Question

我正在使用axis2访问由其他人作为客户端公开的Web服务，并且我已经为abcStub .java创建了一个包装器方法（通过运行一些批处理生成Stub java文件）并尝试实例化Stub文件在包装器java文件中。但我得到以下错误：

我认为这个问题一定存在问题

org.apache.neethi.PolicyEngine.getPolicy(Ljava/lang/Object;)Lorg/apache/neethi/Policy;

或者可能是我错了。无论哪种方式，不知道如何解决。如果有人知道面对/解决过这个问题会有很大的帮助。

我在接下来的电话中得到了这个：

public String getAppDeclWrapper(String session, String parentAgent, String mirsTxnNo, String strReason, String isApprove, String modifiedBY){ String returnString = null; try {



         mtmrsLogger.info("Entering into Approve Decline procedure, Starting to send Status to MIRS");
               MIRSRemittanceServicesStub stub  = new MIRSRemittanceServicesStub(); //Error occurs at this line

               ApproveDecline approvedEcline = new ApproveDecline();
               ApproveDeclineResponse approveResponse =  new ApproveDeclineResponse();
               approvedEcline.setCParentAgent(parentAgent);
               approvedEcline.setMirsSession(session);
               approvedEcline.setModifiedBy(modifiedBY);
               approvedEcline.setRefNo(mirsTxnNo);
               approvedEcline.setStrReason(strReason);
               approvedEcline.setIsApprove(isApprove);

mtmrsLogger.info("Entering into Approve Decline procedure, Starting to send Status to MIRS"); MIRSRemittanceServicesStub stub = new MIRSRemittanceServicesStub(); //Error occurs at this line ApproveDecline approvedEcline = new ApproveDecline(); ApproveDeclineResponse approveResponse = new ApproveDeclineResponse(); approvedEcline.setCParentAgent(parentAgent); approvedEcline.setMirsSession(session); approvedEcline.setModifiedBy(modifiedBY); approvedEcline.setRefNo(mirsTxnNo); approvedEcline.setStrReason(strReason); approvedEcline.setIsApprove(isApprove);

我猜您的类路径上有多个版本（或无效版本）的PolicyEngine。我认为你在servlet引擎中运行。请尝试以下代码来确定此版本的存储位置并进行修复：

org.apache.neethi.PolicyEngine.class.getProtectionDomain().getCodeSource().getLo‌cation()

进行Web服务调用时出错
