I use firefox version > 3.5 (3.5.,3.6.,4.*) and I try to specify archive
and codebase
property correctly but it doesn't work. My main class for applet is situated in the archive
and some necessary classes that are loaded during runtime are situated in the codebase
. If I specify only the archive
then the applet is loaded but the classes from codebase
are missing. If I specify the archive
and the codebase
then the applet can't be loaded. It looks like applet try to load main class from codebase
folder and doesn't look into the archive
file.
<html>
<body>
<applet width=600 height=300 code="MyClass.class"
type="application/x-java-applet;jpi-version=6"
archive="http://myurl.com/archive/myjar.jar"
codebase="http://myurl.com/classes">
no applet
</applet>
</body>
</html>
Main class is situated in http://myurl.com/archive/myjar.jar and runtime classes are situated in http://myurl.com/classes.
Attribute codebase
specifies the base URL of the applet - the directory that contains the applet's code. It is used while searching jar files in archive
attribute, in such a way that all jars in archive
attribute are searched relative to codebase
.
So. When you use archive="http://myurl.com/archive/myjar.jar"
and codebase="http://myurl.com/classes"
together it means: find "http://myurl.com/archive/myjar.jar" in "http://myurl.com/classes" folder.
I.e. the full search path is "http://myurl.com/classes/http://myurl.com/archive/myjar.jar". And of course it can't be found!
Also, classes, whose jar-files aren't specified in the archive
attribute, can't be found without codebase
attribute. I.e. if there is no codebase
then there is no way to find your classes in "http://myurl.com/classes" folder.
You can find more details in the Deploying With the Applet Tag tutorial.
I suggest the following solution:
myjar.jar
in the http://myurl.com/classes
folder;<html>
<body>
<applet width=600 height=300 code="MyClass"
type="application/x-java-applet;jpi-version=6"
archive="myjar.jar"
codebase="http://myurl.com/classes">
no applet
</applet>
