如何以編程方式將j2ee.jar添加到Java2WSDL ant腳本？

Question

我正在使用IBM的Rational Application Developer。我有一個包含Java2WSDL任務的ant腳本。當我通過IBM運行它時，它會給編譯器提供錯誤，除非通過運行工具將j2e​​e.jar文件包含在classpath中（它不會在腳本的類路徑中選擇jar文件）。但是，我需要能夠以編程方式調用此腳本，並且它給了我這個錯誤：「java.lang.NoClassDefFoundError：org.eclipse.core.runtime.CoreException」我不確定哪些罐子需要添加或哪裏？由於一個簡單的echo腳本運行，我假設它是j2ee.jar或另一個需要添加的ant jar。我已經將它添加到項目的構建路徑中，但這沒有幫助。 （我還有ant.jar，wsanttasks.jar，插件中的所有ant jar，tools.jar，remoteAnt.jar和swt - 當您單獨運行腳本時，它們都包含在構建路徑中。）

腳本：

<?xml version="1.0" encoding="UTF-8"?>      
<project default="build" basedir="."> 

    <path id="lib.path"> 
    <fileset dir="C:\Program Files\IBM\WebSphere\AppServer\lib" includes="*.jar"/> 
      <!-- 
     Adding these does not help. 
     <fileset dir="C:\Program Files\IBM\SDP70Shared\plugins\org.apache.ant_1.6.5\lib" includes="*.jar"/> 
     <fileset dir="C:\Program Files\IBM\SDP70\jdk\lib" includes="*.jar"/> 
     <fileset dir="C:\Program Files\IBM\SDP70\configuration\org.eclipse.osgi\bundles\1139\1\.cp\lib" includes="*.jar"/> 
     <fileset dir="C:\Program Files\IBM\SDP70Shared\plugins" includes="*.jar"/> 
     --> 
    </path>   

    <taskdef name="java2wsdl" 
      classname="com.ibm.websphere.ant.tasks.Java2WSDL"> 
    <classpath refid="lib.path"/> 
    </taskdef> 

    <target name="build"> 
     <echo message="Beginning build"/> 
    <javac srcdir="C:\J2W_Test\Java2Wsdl_Example" 
      destdir="C:\J2W_Test\Java2Wsdl_Example"> 
     <classpath refid="lib.path"/> 
     <include name="WSExample.java"/> 
    </javac> 
    <echo message="Set up javac"/> 
    <echo message="Running java2wsdl"/> 
    <java2wsdl output="C:\J2W_Test\Java2Wsdl_Example\example\META-INF\wsdl\WSExample.wsdl" 
       classpath="C:\J2W_Test\Java2Wsdl_Example" 
       className= "example.WSExample" 
       namespace="http://example" 
       namespaceImpl="http://example" 
       location="http://localhost:9080/example/services/WSExample" 
       style="document" 
       use="literal"> 
     <mapping namespace="http://example" package="example"/> 
    </java2wsdl> 
    <echo message="Complete"/> 
    </target>     

</project> 

代碼：

File buildFile = new File("build.xml"); 
    Project p = new Project(); 
    p.setUserProperty("ant.file", buildFile.getAbsolutePath()); 

    DefaultLogger consoleLogger = new DefaultLogger(); 
    consoleLogger.setErrorPrintStream(System.err); 
    consoleLogger.setOutputPrintStream(System.out); 
    consoleLogger.setMessageOutputLevel(Project.MSG_INFO); 
    p.addBuildListener(consoleLogger); 

    try { 
    p.fireBuildStarted(); 
    p.init(); 
    ProjectHelper helper = ProjectHelper.getProjectHelper(); 
    p.addReference("ant.projectHelper", helper); 
    helper.parse(p, buildFile); 
    p.executeTarget(p.getDefaultTarget()); 
    p.fireBuildFinished(null); 
    } catch (BuildException e) { 
    p.fireBuildFinished(e); 
    }

A jarfinder搜索表明，因爲您運行在Rational環境之外，所以您需要訪問可能包含該文件的Eclipse核心jar（可能）。
