Thread: dbt-4 (tpc-app) kit
Hi everyone, I've starting putting together a kit based on the TPC-App, which is a business-to-business Web services workload. I'm starting to implement it as a Java EJB and have the most of the interactions implemented with a simple single threaded driver. The code is available here:http://prdownloads.sourceforge.net/osdldbt/dbt4-0.2.tar.gz?download I don't think my Java skills are very good, so if anyone would like to help, let me know. -- Mark Wong - - markw@osdl.org Open Source Development Lab Inc - A non-profit corporation 12725 SW Millikan Way - Suite 400 - Beaverton, OR 97005 (503) 626-2455 (office) (503) 626-2436 (fax) http://developer.osdl.org/markw/
Mark, I'd like to help out, let me know what you need help doing. Personally, doing this with EJB's is distasteful, but I'll help where I can.

Hi Dave, Oops, EJB's are distasteful? My experience in this area is quite lacking. Not that I necessarily want to be 100% strict but the spec says this needs to conform to WS-I BP 1.0 specification, which I understand is basically using the SOAP transport? I just thought it would be nice to have something that could be plugged into any application server (Geronimo, JBoss, etc.) with minimal configuration changes and that was where I started. I don't mind doing away with the EJB altogether. What do you suggest? To give you a little better idea of where I'm at, I have most of 7 of 9 interactions implemented, the remaining two I haven't started. The driver needs to be expanded to simulate multiple users. I haven't started any of the post processing or data collection scripts yet and some of that can be used from our other kits. My Java programming style should probably be reviewed too. ;) Mark On Fri, 2 Sep 2005 15:17:46 -0400 Dave Cramer <pg@fastcrypt.com> wrote: > Mark, > > I'd like to help out, let me know what you need help doing. > > Personally, doing this with EJB's is distasteful, but I'll help where > I can. > > Dave > On 2-Sep-05, at 12:53 PM, Mark Wong wrote: > > > Hi everyone, > > > > I've starting putting together a kit based on the TPC-App, which is a > > business-to-business Web services workload.

However strictly speaking, many people are going to want to see EJB's as this is what the appserver types like to use. > > To give you a little better idea of where I'm at, I have most of 7 > of 9 > interactions implemented, the remaining two I haven't started.

If I have some time, I'll look at it some more, I've come to like using the spring framework. This allows something referred to as IOC (Inversion of Control) Basically, the problem is how to stub test code in when we have static factory objects, the solution is to build the application using a container which specifies the concrete classes which are instantiated. This would in theory allow us to have tow versions. One which uses hibernate, and the other which uses EJB's. So one thing to think about is to code in interfaces more, and instantiate concrete classes which implement the interface.

I'll probably need some coaching though... Mark

At least part of it.I've given some thought as to how to code this in hibernate, it shouldn't be too hard. > > Mark > > ---------------------------(end of > broadcast)--------------------------- > TIP 4: Have you searched our list archives? > > http://archives.postgresql.org > >
