Cause

This error is generated because the default set of configuration values in web.config require IIS to treat the web site as an application but this has not been configured.

Solution:
1.Control Panel > Administrative Tools >IIS
2. Open webiste properties (Default Web Site>Your Website >Right click > Properties)
3. If the "application name" (under "Application Settings" on the "Directory" tab) is greyed out then click '[Create]' and then '[OK]'.

Error: Path for project must have only one segment

Error: Path for project must have only one segment

Even Though google shows 995,000 pages containg the text “Path for project must have only one segment” – None of them really explains what this error mean – Except if you look at the source code of WorkspaceRoot class, particularly ‘getProject’ method:

This problem usually occurs when you try to access a project name/path,etc, when it is not avialable or you might have forget to instantiate the IProject object or try to instantiate the IProject with different name.

Solution: Have a look at your code where you are calling

getProject.

Check names, paths are called correctly.
