Loading different versions of bundle in Spring OSGi

Hi all,

This is my first post in this forum.
U people are doing great. This forum is my usual stop for my queries.

My problem is similar post
http://forum.springsource.org/showthread.php?t=64480

I have 3 bundles
A,B,C

Bundle C has two versions say 1.0.0 and 1.1.0

Bundle dependency is as follows:
A-> B-> C1.0.0
A->C1.1.0

All bundles started for me without any problem

As mentioned one of my class in Bundle A is refering to some service in Bundle C of version 1.1.0 and B refering to C1.0.0
But when i run the application both bundle A and B is using same version 1.1.0. But both C1.0.0 and C1.1.0 is active.

Even i tried the samples given by dewanto. Both Solution and Pricing bundle using Udm 1.1.0, even though other version of Udm bundle is active. I wonder whether this worked for dewanto?

As per my understanding it should refer to services of corresponding versions.

Pls help me to solve this. :( very urgent!!

What versions have you specified in bundle A's manifest for its dependencies that are satisfied by bundle C? You can force bundle A to depend on version 1.1.0 of bundle C by using appropriate versions. For example if your two C bundles have the following manifests:

Code:

---

Bundle-SymbolicName: c
Bundle-Version: 1.0.0
Export-Package: c;version="1.0.0"

---

Code:

---

Bundle-SymbolicName: c
Bundle-Version: 1.1.0
Export-Package: c;version="1.1.0"

---

You can force Bundle A to depend upon Bundle C 1.1.0 by versioning its import of package c:

Code:

---

Bundle-SymbolicName: a
Bundle-Version: 1.0
Import-Package: c;version="[1.1.0,2.0)"

---

I've used a version range here that means it needs to import c at a version between 1.1.0 inclusive and 2.0 exclusive.

by mentioning the version like below worked.
version="[1.1.0,1.1.0]"

Thanks Andy
