Ubuntu and writing Java servlets

to server java web jsp jre jdk class sun j2 j2ee jar war system 6 5 classpath path servlet by chrelad on Aug 22, 2008
Kind of a strange, and I'm sure this wouldn't have happened on any other distribution of Linux, but I spent forever looking through blogs, message boards, and all manner of other places looking for an answer to this question.

The problem was with this little itty bitty smidge of code:
/**
 * hello.java
 */
import javax.servlet.*;

class HelloWorld
{
        public static void main(String[] args)
        {
                System.out.println("Hello World!");
        }
}


Everytime I wanted to compile this, I got something like "Could not find javax.servlet. blah blah" So, eventually, I just pulled an apt-cache search j2 (for j2ee) and saw an entry for libservlet2.4-java. Hmmmmm, what the heck is that I wondered. I installed it and went to the Ubuntu site to look at what files were installed and sure enough:

/usr/share/java/jsp-api-2.0.jar
/usr/share/java/jsp-api.jar
/usr/share/java/servlet-api-2.4.jar
/usr/share/java/servlet-api.jar


Perfect! I added these paths to my CLASSPATH variable in my .bashrc and whamo, I'm in business and flaunting my little HelloWorld.class file all around town.

I hope this helps someone else!

Retrieve MSSQL table information

to sql server tsql mssql table microsoft column information properties sysproperties systables data type types length columns by chrelad on Aug 08, 2007
Retrieve tons of information (length, data type, name, etc.) of columns for a table. Works in (T|MS)SQL (all I've tested it in).

SELECT * FROM information_schema.columns WHERE table_name = 'Customers'
