Problem with getting Entity Beans refreshed within Session bean methods

Question

I hav following code in session and entity beans:
Session bean pseudo code: (PrimaryKey is primary key class for the entity
bean referred here, and MySessionHome is the home interfac class for this
session bean).
public class MySession implements SessionBean {
// This method is present in remote interface class as well.
public void methodA(PrimaryKey pk) {
// code to find entity bean by primary key specified.
update the entity bean, and mark it as isModified.
public void methodB(PrimaryKey pk) {
// code to find entity bean by primary key specified.
do something.
public void methodC() {
MySessionHome sessHome = code to lookup sessionhome from JNDI.
MySessionRI sess = sessHome.create(); // MySessionRI is the remote
interface class for MySession
PrimaryKey pk = new PrimaryKey(params);
sess.methodA(); // LINE ABC1
sess.methodB(); // LINE ABC2
all the entity and session bean methods have required as the TX attribute.
In methodB() on LINE ABC2, the entity bean obtained by findByPrimaryKey does
not reflect the changes made in call to methodA() on LINE ABC1.
Now if I change the LINE ABC1 and LINE ABC2 to
methodA(); // LINE ABC1
methodB(); // LINE ABC2
in this case the entity bean obtained in methodB() has the changes made in
methodA().
Any idea why this is happening?

Hi ad13217 and thanks for reply.
I'm sorry but my code is like this:
javax.naming.Context ctx=new javax.naming.InitialContext();
arguments was an error on copy, but it doesn't work.
Thanks
