"Problems with Spring resource loading in an OSGi bundle" To view the discussion, visit: http://community.jboss.org/message/632884#632884 -------------------------------------------------------------- I have a large Spring application that I am trying to convert to a single OSGi bundle for deployment into JBoss (AS 7.0.2). Initially I am trying to minimize code changes and deploy the application as-is, but I am running into issues with Spring resource loading. I've created a relatively simple application as a reproducer. The application is an OSGi bundle with a few simple Spring beans using ClassPathXmlApplicationContext. I am building the bundle with maven-bundle-plugin and embeding transitive dependencies including Spring 3.0.6 JARs. When I use a simple configuration location such as "classpath:spring/applicationContext.xml" everything works fine. However, the real application has several different locations using combinations of "classpath*:" and location patterns such as "classpath:spring/*Context.xml". These locations with patterns are causing problems. Despite Spring's support for VFS it is not being used in these cases. Within the OSGi context Spring is getting resource URLs with a "bundle:" protocol and doesn't know what to do with them. So it falls back to assuming they are files, and the resource loading fails: 22:05:18,264 WARN [org.springframework.core.io.support.PathMatchingResourcePatternResolver] (MSC service thread 1-4) Cannot search for matching files underneath class path resource [spring/] because it does not correspond to a directory in the file system: java.io.FileNotFoundException: class path resource [spring/] cannot be resolved to absolute file path because it does not reside in the file system: bundle://com.tendril.test.spring.osgi-23-0-0/spring/ After some research I found Snowdrop and am hoping it can help. I am embedding snowdrop-vfs 2.0.0.Final in my bundle, I have switched to using VFSClassPathXmlApplicationContext, and I have configured OSGi to use these VFS modules: <module identifier="org.jboss.vfs"/> <module identifier="org.jboss.osgi.vfs" startlevel="1"/> However, using a location with patterns such as "classpath:spring/*Context.xml" does not seem to work; none of my beans are found: 22:19:35,672 INFO [org.springframework.beans.factory.support.DefaultListableBeanFactory] (MSC service thread 1-1) Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@8a70e3a: defining beans []; root of factory hierarchy Interestingly, using a patternless location that works with ClassPathXmlApplicationContext (classpath:spring/applicationContext.xml) does not work with VFSClassPathXmlApplicationContext: Caused by: java.io.FileNotFoundException: /spring/applicationContext.xml (No such file or directory) at java.io.FileInputStream.open(Native Method) [:1.6.0_26] at java.io.FileInputStream.<init>(FileInputStream.java:120) [:1.6.0_26] at org.jboss.vfs.spi.RootFileSystem.openInputStream(RootFileSystem.java:55) at org.jboss.vfs.VirtualFile.openStream(VirtualFile.java:238) [jboss-vfs-3.0.1.GA.jar:3.0.1.GA] -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/632884#632884] Start a new discussion in Snowdrop at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2082]
