By default, Integration Server disables the Tomcat invoker servlet mapping. You can enable the servlet mapping by editing the web.xml file in the Integration Server_directory \instances\instance_name\web\conf directory. However, this is a security risk as it allows disclosure of the JSP source code. Because JSP source code is sometimes sensitive (especially if it includes passwords for back-end systems), avoid disclosing the JSP source code by leaving the invoker servlet mapping disabled.
