2.8. Deploying Metro endpoint

Before you deploy or publish your endpoint, you will need to package your endpoint application into a WAR file. The requirements when building a WAR:

  • All WSDLs, Schema files should be packaged under WEB-INF/wsdl dir. It is recommended not to package the WSDL if you are doing Java-first development.
  • WebService implementation class should contain @WebService annotation. Provider based endpoints should have @WebServiceProvider annotation.
  • wsdl, service, port attributes are mandatory for Provider based endpoints and can be specified in @WebServiceProvider annotation or deployment descriptor (sun-jaxws.xml).
  • Deployment descriptors, web.xml, web services deployment descriptor (sun-jaxws.xml or 109 or spring)

2.8.1. The WAR Contents

Typically, one creates the WAR file with a GUI development tool or with the ant war task from the generated artifacts from wsimport, wsgen, or apt tools.

For example, a sample WAR file starting from a WSDL file:

Sample WAR contents (WSDL First)

        WEB-INF/classes/hello/HelloIF.class SEI
        WEB-INF/classes/hello/HelloImpl.class Endpoint
        WEB-INF/sun-jaxws.xml JAX-WS RI deployment descriptor
        WEB-INF/web.xml Web deployment descriptor
        WEB-INF/wsdl/HelloService.wsdl WSDL
        WEB-INF/wsdl/schema.xsd WSDL imports this Schema

2.8.2. Using sun-jaxws.xml

Metro defines its own deployment descriptor, which is also known as JAX-WS RI deployment descriptor - sun-jaxws.xml.

Here is the schema for sun-jaxws.xml:

The <endpoints> element contain one or more <endpoint> elements. Each endpoint represents a port in the WSDL and it contains all information about implementation class, servlet url-pattern, binding, WSDL, service, port QNames. The following shows a sun-jaxws.xml file for a simple HelloWorld service. sun-jaxws.xml is the schema instance of sun-jaxws.xml.

    <?xml version="1.0" encoding="UTF-8"?>
  • Endpoint attribute
Attribute Optional Use
N Name of the endpoint
Y Primary wsdl file location in the WAR file. E.g. WEB-INF/wsdl/HelloService.wsdl. If this isn't specified, JAX-WS will generate and publish a new WSDL. When the service is developed from Java, it is recommended to omit this attribute.
Y QName of WSDL service. For e.g. {http://example.org/}HelloService. When the service is developed from java, it is recommended to omit this attribute.
Y QName of WSDL port. For e.g. {http://example.org/}HelloPort. When the service is developed from Java, it is recommended to omit this attribute.
N Endpoint implementation class name. For e.g: hello.HelloImpl. The class should have @WebService annotation. Provider based implementation class should have @WebServiceProvider annotation.
N Should match <url-pattern> in web.xml
Y Binding id defined in the JAX-WS API. The possible values are:
If omitted, it is considered SOAP1.1 binding.
Y Enables MTOM optimization. true or false. Default is false.
