ant script using Xpath

[Amirtharaj Chinnaraj]

Hi All,

I am trying to generate web service client using a WSDL through Ant script, it is just a simple exercise, i am trying to do to make myself familar with using binding.xml to overridding the package structure generated by the ant.

her is my build.xml

<?xml version="1.0"?>
<project name="generate-wsdl" basedir="." >      
<property name="jboss.home" location ="C:/jboss-eap-5.1/jboss-as" />
<property name="java.home" location="C:/Program Files/Java/jdk1.7.0_45" /> 

	
	<target name="gen">
	<echo message="Hello, world"/>
    <taskdef name="wsconsume" classname="org.jboss.wsf.spi.tools.ant.WSConsumeTask">
       <classpath>
           <pathelement location="${jboss.home}/client/jbossws-spi.jar" />
		   <pathelement location="${jboss.home}/client/jbossws-client.jar" />
		   <pathelement location="${jboss.home}/client/getopt.jar" />
           <pathelement location="${jboss.home}/client/jbossws-native-core.jar" />
           <pathelement location="${jboss.home}/client/jbossws-common.jar" />
           <pathelement location="${jboss.home}/client/jaxws-tools.jar" />
           <pathelement location="${jboss.home}/client/wstx.jar"/>		  
       </classpath>
    </taskdef>
    
	<!--    -->
	
    <wsconsume
     verbose="true"
     destdir="output"
     sourcedestdir="src"  	 
     keep="true"
	 extension="true"	 
	  binding="${basedir}/bindings.xml"
     wsdl="${basedir}/MyServiceImplService.wsdl">	  
    </wsconsume> 
	
	<jar destfile="${basedir}/client.jar"  >  
	    	<fileset dir="${basedir}/output">
	    		<include name="**/*.class" />
	    	</fileset>
	 </jar>
	
    </target>

</project>

And here is my bindings.xml

<?xml version="1.0" encoding="UTF-8"?>
<bindings
    xmlns="http://java.sun.com/xml/ns/jaxws"
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" version="2.0" wsdlLocation="MyServiceImplService.wsdl">
    <bindings node="definitions/portType[@name='MyServiceImplDelegate']/operation[@name='greetMe']/fault[@name='MyServiceException']">
        <class name="MyFault">
            <javadoc>Exception generated during any operation with the service.</javadoc>
        </class>
    </bindings>
</bindings>

And this is the exception i got while running the the ant script

[wsconsume] parsing WSDL...


[wsconsume] [ERROR] XPath evaluation of "definitions/portType[@name='MyServiceIm
plDelegate']/operation[@name='greetMe']/fault[@name='MyServiceException']" resul
ts in an empty target node
[wsconsume]   line 5 of file:/C:/Users/Achinnaraj/Desktop/testws/bindings.xml

[wsconsume]     Failed to parse the WSDL.

[Ulf Dittmer]

My knowledge of WSDL is shaky, but I don't see any actual bindings, port types etc. - I think that's what the exception says is missing; the XPath is supposed to point to it, but that part is missing. See http://www.w3.org/TR/wsdl#_document-s for what a WSDL normally looks like.

Hi Ulf,

Thanks the for the reply. Actually i didnt sent my WSDL now iam attaching for the reference. i am sure the issue is not with the WSDL, if i remove the line 29 binding="${basedir}/bindings.xml" in the build.xml my ant scripts runs fine and my Clinet is created without any issue .

I am getting the exception on when i try to use the line binding="${basedir}/bindings.xml"

You need to get the namespace right for the the elements referred.
<!-- <bindings node="definitions/portType[@name='MyServiceImplDelegate']/operation[@name='greetMe']/fault[@name='MyServiceException']"> --> <bindings node="wsdl:definitions/wsdl:portType[@name='MyServiceImplDelegate']/wsdl:operation[@name='greetMe']/wsdl:fault[@name='MyServiceException']"> <class name="MyFault"> <javadoc>Exception generated during any operation with the service.</javadoc> </class> </bindings>
