I am using Eclipse Indigo running on Ubuntu and I am trying to set up a Tomcat server following the last part of this guide:

http://wiki.openbravo.com/wiki/How_to_setup_Eclipse_IDE

My problem is that when I try to boot the Tomcat server I get this error (Server Tomcat v6.0 Server at localhost failed to start.):

enter image description here

My console looks like this:

Caused by: java.lang.UnsupportedClassVersionError: org/openbravo/base/ConnectionProviderContextListener : Unsupported major.minor version 52.0 (no puedo cargar clase org.openbravo.base.ConnectionProviderContextListener)

What can I do? I tryed adding tomcat-juli.jar to my server classpath, which is the main solution I have found but it didn't work.

Thanks in advance.

EDIT:

Thanks to the answer Tomcat starts but does not make the resource available. There are compilation errors in the Openbravo projects as well.

Update your JDK version. The classes were probably compiled in a JDK version higher to yours.

Edit: Probably it is JDK/JRE 8.

  • In my .bashrc I have export JAVA_HOME=/home/user/Documentos/jdk1.8.0_05 Could eclipse be running another version of Java? How can I check it? – yafrack May 07 '14 at 07:25
  • Change the JDK version for your project. You may refer here: http://stackoverflow.com/questions/12588537/how-to-change-jdk-version-for-an-eclipse-project – Dhrubajyoti Gogoi May 07 '14 at 08:42
  • When I do so I only get options up to 1.7, not a trace of 1.8. – yafrack May 09 '14 at 07:26

  • Glad you got it resolved by yourself. I thought you already had JDK 8 installed. But I fail to understand why a opensource project would compile with JDK 8 in its early days. It probably is a bad move, unless they are using some Java 8 specific features. – Dhrubajyoti Gogoi May 09 '14 at 08:22
  • Do you know why now, even though the server does start I get a 404 Openbravo resource not found? – yafrack May 14 '14 at 06:51
  • I guess the application is not deployed. Check the server tab, in your screenshot it is the first one. There you should have a tree like view of the applications deployed (not very sure though). Also check the logs for the string 'openbravo', if it is deployed or an attempt was made to deploy it, there should be some mention of it in the logs. – Dhrubajyoti Gogoi May 14 '14 at 10:24
  • I added the deploy tree you mentioned as a picture. The folder logs at tomcat folder is empty at the moment. – yafrack May 15 '14 at 07:12
