how to pass parameter from dispatchto javascript

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.
