Hi,
Maybe this question was posted already. I am sorry for the repetition.
Can somebody suggest what is the best case to resolve this expression

html:hidden property="domainID" value='%= bean:message

value of domainID is still %=
I have never been able to get that to work, I think
it's an issue with either tomcat of the java spec.
The way I have been able to get around this is to
write my own tag and have the tag set page context
attributes via a tag extra info class.

It isn't a struts problem, it is a problem caused by using excessive custom
jsp tags. One fix is to break your page up over several pages and use
dynamic includes. This will fix he compilation problems, but introduces a
few new challenges. The problem you are dealing with is the 64k limit in

There is a limit to the size of a compiled method in java, I think it's 64k,
it's probably not specifically related to the try/catch block. Split it up
into multiple jsp's and use includes to make it into one page. It seems to

I think, you are correct to qualify this as a formatting. Take the

Thank you for your reply, but this didn't really answer my question. Let me
