Re: AXIS2 - Application Service Scope Questions
Tbanks Deepal for your informative response. Now I feel confident on how to write my 'application' scoped web service (ie, taking care to be threadsafe).

Once you deploy a service in application scope we create only one instance of the service implementation class. And we store the instance in the ServiceContext. So each and every request coming to that service uses the same service instance. However in web service world we have to write our services in a stateless manner , meaning write the class so that we do not store any class level variable in the service impl class. Then the service invocation would become thread safe as well. Thank you!

AXIS2 - Application Service Scope Questions
I have a couple of questions regarding Axis2 web services configured to run with service scope set to 'Application': 1) Is the web service a singleton? 2) Is the web service thread-safe? I think that the answers are 1) Yes, 2) No. I couldn't find an explicit answer in the Axis2 documentation.

AXIS2 -Ewdc option for wsdl2java using xmlbeans databinding
I downloaded the axis2 nightly build in order to try the -Ewdc wsdl2java
option.
When I run the wsdl2java for the StockQuotePrice quicksample and use the
-Ewdc option for xmlbeans binding, I get the following errors:

I don't get any errors, when I remove the -Ewdc option. Do you know
what's wrong?

Re: AXIS2 wsdl2java limitations using jibx and xmlbeans databinding
Thanks Amila for pointing out the missing 'parts' attribute in the
soap:body of my wsdl:binding.
7 out of 9 of my tests are now working. Here are my results thus far
using wsdl2java for ADB, JIBX, XMLBeans data bindings:
ADB Binding: All my test cases are working for ADB.
XMLBeans Binding: still have a problem with circular imports.
--
Amila, I don't quite understand how to proceed. What is the -Ewdc
option? I tried the -Ewdc wsdl2java option using the same import
declaration for the xmlschema that causes circular references, and got
the same error for circular imports (Duplicate global type). There were
no classes, under the build/service/classes directory due to the error.
I've compiled the xmlschemas via scomp, but am not sure on how to proceed.
Results:
java.lang.RuntimeException: org.apache.xmlbeans.XmlException:
project://local/StockQuoteA.xsd:17:5: error: sch-props-correct.2:
Duplicate global type: [EMAIL PROTECTED]
(Original global type found in file: null)
JIBX Binding: still have problem with the 2 part message declartion
(which works with ADB binding)

Test Case 1: soap header declaration, using a wsdl:part element from
a wsdl:message element that contains 2 wsdl:part elements.

StockQuoteService wsdl provided in the quickstartjibx and

1) Test Results for more than one part element per message

This is because of the problem I mentioned earlier.
2) Test Results for Cirular imports in a wsdl, where xml schema A
imports schema B, which imports the original schema A:
-jibx: didn't try. xml schema is complicated.
-xmlbeans: Get 'Duplicate global element' Error.

Try this.
When generating the code with wsdl2java tool use -Ewdc option. This
would generate some dummy classes for Xml beans.
Then generate the Xmlbeans classes with the scomp tool comes with the
Xmlbeans distribution.
Then replace the above dummy classes with the latter generated data
bind classes.
3) Test Results for soap headers added to binding.
-jibx: Get mapping error when soap:header ... is added to binding.
