Recompile Java UDRs That Have Been Compiled Using JDK 1.4.x

When reverting to an older Dynamic Server versions, JAVA UDRs that have been compiled using JDK 1.4.x must be recompiled with older JDK versions. What you do depends on whether your application uses external JAR/class files or JAR files installed on the server:

• If your application uses external JAR/class files (for example, JAR/class files that are listed in JVPCLASSPATH), just recompile the JAR/class.
• If your application uses JAR files installed in the server (for example, via the install_jar() support function), then you must remove the old JAR file (using remove_jar() support function) and re-install the re-compiled JAR file in the database.
