Re : servlets and intermediate data

Here is my job description.

I'm responsible for servlets which call other servlets doing database jobs.

Unfortunately, he the man who is resposible for database connection are not ready for me to serve servlets.

So I have no choice but to do my job assuming that they are ready.

Consequently I decided to make the quiry result in the format of XML file which possibly on the Tomcat server.

Do I have to use FileInputStream and FileOutputStream?

Do I have to implement the Serializable interface?

And after the db servlets are ready how can we exchange data which should be XML?

I want the data to stay structured.

Give me some comments.

Thanks.

When your servlet receives a request, you can determine which servlet to use and call it by using HTTP request.
The other servlet will return the data in a specific format.
Now you have to convert this data to XML and send it back to your servlet client.
The XML file can be creted in the memoty (without using files) and serialized as string to the response output stream (writer).

Don't use Serializable objects, because you will have to have a java client. The result should be pure XML string.
