Hi All,
I am facing problem to lookup a Stateless Session Bean having Local Interface From a CMP EntityBean i am Using WASD50.
===Here is the code====
This is UUID Bean Which Just generates UUID
package com.wesra.uuid;
import java.net.InetAddress;
import java.security.SecureRandom;
import com.wesra.ejb.exception.*;
/**
* Bean implementation class for Enterprise Bean: UUID
*/
public class UUIDBean implements javax.ejb.SessionBean {
private javax.ejb.SessionContext mySessionCtx;
//Non reapting random seed
SecureRandom seeder;
//cached value for mid part of string
private String midValue;

/**
* getSessionContext
*/
public javax.ejb.SessionContext getSessionContext() {
return mySessionCtx;
}
/**
* setSessionContext
*/
public void setSessionContext(javax.ejb.SessionContext ctx) {
mySessionCtx = ctx;
}
/**
* ejbCreate
*/
public void ejbCreate() throws javax.ejb.CreateException {
try {
StringBuffer stringbuffer = new StringBuffer();
seeder = new SecureRandom();
//Get the internet address
InetAddress inet = InetAddress.getLocalHost();
byte[] bytes = inet.getAddress();
String hexInetAddress = hexFormat(getInt(bytes),8);
//get the hex code for this object.
String thisHashCode = hexFormat(System.identityHashCode(this),8);

stringbuffer.append("-");
stringbuffer.append(hexInetAddress.substring(0, 4));
stringbuffer.append("-");
stringbuffer.append(hexInetAddress.substring(4));
stringbuffer.append("-");
stringbuffer.append(thisHashCode.substring(0, 4));
stringbuffer.append("-");
stringbuffer.append(thisHashCode.substring(4));
midValue = stringbuffer.toString();

}catch(Exception e) {
throw new UUIDCreateException("Fail to genereate UUID:"+e);
}
}
/**
* ejbActivate
*/
public void ejbActivate() {
}
/**
* ejbPassivate
*/
public void ejbPassivate() {
}
/**
* ejbRemove
*/
public void ejbRemove() {
}

//Developer Defined Methods
/**
* Implementation of method declared in Local
* interface
*/
public String getUUID() {
return getVal(midValue);
}

/**
* This is utility method for converting bytes into integer.
*/
private int getInt(byte abyte0[])
{
int i = 0;
int j = 24;
for(int k = 0; j >= 0; k++)
{
int l = abyte0[k] & 0xff;
i += l << j;
j -= 8;
}
return i;
}
/**
* This is utility method to convert integer primitive to hex format
*/
private String hexFormat(int i, int j)
{
String s = Integer.toHexString(i);
return padHex(s, j) + s;
}
/**
* This is utility method used for converting to hex format
*/
private String padHex(String s, int i)
{
StringBuffer stringbuffer = new StringBuffer();
if(s.length() < i)
{
for(int j = 0; j < i - s.length(); j++)
stringbuffer.append("0");
}
return stringbuffer.toString();
}
/**
* This is utility method for converting string to hex format.
*/
private String getVal(String s) {
long l = System.currentTimeMillis();
int i = (int)l & 0xffffffff;
int j = seeder.nextInt();
return hexFormat(i, 8) + s + hexFormat(j, 8);
}
}

Any Help in this is highly apperciated....
