Hi,
I have some OSGI bundles that use different type of iText. I am trying to install these bundles via a plan into virgo. Now I get the message, that package imports cannot be merged:

Caused by: org.eclipse.virgo.kernel.osgi.framework.ImportMergeException: cannot merge imports of package 'com.lowagie.text.pdf.hyphenation' from sources 'Import
-Bundle 'com.portigon.server.csar-1-com.portigonsource.iText-1.3.4' version '1.3.4', Import-Bundle 'com.portigon.server.csar-1-com.portigonsource.iText-2.1.7' v
ersion '2.1.7'' because of conflicting values 'com.portigon.server.csar-1-com.portigonsource.iText-2.1.7', 'com.portigon.server.csar-1-com.portigonsource.iText-
1.3.4' of attribute 'bundle-symbolic-name'

I have had the same problem with some of my own bundles. The reason was that two bundles exported the same package name. Solved it by renaming the package in one bundle. I don't want to rename the iText pacakges and I am sure that one of the features of OSGI is that same bundles can be used in different versions. Can someone explain why this does not work with virgo? And why is virgo complaining about the symbolic name (you can see in the attached manifests that it is not the same):

Here is the manifest of the first bundle:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: iText 1.3.4
Bundle-SymbolicName: com.portigonsource.iText-1.3.4
Bundle-Version: 1.3.4

And here the other one:

Manifest-Version: 1.0

Bundle-Version: 2.1.7

 com.lowagie.text.xml.simpleparser;version="2.1.7",
 com.lowagie.text.xml.xmp;version="2.1.7",
 com.lowagie.tools;version="2.1.7"

Any hints on this?

Thorsten
