Question

I tried to import my ant script. And it successful. But when i compile it. I got this error:

run-selected-file-in-src:
java.io.FileNotFoundException: ..\sounds\voice.wav (The system cannot find the path specified)
        at java.io.FileInputStream.open(Native Method)

D:\Windows\My Document\Latihan\Java\allsrc\ch04src\nbproject\ide-file-targets.xml:7: Java returned: 1
BUILD FAILED (total time: 0 seconds)

This is my folder structure

root
+-build(all *.class store here)
+-images
+-nbproject(netbeans create it)
+-sounds(voice.wav where i want to load)
+-src(all *.java - When i compile. All *.class will store to "build" folder)
+-build.xml

My question is why the class file(SimpleSoundPlayer.class) didn’t find “..\sounds\voice.wav”. But when i tried it from command-line “java SimpleSoundPlayer” it fine.

Why this happen?

Answer 1

I FIGURE IT OUT!!!
Special Thx to “JB Nizet”. Because him i know why it didn’t find the wav file. So i just search how to change the default location(this case in root) netbeans to compile(I want netbeans to compile from “build” folder).

The key is in nbproject/ide-file-target.xml

root
+-build(all *.class store here)
+-images
+-nbproject(netbeans create it)
+-sounds(voice.wav where i want to load)
+-src(all *.java - When i compile. All *.class will store to "build" folder)
+-build.xml

<?xml version="1.0" encoding="UTF-8"?>
<project basedir="../build" name="chap04 - Sound Effects and Music-IDE">
    <!-- TODO: edit the following target according to your needs -->
    <!-- (more info: http://www.netbeans.org/kb/41/freeform-config.html#runsingle) -->
    <target name="run-selected-file-in-src">
        <fail unless="run.class">Must set property 'run.class'</fail>
        <java classname="${run.class}" failonerror="true" fork="true">
            <classpath>
                <pathelement path="build"/>
                <pathelement location="."/>
            </classpath>
        </java>
    </target>

So i just change on <project basedir=".." to <project basediir="../build" where i want netbeans to compile. With this change netbeans will compile that file in “build” folder. AND… WOWWW… That file run correctly 😀
