Re: [enhydra] Enhydra and JOnAS / EJOSA Problem

["Sinisa Milosevic" <sinisa@xxxxxxxxxxxxx>]

Hi,

Maybe problem is different versions of log4j in Enhydra (we use 1.2.5) and
in Jonas (default implementation for monolog logging in Jonas).
See:

[java] Caused by: java.lang.NoSuchMethodError:
> org.apache.log4j.spi.LoggingEvent.getLevel()Lorg/apache/log4j/Level;

Enhydra uses its own Logger with two possible implementations (log4j and
Standard - old way). You can configure which implementation will be used in
application conf file.

I hope it helps,
Sinisa Milosevic
