Re: [Springframework-developer] Spring - JBossTS integration

[Jonathan H. <jon...@re...>]

Thanks Mark.

In that article I think they used the approach of wiring up 
the TransactionManager and UserTransaction implementations 
as beans and linking them to the JtaTransactionManager in 
the .xml config file.

That will work fine as long as no additional setup code is 
needed.  I guess the reason Jotm is different is that its 
implementation class cannot work as a bean in this way.

The .xml config approach has some nice effects, like not 
requiring JBossTS build to depend on Spring classes or v.v. 
I may stick with it if it proves flexible enough.

I guess there is also a middle ground where any setup that 
is needed is put into the constructor or static block in a 
bean class that subclasses the TM/UT implementations. Seems 
odd Jotm integration did not go down that path - there must 
be some reason for requiring the compile code coupling that 
currently exists here.

Jonathan.
