The exception was thrown during a look-up of the connection factory that is used on a call when the value of the remoteComType property is CICSJ2C, IMSJ2C, or IMSTCP. The remoteComType property is in the linkage options part, in the callLink element for the called program.
For CICSJ2C and IMSJ2C the name of the connection factory is determined by the resource adapter installed on the application server used to run the calling program. The JNDI name of the resource adapter being used is the value that you set in the location property of the same callLink element.
For IMSTCP the connection factory is the connection factory required by IMS™ Connector for Java™.
For CICSJ2C and IMSJ2C make sure that the resource adapter is defined properly in the J2EE environment and that the value for the location property is correct in the callLink element for the called program.
For IMSTCP, make sure that the IMS Connector for Java jar files are included in the classpath when the calling application is started.
