The auto-generation of the java source code is as follows:

• Auto-generation in the JSP specifications
  In the JSP specifications, the java source code is automatically generated in the _jspService method or the doTag method from the contents described in the JSP file or tag file.
  
• Auto-generation when the custom tag is used in the Application Server
  In the Application Server, if the custom tag is used, the processing of the custom tag and contents described in the body are changed into a method and the java source code is automatically generated.
  The custom tag can be converted into a method when the processing of the custom tag or all the custom tags included in the body fulfill the following conditions:
  
  • The attribute and body are scriptless.
  • The script variable is not defined.

When the number of lines of the methods for auto-generated java source code exceeds 1000 lines, including the comments and blank lines, the messages KDJE39231-W and KDJE39333-W are output.

If a message is output, review the body contents of the JSP file, tag file, or the custom tag.

The following are the reviewing methods for each location to be reviewed:

• When the size of the JSP file contents is big
  Divide the JSP file using dynamic include (include action).
  
• When the size of the tag file contents is big
  Implement one of the followings:
  
  • Divide the tag files used from the JSP file into multiple tag files.
  • Divide the tag files such that another tag file is invoked from the tag file.
• When the size of the custom tag body is big
  Divide the custom tag using dynamic include (include action).
