Subject: Re: Running Embedded Tomcat from Java Web Start
Hi Andrew,
The problem is not Tomcat, its WebStart, I hate that thing... know I'm
going to get flamed ;)
WebStart also seems to crash with RPC applications... and I think that as
soon as an application has classloaders in it, Web Start is touch and
go...
Also I imagine you know you have to get certs and all that stuff....
Anyway, I got so the dispondant with web start I made my own app called
IGNITION.
You can get it at http://coolese.100free.com/
Briefly... you have your embedded app... you build it... then look under
your "build" folder and you will see the class structure for your app...
(ie you dont have to unpack a jar).
Ha ha... correction, confusing it with my application server... just drop
the app into the folder...
point URL at it... it will run... sorry!
IGNITION is a web-app... you drop it into Tomcat and its installed... then
you drop the CLASS structure into the START folder... thats it.
If you call that URL... it will install on the clients machine... no certs
required.
Have Fun...

Subject: Running Embedded Tomcat from Java Web Start
Hi All,
I'm trying to launch Embedded Tomcat from Java Web Start (JNLP), but
without any luck so far. I've searched high and low and found several
folks who have tried this approach but no one has seemed to succeed.
Just to clarify, I'm not trying to run Java Web Start from Embedded
Tomcat, but actually the reverse: start Embedded Tomcat on the client's
machine, via Java Web Start.
Tomcat starts but I get the following exception:
----------> Parent Classloader:
[EMAIL PROTECTED]
org.apache.jasper.servlet.JspServlet
java.lang.ClassNotFoundException:

Apparently a classloader issue with JNLP, but I don't know how to set the
classloader on Tomcat.
I also tried launching Embedded Tomcat via a URLClassLoader. With the
URLClassLoader I get: java.security.AccessControlException: access denied
(java.util.PropertyPermission catalina.home write). It seems that the
URLClassLoader is not running with the same privileges as the JNLP
classloader.
I'm using the following code to start tomcat.
System.setProperty("catalina.home", getPath());
embedded = new Embedded();
Engine engine = embedded.createEngine();
engine.setDefaultHost("localhost");
host = embedded.createHost("localhost", getPath() + "/webapps");
engine.addChild(host);
Context context = embedded.createContext("", getPath() +
"/webapps/ROOT");
host.addChild(context);
embedded.addEngine(engine);
Connector connector =
embedded.createConnector((java.net.InetAddress) null, 11080, false);
embedded.addConnector(connector);
embedded.start();
Any suggestions will be appreciated.
Andrew
