I've also checked that the class file work/org.eclipse.virgo.kernel.deployer_2.1.1.RELEASE/staging/pshd.plan-3.2/bundle/pshd.plan-3.2-ru.focusmedia.poim-protocol/2.0.1/POIM_Protocol.jar/ru/focusmedia/odp/poim/protocol/AccessRights.class is actually there after ru.focusmedia.poim-protocol is started.

Please see the Virgo FAQ for class loading diagnostic ideas.

The problem is the format of the first MANIFEST.MF file. Most OSGi implementations expect each line of a MANIFEST.MF file to be no more than 80 characters, and when an entry in the MANIFEST.MF file spans multiple lines, it expects the first character of each line in the entry after the first line to have a leading space. In the past, I've experienced only the first line of an improperly formatted entry in a MANIFEST.MF file to be read, which can cause all kinds of wonky behaviour.

In addition to that, you are using the "import bundle" directive to import a package. This should be in the IMPORT-PACKAGE section.
