Generating Java artifacts for JAX-WS applications from a WSDL file
Use JAX-WS tools to generate the Java™ artifacts that are needed to develop JAX-WS web services when starting with a Web Services Description Language (WSDL) file.
Before you begin
When using a top-down development approach to developing Java API for XML-Based Web Services (JAX-WS) web services by starting with a Web Services Description Language (WSDL) file, you must obtain the Uniform Resource Locator (URL) of the WSDL file.
If the WSDL file is a local file, the URL looks like this example: file:drive:\path\file_name.wsdl.
If the WSDL file is a local file, the URL looks like this example: file:/path/file_name.wsdl.
You can also specify local files using the absolute or relative file system path.
About this task
- Service endpoint interface (SEI)
- Service class
- Exception class that is mapped from the
wsdl:fault
class (if any) - Java Architecture for XML Binding (JAXB) generated type values which are Java classes mapped from XML schema types
In addition to using the tools from the
command-line, you can invoke these JAX-WS tools from within the Ant
build environments. Use the com.sun.tools.ws.ant.WsImport
Ant
task from within the Ant build environment to invoke the wsimport
tool. To function properly, this Ant task requires that you invoke
Ant using the ws_ant script.
Procedure
app_server_root\bin\wsimport.bat wsdl_URL
app_server_root/bin/wsimport.sh wsdl_URL
app_server_root/bin/wsimport wsdl_URL
- Use the -verbose option to see a list of generated files when you run the command.
- Use the -keep option to keep generated Java files.
- Use the -wsdlLocation option to specify
the location of the WSDL file. Best practice: A best practice for ensuring that you produce a JAX-WS web services client enterprise archive (EAR) file that is portable to other systems is to package the WSDL document within the application module such as a web services client Java archive (JAR) file or a web application archive (WAR) file. You can specify a relative URI for the location of your WSDL file by using the
-wsdllocation
annotation attribute. For example, if your MyService.wsdl file is located in the META-INF/wsdl/ directory, then run the wsimport tool and use the-wsdllocation
option to specify the value to be used for the location of the WSDL file. This ensures that the generated artifacts contain the correct-wsdllocation
information needed when the application is loaded into the administrative console; for example:wsimport -keep -wsdllocation=META-INF/wsdl/MyService.wsdl
- Use the -b option if you are using WSDL
or schema customizations to specify external binding files that contain
your customizations.
You can customize the bindings in your WSDL file to enable asynchronous mappings or attachments. To generate asynchronous interfaces, add the client-side only customization
enableAsyncMapping
binding declaration to thewsdl:definitions
element or in an external binding file that is defined in the WSDL file. Use theenableMIMEContent
binding declaration in your custom client or server binding file to enable or disable the default mime:content mapping rules. For additional information on custom binding declarations, see chapter 8 the JAX-WS specification.

- Copy the following

- Run the wsimport command from the app_server_root\bin\ directory.
app_server_root\bin\wsimport.bat -keep -verbose ping.wsdl
Operating systems such as AIX® or Linux® source the script to the parent shell to inherit the exported variables by running the following command:
from the. ./setupCmdLine.sh (Notice the space between the periods.)
. /app_server_root>/bin
directory. Run the wsimport command,app_server_root/bin/wsimport.sh -keep -verbose ping.wsdl
app_server_root/bin/wsimport -keep -verbose ping.wsdl
com\ibm\was\wssample\sei\ping\ObjectFactory.java
com\ibm\was\wssample\sei\ping\package-info.java
com\ibm\was\wssample\sei\ping\PingServicePortType.java
com\ibm\was\wssample\sei\ping\PingStringInput.java
com\ibm\was\wssample\sei\ping\PingService.java
The ObjectFactory.java file
contains factory methods for each Java content
interface and Java element interface generated
in the associated ping package. The package-info.java file
takes the targetNamespace value and creates the directory structure.
The PingServicePortType.java file is the generated
service endpoint interface (SEI) class that contains the ping
method
definition. The PinStringInput.java file contains
the JAXB generated type values which are Java classes
mapped from XML schema types. The PingService.java file
is the generated service provider class file that is used by the JAX-WS
client.
