Subject Re: Axis2C Soap Exception Handling
Date Wed, 04 Apr 2012 21:18:11 GMT
Hello everyone.

A good while ago I realized that the (then) current label of Axis2C
had a problem returning all fields of a soap exception thrown by the
remote server. I looked into it for a while and entered JIRA
AXIS2C-1507 for this.

As I noticed that over the last few months there had been numerous
patches and fixes applied to the trunk of Axis2C I tried latest Trunk
code against an asp.net soap service returning soap faults.
Unfortunately, the issue with not populating all fault members
apparently has not been fixed yet as current code behaves exactly the
same way in regards to this functionality.

Has anyone come up with a workaround for this issue or am I the only
one having problems with this and having a need for soap fault
support?

Thanks in advance,
Thomas
