Обсуждение: jdbc

I'm having trouble getting the postgresql jdbc driver to work.  Here's my error:
java.sql.SQLException: No suitable driver       at java.sql.DriverManager.getConnection(DriverManager.java, Compiled
Code)      at java.sql.DriverManager.getConnection(DriverManager.java, Compiled Code)       at
DBBean.<init>(DBBean.java,Compiled Code)       at DBBean.main(DBBean.java, Compiled Code)
 

I'm running Linux with the 1.2.2 jdk.
I'm running pgsql 7.0.2.

CLASSPATH=/usr/lib/pgsql/jdbc7.0-1.2.jar:.

Any help would be appreciated.

Did you use 'Class.forName("org.postgresql.Driver")', to preload the
driver prior to calling getConnection?

Maybe you had the same naming issue I found (see below).

Subject: JDBC documentation error

Hi Peter,


I'm just getting started with postgres and JDBC. I wanted to mention 
a documentation error that might cause considerable pain for other 
newbies like me :)

You have:

In the first method, your code implicitly loads the driver using the 
Class.forName() method. For Postgres, you would use:

Class.forName("postgresql.Driver");


In using this, my application kept crashing (of course it should have 
given me an error message, but for some reason it just crashed). I 
finally got things working by changing it to

Class.forName("org.postgresql.Driver");

Thanks for all your work,

John DeSoi, Ph.D.
