Cannot export Web Application to WSO2 Application

I downloaded the latest version of WSO2 Developer Studio:

developer-studio-eclipse-jee-helios-linux-gtk-x86_64-2.1.0.zip

and the WSO2 Carbon 4 based Application Server version:

wso2as-5.0.1.zip

unzipped both and started Developer Studio. As I want to deploy a Maven webapp project, I installed m2e on top of WSO2 Developer Studio.

Then I followed this article:

http://wso2.org/library/articles/2012/09/develop-deploy-web-applications-using-wso2-developer-studio#section3

apart from the fact that the WSO2 Carbon and WSO2 AS versions are different and that I already have a maven war project which is imported into my workspace.

After creating a distribution project for my web app project, I add the webapp project to it. Afterwards I add that distribution project to the Carbon Server (wit 'Add/Remove').

The WSO2 Carbon server is started, but then a message is shown 'Can't find export handler for war'.

We repeated the steps several times, sometimes this stack trace appears on the console:

What is the correct way of deploying a mavenized web app to the WSO2 Carbon Application Server from WSO2 Developer Studio?

Thanks

回答1:

Can you paste the content of the Eclipse error log here for more inspection? Though it says it cannot find the Handler for WebApp, i suspect the real error is something else.

You can find the Eclipse Error log at /.metadata/.log file.

Regarding the correct way to deploy a Web-App to WSO2AS from WSO2 Developer Stidio, this article you referred explains the correct approach.

回答2:

Maybe m2e on top of WSO2 Developer Studio is the problem. As I can deploy WARs into WSO2AS without running into any exception, but I don't have installed m2e in my WSO2 Developer Studio.

Have you compared your existing POM with the POM generated for a webproject by the WSO2 Developer Studio?
