======
* Support for exposing Spring services through the IOC container
* Support for editing Axis 2 booting configuration through the IOC
container
* Automated WSDL generation of Spring services
* Support for querying service's WSDL (with ?wsdl), schema (with ?xsd) and
policies (with ?policy)
* Deployment of Axis2 Modules (WS-Addressing, WS-Security, etc.) through
the classpath
* Method exclusion in Spring beans

Apache Synapse / WSO2 ESB Community Site (beta)

WSO2 announced the launch of the Apache Synapse and the WSO2 ESB user community site - http://esbsite.org!

==================================================================
We hope that this will help us build a vibrant community around our users and developers, and help our community to share their experiences, extensions, articles, case studies, screen casts, patches and many more artifacts and resources related to these open source ESB's.

You can sign up as a member, and begin to upload your custom extensions, or article and code snippets etc, and rate content uploaded by fellow users. In the future, the Synpase developer community would also publish some of the extensions over the community site, which will allow users to update their installations with new functionality. The community site will also feature patches for released versions of the ESB's as well as link to articles and screen casts and FAQ's of interest.

Java2WSDL generation with custom schema - Axis2

Today I implemented a way to provide a custom schema when you generate WSDL from a Java class. In order to give a custom schema file you need to use the option

  • csl “location of the schema file”

In addition to that you can feed the mapping file to use your custom schema , then you have to give the full qualified class name and the schema Qname you can feed the mapping file using following option.

  • mfl – “Location of the mapping file”

Structure of the mapping file look like below;


org.foo.bar.FooException|http://www.ebay.com/soaframework/common/types|ErrorMessage

[You can have any number of above entries]


Then if your class is something like below;


package org.foo;

import org.foo.bar.FooException;


public class MyClass {

public String doFoo(String foo) throws FooException {

return foo;

}

}


Will generate the correct WSDL file using the mapping file as well as using the custom schema.
