Subject: [Pljava-dev] java.lang.SecurityException
Date: Wed, 20 Apr 2005 13:09:08 +0200
Message-ID: <2276557F1C7668499FF59EC75B84624FC7A6B6@salsa.cefriel.it> (raw)

I made as you suggested. But the result now is: no suitable driver.
The CLASSPATH does not exist and in the postgresql.conf 
variable pljava.classpath has only pljava.jar.

this is my change in the source

public class Test {

	public static String test() {
		String ret = "nu cazz!!!!!!!!";
		try {
			/*
			Class.forName("org.postgresql.Driver");
			String url =
"jdbc:postgresql://etechsviluppo.cefriel.it/context";
			Properties props = new Properties();
			props.setProperty("user", "context");
			props.setProperty("password", "context");
			Connection conn =
DriverManager.getConnection(url, props);
			*/
			Connection conn =
DriverManager.getConnection("jdbc.default.connection");
			Statement s = conn.createStatement();
			...

thank you,
Luca

1) Don't use the PostgreSQL client jdbc driver inside of PL/Java since 
that will a) create a network connection to another PostgreSQL session 
and b) have a transaction-scope that is decoupled from the 
transaction-scope of the executing function. In order to obtain a 
connection, please do:

Connection conn =
DriverManager.getConnection("jdbc.default.connection");

2) Never have anything but the pljava.jar in the postgresql.conf 
variable pljava.classpath or in the CLASSPATH env seen by the postmaster

process . Jar files *must* be loaded using sqlj.install_jar
