如何使用WSO2 ESB 4.7中的SOAP服务addSequence

Question

我正在尝试使用WSO2 ESB 4.7中的SOAP服务addSequence我正在使用SequenceAdminService.wsdl文件，该文件位于：

https://ip:9443/services/SequenceAdminService?wsdl

在此WSDL中，addSequence方法的输入参数具有Object作为类型。 我看一下服务器代码，WSO2 ESB正在参加addSequence服务的OMElement。

因此，我在pom.xml中添加了此依赖项：

<dependency>
  <groupId>org.apache.ws.commons.axiom.wso2</groupId>
  <artifactId>axiom</artifactId>
  <version>1.2.11.wso2v2</version>
</dependency>

并像这样修改我的代码：

String sequenceXml = this.configTemplate.generateAuthentificationSequence(sequenceName, authorization);

OMElement sequenceElement = null;
try {
sequenceElement = AXIOMUtil.stringToOM(sequenceXml);

} catch (XMLStreamException e) {
    throw (new TechnicalException(e));             
}

try {               
    this.sequenceAdminStub.addSequence(sequenceElement);
} catch (SequenceAdminServiceSequenceEditorException e1) {
    throw (new TechnicalException(e1));
}

但是在运行时，出现此编组错误：

javax.xml.ws.soap.SOAPFaultException: Marshalling Error: class org.apache.axiom.om.impl.llom.OMElementImpl nor any of its super class is known to this context.

任何想法 ？ 谢谢

您可以查看ESB代码并查看其处理方式。

save_sequence.jsp包含添加序列时使用的代码。

SequenceAdminClient.java

public void addSequence(SequenceMediator sequence) throws SequenceEditorException {
    OMElement sequenceElem = sequence.serialize(null);
    try {
        sequenceAdminStub.addSequence(sequenceElem);
    } catch (Exception e) {
        handleException("Error in adding the sequence with the configuration '"
                + sequenceElem + "'", e);
    }
}

SequenceMediator.java

public OMElement serialize(OMElement parent) {
    OMElement sequence = fac.createOMElement("sequence", synNS);
    if (!anonymous) {
        if (key != null) {
            // Use KeySerializer to serialize Key
            ValueSerializer keySerializer = new ValueSerializer();
            keySerializer.serializeValue(key, XMLConfigConstants.KEY, sequence);
        } else if (name != null) {
            sequence.addAttribute(fac.createOMAttribute(
                    "name", nullNS, name));

            if (errorHandler != null) {
                sequence.addAttribute(fac.createOMAttribute(
                        "onError", nullNS, errorHandler));
            }
            saveTracingState(sequence, this);
            serializeChildren(sequence, getList());
        }

        if (parent != null) {
            parent.addChild(sequence);
        }
    } else {
        if (errorHandler != null) {
            sequence.addAttribute(fac.createOMAttribute(
                    "onError", nullNS, errorHandler));
        }
        saveTracingState(sequence, this);
        serializeChildren(sequence, getList());
        if (parent != null) {
            parent.addChild(sequence);
        }
    }

    if (description != null) {

        OMElement descriptionElem = sequence.getFirstChildWithName(new QName(XMLConfigConstants.SYNAPSE_NAMESPACE, "description"));

        if (descriptionElem != null) {
            descriptionElem.setText(description);
        } else {
            OMElement newDescriptionElem = fac.createOMElement("description", synNS);
            newDescriptionElem.setText(description);
            sequence.addChild(newDescriptionElem);
        }

    }

    return sequence;
}
