    Cannot get JSTL tags to print variable values.

    Roland Brown Newbie

      How do you set intelliJ up to use these tags.

      I completed the following.

      1. I have integrated JBOSS into intellij.
      2. I can already use servlets and JSP with in my Intellij environment.
      3. I have downloaded JSTL 1.1 and moved the two .jar files (jstl.jar and standard.jar) to the the jboss/server/default/deploy folder.
      4. I copied all eight .tld files into the web_inf folder of my IntelliJ web module.
      5. Modified my web.xml file to include all the TLD files as follows for all eight.


      6. Added the jstl.jar and standard.jar files to the Module Libraries in the Libraries(Classpath) tab.

      Before I did step 6 anytime I tried using jstl tags the text was set to red. After 6 the code was able to find the tag information.

      Everything compiles fine. But the tag code is being piped out like it is just a string.

      For example:
      <c-rt:forEach var="person" items="<%= names %>"> c:out value="${person}"

      names is an array of strings. The code just prints out ${person} instead of the value it represents. The code compiles and JBOSS starts up completely clean. Any help would be appreciatted. I am using JBOSS 4.01.

          I don't have the code with me right now. I will post it tonight.

            I solved the problem or I should say a really great customer support rep at Jet Brains and another support person at http://www.fuhrer.com/en/jbossplugin/.

            The problem was that when I had set up my web module I had configured it to use version 2.3. Version 2.3 does not support JSTL tags. If you try to use them the data will be passed right through like it is a string.

            Basically I removed the web module and then readded it using version 2.4.

            My web.xml file now looks like the following.

            <?xml version="1.0" encoding="UTF-8"?>
            <web-app version="2.4"
             xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >

            My JSTLExample.jsp files looks like this.

             Created by IntelliJ IDEA.

             String[] names = {"Ruth", "Matilda", "Millicent", "Micah"};
             <head><title>JSTL example</title></head>
             <c:forEach var="person" items="<%= names %>">
             <c:out value="${person}" />

            In the web Modules setting in the Libraries(Classpath) window I have added the following Jar/Directorys. I moved the jar and tld files from JAKARTA 1.1.2 unzipped folder before adding these jar/directory.


            My project was created in the webquotes folder.

            In the Web Module Settings tab of the web Modules window I made the following change under the Modules and Libraries to Package section.

            Name Packing Method Relative
            jstl.jar Copy files to /WEB-INF/lib/jstl.jar
            standard.jar Copy files to /WEB-INF/lib/standard.jar
            d:\projects\webquotes\jstl\tld Copy dir to /META-INF/tld

            After making these changes the JSTL worked.

            I used the following.
            Intellij 4.5.4
            Jboss 4.01sp1
            Latest JBOSS plugin
            Java jdk 1.4.2_07

              I had read somewhere that you did not have to include the tld files in the .war file to use JSTL. I experimented some more and found this to be the case. The only thing I had to do was make sure the standard.jar and jstl.jar files were put into the WEB-INF\lib folder. It is simpler than I thought.
