Problem testing WebMethod. Throwing javax.xml.bind.JAXBException

Question

Hi guys,
Another Newbie.
Specifications:
NetBeans5.5
Sun App Server 9.0_01 (build b02-p01)
MySQL
Problem: Not able to test run the Webmethod with webparams.
I have an entity class with some methods as shown below
public class Country {
    private Integer countryID;
    private ServerDatabaseInteraction di;
    private String countryName;
    /** Creates a new instance of Country */
    public Country(ServerDatabaseInteraction di) {
        this.di = di;
     * Creates a new instance of Country with the specified values.
     * @param countryID the countryID of the Country
    public Country(Integer countryID) {
        this.countryID = countryID;
     * Creates a new instance of Country with the specified values.
     * @param countryID the countryID of the Country
     * @param countryName the countryName of the Country
    public Country(Integer countryID, String countryName, ServerDatabaseInteraction di) {
        this.di = di;
        this.countryID = countryID;
        this.countryName = countryName;
     * Gets the countryID of this Country.
     * @return the countryID
    public Integer getCountryID() {
        return this.countryID;
     * Sets the countryID of this Country to the specified value.
     * @param countryID the new countryID
    public void setCountryID(Integer countryID) {
        this.countryID = countryID;
     * Gets the countryName of this Country.
     * @return the countryName
    public String getCountryName() {
        return this.countryName;
     * Sets the countryName of this Country to the specified value.
     * @param countryName the new countryName
    public void setCountryName(String countryName) {
        this.countryName = countryName;
    public void insert() throws SQLException {
        di.update("INSERT INTO Country (CountryName) VALUES ('"+getCountryName()+"')");
    public ArrayList list() throws SQLException {
        ArrayList queryAL = new ArrayList();
        ResultSet rs = di.queryToResultSet("SELECT CountryID, CountryName FROM Country");
        while(rs.next()) {
            String temp = rs.getInt(1)+"#"+rs.getString(2);
            queryAL.add(temp);
         return queryAL;
}    then I created a Web service having two methods as follows
@WebService
public class CountryWS {
    ServerDatabaseInteraction di;
    Country country;
    public CountryWS() {
        try {
            di = new ServerDatabaseInteraction();
        } catch (Exception ex) {
            ex.printStackTrace();
        country = new Country(di);
     * Web service operation
    @WebMethod
    public ArrayList listPKobjects() {
        try {
            return country.list();
        } catch (SQLException ex) {
            ex.printStackTrace();
            return null;
     * Web service operation
    @WebMethod
    public String insert(@WebParam(name = "CountryName") String CountryName) {
        // TODO implement operation
        country.setCountryName(CountryName);
        try {
            country.insert();
            return "Inserted";
        } catch (SQLException ex) {
            ex.printStackTrace();
            return "Insert Failed";
}Now the problem is Im able to test (by right clicking on webservice from IDE) the webmethod listPKObjects but not the insert method. only difference is the second one is having webparms.
the log shows as follows..

Any help would be much appriciated.

Answer 1

I'm encountering the same problem, but it's very inconsistent. I've got three web services that I'm deploying. If I clean, rebuild, and redeploy, then different combinations of the three throw this error.
My specifications:
NetBeans 6.0
GlassFish v2
Oracle 10g
In browsing around online, I came across the following link which suggested to me that this issue is known and is being addressed.
https://jax-ws.dev.java.net/issues/show_bug.cgi?id=419
I discovered that the reason that I was getting this error was because my web services all had the same operation names. When I renamed my operations in each service so that they had different names, this fixed the problem.
Hope this helps!
