lakh users who can hit our site for login(the connection
to the database). Database could be oracle or Ms-sql.
can any body help me here, what driver should i use
which can support connection pooling and how should be
the connection pool in my code.
a sample code is more helpful.
help is appreciated.
thanx.

your classpath.
U either include them in your CLASSPATH variable
or install them as extensions.

iam working with ejb on weblogic7.0
i have downloaded one small application from
http://weblogic.com/docs/examples/ejb/basic/containerManaged/index.html
and running on my system. I found problem while deploying
saying that Bean must implement the following methods
findByPrimaryKey()
findAccount()
findBigAccounts()
findOrderedBigAccounts()
findDescOrderedBigAccounts()
findNullAccounts()
but this bean has no implementation of this methods
where in the EJB Home interface they are declared.
what could be the reason for all such examples when
downloaded.
it could be more helpful if u just go to that url and have
a few minutes of refering that example.
else, just tell me to whom should i contact to get the
response from ?
please let me have that mail-id.

can any body please give me the code for
putting an image into database and retriving
it through jdbc using servlets and display that
image on to the browser.
iam using an html to send imagename and
using servlet to save it to database
and again want to retrive it through servlet
and display it on the browser.
thanx..

can anybody tell me how to set Initialisation parameters
in ejb-jar.xml in weblogic7.0 as i used in weblogic5.1
<env-entry>
<name>URL
<type>java.lang.String
<value>jdbc dbc:mydsn
</env-entry>
and retrived in my bean as
String url = initcontext.lookup
("java:comp/env/URL").toString();
it worked fine but if i edit ejb-jar.xml for setting
<env-entry> its saying thats not defined in dtd file
becuase ejb-jar.xml is created by the tool itself in
weblogic7.0
thanx..

how to edit ejb-jar.xml in weblogic7.0
which can be viewed in weblogic builder tool
but can we have any chance of edit that
because i want to use User Transaction in
stateful session bean for that i have to
set <trans-attribute>Never</trans-attribute>
<trans-type>container</trans-type>
help is appreciated.
with regards..

hello, i want to use User Transaction control in
Statefull Session Bean. So for that i need to change in
ejb-jar.xml in that under trans-attribute as below
<trans-attribute>Never</trans-attribute>
<trans-type> container </trans-type>
I do edit ejb-jar.xml in weblogic5.1. But how can
i change it in weblogic7.0 as the tool itself creating
those xml's . I can view those xml files under view tab
of weblogic builder. but how can i edit..??
its urgent please...
thanx.

Iam working with sample stateful session bean
can any body please reply me what could be the problem here in my client code below.

prop.put(Context.PROVIDER_URL,"t3://localhost:7001");
prop.put(Context.SECURITY_PRINCIPAL, "venu");
prop.put(Context.SECURITY_CREDENTIALS, "venuvenu");
Context ctx = new InitialContext(prop);
Object obj = ctx.lookup("banking");
banksfullHome home = (banksfullHome)PortableRemoteObject.narrow(obj,banksfullHome.class);
banksfullRemote br1 = (banksfullRemote)PortableRemoteObject.narrow(home.create(999),banksfullRemote.class);
banksfullRemote br2 = (banksfullRemote)PortableRemoteObject.narrow(home.create(888,"Shiva",3000.00),banksfullRemote.class);

System.out.println(br1.getBalance());
System.out.println(br2.getBalance());

.................
and my Home is
public interface banksfullHome extends EJBHome
{
public banksfullRemote create(int accNo) throws RemoteException,CreateException;
public banksfullRemote create(int accNo,String accName,double bal)throws RemoteException,CreateException;
}
