[jboss-dev-forums] [Design of JBoss jBPM] - Re: committing content from our

[camunda]

Okay, I have started to transfer our code to Commands. The first thing to say is, that we will need a lot of commands (because for working with a fat client we need a command for every communication with the engine), but I think that is not a problem (and I do not know a good way around that).

I have some questions on code conventions in the jbpm project, I haven't figured it our myself and the JBoss-Website seems to be down today :-(

1) What Exception to use if I get invalid data in a command? The JbpmException?

2.) Where to put Hibernate-Queries? We had to build some additional ones for some circumstances. I have seen you put them into a xml-file. This is good for seperating of concerns but I don't like it to much because you get typos in Classes or package names faster there. But anyway, if I have additional queries, can I add them there? Or write them into the commands (not a good idea I think), or just move the HibernateQuery-class we have to the jBPM code base?

3) Which JDK to use? Can I use generics (so loose JDK 1.4 compability)?

Another question: Shouldn't be every attribute in the commands private? Because in the existing commands all attributes are package local...

And the last question: Where to put concrete questions on the already existing commands. In the sourcecode? Here in the forum? Wiki?

Thanks in advance for the answers and a nice weekend
Bernd
