What i actually wanted to know is tht do i actually have to know wht to write the ejb using javadoc syntax meanin i have to memorize all the attribute names in order to write tht page.Also wanted to know wht is to be done after i write tht javadoc code.Just tell me the steps i dont need to know the indepth explanation.I do have ant installed.
sorry lasse wht i meant was not diff between entity bean and session bean writing to a database but session bean and bmp ejb coz in both u have to write code to access database.
And also i didnt get ur point regarding entity bean being used to view data rather than read/write data.If its not a problem could u pls provide me an explanation or link to a site where i could understand this better.

well so whats the diff between session bean and entity bean writing the data to a database.both require to have jdbc calls written in them
Hi,
Why i asked tht questions regarding ejb v/s servlets is because i have this one project where i have a transaction table where user payments are taken and 2 tables r updated.The no. of transactions basically depend on user payments in a day.It can be from 10-30 in a day.And data can be entered into the system by multiple users so wanted to know if its better to implement it using EJB or servlets.Also a user can view his transactions while the client is making updations to his account as someone has payed up the borrowed money from user
Also i have 3 entities in my system for which i enter data into a database system,one can edit,delete and view the info.A person can be viewing info while other may edit it.So is it better to use CMP ejb or just servlets.

if data can be written to a database using session beans and entity beans then why do we say tht entity beans represtn data in persistent storage mechanism.Coz session bean data is also stored in database.
1)How are threading issuues handled in ejb?
2)Does the container manage transactions for both cmp and bmp or transactions are to be coded for bmp?
3)What is the advantage of using ejb over servlets?
4)If i am to provide updations to a database,insertions and deletions in a multi user environment is it better to user servlets or beans .Why?

Hi ,
i got to update user info in database when the user enters his new info.So do i have to write a seperate query for updating in cmp and if i do then whts the point in cmp or is there a way out where by i can call the store() from the client side or update the database w/o writing a query bymyself.
Pls enlighten
Sorry guys i posted a wrong query my problem is with ejbStore() and no load actually i got to update user info in database when the user enters his new info.So do i have to write a seperate query for updating in cmp and if i do then whts the point in cmp or is there a way out where by i can call the store() from the client side or update the database w/o writing a query bymyself.
Hi,
I have this code where i am just loadin a row of data from the database table depending on the users input.Am using a cmp ejb and my query would be similar to the one generated form the ejbLoad() method so wht i would like to know is tht do i have to call a load() at the client side so tht the ejbLoad() get called and i can retrieve the value for the user to see or do i have to write a seperate function containing this query and then call the function.But if i do it its equivalent to writing a bmp ad i am writing the sql query myself.So pls can someone help me out.
Looks like im havin a tough time with ejb totally confused do guys pls help me out.
