Error while creating SOAP stubs

I am getting the following error while generating SOAP stubs from the wsdl.

"The method getXmatters50HttpSoap11Endpoint(URL) from the type Xmatters50Locator refers to the missing type Xmatters50PortType

Xmatters50Locator.java

/xmattersTest/src/com/xmatters/www/webservices/schema

line 50 Java Problem"

Has anyone faced this issue while generating SOAP stubs?

I followed these steps.

• Created a new Java project in my eclipse workspace.
• File -> New  -> Other -> Web Service Client.
• In the wizard, gave the wsdl company specific url "https://<company_configuration>na1.xmatters.com/api/services/xmatters-5.0?wsdl" and settings as described in the screenshot ( WebService client step 2.png)
• PFA the screenshot for the error "Xmatters50PortType Not found error.png"

Any help is appreciated
