Hi All, I have a quick question regarding a problem I had been experiencing with RestEasy 1.1-RC2 and looking up a datasource in JNDI. I don't believe this is a RestEasy bug, it seems to be related to one of the jar files that ships with resteasy. I have a resteasy easy servlet that I deploy onto JBOSS 5.0.1GA. At some point in my resteasy application I go and lookup my datasource using: | InitialContext ctx = new InitialContext(); | DataSource ds = (DataSource)ctx.lookup( "java:comp/env/jdbc/SomeDataSource" ); | However, the datasource is coming back as null. I did a listing of the JNDI jdbc context, and I see the DS in the context, it's just coming back at null. I know the datasource is there (configured in JBOSS) because I can get it, and use it via other non-resteasy servlets. I was able to fix this, be removing multiple .jar files that ships with RestEasy, ( by remove, I mean not deploying some jars with my webapp). I basically tried to guess which jars were already included with JBOSS 5. My question is: Does anyone know what jar file may have caused this? So that I don't deploy it in the future. I'm guessing this may have occured with other JBoss projects but I was unable to find the correct search words to look this up. Also, can anyone recommend, a minimum set of jars to include, assuming I will be running on Jboss 5.0.1? FYI, here are the jars that ship with RestEasy 5.0.1: ----------------------------------------------------------- activation-1.1.jar async-http-jbossweb-1.1-RC2.jar async-http-servlet-3.0-1.1-RC2.jar async-http-tomcat6-1.1-RC2.jar commons-codec-1.2.jar commons-httpclient-3.1.jar commons-logging-1.0.4.jar FastInfoset-1.2.2.jar javassist-3.6.0.GA.jar jaxb-api-2.1.jar jaxb-impl-2.1.8.jar jaxrs-api-1.1-RC2.jar jboss-common-core-2.2.10.GA.jar jboss-logging-spi-2.0.5.GA.jar jbosscache-core-3.0.3.GA.jar jettison-1.0.1.jar jetty-6.1.15.jar jetty-util-6.1.15.jar jgroups-2.6.7.GA.jar jsr250-api-1.0.jar jta-1.1.jar jyaml-1.3.jar mail-1.4.jar resteasy-atom-provider-1.1-RC2.jar resteasy-cache-core-1.1-RC2.jar resteasy-jaxb-provider-1.1-RC2.jar resteasy-jaxrs-1.1-RC2.jar resteasy-multipart-provider-1.1-RC2.jar resteasy-spring-1.1-RC2.jar resteasy-yaml-provider-1.1-RC2.jar scannotation-1.0.2.jar servlet-api-2.5-20081211.jar servlet-api-2.5.jar sjsxp-1.0.1.jar slf4j-api-1.5.2.jar slf4j-simple-1.5.2.jar stax-api-1.0.jar webserver-1.3.3.jar Thanks for any help View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4229776#...
