How to get all request parameters
Hi This is probably a stupid question, but how do I get all the parameters from the request with their value? I need some output like: parameter_1 = output_1 parameter_2 = output_2 etc. I know I can access a certain value with param.key - but a collection of all keys?

parameter_1 = output_1
parameter_2 = output_2
I know I can access a certain value with param.key - but a collection
of all keys
... is just ${param}, a Map of all request parameters (with single
values).

Re: FW: BUg in forEach tag of JSTL
Vishal, Many people in this community are willing to help you, but there are a few things you should know that will make it easier to get the support you are looking for. 1. Send questions to the proper alias Please post your questions/comments related to jakarta-taglibs to [EMAIL PROTECTED] 2. Provide pertinent information - Clear description of the problem - What specific error do you get - What version of the taglib and what platform - Sample code that shows the problem Also, in the case of 'standard', it is always a good idea to first try to run the standard-examples webapp that ships with the release. -- Pierre Pier Fumagalli wrote: Not acked.

JSTL expression evaluation fails under load
[Does this list require subscription in order to post? Most other
Jakarta lists don't.]
I'm getting erratic behavior from JSTL tags under Tomcat 4.1.12. When
under load, sometimes expressions fail to evaluate. This exception is
produced:
javax.servlet.ServletException: javax.servlet.jsp.JspException: An error
occurred while evaluating custom action attribute test with value
${threadTool.player.moderator}: An error occurred while getting
property player from an instance of class
com.maxis.tso.community.tool.ThreadTool (java.lang.NullPointerException)
at
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContex
tImpl.java:494)
at
org.apache.jsp.mb_posts_jsp._jspService(mb_posts_jsp.java:776)
at
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:136)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
It results in the page half-loading. Simply refreshing the page works.
The expression is valid! There is a
threadTool.getPlayer().isModerator().
I don't believe this behavior occurred under Tomcat 4.0.6.
Unfortunately I can't seem to get any of the deeper exceptions - that's
as deep as the stack trace reports.
Does anyone have any idea what might be wrong, or how to go about
diagnosing the error?
Thanks in advance,
Jeff Schnitzer

call a function to get all parameter names
then for each parameter name, make function call to retrieve its
value(s)
