Quick Start for WebSphere Liberty Profile – Deploying a WAR

Filed under: Uncategorized — Davanum Srinivas @ 12:58 pm

Download the WebSphere Application Server V8.5 Alpha Liberty Profile from:

Create a new web app using maven:

Unzip the server:

dims@dims-desktop:~$ unzip -q Downloads/

Let’s use the default server for deploying our war

dims@dims-desktop:~$ cd was4d/usr/servers/defaultServer/

See which features are enabled

dims@dims-desktop:~/was4d/usr/servers/defaultServer$ cat server.xml
<server description="new server">

<!-- Enable features -->


Add support for servlet and jsp’s

dims@dims-desktop:~/was4d/usr/servers/defaultServer$ vi server.xml
dims@dims-desktop:~/was4d/usr/servers/defaultServer$ cat server.xml
<server description="new server">

<!-- Enable features -->


Create a directory for dropping in our WAR

dims@dims-desktop:~/was4d/usr/servers/defaultServer$ mkdir dropins
dims@dims-desktop:~/was4d/usr/servers/defaultServer$ cd dropins/
dims@dims-desktop:~/was4d/usr/servers/defaultServer/dropins$ cp ~/my-webapp.war .
dims@dims-desktop:~/was4d/usr/servers/defaultServer/dropins$ cd ../../../..

Start the server

dims@dims-desktop:~/was4d$ date
Sat Oct 8 13:50:50 EDT 2011
dims@dims-desktop:~/was4d$ bin/was4d start
Starting defaultServer ...

Let’s see how long it took…just a few seconds.

iPhone and a bit of Rain

Filed under: Uncategorized — Davanum Srinivas @ 5:29 pm

Last week we were at the Animal Kingdom down in florida we ran into a bit of rain. I quickly wore a rain jacket and transferred the iPhone to the more drier pocket of the rain jacket, but the iPhone got a bit wet anyway. The iPhone shut off by itself and i could feel the battery draining. Back at the hotel, after a bit of research, found that thankfully the sensors had not tripped. I popped open the sim card and dried it with a hair dryer for about 5-10 mins and dropped it into a snack bag with rice. Left the iPhone alone for a couple of days with periodic drying with the hair dryer and it’s now working as well as it was. Whew!

What is JSONx?

Filed under: Uncategorized — Davanum Srinivas @ 11:57 am

[SOURCE] Please see Slide #37 in

What is JSONx?

• IBM Internal Standardization of JSON modeled in XML
– xmlns:json=
– Spec was developed by DP with input from the Data Web Service Team (DB2)
– Strict model of RFC 4627 – application/json
– Productized by DP and Data Web Service Team
• Developed to be generically schema validateable (json is validated)
– Not an arbitrary representation of JSON data as XML
– Not at attempt to model any XML as JSON
• Developed to be a non-lossy transformation of JSON types/data
• Useful for everything DataPower
– RESTful json bridge to SOAP
– Threat protection for Ajax clients that use eval(json)
• Data Web Service details:

[My Notes]
• Datapower devices live on the edge of your network
• Customers perform bridging/proxying/aggregation of various data formats and protocols
• It’s in this narrow use case that JSONx is aimed at IMHO

Here’s an exact AJAX DataPower Appliance SOAP scenario:

The official conference, trainings, and expo of The Apache Software Foundation (ASF) returns to Atlanta this November, with dozens of technical, business, and community-focused sessions at the beginner, intermediate, and advanced levels.

Over the past decade, the ASF has gone from strength to strength, developing and shepherding nearly 150 Top-Level Projects and new initiatives in the Apache Incubator and Labs. This year’s ApacheCon celebrates how Apache technologies have sparked creativity, challenged processes, streamlined development, improved collaboration, launched businesses, bolstered economies, and improved lives.

We are proud of our achievements and recognize that the global Apache community –both developers and users– are responsible for the success and popularity of our products.

The ApacheCon Planning Team are soliciting 50-minute technical presentations for the next conference, which will focus on the theme “Servers, the Cloud, and Innovation”.

We are particularly interested in highly-relevant, professionally-directed presentations that demonstrate specific probrlems and real-world solutions. Part of the technical program has already been planned; we welcome proposals based on the following Apache Projects and related technical areas:

– Cassandra/NoSQL
– Content Technologies
– (Java) Enterprise Development
– Felix/OSGi
– Geronimo
– Hadoop + friends/Cloud Computing
– Lucene, Mahout + friends/Search
– Tomcat
– Tuscany
Submissions are open to anyone with relevant expertise: ASF affiliation is not required to present at, attend, or otherwise participate in ApacheCon.

Please keep in mind that whilst we encourage submissions that the highlight the use of specific Apache solutions, we are unable to accept marketing/commercially-oriented presentations.

Other proposals, such as panels, or those longer than 50 minutes in duration have been considered in the past. You are welcome to submit an alternate presentation, however, such sessions are accepted under exceptional circumstances. Please be as descriptive as possible, including names/bios of proposed panelists and any related details.

All accepted speakers (not co-presenters) qualify for general conference admission and a minimum of two nights lodging at the conference hotel. Additional hotel nights and travel assistance are possible, depending on the number of presentations given and type of assistance needed.
