Re: SQL-Database Clustering and Loadbalancing with Geronimo

Hi Rudi,

I'm not sure if this is exactly what you're looking for, but we have some
documentation on 'WADI Application Distribution Infrastructure':
http://cwiki.apache.org/GMOxDOC21/wadi-clustering-support.html which might
prove to be a good place to start for your solution.  Also, I've seen
references on the list to a third party called "Terracotta" at
http://www.terracotta.org/ which provides some scalable solutions you can
work with AG on.

Re: Remote EJB Connect - Initial Context, host unknown Exception

2008-05-19 Thread ApolloX 

I did some exploring into the source code of openejb 2.1 and stripped away
the offending code:

final String serverURL = "ejbd://127.0.0.1:4201";
final URL url = new URL("http://"+serverURL);
final InetAddress inet = InetAddress.getByName(url.getHost());
 
Now, if I catch the exception it, it throws a similar exception openejb
reported:
 
java.net.UnknownHostException: ejbd: ejbd
at java.net.InetAddress.getAllByName0(InetAddress.java:1145)
at java.net.InetAddress.getAllByName(InetAddress.java:1072)
at java.net.InetAddress.getAllByName(InetAddress.java:1008)
at java.net.InetAddress.getByName(InetAddress.java:958)
 
Its adding http + ejb for connection strings resulting in a url of:
"http://ejbd://127.0.0.1:4201";.  First question, is this an invalid URL? 
The URL class does not throw an error on creating this URL.  The method
url.getHost() returns "ejbd".
 
Next, I took the code snippet and removed the "http://"; and tried this code:

final String serverURL = "ejbd://127.0.0.1:4201";
final URL url = new URL(serverURL);

But I get an exception on the second line of:
java.net.MalformedURLException: unknown protocol: ejbd
at java.net.URL.(URL.java:574)
at java.net.URL.(URL.java:464)
at java.net.URL.(URL.java:413)
 
Any suggestions?
