I wrote following 2 servlet classes and saved them in directory C:\Documents and Settings\VEENA\JavaServlets ,where JavaServlets is package name.
class 1

class2

Class2 compiles fine ,but class1 is giving compiler error saying
HelloServlet3.java:17: cannot resolve symbol
symbol : variable ServletUtilities
location: class JavaServlets.HelloServlet3
out.println(ServletUtilities.headWithTitle(title)+

I have included C:\Documents and Settings\VEENA\JavaServlets and root directory ;. into the classpath.But still geting the compiler error.What might be the problem?
Thanks
Veena

U have to find out where the compiled classes are placed after the compilation of ServletUtilities class and u have to set that folder to the classpath, not the folder that the source files are in...
If u use the standard location specified by the specification like under /WEB-INF/classes/JavaServlets, it will be easier to debug and maintain your web app... Otherwise, u'll have to find out everything manually...
Hope this helps....

ko ko,
class files are placed in the same directory as source files.i.e C:\Documents and Settings\VEENA\JavaServlets
I checked it.Then logically it should not throw compiler error right?
Please reply
Thanks

No it will surely throw the compilation error, if ur HelloServlet3 cannot find the class that it has to use in its code... Why don't u try to place the class under the /WEB-INF/classes/JavaServlets and try to compile the HelloServlet3 again?
I think it is because ur HelloServlet3 class is trying to find that ServletUtilities class under that folder...

I got it
Was setting classpath wrongly.I changed classpath from C:\Documents and Settings\VEENA\JavaServlets to C:\Documents and Settings\VEENA
Now it is working

Veena, I'm curious to know what web container you are using... Seems like u are developing the servlets on ur own and they are not under the specified folder as in the specification?
or you just want to test whether they are compiled or not... If I am not wrong, u have to deploy them in the appropriate folders to be able to run them properly as a part of ur web app...
Just curious on ur implemention....

Try the following...
In directory:
C:\Documents and Settings\VEENA>
and use javac compiles:
C:\Documents and Settings\VEENA>javac \JavaServlets\HelloServlet3.java

Yep, it is the root directory which needs to be in the classpath. Javac will automatically traverse the package structure from there.

Ko Ko,
I didn't have problem with deploying servlets,I know how to run servlets,I had problems with simple java packages.BTW I am using Tomcat5.016 servlet container.And this is the directory I am putting class files into to make servlets with packages examples I mentioned earlier run.
C:\tomcat5.0\webapps\ROOT\WEB-INF\classes\JavaServlets
Thanks

Veena, it's good that u know how to deploy... I'm just afraid that u developed the servlets outside and don't know how to deploy it in the real application...
And also if u have placed your classes in the folder that u specified above, u don't need to set the classpath for that... Coz it's automatically done by the web container...
Just my 2 cents...
 
It is sorta covered in the JavaRanch Style Guide.
