EJB and Poinbase database

can anybody knows how to connect the database (pointbase) with EJB(entity bean) ?????????

Simple, configure a datasource and lookup for it whenever you need to use a connection.

How to work with EJBs and database for a simple login application

Hi all :)
I am new in JSP,EJB and Servlets. I just wanted to develop a simple login application, using JSP+EJBand servlets. In some tutorial I found that the beans are already populatesd with database records. But will it be good logic to retrive all records into a bean and then search for a perticuler users data for authentication.
Can any one tell me me what is the best logic for doing so. :(
Thanx in advance.

Database connection with EJB and Sun Application Server

I have tried some tutorials from sun in Savings account eg some errors were
showing like primary key not found etc
please help me to link EJB application with database application

Debated: Primary Key requirement
Does a GOOD database require a PK? Yes.
Does EVERY database require a PK? Debated.
Your db table needs a primary key. The PK is how a table identifies unique records.

Problem with EJB and JMS - Failed to obtain/create connection

hello ejb and jms programmers,
My problem is my topic MDB keep on retrieving the same message when there is a database connection failure. Maybe somebody could help me how to prevent to retrieve the same data?
Given:
- I purposedly turn off the pointbase database because im testing my error handling.
- Im using SJSAS 8 as my application server.
- My message Driven Bean of topic type.
- Im using CMP for my entity bean
Here is the scenario of whats happening - step by step:
1. A separate application publishes a message to JMS queue server
2. My MDB retrieves this message and do some processing then inserts a record (transaction history) in my database
3. But my db is turned off or down
4. My MDB sends a successful processing reply to the JMS queue server
5. Then i noticed that my server.log keeps on growing so when i opened it, the record was not inserted and printed the stacktrace below "RAR5117 : Failed to obtain/create connection. Reason : javax.transaction.SystemException" (complete stacktrace below)
6. I understand the cause of the stacktrace is because the DB is turned off. But what i dont understand is that my MDB keeps on reading the same message. Since my MDB is of topic type, isnt a topic MDB supposedly reads a message only once???
So my questions are:
1. how do i handle insert database error?
2. how can i stop my MDB from processing the same message?
3. any better suggestions?
Thank you in advance :)

Hi annie,
Wherever you are handling database transactions,
you'd not be able to create a Connection if database
is closed (I think you mentioned turning off the
database) then at this condition, you should
certainly throw a System level exception and stop all
processing with some meaningful flow to indicate a
failure (like display message on UI). Even
network problems are handled by exceptions... so I
don't see a reason why you didn't wrap it in the
first place.
Anyway, try handling specific exceptions rather than
the general Exception... this will give you a better
idea of what to do in case of an exception.Yes i know this. I am practicing this in my non-j2ee server applications. But the j2ee app im making, i just pass the db url in the descriptor and the app server automatically creates the connection for my app. So where would i put exception handling?
2. how can i stop my MDB from processing the same
message?Guaranteed delivery is not supposed to stop
processing. It will continue to process the message
after certain intervals till the message is
delivered. You shouldn't deliver it at all, if you
are able to detect that the database is off
The problem here is that my MDB automatically retrieves the message from the JMS queue server. Im not the one retrieving the messages manually.
My assumed behavior of topic MDB is once the a certain MDB retrieves a message it will not retrieve the same message anymore.
thank you in advance.

How to pull data from EJB and present them using Swing ?

Hi all,
I've written stateful session bean which connect to Oracle database, and now I must write stand alone client application using Swing.
The client app must present the data and then let users add,delete and edit data and it must be flexible enough to iterate through the records.
The swing components can be JTextField,JTable etc.
How to pull the data from EJB and present them to users with the most efficient network trip ?
Thanks in advance
Setya

Thanks,
Since the whole app originally was client-server app and I want to make it more scalable, so I decide to separate business logic in the EJB but I also want to keep the performance and the userfriendliness of the original user interface, and I want to continue using Swing as the original user interface does.
I've read about using Rowset and I need some opinions about this from you guys who already have some experience with it.
Any suggestions would be greatly appreciated.
Thanks
Setya

EJB and Servlets

Hi there,
A frontend processing of HTTP request that pass thru WebLogic server that make
API calls thru tuxedo to the application servers that eventually running C, C++
that retrieve data from a backend database of Oracle.
Being the services of EJB and Servlets, EJB is more kind of processes inside the
server but Servlets can handle better in request and respond (talk to the client),
whats your opinions in this kind of integration? Go for pure EJB or Servlets?
Or shall mixed matched? and how should the architecture should looks like?
Thanks
Neo

Sorry, wrong question, just ignore it.

