loader constraint violation: when resolving interface method "javax.servlet.jsp.JspApplicationContext.addELResolver(Ljavax/el/ELResolver;)V"

I got this error while deploying the WAR in Tomcat 7. I have carried out the development using JDeveloper 11.

"java.lang.LinkageError: loader constraint violation: when resolving interface method "javax.servlet.jsp.JspApplicationContext.addELResolver(Ljavax/el/ELResolver;)V" the class loader (instance of org/apache/catalina/loader/WebappClassLoader) of the current class, com/sun/faces/config/ConfigureListener, and the class loader (instance of org/apache/catalina/loader/StandardClassLoader) for resolved class, javax/servlet/jsp/JspApplicationContext, have different Class objects for the type p.JspApplicationContext.addELResolver(Ljavax/el/ELResolver;)V used in the signature"

I have googled for the answers and have found answers, but nothing seems to work for my problem. I understand that it is something to do with the JARs that I have in my /WEB-INF/lib, but I don't know which causes the error.

These are the JARs I have in /WEB-INF/lib:

  • adf-controller-api.jar
  • adf-controller-rt-common.jar
  • adf-controller-security.jar
  • adf-controller.jar
  • adf-dt-at-rt.jar
  • adf-richclient-api-11.jar
  • adf-richclient-impl-11.jar
  • adf-share-base.jar
  • adf-share-ca.jar
  • adf-share-security.jar
  • adf-share-support.jar
  • adf-transactions-dt.jar
  • adfdt_common.jar
  • adflibfilter.jar
  • adflogginghandler.jar
  • adfm.jar
  • adfmweb.jar
  • adfsharembean.jar

  • commons-el.jar
  • db-ca.jar
  • dvt-databindings.jar
  • dvt-faces.jar
  • dvt-facesbindings.jar
  • dvt-jclient.jar
  • dvt-trinidad.jar
  • dvt-utils.jar
  • glassfish.el_2.2.0.jar
  • glassfish.jsf_1.2.9.0.jar
  • glassfish.jstl_1.2.0.1.jar

  • javax.activation_1.1.0.0_1-1.jar
  • javax.ejb_3.0.1.jar
  • javax.jsf_1.0.0.0_1-2.jar
  • javax.jsp_1.1.0.0_2-1.jar
  • javax.servlet_1.0.0.0_2-5.jar
  • jdev-cm.jar
  • jewt4.jar
  • jsp-el-api.jar
  • ojdbc14.jar
  • ojmisc.jar
  • oracle-el.jar
  • oracle-page-templates.jar
  • share.jar
  • trinidad-api.jar
  • trinidad-impl.jar
  • wls.jsf.di.jar
  • xmlparserv2.jar

How can I solve it?

Solution

  • You should not have servletcontainer-specific libraries in your /WEB-INF/lib. At least the following ones are supposed to be already provided by Tomcat itself:

    • glassfish.el_2.2.0.jar
    • javax.jsp_1.1.0.0_2-1.jar
    • javax.servlet_1.0.0.0_2-5.jar
    • jsp-el-api.jar

    Remove them. The particular exception is caused by the javax.jsp_1.1.0.0_2-1.jar one, which is different from Tomcat's own one.
