10 years ago Adding information from my responses to the email thread:
This 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(); } } }

OpenLink Virtuoso Server Version 07.10.3211-pthreads for Linux as of Jul 12 2014 Started on: 2014-07-13 01:14 GMT+2
my JDBC Driver version which is the same as yours as would be expected being from the repo:
[virtuoso@masala vos]# java -jar /2d2/git/virt-develop7/libsrc/JDBCDriverType4/virtjdbc4_1.jar OpenLink Virtuoso(TM) Driver for JDBC(TM) Version 4.1 [Build 3.70]
My Java version is:
[virtuoso@masala vos]# java -version java version "1.7.0_05-icedtea" OpenJDK Runtime Environment (rhel-2.2.1.el6_3-x86_64) OpenJDK 64-Bit Server VM (build 23.0-b21, mixed mode)
The the problem would appear to be in the JDBC Client (although we are both using the same jar), The JDBC/Java runtime (as we are running slightly different versions) or the Virtuoso develop/7 server build, as although we are both compiling against the same develop/7 branch. might your build options to be different to mine ?
Can you confirm the Linux Distro and version being used as well as a copy of the Makefile see we can see what options are set for the compile ?

Hello,
I put here my actual issue about the Virtuoso JDBC drivers currently discussed on the mailing list with @HughWilliams . So to resume I use the last version of Virtuoso contained in develop/7 branch. I compiled it with these lines in the configure :
And at the end I also recompiled the
virtjena2.jarfile with this new classpath :To get this version :
The JDBC drivers are those provided by default in the repository :
And :
The code that I try to execute is as simple as this :
And an error occurs each time I try to use these drivers as you can see it there with
virtjdbc4_1.jar:And with
virtjdbc4.jar:My Virtuoso as I said is the one from the develop/7 branch :
And my Java version is :
Now here what is written inside the
virtuoso.logfile after each try to execute this little Java script :Trace_on()and the optionCallstackOnExceptionsetted at 2 in thevirtuoso.inifile don't give any more information than the line above.Hope all these informations will help.
Best.
Julien.