EJB and Tools

Hi there,
3 questions here:
First, does CMP can call stored procedure from a database? or BMP only? or both? Please show me some codes on whichever.
Secondly, can a session bean call a stored procedure? Any codes?
Last, does there any tools or IDE that have source codes control and works with WebLogic servers?
Thanks a lot
Neo

Some further explanation please...
1. What does these method doing inside my EJBean?
- ejbPassivate()As the name suggest this method helps in passivation... i.e. persistence of ejb state.
The container invokes this method on an instance when the container decides to disassociate
the instance from an entity object identity, and to put the instance back into the pool of avail-able
instances. The ejbPassivate() method gives the instance the chance to release any
resources that should not be held while the instance is in the pool. (These resources typically
had been allocated during the ejbActivate() method.)
For session beans in advanced cases, a session object�s conversational state may contain open resources, such as open sockets and open database cursors. A container cannot retain such open resources when a session bean instance is passivated. A developer of such a session bean must close and open the resources in the ejbPassivate and ejbActivate notifications.
- setSessionContext(SessionContext ctx), since my
my codes in the Remote interface does not call this
method which also passes a parameter ctx?setSessiontContext is invoked by container and the ctx required by it is supplied by container. Thus u dont require to pass ctx parameter.
The bean�s container calls the setSessionContext method to associate a session bean instance
with its context maintained by the container. Typically, a session bean instance retains its session context as part of its conversational state.
The context supplied by the container helps you to identify the poperties in deployment descriptor...i.e. your next question..
- Where does this referred in the EJBean ->
-> cntx.lookup("java:comp/env/jdbc/mydatabase");
where that i can see the reference to?
You can refer these statements any where u need to access database. Suppose you need to fire a procedure after you have created a record. You can write these statments in ejbPostCreate method.
2. Inside my ejb-jar.xml file, which is a deployment
descriptor, what are these tags meant?
- <env-entry>, <env-entry-name>, <env-entry-type>,
e>, <env-entry-value>
env-entry stands for environment entries. These are like env. variables which u need to access at runtime.
Each env-entry element describes a single environment entry. The env-entry element consists of
an optional description of the environment entry, the environment entry name relative to the
java:comp/env context, the expected Java type of the environment entry value (i.e., the type of the
object returned from the JNDI lookup method), and an optional environment entry value.
An environment entry is scoped to the enterprise bean whose declaration contains the env-entry ele-ment.
This means that the environment entry is inaccessible from other enterprise beans at runtime, and
that other enterprise beans may define env-entry elements with the same env-entry-name with-out
causing a name conflict.
The environment entry values may be one of the following Java types: String, Character, Inte-ger,
Boolean, Double, Byte, Short, Long, and Float.
If the Bean Provider provides a value for an environment entry using the env-entry-value ele-ment,
the value can be changed later by the Application Assembler or Deployer. The value must be a
string that is valid for the constructor of the specified type that takes a single String parameter, or for
java.lang.Character, a single character.
For example:
<env-entry>
<description>Return the developer of the bean</description>
<env-entry-name>author</env-entry-name>
<env-entry-type>java.lang.String</env-entry-type>
<env-entry-value>Neo</env-entry-value>
</env-entry>
Here description tag is optional.
<env-entry-name> specifies the property name, which in our case is author.
<env-entry-type> specifiest the data type of property, i.e String
<env-entry-value>The value for the property i.e Neo
You can imagine this as a java statement like
String author = Neo; //Return the developer of the bean.
TQ
NeoHope this explanation was helpful to u

Hi,
Which server r u using? I think u have not included the server jar file in u r classpath. for weblogic server, the look up should be like this.
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
p.put(Context.PROVIDER_URL,"t3://localhost:7001");
InitialContext ctx = new InitialContext(p);
Object obj = ctx.lookup("HelloBean");

EJB and access controll???

Hi all,
I have a question about access control via EJB,
For example I have a client app�ication and on start I will prompt user for user name and password, and now what to do with this information how to pas it to the ejb server, or??? Or may be some of you have any link to tutorial as an answer? My EJB will access database and I want to use the access control from database.
Thank you in advance.

