Error compiling java subclass from command prompt

[littleone]

Good Afternoon,

I have been trying for about an hour to compile two java subclass for the Command Prompt. All of the classes are in the same directory.

The classes are as follows:

Book.java - the superclass

ChildrenBook.java - a subclass of Book

TechnicalBook.java - a subclass of Book.

All of the files are saved under this folder:

C:\tomcat\webapps\begjsp-ch07\WEB-INF\classes\com\wrox\library

This is the command I am running at the command prompt:

javac com\wrox\library\Book.java
javac com\wrox\library\TechnicalBook.java
javac com\wrox\library\ChildrenBook.java

The Book.java class compiles, but when I run the above commands, I get this error message:

cannot find symbol
symbol: class Book

I have attached my CLASSPATH, the error message, and the all of the java classes.

Please directly me on exactly what is causing this problem. I have a feeling it has to do with my CLASSPATH not being setup properly. I am using Tomcat 6 with jdk 1.6.0_21


Thanks in advance for all of your help.

First, when you run the command in your command promt you are in C:\tomcat\webapps\begjsp-ch07\WEB-INF\classes, right?

Set the classpath to the current directory ('.')! (or you can use the -classpath/-cp option in javac)

try

javac -cp . com\wrox\library\TechnicalBook.java
javac -cp . com\wrox\library\ChildrenBook.java

(-cp = -classpath)

javac com\wrox\library\Book.java is not necessary

or you can use the wildcard (you do not have to set the classpath AFAIR)

javac com\wrox\library\*

I am sure that it because of classpath.

You better go through

PATH and CLASSPATH (The Java™ Tutorials > Essential Classes > The Platform Environment)

Thank for the reply. I want to make sure that I am understanding you right.

First you want me the change the set the CLASSPATH to include the ".". (Please see jpg attachement).

Secondly, yes I did enter the correct path. (Please see my a screen shot of my command from yesterday).

I will take your suggestions you provide and post my results.

Thank for the fast and concise suggestions you provided. I really appreciated.

[littleone]

Sure enough that was the case.

All I needed to do was to add the "." to the beginning of the CLASSPATH and rerun the javac command along with the path and the two files compiled.

Thanks for the help. I will be back pretty soon bugging you all for more help because I am having problems getting my servlets to work.

1. run the command FROM command promt going to --> C:\tomcat\webapps\begjsp-ch07\WEB-INF\classes location.

2. Set the classpath to the current directory ('.').

3.
execute the following

javac -cp . com\wrox\library\TechnicalBook.java
javac -cp . com\wrox\library\ChildrenBook.java

(-cp = -classpath)

4. javac com\wrox\library\Book.java is not required
