WARNING: Skipping entry because it is not an absolute URI. GlassFish in NetBeans

Question

I successfully installed GlassFish. However, when I start a server, I get this two warning messages:

WARNING: Skipping entry because it is not an absolute URI.

What is that about ?

Launching GlassFish on Felix platform

Answer 1

unwichtich is right that the warning can be ignored but you can also get rid of it.

To get rid of the warning edit the file <glassfish_home>/glassfish/config/osgi.properties and change the core.bundles property from:

core.bundles=\
    ${com.sun.aas.installRootURI}modules/endorsed/ \
    ${obr.bundles} \
    ${hk2.bundles} \
    ${com.sun.aas.installRootURI}modules/glassfish.jar

to:

core.bundles=\
    ${com.sun.aas.installRootURI}modules/endorsed/ \
    ${hk2.bundles} \
    ${com.sun.aas.installRootURI}modules/glassfish.jar

The warning is happening because BundleProvisioner reads a property in osgi.properties named glassfish.osgi.auto.start and it in turn references other properties like core.bundles.

The property that was removed above, obr.bundles, is currently commented out. The comment is expanded to a space which BundleProvisioner reads and issues a warning about.

Answer 2

You can safely ignore this warning.

It comes from com.sun.enterprise.glassfish.bootstrap.osgi.BundleProvisioner. This part of GlassFish installs/registers the GlassFish modules from the modules folder. It loops through a list of URIs, i.e. the file paths of the modules.

If an URI is not absolute, i.e. it is relative or it has no scheme component, then this class logs this warning. In this case the URIs are not absolute because GlassFish probably uses the paths relative from the GlassFish root.
