Description

« Hide

I would like to contribute the attached code which is as Servlet similar to the XFireStandaloneServlet from xfire-plexus. We had problems inside Oracle ias 9.0.4 with the classloader stuff. The Servlet replace all plexus stuff incl. classworlds and need the services.xml inside the classpath e.g. Web-Inf/classes. It need jdom 1.0 and his dependend jars as xml parsing engine. I hadn't had the time to dig deeper into the problem but the effects was NoClassDefFound errors in places which didn't make sense. The problem was classworlds because without that jar we didn't get this errors in our code.

Very cool Ralf. This is something I'd been meaning to do for a while. I'm not so sure about using JDOM to parse the xml though as that will add another dependency. We could use YOM instead (our MIT licensed XOM clone - see http://xom.nu for javadocs). I think it would be very good to get this in before M5 though! It would relieve some confusion too over plexus.

Thanks Ralf. I'll be taking a look at this later this week I think.

Just a comment or two on this while I'm looking at it:
1. There isn't a way to specify the implementation class
2. Its not possible to specify a different ServiceFactory. Granted I don't know a good way to do this though...

Other than that it looks good

Just wanted you to know that I'm working on this right now (hopefully I can finish it before my phone starts ringing off the hook again). The reason it is taking a little bit is because there are some differences in HEAD compared to the version you wrote it against.

Dan,

could you please change the impl from

private final static String CONFIG_FILE = "META-INF/xfire/services.xml";

private final static String CONFIG_FILE = "services.xml";

The most of configurable java apis like log4j search for a file in the
classpath. In web development are that kind of files in the Web-Inf/classes folder.
I would really appreaciate to have the xfire file in the same place.

Ralf, it searches for that file on the classpath, not on the file system. So it would go in WEB-INF/classes/META-INF/xfire/services.xml. It just in a different location on the classpath... is that alright?

Dan, i saw the way it works and thought IMHO it would be more common if the file is not in a subfolder of the classpath.
