Opencms in Java

Question

I have installed the OPENCMS in the Tomcat and I have configured it in eclipse. At first I was doing well but now it gives me error. I have the Tomcat version 7 and java 7. This is the error that I get:

Answer 1

Had this exact issue today with a different app and it ended up being that oracle.net.aso.C00 was in multiple jars.

Found with following snippet of bash:

in the WEB-INF/lib folder run

for jar in $(ls *jar); do unzip -l $jar ; done | grep -P '(^Archive|oracle.net.aso.C00)'

which resulted in:

Archive:  com.springsource.oracle.jdbc-10.2.0.2.jar
      804  02-04-2009 13:18   oracle/net/aso/C00.class
...
Archive:  ojdbc14-10.2.0.4.0.jar
       683  02-02-2008 11:39   oracle/net/aso/C00.class

needed to remove one of the jars.
