Looking for an alternative Java interpreter...

Posted on 1997-11-11

Are there any other reliable Java interpreters available for Win 95 aside from JavaSoft JRE 1.1?

I am having problems using a Java application with JavaSoft JRE 1.1.  The interpreter does not process security requests correctly on Win 95, whereas on the Macintosh it apparently works fine.

Any help would be appreciated.

I think the best way is to get Java Developers Kit
from Sun. It's free and it include interpreter.
(at least Java is a sun's trademark :)
http://java.sun.com/products/jdk/1.1/index.html
BTW, they have also Win32 Performance Pack
downloadable from this page.

But looks like JRE will be the same in JDK :(
May be Performance Pack will help :)

There are others from Symantec, Microsoft, SuperCede which come with their development environments, but they are not free.

I beleive the version of Java interpreter I currently have is Sun's 1.1.  If I am wrong, please clarify.

Thanks,

Yes, thanks.  I can see you confirmed this yourself.  I am wondering if the Performance Pack will help?

Thanks

This appears to be my only option, unless there is some way to tweak the Sun interpreter to correct the security fault.

Thanks very much for your comment.

I know of two free mainstream virtual machines:
   Kaffe : www.kaffe.org
   Microsoft's vm : you know the url

It may be that neither of these fit your bill.  You can find others at the Gamelan site  http://java.developer.com.

What is the problem with security requests?

Dear Noahc:

Sorry to have taken a while to respond.  Your answer was very much appreciated, and it MAY be helpful to me, but I have not yet been able to unzip the .TGZ file from Kaffe to try it.  I am downloading the demo version of WinZip as I write!

In the mean time, I thought I would answer your question as to the nature of the security problem.  Quite simply, the interpreter blows right by the request from the server for a login and password, and the page which comes up says "Unauthorized Access Denied" (approximately, this is not an exact quote).

If you would like, I can forward the code to you.  The package is a shareware web searcher/agent type application.  There is no way to attach a file here, so I have not attempted it.  Also, I will let you know how Kaffe works out, when I try it (next day or two).

Thanks

Noahc:

Just a quick update for you.  I managed to download and unzip Kaffe.  The Kaffe software is an _uncompiled_ Java interpreter in C which (as far as I can see from the discussion list) has not yet successfully worked under Windows '95.

Frankly, I am a bit confused by this as there appears to be only one version of the source code (I would expect there to be one version for each platform supported).  I have looked through the discussion archive for Win '95 info, and it appears to be weak.

Also, could you please clarify for me where on the Microsoft website I can find their Java interpreter?  It does not appear among the free downloads.  There is only a Java plugin for Windows Explorer.

Thanks

Dear entropie,

I'm sorry about kaffe - I have seen others discuss it favorably in the java newsgroup, but I haven't used it.  

The microsoft vm can be found at http://www.microsoft.com/java/vm.  You can also look at their SDK which has a java runtime also - .../java/sdk  If you do choose the Microsoft VM, though, you may then be tempted to use their non-standard features.  (but some are useful).

I think that there are other vm's at Gamelan.

If you would like, I could look at the offending snippet of code, but no guarrantees - there are miles to go before I feel like any kind of expert.
