no security manage ?

[maouche]

Hello,

I need Help.

I am trying to execute an RMI client programm which uses UserTransaction. in jboss.jcml I have configured Tyrex transaction manager. (JBOSS2.4.4 with Tomcat 4.0.1 )


ut = (UserTransaction) ctx.lookup("UserTransaction"); //OK

ut.begin() // fail here with the following message error


javax.transaction.SystemException: java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
[java] java.lang.ClassNotFoundException: org.jboss.tm.plugins.tyrex.TyrexTxPropagationContext (no security manager: RMI class loader disabled)
[java] at org.jboss.tm.usertx.client.ClientUserTransaction.begin(ClientUserTransaction.java:106)
[java] at test.MyClient1.main(MyClient1.java:94)


Thanks

Have you tried configuring a SecurityManager
on the client?

This will allow any server classes to be downloaded
dynamically to the client.

How can You do it ?
I have just included in my classpath all the jar files in $JBOSS_DIST/client

[adrian.brock]

The tyrex plugins aren't in jboss-client.jar :-(

Have a look at java.rmi.RMISecurityManager
or sections 5.5 in the RMI Specification.

Alternatively, extract the tyrex plugin class(es)
from jboss/lib/ext/jboss.jar into a new jar in jboss/client.

Regards,
Adrian

I works better, But I have an exception when I commit the
transaction. This means that there are no transaction propagation. I will study more about java.rmi.RMISecurityManager in order to look for an other solution.

Thanks
