RE: Scripting variable is not generated

[Wei Zhao]

Hi Mark:

Thank you for your response. That definitely answered my question. 

Do you know what's the status on this issue? Is Tomcat not going to support the 
relevant code before 4.1? It will be a huge effort (if possible) to work around 
the problem using either of the ways described in the bug entries you provided.

Thanks

Wei
