Hello,
This post is about Composer (log, JDK/JRE), the famous Eclipse-based tool used to create/modify custom type, job/method, BOF, aspects,…etc via Documentum Project.
Composer Log
First, during the use of Composer for compilation, building or deployment of Documentum Project, the C:\temp\documentum\ (or /tmp/documentum/) contains the log files named dctm_tools_xxxxxxxx.log:
Composer JDK/JRE
Secondly, like Eclipse, Composer allows the configuration of JDK/JRE used:
- It is possible to specify the JDK used of Composer project in project properties:
- It is also possible to define the default JRE used for projects in Composer Preferences:
ERRORs:
The following errors are displayed if the JRE version on target docbase is incompatible/inconsistent with the Composer project’s JRE.
Error 1: deployment error
The following error “java.lang.UnsupportedClassVersionError: … : Unsupported major.minor version 51.0” occurs during the deployment of a project via Composer or Dardeployer:
…the detail of UnsupportedClassVersionError error is visible in Composer log file:
... [INFO] Java version: 1.6.0_45 (64 bit) [INFO] Java home: C:\Program Files\Java\jre6 ... ... [INFO] DematDClient install failed. [FATAL] An unexpected error has occurred during installation For more details, check the most recent error log located by default in 'C:\temp\documentum\'. [ERROR] com.emc.ide.logger.defaultimpl.DmLoggerDefault::getDefaultThrowableMessage (line 100) com.emc.ide.installer.InstallException: Unexpected error occurred during install. at internal.com.emc.ide.installer.DarInstaller.handleNetworkException(DarInstaller.java:753) ... Caused by: java.lang.UnsupportedClassVersionError: com/huo/java/lu/persistence/documentum/bof/FinishMethod : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) ...
Error 2: runtime error
The following error “java.lang.UnsupportedClassVersionError: Bad version number in .class file” occurs during the runtime for example, when the execution of a method via DQL:
2017-01-07 16:37:28,677 INFO [STDOUT] 2017-01-07 16:37:28,677 ERROR [http-0.0.0.0-9080-2] org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/DmMethods].[DoMethod] - "Servlet.service()" pour la servlet DoMethod a généré une exception java.lang.UnsupportedClassVersionError: Bad version number in .class file at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620)
For information, below the major.minor version of JRE/JDK:
- J2SE 8 = 52
- J2SE 7 = 51
- J2SE 6.0 = 50
- J2SE 5.0 = 49
- JDK 1.4 = 48
- JDK 1.3 = 47
- JDK 1.2 = 46
- JDK 1.1 = 45
SOLUTION:
Client / Composer IDE
- Check the JRE/JDK version used during the compilation of Documentum project in Project Properties:
- Check the default JRE/JDK version to use for the compilation of Documentum project in the Preferences of Composer:
DCTM Server
- Check the JDK/JRE version on the DCTM server in the boot.log file available in the folder [DCTM_INSTALL_FOLDER]\jbossx.y.z\server\DctmServer_MethodServer\log:
- Check the JDK/JRE version on the DCTM server via the java command : java -version
Action to do
