Subject My Android QPID port progress, PropertiesFileInitialContextFactory question
Date Thu, 19 Jan 2012 21:54:47 GMT

Hi QPID folks,

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!
