This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I would like to use Java Data Objects on a forthcoming project which accesses a relational database and a CICS-based legacy EIS. I know I can use the JCA within my J2EE environment to gain access to both data sources, but I do not understand fully how I can use JDO and JCA together. I've read various documentation which seem to suggest this is possible, but provide little explanation. Has anyone succeeded in using JDO and JCA together in this type of set-up ?
