Hi,
When I'm trying to start the embedded tomcat server I'm getting following
exception. Could someone tell me why am I getting that? Did I missed
anything in configuration?
I'm using JDK 1.8 and tomcat 8.0.20

I have extended the *StandardService *class and override the *startInternal
*method as follows
protected void startInternal() throws LifecycleException {
if (log.isDebugEnabled()) {
log.debug("starting extended standard service : " + this);
}
setState(LifecycleState.STARTING);
// Start our defined Container first
if (container != null) {
synchronized (container) {
container.start();
}
}
synchronized (executors) {
for (Executor executor : executors) {
executor.start();
}
}
mapperListener.start();
}
I debug the code and found out that container.start(); throws the
Exception. My *server.xml* file is as follows
