DataPower Web Service Proxy getting 500 error

8k views Asked by At

I got a problem with DataPower. I'm trying to set ws proxy up, but it keeps throwing http 500. I will provide wsdl, java code below.

I've set Remote Endpoint Host as my ip (not localhost):8080 - i host this ws on Eclipse + Tomcat, and Local Endpoint Host to ip of VM - instance of DataPower Gateway Trial with unused port (i use 2911). I uploaded wsdl file and set it up ofc.

I'm trying to test it with SOAP UI, by sending POST request with getUserName method invocation to http://VMip/WebServiceProject/services/UsersCatalog but i get error 500. I think i tried everything but still cant get it working. Please help!

I asked my admin if our firewall isn't blocking incoming traffic, but it's allowed.

I discovered that DataPower accepts request, but it fails to make it's way to host (Tomcat).

I was thinking that it might be a problem with VM network setting, but it throws same error both on bridged and host-only.

You got a connection refused which most likely means you've hit a firewall. Use the troubleshooting tool in DataPower to do a connection test on the port and IP you need to connect to and check that you get a connection. If you do, then you have some issue with the Java service. If not then check any firewall and route between DataPower and the target server.

Make sure you have the NIC's properly set in DataPower if you are using more than one IP/NIC. Only one NIC should have a default gateway, the rest static routes.
