WebLogic 8.1 SP4 fails to start on FC4 with Java (GNU libgcj)

Question

Hi,
When I use the Java JVM which comes with FC4, my WebLogic server (8.1 SP4) will not boot.
NB It boots with the BEA jdk (also a 1.4.2 version)
I choose the FC4 Java JVM, because then the MySQL's driver mysql-connector-java-3.0.16-ga-bin.jar will work. (Checked
with a simple java program). But the WebLogic server runs off the rails.
Here is the output of ./startWebLogic.sh :
CLASSPATH=/usr/lib/jvm/java//lib/tools.jar:/opt/bea/weblogic81/server/lib/weblogic_sp.jar:/opt/bea/weblogic81/server/lib/weblogic.jar:/opt/bea/weblogic81/server/lib/mysql-connector-java-3.0.16-ga-bin.jar:/usr/lib/jvm/java//jre/lib/rt.jar:/opt/bea/weblogic81/server/lib/webservices.jar:

The WebLogic Server did not start up properly.

Answer 1

The Exceptions before originate from a small java program.
I tested the working of the mysql driver with a small java program as I got these Exceptions when testing a Connection Pool in WebLogic.
The problems with WebLogic and databases started when I used the pointBaseConsole.sh script.
SQL State: 08004
SQL-Server rejected eshtablishment of SQL-connection. Pointbase Server may not be running at localhost at port 9092. NB Of course I have started the Poinbase server. It says it was listening at port 9092
I get these Exceptions both wtih opening an existing (demo) database as with creating a new one.
Here is the small java program: It is compiled/run with java (1.4.x) from FC4 and with java 1.5 from SUN. Both versions worked successfully.
import java.sql.*;
public class MySQLTest {
public static void main (String[] args) throws SQLException {
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
Connection conn = DriverManager.getConnection(
"jdbc:mysql://my.site.com/botenlijst",
"myUser", "myPassword");
// The query we will execute
final String query = "SELECT * FROM fotos";
// Create a statement
Statement stmt = conn.createStatement ();
// Execute the query
ResultSet rset = stmt.executeQuery (query);
// Dump the result
String s = " --- ";
while (rset.next ()) {
System.out.println ( rset.getString(1) + s + rset.getString(2) );
conn.close();
}
