Hello everyone,
I am developing some webobjects(wonder) applications and when I want to deploy
them on a linux server, within a tomcat, I get this error (HelloWorld examples
for simplicity) :
Dec 09 12:51:37 HelloWorld[-1] WARN NSLog - Failed to get localhost address

initialized.java.net.UnknownHostException: <my_host>: <my_host>: Name or
service not known

It works fine on a local tomcat (I develop under Ubuntu), but not on my server
(tomcat under RedHat Enterprise). Do you guys have any idea about what is going
on ? Maybe I miss a configuration property, or maybe it is caused by a network
configuration ? Other tomcat apps work (like tomcat manager).
On another subject, because of some work constraints, I try do work under
windows and everything is fine, I can run my Wonder Application inside eclipse
but when I try to launch it on a local tomcat, I get the following exception:
java.lang.IllegalArgumentException:
<com.webobjects.appserver._private.WOComponentDefinition> Class 'Main' exists
but is not a subclass of WOComponent.
I already encountered this error (only on windows) an fixed it with something
I found in the mailing archives in order to specify the right main class:
_NSUtilities.setClassForName(Main.class, Main.class.getSimpleName());
But this time, nothing seems to change.
Thanks for your help.
Regards,
Anthonin LIZÉ
