jaws vs. jbosscmp-jdbc suggestion

[lefou]

Hi,

I plan to migrate an EJB 1.1 project to JBoss (3.2.x). Can anybody tell me the differences between jaws.xml and jbosscmp-jdbc.xml. Do they have the same syntax? Which is more capable? Is it possible with one of these both, to connect to more than one datasource?

Any suggestions or links to a good comparison would be nice.
Many thanks in advance!

This sounds like a misunderstanding...

There is no jaws.xml, there is a jaws.dtd and this is - according to my understanding - the descriptor file for the jbosscmp-jdbc.xml file.

And of course the latter is still a very important configuration file for JBoss.

I cannot believe this. The JBoss 3.0 Documentation speak from a jaws.xml in chapter 6 with the xml root element \<jaws\>, but the JBoss Admin Development Guilde speak about a jbosscmp-jdbc.xml file with root element \<jbosscmp-jdbc\>

So, both exists and both define some \<datasource\> ... \</datasource\> stuff.

Totally confused. Can anybody help?

JAWS was the old cmp1.1 engine that is obsolete and no longer supported. The jbosscmp-jdbc.xml is the cmp2.x engine that supports 1.1 style entity beans. The cmp2.x engine is far more capable.

Is it possible, to define more than one datasoure (with different transaction levels) ?
