Thank you very much! The question which had puzzled me for two weeks is resovled now. The following is the configure file: <!DOCTYPE connection-factories PUBLIC | "-//JBoss//DTD JBOSS JCA Config 1.5//EN" | "http://www.jboss.org/j2ee/dtd/jboss-ds_1_5.dtd"> | <!-- | The non-transaction FileSystem resource adaptor service configuration | --> | <connection-factories> | <no-tx-connection-factory> | <jndi-name>NoTransFile</jndi-name> | <rar-name>resource.ear#file.rar</rar-name> | <connection-definition> | javax.resource.cci.ConnectionFactory | </connection-definition> | | </no-tx-connection-factory> | </connection-factories> Thank every one again!
