Oracle Database Connection using JSP

I am attempting to create a simple web app using Oracle 9i and JSP. I am trying to create a connection to my database and do not seem to be having much luck. I have worked with ASP and can find my way around fairly well in that environment, however, JSP seems to be not as closely related as I initially thought. Can anyone point me to a good site that can give a beginner the basics on using this technology. I have been to several sites off of Oracle and Sun, but I seem to be more confused after reading them. With JSP, can I code as I would in ASP i.e JavaScript, etc? I have downloaded and installed the JDBC drivers from Oracle's website, but I receive errors when trying to establish a connection. If there is a site that can explain from the ground up how to set up a connection, I would be very greatful!

Hi,
This example uses Interbase, but hopefully you will find it useful anyway -

Problem in Oracle Database Connectivity in JSP

I am having big problem such as Oracle Database connectivity problem
Following code i am used for database connection. but it throw an exception call class not found exception.
Pls any one can help me. With a sample code for Oracle Database connection in JSP
Class.forName ("oracle.jdbc.driver.OracleDriver");
String url="jdbc:oracle:thin:@172.25.44.54:1521:bbo";
con = DriverManager.getConnection(url,"user", "user123");
Thank you

Well i've never used oracle or their drivers before but i'm presuming that you'd go to oracle.com or something and look for downloads. Otherwise you could goodle for Oracle JDBC drivers. Then just follow the instructions.
Again i've never used JSP but if you have a manifest file somewhere you'll need to put a class-path: entry in their referecning the jar file with the driver so that it is availble at run-time.

Checking Oracle Database availblity using JSP

Hello All,
How to check the database availablity using JSP like whether the TNS Listener is up or not, or the whole database is up or not.
Thanks
Rahul

Hi,
To see if your listener is up or down you can use the lsnrctl status, and to start use start option. You can make a similar operation for database, use the sqlplus program.
Another option is program a batch script, if you wan't use the commands.

Oracle database connectivity using oledb provider and atl classes in c++

dear friend ,
i m connecting oracle database in c++. i m using ATL classes and oledb provider for oracle. however i m facing some defficulties in stored procedure.
Normally MYSQL and sql server database is resulting result set in stored procedure i.e. we can use " select * from tablename" query in c++ to returning result. but in oracle we can not use this approch as because it dosent support. so how can i execute below stored procedure in c++ code. i have to retuen result set in STP. i m using SYS_REFCURSER in oracle . but how do i execute it in c++ code.
create PROCEDURE stp_getRecord ( p_curser SYS_REFCURSER) as
begin
open p_curser for select * from table_name;
end;
please help me asap.

I tried it, commented out the reader.read and have the following connection string
string connectionString = "provider=ORAOLEDB.ORACLE; data source=ORCL; password=****; user id=****; OLEDB.NET=True"
Unfortunately the result is the same.

Please help me resolve the problem
Thanks,

You should confirm that you can connect to the DB with a simple Java class using the url that the code you posted is using.
This will show that the OCI client is installed and executing properly. If you can't connect externally you will need to fix that first.
Is the Oracle client installed on the same machine the JDBC code is running on?

I definitely do not know much about JSP but

indicates
<quote>
This URL connects to the same database using the the OCI driver and the SID inst1 without specifying the username or password.

I do not see the port information in your connect string. Is that an issue?

Database locking using JSP and Oracle database

Dear All
I am reading about how to do database locking in general and i want to implement these mechanisms using JSP pages and oracle database, but i have the following questions:-
1.If i write a “select for update” quesry in the JSP page will it locks the record ? or it will not lock the record because the connection between the JSP pages and the server will be stateless in most online systems?
2.If i write all my jave code in transaction , something like this:-
• Begin transaction
• Commit or
• Rollback
Then should i be worried about the locking issues or the database manger will handle the locking mechanisms to insure data integrity(and what the default mechanism (if any) that the oracle database manger use to do the locking)?
3. If the answer for question 2 is no, then how can i handle the optimistic and the pentemistic locking using JSP pages?
BR

