Properties File Resource Adapter
Properties Files play an important role in java applications. Almost every application requires it when it needs to be made configurable through some external control. Sometimes J2EE applications might need to read and write back to the file while participating in some JTA transaction. In those cases it is often required that properties file should revert back to there previous state in case of a failovers. This is practically difficult in file read and write operation performed using simple java IO. In such a case we need better mechanism which can control transaction for any kind of Operations. Until JCA it was difficult and involved proprietary code usage but now we can use JCA.
The Properties File adapter is fully compiant with JCA 1.0 Spec. However as soon as JCA 1.5 containers becomes available the adapter would be upgraded to 1.5 spec as it offers many enhanced features like bidirectional messaging.
The current version of Adapter 1.0 alpha offers following features.
The following limitation however exists owing to the 1.0 Compliancy and being an alpha release.
