Re: [basedb-devel] External authentication
Sorry, just noticed that you mentioned the ...basedb.util.JarClassLoader, not a regular Java class loader as I initially thought.

Re: [basedb-devel] External authentication
Thanks for a quick reply. I really wanted to avoid selecting jars and so on since BASE has over 50 of them, and maven downloads over 60 for my plugin. Lots of manual work that needs to be done every time BASE is upgraded. I will try to change the Application class as you suggested. I have already located the place which needs a fix, but was unsure of playing so close to the core of the application. What about using the net.sf.basedb.util.JarClassLoader, as regular plugins do? I will post a patch when ready and tested.

I am not aware of any real case that uses external authentication so it would be very interesting to see if you succeed. It's quite common that there are dependencies to different versions of 3rd-party JAR files, but it usually works if the latest one is used. But of course, it may not work if the API has changed in an incompatible way. If you can't get it to work by clever selection of JAR files, then you might have to modify the Application.getAuthenticator() method so that it uses a different class loader. It shouldn't be too difficult. It could for example pick up a JAR path from the base.config file and then use the net.sf.basedb.util.JarClassLoader.getInstance(path) to create a class loader. Dependencies need to be listed in the MANIFEST.MF in the same way as for plug-ins.

[basedb-devel] External authentication
Hi, I am working on an external authentication plugin for BASE that will use an STS Web service to authenticate users. The plugin uses a bunch of external jars for WS communication, but with different versions then BASE. I was hoping for the same classloading mechanism as for regular plugins (separate classloaders), but it looks like external authentication plugins uses the default classloader of the webapp. Could this be changed? How else could I install my plugin, without messing with BASE's jars? Thanks, Pawel -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