One way to solve this issue is as follows:
* You add a new column to each database table called 'version' which is of int type.
* Each time you alter any field in a record, you increament the version number.
* When you read a record and display it, you store the version number in your code
* when you go to update the record, you write your sql something like this:
update person set firstName=? where personId=? and version=?
Where the version is whatever you stored locally. If someone altered the record in the database while your
end user was looking at it, the version numbers will not match and the sql statement will
return zero as the number of records it altered. If its zero, inform the end user someone altered the record
while he was looking at it and weather or not he wants to proceed.
The chances of two people altering the same record in a table while both are logged in and viewing the same set of data is small so such collisions will be few.
You only need transactions if you are updating more than one record at a time (in the same table or multiple tables).
You dont need it for reading records if you use a single sql statement to read (for example: to join multiple tables).
In general, you get a (pooled) connection, use it, and close it as quickly as possible in a try/catch/finally block. You dont hold onto it for the duration of the user's session. A book on JDBC should help clarify this.

Jsp and database connection using bean

* I want create a bean to handle database connectivity.The
          <jsp:usebean> tag uses
          no argument constructor ..so I cannot pass the userid and password to
          the constructor.
          So how can I create a database connection when the user_id and password
          will be a part of parameter ?
          * Now I'm opening database connection in the jsp scriplets. Everytime I
          refresh the
          jsp page a new connection is created ? Is it not going to choke the
          database ? I cannot use connection pool because every user logs in with
          different userid.
          Thanks


You can pass your arguments in this way:
          <jsp:usebean id="myBean" scope="page"/>
          <jsp:setProperty name="myBean" property="userId", value=<%= user_id%>/>
          <jsp:setProperty name="myBean" property="password", value=<%=
          user_password%>/>
          of course, in your bean class, you should create two setter methods,
          setUserId and setPassword.
          Hopefully, this will help you.

I'd start by checking for a more recent driver version on Oracle's web site.
Or: googling for "createDMSSensors" (the "root cause" in the stack trace) has as the first hit: Re: Java Help Please! HttpServlet doFilter() Exception

when should you close the connection? when you're done with it.
how should you close the connection? like this: conn.close();
that said, doing this in a JSP page is bad form and not recommended
JSP's typically don't contain ANY business or data logic

How to create database connection using DB2Driver in JDeveloper 10.1.2.1.0?

I am trying to create a JDeveloper/Data Connection using com.oracle.ias.jdbc.db2.DB2Driver. The driver is registered from a User Libraries: DataDirect JDBC. I have the following class path for the library:
E:\DataDirect\3.4\lib\YMdb2.jar;E:\DataDirect\3.4\lib\YMbase.jar;E:\DataDirect\3.4\lib\YMutil.jar
I have no trouble configuring the connection but when I test it and I got No suitable driver Vendor code 0. Whats wrong? I have successfully created several database connections using Oracle thin driver. This is first time I am using a third party driver. Has any one successfully create a database connection using the com.oracle.ias.jdbc.db2.DB2Driver?

Hi
Since the error points to the unavailability of the driver class,can you double check your library claspath entries again.
I just tried a DB2 connection using the following properties and the connection went through fine:
Driver class name: com.oracle.ias.jdbc.db2.DB2Driver
URL: jdbc:merant:db2://<host_name>:50000;DatabaseName=SAMPLE

Jacky,
You need do the following for oracle type4 driver:
1) register the driver:
$IAS_HOME/bin/jdbcsetup
Driver Identifier: Oracle_Type4_816 (whatever name you like)
Driver Classname: oracle.jdbc.driver.OracleDriver
Driver Classpath: .../classes12.zip (install this this zip file somewhere
and add this zip into the Classpath later).
2) DataSource Setup:
start iAS Administration Tool (iASAT)
Choose Database, unfold iAS1 (your app server instance),
choose External JDBC Datasource -> add: DataSource Registration
JNDI Name: yourPoolName
Driver Type: Oracle_Type4_816 (select what you just register)
DataSource Url: jdbc:oracle:thin:@hostName:portName:dbName
Username: your_user_name
Password: your_passwd
(Datasource Pool: using defaults for now): you can also customrize the
parameters for the pool.
3. Add classes12.zip into CLASSPATH.
In your application, you can use JNDI lookup to get the DataSource from
which you get the connection from the pool.
Hope this helps.
Good luck.
