 Downloadable files
 
Abstract
No IllegalStateException thrown when doing JSP forward after response has been committed.
 
Download Description
PQ76408 resolves the following problem:

ERROR DESCRIPTION:
A JSP attempts to forward a request to another resource after the response has been committed. WebSphere allows the forward to succeed, but it should instead raise an IllegalStateException according to the J2EE specification.

This problem has been identified internally by defect 171672.

USERS AFFECTED:
WebSphere Application Server users who do a forward in a JSP to another resource when the response has been committed.

PROBLEM DESCRIPTION:
A JSP attempts to forward a request to another resource after the response has been committed. WebSphere allows the forward to succeed, but instead it should raise an IllegalStateException according to J2EE specification.

RECOMMENDATION:
The Web container can not detect if the response has been committed if the user does a forward with a wrapper or a forward happens in a JSP.

PROBLEM CONCLUSION:
The Web container has been modified to add a new check if the response has been committed when the forward happens in the JSP or with a wrapper.
