Have you ever tried printing something in History tab with a simple program and it worked at your end?

Hi Tapan

Yes, we have used the exact same calls in several programs without any issues

Looking at the stack trace, it seems to be related to some jar . Can you please check the log4j jar you are using in your URL app and see if it is compatible? Starting from RUP releases, Agile now provides the compatible version of 3rd party jars. Here is an example

https://updates.oracle.com/Orion/Services/download?type=readme&aru=23011979

This might give a clue

That is strange but anyways thanks for sharing the above info.

To be more specific in my case below is my code which is resulting in the exception. —————————————————————————————————-

public static void main(String args[])

try

{

// Creating agile session in variable ‘session’

IChange change = (IChange)session.getObject(IChange.OBJECT_TYPE, <Change_number>);

change.logAction(“This is test message”);

}

catch(Exception e)

e.printStackTrace()

}

—————————————————————————————————-

I am trying to print the message in History tab not with a URL PX but with a simple java program instead. I hope this is no different than a URL PX itself.

Any more comments?

That’s correct. It is no different in an URL PX except that the Session and Change object you are working on is provided to Agile automatically

Question – Are you able to do anything with the session? Like printing the user details of the session to a log. Or, is this is the first statement?  I am thinking that you have a problem getting even the session

I just ran the exact same piece of code again and it worked now. Not sure what magic happened..!!

I was on vacations for a week, so just touched the code today again.

Anyways, thanks a lot for your help.

Good that it worked. My guess is your SDK cache got cleared and that helped resolve the issue

Hi Karthik,   The AgileAPI.jar file is the same one residing on my app server. Have you tried printing something on history tab with a simple 2 liner sdk program and did that work for you?

Yes Tapan.

That works and updates History Tab.

Hi Tapan,

Are you getting the exception with standalone program as well (or) only in URL PX?

What is the version of Agile you are using?

Hi Karthik,

I just ran the exact same piece of code again and it worked now…!! This is very surprising for me. I was on vacations for a week, so just touched the code today.

Thanks a lot for your help.
