Hi Group,
Finally I found the answer for my above query.
By default, the JavaServer Pages (JSP) engine translates a requested JSP file, compiles the .java file, and loads the compiled servlet into the run-time environment. You can change the JSP engine default behaviour by indicating a JSP file should never be translated or compiled at run-time, even when a .class file does not exist.
If run-time compilation is disabled, you must precompile the JSP files, which provides the following advantages:
*Reduces compilation related disk operations.
*Minimizes disk storage requirements necessary for handling temporary .java files generated during a run-time compilation.
*Allows you to not include the JSP source files in the application.
*Allows verification that a JSP file compiled successfully before deploying and installing the application in WebSphere Application Server.
