This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I'm a little confused by a difference I've run into between unpacked files and .aar archives deployed in Axis2 on Tomcat.
I went through a tutorial on database web services where you implement theServiceLifeCycle to establish and/or close a database connection at the time the service is loaded. (Here's the link to the tutorial if you're interested, though it's probably not necessary to follow this post...)
I wanted to use the service archiver wizard plugin for eclipse, so I used it to generate the .aar file. Then I unzipped it (by renaming the extension from .aar to .zip) and editied services.xml in the WEB-INF directory to make sure the class that implements servcelifecycle is referenced and loaded when the service launches.
So far, so good. The application worked. However, when I zipped the file and renamed it to .aar (which I think is legit - a .aar, as far as I understand, is just an archive of the .class files and some configuration files), the directory that worked when unpacked threw and exception - "services.xml" not found.
Is a different mechanism invoked when Axis2 encounters a .aar file instead of an unpacked file? It's exactly the same directory, just zipped with a .aar extension.
Oh, in case it helps - if I do this but *don't* alter the services.xml file, this error doesn't occur (however, in that case, I wouldn't be able to configure the ServiceLifCycle implementation class.
