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 inarchive
attribute, in such a way that all jars inarchive
attribute are searched relative tocodebase
.So. When you use
archive="http://myurl.com/archive/myjar.jar"
andcodebase="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 withoutcodebase
attribute. I.e. if there is nocodebase
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 thehttp://myurl.com/classes
folder;
