Former Member · ‎03-09-2009

hi all:

I use Deployable Proxy in NWDS to call Web Service(https-SSL)

working on PI7.0 platform

Scenario is :

WSClient(Stateless EJB) -

>Deployable Proxy ---> WS-https

Deployable Proxy setting:

SSL Service Certification : Ignore Service Certification

Run Result is :

Sometimes it works(Really amazing)

Sometimes it doesn't work.

When it doesn't work:

The http response is : HTTP/1.1 500 Internal Server Error

J2EE engine exception log is : pay attention the Strong msg
