Re: [jetty-users] Custom SessionHandler in Jetty
|
Thank you for the quick response. Your guessing right, the session handler is located within the project.
I followed your advice and exported the custom sessionhandler to a jar file ("jar -cf myhandler-0.1-jar [Class]"). Then I manually installed the jar to my local repository and added it as a dependency to the project. I verfied that the dependency was found and loaded by turning on the maven debug options. Still, I'm getting the same error. Here's the full stacke trace:
Failed to execute goal org.mortbay.jetty:jetty-maven-plugin:7.3.1.v20110307:run-exploded (default-cli) on project : Unable to parse configuration of mojo org.mortbay.jetty:jetty-maven-plugin:7.3.1.v20110307:run-exploded for parameter sessionHandler: ClassNotFoundException: Class name which was explicitly given in configuration using 'implementation' attribute: 'net.synchronite.jetty.SessionHandler' cannot be loaded -> [Help 1]

The relevant secrtion in the pom looks like this:
<webAppConfig>
<contextPath>/</contextPath>
<extraClasspath>D:\myhandler-0.1.jar</extraClasspath>
<sessionHandler implementation="net.synchronite.jetty.SessionHandler">
<sessionManager implementation="net.synchronite.jetty.SessionManager">
</sessionManager>
</sessionHandler>
</webAppConfig>
Is there any other way of registering my own session handler in Jetty 7.3.1? Maybe using a context listener?
Thanks for your help!
