ok thanks,
The xml schema that I used for generate the binding was http://www.opentravel.org/ and the software that I was integrate says be compatible with this standard... but I have this issue, anyway I make ugly quick fix, and now I will take next step this integration.

thanks!

Hi all,
I am begin work with xml, and I have a problem, I have the xml(Schema) :

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:pedido="http://www.alexflorentino.com/pedido"
targetNamespace="http://www.alexflorentino.com/pedido"
elementFormDefault="qualified">
<xs:element name="Pedido">
<xs:complexType>
<xs:sequence>
<xs:element name="Item" type="pedido:Item" />
<xs:element name="MessageType" type="pedido:MessageType" minOccurs="1" />
</xs:sequence>
<xs:attribute name="client_id" type="xs:int" use="required"/>
</xs:complexType>
</xs:element>
<xs:complexType name="MessageType">
<xs:annotation>
<xs:documentation xml:lang="en">If StartSeqNmbr and EndSeqNmbr are not sent, the request will be assumed to be for the last sequence number.</xs:documentation>
</xs:annotation>
<xs:sequence>
<xs:element name="MessageContent" type="xs:string" minOccurs="0">
<xs:annotation>
<xs:documentation xml:lang="en">This container is designed to store the response message.</xs:documentation>
</xs:annotation>
</xs:element>
</xs:sequence>
</xs:complexType>
<xs:complexType name="Item">
<xs:attribute name="produto_id" type="xs:int" use="required"/>
<xs:attribute name="quantidade" type="xs:int" use="required"/>
</xs:complexType>
</xs:schema>

and then I use xmlbeans for create the binding, and then I populate my java object, but when I transform the java object for xml format, I have some problem because some xml elements from MessageContent have xml entity for "<", ">".

and this is serious problem, because I need send this xml for third-part company, and them aren't be able handler this xml !

the full sample project(eclipse) can be found at : http://www.alexflorentino.com/help_xml.zip

any suggestion ?

very thanks,

Alex

Hard problem with tomcat 4.1 and jwsdp-1.3

Hi all,

I installed java jdk 1.4, tomcat 4.1 and jwsdp-1.3, it are configured and is working ok.

I create a servlet that handle SOAP messages, but it have strange result.

see my codes...

base servlet class

package test;
import java.io.IOException;
import java.io.OutputStream;
import java.util.Enumeration;

}
} catch (SOAPException ex) {
throw new ServletException("SOAPException: " + ex);
}
}

while (enum.hasMoreElements()) {
String headerName = (String)enum.nextElement();
String headerValue = request.getHeader(headerName);
StringTokenizer st = new StringTokenizer(headerValue, ",");
while (st.hasMoreTokens()) {
mimeHeaders.addHeader(headerName, st.nextToken().trim());
}
}
return mimeHeaders;
}

*/

if (i != 0) {
buffer.append(',');
}
buffer.append(headerValues[i]);
}
response.setHeader(headerName, buffer.toString());
}
}
}

my servlet

and finally my client test :

package test;
import java.io.File;
import java.io.IOException;
import java.io.StringReader;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPConnection;
import javax.xml.soap.SOAPConnectionFactory;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPMessage;
import org.apache.xmlbeans.XmlException;
import org.w3c.dom.Document;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import com.alexflorentino.pedido.PedidoDocument;
public class Test {
MessageFactory messageFactory;
public Test() throws SOAPException {
messageFactory = MessageFactory.newInstance();
}
public static void main(String[] args) throws XmlException,
IOException, UnsupportedOperationException, SOAPException {
try {
Test test = new Test();
test.soapClientSimpleMessage();
} catch(Exception ex) {
//System.out.println("exception:["+ex.getMessage()+"]");
ex.printStackTrace();
}
}
public void soapClientSimpleMessage() throws UnsupportedOperationException, SOAPException, ParserConfigurationException, SAXException, IOException, XmlException {
SOAPConnectionFactory connectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = connectionFactory.createConnection();
SOAPMessage message = messageFactory.createMessage();
SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
envelope.addNamespaceDeclaration("pedido", "http://www.alexflorentino.com/pedido");
SOAPBody body = envelope.getBody();
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
dbFactory.setNamespaceAware(true);
DocumentBuilder builder = dbFactory.newDocumentBuilder();
PedidoDocument pedidoDoc = PedidoDocument.Factory.parse(new File("conf/pedido.xml"));
Document document = builder.parse(new InputSource(new StringReader(pedidoDoc.toString())));
body.addDocument(document);
java.net.URL endpoint = new java.net.URL("http://localhost:8090/firstsoap/first2");
connection.call(message, endpoint);
connection.close();
}
}

I'm using tcpmonitor and it show :

but the tomcat says that message.getSOAPBody() is null , but it not seen correct because SOAPBody have content.

Somebody have some idea what is happening ?

thanks a lot
