Number of jazz repository connections via jazz API 4.0


Berthold Kröger (7841623) | asked Mar 17 '15, 9:51 a.m.
Hello, we develop an application that maintains users in many jazz instances. With plain java jazz API 4.0 we face the problem, that the API does not allow for more than 5 connections with jazz instances. When we try to connect to the 6th instance, we get these messages:

Mar 17, 2015 2:39:24 PM org.apache.commons.httpclient.HttpConnection releaseConnection
WARNING: HttpConnectionManager is null.  Connection cannot be released.

Berthold
