All,

Two dependencies are complaining. I am using JDK6. A quick peek at the manifests in the dependencies show they require JDK4 as a minimum.

If JDK4 is the minimum version required why the error over JDK6?

I pulled these two bundles from eclipse/plugins.

A bundle could not be resolved because the required execution enviroment did not match the runtime environment. In bundle <o
rg.apache.xerces_2.9.0.v201101211617>
        A bundle could not be resolved because the required execution enviroment did not match the runtime environment. In bundle <o
rg.apache.xml.serializer_2.7.1.v201005080400>

The xerces bundle you mention contains the following in its manifest:

Bundle-RequiredExecutionEnvironment: J2SE-1.2

and not J2SE-1.4. Please double-check the manifest.

Virgo's profile (lib/java6-server.profile) defines the following execution environments:

org.osgi.framework.executionenvironment = \
OSGi/Minimum-1.0,\
OSGi/Minimum-1.1,\
J2SE-1.3,\
J2SE-1.4,\
J2SE-1.5,\
JavaSE-1.6

There is no assumption that J2SE-1.4 covers J2SE-1.2, which is why you get a resolution error. If you want to make that assumption, add J2SE-1.2 to the above property.

Thanks again, clearly I misread the manifest in question. The real help was learning about the java6-server.profile file. I made the entry you recommended and that problem ceased.

Now I have another problem. What is hapi.plan-1-synthetic.context. It appears to have something to do with gemini's attempt to deploy my plan, which is called hapi.plan.

I don't understand how to interpret the following error.

Uses constraints are described in the FAQ. The synthetic context bundle is described in the Programmer Guide - search for "synthetic".

Uses constraint failures in resolving the synthetic context bundle are pretty rare - I don't remember seeing one before. So presumably you have transitive dependencies on multiple versions of the same package. The FAQ will give you some ideas for how to diagnose this.
