384 CICS Transaction Gateway V5 page 367. The Type is javax.resource.cci.ConnectionFactory, a CCI connection factory. The JNDI name that this is mapped to is not defined in the EJB deployment descriptor, rather in the extension file ibm-ejb-jar-bnd.xmi. Click the Source tab to show the Source pane. The source of the EJB deployment descriptor is shown in this pane and in Figure B-52. CTGTesterCCIEJB CTGTesterCCI itso.cics.eci.j2ee.testercci.CTGTesterCCIHome itso.cics.eci.j2ee.testercci.CTGTesterCCI itso.cics.eci.j2ee.testercci.CTGTesterCCIBean Stateless Container CICS ECI Resource adapter ECI javax.resource.cci.ConnectionFactory Container CTGTesterCCI Remote * Required Figure B-52 CTGTesterCCI EJB deployment descriptor source As shown, most of the names used in the EJB Editor are the same as the tags in the source. The resource reference is defined with the tag . Its id is ResourceRef_1.
To show what the resource reference is bound to, it is necessary to open the ibm-ejb-jar-bnd.xmi file. To view this file, from the J2EE Perspective Navigator view, expand CTGTesterCCIEJB -> ejbModule -> META-INF, right-click ibm-ejb-jar-bnd.xmi, and select Open. Click the Bindings tab to see the Bindings pane. To see the resource reference binding, from the Bindings pane expand CTGTesterCCIEJB -> CTGTesterCCI -> ResourceRef ECI and click ResourceRef ECI. As shown in Figure B-53, the resource reference ECI is bound to the JNDI name eis/CICSA. This can be changed to a deployed connection factory at deploy time. However, when testing we had to define a connection factory in the test server with the JNDI name eis/CICSA so that this reference would be valid and we could test using managed CICS connections. Figure B-53 CTGTesterCCI bean resource reference binding To see the JNDI name our session bean is bound to, from the Bindings pane click CTGTesterCCI. Figure B-54 on page 386 shows that our bean has a suggested JNDI name of ejbs/CTGTesterCCI. This is the same name we used in our Web deployment descriptor as the JNDI name of the session bean, in Figure B-46 on page 379. Because these names are the same, the servlet will look up our session bean using the same JNDI name as it was bound with. Therefore the servlet will find our session bean. Appendix B.
