Hey, I manipulated my bundle using Ipojo Ant Task, as the following:
<project>
<target name="main">
<!-- Change the path to point on the iPOJO Ant task jar-->
<taskdef name="ipojo"
classname="org.apache.felix.ipojo.task.IPojoTask"
classpath="C:/Users/zaid.almahmoud/Dropbox/EBTIC/ADERE/feasibility-codes/ipojo/ipojo-distribution-1.11.0/bundle/org.apache.felix.ipojo.ant-1.11.0.jar"/>
<ipojo
input="C:/Users/zaid.almahmoud/Desktop/plugins/HelloService_1.0.0.201401222235.jar"
output="C:/Users/zaid.almahmoud/Desktop/plugins/Manipulated_HelloService.jar"
/>
</target>
</project>
Now, I can see in my app that the factory is valid. This is the output in the
command:
g! ipojo:factories
Factory my-factory (VALID)
Factory org.apache.felix.ipojo.arch.gogo.Arch (UNKNOWN) - Private
Therefore the factory "my-factory" is available unlike before.
However, my instance is not available, which was created as the following:
DefaultInstanceDeclaration providerDeclaration = new
DefaultInstanceDeclaration(b.getBundleContext(), "my-factory");
providerDeclaration.start();
Again, this does not show an error, but it doesn't display the expected output
in the start() method of the bundle, and on the command, I can see:
g! ipojo:instance my-factory-0
Instance named 'my-factory-0' not found
Can you help please? Thanks.

It displays this:
ipojo:factories
Factory org.apache.felix.ipojo.arch.gogo.Arch (UNKNOWN) - Private
I am not sure what you mean by iPOJO manipulation on my bundles,
But again, I am not using ANT or MAVEN. I export the bundles normally in
eclipse (Using export->deployable plugins and fragments).
Could it be the issue?

Hi,
The output are interesting, it looks like your instances are not declared
correctly. Can you try:
> ipojo:factories
By the way, how are you applying the iPOJO manipulation on your bundles ?
Regards,
Clement
