When you open a java stack only PI (possibility available as of PI 7.3) you may notice some changes at a very first sight like for example lack of RWB. There are also some other things which can be found in some other places. If you open the good old Exchange Profile for example you will see that all of the parameters are gone as per screen below:
This is probably because a connection to the Exchange Profile requires a gateway and java stack only systems don't have it (only the ABAP stack of PI has a gateway). The figure below shows a connection setting for the Exchange Profile and system number which will be used for the gateway connection.
Where are my Exchange Profile properties then ??
Don't worry there are still there but they were moved to the NWA (Netweaver Admin).
You can get there from the Administrator application by using the "Property configuration" link.
Next on the services tab you need to select "XPI Service: all config service" as per figure below and you can change all properties in the properties section.
Once you change all the properties you can use the Aii Properties link in the Administrator application and after you press the refresh button you should be able to see all new properties inside as per figure below.
I'd like to thank William Li for his help with this topic.
