Re: [jetty-users] Unable to find LoginModule class, how to solve it?

[Guofeng Zhang <guofengzh@xxxxxxxxx>]

I can run my web app using jetty-maven-plugin by setting the following:

      <plugin>

        <groupId>org.mortbay.jetty</groupId>

        <artifactId>jetty-maven-plugin</artifactId>

        <configuration>

          ......

          <systemProperties>

             <systemProperty>

               <name>java.security.auth.login.config</name>

               <value>src/main/resources/jetty/jaas.conf</value>

            </systemProperty>

          </systemProperties>

        <dependencies>

           <dependency>

              <groupId>org.planner</groupId>

              <artifactId>org.planner.security</artifactId>

              <version>${project.version}</version>

          </dependency>

         </dependencies>

         ....

 </plugin>

But the above is only for the development. I want to test how it works in a production environment, so I run the following from the command line in jetty-distribution-8.0.1.v20110908 and got the login module class not found exception:

   java -Djava.security.auth.login.config=file://D:/projects/ap/jetty-distribution-8.0.1.v20110908/conf/jaas.conf -jar start.jar

here I copied my login moduel jar to jetty-distribution-8.0.1.v20110908/lib. JAASLoginService is configured in jetty-web.xml packaged in the war, so it should be well because it runs well with jetty-maven-plugin.

If I put my login module jar in  jetty-distribution-8.0.1.v20110908/lib/ext, the login module is founded when I did the log in operation on the web UI, but maybe it is the system class path, so I got Credential class not found exception.

It should be a class loader issue, but I am newer to Jetty, so I do not know where to put the jar in the jetty distribution.

Thanks for your response!

This is generally a classloader issue so make sure that your login
class in available where it should be.

as thomas said, how are you starting up jetty?

cheers,
