Summary: Problem installing feature with fragment bundle for existing host bundle Key: KARAF-7779 URL: https://issues.apache.org/jira/browse/KARAF-7779 Project: Karaf Issue Type: Bug Components: karaf Affects Versions: 4.4.4 Reporter: Grzegorz Grzybek Assignee: Grzegorz Grzybek Fix For: 4.4.5 In my custom Karaf distro with custom KAR which uses Pax Web and fragment bundles (for javax-el-api), I had this problem: {noformat} java.lang.IllegalStateException: Resource has no uri at org.apache.karaf.features.internal.service.Deployer.getBundleInputStream(Deployer.java:1631) at org.apache.karaf.features.internal.service.Deployer.deploy(Deployer.java:904) ... {noformat} After quite complex investigation I was able to prepare a Karaf test case and the problem can be described like this: * we install a feature which contains fragment bundle which can be attached to already existing bundle * Karaf resolver/deployer treats already installed bundles as BundleRevisions (without {{osgi.content}} namespaced capabilities. {{url}} is part of Bundle capabilities only * during resolver procedure, I had this: {noformat} {org.apache.felix.framework.BundleRevisionImpl@7703} "org.apache.servicemix.specs.javax-el-api-3.0.0 [39](R 39.0)" -> {java.util.ArrayList@11407} size = 3 key: org.apache.felix.framework.BundleRevisionImpl = {org.apache.felix.framework.BundleRevisionImpl@7703} "org.apache.servicemix.specs.javax-el-api-3.0.0 [39](R 39.0)" value: java.util.ArrayList = {java.util.ArrayList@11407} size = 3 0 = {org.apache.felix.resolver.WireImpl@11791} "[org.apache.servicemix.specs.javax-el-api-3.0.0 [39](R 39.0)] osgi.wiring.package; (&(osgi.wiring.package=org.osgi.framework)(version>=1.6.0)(!(version>=2.0.0))) -> [org.apache.felix.framework [0](R 0)]" 1 = {org.apache.felix.resolver.WireImpl@11792} "[org.apache.servicemix.specs.javax-el-api-3.0.0 [39](R 39.0)] osgi.ee; (&(osgi.ee=JavaSE)(version=1.7)) -> [org.apache.felix.framework [0](R 0)]" 2 = {org.apache.felix.resolver.WireImpl@9972} "[org.jboss.fuse.modules.fuse-el2-compatibility/7.12.1.fuse-7_12_1-00009-redhat-00001] osgi.identity; osgi.identity="root#pax-web-jsp-8.0.23"; type=karaf.subsystem; version="[0,0.0.0]"; resolution:=mandatory -> [root#pax-web-jsp-8.0.23]" {noformat} which means that the fragment added a wire to the host bundle. The wire ties the BundleRevision resource to feature's subsystem, effectively marking already existing BundleRevision as a resource to install. The problem is that there's no {{osgi.content; url=xxx}} capability inside existing BundleRevision. -- This message was sent by Atlassian Jira (v8.20.10#820010)
