Making a single jar file from differnet packages

[admin]

Hello,I am developing an applet which uses the classes in four different packages.Allthe four packages and the appletsubclassare in the same directory.when I open the HTML page withcode="appletsubclass.class" everything works fine.*********Problem with the jar**************After deployment on the webserver to reduce the number of connections betweenthe browser and the webserver (everytime a class is instantiated )I wantedto make a single jar file with all the classes.**********current directory******************************HTML fileAppletsubclass which is the entry class for the browsercompany-division-product---data-(*.class)---graphics(*.class)---server(*.class)********************************************************To make a jar file encompassing all the class files I created a Jar packageas belowto add classes from data directoryjar cfv allclasses.jar company/division/product/data/*.classthen to add classes from graphics directory to the same jar filejar ufv allclasses.jar company/division/product/graphics/*.classthen to add classes from server directory to the same jar filejar ufv allclasses.jar company/division/product/graphics/*.classonce all the classes are added to allclasses.jar fileI test it by extracting it and found every thing ok.Then in the HTML fileI said in the applet tag<applet code="appletsubclass" archive="allclasses.jar" width=600height=600>My curent directory is f:\jartestingwebgraphics\withtwowhen i open this file the browser gives me the following exception in thejava consolecom.ms.security.SecurityExceptionEx[CBKHGR0002.init]: java.io.IOException:bad path: F:\jartestingwebgraphics\withtwo\company\division\product\superappletsubclass.classat com/ms/security/permissions/FileIOPermission.check (FileIOPermission.java)at com/ms/security/PolicyEngine.deepCheck (PolicyEngine.java)at com/ms/security/PolicyEngine.checkPermission (PolicyEngine.java)at com/ms/security/StandardSecurityManager.chk (StandardSecurityManager.java)at com/ms/security/StandardSecurityManager.checkRead (StandardSecurityManager.java)at java/io/File.isDirectory (File.java)at sun/net/www/protocol/file/FileURLConnection.connect (FileURLConnection.java)at sun/net/www/protocol/file/FileURLConnection.getInputStream (FileURLConnection.java)at com/ms/vm/loader/ResourceLoader.getURLData (ResourceLoader.java)at com/ms/vm/loader/ResourceLoader.getCodebaseRelativeData (ResourceLoader.java)at com/ms/vm/loader/ResourceLoader.getClassData (ResourceLoader.java)at com/ms/vm/loader/URLClassLoader.findClass (URLClassLoader.java)at com/ms/vm/loader/URLClassLoader.loadClass (URLClassLoader.java)at java/lang/ClassLoader.loadClassInternal (ClassLoader.java)at CBKHGR0002.init (CBKHGR0002.java)at com/ms/applet/AppletPanel.securedCall0 (AppletPanel.java)at com/ms/applet/AppletPanel.securedCall (AppletPanel.java)at com/ms/applet/AppletPanel.processSentEvent (AppletPanel.java)at com/ms/applet/AppletPanel.processSentEvent (AppletPanel.java)at com/ms/applet/AppletPanel.run (AppletPanel.java)at java/lang/Thread.run (Thread.java)java.lang.ClassNotFoundException: company.division.product.data.superappletsubclass.classat com/ms/vm/loader/URLClassLoader.loadClass (URLClassLoader.java)at java/lang/ClassLoader.loadClassInternal (ClassLoader.java)at CBKHGR0002.init (CBKHGR0002.java)at com/ms/applet/AppletPanel.securedCall0 (AppletPanel.java)at com/ms/applet/AppletPanel.securedCall (AppletPanel.java)at com/ms/applet/AppletPanel.processSentEvent (AppletPanel.java)at com/ms/applet/AppletPanel.processSentEvent (AppletPanel.java)at com/ms/applet/AppletPanel.run (AppletPanel.java)at java/lang/Thread.run (Thread.java)What do I need to do to rectify this error and create a jar filecontaining all the class files from different packages?Why I am I getting a security exception using the jar filewhen everything works fine when the browser downloads each classitself?
