Craig,
I'm not an h/c jsp programmer...I just play one on netbeans ;)
Can you explain how to do this? I'm mucking around with jsp:expression and jsp:declaration tags and I'm having trouble accessing the " currentRow.value[..." variable, setting a new variable with the urlencoded value, and getting that value in the javascript.

Hi Craig,
Thanks. That worked. Sort of. If I type in a browser "modulename=Hello%20World", moduleName gets set to "Hello World". I'm calling the page, however, from within a table in javascript:
src=moduleerrors.jsp?modulename=#{currentRow.value['modulename']}
moduleName gets set to "Hello"...everything after the space is gone.
You need to URL encode the parameter value ... otherwise the space will be treated as the end of the URL. See the javadocs for java.net.URLEncoder.

Any ideas?

Pretty simple prerender method for the moduleerrors.jsp:
public void prerender() { try { String moduleName = getValue("#{requestScope.modulename}").toString(); } catch (Exception e) { e.printStackTrace(); } }
When I try to access:
moduleerrors.jsp?modulename=foo
I get a null pointer exception because getValue("#{requestScope.modulename }") is returning a null value
This seems real simple. Any ideas what I might be doing wrong?
Yep. You are trying to access a request *parameter*, but requestScope references a request *attribute*. Try this instead:
getValue("#{param.modulename}");
