Java Bridge not running...

DavidHourani — Wed, 10 Jun 2015 16:45:43 GMT

Hello Splunkers,

I recently updated to 6.2.3 and db connect stopped working... anyone has had the same problem ?

I am running DBconnect v1.

I have the following message that is being repeated in /var/log/splunk/jbridge.log

2015-06-11 10:29:29,075 ERROR Command output: None

Hi @DavidHourani

Can you include what version you're using? DB Connect 1 or DB Connect 2?

$SPLUNK_HOME/var/log/splunk/jbridge.log
What does the log say ?

Your java version is incompatible.

Supported versions:
DB Connect 1.1.x requires Java 1.6 or 1.7 only.
DB Connect 1.2 requires Java 8 only.
DB Connect 2.0 requires Java 8 only.

You are using the wrong Java version:

2015-06-11 10:29:31,685 ERROR Java process returned error code 1! Error: Exception in thread "main" java.lang.UnsupportedClassVersionError: com/splunk/bridge/JavaBridgeServer : Unsupported major.minor version 52.0

The error means that the Java Bridge is Java 8, and your JVM is not.

If your're using DBConnect v1.2, it looks like you need Java 8 (although the app page says not):

Thanks for your help. Eventually i found the fix on the troubleshooting guide:

Fix: If you suspend and restart a VM on which the Java Bridge Server is running, make sure to restart Splunk. Also, remove any stale state.xml files from $SPLUNK_HOME/var/lib/splunk/persistentstorage/dbx.

Simply had to delete the state.xml file and restart ^^
