[opencms-dev] Re: JSTL Expression Language and OpenCms Macro Excpressions

[Fabian Huber]

Hello Toni,

* Yes, I reverted all my changes in the web.xml file.

* The start tag in the web.xml file is:
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="
http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">

* The jsp where the problem exists, doesn't use any taglib. The problem is,
when I try to use OpenCms Macro Expressions. Here is an example:

<%@ page session="false" %>
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>
    <jsp:useBean id="cms" class="org.opencms.jsp.CmsJspActionElement">

    <link rel="stylesheet" type="text/css"
href="sites/default/kljb/css/articlemodule.css">

    <%
        cms.init(pageContext, request, response);

         // get the template
        String template = cms.property("template", "search");

        // The page header
    cms.include(template, "head");
        // end of template head

    String number = "${number}";

    %>
    <h1> Gallery</h1>


    <cms:contentload collector="allInFolderDateReleasedDesc"
param="/kljb/gallery/photos/galery_${number}|photoalbum" editable="true">
    <table border="0" width="100%">
    <tr><td width="50%">
        <h2><cms:contentshow element="Title" /></h2>
    </td>
    <td>
        <cms:contentloop element="Thumbs">
        <cms:contentshow element="TextBottom" />
        </cms:contentloop>
    </td>
    </tr>
    <tr>
    <td>
        <cms:contentloop element="Thumbs">
        <cms:contentshow element="TextTop" />
        </cms:contentloop>
    </td>
    <td>
        <a href="<cms:link><cms:contentshow element="${opencms.filename}"
/></cms:link>">Ansehen</a>
    </td>

    </tr>
    </table>

    <br/><br/>

    </cms:contentload>




    <%

        // The page foot
        cms.include(template, "foot");

    %>

</jsp:useBean>


The JSTL Library is parsing this file and takes the parts underlined as
Expression Language. In fact, these parts are OpenCms Macro. Both languages
have the same syntax. So this is the problem. (I don't know, why the OpenCms
developers decided to take the syntax of Expression Language for Macro
Expression, too. Ist there any sense?)

You are working with macros in your jsp files and don't get this problem?

Fabian
