RE: error in strutsel-exercise-taglib
John, Another David here. I'm learning how to use the Expression Language 'stuff' in Tomcat 5.0.X (.28 actually) under Struts v1.2.4 and I'm NOT using Struts-El. I don't need it. I'm not sure about HashMaps as I haven't used them yet, but I can access my variables without Struts-el this way: My actual for in struts-config.xml is named "uploadForm". I'm sorry about the stupid field called "name" but hey, I'm playing around with it! In my upload.jsp page, I can access the members of the uploadForm either the old way: *** Keep in mind I still have a tag *** so the *** below html:text tag works properly *** and pulls the form bean in that is *** associated with the /upload action. OR I can do it using the JSP 2.0 expression language syntax: Again, I DO NOT use Struts-el, just the stock struts. I do have one change in my WEB-INF/web.xml file. Instead of having: I changed it to: http://java.sun.com/xml/ns/j2ee"; version="2.4"> That change, after restarting my webapp, allowed me to use expression language variables in any of my JSP files. I hope this information helps you.

You don't need to use Struts-EL with Tomcat 5, if you're using JSP 2.0. In fact, it won't work. I don't know what this particular exception is, but you can avoid this situation entirely by just not doing it. > -Original Message- > From: John C Cartwright [mailto:[EMAIL PROTECTED] > > Hello All, > > I tried deploying the example webapp that comes with the > contrib/struts-el taglibs and am getting the following exception > accessing the index.jsp: > > java.lang.NullPointerException > org.apache.struts.taglib.TagUtils.pageURL(TagUtils.java:1114) > > org.apache.struts.taglib.TagUtils.computeURLWithCharEncoding(T > agUtils.java:466) > > org.apache.struts.taglib.TagUtils.computeURLWithCharEncoding(T > agUtils.java:329) > > org.apache.struts.taglib.html.LinkTag.calculateURL(LinkTag.java:475) > > org.apache.struts.taglib.html.LinkTag.doStartTag(LinkTag.java:334) > > org.apache.strutsel.taglib.html.ELLinkTag.doStartTag(ELLinkTag > .java:666) > > org.apache.jsp.index_jsp._jspx_meth_html$1el_link_0(index_jsp. > java:146) > org.apache.jsp.index_jsp._jspService(index_jsp.java:118) > > org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:94) > javax.servlet.http.HttpServlet.service(HttpServlet.java:810) > > org.apache.jasper.servlet.JspServletWrapper.service(JspServlet > Wrapper.java:298) > > org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet > .java:292) > > org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236) > javax.servlet.http.HttpServlet.service(HttpServlet.java:810) > > > Can anyone suggest what the problem might be?
