Hi Gokturk,
I had looked at the first URL when I was attempting to get my ancient
version of the Eclipse plugin to work. I had first attempted to follow
its directions, but I received an exception when attempting to manipulate
the bundle.
Here's what I got:
Buildfile: /Users/mcook008/Documents/workspace/MyiPOJOBundle/build.xml
manipulate:
[ipojo] Input directory :
/Users/mcook008/Documents/workspace/MyiPOJOBundle/bin
[ipojo] Metadata file :
/Users/mcook008/Documents/workspace/MyiPOJOBundle/metadata.xml
[ipojo] Start manipulation
BUILD FAILED
/Users/mcook008/Documents/workspace/MyiPOJOBundle/build.xml:54:
java.lang.ArrayIndexOutOfBoundsException: 8
On the second URL, it looks interesting, but there is insufficient
information on the page for someone without subject matter expertise to
understand how to configure it.
I have 15 years of Java programming experience, and I've been working with
OSGi for several years. I'm very comfortable building my own manifests
and developing (I think) good OSGi code. But there is a learning curve
associated with what I do, and I often work with others who don't have the
time to become expert in all things OSGi, so I was attempting to find out
if iPOJO might make it easier for me to teach them an easier way to
develop OSGi applications. So far, it unfortunately appears that there is
more difficulty in trying to simplify the development process than there
is in the development process itself.
I'm likely missing something trivial and obvious to those who work with
iPOJO regularly, and my poor Eclipse environment is likely hopelessly
misconfigured from my failed attempts at finding the correct combination
of libraries.
I think maybe I'll stick with the "old fashioned" OSGi way, unless there
is a decent tutorial available which I can follow and learn the "correct"
way to work with iPOJO. The funny thing is that a couple of years ago, I
had used Clement's old iPOJO plugin for a few projects, and it worked
easily. That's what made me decide to try it again, but I can't repeat
the good results of a couple of years ago...
Thanks for all of the help.
Mike
