Passing a list of beans to jsp

[Jesse Snadden]

Hello,
could someone tell me what the best way is for passing a list of objects (beans) to a jsp page? It's not working for me

My servlet code

   response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        String page = "ViewGrpCrt.jsp";
        try {
            
            List list;
            DataAccess da = new DataAccess();
            list = da.readAllGrpCrts();
           

            out.println(((groupCertBean)list.get(0)).getFolderRef().toString() + "<br/>");
            out.println(((groupCertBean)list.get(0)).getGrpCrtAlias().toString());

            request.setAttribute("grpCrt", list);
            RequestDispatcher dispatcher = request.getRequestDispatcher(page);
            if (dispatcher != null){
                dispatcher.forward(request, response);
           }
        } 
        catch (Exception E) {
        }
        finally {
                  }

The out.println is just to prove that the information is getting passed to the servlet from my dataAccess page that talks to the server, but when I try using the request dispatcher and request.setattribute stuff, it gives me a blank page...

Here is what is happening on my jsp page I'm trying to send this list of objects to

<table>
    <tr>
        <td>Folder Reference</td>
        <td>Alias</td>
        <td>Custodian</td>
        <td>LRA</td>
    </tr>

<c:forEach items="${grpCrt}" var="grpCrt">
    <tr>
        <td width="119">${grpCrt.getFolderRef}</td>
        <td width="168">${grpCrt.getGrpCrtAlias} </td>
        <td width="119">${grpCrt.getGrpCrtCustodian} </td>
        <td width="168">${grpCrt.getLraUid} </td>
    </tr>
</c:forEach>
</table>

${grpCrt.getFolderRef} would call a method named getGetFolderRef() on grpCrt. This isn't what you want. ${grpCrt.folderRef} is better. Also, using the same name for the list and item in the list is confusing. (and I'm not sure if it works.) I recommend a different name.

thanks... ok this works and gives me the first line... now how do I iterate through them all?

<c:forEach items="${grpCrt}" var="cert">
    <tr>
        <td >${grpCrt[0].folderRef}</td>
        <td >${grpCrt[0].grpCrtAlias} </td>
        <td >"${grpCrt[0].grpCrtCustodian}</td>
        <td >${grpCrt[0].lraUid}</td>
    </tr>
</c:forEach>

tried this and get nothing in my table

<c:forEach items="${grpCrt}" var="cert">
    <tr>
        <td width="119"><c:out value="${cert.folderRef}"/></td>
        <td width="168"><c:out value="${cert.grpCrtAlias}"/> </td>
        <td width="119"><c:out value="${cert.grpCrtCustodian}"/></td>
        <td width="168"><c:out value="${cert.lraUid}"/></td>
    </tr>
</c:forEach>

I'm missing something...

ha... turns out my problem was that I didn't have the jstl jar files in my tomcat 6.0.18 lib directory... geeeeez...

Thanks for the help anyhow.
