Answer 1

i said to you that it shouldnt point to ABAP system!
read my solution again
Please ensure system configuration-
>system landscape->system(my system)->Web Application server settings
please check is it pointing to ABAP Server, If yes then change to Java
server then your Application will work.
The two types want different WAS properties. Now if you set
up the WAS so that the BSP works well. There is a possibility that you
can modify the WAS settings when you use WebDynpro launcher. You have
three possibilities to change this:
1. In the UWL connector settings modify the "Web Dynpro Launch System"
property to SAP_LocalSystem. This case the webdynpro uses the URL and
the port of the portal.>> I think this can suit you.
2. In the System Landscape create a new system with the same properties
as the R3_TEST1 but the WAS properties are different. After that you use
the name of the new system as "Web Dynpro Launch System" in the UWL
connector settings. This solution should be used if the SAP_LocalSystem
is different than the necessary WAS settings.
3. You can modify this setting in the configuration also under the
ItemType. You should add the system property and the UWL uses it instead
of the default one.
