Title: Message
Hi Saroj,
I am again here with the same problem. I replied
late because of some other office tasks. I have tried the changes that u have
mentioned but no luck, I got the same reply from jboss :(. There is another
message in this thread from Ooi Leng Chai [EMAIL PROTECTED].
probably u have gone through his mail. So what should I try next. I gona try
jboss 3.1. But I want 2.4.6 as our application is working smoothly over 2.4.6
except this remove problem.
waiting for your reply.
Thanks again,
Nayyer Kamran

illegalArgumentException while removing the entity bean
Hi
Kamran,
I
would like to point out something regarding use of remove() method on
EJBHome/EJBObject.
EJBObject : No need to use Handle here.
I think that you are not using this method. It seems that you are
calling EJBHome.remove();
EJBHomeObject: There are 2 ways to remove.
1) Use PK . home.remove(pk) - I
generally use this or EJBObject.remove()
2)home.remove(handle)
Observation: Mostly It looks fine to me except one
small suggestion.
Suggestion: Instead of using this for EQUALS check ,
try the following :
EXISTING CODE
**
public boolean equals(Object
obj) { if
(this.getClass().equals(obj.getClass()))
{
ApplicationPK that = (ApplicationPK)
obj;
return this.appID.intValue() ==
that.appID.intValue();
} return
false; }
SUGGESTED CODE
***
public boolean equals(Object
obj){boolean
retVal = false;
if ( obj instanceof ApplicationPK
){ApplicationPK
pk = (AddressPK) obj;
retVal = this.appID.intValue() == pk.appID.intValue();}return
retVal;}
EXISTINGCODE
**
public
ApplicationPK() { appID = new
Integer(0); }
SUGGESTED CODE
**
public ApplicationPK()
{
}
I think this should solve the
problem.

Thanks for your reply the Jboss version I am using
is 2.4.6 the tomcat 4.0.3, jdk is 1.4. I am attaching the code of the home,
remote, bean and primary key classes, deployment descriptor and pasting it in
mail too the exception is also there at the bottom as u can see in client code I
first find the remote obj through fBPK then access the bean remote method so far
so good then I call remove over remote booom here is the exception occures that
I pasted in the bottom. I have also added the table script so now I think every
thing is here to check it out.
I am waiting for thesolution, specilly from u

[JBoss-user] illegalArgumentException while removing the entity
bean
Dear Fellows,
I have an entity bean and its primary key is
java.lang.Integer I created a record through it, it works fine. Then I tried
to remove it by calling findByPrimaryKey(java.lang.Integer) it works
fine.
but when I made my own class asprimarykey
class(in new entity bean over the same table) and then Problem arises when I
tried to remove the entity bean it throws IllegalArgumentException. The
problem most probably in jaws but what should i do to remove it.
The exception stacktrace is given below. Any help
will be appreciated. it too urgent.
