Thread: Driver fails to connect

Driver fails to connect

Hi.

Using J2sdk1.4.0, Postgresql7.2, and a patch, 1.4b3.

Try: DriverManager.getConnection("jdbc:postgresql:Paul","Paul","")

Get: java.lang.NoSuchFieldError: current_row
      at org.postgresql.Driver.connect(source file unknown, pc 0x82063333)

The preceding is preceded by (18 iterations of) Warning: Major/Minor version number mismatch.

I'm sure this is some sort of configuration glitch.  I have postgresql.jar and pgjdbc2.jar in the same directory which is in my classpath.  What am I missing/what did I not do/what did I not do that I should have?

Thanks,
Paul

Paul,
 
Chances are the class loader is going to load pgjdbc2.jar first and take it as the Driver. there must be more code than this though?
 
Can you send us a snippet of code that reproduces the error?

Paul,
 
Using the standard jar which will run under jdk1.4 I got the following response
 
In TestJdbc constructor
DRIVER: org.postgresql.Driver
Connecting to Database URL = jdbc:postgresql:test
