Hi all, for some reasons we need to call a comp.exe from an EJB. As we don't want to violate the EJB contract we are looking for another solution instead of calling it directly from the EJB via Runtime.getRuntime().exec(). We thinking about using JCA 1.5 Questions: 1. Any Comments? 2. any other ideas? 3. Did anybody yet implement a JCA Adapter for calling an executable or - even better - is there an open source implementation out there. Please help me. Regards and thanks Alani
