java - How do I get started with JFreeChart? -


i've never used third party library before. should after downloaded jfreechart-1.0.14.tar.gz?

i don't know if i'm doing these things right:
1. put jcommon-1.0.17.jar , jfreechart-1.0.14.jar @ same directory source code.
2. import needed class in source code (e.g. import org.jfree.util.rotation;)

many articles tell how in ides. instead of ides, i'm writing codes vim , compile myself. so, assume didn't thing wrong, how should compile source code javac , run code java?

edit:

here's file layout:
./src
| - test.java
./lib
| - jcommon-1.0.17.jar
| - jfreechart-1.0.14.jar

i compile by
javac -cp "lib/*" -d classes/ src/test.java
run by
java -cp classes:lib/jcommon-1.0.17.jar:jfreechart-1.0.14.jar test

however, error occurs:
exception in thread "main" java.lang.noclassdeffounderror: org/jfree/data/general/piedataset

how can resolve problem?

exception in thread "main" java.lang.noclassdeffounderror: org/jfree/data/general/piedataset   @ java.lang.class.getdeclaredmethods0(native method)   @ java.lang.class.privategetdeclaredmethods(unknown source)   @ java.lang.class.getmethod0(unknown source)   @ java.lang.class.getmethod(unknown source)   @ sun.launcher.launcherhelper.getmainmethod(unknown source)   @ sun.launcher.launcherhelper.checkandloadmain(unknown source)   caused by: java.lang.classnotfoundexception: org.jfree.data.general.piedataset   @ java.net.urlclassloader$1.run(unknown source)   @ java.net.urlclassloader$1.run(unknown source)   @ java.security.accesscontroller.doprivileged(native method)   @ java.net.urlclassloader.findclass(unknown source)   @ java.lang.classloader.loadclass(unknown source)   @ sun.misc.launcher$appclassloader.loadclass(unknown source)   @ java.lang.classloader.loadclass(unknown source)   ... 6 more

the libraries shouldn't @ same place source code. if don't want use build tool gradle yet, handle library dependencies, suggest using following layout:

project     src         .java files here, organized in folder tree matching package tree     classes         compiled .class files here     lib         .jar files here

to compile, go in project directory , execute following command:

javac -cp lib/jfreechart-1.0.14.jar:lib/jcommon-1.0.17.jar -d classes src/com/foo/bar/myclass.java src/com/foo/bar/myotherclass.java

to run app, execute following command:

java -cp classes:lib/jfreechart-1.0.14.jar:lib/jcommon-1.0.17.jar com.foo.bar.myclass
