Libraries and jar files.

I have written a library. It is in a com/telmap/mapapplet directory.
A. How do I put all the class files in a jar file so that I can use the library from within the jar file?
B. Where do I place the jar file relatively to the code that wants to use it?

A. Making your .jar file:
jar cvf myjar.jar com/telmap/mapapplet/*.class

B. You can put your .jar file where you want. Only must refer it in a CLASSPATH. For example, if "myjar.jar" is located in C:\com\jars:

CLASSPATH=%CLASSPATH%;c:\com\jars\myjar.jar

Is it´s an applet, you can refer it through tag ARCHIVE in the .html. With CLASSPATH runs too.

Another posibility with main programs will be:

java -jar myjar.jar

Bye... :)

Mine is an applet -- What exactly do I type in the HTML tag?

ori_b

Your HTML tag should look like this :
<APPLET CODE = classname.class ARCHIVE = myjar.jar>
</APPLET>

But I already have the whole applet in a jar file, so my HTML tag already looks like:
<APPLET CODE = MyApplet.class ARCHIVE = MyJarredApplet.jar>
</APPLET>

ori_b

where is MyApplet.class located in the jar ?
if it is in com/telmap/mapapplet/ then
you tag should change to:

<APPLET CODE = com.telmap.mapapplet.MyApplet.class ARCHIVE = MyJarredApplet.jar>
</APPLET>

No, I want to have 2 jar files, one with the applet, and another one with the com.telmap.mapapplet library. I want to run the applet, which would use the library.
