webservice:problem in security during implementation of client program for wsag4j server

I am trying to create a service level agreement based grid scheduling. For that I am using wsag4j application server.
I am using tomcat 5.3.35 as my container and Eclipse SDK 3.5.2 as client API. My deployed web services is running perfactly. But when I am trying to run a client program.
I got following problem

I can't understand any thing. Can anyone help me please?.

It appears like the expiration date of the security certificate has passed without it being renewed. Certificates are only valid for a certain time, and you must renew them near the end of that time.

Thanks for your reply......Rob

How will I renew certificate?

I got a related post from http://packcs-e0.scai.fraunhofer.de/wsag4j/faq.html#security_header (because I am following guide http://packcs-e0.scai.fraunhofer.de/wsag4j/client/client-setup.html to set my client )

It says like that

Why do I get the error "security processing failed"?

WSAG4J uses WS-Security time stamps to ensure a message must be delivered within a certain time frame. If the clocks of a client system and a server system are not synchronous (e.g. the time differs more than 5 minutes) the security processing will fail.

But I can't understand how to synchronize client and server system.

my catalina.out shows the following......

is it actually synchronization problem as told..

please help me...........

Hi,
I've had the same problem as you, it was due to Certificate being expired on their framework. WSAG4J have now released a new version 1.0.2 so you should update yours and that will solve it.
Hopefully, you've already solved it by now.
Regards,
Dmitrijs.

Thank you for your reply............

I did that already...........

from: http://packcs-e0.scai.fraunhofer.de/wsag4j/client/client-setup.html

Add the WSAG4J configuration files. Create a new folder resources in your Java project. Copy all files from the classes folder of the WSAG4J client distribution to the resources folder. Right click the Java project and select Properties. Select Java Build Path->Libraries. Click Add Class Folder..., then select the resources folder and click OK.

You have to re-add these files (from the mentioned version 1.0.2) to update your wsag4j-client-keystore.jks file in your implementation.

Thank you for your reply............
I did that long days back....
It works perfectly fine now......
