[jira] Created: (FELIX-2497) Jython support in iPOJO API
Jython support in iPOJO API
---------------------------
Key: FELIX-2497
URL: https://issues.apache.org/jira/browse/FELIX-2497
Project: Felix
Issue Type: Wish
Components: iPOJO
Reporter: YANG, BongYeol
Priority: Minor
I tried to build iPOJO component dynamically using jython script and iPOJO api, but I can't. Because iPOJO cannot find dynamically added python proxy classes like this:
----
>>> sys.add_package('org.apache.felix.ipojo.api')
<java package org.apache.felix.ipojo.api 0x2>
>>> from org.apache.felix.ipojo.api import PrimitiveComponentType
>>> PrimitiveComponentType
<type 'org.apache.felix.ipojo.api.PrimitiveComponentType'>
>>> from java.lang import *
>>> Runnable
<type 'java.lang.Runnable'>
>>> class Test(Runnable):
... def run():
... print 'Hello'
...
>>> Test().getClass().getName()
u'org.python.proxies.__main__$Test$0'
>>> c = PrimitiveComponentType().setBundleContext(bc).setClassName(u'org.python.proxies.__main__$Test$0').createInstance()
Traceback (most recent call last):

----
How about creating overloaded setClassName() method on API? for example, setClass(Class<?>) or any idea..?

[jira] Commented: (FELIX-2497) Jython support in iPOJO API
Posted by "Clement Escoffier (JIRA)" <ji...@apache.org>.

Clement Escoffier commented on FELIX-2497:
------------------------------------------
Hi,
It's a little bit more tricky. iPOJO requires the byte array to manipulate the class. So a setClass(Class) will not help, but a setClass(byte[]) can do the job. However, do you have the possibility to get the byte array of the class ?

YANG, BongYeol closed FELIX-2497.
---------------------------------
Resolution: Fixed
i couldn't find how to get jython-generated bytecode. I will try it later.
