Proxy error - HTTP status code 500

Hi,

Scenario: Asynchronous Proxy (R/3 4.7) to 3rd Party (JDBC)

We applied patches to JAVA on the XI side to fix a bug, the process worked before the patches. I am now getting an error on R/3 i.e. the data is not reaching XI.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<SAP:Text language="EN">HTTP status code 500 : Error during conversion of XI message</SAP:Text>

</SAP:ErrorHeader>

Any ideas. Thanks,

Leanne
