Re: Enterprise Java -- JAVA400-L

Honestly, I am the middle man here.

Web service: We want a middle tier to use SOAP (or whatever it's called) to
and from our web server. The java web service would communicate with the
System i, MS SQL and other required databases. This way we only have one
hole through the DMZ to a specific server (if we can even do that).

We are in the planning stages on this and are first determining if we should
do RPG, Java, or .NET. The web developer said he would like to use Enterpise
java beans and didn't think the JVM on i5/OS supported it without the
full-blown WebSphere App. Server. I thought it would and we could just
install JBoss to make use of them.

Hi Mike,

I think there are opportunities for miscommunication here. "Web
service" means something specific to most Java developers and that's
something substantially different from just accessing multiple databases.

Secondly, your answer really doesn't tell us anything about the
"enterprise" needs of your application(s.) So we can't really say if just
a
web container like Tomcat or Jetty is sufficient or if you need something
that supplies more services. There are a lot of options around.

"persistent data connections" doesn't sound like a very good idea at
first, but that's essentially what connection pools provide, and you
should
probably look to using those regardless of whether you use a web or
J(2)EE container. There are also a number of other factors that
contribute
to database related performance beyond just connection persistence.
