Our application often connects to a different kind of back-ends over web services, MQ, JDBC, proprietary (direct over socket) and other kinds of transport. We already have a number of implementations that let us connect from our application to these back-ends and while all of these implementations implement the common java interface, they do not share anything else.

We have realized that there are signification portions of code that are common for all of these particular connector implementations and we have decided to streamline the development of future connectors through one universal connector. This connector will be capable of formatting messages to a format expected by back-end and sending them using the available transport mechanism. For example, fixed-length message format over MQ or over a socket.

One of the dilemmas we are facing is the most appropriate technology for this kind of connector. So far, our connectors were basic java classes that implement the common java interface. Since we generally host our applications in some Java EE application server, it seems that Java Connector Architecture would be the most appropriate technology for this piece of software. However, implementing JCA compliant connector seems to be relatively complex. What are the palpable benefits of going with the standard – JCA and do benefits justify the additional effort?

  1. Indeed JCA seems the most appropriate technology for you. Already excellent arguments have been made, namely the portability, standardised interface, the connection pooling and transaction support. And don’t forget security.

    With WebSphere Process server the adapters could be exposed as a SCA service which can have a lot of benefits if that’s important for you.

    Also some development tools have extensive support for developing and testing JCA connectors.

    Another benefit is (experienced) Java EE Administrators and Java EE developers (should) know the standard so administration and development should be easy to streamline.

    But in the end you should have to find reasons to implement JCA based on the scope of your project, the future plans you have for your project or maybe within the policy of your company.
