[jboss-user] [JBoss Cache: Core Edition] - JBosscache dirty read even though isolation is REPEATABLE_RE
I'm trying to evaluate the JBossCache for our application
I'm getting dirty read even though I rollback transaction. I tried this with EJB3
Stateless session bean BMT.
Could you please anyone help me on this prolbem, Am I making anything wrong?
Here is the code
public class TestEntity {
private int array[] = new int[100000];
public void update(int value) {
for (int i = 0; i < array.length; i++) {
array [ i ]=value;
}
}
public int[] getArray() {
return array;
}
}
Stateless Bean code to update cache
Stateless Bean 1
public void updateArray(int value) {
TransactionManager tm =
cache.getConfiguration().getRuntimeConfig().getTransactionManager();
try {
tm.begin();
String key = node.getFqn().toString();
TestEntity t = (TestEntity) node.get(key);
if(t != null) {
t.update(value);
node.put(key, t);
}
tm.rollback();
} catch (Exception e) {
try {
tm.rollback();
}catch(Exception ex1) {
ex1.printStackTrace();
}
e.printStackTrace();
}
}
Stateless Bean 2 to read and validating array
public boolean validateArray() {
TransactionManager tm =
cache.getConfiguration().getRuntimeConfig().getTransactionManager();
try {
tm.begin();
cache.getInvocationContext().getOptionOverrides().setForceWriteLock(true);
int a[] = readArray();
int value = a[0];
for (int i = 0; i < a.length; i++) {
if(a != value) {
System.out.println(a+":"+value);
sctx.getUserTransaction().rollback();
return false;
}
}
tm.commit();
}catch(Exception ex) {
try {
tm.rollback();
}catch(Exception ex1) {
ex1.printStackTrace();
}
ex.printStackTrace();
}
return true;
}
Configuration file:
I have used configuration file example for cache configuration
