Question

我正在使用jdk 1.6并开发了一个可以生成xml消息的程序，它工作正常，我能够生成它。当我在unix服务器中部署它时，我得到了jaxb.bind。 marshaller例外，在unix中他们使用的是jdk 1.5。在我的xmlgenerated类中，这些包引用了JRE中的rt.jar，其中所需的包在unix服务器的jdk 1.5中不可用。可以帮助我们如何解决这个问题。

例外是：java.lang.NoClassDefFoundError：javax / xml / bind / Marshaller

代码是：

`

public JaxbXmlMessageGenerator() {
    try {
        jaxbContext = JAXBContext.newInstance("generated");
        xmlOutputFactory = XMLOutputFactory.newFactory();
    } catch (Exception e) {
        e.printStackTrace();
    }

}

public static void main(String[] args) {
    JaxbXmlMessageGenerator jaxbXmlMessageGenerator = new JaxbXmlMessageGenerator();
    System.out.println("-- The Transformed XML Message -- \n"+jaxbXmlMessageGenerator.getMessage());
}

public final String getMessage() {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    try {
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
        jaxbMarshaller.setProperty("jaxb.encoding", "UTF-8");
        jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);

        XMLStreamWriter xmlStreamWriter = xmlOutputFactory
                .createXMLStreamWriter(baos, (String) jaxbMarshaller
                        .getProperty(Marshaller.JAXB_ENCODING));
        xmlStreamWriter.writeStartDocument((String) jaxbMarshaller
                .getProperty(Marshaller.JAXB_ENCODING), "1.0");
        jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

        File file=new File("D:\\eclipse\\file.xml");
        ObjectFactory factory = new ObjectFactory();
        BaNCSLimitRQPT rqpt = factory.createBaNCSLimitRQPT();
        MsgDtlT msgDtlT = factory.createMsgDtlT();
        msgDtlT.setMsgLimitType("FC");
        msgDtlT.setMsgOUID("0507");
        msgDtlT.setMsgTxnCur("USD");
        msgDtlT.setMsgUnBlckInd("2");
        msgDtlT.setMsgBlckExpiryDays("2");
        msgDtlT.setMsgBlckExpiryDayType("1");
        msgDtlT.setMsgTenor("180");
        msgDtlT.setMsgLimitId("1234");

        rqpt.setMsgDtl(msgDtlT);

        JAXBElement<BaNCSLimitRQPT> element = factory
                .createBaNCSLimitRQP(rqpt);         
        jaxbMarshaller.marshal(element, file);
        jaxbMarshaller.marshal(element, System.out);            
        xmlStreamWriter.writeEndDocument();
        xmlStreamWriter.close();            
    } catch (Exception e) {
        e.printStackTrace();
    }       
    return new String(baos.toByteArray());
} }
