how to receive data from different datasources and transmit them through JMS

The project is required to receive lot of data(the possible historical weather data of one State) from different datasources, like zip files, data files within a website. The data format is not clear, the files might be txt, pdf, or .xml.

Since it specifies that JMS and JPA should be used for implementation, I am thinking use JMS ObjectMessa开发者_运维问答ge to transfer data to application server. The advantage of Obejct Message is that it can read data as an object and so I can store them as persistent object in memory. And use JPA access them for lata query.

I am looking for a simple and extendable way to do this with JMS and JPA. The data source, data format, data size might change in the future.

Create a client (a sample test class) which will read data from the FSL/INGRA file and create text JMS messages and send them to your server.
