You deploy an EJB JAR module as described in Tools for Deployment.
You can keep the generated source for stubs and ties by adding the -keepgenerated flag to the rmic-options attribute of the java-config element in domain.xml. If you include this flag when you deploy the EJB JAR module, the generated source is kept in domain-dir/generated/ejb/j2ee-apps/app-name/module-name if it is in an application or domain-dir/generated/ejb/j2ee-modules/module-name if it is in an individually deployed EJB JAR module. For more information about the -keepgenerated flag, see the Sun Java System Application Server Platform Edition 8.1 2005Q2 Update 2 Administration Reference.
Generation of stubs and ties is performed asynchronously, so unless you request their generation during deployment (for example, using the --retrieve option of the asadmin deploy command), stubs and ties are not guaranteed to be available immediately after deployment. You can use the asadmin get-client-stubs command to retrieve the stubs and ties whether or not you requested their generation during deployment. For details, see the Sun Java System Application Server Platform Edition 8.1 2005Q2 Update 2 Reference Manual.
