explorer.jar cannot work without objectdb.jar, and the error indicates that objectdb.jar is not available in the classpath.

There is no objectdb.jar , only objectdb-ee.jar i saw.

I renamed objectdb-ee.jar to objectdb.jar

This time i got this error:

KadirBASOL:bin apple$ bash explorer.sh

What exactly do you mean by there is no objectdb.jar?

Download the last version of ObjectDB and run the Explorer in the bin directory, which should contain objectdb.jar.
