Configuration file for Loging modules NOT found

jaikiran Jul 19, 2005 9:22 AM

Hi,
I am doing a jaas login through my code. I have placed my class files in a jar file name myClient.jar. In the code i have set the config file as follows:

System.setProperty("java.security.auth.login.config","myConfig.conf");

I have placed this myConfig.conf file inside the myClient.jar and placed the myClient.jar in my classpath.

I get the following error during login:

I have put the

However, if i specify the exact path of the file as follows, then it works:
System.setProperty("java.security.auth.login.config","d:/MyTestDir/myClient.jar/myConfig.conf");

I DO NOT want to specify the absolute path in my code. Is there any solution for this(apart from passing the file as an argument through command line during executing the program)?

Thank you

I do not believe that the default sun implementation is searching through the classpath to find the JAAS config file (see http://java.sun.com/j2se/1.4.2/docs/guide/security/jaas/spec/com/sun/security/auth/login/ConfigFile.html).

But you should be able to programmatically define your own JAAS configuration uising http://java.sun.com/j2se/1.4.2/docs/api/javax/security/auth/login/Configuration.html#setConfiguration(javax.security.auth.login.Configuration)

Hi Thomas,
Thanks for the links. Will try to implement my own Configuration.

Just out of curiosity, wanted to know, whether this is a common known problem. Has anyone faced this problem while running a standalone client and trying to do a JAAS login to access some ejb resource. If yes, is creating your own implementation of Configuration the only solution to this?

Would like to know whether there is any other solution

Thank you.

You can try to give the URL to the myConf.conf file if you include it in your jar:

final String authFile = "jar:file:myConf.jar!/com/mycompany/auth.conf"; System.setProperty("java.security.auth.login.config", authFile);

For some reason that does not seem to work for the unit tests under Maven... but it does work for Webstart and command line.

Hope this helps,

Benoit

Yes this is a pretty common thing to do when you first start off with JAAS. I did the same too. I use the -D argument to the java command as below

java -Djava.security.auth.login.config=conf/auth.conf <MAIN_CLASS>

This need to be under the current directory.

Hi,
Thanks a lot for the above suggestions. I tried out:

final String authFile = "jar:file:myConf.jar!/com/mycompany/auth.conf";
System.setProperty("java.security.auth.login.config", authFile);

and it worked. I have a constraint that i cannot accept the java.security.auth.login.conf as parameter from command line. So i did not go for the following approach:

java -Djava.security.auth.login.config=conf/auth.conf <MAIN_CLASS>

Thank you, both, for the suggestions

Dear Colleague

I am really pissed off with this security program in tahe top entry by mr Scott.

I have trying 3 weeks on it.

error after error.

finaly it compiles, deploys but again error

once the jndi is not specified ok now but the error in the login-conf and the same as yours but it seems mine so awkward.

Do mind if you KINDLY PASS me the program zipped with steps to run it.

I DO FEEL so appreciative really.

I will help you to pass you any program I do run.

thanks
