Embedded Java And BPEL

Question

Hi All
I need some very urgent help. I had been working on TIBCO and XI till now and in a project currently using Oracle Fusion. I need to query a data from an LDAP service and post a collection of employees into a JMS Queue as an XML. Now I tried using Embedded java to query the LDAP service and that works fine and it returns me the employee details. I have an XSD file that represents how the data needs to be presented. I imported the XSD file into my project and created a variable of element type and chose the schema to be the XSD which I am pasting below. I tried all kinds of ways to populate the data but I always get a selection failure error.
I then just tried a simple setVariableData method to set the username and again i get the same error. How can I set the variable so that it returns me a collection back. Please help. I am pasting both the XSD as well as the java code that I tried to use. It would be great if someone could let me know what I have done wrong or is there any ways of doing this.
Thanks so much

Java Code I have written
try
setVariableData("Variable_1","LDAPEmployeeCollection","/ns1:LDAPEmployee/ns1:UserId")
catch(Exception e)
setVariableData("Variable_2",e.toString());
addAuditTrailEntry(e);
}

Hi Marc
I tried what you had suggested but i always get a BPEL error stating a selection failure.
Im pasting my Java Code here with
try
java.util.Hashtable env = new java.util.Hashtable();
env.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(javax.naming.Context.PROVIDER_URL, "ldap://saturn:389");
env.put(javax.naming.Context.SECURITY_AUTHENTICATION, "simple");
env.put(javax.naming.Context.SECURITY_PRINCIPAL, "serenecorp\\rmohammed");
env.put(javax.naming.Context.SECURITY_CREDENTIALS, "s3r3n3!");
// Create initial context
javax.naming.directory.DirContext ctx = new javax.naming.directory.InitialDirContext(env);
//System.out.println(ctx.lookup("OU=Consultants,DC=serenecorp,DC=com "));
// Specify the ids of the attributes to return
String[] attrIDs = {"sn", "givenName", "mail", "createTimeStamp"};
javax.naming.directory.SearchControls ctrls = new javax.naming.directory.SearchControls();
ctrls.setReturningAttributes(attrIDs);
// Specify the attributes to match
//Attributes matchAttrs = new BasicAttributes(true);
//matchAttrs.put(new BasicAttribute("sAMAccountName", "jale*"));
String filter = "(&(sAMAccountName=*)(createTimeStamp>=20061116221624.0Z ))";
//matchAttrs.put(new BasicAttribute("createTimeStamp", "> 20061115221624.0Z"));
setVariableData("Variable_3","test2");
// Search for objects that have those matching attributes
//NamingEnumeration answer = ctx.search("OU=Consultants,DC=serenecorp,DC=com", matchAttrs, attrIDs);
javax.naming.NamingEnumeration answer = ctx.search("OU=Consultants,DC=serenecorp,DC=com", filter, ctrls);
javax.xml.parsers.DocumentBuilderFactory domFactory = null;
     javax.xml.parsers.DocumentBuilder domBuilder = null;
     domFactory = javax.xml.parsers.DocumentBuilderFactory.newInstance();
domBuilder = domFactory.newDocumentBuilder();
     org.w3c.dom.Document newDoc = domBuilder.newDocument();
     org.w3c.dom.Element rootElement = newDoc.createElement("LDAPEmployeeCollection");
rootElement.setAttributeNS("ns1","ns1","http://www.macerich.com/o2c");
newDoc.appendChild(rootElement);
while (answer.hasMore())
setVariableData("Variable_3","test3");
javax.naming.directory.SearchResult sr = (javax.naming.directory.SearchResult)answer.next();
System.out.println(">>>" + sr.getName());
          javax.naming.directory.Attributes attrs = sr.getAttributes();
if (attrs == null)
System.out.println("No attributes");
          else
org.w3c.dom.Element rowElement = newDoc.createElement("LDAPEmployeeType");
rowElement.setAttributeNS("ns1","ns1","http://www.macerich.com/o2c");
               /* Print each attribute */
               for (javax.naming.NamingEnumeration ae = attrs.getAll(); ae.hasMore();)
javax.naming.directory.Attribute attr = (javax.naming.directory.Attribute)ae.next();
String id =attr.getID().toString();
if(id.equals("sn"))
id = "UserId";
else if(id.equals("givenName"))
id ="firstName";
else if(id.equals("mail"))
id ="email";
else if(id.equals("createTimeStamp"))
id="effectiveStartDate";
System.out.println("attribute: " + attr.getID());
System.out.println("Value: " + attr.get());
org.w3c.dom.Element curElement = newDoc.createElement(id);
curElement.appendChild(newDoc.createTextNode(attr.get().toString()));
rowElement.appendChild(curElement);
setVariableData("Variable_3","test4");
rootElement.appendChild(rowElement);
// Print the answer
//printSearchEnumeration(answer);
javax.xml.transform.TransformerFactory tranFactory = javax.xml.transform.TransformerFactory.newInstance();
javax.xml.transform.Transformer aTransformer = tranFactory.newTransformer();
     javax.xml.transform.Source src = new javax.xml.transform.dom.DOMSource(newDoc);
javax.xml.transform.Result dest = new javax.xml.transform.stream.StreamResult(new java.io.File("c:/test.xml"));
aTransformer.transform(src, dest);
org.w3c.dom.NodeList nl = newDoc.getElementsByTagName("LDAPEmployeeCollection");
org.w3c.dom.Node nd = nl.item(0);
System.out.println("XML---"+rootElement.toString());
setVariableData("Variable_1","LDAPEmployeeCollection",newDoc);
// Close the context when we're done
ctx.close();
catch (Exception e)
setVariableData("Variable_3",e.toString());
addAuditTrailEntry(e);
I tried numerous things and today is the final day for my code completion. So i am in a bit of trouble. I just cant figure out what I have done wrong here. I have created a DOM document as you had suggested and then done a setVariableData onto the Variable_1 that i had created selecting the xsd that I had pasted in my previous post as the schema for the variable. I have the namespace set corretly as well. Any suggestions.
Thanks so much in advance
