Help on creating Java Classes from WSDL in JDev 10.1.3

Question

Hi all,
I am creating Java Web Service Class in JDev 10.1.3 based on my WSDL file, but I am getting a JAVA class for each Element in my WSDL, and each class has its own methods. But what I need is to have Only ONE Class with the Elements wrapped as methods in this class (this is the result I had when I was using JDev 9.0.2 but I had Datatype conversion issue, so now I am trying to do the same with JDev 10.1.3)
My WSDL file is as follows:
- <s:schema elementFormDefault="qualified" targetNamespace="http://tempuri.org/">
- <s:element name="Connect">
<s:complexType />
</s:element>
- <s:element name="ConnectResponse">
<s:complexType />
</s:element>
- <s:element name="Disconnect">
<s:complexType />
</s:element>
- <s:element name="DisconnectResponse">
<s:complexType />
</s:element>
- <s:element name="GetPIValue">
- <s:complexType>
- <s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="piTAG" type="s:string" />
<s:element minOccurs="0" maxOccurs="1" name="piTS" type="s:string" />
</s:sequence>
</s:complexType>
</s:element>
- <s:element name="GetPIValueResponse">
- <s:complexType>
- <s:sequence>
<s:element minOccurs="1" maxOccurs="1" name="GetPIValueResult" type="s:double" />
</s:sequence>
</s:complexType>
</s:element>
<s:element name="double" type="s:double" />
</s:schema>
When creating the JAVA Classes in JDev, I am getting the following:
Connect.java
ConnectResponse.java
Disconnect.java
DisconnectResponse.java
GetPIValue.java
GetPIValueResponse.java
But what I actually need is to have a Method GetPiValue that should take in 2 paramters as strings and return a Double Value. Now the GetPIValue looks like this:
package ConnecttoPI;
public class GetPIValue implements java.io.Serializable {
protected java.lang.String piTAG;
protected java.lang.String piTS;
public GetPIValue() {
public java.lang.String getPiTAG() {
return piTAG;
public void setPiTAG(java.lang.String piTAG) {
this.piTAG = piTAG;
public java.lang.String getPiTS() {
return piTS;
public void setPiTS(java.lang.String piTS) {
this.piTS = piTS;
With this class Generated, how can I call the Class Methods and get the response?
Do I have to change the way/settings when I am creating the Java Classes using the Wizard? Why is the Wrapper wrapping the WSDL in multiple classes?
Thanks to anyone's help in advance.

An update to my previous Post:
After creating the Web Service proxy based on my WSDL file, I tested the Web Service Call from the Java Class (Service1SoapClient) and it is properly Calling the Web Service passing in String Paramters (2 Strings) and returning a Double Datatype. The Class is as below:
package project1.proxy;
import oracle.webservices.transport.ClientTransport;
import oracle.webservices.OracleStub;
import javax.xml.rpc.ServiceFactory;
import javax.xml.rpc.Stub;
public class Service1SoapClient {
private project1.proxy.Service1Soap _port;
public Service1SoapClient() throws Exception {
ServiceFactory factory = ServiceFactory.newInstance();
_port = ((project1.proxy.Service1)factory.loadService(project1.proxy.Service1.class)).getService1Soap();
* @param args
public static void main(String[] args) {
try {
project1.proxy.Service1SoapClient myPort = new project1.proxy.Service1SoapClient();
System.out.println("calling " + myPort.getEndpoint());
// Add your own code here
double testResponse = myPort.getPIValue("A3LI004.pv", "9/9/2007 9:20 am");
System.out.println("response from PI " + testResponse);
} catch (Exception ex) {
ex.printStackTrace();
* delegate all operations to the underlying implementation class.
Connect to PI Server
public void connect() throws java.rmi.RemoteException {
_port.connect();
Disconnect from PI Server
public void disconnect() throws java.rmi.RemoteException {
_port.disconnect();
Retrieve PI Values
public double getPIValue(String piTAG, String piTS) throws java.rmi.RemoteException {
return _port.getPIValue(piTAG, piTS);
Now I am trying to IMPORT this class into Oracle Forms, but I am getting the following Error:
Importing Class project1.proxy.Service1SoapClient...
Exception occurred: java.lang.NoClassDefFoundError: oracle/webservices/transport/ClientTransport
First, is this the Correct Class that should be Imported into Oracle Forms in order to Trigger the Java Class to Call the Web Service? Why am I getting this Error? I have read that this could be because of my CLASSPATH environment variable or the J2SE version compiling the java class???
Can someone help me to IMPORT this Java Class properly into Oracle Forms and Call the Web Service?
Many thanks for your help,
