Configuring Https in Axis2

If a client is connecting a https server, he has to trust the certificate of the server, and the developer has to provide the trusted certificates to the client. http://ws.apache.org/axis2/1_5/http-transport.html is the closest reference I found, which basically says look at httpclient configurations, and also thread http://www.opensubscriber.com/message/axis-dev@ws.apache.org/8077606.html discusses how to do this.

Basically Axis2 depends on commons http client security and it uses JSSE security. So setting following properties will do. However, httpclient also provides more deeper control.

System.setProperty("javax.net.ssl.trustStore",
     "/data/playground/ebay-sept30/wso2esb-2.1.0/resources/security/client-truststore.jks");
System.setProperty("javax.net.ssl.trustStorePassword","wso2carbon");

Simplify data extraction using Linux text utilities

Simplify data extraction using Linux text utilities is a very nice article that teach how to do text magic with the Unix shell, and these commands become handy with pipe (|) operator.

Abstract: Management architectures are well discussed in the literature, but their application in real life settings has not been as well covered. Automatic management of a system involves many more complexities than closing the control-loop by reacting to sensor data and executing corrective actions. In this paper, we discuss those complexities and propose solutions to those problems on top of Hasthi management framework, where Hasthi is a robust, scalable, and distributed management framework that enables users to manage a system by enforcing management logic authored by users themselves. Furthermore, we present in detail a real life case study, which uses Hasthi to manage a large, SOA based, E-Science Cyberinfrastructure.
