The Java Virtual Machine (JVM) is included in the Java 2 Standard Edition (J2SE) software, which is required by the Application Server. Because incorrect JVM settings will prevent the server from running, you should take care when changing these settings.
To configure the general settings of the JVM used by the Application Server:
The Application Server relies on the J2SE software. To verify that the J2SE version you specify is supported in this release, refer to the Release Notes. (See the link in the Further Information section.)
Note: If you enter a non-existent directory name or the installation directory name of an unsupported version of the J2SE software, then the Application Server will not start.
The Application Server runs the compiler when EJB components are deployed.
JPDA is used by application developers. For more information, see the Debugging J2EE Applications chapter of the Application Server Developer’s Guide. (For a link to the guide, see Further Information.)
The Application Server runs the rmic compiler when EJB components are deployed.
Each class must implement the com.sun.appserv.BytecodePreprocessor
interface. The classes are called in the order specified.
Tools such as profilers might require entries in the Bytecode Preprocessor field. Profilers generate information used to analyze server performance. For more information about profiling, see the Debugging J2EE Applications chapter of the Application Server Developer’s Guide.
