Project: OpenEJB
Issue Type: Bug

When deploying an EAR (containing web modules) I get the following Exception:
org.apache.openejb.OpenEJBException: Creating application failed:

Debugging shows that the reason is in the constructor of TomcatWebAppBuilder. I
can fix the NullPointer if I patch the constructor as follows:
OLD:
for (LifecycleListener listener : host.findLifecycleListeners()) {
if (listener instanceof HostConfig) {
HostConfig hostConfig = (HostConfig) listener;
deployers.put(host.getName(), hostConfig);
}
}
NEW:
if (listener instanceof HostConfig) {
HostConfig hostConfig = (HostConfig) listener;
if(hostConfig.getConfigBaseName() != null) {
deployers.put(host.getName(), hostConfig);
}
}
In some cases the method getConfigBaseName() returns null (I suppose in the
cases when the context.xml is put in the web module META-INF and not in
conf/Catalina/localhost).
Adding a hostConfig to the deployers map with hostConfig.getConfigBaseName() ==
null results in the reported NPE in
org.apache.catalina.startup.HostConfig.manageApp.
