Export the source files to a jar as shown in the figure.

Open a command prompt and point it to the bin directory of server installation.

Run gsh. This will start the Gshell.

Run the command

title	WSDL Generation command	borderStyle	solid

Administrator@T60J9:/> jaxws/wsgen -classpath C:/WSDL/source.jar -d C:/WSDL/ -wsdl:soap1.1 org.apache.geronimo.samples.jws.CalculatorService

In this command -classpath is used to set source.jar(exported from eclipse) in the classpath, -d defines the location where all the generated artifacts will be placed, -wsdl:soap1.1 suggests a wsdl generation following soap1.1 protocol, org.apache.geronimo.samples.jws.CalculatorService is the SEI used to generate the WSDL.

Once the above command is run Calculator_schema1.xsd and Calculator.wsdl will be generated at C:/wsdl.

Rename Calculator.wsdl as CalculatorService.wsdl and add both the generated files above to WEB-INF directory of the project.

Info

title	Why are we using gsh if we already have a jaxws-tools.bat

This is because there are some issues involved with jaxws-tools.bat in AG 2.1 so we are using a gshell to call the web services generator.

To learn more about GShell refer Gshell section in user guide. To know about more options associated with jaxws. Run jaxws/wsgen -help or jaxws/wsimport -help from gshell.
