Onsen UI – face to cordova

Standard

Onsen UI As an experiment, I was trying to look for options available to improve default look & feel of the cordova application. After going through various blogs and forums, I realized that there are various options available to choose from. After visiting each of these options, I thought to gave a try for onsen.

Onsen is primarily based on AngularJS and extends HTML by adding its own tag definitions. For the behavior management, framework utilizes AngularJS. The website has plenty examples to try out, various controls that come with Onsen. Primarily Onsen has very rich set of components and it has been backed with good documentation.

QTP – Identify renderers within DataGrid

Standard

Recently, I came across a problem in QTP automation – failing to identify controls within DataGrid. The problem was occurring with one of our legacy application, using Flex SDK 3.5 (yes, its truly legacy). The issue was almost driving nuts, as DataGrid in quite a few other modules were working proplery with QTP, while one of the screen was failing in object detection.

GSON as JAX-RS json provider in CXF

Standard

While there are many frameworks for parsing JSON structured data, I was looking for a framework which will provide a generic object. I was expecting a returned object to be more like a property holder (no Hashmaps, please). I came across GSON and found it is the perfect candidate for what I am looking for.
But my problem was not addressed completely, I was looking for embedding GSON inside CXF as JAX-RS provider. The default implementation which comes with CXF, was returning a concrete object which was impossible for me to build and make available to the provider. Hence, I needed a way to configure GSON as JAX-RS provider and capitalize the features which I was more interested in.
This led the way to build my own JAX-RS provider using GSON. Fortunately, it is much easier with CXF to create JAX-RS provider and plug it in the framework.
Step 1
Create a class “GSONJAXRSProvider” and implement

javax.ws.rs.ext.MessageBodyReader
javax.ws.rs.ext.MessageBodyWriter

Step 2
Override the method to parse incoming data.

public Object readFrom(Class object, Type arg1, Annotation[] annotations, MediaType mediaType, MultivaluedMap httpHeaders, InputStream inputStream) throws IOException, WebApplicationException

I have used following code to deserialize data

InputStreamReader streamReader = new InputStreamReader(inputStream);
JsonElement jsonObject = parser.parse(streamReader);
return (Object)jsonObject;

Step 3
Override the method to serialize outgoing data.

public void writeTo(Object object, Class arg1, Type arg2, Annotation[] annotations, MediaType mediaType, MultivaluedMap httpHeaders, OutputStream responseStream) throws IOException, WebApplicationException

And here goes code for serializing JSONObject to string.

PrintWriter printWriter = new PrintWriter(responseStream);
JsonObject json = (JsonObject)object;
printWriter.write(json.toString());
printWriter.flush();

Step 4
Configure the newly created class as JAX-RS provider in CXF. Refer following configuration snippet.






That’s all!

Windows 8.1 upgrade

Standard

I was bit excited waiting for new upgrade of Windows 8 – Version 8.1. I have Samsung Ativ Smart PC Pro – XE700T1C model, bought almost 2 years back. The strong feature of this model is that it can be detached from the keyboard and has i5 processor with 128gb SSD. I found its quite handy while reading books, surfing, listening music and yes sometimes even coding Java-Eclipse. Overall this is the best purchase, I have ever made. There is only one thing that bugs me – is the keyboard docking. Anyways, lets move to what I experienced after upgrading to Windows 8.1.
Few months back one of senior manager has indicated in the post that he is bit obsessed with the Windows 8.1 upgrade. But I still thought of upgrading my laptop cum tablet without even thinking what was waiting for me. It was just a week old story that I started seeing windows 8.1 upgrade was waiting for me in the store. I thought lets just upgrade it and see what new features are available.

Eclipse product export with features

Standard

Sometime back, I started doing a formal release of one of the Eclipse RCP product, I was working on. While doing the release, I came across lot of problems. My product has very simple structure and it consists of

  1. Plug-in (Core functionality for RCP)
  2. A Feature (Contains above plug-in)
  3. Another feature (To list all the eclipse dependencies)
  4. Product definition plug-in (Contains branding and workbench details)
  5. Product definition (Created inside above plug-in)

That seems pretty simple huh!!! But while exporting above structure, I came across lot of things that one may find useful. Let evaluate everything from the beginning.

Eclipse Context Help – Complete

Standard

You may be confused as why I am posting about the feature which is covered by so many posts/articles/documentation. Though there are many sites which does this job, I found one or the other configuration aspect is missing from either of the site. I personally followed many articles and could never able to get the context help worked. I had to visit many sites and understand what are all combined configuration aspects are required to get it done. This provoked a thought to put all those things together. Here we go

I am lost

Standard

Long time, no see. Nothing came from my side, for a long time. Hmm, thats bit scary and even made me think, as what I am doing? I am bit lost these days, lost in the plethora of information, reading lot of books on topics ranging from Javasript, Java, .Net, performance, coding best practices etc. (list will not end and the backlog is still increasing). The sad part is I am not able to use my knowledge at my workplace and mostly it is fact that I must accept I am working in a country where management is more of value than hard-core technical skills (hmm god knows, I can tell you from my experience).

Nodejs and custom modules on windows

Standard

It has been a long time, I was planning to hit on Node.js, but I got stuck with other topics and somehow it slipped my mind. Few days back, I thought to give it a try and check what Node.js offers. I like the idea of using JavaScript to write code for Node.js (After all thats my first programming language and the most fav. language :P ).
The first baby step with “Hello World” and writing your own web server, made me comfortable and I realised its so much of fun to write code for nodejs as you have to just learn the APIs and start modularizing them. As soon as I started making the progress, I found an example making use of Node.js’s custom module “connect”.

Books that help to write better code

Standard

I have been reading lot of books on various frameworks and technologies from my college days. I am always fascinated by new technologies and frameworks that help to ease developer’s life by writing less and manageable code. While all these years, I was spending too much time on reading syntaxes and APIs exposed by various languages and frameworks, from last 2 months, things have taken different turn. I put too much emphasis on using design patterns, but I was introduced to quite a few good books by my seniors and I was really surprised, the way these books have changed my thoughtprocess. No, I dont mean stop using design patterns or blah blah… but before start using all those geeky words like scalability, design patterns and other stuffs, you need to first learn to write clean code. Yes! here are some of the best books, I have been reading.

Firefox 22 Installer – usability

Standard

It was just like a regular day and I was going through few sites, suddenly I felt to checkout if there is any new version of Firefox has came up (I check bi-weekly). And yeah, there was new version available. As usual, I tried to upgrade using the Help > About firefox menu and it showed that there is new version is availble. While usually it updates the firefox without doing much and just by opening About box, but this time it failed. So to get the latest version, I tried to download it manually. Hmm… and then I was bit shocked by the installer.
