I tried to compile a servlet like this:

javac myFirstServlet.java

It does not work, it get the following message:

package javax.servlet does not exist

How can I compile a servlet?

Urs,
javax.servlet is part of Java EE not Java SE. Your server (Tomcat, JBoss, etc) comes with a file called j2ee.jar or servlet.jar. Add this to your classpath when compiling.

I know, that javax.servlet is not part of Java SE. I use Apache Tomcat. I found servlet.jar. So far so good.

How shall I continue?

This is the path:

C:\Programme\Apache Software Foundation\Tomcat 6.0\lib\servlet.jar

javac -classpath C:\Programme\Apache Software Foundation\Tomcat 6.0\lib\servlet.jar myFirstServlet.java

Is it something like that? Or do I have to copy servlet.jar in folder lib of the jdk?

Till now it does not work.

Do not copy the jar file anywhere. You can include it in the classpath in-place. Otherwise you risk jars getting out of sync with each other.

Now it worked, I could compile it. I did it like that:

set classpath=C:\Programme\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar

Then:

javac myFirstServlet.java

But I do not want to enter the first line always. Is it possible to set it in the operating system, in Microsoft Windows XP you can set in System the variables.

Use the CLASSPATH variable.

You can set the CLASSPATH as either a user variable or system variable. As the name says, if it is set as a user variable, it is available for the particular user. If it is set as a system variable, the classpath is available to all.

Thank you, now it works fine. I set the environment variable CLASSPATH.
 
It is sorta covered in the JavaRanch Style Guide.
