java - javax.security.auth.login.LoginException: No LoginModules configured for SomeLogin -

well i'm trying create jaas authentication servlet (running on tomcat 7 in eclipse), i'm getting error.

he're's complete stack trace: '`

in context.xml:

<realm classname="org.apache.catalina.realm.jaasrealm"  appname="gdialogin" userclassnames="org.ktu.gdia.core.security.userprincipal" roleclassnames="org.ktu.gdia.core.security.roleprincipal" /> 

in jaas.config (i'm pretty sure tomcat finds correctly because added correct path arguments "run configurations" in eclipse):

  gdialogin {     org.ktu.gdia.core.security.gdialoginmodule required debug=true; }; 

i'm assuming there has wrong jaas.config...

my login module, not sure if need provide here, though, it's straight tutorial i've been following:

edit: run configuration arguments in eclipse tomcat:

-dcatalina.base="d:\dropbox\eclipseworkspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp7" -dcatalina.home="d:\servers\gentreeuploader_tomcat7" -dwtp.deploy="d:\dropbox\eclipseworkspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp7\wtpwebapps" -djava.endorsed.dirs="d:\servers\gentreeuploader_tomcat7\endorsed" -djava.security.auth.login.config="d:\dropbox\eclipseworkspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp7\conf\jaas.config" 

well? ideas?

according http://tomcat.apache.org/tomcat-7.0-doc/realm-howto.html#jaasrealm

you should set login.config file java , tell tomcat find specifying location jvm, instance setting environment variable: java_opts=$java_opts -djava.security.auth.login.config=$catalina_base/conf/jaas.config

added

for windows open startup.bat add following line: set java_opts=%java_opts% -djava.security.auth.login.config=%catalina_home%/conf/jaas.config after okhome

e.g.

:okhome set java_opts=%java_opts% -djava.security.auth.login.config=%catalina_home%/conf/jaas.config set "executable=%catalina_home%\bin\catalina.bat"
