upon running mvn test all my tests fail. The exception has been pasted in the first code box underneath. I've noticed that even though my unitils.properties says to use the 'hdqldb'-dialect, this message is still output in the console window when starting the tests: INFO - Dialect - Using dialect: org.hibernate.dialect.PostgreSQLDialect. I've added the entire dump from the console as well at the bottom of this post (which goes on for miles and miles :-)). Upon running mvn test all my tests fail, and the exception is: Caused by: java.sql.SQLException: Table not found in statement [select relname from pg_class] at org.hsqldb.jdbc.Util.sqlException(Unknown Source) at org.hsqldb.jdbc.jdbcStatement.fetchResult(Unknown Source) at org.hsqldb.jdbc.jdbcStatement.executeQuery(Unknown Source) at org.apache.commons.dbcp.DelegatingStatement.executeQuery(DelegatingStatement.java:188) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.initSequences(DatabaseMetadata.java:151) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.(DatabaseMetadata.java:69) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.(DatabaseMetadata.java:62) at org.springframework.orm.hibernate3.LocalSessionFactoryBean$3.doInHibernate(LocalSessionFactoryBean.java:958) at org.springframework.orm.hibernate3.HibernateTemplate.doExecute(HibernateTemplate.java:419) ... 49 more I've set up my unitils.properties file like so: database.driverClassName=org.hsqldb.jdbcDriver database.url=jdbc:hsqldb:mem:PUBLIC database.userName=sa database.password= database.dialect=hsqldb database.schemaNames=PUBLIC My abstract IntegrationTest class: @SpringApplicationContext({"/com/upbeat/shoutbox/spring/applicationContext.xml", "applicationContext-test.xml"}) public abstract class AbstractIntegrationTest extends UnitilsJUnit4 { private ApplicationContext applicationContext; } applicationContext-test.xml: <?xml version="1.0" encoding="UTF-8"? <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd" <bean id="dataSource" class="org.unitils.database.UnitilsDataSourceFactoryBean"/ </beans and finally, one of the test classes: package com.upbeat.shoutbox.web; import org.apache.wicket.spring.injection.annot.test.AnnotApplicationContextMock; import org.apache.wicket.util.tester.WicketTester; import org.junit.Before; import org.junit.Test; import org.unitils.spring.annotation.SpringBeanByType; import com.upbeat.shoutbox.HomePage; import com.upbeat.shoutbox.integrations.AbstractIntegrationTest; import com.upbeat.shoutbox.persistence.ShoutItemDao; import com.upbeat.shoutbox.services.ShoutService; public class TestHomePage extends AbstractIntegrationTest { @SpringBeanByType private ShoutService svc; @SpringBeanByType private ShoutItemDao dao; protected WicketTester tester; @Before public void setUp() { AnnotApplicationContextMock appctx = new AnnotApplicationContextMock(); appctx.putBean("shoutItemDao", dao); appctx.putBean("shoutService", svc); tester = new WicketTester(); } @Test public void testRenderMyPage() { //start and render the test page tester.startPage(HomePage.class); //assert rendered page class tester.assertRenderedPage(HomePage.class); //assert rendered label component tester.assertLabel("message", "If you see this message wicket is properly configured and running"); } } Dump from console when running mvn test: [INFO] Scanning for projects...

  • Silverlight Project - Slide-in and out Panel - How?

    - by user118190
    I don't know what exactly this feature is, but I would like to simulate this in my Silverlight project. I am a C# developer and am moving to Silverlight and Expression Studio (Blend) for richer UX. Let's say I have some user controls and would like them to come into the screen (slide-in and out) as shown in the following site I found: http://www.templatemonster.com/silverlight-templates/28722.html On the menu, as one clicks on the menu item, the 'screen' slides to the left and then a new 'screen' slides in from the left to right. I really want to learn this stuff, but don't know what these 'features' are called? For example what are these 'screens' called in the xaml world? Also, what is the 'slide-in/out' called in the xaml world? Can someone point me to a good article/whitepaper? Thanks in advance for any advice.

