Hello,
I have caught a problem of using embedded Jetty and slf4j, may be you
can help me.
Jetty tell me this one:
java.lang.LinkageError: loader constraint violation: when resolving
method
"org.slf4j.impl.StaticLoggerBinder.getLoggerFactory()Lorg/slf4j/ILoggerFactory;"
the
class loader (instance of org/eclipse/jetty/webapp/WebAppClassLoader)
of the current class, org/slf4j/LoggerFactory, and the class loader
(instance of sun/misc
/Launcher$AppClassLoader) for resolved class,
org/slf4j/impl/StaticLoggerBinder, have different Class objects for the
type org/slf4j/ILoggerFactory used in the
signature [main o.e.j.u.l.Slf4jLog.warn:111]
I have next jars:
Embedded Jetty classpath:
slf4j-api-1.5.10.jar
logback-classic-0.9.18.jar
War libs:
slf4j-api-1.5.10.jar
But I add
slf4j-api-1.5.10.jar
logback-classic-0.9.18.jar
to WAR libs and delete
logback-classic-0.9.18.jar
from jetty classpath, all work fine.
Best regards,
Aleksey Didik
