Have the same problem

Do we need the :classes:. after the servlet jar?
It doesn't seem to compile after if I use it.

[Mohd Fuzail]

javac -classpath C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib\servlet-api.jar -d<location of your class file> <src-file>

If you are on windows then please put claspath in double quotes

javac -classpath "C:\Program Files\Apache Software Foundation\Tomcat 5.0\common\lib\servlet-api.jar" -d<location of your class file> <src-file>

[Ken Teoh]

Tried it without the quotes and it works. However, can some one explain what is the command ":classes:." after the servlet-api.jar is used for? I took it out and it works

Hi Friends,
Now I am able to compile as I followed all your instructions.
But now the problem is its not taking servlet-api.jar.

[satya mahapatra]

On Compilation its showing error like this
Cant resolve symbol class Httpservlet,HttpservletRequest,ServletException......


FYI................

C:\MyProjects\beerV1>javac -classpath :\ProgramFiles\ApacheSoftwareFoundation\Tomcat5.0\common\lib\servlet-api.jar:classes: -d classes src\com\example\web\Beer
Select.java

I got the same problem initially
check the path of your servlet-api.jar
if you're desperate place the jar file in the same directory as your java source file and it should compile

[Cai DongShan]

You should use ; instead of : in Windows system.

Please try the command below.

javac -classpath C:\Program Files\Apache Software Foundation\Tomcat 5.5\common\lib\servlet-api.jar;classes;. -d classes src\com\example\web\BeerSelect.java

Hi friends i tried all your sugestions. But its still showing same error.
1. Cai DongShan I changed : to ; But it isnt working.

2.Ken Teoh I put the jar file in inside my source file and also inside lib of jdk. Then also not working.

But when I am giving set classpath in command prompt it is showing the servlet-api.jar.

What can be the problems???
I am not able to find out.Anyone faced the similar problems please help.

[Cai DongShan]

satya,

There is not space in the command you post. You create a batch file to include the following lines and try to run the batch file again.

C:
cd \MyProjects\beerV1>
rem copy my command here

[satya mahapatra]

Hi Friends,
At last I got it.What I did is first I uninstall the previous tomcat and again install it and gave the classpath. Now it is working.

To check classpath is working or not we can type command
javap javax.servlet.Servlet

Thanks for all your inputs.
