Thomas Diesler [http://community.jboss.org/people/thomas.diesler%40jboss.com] created the discussion "Cannot load package from deployment that has dynamic imports" To view the discussion, visit: http://community.jboss.org/message/541003#541003 -------------------------------------------------------------- The symptom is that we see WARN messages like this 09:04:13,595 WARN  [BaseDelegateLoader] Not getting package org.osgi.service.log from policy that has no classLoader: LazyFilteredDelegateLoader@a75737{factory=org.jboss.classloading.spi.dependency.policy.DynamicClassLoaderPolicyFactory(a)4f0853 filter=<EVERYTHING>} 09:04:13,599 WARN  [BaseDelegateLoader] Not getting package org.osgi.service.log from policy that has no classLoader: LazyFilteredDelegateLoader@a75737{factory=org.jboss.classloading.spi.dependency.policy.DynamicClassLoaderPolicyFactory(a)4f0853 filter=<EVERYTHING>} 09:04:13,727 WARN  [BaseDelegateLoader] Not getting package org.osgi.util.tracker from policy that has no classLoader: LazyFilteredDelegateLoader@a75737{factory=org.jboss.classloading.spi.dependency.policy.DynamicClassLoaderPolicyFactory(a)4f0853 filter=<EVERYTHING> The reason seems that the http://fisheye.jboss.org/browse/JBossAS/projects/jboss-cl/tags/2.2.0.Alph... BaseClassLoaderDomain uses this sematics in getPackage 1. // Try the before attempt 2. // Next we try the old "big ball of mud" model 3. // Next we try the imports   4. // Finally use any requesting classloader 5. // Try the after attempt In step #3 the imports also include the dynamic imports (even the EVERYTHING aka '*' imports) The  LazyFilteredDelegateLoader has no classloader associated and getPackage fails. In OSGi dynamic imports are considered *after* the bundles embedded classpath. I suggest we split getPackageFromImports in two variants and consider dynamic import between step #4 and #5 -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/541003#541003] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
