蚂蚁apache NoClassDefFoundError

Question

在构建文件build.xml时，我遇到了一些问题。我知道javac标记的类路径存在一些问题，但我不知道如何解决它。

[java] Exception in thread "main" java.lang.NoClassDefFoundError: javax/ws/rs/core/Response

我的项目库位于“/WebContent/WEB/lib/”中，这是我的文件"build.xml"：

<property name="src" value="\${basedir}/src" />  
<property name="build" value="classes" />  
<property name="dist" value="dist" />  
<property name="package" value="*" />  

<target name="init">  
<echo> Criando os diretorio classes, doc e dist.</echo>  
<mkdir dir="..\${build}" />  
<mkdir dir="..\${dist}" />  
</target> 

<target name="compile" depends="init" >  
<echo> Compilando o projeto.</echo>  
<javac srcdir="\${src}" destdir="..\${build}" includeantruntime="false">
    <classpath>
    <fileset dir="\${basedir}/WebContent/WEB-INF/lib/">
       <include name="jersey-server-1.4.jar" />
    </fileset>
  </classpath> 
</javac>
</target>  

<target name="dist" depends="compile">  
<echo> Gerando o .jar do projeto.</echo>      
<jar jarfile="..\${dist}/InfosoundWebApp.jar" basedir="..\${build}">  
    <!-- Tornando o jar executável-->  
    <manifest>  
        <attribute name="Main-Class" value="com.informatec.restfull.ServerRestfull"/>             
    </manifest>  
</jar>  
</target>  

<target name="all" depends="dist">  
<echo> Executa o projeto.</echo>  
<java jar="..\${dist}/InfosoundWebApp.jar" fork="true" />
</target>  

<target name="clear">  
    <delete dir="..\${build}" />  
    <delete dir="..\${dist}" />      
</target>

​

如果有人能帮我，我会很感激的。

看起来您正在尝试从JavaEE运行JavaSE应用程序。类javax/ws/rs/core/Response仅在JavaEE (在您的ws服务器上)下可用。您的build.xml target="all“尝试在JavaSE下执行您的webapp应用程序。把它处理掉。将target="dist“作为默认目标，然后将jar上传到您的etc服务器(Tomat等)。
