How to use Vlookup

Example formulae for vlookup is

=VLOOKUP(D4,'[OtherExcelFile.xlsx]OtherExcelFileSheetName'!$H$112:$I$120,2,TRUE)

here

D2 is column I am finding
H112 to H120 is records to search in
I112 to I120 is record rows which I have to bring.
2 is column I am referring to i.e I column here.


You can use match which is more easy than Vlookup for this task.

Getting started with Java Servlet

What is Java Servlet
Java Servlets are programs that run on a Web or Application server and act as a middle layer between a requests coming from a Web browser

Architecture

Request comes from browser to HTTP server and then to servlet.

Servlet process this request and interact with database and send response via same channel.

Servlets can be created using the javax.servlet and javax.servlet.http packages.

Methods of Servlet javax.servlet.Servlet Interface

1. Init()

2. Destroy()

3. Service()

4. getServletConfig()

5. getServletInfo()

Servlet API 

Servlet API cotains 4 package

1. javax.servlet

2. javax.servlet.http

3. javax.servlet.annotation

4. javax.servlet.descriptor

javax.servlet:- Contains classes and interfaces that define the contract between a servlet and a servlet container.
javax.servlet.http:- Contains classes and interfaces that define the contract between an HTTP servlet and a servlet container.
javax.servlet.annotation:- Contains annotations to annotate servlets, filters, and listeners. It also specifies metadata for annotated components.
javax.servlet.descriptor:- Contains types that provide programmatic access to a web application’s configuration information.

5.       Worklight Application Center: This is a cross-platform mobile application store that fulfils specific needs for mobile application development teams.

     One can view app.xsd for checking definition of app.xml
     Location of app.xsd is .\Anywhere\lib\codegen\artifac-processor-7.5.2.jar\app.xsd

How to delete a folder you are not able to delete to due to long path.

ExampleC:\Very long path.... to be deleted you can use the command

Go to path and enter

subst x: .
