Solution:Error adding derby jars to project

I recently trying to add the derby plugin into the eclipse. When I try to add derby nature (PS: right-click on the java project -> "Apache Derby" -> "Add Apache Derby nature"  ),I get the pop up says :

Error adding Derby jars to the project: org.eclipse.ui.internal.WorkbenchWindow cannot be cast to org.eclipse.jface.window.ApplicationWindow

error pop up

Does this picture look familiar? Error adding Derby jars to the project

What I was Using is when facing this problem :
  • jdk1.7.0_03
  • Eclipse IDE for Java EE Developers (Win32) version Juno (build from 2012/06/14) 
  • derby-core-plugin 10.8.2 and -ui-plugin 1.1.3 (as there is no eclipse plugin for the latest version 10.9.1.0) 

I also google about this problem before but i can't find any solution. After I try many time ,I finally found a way to solve it! A bad method,but take a look!

Solution:
The solution is download another version of Eclipse IDE for Java EE Developers like Europa!
You can download the europa version at the eclipse website.
http://www.eclipse.org/downloads/packages/release/europa/winter
Then follow the instruction to install derby into the eclipse.It should be work!At least it work on my computer.
If you can solve the problem using the juno version , you may share the method at the comment below! Thank you for reading.

Reading and Writing Operation of SRAM

Image
The diagram below is illustrate Static Random Access Memory (SRAM)Cell for the explanation. SRAM cell is make up of 2 inverters are cross-connected to form a latch .The latch is connected to 2 bit line by transistor T1 and T2 . T1 and T2 can switch opened or closed under control of word line.When word line is ground level, the transistors are turned off and the latch retrains its state. During the Read Operation ,Word line is activated to close switches T1 and T2 . If the cell is in state 1; the signal on b line is high and the signal on b’ line is low.The opposite is true if the cell is in state 0.Thus, b and b’ are always complements of each other’s. The sense /write circuit at the end of the two bit line monitors their state and sets the corresponding output accordingly. While in Write Operation ,the Sense/Write circuit drives bit lines b and b’, instead of sensing their state.It places the appropriate value on bit line b and its complement on b’ and activate the word ...

Reading & Writing Operation of DRAM

Image
In Dynamic Random Access Memory CELL , transistor acts as a switch to Close (allowing current to flow) when voltage applied in address line or Open (no current flow) when no voltage applied in address line.Address Line also known as word line .Which use to signal the transistor to close or open. During the Write operation ,a voltage is applied on the bit line and a signal applied to the address line to close the transistor.Then the voltage applied on the bit line will transfer to capacitor and store in the capacitor However the capacitor has tendency to discharge and has to refresh to maintain the bit. While in Reading Operation ,the instruction find the bit store using the address line to read the data or bit. When the address line is selected ,the transistor turns on and the charge stored on the capacitor is fled out onto a bit line and to sense amplifier. Sense amplifiers compare the capacitor voltage to reference value to determine the logic 1 or logic 0.The read out from ...

Method to Convert from Stream to Json C#

Recently I was using the C# HttpClient to make REST request but I found that is was quite troublesome so I have changed to using HttpWebRequest instead. So want the HttpWebRequest result is return it was in Stream form. I not able to convert it into Json. this is the method i convert the stream to JSON. HttpWebResponse response = ( HttpWebResponse ) requirejs . GetResponse (); Stream stream = response . GetResponseStream (); StreamReader sr = new StreamReader ( stream ); var serializer = new System . Web . Script . Serialization . JavaScriptSerializer (); var jsonObject = serializer . DeserializeObject ( sr . ReadToEnd ()); As you can see that jsonObject is an object. Now you can parse it into the Json(JsonObject); If you have any question can leave a comment below.
