If anyone can help me with this, it's stopping me from finishing key portions of my applicaiton! I'm new to struts, and I am trying to retrieve a parameter that is in the request scope from a tag library. Currently, I can print out the parameter on my jsp page using request.getParameter(name), but in my pageContext object in my tag library, I don't have the same list or request paramters, all I have are the Struts Form object, Bean object, and Error object. Somewhere Struts has overriden the default request object, and implemented it's own before my custom tag is called. Would someone please tell me how I can retrieve the JSP page's request attributes in my custom tag?

RE: HELP! get request parameter from a custom tag
There's a tag for this in the struts bean taglib. Bean:parameter Check it out: http://jakarta.apache.org/struts/userGuide/struts-bean.html#parameter Gary -Original Message- From: Kevin Williams [mailto:[EMAIL PROTECTED]] Sent: Friday, February 14, 2003 3:23 PM To: [EMAIL PROTECTED] Subject: HELP! get request parameter from a custom tag Hi, I apologize if this already was posted...I posted this earlier today, but did not get see it posted...

RE: HELP! get request parameter from a custom tag
Doh! It's amazing how hard it is to retrieve when you call getAttribute instead of getParameter! THANK YOU! This code snippet should do the job.

Would someone please tell me how I can retrieve the JSP page's request attributes in my custom tag? Struts does not (and indeed *can* not in a Servlet 2.2 / JSP 1.1 environment) override the request object. I suspect you might be getting confused between request *parameters* (things that came in on the original request) and request *attributes* (things an Action might have put there). From within a tag implementation, you can get to request parameters like this: String foo = pageContext.getRequest().getParameter(foo); While request attributes can be retrieved like this: String foo = pageContext.getAttribute(foo, PageContext.REQUEST_SCOPE); Because you mentioned request scope, I'm betting that the latter is what you really want to use.
