Antwort: Calling servlet from Pipeline - session lost?

[holger . willenborg]

1. In the pipeline, the cocoon app is the client which requests the data. The cocoon app obviusly doesn't maintain a session connection.

2. If the servlet is not in the Cocoon context, it will not share the session with the Cocoon app.

3. If you put the servlet into the Cocoon app, they should use the same session, so you should be able to share data and to maintain the state.

4. If you put the servlet into the cocoon app anyway, then you might think about making the servlet code serving the XML in a cocoon-specific way, e.g. as a generator.

Hope this helps.
