The f=init function does not affect Java applications as it only reloads JavaScript, VBScript, and ACL custom applications. After an Arbortext PE 子进程 has started, its JVM can't reload a .class or .jar file from the PE_HOME\custom directory. You need to restart the servlet container to reload .class or .jar files in the Arbortext PE 子进程. For example, if you were using Tomcat, you would stop and restart it to reload your Java file.
