JSP isErrorPage Attribute

Hi, I am currently working w/ JSP's and I had a question regarding the "isErrorPage" attribute. I'm including the "isErrorPage=true" attrib to a common .jspf file that is called by all our error jsp's to enforce conformity.

The only problem is that some of these error jsp's already have the attribute defined in it. I don't want to touch these pages that already exist due to the large number of regression tests that would have to be run.

Is there any way that I can test for the existance of this attribute before I define it in my .jspf file?

isErrorPage="true" defines variable 'exception' of Throwable type. You may try to check if that variable was defined (via reflection for example). But in any way setting isErrorPage to true twice doesn't hurt.

Good idea on the reflection, however you cannot set isErrorPage more than once per page ...
