Expression Language not working in JSPs when using Wildfly


    • 4
    • Wildfly 10.0



      When running Liferay 7 GA2 on WildFly 10, using EL expressions in JSP pages will cause an error.

      This does not affect the Tomcat Bundle.

      Steps to reproduce

      This issue uses a demonstration LR7 Maven project. You will need Maven to compile it, or reproduce the issue by developing a MVC Portlet by hand. All you need to do is have a JSP view containing EL expressions.

      1. Install a vanilla Liferay 7 GA2 Wildfly bundle using a MySQL 5.7 database
      2. Install a vanilla Liferay 7 GA2 Tomcat bundle using a MySQL 5.7 database
      3. Clone the following repository : https://github.com/njuneau/lr7-test-project or create an MVC Portlet module having a JSP view and EL expressions
      4. Make sure you have the public Liferay maven repository configured in your settings
      5. Package the modules using the command "mvn -C clean package" in the parent project
      6. Deploy the 3 modules (portlet-remover-api-0.0.1.jar, portlet-remover-svc-0.0.1.jar and portlet-remover-web-0.0.1.jar) on the Tomcat server
      7. Add "category.training > Portlet Remover" to a page
      8. The portlet will work correctly
      9. Deploy the 3 modules (portlet-remover-api-0.0.1.jar, portlet-remover-svc-0.0.1.jar and portlet-remover-web-0.0.1.jar) on the WildFly server
      10. Add "category.training > Portlet Remover" to a page

      Expected result

      The portlet should work

      Actual result

      "Portlet Remover is temporarily unavailable." will be shown on the page while the following stack trace is shown:
