Re: How to disable Transactions in Cayenne

Re: problem when HessianServlet is called (nullpointerexception) cayenne 3.0.2

Where is your cayenne.xml located in the assembled .war file? Wonder if it goes missing somehow when you assemble your webapp. Andrus On Dec 6, 2011, at 4:39 AM, Papa Issa DIAKHATE wrote: > Hello guys, > > i'm using cayenne 3.0.2 and i get NullPointerException when the servlet > mapped to He

Re: How to disable Transactions in Cayenne

Checking "Container-managed transactions" for the DataDomain in the Modeler would prevent Connection.commit() from being executed. Not sure if this is the solution you are looking for. Juergen's approach sounds good too - DataSource (and by extension Connections, Statements, etc.) is opaque to

REST web services with Cayenne