  • Acrobat Reader ActiveX in WebBrowser stealing focus [C#]

    - by Maciej
    I'm using webBrowser.Navigate(url) control to display page. I noticed this action steals focus from current control (grid) and than I have problem to focus grid back (tired myGrid.Focus, .Select etc...) This is really annoying behaviour of browser... Does anyone knows how to prevent focus stealing by Browser or (if not) hot to force to focus control back ? EDIT: I've also tried webBrowser.DocumentCompleted event to focus back to grid EDIT 2 Good case to test this is openning PDF files webBrowser.Navigate(@"C:\TEMP\test.pdf") I believe this is ActiveX issue. On first glance it looks that this is not problem with focusing control but loosing entire Form focus... EDIT 3 I tried another approach: Form keyPress event: I thought I can capture form's keyPress and move focus from WebBrowser / AdobeReader ActiveX to my control. But surprisingly event is not fired! Looks Reader taken all control and there is no way to do anything programically until you do mouse click on (at least) form's caption Any advice (s) ?

  • Rails: savage_beast forum plugin and tinymce - new post works but edit doesn't use tinymce properly

    - by Max Williams
    Hi all. I'm using the savage_beast forum plugin and tinymce (via the tinymce_hammer plugin) in my rails app. When posting a new post, tinymce works fine. However, when i go to edit a post i get the tinymce editor, but the content in the edit box has all been converted into html. Can anyone tell me how i get it so that what appears in the tinymce edit box is the original text i posted, rather than the converted-to-html version? Does it need to get converted back from html into a format tinymce will use? Savage_beast saves the original given text in a body field, and the converted-to-html text in a body_html field. After tinymce does its work in the first instance (ie when posting a new post) the body field gets text that's already been converted to html. So i guess i need to convert it back to whatever tinymce expects? I'd expect tinymce to be happy with getting html, and to just handle it, though. grateful for any advice - max

  • Machine learning challenge: diagnosing program in java/groovy (datamining, machine learning)

    - by Registered User
    Hi All! I'm planning to develop program in Java which will provide diagnosis. The data set is divided into two parts one for training and the other for testing. My program should learn to classify from the training data (BTW which contain answer for 30 questions each in new column, each record in new line the last column will be diagnosis 0 or 1, in the testing part of data diagnosis column will be empty - data set contain about 1000 records) and then make predictions in testing part of data :/ I've never done anything similar so I'll appreciate any advice or information about solution to similar problem. I was thinking about Java Machine Learning Library or Java Data Mining Package but I'm not sure if it's right direction... ? and I'm still not sure how to tackle this challenge... Please advise. All the best!

  • In my WCF service with IXmlSerializable class, I get ArrayOfXElement[] instead of ObservableCollecti

    - by Scott
    I have an existing class (I didn't write) that implements IXmlSerializable. I decided to create a WCF service so my Silverlight application could access this class. I return the class as List. In the generated proxy, instead of an ObservableCollection like I'm expecting, I get ArrayOfXElement[]. If I remove the IXmlSerializable attribute, I get an the ObservableCollection. I don't quite understand what is happening, but I just want my SL app to receive an ObservableCollection. Is my only choice to create a DTO class and send back a list of those? Any advice?

  • How to convert Silverlight XAML to Resource dictionary in Silverlight 2

    - by Vecdid
    I am looking for the quickest and easiest way to combine two silverlight projects. Once has controls all in Silverlight XAML the other is template driven and uses a template based on a Silverlight resource dictionary. I am looking for some advice and resources on the best and quickest way to do this. One project is based on this: Silverlight Image Slider http://www.silverlightshow.net/items/Image-slider-control-in-Silverlight-1.1.aspx the other project is based on this: Open Video Player http://www.openvideoplayer.com/ I need to move the slider into the player, but the player uses a template and I just don't get how to merge the two as I do not understand resource dictionaries as they are applied to the player. We have completely gutted and made each proiject do what we want, but heck if I can figure out how to combine them.

  • SUBSONIC 3.0.0.3 Subsonic.Query.SqlQuery

    - by dancingn27
    New to subsonic and having issues figuring it out. I am simply just trying to do a distinct search and any documentation I find is telling me to use the class/method SubSonic.SqlQuery Though I am finding out that since I am using the newest version, a lot of the documentation I am finding does not apply. For example, I am getting this query working beautifully using Subsonic.Query.SqlQuery though there is NO distinct method hanging off of it as suggested by what I have seen. Please advice! SubSonic.Query.SqlQuery query = brickDB.SelectColumns(new string[] { "DomainName" }).From<Web.Data.DB.WebLog>() .Where(Web.Data.DB.WebLogTable.DomainNameColumn).IsNotNull(); -> No distinct hanging off of From<>()....

