[13:49]<lvp>lyken,
[13:49]<fdcgg>?
[13:49]<lvp>it gives : java.lang.ClassNotFoundException: org.postgresql.Driver
[13:50]<lvp>my driver is at /usr/share/java
[13:51]<fdcgg>what happens if you specific the driver at runtime
[13:51]<fdcgg>java -cp post...jar
[13:56]<lvp>that's the command to "query" the driver only ?
[13:56]<fdcgg>nah
[13:56]<fdcgg>thats to load the driver when you java YourProgram
[13:57]<lvp>ok, i've done this : java -Djdbc.drivers=org.postgresql.Driver test

[14:01]<fdcgg>same
[14:01]<fdcgg>thats why i dont understand heh

[14:04]<lvp>if there are more that one jar drivers how does java know wich one to use ?
[14:04]<lvp>i have more than one jar drivers in /usr/share/java
[14:05]<lvp>if we not specify the drivers at runtime that is
[14:06]<fdcgg>yer
[14:06]<fdcgg>id assume it was
[14:06]<fdcgg>java -cp postgresql-8.1-407.jdbc3.jar YourJavaClass
