The wsgen command-line tool generates the necessary portable artifacts required for Java API for XML Web
Services (JAX-WS) applications when starting from Java code. This tool will generate a WSDL file only when requested.
When using a bottoms-up approach to develop JAX-WS web services and you are starting from a service endpoint
implementation, use the wsgen tool to generate the required JAX-WS portable artifacts.
The wsgen tool accepts a properly annotated service endpoint implementation using the
@WebService annotation as input and generates the following portable artifacts:
any additional Java Architecture for XML Binding (JAXB) classes that are required to marshal and unmarshal the message contents.
a WSDL file if the optional -wsdl argument is specified. The wsgen tool does
not automatically generate the WSDL file.
The command line syntax is:
wsgen [options] service_implementation_class
The service_implementation_class name is the only parameter that is required. The following parameters
are optional for the wsgen command:
-classpath <path>
Specifies the location of the service implementation class.
-cp <path>
This is the same as -classpath <path>.
-d <directory>
Specifies where to place the generated output files.
-extension
Specifies whether to allow custom extensions for functionality not specified by the JAX-WS specification. Use of the extensions can result in applications that are not portable or do not interoperate with other implementations.
-keep
Specifies whether to keep the generated source files.
-r <directory>
This parameter is only used in conjunction with the -wsdl parameter. Specifies where to
place the generated WSDL file.
-s <directory>
Specifies the directory to place the generated source files.
-wsdl [:protocol]
By default, wsgen does not generate a WSDL file. This optional parameter causes
wsgen to generate a WSDL file and is typically only used to allow a developer to
review a WSDL file before the endpoint is deployed. The protocol is optional and specifies the
protocol used in the wsdl:binding. Valid values for protocol are
soap 1.1 and Xsoap 1.2. The default value is soap 1.1. The
Xsoap 1.2 value is not standard and can only be used in conjunction with the
-extension option.
-servicename <name>
This parameter is only used in conjunction with the -wsdl option. Specifies a
wsdl:service name to be generated in the WSDL file. For example:
-servicename "{http://mynamespace/}MyService"
-portname
This parameter is only used in conjunction with the -wsdl option. Specifies a
wsdl:port name to be generated in the WSDL file. For example:
-portname "{http://mynamespace/}MyPort"
Note that you must run wsgen against a Java class that has already been compiled (not
against the source program), and if you specify a directory in which the tool should place generated files
such as the WSDL, that directory must exist before you run the program. Also, you must run the tool against
an implementation class, and not an interface.
