Hi all,
Is anyone else using:
IPT 2.1.1 on CentOS 6.5 Java 1.6.0_30 Tomcat 6
Connecting to:
SQL Server 2008 R2 Windows 2008 Server
We had been operating just fine with 2.0.4 since last fall. We recently updated to IPT 2.1.1 about two weeks ago. Now we are unable to connect to our SQL Server instance. We’re getting:
java.lang.UnsupportedClassVersionError: net/sourceforge/jtds/jdbc/Driver : Unsupported major.minor version 51.0 (unable to load class net.sourceforge.jtds.jdbc.Driver)
(We also upgraded the SQL Server database/server recently, but I think that was working fine for at least two weeks before we upgraded our IPT.)
Does anyone know how to fix (or help us further diagnose) our “unsupported major.minor version 51.0” problem?
Thanks,
-Stan
Hi Stan
On my phone, so just quickly...
This is saying the SQL server library needs java 7. I'm not sure how that gets put into the IPT off the top of my head, but it will require the jar file in web-inf/lib to be replaced with an older java 6 version.
Alternatively... Upgrade Java. Java 7 has been out for a long time now, so probably worth planning for anyway, if feasible.
Hope this helps,
