Whenever you try to deploy a webservice created using PowerBuilder, you get the following error message on your output painter: “Unknown error when invoking pbwsemit.exe”. In this post i show how to solve it.

Here"s a sample of the output with this error:

When I deploy the project, The PowerBuilder report the 
---------- Deploy: Deploy of p_webservice (14:23:30) 
Checking IIS server... 
Generating .NET assembly file... 
Generating PBD files... 
Generating Web service .asmx and .disco files... 
Deploy failed. 
---------- Finished Deploy of p_webservice (14:23:47) 
---------- Error messages: (14:23:47) 
Unknown error when invoking pbwsemit.exe. 
---------- Finished (14:23:47)

No matter how you play around with the webservice project, no matter what features you use, your deploy always finishes with this error.

As far as I know, this problem happens because your source code is in a network drive. Even if the network drive is mapped locally, this error will occur. That being the case, to deploy your project you must make a copy of it to a local drive and then deploy your project.

I hope that helps.
