Hi,
i modify JBoss3.0.2's source for speed up the creating of relationship and it seem work...


code is like:
org.jboss.ejb.plugins.cmp.jdbc.bridge.JDBCCMRFieldBridge
{
public void addRelation(EntityEnterpriseContext myCtx,
Object fk) {
...

FieldState tempFieldState = getFieldState(myCtx);//########Rich's modify
if(tempFieldState.isLoaded())//########Rich's modify
{//############Rich's modify
load(myCtx);
FieldState fieldState = getFieldState(myCtx);

// Check that .....
if(isSingleValued() && fieldState.getValue().size()
> 0) {
throw new IllegalStateException("This ...");
}

// must check to avoid dupes in the list
if(fieldState.getValue().contains(fk)) {
// we are already related to this entity
return;
}

// add to current related set
fieldState.getValue().add(fk);
}//#####################Rich's modify

// set the foreign key, if we have one.
if(hasForeignKey()) {
setForeignKey(myCtx, fk);
}
}
}

My modification is due to that JBoss is too slow when i add detail to a master which already have a lot of details.
I dont need iterator the details in my creating transaction
but JBoss will create the primarykey's Collection of all detail (maybe for synchronism)
it take too much time

so i modify the source
In addRelation i will check relation collection isLoad()
if not i dont need to add the collection again
just set the foreign key

i dont know if this is right
have anyone give some reply or suggest..
Thanks


Rich
PS.there is same problem in deleting Detail, i am trying to modify now...
