Issue with Axis WebService.

Question

Hi,
I have written a web service, which accepts two strings as parameter(echoService method). And created WSDD file for the same and it works fine. Then I created a webservice which supports attachments, this code also works fine. When I merge this two WebServices and try to invoke "echoService" from client code, I am getting the following error.
java.io.IOException: Type {ElementService}DataHandler is referenced but not defined.I assume, its the problem with the wsdd file "typeMapping". Please let me know if I am right or wrong? Also let me know the solution for the same.
Regards,

Code is below:
ElementService.java (Web Service Code)
public class ElementService {
    public String echoService(String command, String data) {
        System.out.println("Echo Service [" + command + "] Data [" + Data + "]");      
        return "Success;
    public Object getDimeData(DataHandler dh) throws InputValidationException, AttachmentServiceException {
        MessageContext msgContext = MessageContext.getCurrentContext();
        Message rspmsg = msgContext.getResponseMessage();
        log.info("org.apache.axis.attachments.Attachments.SEND_TYPE_DIME : " + org.apache.axis.attachments.Attachments.SEND_TYPE_DIME);
        int inputAttachmentType = rspmsg.getAttachmentsImpl().getSendType();
        log.info("inputAttachmentType : " + inputAttachmentType);
        if (inputAttachmentType != Attachments.SEND_TYPE_DIME) {
            String failMsg = "Attachment passed is not a DIME attachment, please check.";
            throw new InputValidationException("Invalid input data error : " + failMsg);
        String inputStr = getInputString(dh);
        //Do some process with the input String and construct an output String.
        //Since the processing is out of context for our disucussion,
        //just an output xml String from a file is returned.
        String result = null;
        try {
            result = "Successfully Read the input file";
        } catch (IOException e) {
            String errorMsg = "Error occured while sending the output xml in DIME format.";
            log.error(errorMsg, e);
            throw new AttachmentServiceException(errorMsg, e);
        log.info("setting the DIME type of attachment as the sender sends it as DIME.");
        rspmsg.getAttachmentsImpl().setSendType(org.apache.axis.attachments.Attachments.SEND_TYPE_DIME);
        ByteArrayDataSource dataSource = new ByteArrayDataSource(result, "UTF-8");
        dh = new DataHandler(dataSource);
        return dh;

Answer 1

this isn't an axis forum, it is a java forum. you're probably better off asking this question in an axis specific forum.
that said, unless you are required to use axis for this project, i'd look into using JAX-WS. it is integrated into the jdk and much simpler (IMO) to use. plus, you'll get better help in these forums if you are using it.
