  • You should verify that you have installed JDK (JRE will not be enough). In addition, verify it's setup in your PATH

You are trying to generate partner.jar using WSDL file and you are using "force-wsc-36.1.1.jar" (File as Web Service Connector).

As of WSC-36 connector required an additional framework to generate "partner.jar" call "StringTemplate engine framework".

Download latest "StringTemplate binary" jar file using below link: String Template jar file

Put that String template jar, wsc jar and WSDL files in one location.

  1. Open CMD
  2. Go to the directory where you put your all files.
  3. Fire below command to generate a partner.jar file.

    java -classpath force-wsc-36.1.1.jar;ST-4.0.8.jar com.sforce.ws.tools.wsdlc partner.wsdl partner.jar

    Syntax: Java -classpath [WSC jar file];[String template jar file] com.sforce.ws.tools.wsdlc [Partner.wsdl file] [Ouput file name with .jar extation]
