Fail to open mapping debugger in client machine

Question

I have installed OWB 10.2.0.2 successfully on HP-UX server, and designed some db mappings and workflow on that.
Meanwhile, I installed OWB 10.2.0.2 as client on Windows XP.
Currently, I could deploy and execute the mappings and workflow in Control Center from client side, which could approve that the control center service is running OK on client, but when I tried to open mapping debugger, I met the following errors:
Mapping Debugger Error:
oracle.wh.service.sdk.mapping.debugger.WBMappingDebuggerException:
DBG1032:Cannot connect to location MAPPING_LOCATION:
java.sql.SQLException:Io exception: The Network Adapter could not establish the connection
You are not currently connected to a Control Center schema. You must establish a connection
to a Control Center schema before proceeding with the current debug session. If a connection
is not established , the debug session will end
It is strange that I could open the mapping debugger from server side, i.e. in XWindow of HP-UX, without any other modification, like redeploy or restart the control center service.
Could anyone give me a hand on the issue?

Answer 1

If your server serves a web page with a link to a specific drive letter then when a client clicks the link it is going to look for a file on thier client machine.
Do you understand the client server relationship?
The href attribute of your anchor tag must point to an http or ftp address for a client to remotely access or download that file.
<%= request.getContextRoot() %> will give you the context root, then you can place the rest of the path. The files must be within the context of the http web server.
