Yes, I've installed the jar before ( I did not mention) and then I was able to 
set the classpath using the jar alias. However, keeping the jar separated or 
merging them into a single jar does not solve the problem and the error still 
is:


ERROR:  java.sql.SQLException: No suitable driver found for 
jdbc:postgresql://localhost/myDb

and in the logs I've got the stacktrace:

java.sql.SQLException: No suitable driver found for 
jdbc:postgresql://localhost/myDB
        at java.sql.DriverManager.getConnection(DriverManager.java:602)
        at java.sql.DriverManager.getConnection(DriverManager.java:185)
        at itpug.pljava.RowGenerator.getResultSet(RowGenerator.java:40)
        at 
org.postgresql.pljava.internal.ResultSetPicker.<init>(ResultSetPicker.java:25)

Summarizing this is what I've done:
1) sqlj.replace_jar to my new jar containing the Java client
2) sqlj.install_jar for the postgresql driver jar
3) set the classpath so that now I've got:
select sqlj.get_classpath('public');
 get_classpath 
---------------
 driver:myJar
(1 row)

with driver the jar for the jdbc driver, and myjar the jar of my client.

Any suggestion?
