Hey ppl,

Hoping you java guru's can help a fella out.
I'm still relatively new to java and still have a lot to learn.

My Issue:
The app I am trying to interface with name is pdfcompress.jar:
I can access it via creating my own html interface.




-- The above code then takes me through a manual interface for uploading etc.
However I would like to interact with this .jar file via my own app.
i.e. parse, the location & name of the to be compressed pdf + the dir & name where it will be
"exported to" aswell, and just add the directory for the log File.

I decided let me try use the command line first.
I tried using the command line but was unsuccessful (compress is the documented method to use).

java –jar "C:\pdfcompress.jar" compress "C:\toobig.pdf" "C:\just_right.pdf" "C:\"

I get the following error:


C:\>java -jar "C:\pdfcompress.jar" compress "C:\toobig.pdf" "C:\just_right.pdf" "C:\"
Exception in thread "main" java.lang.NoClassDefFoundError: ûjar


Help would be greatly appreciated

Welcome to the Ranch
I have broken some of the long lines and deleted some blank lines to improve legibility in your post. Don’t use tabs for indenting; use spaces.
That doesn’t look like Java™ code, but JavaScript, so I shall move you to the JavaScript forum.
What happens if you run that applet with appletviewer on its own, apart from the rest of the programming?

the thing above the 'u' in ujar, is that a problem with the site or does the compress.jar has some other dependency which can't be found?

Thanks for the welcome ;)

What happens if you run that applet with appletviewer on its own, apart from the rest of the programming?
- The applet seems to run perfectly fine, it then takes me through all the convert options etc; hence I know the program is working.
- P.s Wont use those indentations again ty for the edit and move to the correct forum.

The thing above the 'u' in ujar, is that a problem with the site or does the compress.jar has some other
dependency which can't be found?
- I have no idea, the pdfcompress.jar from its documentation says it can be ran from a command line and when
I entered it into the format as seen bellow that error occurred .

Here is the "syntax" they tell me to run in the command line:

Moved to the Applets forum.
 
It is sorta covered in the JavaRanch Style Guide.
