Sharing Portal database connection with JSP page

Hi out there,
I implemented a JSP page as a selection form to be integrated into Oracle Portal. This JSP page contains a 'dynamic' form which needs to send queries to the database also integrated in the Portal.
For this I am currently using a JDBC connection but I would prefer to use the internal db connection of the Portal System.
Explanation: The user has to log in to the Portal and after that can call the JSP form. To poulate some comboboxes within this form I need some data from the database and the user does have READING privileges on that database.
Can anybody tell me how to use the user's login and password (or the established connection) to fetch the needed data from the database OTHER than with a jdbc connection?
Thanx in advance!
Cheers,
Thomas

sorry. not going to happen. you're running in a completely different environment when running Java on Portal. Portal is running in the database; your Java is running on the application server. your Java code must use JDBC to access any database resources, even if Portal related.
it is essential that you implement a connection pool on the application server to optimize your database traffic. check out bitmechanic for a very good open source option.
good luck,
rich

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

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.

Database connectivity in JSP

Hi all,
i am new to JSP and first time trying this code.i am trying to make a connection with the database,there is some problem in SQL.it show me SQLException.
Here is code connec.jsp:
<%@ page import="java.sql.*" %>
<% String name = request.getParameter("name");
String age = request.getParameter("age");
%>
<%
Connection conn = null;
Statement stmt = null;
     PreparedStatement pstmt = null;
ResultSet rs = null;
     try {
          Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
          conn = DriverManager.getConnection ("jdbc:odbc:unsoda_project","project_unsoda","project");
     }catch (Exception e) {
          out.println(e);
%>

<TABLE>
<%
     try {
          stmt = conn.createStatement();
          rs = stmt.executeQuery("Select codes from code_filter where codes > 1020");
          while(rs.next()) {

%>

%>
When i tried to see the output through web browser it show me Exception:
/*java.sql.SQLException: [Microsoft][ODBC driver for Oracle][Oracle]ORA-00913: too many values */
Now pls. tell me how do i do this connectivity and can diaplay the output of the query into the combo box.
Thank you,
sonika

which of your catch blocks is throwing the exception. From the looks of the message, the ODBC driver is having and argument with the oracle driver based on your query. It says it is wrong. You shouldn't get the error about parameters if your driver doesn't connect, so I don't think that's the problem, I think it is your query.

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 -

SQL Server Database Connectivity with Visual Studio 2012 - Help Needed

Hello,
I am having Visual Studio 2012 and SQL Developer 4.0 installed on my system with Windows 8 - 64bit
I want to shift a VS project with an SQL database connectivity to another new Laptop (above mentioned) ...
I have the project opened in VS without bieng connected to the database..
I have a backup file of the database (which needs to be restored to a new created database on SQL Developer)
The problem:
I am unable to create a server connection in SQL Developer which will allow me to create a new database followed by the recovery from backup file.
I am getting the following error message when I try to create a connection:
Status: Faliure - IO error: The network adapter could not establish a connection
Please help me in setting up a server connection and adding a new sql database

The error message seemed unfamiliar to me and since I had never heard of SQL Developer before, I went to Google. Google might be pulling my legs, but it appears that SQL Developer is related to Oracle. This forum is devoted to SQL Server, so you are in the
wrong place.
Try finding a forum for SQL Developer.

Hi,
Here's a simple application i write to test JSTL.
Using JSTL is easier.
Create a directory named tests in your webapps tomcat directoty.
In this, create a web-inf dir and inside a lib dir.
Copy JSTL.JAR ans STANDARD.JAR in tests/web-inf/lib/ which are lib for JSTL (found on apache foundation web site, jakarta implementation).
Copy you jdbc driver in jakarta-tomcat/common/lib dir.
Here is a file to input some data from an HTML form:
Create saisie.jsp and record.jsp in you tests apps dir.

How TO use configurable Database connection with ADF BC

I have developed a simple JSF/ ADF BC web application that connects to a database and read/display data from the db tables. I have successfully deployed the application to Tomcat 5.5.17. However, now i need to change the database the application is connecting to. My question is How can I change the Database connection without having to change the application modules or rebuild the war file ??? In other words, is there a specific file (xml) where the database connection can be changed?

If you set up the application with a data source (I am not sure if this is possible using another app server, I use OC4J), then you would just change it there. However if you created a database connection in the JDEV and pointed your data model to that, then you will have to change and rebuild.
You might be able to edit the xml file that contains the setttings, I am not sure my CM guys dont allow this, all of our changes have to go through our code repository.

Database connectivity with MS Acess using WSAD5.1

I am using WSAD5.1 as IDE and development tool. I am trying to connect to MS Access database using following lines of code
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //.newInstance();

I tried creating system DSN and changing url as "jdbc:odbc:Test" where Test is DSN.
I have rt.jar file in my class path.
When I run this program from command prompt I am getting connectivity with proper results.
The problem is when it is run with WSAD inweb project I am getting an error
"java.sql.SQLException: No suitable driver".
Am I required to change any environmental settings?

try this Code

Create database connection with Mysql

Hi, all:
inside JDeveloper, i try to create a database connection for Mysql (third party
JDBC driver). I input all needed parameters into
JDeveloper database connection dialog, and test connection, the error message
says 'Unable to find driver org.gjt.mm.mysql.Driver". The jar file contains driver
is listed in system classpath, and Mysql and MM-Mysql JDBC driver are tested with
other applications and there is no problem.
So, what i should do to create such a connection ??
Any help will be appreciated. thank you in advance.
kevin.

The connectio URL could look like this:
(leave the User-, Password-, and Role-fields, in the tab before, empty)
Java Class Name: org.gjt.mm.mysql.Driver
URL: jdbc:mysql://localhost:3306/test?ultradevhack=true&?user=myuser&?password=mypassword

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
