JSTL with Liferay

To configure JSTL Core library with Liferay require following steps

Step 1 : Add jstl-api.jar and jstl-impl.jar into your liferay-plugin-package.properties file
            /WEB-INF/liferay-plugin-package.properties
             or
             copy both these jars into your project - /WEB-INF/lib folder


Step 2 : Include following syntax to JSTL Core library in your JSP:
             <%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c"%>

e.g        Set attribute in your java class
                      Employee e1 =new Employee(1, "Tanaji", "Mumbai");
                      List<Employee> empList = new ArrayList<Employee>();
                      empList.add(e1);
                      request.setAttribute("employeeList", empList);               

            Now you can use JSTL tag directly in your JSP file like this....
             <c:forEach var="emp" items="${employeeList}" >
                     Employee Name :-> <c:out value="${emp.name}"></c:out>
            </c:forEach>
            

Running Two Tomcat Instances Under Same LIFERAY_HOME Directory

1) Configure different ports for each tomcat

2) If consider both the tomcat under following directory like

   “…..../liferayHome/liferay-portal-6.1.1-ce-ga2-node1”
   “…..../liferayHome/liferay-portal-6.1.1-ce-ga2-node2”
   Here “liferayHome” is a home folder for both the tomcat server


3) Created two folders datanode1 and datanode2 under the “…..../liferayHome” home folder

    “…..../liferayHome/datanode1”
    “…..../liferayHome/datanode2”

4) Please add following properties in liferay-portal-6.1.1-ce-ga2-node1 portal-ext.properties file
   liferay.home=…..../liferayHome
   jdbc.default.url=jdbc:hsqldb:${liferay.home}/datanode1/hsql/lportal
   lucene.dir=${liferay.home}/datanode1/lucene/
   jcr.jackrabbit.repository.root=${liferay.home}/datanode1/jackrabbit
   dl.hook.file.system.root.dir=${liferay.home}/datanode1/document_library

5) Please add following properties in liferay-portal-6.1.1-ce-ga2-node2 portal-ext.properties file
    liferay.home=…..../liferayHome
    jdbc.default.url=jdbc:hsqldb:${liferay.home}/datanode2/hsql/lportal
    lucene.dir=${liferay.home}/datanode2/lucene/
    jcr.jackrabbit.repository.root=${liferay.home}/datanode2/jackrabbit
    dl.hook.file.system.root.dir=${liferay.home}/datanode2/document_library

6) Please restart both tomcats.
