[jboss-jira] [JBoss JIRA] Commented: (JBSPRING-3) Resources are not well loaded

Resources are not well loaded ----------------------------- Key: JBSPRING-3 URL: https://jira.jboss.org/jira/browse/JBSPRING-3 Project: JBoss Spring Integration Issue Type: Bug Components: VFS Environment: JBoss 5.1.0.CR1, JBoss 6.x from trunk Reporter: Luca Stancapiano Assignee: Marius Bogoevici Attachments: spring-int.5.x.patch.zip, spring-int.6.x.patch.zip I'm triing spring deployer inside jboss 5.1.0.CR1 and JBoss 6.x from trunk. My application is something as: prova.spring it example example1-context.xml Example1.class ext example2-context.xml Example2.class META-INF jboss-spring.xml jboss-spring.xml is so: <?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'> <beans> <import resource="classpath:it/example/example1-context.xml" /> <import resource="classpath*:it/example/ext/*-context.xml" /> </beans> the first context is loaded correctly (example1-context.xml). The second context (*-context.xml) is not loaded. I've seen inside the code and now I have many doubts on org.springframework.util.AntPathMatcher class inside JBoss. This class compares a path through a pattern. In our case we have: pattern: *-context.xml path: prova.spring/it/example/ext/example2-context.xml theese values are wrong using AntPathMatcher class. AntPathMatcher need the same urls to compare. Theese values should to be something as: pattern: prova.spring/it/example/ext/*-context.xml path: prova.spring/it/example/ext/example2-context.xml or pattern: *-context.xml path: example2-context.xml else it returns always false. Because it seems impossible to create the whole URL for path and pattern, I wrote a VFSPathMatcher rewriting the AntPathMatcher. This matcher takes theese two values and modify path value working only with the last context. I suppose we don't need to compare all subcontexts because they are controlled by the classloader. Using VFSPathMatcher we will get always: pattern: *-context.xml path: example2-context.xml Here there is the new class: /* * JBoss, Home of Professional Open Source. * Copyright 2008, Red Hat Middleware LLC, and individual contributors * as indicated by the @author tags.
