It is due to a MyEclipse (I am using My Eclipse 5.5.0 GA) defect.

http://www.myeclipseide.com/index.php?name=PNphpBB2&file=viewtopic&t=21403&start=0&postdays=0&postorder=asc&highlight=

Workaround:  add them under the jar files under lib folder in the boot configuration of Resin in MyEclipse.

Also there is another MyEclipse ‘defect’. By default, the deploy folder will be used to deploy the Eclipse Project.  But we need to update the resin.conf file to set up the correct value for ‘<web-app-deploy path=”deploy”/>’ .

We came across java.lang.ArrayIndexOutOfBoundsException when using Resin 4.0.8.   The root cause is a defect from Resin 4.0.8.  (http://bugs.caucho.com/view.php?id=4104) . The solution is upgrade the Resin to version 4.0.9

commit -m “commit message.” files
RA layer request failed
svn: Commit failed (details follow):
svn: PROPFIND request failed on ‘/repo/path/!svn/vcc/default’
svn: PROPFIND of ‘/repo/path/!svn/vcc/default’: Could not read status line: connection was closed by server. (http://example.com)

How to fix?

Looking at my SVN configurations I could only find the JavaHL option, no SVNKit available.

Note: This procedure requires restarting the JBoss application server.

Steps

1. In the \server\default\deploy\jbossweb-tomcat50.sar directory, locate and open the server.xml file.
2. Locate the block listed under the <!– A HTTP/1.1 Connector on port 8080 –> heading.

   Note: The specific port number and other settings may vary.

   This block should look like this:

   <!-- A HTTP/1.1 Connector on port 8080 -->

   <Connector port="8080" address="${jboss.bind.address}"

   maxThreads="400" minSpareThreads="100" maxSpareThreads="75"

   enableLookups="false" redirectPort="8443" acceptCount="100"

   connectionTimeout="20000" disableUploadTimeout="true"/>

3. Add the following parameters:

   compression="on" 

   socketBuffer="1045576" />

4. Save and close the server.xml file.
5. Restart JBoss.

Generate the Java Code
1. Menu Operation
Tools , Generate Object-Oriented Model, Detail, O/R Mapping,
Enable Transformations, Extended Model Definitions, O/R Mapping,      Hibernate

To be continued.

When I needed to add or modify a CSS property of an element in Google Web Toolkit (GWT), I’d always do it like this :

widget.getElement().setAttribute("style", "align:right;");

However, if there was already any style information for defined for that element, it would be overwritten. You could get the current attributes first and then readd them along with your new info but there is a much cleaner way :

widget.getElement().getStyle().setProperty("align", "right");

Important! Note that when setting a style property, your need to use camel case for the property name.

//WRONG!
myWidget.getElement().getStyle().setProperty("background-color", "red");
// RIGHT
myWidget.getElement().getStyle().setProperty("backgroundColor", "red");

MyEcipse 6.5 delivers Java enterprise developers new strategic application lifecycle management (ALM) features. In addition, it includes improvements of MyEclipse’s industry leading Java EE tools and 1-click Java application technology repository and runtime.

MyEclipse’s new ALM features are founded upon the integration of Maven2 project and build management tools for MyEclipse (Maven4MyEclipse).  Using Maven4MyEclipse developers can now develop Maven versions of MyEclipse Java and Java EE projects. This takes advantage of the full suite of rich MyEclipse application technology frameworks and tools in their MyEclipse Maven projects. Additionally, Maven4MyEclipse allows developers to seamlessly leverage their strategic Maven-based ALM processes from within MyEclipse.

MyEclipse Java EE tools include improved JSF & Facelets visual design and coding, Spring IDE 2.0 for MyEclipse with Spring Web Flow, Hibernate Tools 3.2 for MyEclipse, JSR 168 Portlet development tools, and new web.xml and JSP tag library (TLD) editors. Working through a partnership with ICEsoft, MyEclipse ICEfaces support has been updated to support visual design and deployment of the latest ICEfaces 1.7.0 JSF Ajax component library.

MyEclipse 1-click Java application technology services include a jar library repository of all Java EE and related technologies, e.g., Struts, Hibernate, … and an custom embedded Tomcat 6 server runtime for rapid testing of Java EE web applications and examples. The repository has been updated to jar libraries for Spring 2.5, Hibernate 3.2, Struts 1.3.8, JSR 168 Portlet API and JAX-WS 2.1. The integrated MyEclipse Tomcat 6 server has been updated with a JAX-WS 2.1 (Metro) runtime as well as a sample security realm for use by a soon to be release set of JAX-WS web services security examples.

MyEclipse 6.5 is built upon the Eclipse 3.3 and Web Tools 2.0.2 platforms, i.e., Europa distro. Backwards compatibility with MyEclipse versions 6.x – 4.x projects and features is maintained to the maximum degree possible.

• MyEclipse Educational Material (Tutorials, Demos, etc.)
• MyEclipse Support Forums

4. Known Issues

MyEclipse Installer

• Do not install MyEclipse into a folder that has Cyrillic characters in its path. In some cases MyEclipse will not launch correctly. Additionally the MyEclipse installer is not able to display the release notes.

Windows Vista Support

• See Matisse4Myclipse below for known issues.

