Comments on: Code Generate Custom SOAP Faults For Axis2/C

good to know the gen tool is supporting this scenario now.

I’m using Axis2Java 1.5.4 to compile my WSDL, the code generated doesn’t include the third parameter about the fault, some option for the compiler needed?

So,I had to use a ThreadLocal technique to simulate this feature. In the business logic section i added the custom error to the current thread, using the pthread lib, then i returned NULL (pretty the same as the example, replacing the AXIS2_ERROR_SET call with my own threadlocal utility).

Then, going back into the skel interface you have to override the on_fault callback like this:
axiom_node_t* AXIS2_CALL
axis2_svc_skel_SystemServicesService_on_fault(axis2_svc_skeleton_t *svc_skeleton,
const axutil_env_t *env, axiom_node_t *node) {

axiom_node_t * retNode = NULL;
retNode = CSTAErrorManager::getReference().getError();
//retNode = adb_ErrorValue_serialize(eValue, env, NULL, NULL, AXIS2_TRUE, NULL, NULL);
axiom_node_add_child (node, env, retNode);
return retNode;
}

hope this helps someone.

Hi,
You have to set AXIS2_ERROR_SET method with the error code and fault->your_excpetion_name with your exception object. In the tutorial it is shown in like this,
/* 1. Creating the adb object and set it to the fault pointer variable */
adb_MyFirstException_t *exp = NULL;
exp = adb_MyFirstException_create(env);
adb_MyFirstException_set_text(exp, env, “this is the exception 1″); /* custom value */

fault->MyFirstException = exp;

/* 2. Setting the error constant corrosponding to the fault */
AXIS2_ERROR_SET(env->error,
AXIS2_SKEL_MYSERVICE_MYOPERATION_FAULT_MYFIRSTEXCEPTION,
AXIS2_FAILURE);

/* 3. Returning NULL */
return NULL;

Got it?

Hi,
Can you trace and check the details element present in your soap message?

just to add to it,
I understand that to create a axis fault using axis2c i need to set the fault element using AXIS2_HANDLE_ERROR and just return NULL from business logic. I assume now, axis2c would create SOAP fault using the error message that the AXIS2_HANDLE_ERROR had set .

So it should pass the fault message to my java layer and Java layer has to recoginse it has axis fault and output the error message accordingly.
But what i see in tomcat logs are the following (which tells the axis2fault created by axis2c is lost and just NULL is returned.So how to I pass the fault information to Java side.

at org.apache.axis2.description.OutInAxisOperationClient.handleResponse(Ou tInAxisOperation.java:370)
at org.apache.axis2.description.OutInAxisOperationClient.send(OutInAxisOpe ration.java:416)
at org.apache.axis2.description.OutInAxisOperationClient.executeImpl(OutIn AxisOperation.java:228)

hi dimuthu
I need to pass the axis2c fault from C side to java side (tomcat).
Currently what i do is:
adb_test response =NULL;
AXIS2_HANDLE_ERROR(env,
AXIS2_ERROR_REPOS_BAD_SEARCH_TEXT,
AXIS2_FAILURE);

return response;

what i see at the end is : org.apache.axis2.AxisFault: Data element of the OM Node is NULL.

What i want is my error that i have set (AXIS2_ERROR_REPOS_BAD_SEARCH_TEXT) at the C level?

Hi,
As I remember people was working on Axis2/Java 1.5 release in a different branch. So most probably this will not be in that release. That mean you have to get it from source.
Thanks

Hi Dimuthu,

Many thx for your articles.
Very helpful when dealing with axis2c.
Is the fault exception handling available in axis2/Java 1.5.1 codegen or do I have to get it from the sources ?

Hi Dimuthu,

Great article. Been having to learn Axis2/C in a hurry and have found your writings on it quite useful. Just thought I would take a minute during rebuilds to tell ya that.

Hi,
You can check a test cases to the wsdl and generated files from this jira, https://issues.apache.org/jira/browse/AXIS2C-1344. Make sure your generated code is same as that.
Or probably there may be old jars in the classpath.

Thanks

Hi!

You wrote:

“Note that this feature is available only in the very latest WSDL2C tool. Try to get latest build from Axis2/Java to use this up to date tool.”

I checked out axis2 version 1.5, but i cannot create such code you explained above. Is it possible to write down step-by-step how did you generate the code and which version of WSDL2C was used?

Thanks your help, br,

robert.
