[Saravanakumar Jeyavel]

Hello ,

i am using jnlp to launch my application. recently updated to java 7. it was working fine, but since updated to java 7 i am getting the error javax.security.auth.login.LoginException: No LoginModules configured webutc though all the jars are being signed correctly. Below is my jnlp file

<?xml version="1.0" encoding="UTF-8"?>
<jnlp codebase="http://localhost:8380/webstart/proj/JNLP-INF/" href="APPLICATION.JNLP">
	<information>
		<title>Client</title>

	</security>
<resources>
<property name="java.security.auth.login.config" value="jar:http://localhost:8380/webstart/proj/auth.conf"/>

		<jar href="kunststoff.jar"/>						
		
	</resources>	

	<application-desc main-class="com.gfi.proj.client.main.Application"/>
</jnlp>

I am using jboss 7 and the login.config.xml contains the webutc info as below.

<application-policy name="webutc">
	<authentication>
	<login-module code="com.proj.loginmodule.LoginModule" flag="required">
		<module-option name="dsJndiName"/>
		<module-option name="rolesQuery"/>
		<module-option name="LDAPSearchProperties">
			LDAPSearch.properties
		</module-option>
	</login-module>
	</authentication>
    </application-policy>

Did you solve the problem?

I found this bug that seems related with the problem. It has a workaround, but I did not understand where I must put the code. Can anyone help?

Welcome to Ranch!

I believe that the initPreLoader fix actually needs to be applied to JDK sources, so this isn't a workaround. However, the quickAndDirtyFixForProblemWithWebStartInJava7u25 method seems promising, I'd try to call it at the beginning of the main method of the program. But I'm just guessing.