  • CSS: Setting width/height as Percentage minus pixels

    - by Mega Matt
    Hi all, I've seen this question asked in a couple other contexts on SO, but I thought it would be worth asking again for my particular case. I'm trying to create some re-usable CSS classes for more consistency and less clutter on my site, and I'm stuck on trying to standardize one thing I use frequently. I have a container div that I don't want to set the height for (because it will vary depending on where on the site it is), and inside it is a header div, and then an unordered list of items, all with CSS applied to them. It looks a lot like this: I want the unordered list to take up the remaining room in the container div, knowing that the header div is 18px tall. I just don't know how to specify the list's height as "the result of 100% minus 18px". Does anyone have any advice in this situation? Thanks very much.

  • Xcode warning: application executable contains unsupported architecture(s):arm, arm (-19031)

    - by rmvz3
    Hi all. I've been receiving this warning since I loaded my project in last Xcode 4 preview. There was no warning before that but now I can't get rid of it even in Xcode 3.2. I've been googling but nobody seems to have the same error. My project and target settings are correct (IMHO): Architectures: Standard (armv6 armv7), Base SDK: Latest iOS (currently set to iOS 4.2), Build Active Architecture Only: FALSE, Valid Architectures: armv6 armv7. I compared every project setting with other projects and and found no differences. I even have recreated the project starting from scratch and copying classes, resources and frameworks with the same result. I must say that the warning is not shown when I set Debug configuration. I hope someone can help me because I don't know what to do. Thanks in advice.

  • Android TranslateAnimation resets after animation

    - by monmonja
    I'm creating something like a SlideDrawer but with most customization, basically the thing is working but the animation is flickering at the end. To further explain, I got an TranslateAnimation then after this animation it returns back to the original position, if i set setFillAfter then the buttons inside the layout stops working. If i listen to onAnimationEnd and set other's layout to View.GONE the layout fickers. Judging from it is that on animation end, the view goes back to original position before the View.GONE is called. Any advice would be awesome. Thanks

  • VB.NET DownloadDataAsync:

    - by Brett
    Hi everybody, I am having the worst trouble getting around a bug, and am hoping that I can get some advice on this site. In short, I am trying to make an asynchronous web service call from my VB.NET application. But my "client_DownloadDataCompleted" callback is NEVER being called when the download is complete. Here is my complete code: Public Sub BeginAsyncDownload(ByVal Url As String) Dim waiter As System.Threading.AutoResetEvent = New System.Threading.AutoResetEvent(False) Dim client As WebClient = New WebClient() 'client_DownloadDataCompleted method gets called when the download completes. AddHandler client.DownloadDataCompleted, AddressOf client_DownloadDataCompleted Dim uri As Uri = New Uri(Url) Downloading = True 'Class variable defined elsewhere client.DownloadDataAsync(uri, waiter) End Sub Private Sub client_DownloadDataCompleted(ByVal sender As Object, ByVal e As AsyncCompletedEventArgs) MessageBox.Show("Download Completed") Downloading = False Debug.Print("Downloaded") End Sub Again, the client_DownloadDataCompleted method is never being called. I have also tried using the method: Private Sub client_DownloadDataCompleted(ByVal sender As Object, ByVal e As DownloadDataCompletedEventArgs) With no luck. What I really need is that "Downloading" variable to be switched off when the download is complete. Thanks in advance! Brett

  • Processing a tab delimited file with shell script processing

    - by Lilly Tooner
    Hello, normally I would use Python/Perl for this procedure but I find myself (for political reasons) having to pull this off using a bash shell. I have a large tab delimited file that contains six columns and the second column is integers. I need to shell script a solution that would verify that the file indeed is six columns and that the second column is indeed integers. I am assuming that I would need to use sed/awk here somewhere. Problem is that I'm not that familiar with sed/awk. Any advice would be appreciated. Many thanks! Lilly

  • What is the single best free Eclipse plugin for a Java developer

    - by Bill Michell
    Some Eclipse plugins are mandated by your environment. The appropriate source code management plugin, for example - and I'm not interested in those. Some provide useful enhancements, but in a specific niche. I'm not interested in those. Some are great, but cost money. I'm not interested in those. Some were really useful on older versions of Eclipse, but are now part of the core build of the latest Eclipse version (3.4 as I write this). I'm not interested in those. I want advice on which plugins every Java SE developer should be installing, one per answer please.
