In my example, I used JNDI for lookup and RMI for communications, but I do not know what interface you are planning on using. When you say the logs indicate it's registered, it implies (to me) that your object is actually getting created - verify that, but your likely culprit is that you have something not quite working when you go to access the object.Darrel Sharpehttps://www.blogger.com/profile/14983275921276526024noreply@blogger.comtag:blogger.com,1999:blog-3327656862902751997.post-82251675055830067482012-11-06T01:47:38.531-08:002012-11-06T01:47:38.531-08:00Hi,

Maybe this is because, for example, I want a single instance timer to fire off a message that would trigger occasional batch processing - I don't want every server to fire off such a message, in this case. I could achieve the exactly once functionality by doing partial cluster deployment, but I wouldn't get the failover functionality that the Cluster Wide Singleton gives me.<br /><br />Darrel Sharpehttps://www.blogger.com/profile/14983275921276526024noreply@blogger.comtag:blogger.com,1999:blog-3327656862902751997.post-70458671744761359672012-10-02T11:55:21.952-07:002012-10-02T11:55:21.952-07:00You should only see it bound on the server where i...You should only see it bound on the server where it is active.Darrel Sharpehttps://www.blogger.com/profile/14983275921276526024noreply@blogger.comtag:blogger.com,1999:blog-3327656862902751997.post-59916596682806015992012-09-05T09:17:52.230-07:002012-09-05T09:17:52.230-07:00Hi Darrel.
