ODWEK-JAVA API

Hi,

Just wanted to know whether ODWEK communicates with OD SERVER through intermediate server.We are trying to set up a environment where ODWEK call should not directly hit the OD server instead  it should route via a intermediate server .We are using 8.5.0.8  as OD and ODWEK version .

Hello Satish,
  I am not sure what your architecture is  but you can route network traffic via intermediate server.  If you have a Web application (ODWEK) running on server A and a proxy server B in between the database server C where CMOD runs.  As long as the ports are open and there is a route from Server A to Server C via B. I am not quite sure I understand the requirement here "ODWEK call should not hit OD server directly".


Thanks,
Siva

Hi ,

Thanks for your response.I wanted to know how to establish a communication between ODWEK (Server A) and OD (Server C) via Proxy (Server B).I have a test jar file where OD server entries are hardcoded with user id and password and when i ran the sample script from ODWEK server  the jar file is able to connect to OD server .I want to implement the same setup with a proxy server in between.Hope this explains better.Please let me know if any prerequistes are required to make this happen

Hello Satish,
  You need to have the firewall rules open in the proxy server based on how proxy set up. It is always a good idea to have the user id, password, host name, port in a separate properties file with appropriate security outside the code. That said the server A traffic should not be blocked in server B when it is trying to reach server C (I find telnet ipaddress port# a very useful command to check if traffic is allowed).  Based on how the Server B is routing the traffic your IP address for ServerC could change (If there is a NAT involved). If that's the case then you will have to use the server C (NAT IP) to connect to the OnDemand server.


Thanks
Siva

Just to clarify, the JAR (let's use the word EAR instead) which is having code that has been built using the ODWEK APIs should be deployed on a server that has ODWEK software installed. This means that you can not deploy the EAR on a server other that the server that has ODWEK installed.
Now you may route the requests to the ODWEK server via a proxy server as is done in many implementations.
Hope that clarifies.
