Hi all,
when I try to deploy a web application that runs well on tomcat 7 (it
contains several external library requirements which needs to be
integrated) on WSO2 AS it fails to deploy with the following exception. I
have also used the web-app-classloading.xml to set the environment to
Tomcat.
The following external jars were put into /repository/components/lib :
codenvy-ssl-socket-factory.jar
jul-to-slf4j.jar
logback-classic.jar
logback-core.jar
slf4j-api.jar
to my understanding the error comes due to mismatch in sl4j versions used
in carbon and the web ap being deployed, If so how can I deploy this in
carbon?
Further when my web apps are put in, the default web app jaxrs_basic which
is shipped with WSO2AS also fails to deploy
Can someone point out the reason for this ?
