Hello,

Forgive me if this is a stupid question, but I am having trouble compiling the First.java on the Developer Guide documentation. I am getting the error "cannot resolve symbol" on all the imports. I have followed everything on the guide and was successfull in doing everything up to this point. What did I miss?

Post the exact command line you entered and the error displayed.

Hello Dave,

This is what I am getting:

C:\jfreechart-1.0.0-rc1>javac First.java
First.java:1: package org.jfree.chart does not exist
import org.jfree.chart.ChartFactory;

.
.
.

First.java:16: cannot resolve symbol
symbol : class DefaultPieDataset
location: class First
DefaultPieDataset dataset = new DefaultPieDataset();

These are the paths:

PATH=c:\j2sdk1.4.2_07\bin\;c:\jfreechart-1.0.0-rc1\;c:\apache-ant1.6.5\bin\

Thank you for your quick response.

Regards,

jmartin

This is not a problem of jfreechart. Try to get a good book to find out more about java. In this case you forgot to tell the java compiler where to find the jfreechart library. The easiest way is to copy jfreechart-1.0.0-rc1.jar into the same directory as your First.java file and compile it like this:
javac -classpath jfreechart-1.0.0-rc1.jar First.java

Notice that for execution you have to specify the path of your resulting class file and the jfreechart library. Example:
java -classpath .;jfreechart-1.0.0-rc1.jar First
