Error in updating web service publishing parameter

Error:

While updating the web service provider, we must clear the existing web service and recreate otherwise we get the below error.

Error in updating web service publishing parameters: String index out of range: -1

Possible Causes:

1) Adeptia WSDL directory (\AdeptiaServer\ServerKernel\wsdl) expects files having extensions. Any file added with no extensions can cause issue and will generate this error. This error may occur if some files with no extension are manually added in the "..\AdeptiaServer\ServerKernel\wsdl" directory.

2) This can be due to some invalid parameters being filled before submitting the WS provider page.

Solution:

- Verify that all files in "..\AdeptiaServer\ServerKernel\wsdl" directory should have extensions.

- Verify the parameters entered in the WS provider page are valid.
