[jira] Commented: (AXIS2C-330) Null pointer read while parsing WSDL
[ http://issues.apache.org/jira/browse/AXIS2C-330?page=comments#action_12449271 ]
Damitha Kumarage commented on AXIS2C-330:
-----------------------------------------
I tested with the attached googlesearch.wsdl after fixing a bug in XmlSchema. test_wsdl1 sample works.
Please send your googlesearch.wsdl if it is differnt.
> Null pointer read while parsing WSDL
> ------------------------------------
>
> Key: AXIS2C-330
> URL: http://issues.apache.org/jira/browse/AXIS2C-330
> Project: Axis2-C
> Issue Type: Bug
> Components: woden
> Affects Versions: Current (Nightly)
> Environment: Windows XP
> Reporter: Jose M. Sánchez
>
> While parsing a WSDL file my program crashes because of reading a null pointer.
> While debugging I have found the following situation:
> file: /c/woden/src/wsdl/documentable.c
> I see that:
> documentable_impl_l = NULL
> woden_documentable_resolve_methods(
> woden_documentable_t *documentable,
> const axis2_env_t *env,
> woden_documentable_t *documentable_impl,
> axis2_hash_t *methods)
> {
> [...]
> documentable->ops->add_documentation_element = axis2_hash_get(methods, <-- after this, add_documentation_element = NULL
> "add_documentation_element", AXIS2_HASH_KEY_STRING);
> if (!documentable->ops->add_documentation_element && documentable_impl_l) <-- it does not enter here
> documentable->ops->add_documentation_element =
> documentable_impl_l->documentable.ops->add_documentation_element;
> [...]
> }
> after the execution of this function, the operation add_documentation_element = NULL, then in the following function it fails:
> file: /c/woden/src/builder/wsdl10_reader.c
> static void *
> parse_interface_op(
> void *reader,
> const axis2_env_t *env,
> axiom_node_t *op_el_node,
> void *desc,
> void *parent)
> {
> [...]
> if (AXIS2_TRUE == axis2_qname_util_matches(env,
> q_elem_documentation, temp_el_node))
> {
> void *documentation = NULL;
> documentation = parse_documentation(reader, env, temp_el_node, desc);
> op = woden_interface_op_to_documentable(op, env);
> WODEN_DOCUMENTABLE_ADD_DOCUMENTATION_ELEMENT(op, env, documentation); <-- Fails here
> }
> [...]
> }
> The call to WODEN_DOCUMENTABLE_ADD_DOCUMENTATION_ELEMENT fails, because the method add_documentation_element is null.
> I have tested this with my own code, as well as with the test_woden sample program (which is very similar to my code), using different wsdl files, for example the googlesearch.wsdl file, and the result was always the same.
