Hi Julien,
So this is a JDBC program indicating the JDBC driver (virtjdbc4_1.jar) is
causing the issue, did you compile this from source also ?
Running against the latest develop/7 build you sample program does run without
error for me:
[virtuoso@masala vos]# javac -cp
"/2d2/git/virt-develop7/libsrc/JDBCDriverType4/virtjdbc4_1.jar:." Test.java
[virtuoso@masala vos]# java -cp
"/2d2/git/virt-develop7/libsrc/JDBCDriverType4/virtjdbc4_1.jar:." Test
[virtuoso@masala vos]#
[virtuoso@masala vos]# more Test.java
import java.sql.*;
import java.sql.DriverManager;
import java.sql.Connection;
public class Test {
public static void main(String[] args) {
try {
Connection conn =
DriverManager.getConnection("jdbc:virtuoso://localhost:1234/", "dba", "dba");
} catch (SQLException ex) {
ex.printStackTrace();
}
}
}
[root@masala vos]#
[root@masala vos]# isql 1234