Matisse4MyEclipse Known Issues

• Matisse4MyEclipse is not part of the primary MyEclipse download.  The instructions for downloading and installing Matisse4MyEclipse is provided in the MyEclipse Learning Center found in the Help Infocenter. Launch the Help Info Center (see Help > Help Contents). Then navigate to the help topic at “MyEclipse Learning Center > Swing Development > Getting Started”.
• The Form Editor rendering of modified custom sub-forms and Java beans is not automatically updated. You must close and reopen the Form Editor for the rendering to be updated and correctly rendered.
• M4ME has not been certified to run on Java SE 6. Therefore if Java 6 is detected the M4ME Form Editor will only operate in experimental mode. The main issue is that it can be difficult to open ctx-menus within the Form Editor.

Cross Platform Visual JSP/HTML Designer Known Issues

• Editing XHTML documents does not support code-assist of non-HTML tags.
• Struts and JSF custom tags do not render styleClass attributes in design view.
• Empty table cells are initially shown collapsed in design view.
• Cut/Copy/Paste of tables not fully supported.

AJAX Tools Issues

• Remote scripts loaded from Scripts view that are generated by a Servlet that contains breakpoints, will cause Remote Script to be blank when loaded in editor.
• Visual JSP/HTML Designer-Design View can’t be made editable when a JavaScript debugging thread is paused at a breakpoint which is loaded form a http:// based URL.
• The AJAX Web Browser will disabled to all user input when the JavaScript debugger attached to that browser is stopped at a JavaScript Breakpoint. To reenable user-input the JavaScript debug thread will have to be resumed.

MyEclipse on Linux Version Known Issues

• Linux Internal Web Browser Stability
  The Visual HTML Designer on Linux has exhibited rare stability problems on some systems. Until this matter is resolved the WYSIWYG design mode has been restricted to a source-only mode of operation. You can reenable the WYSIYWG design mode for experimental use by including the commandline flag: -D linux.experimental
• Linux Internal Web Browser Compatibility
  The Visual HTML Designer and AJAX tools on linux can sometimes have an incompatibility with the Eclipse internal web browser.  Please read this document for more information.
• Linux X86_64 Compatibility
  The Visual JSP/HTML Designer and AJAX tools are not available on the 64-bit versions of Eclipse on Linux X86_64.
• Flash plugin unavailable in AJAX Browser
  When loading a webpage that contains a flash plugin, you will be prompted to download a plugin.  You must press cancel to continue to use the browser as normal.  Also you will need to resize the window once to fix the blank page because of a painting problem. As a result the MyEclipse AJAX tutorial does not property function in the browser.

MyEclipse on Mac OS X Known Issues

• Due to MyEclipse instability issues on the Mac platform the current features are not available: Visual Web Designer, MyEclipse UML and Matisse4MyEclipse. We are working to resolve the instability issues as quickly as possible.
• Application servers and Derby server won’t be properly stopped if MyEclipse is shut down using “Quit” from the application menu, Dock or keyboard shortcut. Close all workbench windows for proper shut down. See Eclipse Bug#194146
• The MyEclipse AJAX Tools are available on the Mac platform as experimental features. Use the -Dmac.experimetal=true command line argument to enable this experimental feature set.

Hibernate Tools for MyEclipse Known Issues

• Bug #3858, It is possible to use a Hibernate 3.1 DTD that can result in an error on a Hibernate upgrade. To resolve the ambiguity MyEclipse chose to use the Hibernate 3.1 DTDs by default in the Hibernate editors.
• Locale specification must include country code When explicitly launching MyEclipse with the “-nl ” commandline arguments the locale must include country code, e.g., -nl en_EN or -nl ja_JP.
  Failure to include the locale country code will result in an error when the HQL Editor is launched.

MyEclipse CSS Editor

• If code folding is enable and the properties view is open, typing in the CSS editor can be very slow.  See Eclipse Bug#158877

MyEclipse Tomcat

• MyEclipse Tomcat will work with all Java 5 JDKs, however, if you wish to use a Java 6 JDK to run MyEclipse Tomcat, please use JDK 6 update 4 (1.6.0_04) or above to avoid JAX-WS API compatibility issues.

MyEclipse JPA

• Database VIEWs can not be accessed from the JPA Project>MyEclipse>Generate Entities… ctx-menu action. Instead navigate to the view(s) from the DB Browser and select the Reverse Engineer JPA action

MyEclipse ScreenCapture PRO

• The ScreenCapture PRO facility is only available on Windows XP and 2000. Vista support is planned.

 The first alternative is to work not with actual spreadsheet files but with comma-separated value (CSV) files instead. CSV is a popular file format for exchanging spreadsheets. Any worthy spreadsheet can export to and import from CSV files.

Furthermore, many third-party products that work with spreadsheets also support CSV. For example, most accounting packages can work with CSV files. Although CSV files are not XML, it is simple to convert them into XML files with tools such as XI (see Resources). The TopXML site also includes algorithms for a pure XSLT solution (see Resources).

Using CSV files is much more attractive for servers. For one thing, you are no longer limited to certain platforms. Instead, you are broadening the options for your users (who can now work with Lotus 1-2-3 and other spreadsheets as well as many third-party tools that also recognize the CSV format).

About the only downside with this solution is that your users must take the extra step of saving their data in CSV. In practice I have found that this is seldom a problem, but your mileage may vary.

String temp[] = name.split(“\\\\”);
if (temp.length > 1) {
name = temp[temp.length - 1];
}

regex为\\\\，因为在java中\\表示一个\，而regex中\\也表示\，所以当\\\\解析成regex的时候为\\。由于unix中file.separator为斜杠“/”，下面这段代码可以处理windows和unix下的所有情况：

String temp[] = name.replaceAll(“\\\\”,”/”).split(“/”);
if (temp.length > 1) {
    name = temp[temp.length - 1];
}
