Hello!
Thank you for reply!
How developers pass parameters to their web applications? There are several
ways of doing it. One of them is: put parameters to web.xml as Environment
entry. It is very convinient.
But it appears that I can change this value in admin application. And this
change is not visible in JNDI :-(
I have to restart tomcat to see new parameters ... or change them in admin
and reload contex.
Maybe it is of no importance for others, but I really care :-)
I made some researches and I think, that
org.apache.catalina.core.NamingContextListener class should be corrected:
it was:
public void lifecycleEvent(LifecycleEvent event) {
...
// Binding the naming context to the class loader
if (container instanceof Context) {
// Setting the context in read only mode
ContextAccessController.setReadOnly(getName());
try {
ContextBindings.bindClassLoader
(container, container,
((Container)
container).getLoader().getClassLoader());
} catch (NamingException e) {
log(sm.getString("naming.bindFailed", e));
}
}
...
}
I think, it should be:
public void lifecycleEvent(LifecycleEvent event) {
...
// Binding the naming context to the class loader
if (container instanceof Context) {
namingResources.addPropertyChangeListener(this);
// Setting the context in read only mode
ContextAccessController.setReadOnly(getName());
try {
ContextBindings.bindClassLoader
(container, container,
((Container)
container).getLoader().getClassLoader());
} catch (NamingException e) {
log(sm.getString("naming.bindFailed", e));
}
}
...
}
With this modification changes in Admin application are visible in JNDI.
Could you please tell you opinion - is this modification ok?
Thank you,
Igor

Hi,
I think there's been an open bugzilla issue for this for months. It's
such a marginal use-case that (as evidenced by the fact no one's done it
for months) no one seems to care, given the two workarounds in your
post. So if you really care, maybe you could submit a patch?
