Managed Code Sample Using the Siebel Resource Adapter

The following is a code sample using the Siebel Resource Adapter in a managed environment. The sample is a servlet that makes a simple invocation to a business service using the generated JCA code. (For more information about generating code, see About the Siebel Code Generator.)

The JCA ConnectionFactory is obtained through JNDI. Credentials are obtained at run time from the JAAS Subject passed to the servlet. The connect string and language are obtained from the deployment descriptor (ra.xml). Other connection parameters are obtained from the siebel.properties file.

Note: The siebel.properties file must be in the JVM classpath and must be specified explicitly when the business service instance is created.
