Question

im stuck in this terrible problem, I have a SOAP based webservice implemented in Java.The client besides other data is supposed to have “male” and “female” checkboxes so the user can either select one of them or both and the client is supposed to send it to the server to be stored in the database, where it is a multivalued entity, but it gives me Error 500, the failure on Server side, is the way i pass the array and then use it on server side correct? if not how could i pass and process it? here is the code for Client, Thanks in advance for your time:

private void salvaActionPerformed(java.awt.event.ActionEvent evt) {                                      
    // TODO add your handling code here:
    disease=malattia.getText();


    sexarra=new String[sexint];
    if(sexint==1)
        sexarra[0]=sexone;
    else if(sexint==0)
        JOptionPane.showMessageDialog(null, "Bisogna specificare almeno un valore del campo sesso", "Errore", JOptionPane.ERROR_MESSAGE);
    else{
        sexarra[0]=sexone;
        sexarra[1]=sextwo;}
        // System.out.print(sexarra[0]);
        //     System.out.println(sexarra[1]);



        description=descrizione.getText();


        agestr=eta.getText();
        if(agestr.equalsIgnoreCase(""))
            JOptionPane.showMessageDialog(null, "Il campo età non può essere vuoto", "Errore", JOptionPane.ERROR_MESSAGE);

        age=Integer.parseInt(agestr);
        if( age<=0 || age>=110){

            JOptionPane.showMessageDialog(null, "Il valore inserito nel campo età non è giusto", "Errore", JOptionPane.ERROR_MESSAGE);

Here is the Server Code:

    String ris = "no";
    String q = null, w = null;
    String errore = connetti();
    //inserimeto dei dati del utente dentro la tabella login
    if(sexarra.length == 2){
        q = "INSERT INTO malattia (nome, eta, descrizione, sesso) "
            + "VALUES ('" + malattia + "','" + eta + "','" + descrizione + "','" + sexarra[0] + "')";}
    else{
        q = "INSERT INTO malattia (nome, eta, descrizione, sesso) "
            + "VALUES ('" + malattia + "','" + eta + "','" + descrizione + "','" + sexarra[0] + "')";
        w="INSERT INTO malattia (nome, eta, descrizione, sesso) "
            + "VALUES ('" + malattia + "','" + eta + "','" + descrizione + "','" + sexarra[1] + "')";
    }

    if (errore.equals("")) {
        try {
            Statement st = conn.createStatement();
            if(sexarra.lenght == 2){
                st.executeUpdate(q);
                st.executeUpdate(w);
            }
            else
                st.executeUpdate(q);
            st.close();
            conn.close();
            ris = "si";
        } catch (SQLException e) {
            System.out.println("Errore: " + e.getMessage());
            return ris;
        }
    }   
    return ris;
}

This is last lines of Catalina.out it doesn’t make any sense to me.I suspect that the Array might be causing it since its determined at run-time, i couldn’t find any other way to do it, hints here will be appreciated

Unfortunately even after changing the code which i thought could be throwing NPE, it still hasnt changed anything. I changed from
if(sexarra[1]==null){….}

to
if(sexarra.lenght == 2){…}

I get the following error:

      Errore causata da: (SOAP-ENV:Protocol) :Unsupported response content type "text/html; charset=utf-8", must be: "text/xml". Response was:

Apache Tomcat/7.0.14 – Error report

Answer 1

I’m not sure I understand why you’re building SOAP requests by hand and not use some kind of automatic WSDL-to-class generator, one that comes with the JDK, Eclipse or NetBeans. This would give you type / structure safety, but I surely see problems in your code, for example

if(sexarra[1]== null) { ... }

could possibly throw a NPE or an ArrayIndexOutOfBoundsException. Unfortunately, Tomcat’s output does not make sense to me either, at least not towards your question.
