how to pass parameter from dispatchto javascript

[reubin haz]

In a servlet, I use dispatch and forward to go to another jsp, which contains some javascript code.
I want to pass a parameter in the dispatch and to be used by javascript.

I tried to set the parameter in the url, like blah.jsp?param=value, the forwarded jsp page url ends with blah.jsp, string after '?' is lost. Why would it be like this?

Then I tried to set parameter in the request. the forwarded jsp's javascript still cannot get the parameter value, since I'm not using java to get parameter. I need use javascript.

Can someone help me on this? What's the correct way to set it so that the target jsp page's javascript can access the parameter values.

Thanks.

In Servlet:

   request.setAttribute("key","Object"); 

In Jsp:

  onclick = javascript:jsFunction('${key}') ;
