Hi! OK, you may ignore my previous my previoius emails and I have re-installed Eclipse and the plugins to simulate the same problem.
The following are the steps I performed: 1) JAVA_HOME=C:\Program Files\Java\jdk1.5.0_11 2) Download Eclipse Java EE project bundle (J2EE-SDK-Callisto-322-win32.zip) from http://www.ibm.com/developerworks/eclipse/downloads/ 3) Search and install all updates of the currently installed features 4) In Eclipse, goto Window->Preferences...->Java-Installed JREs Add a new JRE (JRE home directory: C:\Program Files\Java\jdk1.5.0_11) Remove the existing JRE (C:\Program Files\Java\jre1.5.0_11) 5) In Eclipse, install the latest Maven Integration for Eclipse (0.0.10) from http://m2eclipse.codehaus.org/update/ 6) Restart Eclipse 7) In Windows, create a project > mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-app > mvn package 8) In Eclipse, create my-app project from existing source. There will be errors because JUnit dependencies are missing! 9) Right-click my-app, and select Maven2->Enable. 6/18/07 2:24:29 PM SGT: Reading /my-app/pom.xml 6/18/07 2:24:29 PM SGT: Updated model /my-app/pom.xml : com.mycompany.app:my-app:1.0-SNAPSHOT 6/18/07 2:24:29 PM SGT: Reading /my-app/pom.xml 10) Right-click my-app, and select Maven2->Update Source Folders 6/18/07 2:26:20 PM SGT: Reading /my-app/pom.xml 6/18/07 2:26:20 PM SGT: Generating sources /my-app/pom.xml 6/18/07 2:26:20 PM SGT: [INFO] Scanning for projects... 6/18/07 2:26:20 PM SGT: [INFO] -------------------------------------------- 6/18/07 2:26:20 PM SGT: [INFO] Building my-app 6/18/07 2:26:20 PM SGT: [INFO] task-segment: [process-test-resources] 6/18/07 2:26:20 PM SGT: [INFO] -------------------------------------------- 6/18/07 2:26:21 PM SGT: resources:resources 6/18/07 2:26:21 PM SGT: [INFO] Using default encoding to copy filtered resources. 6/18/07 2:26:21 PM SGT: compiler:compile 6/18/07 2:26:21 PM SGT: [INFO] Compiling 1 source file to C:\Documents and Settings\tjhoo\Desktop\my-app\target\classes 6/18/07 2:26:21 PM SGT: ERROR mojo-execute : compiler:compile : Compilation failure Unable to locate the Javac Compiler in: C:\Program Files\Java\jre1.5.0_11\..\lib\tools.jar Please ensure you are using JDK 1.4 or above and not a JRE (the com.sun.tools.javac.Main class is required). In most cases you can change the location of your Java installation by setting the JAVA_HOME environment variable. Is there anything I have overlook? On 6/16/07, hezjing <[EMAIL PROTECTED]> wrote:

In Eclipse->Windows->Preferences...->Java->Installed JREs, I have only one entry with JRE home directory pointing to C:\Program Files\Java\jdk1.5.0_12 my JAVA_HOME is C:\Program Files\Java\jdk1.5.0_12 and the eclipse.ini contains -vm "C:\Program Files\Java\jdk1.5.0_12\bin\java.exe" -vmargs -Xms40m -Xmx256m May I know what could be the problem? -- Hez
