Hi there, I don't know where should I post it, as the problem is possibly related to one of: * JBoss 4.0.5GA * Richfaces * Maven ... so I am cross-posting this on Richfaces, JBoss AS and Maven forums. The problem is: I have a web application which is to be deployed on a JBoss 4.0.5GA. I was developing it using web-related features of Eclipse (MyEclipse edition, to be specific), with exploded deployment used on local machine during development. Everything was working ok. Problems started when I tried to deploy WAR built with maven... Application is starting, but AJAX-related features of Richfaces are not working: after submitting a4j:form blank pages are being rendered without any error message, reRender-related features are not working on AJAXified pages etc... The strange thing is, that my application is working correctly in two situations: * when it is deployed by Eclipse as an exploded archive * when such an exploded archive is manually packed into a .war file by me and deployed. but is NOT working, when maven creates an archive... I've made sure compiler is set to source and target version of 1.5 in both Eclipse and maven configuration. I've tried to compare created archives and there are only two differences: * when eclipse is setting up a deployment folder, it puts compiled resources of my project's sub-modules directly into WEB-INF/classes folder. When maven is building an archive separate .jar files for each module are created and put in WEB-INF/lib folder. One of those sub-modules is containg common JSF files (taglibs, some converters defined within a sub-module's faces-config.xml etc). * compiled .class files differ by a slight margin (like 4450 bytes vs 4467 bytes) in size. All library jars in the WEB-INF/lib folder are the same in both cases.... I'm astonished by this situation. What's more unfortunate is that I have absolutely no idea how to chase this problem further... Any ideas would be highly appreciated... here comes full list of my library JARs: activation-1.0.2.jar antlr-2.7.6.jar asm-1.5.3.jar batik-awt-util-1.6-1.jar batik-ext-1.6-1.jar batik-gui-util-1.6-1.jar batik-util-1.6-1.jar cglib-2.1_3.jar commons-beanutils-1.7.0.jar commons-beanutils-core-1.7.0.jar commons-cli-1.1.jar commons-codec-1.3.jar commons-collections-3.2.jar commons-dbcp-1.2.2.jar commons-digester-1.6.jar commons-el-1.0.jar commons-fileupload-1.2.1.jar commons-io-1.3.2.jar commons-lang-2.3.jar commons-logging-1.1.1.jar commons-pool-1.3.jar commons-validator-1.3.1.jar dom4j-1.6.1.jar ejb3-persistence-1.0.2.GA.jar el-api-1.0.jar el-ri-1.2.jar geronimo-j2ee_1.4_spec-1.0.jar hibernate-annotations-3.4.0.GA.jar hibernate-commons-annotations-3.1.0.GA.jar hibernate-core-3.3.1.GA.jar itext-1.4.8.jar java-core-2.4.1.jar javassist-3.8.0.GA.jar jaxb-api-2.1.jar jaxb-impl-2.1.9.jar jaxws-api-2.1.jar jaxws-rt-2.1.5.jar jsf-api-1.1_02.jar jsf-facelets-1.1.14.jar jsf-impl-1.1_02.jar jsr181-api-1.0-MR1.jar jsr250-api-1.0.jar jstl-1.1.0.jar jta-1.1.jar junit-4.4.jar jyaml-1.3.jar log4j-1.2.14.jar mimepull-1.3.jar mysql-connector-java-5.0.5.jar ojdbc-10.2.0.4.jar oro-2.0.8.jar p4pl-core-1.0-SNAPSHOT.jar p4pl-core-ws-1.0-SNAPSHOT.jar p4pl-www-commons-1.0-SNAPSHOT.jar resolver-20050927.jar richfaces-api-3.1.6.GA.jar richfaces-impl-3.1.6.GA.jar richfaces-ui-3.1.6.GA.jar saaj-api-1.3-SNAPSHOT.jar saaj-impl-1.3-SNAPSHOT.jar saaj-impl-1.3.2.jar slf4j-api-1.5.6.jar slf4j-log4j12-1.5.6.jar spring-2.5.6.jar spring-test-2.5.6.jar stax-api-1.0.jar stax-ex-1.2.jar streambuffer-0.8.jar tomahawk-1.1.8.jar utils-1.07.jar wstx-asl-3.2.3.jar xercesImpl-2.8.1.jar xml-apis-1.3.03.jar xmlParserAPIs-2.0.2.jar View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4225687#...
