Re: [axis2] use spring configured bean inside axis2 as implementation class
Hi Anderson,Thanks for the feedback and I definitely appreciate it.Once you are free please try out the fix by Dims to the class loading issue.I guess that will take care of the main concern you have. Also you don't have to expose your spring beans (the ones that implement the business logic) directly to leverage the spring support.also please see my comments inline.

[RA] You don't have to expose your spring beans (the ones that implement the business logic) directly to leverage the spring support.You could still have the WebService that calls your core spring beans (which implements the business logic) as Spring beans. So you are not directly exposing your business logic, but still you are using spring to wire your web service with the spring beans that implement the business logic. For examplepublic class MyWebService { private MyGreeting myGreeting; // let spring inject the dependency public void setMyGreeting(myGreeting){ this.myGreeting = myGreeting; } public String greet(String name){ return myGreeting.greetAccordingToTheTimeOfDay(name); }}//your business logicpublic class MyGreetingImpl implements MyGreeting{ public String greetAccordingToTheTimeOfDay(String name){ // if morning return "Good morning " + name: } public String greetWithLove(String name){ // . }} My main issues with using Axis2 and Spring revolved around the Service classloader. Spring likes to use the context classloader which does not have access to the resources deployed with the service. I tried setting the classloader for Spring (one can set the classloader for the application context and the bean loader) but I ran into some problems with setting properties on Spring beans that I chalked up to permissions issues. My current workaround is ugly but it works. I deploy the Spring jars and the core services jar in the WEB-INF/lib for Axis2. My service AAR just contains the Web Service skeletons. I do want to try the latest build. The changes in the Service classloader look promising. Unfortunately I am going on vacation for a few days after today. I am also trying to do a QA drop before I go so I am quite busy today. That means I can't try the nightly build until late next week. I would really like to not have to mess with the axis2.war so I am eager to try it out. Thanks for the quick response on the issue though.

RE: [axis2] use spring configured bean inside axis2 as implementation class
Hi Rajith, Here is how I am putting my application together. I have a set of core services that are Spring beans. I use Hibernate as my persistence tier.
