Question

我正在使用基于SOAP的服务中的Axis2 Wsdl2java，该服务托管在IIS上。我首先设置了requestHeader，然后尝试在客户端中执行Create方法，该方法接受两个参数payload xml作为OMElement，requesType作为字符串，但是如下所示获得异常。

org.apache.axis2.AxisFault: System.Web.Services.Protocols.SoapException: Server was  unable to process request. ---> System.InvalidCastException: Unable to cast object of type 'System.Xml.XmlNode[]' to type 'System.String'.

有人可以帮我理解下面代码的问题，或者为什么我会超越异常？

请参阅下面的客户代码：

 package net.approva.BizRights.Services;

 public class Client{
    public static void main(java.lang.String args[]){
    try
    {
       ApprovalRequestManagerStub stub =
       new ApprovalRequestManagerStub("serverurl.asmx");            
       Create(stub);     
    } 
    catch(Exception e)
    {
       e.printStackTrace();
       System.out.println("\n\n\n");
    }
    }
    /* Create */
    public static void Create(ApprovalRequestManagerStub stub){
        try
        {            
            net.approva.BizRights.Services.ApprovalRequestManagerStub.Create req = new Create();            

            java.lang.String content = "<approvalrequests xmlns=\"http://www.approva.net/ApprovalRequest.xsd\"><approvalrequest><name>USER  002371(ABC)</name><type>OnlyWhatIfAnalysis</type><status>SubmittedForWhatIf</status><priority>Medium</priority><applicationid>2</applicationid><applicationname>SAP AI Connection</applicationname><format>NoConstraints</format><requestdetails><roleassignment><users><user><id>591</id><userid>ABC</userid><lastname>002371</lastname><firstname>USER</firstname><validfromdate>1900-01-01</validfromdate><validtodate>1900-01-01</validtodate></user></users><roles><role revoke=\"false\"><id>3172</id><name>SAP_ICM_S_CUST</name><fromdate>1900-01-02T00:00:00</fromdate><todate>1900-01-01T00:00:00</todate><roletype>4</roletype><description>Commissions: Customizing</description></role></roles></roleassignment><applicationscope><scope displaytext=\"Application\" name=\"firstlevelscope\"><scopevalue displaytext=\"SAP AI Connection\">SAP AI Connection</scopevalue></scope></applicationscope><comment /><asanotheruser /><requestor><id>1</id><userid>administrator</userid></requestor><whatifliveverify>1</whatifliveverify><analysisresults /></requestdetails><requestor><lastname /><firstname /><displayname>administrator</displayname></requestor><applicationscope><scope name=\"firstlevelscope\"><scopevalue>SAP AI Connection</scopevalue></scope></applicationscope><liveverify>1</liveverify></approvalrequest></approvalrequests>";

                                                org.apache.axiom.om.OMFactory fac = org.apache.axiom.om.OMAbstractFactory.getOMFactory();
                                                org.apache.axiom.om.OMNamespace omNs = fac.createOMNamespace("http://www.approva.net/BizRights/Services", null);                                              
                                                org.apache.axiom.om.OMElement _valueObjXML = fac.createOMElement("approvalrequests", omNs);                                                
                                                _valueObjXML.addChild(fac.createOMText(_valueObjXML, content));                          

                                                req.setObjXML(_valueObjXML);

            req.setObjType(WellKnownType.ApprovalRequest);

            BRSoapHeader brSOAP =  new BRSoapHeader();
            brSOAP.setProfileID(1);

            BRSoapHeaderE brSoapHeader = new BRSoapHeaderE();
            brSoapHeader.setBRSoapHeader(brSOAP);       

            net.approva.BizRights.Services.ApprovalRequestManagerStub.CreateResponse res = new CreateResponse();
            res = stub.create(req, brSoapHeader);         

            System.out.println(res.toString());
            System.out.println("Request Creation done using Axis2");
        } catch(Exception e){

首先，您已在内容字符串声明

中包含此行的approvalrequests标记

java.lang.String content = "<approvalrequests xmlns=\"http://www.approva.net/ApprovalRequest.xsd\"><approvalrequest><name>USER  002371(ABC)</name><type>OnlyWhatIfAnalysis</type><status>SubmittedForWhatIf</status><priority>Medium</priority><applicationid>2</applicationid><applicationname>SAP AI Connection</applicationname><format>NoConstraints</format><requestdetails><roleassignment><users><user><id>591</id><userid>ABC</userid><lastname>002371</lastname><firstname>USER</firstname><validfromdate>1900-01-01</validfromdate><validtodate>1900-01-01</validtodate></user></users><roles><role revoke=\"false\"><id>3172</id><name>SAP_ICM_S_CUST</name><fromdate>1900-01-02T00:00:00</fromdate><todate>1900-01-01T00:00:00</todate><roletype>4</roletype><description>Commissions: Customizing</description></role></roles></roleassignment><applicationscope><scope displaytext=\"Application\" name=\"firstlevelscope\"><scopevalue displaytext=\"SAP AI Connection\">SAP AI Connection</scopevalue></scope></applicationscope><comment /><asanotheruser /><requestor><id>1</id><userid>administrator</userid></requestor><whatifliveverify>1</whatifliveverify><analysisresults /></requestdetails><requestor><lastname /><firstname /><displayname>administrator</displayname></requestor><applicationscope><scope name=\"firstlevelscope\"><scopevalue>SAP AI Connection</scopevalue></scope></applicationscope><liveverify>1</liveverify></approvalrequest></approvalrequests>";

然后，您再次在此处添加另一个approrequests标记，

org.apache.axiom.om.OMElement _valueObjXML = fac.createOMElement("approvalrequests", omNs);

尝试执行axis2服务客户端时出现异常
