Connection Interrupted when opening a Communication Channel

Former Member

Dear all

We have suddenly experienced problems after starting the Integration Directory.

When trying to edit one of the Communication Channels, a dialogue box appears saying:

Connection Interrupted

You can log on again once the server is available again

Do you want to log on again?

Password:

After entering the password, a new box appears saying: Reconnection to server was successful. Repeat the action

But the info about the communication channel is still not showing, and the same error message appears when trying to edit the Communication Channel again (going into a loop)

When debugging with Java Web Start the following error occurs:

#91 09:57:13 [AWT-EventQueue-0] DEBUG com.sap.aii.utilxi.swing.framework.cmd.OpenCommand: Open 'Communication Channel  | HRDCLNT270 | SenderABAPProxy (DirContext)'

Does anyone have a solution to this problem? We could edit the Communication Channel earlier so it seems like the problem have occured during the last week.

Regards

DID your VPN connection to the server has been terminated , once again relogin

The dialogue box is appearing no matter what communication channel I try to edit.

I've also tried a full cache refresh without any luck.

I have no VPN connection, I'm sitting on the same LAN as the server and have full access to it.

The server seems to function normally in all other aspects.

Hi,

When trying to edit one of the Communication Channels, a dialogue box appears saying:

Connection Interrupted

You can log on again once the server is available again

Do you want to log on again?

Password:

After entering the password, a new box appears saying: Reconnection to server was successful

This screen comes when Xi server is not up and running and after it is up if u try to do any changes then it will ask to enter the password

again.

Can you please close the IR and again login with the integration builder screen.

Thnx

Hi Chirag

I've tried what you've suggested but the error messages does still appear when trying to edit the Communication Channel after exiting and starting the integration builder.

The error that concerns me is:

com.sap.engine.services.rmi_p4.P4RuntimeException: Unexpected exception.Nested exception is:

java.io.InvalidClassException: com.sap.aii.ibdir.bom.cpa.Channel; local class incompatible: stream classdesc serialVersionUID = 366016170231986765, local class serialVersionUID = 2790972994638010697

java.io.InvalidClassException: com.sap.aii.ibdir.bom.cpa.Channel; local class incompatible: stream classdesc serialVersionUID = 366016170231986765, local class serialVersionUID = 2790972994638010697

java.io.InvalidClassException: com.sap.aii.ibdir.bom.cpa.Channel; local class incompatible: stream classdesc serialVersionUID = 366016170231986765, local class serialVersionUID = 2790972994638010697

It seems like the class com.sap.aii.ibdir.bom.cpa.Channel has a different UID locally and in the stream...
