I followed the instruction of NetBeans IDE to create the JAR file.
and the files structure is
-...TestCell4.4(root folder)
|
+--build(folder)
|
+--dist(folder)
|
|--+--javac(folder)
|
|---TestCell4.4.jar
| |
| |--META-INF
| | |
| | |--MANIFEST.MF
| |
| +--BinaryFile.class
| |
| +--Combox.class
| |
| |--TestCell.class
|
|--+nbproject(folder)
|
|--+src(folder)
|
|--+test(folder)
|
|--build.xml
|
|--large_plotdata.bin
|
|--manifest.mf
my html code is
<html>
<title>Test</title>
<head>
</head>
<body >
<applet code = "Combox.class" archive="TestCell4.4.jar" width ="800" height = "800" >
<br>
<br>
</applet>
</html>
Combox.class,TestCell.class,BinaryFile.class,TestCell4.4.jar,larger_plotdata.bin, and test.html these six files are in the same folder.
