Installtion, Configuring Internet Information Server (IIS) with Apache Tomcat

Internet Information Server (IIS) can not execute Servlets and Java Server Pages (JSP). Using Apache Tomcat redirector plugin (isapi_redirect.dll) will let IIS send Servlets and JSP requests to Apache Tomcat.

This blog explains installation of Tomcat and how to setup IIS to interface with Apache Tomcat 6.0.26.

Install Apache Tomcat 6.0.26
1)Download Apache Tomcat 6.0.26 'zip' or '32-bit/64-bit Windows Service Installer' file and 'unzip' or 'install' it. Download link

2)Submit Request and Get Server Response without doing page refresh.
3)Do the Asynchronous call to the server and get response from it.

This blog is going to explain
1)Send a XML request from Ajax to ASP.NET using C#.
2)Receive a XML Response from ASP.NET using C#to Ajax.

Ajax (Asynchronous JavaScript and XML) - Part 1

Ajax is to update the web page, using data fetched from the server/internet, without reloading the whole page in the browser.  

CAPTCHA Image Code - JAVA, JSP, AJAX

CAPTCHA - Completely Automated Public Turing test to tell Computers and Humans Apart
A CAPTCHA is used to ensure that the response is not generated by a computer, means response from human. It is used to distinguish between human and bots.

Force SSL/https using code - PHP, JAVA, .NET, C#.NET

Below the codes will explain to detect if URL is secured ssl with php, .net or java in https. If not, then code will automatically change to the secured page from http to https.

Executing SQL Server Stored Procedure from PHP

Difference between PHP on Windows and PHP on Linux is:

On windows, the MS SQL Server support module is running as a DLL file. In order to enable the extension, must uncomment the line from the php.ini file : extension=php_mssql.dll

On Linux, the MS SQL Server support module is compiled into libphp5.so, there is no need to load it from extensions.

C# Questions

struct vs Class

• structs are value types that can contain data and functions
• structs are value types and do not require heap allocation.
• structs directly store their data in the struct, classes store a reference to a dynamically allocated object.
• structs are useful for small data structures
• structs can affect performance
• Constructors are invoked with the new operator, but that does not allocate memory on the heap
• A struct constructor simply returns the struct value itself (typically in a temporary location on the stack), and this value is then copied as necessary
• With classes, multiple variables may have a reference to the same object
• It is possible for operations on one variable to affect the object referenced by the other variable.
• With structs, the variables each have their own copy of the data, and it is not possible for operations on one to affect the other.
• structs do not support user-specified inheritance, and they implicitly inherit from type object
