No, sorry!
 
3. How can I put class files in a different directory?
you should use CODEBASE parameter inside the applet tags of the Html file
e.g.: <APPLET CODEBASE="classes" CODE="TreeApplet.class" WIDTH=280 HEIGHT=380>
 
4. TreeApplet class not found!
this could be due to your ftp program that converts filenames to lowercase
Note:Java classes are case sensitive
 
5. Netscape: TreeApplet class not found!
you need to add the CODEBASE parameter inside the applet tags of the Html file in that way:
e.g.: <APPLET CODEBASE="." CODE="TreeApplet.class" WIDTH=280 HEIGHT=380>

at least one java class file is corrupted, class files may have been uploaded in ascii instead of binary

9.How to install TreeApplet using frames?
Following is an example of settings with a left frame (TreeApplet) and a right frame. You will need three Html files (index.html, toc.html, and hello.html):

index.html:
. This is the main file that will be called by web navigators.
. This file contains information about the 2 frame's names and the initial documents to be visualized
. eg:

<HTML>

<FRAMESET COLS="250,*">

<FRAME NAME="leftframe" SRC="toc.html">
<FRAME NAME="rightframe" SRC="hello.html">

</FRAMESET>

</HTML>



hello.html:
. this is the frame that will be displayed on the right side of the browser's document
.eg:

<HTML>

Hello Happy Taxpayers

</HTML>


toc.html:
. this frame will be displayed on the left side of the browser's document.
. this frame contains the TreeApplet command, and will display the tree interface.
. eg:

<HTML>



<APPLET CODE="TreeApplet.class" WIDTH="220" HEIGHT="380">

<PARAM NAME="Tree_ScriptFile" VALUE="script.txt">

</APPLET>


</HTML>
