To protect sensitive data encryption is the standard way. Its highly recommended if you are dealing with sensitive data, the application database connection also need to be encrypted. In this article we will go through how to establish a secure JDBC connection to Oracle database.  1) We need to turn on encryption in oracle server. We can do that by starting Oracle Net Manger. There we have to select Oracle Advance Security and in Encryption tab there is option to turn on Encryption for server.There is ... (more)

I found ADF af:query is very useful. It provide out of box search and reporting capability. Typically we define some search criteria in View Object, and we use that criteria as af:query component. All the labels we see in the page can be internationalized by using resource bundle in normal way. For some labels we can use the below properties of af:query                               ·         headerText                              ·         resetButtonText                              ·         saveButt...

New Post Some common exception while working on ADF and triaging

posted by pallab_rathpallab_rath 287 days, 15 hours, 56 minutes ago

Usually this issue appears with Tree Table, when we modify the model associated with the tree. The UI state (disclosure and section information) is captured corresponding UI component object. When the model is updated those state become invalid. And when the tree try to restore the old state with new set of data then there could be a situation where this NoRowAvailableException can occur. To avoid this better to clear the selection when model is updated. And then immediately partial refresh the tree ... (more)

It’s a common topic In  java interviews. And these two methods are always common to any class you write in Java. So let’s know them in and out. boolean equals(Object  obj) and int hashCode() are two methods implemented in Object class with several other methods.  In Java every class implicitly inherit Object class so every class has these methods.  Equals method check the reference is holding same object or not.MyClass obj1 = new MyClass();MyClass obj2 = 0bj1;Then obj1.equals(obj2) returns true.MyClass o...

Wednesday, July 25, 2012 7:47:39 AM GMT
To find anything in internet the best way is googling. Any one who use internet the first thing they learn is googling. When I say googling it include all web search like Bing,Yahoo etc. I do googling to read news, to watch video, to check weather, movie sports etc.Since information is scattered in different website, and they are too many to remember. So people use search engine to locate their content. Few years back everything was working in this pattern, we used to search stuffs on web and browse our ... (more)

In my starting days of coding I had a notion if you don't understand the code means its a tough program, some hi-fi advanced code. And if the code compile with out error and execute properly means its perfect in all aspect. My first programming language was C. There was a lab exam where we need to code 5 given program. I had completed well ahead of time, all the five were compiling and running properly. The teacher was checking each student's program and evaluating. You have to get minimum three progra... (more)

With each passing days we realize " man proposes and god disposes" , well we plan some thing if there is an deviation we called it exception. Exceptions are annoying and we just hate it. More or less each exception holds lots of vital information of reality,  to go forward we need to decode these exception. I have not much idea how to decode the exceptions that life throw, but in Java we can certainly plan it very well. Java got a one of the advanced way to handle exception.

My Experiments With Java: All about imports in Java

In any Java source file first line after package declarations are import statements.  These statements enable us to use different classes from outside package. Compiler always looks at the import statements to find class definition. Instead of import statements we can write fully qualified name. For ex: java.io. File file = new java.io.File(filepath); This is a perfectly valid statement. Only problem is it looks littlie complicated to read.  Good codes are not only run well but also easy to read. So...

In any football match you will find the coach jumping, screaming telling something to the players. Its not only in football even in Cricket and other sports the coach will try to give some more information to the players on field.Though there was a detail game plan which involve coach, captain and all players much before the match. They know what to do everything is planned, still the coach has to say "one more thing" while the game is in progress. Same case with us developer, we used to think and  des... (more)

We will always find middle man in between producer and consumer of anything. Sometimes more than one layer of middle man. Both producer and end user hate those middle man. They just rip profit by somehow involving in transaction. But no one will deny it require lots of thinking to establish a model which doesn't need middle man. Let’s understand what kind of value these middle men bring. Like real world every software or services is integration of various modules. Each module is responsible to carry out... (more)

ExtJs is an popular java script framework. To develop rich and interactive user interface, extjs is used. It is a basically library of java script component which are ready to use in webpage. ExtJs components work very well with JSON data. If in server side we decide to Spring as framework. Its very easy to integrate ExtJs with Spring. In Spring MVC we can easily configure FTL (free marker technology) for specific to ExtJs Component. FTL is something which is responsible to convert java objects to desire... (more)

When and Why We should use Ajax When first time I learned the term Ajax. I was trying to understand what kind value it will add. Before that I will tell one of my funny experience I was driving with my friend near to Bangalore. It was 1:30 PM. We were searching some small hotel for lunch. We found a one near to the highway. We went there it was a normal road side Indian hotel. There were few people were eating. We ordered a veg thalli for each. The waiter served us a proper south Indian thalli. It h... (more)

In a typical web application or any GUI based application, MVC pattern is widely followed. MVC says there is a clear separation between presentation layer, processing layer and the persistent layer. I always imagine any private or MNC bank where there are front office people, Nice, beautiful soft spoken who are the user interface. And in back office some ugly, tuff and smart mangers who run the business.   Similarly we design our java application and I assume this holds good for mostly in Object oriente... (more)
