#6 Decompiler is throwing an IOException

I have installed everything correctly. Whenever I try to
open a .class file in Websphere, I get an IOException.
I ran the same command from the dos prompt and jad
worked just fine. I am thinking it is somehow unable to
get permissions to my folder or something.

Here is the stack trace:

Beta release 2.06 has only been tested W2K, Eclipse R2.1
and Jad v1.5.8.e.

It has not yet been ported to Eclipse 3.0M?

I have not been able to recreate the problem.
I need some more information about your environment:
* OS Version
* JDK/JRE
* Eclipse version
* JAD Version
* Is JAD in your environmert PATH?

I understand you have not ported it to 3.0M3 yet, but I was
hoping...

* OS Version
XP SP1 +all security fixes
* JDK/JRE
j2sdk1.4.2_1
* Eclipse version
3.0M3
* JAD Version
Jad v1.5.8e2.
* Is JAD in your environmert PATH?
No, it has been configured in. But it makes no differences

I shure have some problems porting to 3M3 I will try to give
progress information in Feature Requests item #800244.

I am also working with some new features for JadClipse and
they are being tested with 3M3 and i have not seen your
problem, which worries me a little.

Will you give me the exact scenario:
* From where do you select the .class file?

I can provoke the problem is several different ways, the
easiest being just selecting the a .class with no
corresponding .java file in the package explorer.

I currently run j2sdk1.4.2_1 and eclipse-I20030917 if that
matters -- but I have observed the problem with other
combinations as well. And I use XP SP1.

I am puzzled, I have almost the same configuration, have you
seen this work with Eclipse 2.?

Honestly I can't say, though I can test it in a couple of days.

I have only lately started to use the jadclipse in a project
where the provided jar file occationally misbehaves and I need
more insight as to the exact working of the involved classes...
And I don't have the sources!

We faced the same problem here, but the easy solution
seems to add jad.exe somewhere into you PATH!

Hi "nobody",

I tried to add jad.exe to my PATH, but to no avail...

Hi tonny,

it worked for us,

only left thing i can think of is to be sure about
that there is no space in the path to jad.

good luck

I have put jad in "C:\Program Files\Java\jad.exe", so yes
there are spaces in the name. It works from the command line
AFAIK, but I'll try putting it elsewhere and lso to use oldstyle
names for it in eclipse.

this problem is odd and seems to be related to having spaces
within the JAD path. I have set JadClipse to find jad
at "c:\program files\eclipse\plugins\jadclipse\jad.exe" and this
error comes intermidently. I have then set the path
to "c:\progra~1\eclipse\plugins\jadclipse\jad.exe" and it goes
away only after shutting down eclipse and bringing it back
up.

I also noted that if I have the wrong JAD path in the
JadClipse settings and open a file, it gives me the JadClipse
error of not being able to create the process, however it
seems that JadClipse plugin caches these values because
subsequent files do not obtain this error only the ones
previously opened.
