[Pljava-dev] cannot set the classpath to a specific jar to get anexternal connection

How are you connecting? Is it something like this:

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

String connectionUrl = "jdbc:postgresql://" + server +
":" + port + "/" + database;

conn = DriverManager.getConnection(connectionUrl,
userName, password);

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.ja
va: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?
