    JBoss 4.05GA + JPortal 2.4 & javascript problem

    Gaetano Sferra Newbie

      Hi,
      I wish to include a javascript file into a JSP portlet so I added the following on top of my JSP page:

      <%@taglib uri="http://java.sun.com/portlet" prefix="portlet" %>
      
      <portlet:defineObjects/>
      <script type="text/javascript" src="/js/mylib.js"></script>
      ...
      


      When my portlet loads I got an "undefined object" javascript error while trying to invoke an object belonging to the included file (the same occurs if I try to use everything else - objects or functions - defined in that file).
      Every other script directly written in my JSP works well, such as:

      <script type="text/javascript">
      alert("Hey, this works");
      </script>
      


      Thinking about a path problem I also tryed that:

      <%@taglib uri="http://java.sun.com/portlet" prefix="portlet" %>
      
      <portlet:defineObjects/>
      <script type="text/javascript" src='<%= response.encodeURL(request.getContextPath() + "/js/mylib.js") %>'></script>
      ...
      


      achieving the same, identical and frustrating results.
      Please, help me, I really need to solve this matter.

      Thank you,

          Probably not the solution you were looking for, but this is what I did to get around not being able to figure out the path to my script:

          renderResponse.setProperty("HEADER_CONTENT", "<script type=\"text/javascript\">"+ script +"</script>");


          Above my script has been loaded off the file system by my portlet and I inject the script into the head "manually". Probably not an issue for a short script, but I would imagine that finding the correct path and setting that in your JSP is better in the long run when your server is under heavy use.

            Thank you nollie,
            your solution may be a good choice for short scripts (you could put it directly into the JSP without have to set the header content in the portlet methods) but I'm in dealing with a long script library and I wish to include it (yes, I know, it's the same because the browser must download the script file) gaining a better "human readable" html output. If someone else knows a better solution, please post it, otherwise I've no choice to put all the javascript code inside the JSP.
            :-(

              Replace the location /js/mylib.js with <%= renderRequest.getContextPath() %>/js/mylib.js i.e.



              <script type="text/javascript" src="<%= renderRequest.getContextPath() %>/js/mylib.js"></script>
