Hi, I m not sure whether this would help Based on the article http://cwiki.apache.org/GMOxDOC11/jboss-to-geronimo-jdbc-migration.html Geronimo does not support accessing external resources(JDBC datasources) by setting JNDI properties at runtime. This is because reference resolution is done at deploy time and is based on the JSR-77 object names of the target component. What is the best way to provide the JTA datasource ,by boostraping a microcontainer or using the Geronimo transaction manager ?
