Hi group.

I am looking at Snippet157 (embedding word into applet) and wondering how it
would work in real life (i.e. in a regular browser and not in appletviewer).

I imagine, that I'll probably need to include swt.jar in the applet tag, but
am wondering if I would also need to include the .dll files and how would
that work exactly?

Thanx for any help,
- Kalman

P.S. The snippet looks very convincing, but if you can't take it outside of
eclipse appletviewer - it's pretty much useless.

hi,

i also tried this example. swt.jar is not a problem, but the .dll is
tricky. so i built a signed applet. i can download the .dll an call
System.load(..) but it doesn't work really.
here is my code:
------------------

public void init () {
String tmpDir = System.getProperty("java.io.tmpdir");
System.out.println("TempDir="+tmpDir);
location= tmpDir+"swt-win32-3063.dll";

try {
System.load(location);
System.out.println("library loaded");
}
catch (UnsatisfiedLinkError ule) {
System.out.println("dll not found -> download");
if (!GetFile.get( "http://localhost:8080/files/swt-win32-3063.dll",
tmpDir)){
System.out.println("Error downloading file!");
return;
}
try {
Runtime.getRuntime().loadLibrary(location);
}catch (UnsatisfiedLinkError ule2) {
System.out.println("dll not found after download");
System.out.println("Location:"+location);
ule2.printStackTrace();
return;
}
}
// the code frome snippet Snippet157
Thread thread = new Thread (new Runnable () {
public void run () {
setLayout(new java.awt.GridLayout (1, 1));
awtParent = new java.awt.Canvas ();
add (awtParent);
display = new org.eclipse.swt.widgets.Display ();
<------- here comes an error ... :
Caused by: java.security.AccessControlException: access denied
(java.util.PropertyPermission swt.version read)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)



and the html file:
-------------------

<HTML>
<HEAD>
<TITLE>...</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF">
<APPLET code="WordAppletApp.class" NAME="WordApplet" WIDTH="670"
HEIGHT="540" ALIGN="bottom" archive="sWordApplet.jar,swt.jar">bla</APPLET>
</BODY>
</HTML>

any ideas? any help? how do i include and manage the .java.policy in
the signed .jar file?

THX!

I was able to do this some time ago...
May be you should also sign swt.jar

Perhaps repackage swt.jar to contain the dll? Then finding and loading the
dll should happen within the context of the jar file.
Caveat: I haven't really tried this out- I'm just guessing it might work.

didn't work ...
i included the .dll in the swt.jar and signed it ..
it also didn't work with any browser (thunderbird or IE), only with the
appletviewer with permission settings

i'm using java 1.5.0_01

any ideas?
