Get Connection Error

Question

Dear Friends,
I asked questions about my problem according to get connection with JDBC Driver (you can see my questions with username pourty in the
question list) and JDev Team guided me that I can use the following statements to get connection but unfortunately when I tested the follwing statement I got the same exception (java.sql.SQLException: No suitable driver)
DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver ());
Connection conn = DriverManager.getConnection("jdbc racle:kprb:");
Could anyone please help me that what should I do?
any suggestion would be appreciated.
Thanking in advance

Answer 1

I am getting the same problem, and if I do a search on 'no suitable driver' in this forum there are about 8 different questions each saying that when they run as an application they can connect to Oracle fine, but when they try to when it is running as an Applet, EJB or other similar methods then it doesn't work.
I have done a full installation, and I have tried using the sample jdbcApplet.java that comes with the default install of JDeveloper but this also doesn't connect because of unsuitable driver.
"jdbc:oracle:thin:****/****@*****:1721:******";
The rest of that code is identical.
Thanks very much in advance for you assistance,
Spencer

Amirali, Here is some answers from the
FAQ which will help.
Please see the second item (Q123) for more
details - if things are not working, then
I believe you have an incomplete installation.
Q37: DriverManager.getConnection gives the Error: "No suitable driver"
Make sure that the driver is registered and that you use a connection URL consistent with your JDBC driver. See Using Oracle's JDBC Drivers for the correct values.
Q123: Problem
Some people have run the OUI to install 8i, then written some simple Java code and tried to run it, only to be surprised that their Java code didnt work.
Basically, this is because they have not completed their install.
To be very explicit, running OUI to install Oracle 8i is sufficient IF and ONLY IF you are not using any client side Java and are only interested in a
server Oracle installation. However, if you want to run Java on the client side, there are extra steps to be completed - these steps are listed in the 8i doc.
Some common pitfalls and their solutions are also summarized below.
Solution
Testing your installation - do "Hello World"
We provide a set of samples in $ORACLE_HOME/javavm/demo/demo.tar (or demo.zip for WinNT). These samples have been extensively tested and
do compile and run fine for a "typical" install of Oracle 8i. Please treat these samples just like a seasoned C/C++ programmer would treat a "Hello
World" program - a vital test of the installation. Dont go any further until you at least get these three samples to run.
$ORACLE_HOME/javavm/demo/examples/jsp/helloworld
$ORACLE_HOME/javavm/demo/examples/corba/basic/helloworld
$ORACLE_HOME/javavm/demo/examples/ejb/basic/helloworld
If you cant get these 3 samples to compile and run cleanly in your environment, then you know there is something wrong with your environment.
Similarly, if these work fine, but your code still doesnt run, then you at least know that the installation is ok and that the samples work, so the problem
has to be with your build environment or your code. Note: It is important that you be able to run these examples using the supplied Makefiles (or batch
files on NT) when verifying your installation.
Once these samples have been shown to work in your installation, you can then use the development environment of your choice, or even to manually
building from the command line if you so choose. Please verify that the simple straightforward samples do work, before trying to do anything
more complex.
The following method (below) is copied from:
<OracleHome>\ORA81\javavm\demo\examples\jsp\basic_kprb\Employee.java
public static String getEmpName (int enum) throws SQLException
String name = null;
Connection conn = null;
Statement stmt = null;
try
// load the kprb driver
DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver ());
conn = DriverManager.getConnection ("jdbc :oracle:kprb:");
// create a statement
stmt = conn.createStatement();
// find the name of the employee with the given employee number
ResultSet rset = stmt.executeQuery(
"SELECT ENAME FROM EMPLOYEE WHERE ENUM = " + enum);
// retrieve and print the results
while (rset.next())
name = rset.getString (1);
finally
// don't forget to close the statement
stmt.close();
// return the name of the employee who has the given employee number
return name;
