Jetty embedded running using OpenJDK throws PWC6188

Question

I am running a web application that uses Jersey 1.19.4 and JSTL 1.2.

Here is the maven dependency tree for the Embedded jetty project.

Answer 1

org.eclipse.jetty:jetty-jsp:jar:9.2.26.v20180806:compile

All versions of artifacts from org.eclipse.jetty.* should be the same version.

Upgrade the above one to 9.4.14.v20181114 too.

Answer 2

Thanks a lot for the immediate reply.

I am using the GlassFish JSP Implementation and the most stable version that is available "org.eclipse.jetty:jetty-jsp:jar:9.2.26.v20180806:compile". https://mvnrepository.com/artifact/org.eclipse.jetty/jetty-jsp

I am running this embedded jetty program within Eclipse IDE 2018-09 using OpenJDK 11+28.

    java -version
    openjdk version "11" 2018-09-25
    OpenJDK Runtime Environment 18.9 (build 11+28)
    OpenJDK 64-Bit Server VM 18.9 (build 11+28, mixed mode)

The same issue while using Oracle JDK as well.

    java -version
    java version "11.0.2" 2018-10-16 LTS
    Java(TM) SE Runtime Environment 18.9 (build 11.0.2+7-LTS)
    Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+7-LTS, mixed mode)

The application successfully works when I use Oracle JDK 1.8

In order to work in JDK 11, I have to change TLD URI in JSP page to well know name and then copy the tld's under WEB-INF directory and refer explicitly in web.xml file.

JSP(no error),

<%@ taglib prefix="c" uri="jstl-core" %>
<%@ taglib prefix="fn" uri="jstl-functions" %>

web.xml

  <jsp-config>
    <taglib>
      <taglib-uri>jstl-core</taglib-uri>
      <taglib-location>/WEB-INF/c.tld</taglib-location>
    </taglib>
    <taglib>
      <taglib-uri>jstl-functions</taglib-uri>
      <taglib-location>/WEB-INF/fn.tld</taglib-location>
    </taglib>
  </jsp-config>

Earlier JSP (with error)

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

I am not sure I am doing the right thing here, if anyone has right solution please let me know.

Answer 3

Thanks a Lot Joakim, after changing to apache-jsp it works great. I have reverted back to use the URI in JSP.

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

Here is my new dependency tree for the Jetty Embedded project,

+- org.slf4j:slf4j-api:jar:1.7.25:compile
+- org.slf4j:slf4j-log4j12:jar:1.7.25:compile

I have also added the following in the embedded jetty server code,

//org.eclipse.jetty.webapp.WebAppContext
context.setAttribute("org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern", ".*/[^/]*jstl.*\\.jar$");

org.eclipse.jetty.webapp.Configuration.ClassList classlist = org.eclipse.jetty.webapp.Configuration.ClassList.setServerDefault(server);
classlist.addAfter("org.eclipse.jetty.webapp.FragmentConfiguration","org.eclipse.jetty.plus.webapp.EnvConfiguration", "org.eclipse.jetty.plus.webapp.PlusConfiguration");
classlist.addBefore("org.eclipse.jetty.webapp.JettyWebXmlConfiguration","org.eclipse.jetty.annotations.AnnotationConfiguration");

Please let me know if any changes required with the above approach.
