jar -ring problems (think)
Riyaz Mansoor
i'v got a small app that works like this.
working_directory/app.jar
working_directory/modules/mod1.jar
working_directory/modules/mod2.jar
if i run the files contained in app.jar without jarring it works fine. but
if i run it from the jar i get the following error. any ideas? or do u need
more info?
thanx
riyaz

My guess is that you've got the JAI extension jar file in (say)
c:\JDK1.3.1\jre\lib\ext, but when you double click on a jar file it's
using c:\Program Files\JavaSoft\JRE\1.3.1\bin\java
Edit the file type in Windows Explorer and try again.

I've seen the problem many times before :)

There's one more thing - JRE's installer is "smart" and it installs
java.exe and javaw. exe in a location, where it it will always can be
found by PATH - it's the main directory of Windows. They're also using the
"wrong" classpath, and when you're running java.exe from a bach file, the
same problem appears. I always delete them to avoid that :)

Yes - that's effectively a link to the one in JavaSoft.

I prefer just to add a path entry to the JDK early on in the path,
myself...
