java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult

Question

I have created a web service in netbeans 6.7 and one project for client. The web service has a method which does some query from database and returns me an array. Calling the web service method in client.jsp file in web clients service gives error :

javax.servlet.ServletException: java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclipse/jdt/core/compiler/IProblem;
    org.apache.jasper.servlet.JspServlet.service(JspServlet.java:273)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
    org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter(MonitorFilter.java:390)

root cause

java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclipse/jdt/core/compiler/IProblem;

I have imported jars from hadoop.

I met the same exception with you. In my cases, it's caused by the jetty library conflicts with Hadoop/HBase libraries( maybe both contain org.eclipse.jdt.internal.compiler.CompilationResult method). I solve this bug by adding following exclusions into Hadoop/HBase dependencies:

      <dependency>
      <groupId>org.apache.hadoop</groupId>
      <artifactId>hadoop-common</artifactId>
      <version>${hadoop.version2}</version>
      <exclusions>
        <exclusion>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jetty</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jetty-util</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jsp-2.1</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jsp-api-2.1</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>servlet-api-2.1</artifactId>
        </exclusion>
        <exclusion>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
        </exclusion>
        <exclusion>
            <groupId>javax.servlet.jsp</groupId>

        <exclusion>
            <groupId>tomcat</groupId>
            <artifactId>jasper-compiler</artifactId>
        </exclusion>
        <exclusion>
