I'm trying to port: Apache Qpid Client, JMS and JNDI -- to Android. I'm able to get a successful compile/build of my QpidDroid project when running the ant debug install targets after passing Dalvik the --core-library parameter to allow javax packages for JMS/JNDI. I'm hoping to do this before considering repackaging/refactoring javax classes into a different package namespace using jarjar.
I think this is legally legit because I'm using the old/first seperate JNDI jar currently provided by Oracle's website. I'm using the JMS jar that comes with Apache Geronimo in Qpid,.. but I think it's also available from Oracle as a seperate download. My dev environment uses Android platform 2.1 and jdk 1.6.
The problem is, it seems it currently cannot instantiate my custom jndi connection factory: PropertiesFileInitialContextFactory. This is a .java source file in my QpidDroid project(not a .class in a libs jar) (I extracted the class out of the qpidClient jar).
Would someone have any idea as to why it cannot be instantiated here? I was wondering if proguard might be breaking reflection,... but I'm building it with the debug ant task,.. so I'm thinking proguard shouldn't be running at all. The exception occurs when I run the installed app on the emulator. I have the Apache Qpid service running on the same machine with the default port that it uses.

Thanks for any tips!
I think I found the problem -- Android has bugs in it with Reflection prior to version 2.3

I ported my QpidDroid project to Android 2.3 and it looks like JNDI is successfully creating the InitialContext now with the QPID connection params
