Connection to the Database thru Servlet

Hello:
I have just read some threads in this forum and noticed that people saying that connecting to the database in JSP is not a good Java Programming Habit. So, could you please give a little guidance on connection to the Oracle database in servlet. Thank you very much.
Oscar.

You use standard JDBC:
http://java.sun.com/docs/books/tutorial/jdbc/index.htmlIn a servlet container, most of the time, you set up a connection pool that you access through JNDI
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.htmlFor larger applications you might want to use "Data Access Objects"

Problem with EM (Enterprise Manager is not able to connect to the database)

Hi all,
I've Oracle DB 11g Rel.1 installed on Windows XP SP3. The database is up and running i.e. everyone can connect to the DB by using any App tool e.g. SQL*Plus, Forms, or Reports. It means that the listener and the service is running. But the problem is that when I try to start the EM I see some error messages on the webpage.
It says:
Enterprise Manager is not able to connect to the database instance. The state of the components are listed below.Database Instance (Green arrow)

please see the attached file:
http://rapidshare.com/files/404840300/em.JPGI've already checked all the services, they are running. And when I execute emctl command I got the following message.
emctl status dbconsole

http://shiman:1158/em/console/aboutApplication
Oracle Enterprise Manager 11g is running.I have checked some documents around config files in sysman and test_orcl\sysman directories. Moreover, I have checked dbsnmp and sysman account for unlockness and password accuracy. But they did not help me to solve the problem.
My question is if every thing is working fine then what is the problem with the EM? Why it is not connecting to the DB?
Thanks.
Iman

Enterprice manager is not able to connect to the database instance

hello,
I have problem with EM. I have some databases, and I worked with Enterprice Manager on this databases. First DB when I have repository is ok and EM always connect with this, but I worked on another DB some time and was ok, but three days ago when I start EM I get message 'Enterprice Manager is not able to connect to the database instance'. When I couldn't resolve this problem, I make new DB and this worked two days ok, and today I get this same message. I don't make any changes in listener and tns files.
any idea?

Don't say password is correct, if password is correct then tell us what last changes you did. did you change SYSMAN password throught alter user ...identified ... ?

Connection to the database

I have a page that contains a task menu. The links of some of the tasks leaves me to a jsp page. The bean associated to the loaded page connects to the database to load the dynamic data.
My questions are: each time someone loads the jsp page, a connection to the database is established? Where do I have to close the connection?
Is this a good solution or is it better to use a servlet that in its init method establishes the connection, and then pass this connection to the bean? If I use a servlet the action of the taks menu will have to call the servlet and then this will have to redirect to the correct jsp page. Am I right?
Where can I find a good example that helps me decide when to use a servlet or when to use a jsp page?
Thanks for your comments and help

The links of some of the tasks lead you to jsp pages. From each of those jsp pages call a servlet (keep only 1 common servlet).
This servlet would determine the request type (i.e. from which of the jsp pages the request is coming from). Based on the request type the servlet would perform the operations.
Write a class say, CreateConnectionHelper that creates the connection.
The servlet will call this class whenever it needs to create a connection.
After you create a connection perform the database operations and close the connection.

Connection to the database and session

Friends I am developing a JSP based application ,and I am storing Connection (to the database) info in a session variable in my main menu , and then I retrieve the connection session in all the pages that I navigate to.
But a friend of mine told me it is not a good programming practice.He adviced me to use the connection pooling to make effecient use of the connection.
So using session for storing connection to the database is a bad idea ?
I thought it is bad idea to get connected to the database everytime a jsp is thrown ...hence I was using session variable.
Please give ur thought about this.
Thanks.

Well.
You are using a kind of connection pooling already, since you make a connection and reuse it along every jsp page in a session but reusability is at the cut&paste level here.
And what would you do if you needed to share a connection between sessions (scope:application)
Or how would you resolve the need to connect to 2 databases in one JSP page ?? Duplicate the code from the "main menu" ?
If you have let's say 5 applications written as you described and the connection data (ip address, SID, host) changes as someone moves the database to another machine (for example :-))) you will have to manually correct all 5 applications. So it's not much of flexibility in this kind of code.
Connection pooling as I understood it (I might be wrong :-))) is placing the code in a bean or servlet and the parameters in a txt (or better xml) file so when something changes you don't rewrite applications, just rewrite one txt (xml) file and you are done.
If you use a connection pool as a bean you have the bean scopes you can choose from and so on.....
Visit
http://www.codestudio.com/index.shtml
for an example of a very well written connection pool. Maybe there you will find other issues to help you decide.
Hope this helps!

Avoid users to login into the database thru SQLPlus

I'm trying to use the after logon trigger described below, to avoid users to login into the database thru SQLPlus, user can only connect from from pls help me

If your only concern is preventing users from logging in via SQL*Plus, you could use the PRODUCT_USER_PROFILE table.
However, and this is a big however, this will not prevent users from logging in using any other tool (SQL Developer, SQL Programmer, TOAD, etc) if they know the Oracle user name and password. You can create a login trigger that generates an exception if the program that the client reports is connecting isn't on a list of valid products, but this sort of thing is easily circumvented just by renaming the executable on the client machine.
Fundamentally, if you have given a person an Oracle user name and an Oracle password, whatever privileges are available to the Oracle account are available to that individual. No matter what tool that person uses to connect to the database, they are going to have the same privileges. That's why you ideally want to restrict what users can do to the point that you don't care what tool they're using. Barring that, you can enable auditing and let the users know what they are and are not allowed to do by policy and use the audit logs to ensure compliance.

Itext connect to the database and put values in a table

Hi, I have a problem because I can't find any tutorial that would connect to the database using the itext servlet and then update the table. I have found a source code that is transferring the database items on the list package of itext. I need an example that is dynamically creating a table. Can anyone please help me with these problem. I need it to for my reports or could anyone suggest an easy to use library rather than itext. THANKS

tr3k wrote:
Guys, need your help...I just want to populate a resultSet on an itext table.I don't know what it means to "populate a ResultSet on an iText table". I guess the tool you are using to translate your question to English isn't very good.
Does it mean you have an iText table (whatever that is) and you want to create a ResultSet that allows you to extract data from it? Or do you really have a table in your database, and you want to use a ResultSet based on that table to create something in iText? Or what?

Hi,
From the 10.1.2 BI Beans Install Guide it says:
OracleBI Beans supports data stored in Oracle9i Enterprise Edition or Oracle Database 10g Enterprise Edition. However, only particular releases and patchsets are supported:
* Oracle9i Release 2 Enterprise Edition, as follows:
o 9.2.0.6 for all platforms.
o 9.2.0.5 with the latest OLAP patch for Windows-only.
* Oracle Database 10g Release 1 Enterprise Edition with the latest OLAP patch.
From the error message it would appear that the Database is not one of the above.
Thanks,
Lisa

Hi,
Please note that we have follwing versions of DB up and running:-
1)Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options
2)Oracle9i Enterprise Edition Release 9.2.0.5.0 - Production
With the Partitioning and Real Application Clusters options
JServer Release 9.2.0.5.0 - Production
Pls let us know the solution to resolve this problem ASAP.
Thanks.

You are not using a supported version of the database. BI Beans/OLAP only support the following database versions:
10g - 10.1.0.3 with additional OLAP patch
9i - 9205 with additional OLAP patch
9i - 9206
I would suggest that you have not applied all the required database patches to your instance.
Hope this helps
