org.apache.jasper.JasperException

I used jstl in my jsp to pass parameter to my java program and get the output like this:
${sm:searcher_main(obj, obj.keyword)}
and it worked fine. But I need to pass another parameters so that I changed it to :
${sm:searcher_main(obj, obj.keyword, obj.content)}.
I also changed the code in my java program to accept two parameters. And I ve already changes it in my .tld file. But it doesn't work and I got the following error:

type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
