Oracle Team?? EJBean Problem on Oracle JVM

Question

Hi,
I am using Jdeveloper3.1 and Oracle8.1.6 for my application. I could deploy and run the EJB on Oracle JVM without any problems. But when I am trying to connect to the Database it is giving me the null value instead of 'Y' or 'N'. The same EJbean I used as the USEBEAN in JSP and it is giving me correct results. I tried to debug and I found it is not getting the connection.I am giving the example I tried.
1. EJB
package EJBSample;
import java.rmi.RemoteException;
import javax.ejb.*;
import java.sql.*;
public class ValidateBean implements SessionBean {
String UId;
String PWd;
Connection conn;
Statement st;
public ValidateBean() {
public void setUId(String UId) throws RemoteException {
this.UId=UId;
public void setPWd(String PWd) throws RemoteException {
this.PWd=PWd;
public String getUId() throws RemoteException {
return UId;
public String getPWd() throws RemoteException {
return PWd;
public String validate() throws RemoteException {
String flg = null,login = null,pass = null;
try{
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()); flg = "Before Conn..."; conn = DriverManager.getConnection("jdbc:oracle:thin:@pcgamingit4:1521:Everest","scott","tiger"); flg = "After Conn..."; st = conn.createStatement(); String str = "select * from CRM_WRK_LCTN where LOGINID='"+UId+"'"; ResultSet rs = st.executeQuery(str);
while(rs.next()){
login = (String) rs.getString("LOGINID");
if(login.equals(UId)){
pass = (String) rs.getString("PASSWORD");
break;
if( (UId.equals(login)) && (PWd.equals(pass)))
flg="Y";
else
flg="N";
st.close();
conn.close();
}catch(Exception e){ }
return flg;
public void ejbCreate() throws RemoteException, CreateException {
public void ejbActivate() throws RemoteException {
public void ejbPassivate() throws RemoteException {
public void ejbRemove() throws RemoteException {
public void setSessionContext(SessionContext ctx) throws RemoteException {
2. Client:
package EJBClient;
import java.sql.*;
import java.util.*;
import javax.naming.*;
import oracle.aurora.jndi.sess_iiop.*;
public class ValidateClient {
public static void main(String[] args) {
String ejbUrl = "sess_iiop://localhost:2481:Everest/test/Validate";
String username = "scott";
String password = "tiger";
// Setup the environment
Hashtable environment = new Hashtable();
// Tell JNDI to speak sess_iiop
environment.put(javax.naming.Context.URL_PKG_PREFIXES, "oracle.aurora.jndi");
// Tell sess_iiop who the user is
environment.put(Context.SECURITY_PRINCIPAL, username);
// Tell sess_iiop what the password is
environment.put(Context.SECURITY_CREDENTIALS, password);
// Tell sess_iiop to use credential authentication
environment.put(Context.SECURITY_AUTHENTICATION, ServiceCtx.NON_SSL_LOGIN);
// Lookup the URL
EJBSample.ValidateHome homeInterface = null;
try {
System.out.println("Creating an initial context");
Context ic = new InitialContext(environment);
System.out.println("Looking for the EJB published as 'test/Validate'");
homeInterface = (EJBSample.ValidateHome) ic.lookup(ejbUrl);
catch (ActivationException e) {
System.out.println("Unable to activate : " + e.getMessage());
e.printStackTrace();
System.exit(1);
catch (CommunicationException e) {
System.out.println("Unable to connect: " + ejbUrl);
e.printStackTrace();
System.exit(1);
catch (NamingException e) {
System.out.println("Exception occurred!");
System.out.println("Cause: This may be an unknown URL, or some" +
" classes required by the EJB are missing from your classpath.");
System.out.println("Suggestion: Check the components of the URL," +
" and make sure your project includes a library containing the" +
" EJB .jar files generated by the deployment utility.");
e.printStackTrace();
System.exit(1);
// That's it!
try {
System.out.println("Creating a new EJB instance");
EJBSample.Validate remoteInterface = homeInterface.create();
remoteInterface.setUId("mallik");
remoteInterface.setPWd("malli");
System.out.println("Calling EJBSample.Validate methods...\n");
// Method calls go here!
String str = remoteInterface.validate();
// e.g.
// System.out.println(remoteInterface.foo());
System.out.println("...done!");
System.out.println(str);
catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
3. Result:
EJBClient.ValidateClient
Creating an initial context
Looking for the EJB published as 'test/Validate'
Creating a new EJB instance
Calling EJBSample.Validate methods...
...done!
Before Conn...
Can you please tell me the problem. I have wasted 2 days on this.

Answer 1

You're running this EJB in iAS, right?
You have to grant JAVAUSERPRIV to the user running your EJBs so that it is allowed to open a JDBC Thin socket out of the JVM to the backend database.
