jsp-tags

I have a requirement where in the JSP page itself is created by the user and stored in the database. When viewing results we need to render this JSP to the client, evaluating all tags inside this JSP.

I am aware that it is doable as OpenCMS and Blogger both implement this functionality. But, I just can't find the right way.

Any pointers on how to do this?

[Added] Note: I cannot write a temporary file on disk for the purpose :(

how to prevent jsp tags from being reused after being classloaded

as seen on Stack Overflow - Search for 'Stack Overflow'

So attributes that i do not set in later invocations are not null like i would… >>> More
