I am trying to use JAAS to authenticate my users. My project is in GWT v2, which runs jetty. I use eclipse for development.
From http://code.google.com/p/google-web-toolkit/issues/detail?id=4462 I found out that jetty doesn’t like any realm definitions in web.xml, so I moved them to jetty-web.xml.
I keep getting ClassNotFound exceptions so I followed the advice here: communitymapbuilder.org/display/JETTY/Problems+with+JAAS+in+Jetty+6.0.0
However, I am still getting ClassNotFoundExceptionsHere in my jetty-web.xml file. How do I configure jetty to work jaas in GWT projects?
My jetty-web.xml file:
<Configure class="org.mortbay.jetty.webapp.WebAppContext">
<Set name="serverClasses">
<Array type="java.lang.String">
<Item>-org.mortbay.jetty.plus.jaas.</Item>
<Item>org.mortbay.jetty</Item>
<Item>org.slf4j.</Item>
</Array>
</Set>
<Get name="securityHandler">
<Set name="userRealm">
<New class="org.mortbay.jetty.plus.jaas.JAASUserRealm">
<Set name="name">xyzrealm</Set>
<Set name="LoginModuleName">xyz</Set>
<Set name="config"><SystemProperty name="jetty.home" default="."/>/WEB-INF/classes/jdbcRealm.properties</Set>
</New>
</Set>
<Set name="authenticator">
<New class="org.mortbay.jetty.security.FormAuthenticator">
<Set name="loginPage">/login.jsp</Set>
<Set name="errorPage">/error.jsp</Set>
</New>
</Set>
</Get>
Error I am receiving:
[WARN] Failed startup of context com.google.gwt.dev.shell.jetty.JettyLauncher$WebAppContextWithReload@1fcef4f7{/,/home/dev/workspace/project/war}

Apparently you need to include the optional ‘plus’ jar from the jetty’s /lib distribution for jaas to work. That made the classnotfound exception go away.