Hi Eshwa,
thank you for your reply, I found a nice developer guide on the link that you give me, but I steal have a problem with undestanding of practical way to pas user information from client application to ejb server, may be you can give mi a pice of code or an small example, where is geted 2 String (user name and password) and sent to the ejb server to be autentificated, and then to have acces to the resources that is accessable for this user (discribed in the deployment description user - role).
Anyway thank you again.
Best regards Alexander Hincu .

EJB and ASP

Think of XSL and JSP as the X and Y axis. They approach solving an HTML (or
XML) rendering problem in two different ways. Each has its benefits. When
the primary input is a known flavor of XML, then XSL is definitely a better
way to go.

I think the best approach would be to use XML and XSL. I didn't work on itfor
production, but I'm going to try.
I would call EJB's from servlet, then put returns in one or more XMLfiles, then
take XSL and convert to anything, say HTML on the fly and send it back to
client's browser.
In this model web designer won't need to care about Java, JavaBeans andJSP tags,
he will get my XML definition and make a XSL.

\---JSP
All client requests are handled by servlets. Servlets perform the
brunt of Java work that would otherwise be in your JSP or a bean. The
servlets, of course, make calls to EJBs. The EJBs carry out all
business logic (e.g. talking to databases, legacy systems...). The
servlets then set attributes in the request and forward the request to
a JSP. The only responsibility the JSP has is presentation. We have
found this reduces the required Java in a JSP down to a manageable
subset that, in some cases, the HTML folks can handle. For instance,
enumerating through a Vector to populate a list box... It doesn't
always work this way, but most of the time.
If client requests first hit a JSP, I would certainly encourage you to
use JavaBeans in an effort to reduce the amount of Java in a JSP to a
manageable amount.

one more option:
in your JSP call servlets, and they will call EJBs and return java

(simple containers like struct in C/C++) with data.
in this case JSP will be your presentation layer, servlet - controllerand
EJBs - model. you may prefer to wrap all entity EJB calls in astateless
session beans, which will implement your business workflow.
example:
displayItems.jsp has a form with one text field "name" and a button
"search".
when you click a button, it will post a request to ItemListServlet. the
servlet takes "name" parameter, and calls a ItemHome.findByName(String
ItemName) method of Item session EJB. then it processes the returning
Collection, and puts an array with myItems[] into a session andredirects to
another page ItemList.jsp. now, ItemJsp takes an array and populates atable
on the screen. here myItems is a simple java class with public fields,like
C struct.
in this option, your servlets are kind of dispatchers between jsp andEJBs.

HELP! FOR LOOP TO SCROLL THROUGH TABLE AND CREATE DATABASE LINK

Hi,
Here's the scenario, not much of a PL programmer, just basic SQL so really need some help people!
I have 2 tables. 1 contains list of DB's and the other contains rules to follow.
I need to create a loop that goes through the table containing the DB's and on each row a DB link is created (Only 1 link allowed!)
Once created, the schema currently logged in with also has an account on the linked DB in order to run scripts- The scripts are stored centrally hence the requirement for the link to the target DB.
There are numerous scripts that need to be executed and can all be called from 1 script, once executed the loop exists and the database link needs to be dropped.
Once dropped, the first loop continues, creating a DB link for the next DB listed in the table (and all the scripts are fired again)
This continues against all the DB's listed in the table.

Hi BlueShadow,
Thanks again for the response, you've hit the nail on the head. SQL scripts on a unix server, a loop goes through a table 1 at a time. Each row gets a link created and then all the scripts stored on the server are executed against the db linked to. So I'm assuming this is a loop within a loop.
1 loop to go through the table to create the link and then another loop within once connected to execute all the scripts against the connected DB. Once the scripts are run, the loop exits and moves onto the next server and so on until all the servers have the scripts are run.
It's PL/SQL scripts we're after and not shell scripts as this would free us from the OS constraints.
We have to drop the links due to security. Any idea on o

Remote and local databases

let say that i access a oracle form through the web and that form access data from two distributed databases, then will there be a remote database and local database for the user or all the databases will be remote databases to the user

In my opinion.
using local databases -- access tables without DB_link
using Remote databases -- access tables through DB_link

Can EJB and BC exist at the same time in one project?

having to use ADF's BC and EJB to access data in both way due to the special requirements, but I am always getting the deployment failure.
can Ejbs and BC components exist at the same time in one project?

thanks for your reply.
I considered to separate the BC and EJB as the separate project. I just use the EJB component to implement the dynamic tree menu, whether a little make a mountain out of a molehill if you as a separate project.
