Access to HTTP Environment data

We have an RPG CGI application that we call from other RPG CGI
applications that we use for checking for valid cookies, checking our
unique security rules, and for doing some activity logging. When RPG CGI
app A calls RPG CGI app B, app B has full access to the HTTP environment
data and can do any of the CGI API calls.  We now want to use this same
RPG CGI application from a java application. We created the RPG CGI app
as a stored procedure in order to make it easier to evoke from java but
when the java app runs the stored procedure the RPG CGI app is not able
to retrieve any of the HTTP environment information. I had originally
thought it was because the java app as running in a Websphere job where
CGI apps run in an HTTP server job but a Java app has full access to the
HTTP environment information. Could what we are seeing be caused by the
call to a stored procedure ? If we used a native call to the RPG CGI app
from Java instead might it give the RPG CGI app access to the HTTP
environment ? Our last resort is to have the java app retrieve the HTTP
data and pass it as parameters to the RPG CGI app so it can still do the
other functions it needs to do.
