Re: Question about running a Java Class

Hi Jack,

The message says it can't find a logging class. If you look at:

http://pdfbox.apache.org/dependencies.html

you'll see it depends on some other items. The download page:

http://pdfbox.apache.org/download.html

leads me to believe that

pdfbox-app-1.6.0.jar 9.8MB, pre-built standalone binary

probably has everything you need, but I expect it needs to be run as an
executable jar so it can use the manifest for dependencies. That's my best
guess. I haven't used pdfbox and don't have the free time to go through the
process.

If I try it like this without the extra quotes, I see a different message
JAVA CLASS('org.apache.pdfbox.PDFBox') PARM('ExtractText /tmp/CONS.PDF' )
CLASSPATH('/JavaPDF/pdfbox-1.6.0.jar')

I expecty It doesn't recognize 'ExtractText /tmp/CONS.PDF' as any known argument and just exits.


Also, you asked:

Is there any advantage to using the JAVA command instead of QSH?

Clarity, IMO. QSH just takes a CMD keyword. In the normal case for
running/submission with variables, you can end up with something like this:

CHGVAR VAR(&CMDVAL) VALUE(&STRVAL *TCAT &SPACE *CAT +
&USER *TCAT &SPACE *CAT &DASHPWD *TCAT +
&SPACE *CAT &PASS *TCAT &SPACE)
QSH CMD(&CMDVAL)

That's from production code. While I had a reason to make that one obscure,
normally the CL command with individual keywords/parameters will be much
clearer to those who come after (and possibly yourself later).

Good Luck!

Thanks for the reply.

I tried this but it didn't work. It seemed to get further, but I think it
might not be finding the PDF

JAVA CLASS('org.apache.pdfbox.PDFBox') PARM('ExtractText' '/tmp/CONS.PDF'
'/tmp/cons.txt' ) CLASSPATH('/JavaPDF/pdfbox-1.6.0.jar')

Hi Jack,

David's answer is close but I wouldn't expect it to work as is. The
reason is that "ExtractText" and "cons.pdf" are separate arguments or
parameters. IOW, using your doc example:

usage: java -jar pdfbox-app-x.y.z.jar ExtractText [OPTIONS] <PDF file> [Text

file]

everything after the jar are arguments, including the ExtractText "command".

So, for JAVA/RUNJVA use PARM( 'ExtractText' 'cons.pdf' ), add any other
arguments as necessary.

If you run the jar as executable, your classpath should just need to be
"/JavaPDF". If you run the class as in the example, your classpath should
be "/JavaPDF/pdfbox-1.6.0.jar". The reason is that an executable jar has
its entry point (class to load) defined in the manifest.

HTH,

I was able to get the extract to work on my PC using this command.
Can anyone help me "convert" the syntax to Iseries?

Try this:

qsh cmd('java -cp pdfbox-app-1.6.0.jar org.apache.pdfbox.PDFBox
ExtractTextcons.pdf')

or this:

JAVA CLASS('org.apache.pdfbox.PDFBox') PARM('ExtractTextcons.pdf')
CLASSPATH('pdfbox-app-1.6.0.jar')
