Re: Issue with Classpath and Java on IBM i 7.1

In my opinion, there are several questions to be asked, and some concepts
you need to learn.

How are you calling the program that is failing now?

When it is called by the MCF job how will it be called?

I suggest setting up the environment from within a clp program, then
calling the Java program in the clp. It will need both the classpath and
a path set up.

The next section here is my back and forth e-mail to get it to work on my
Windows machine. After that I will show what I have done on my power server
to get it to run there as the intention is this will run within a
GoAnywhere MFT (Managed File Transfer) project.

Here is my conversation with apache.org <http://apache.org/>

Hi Gordon,

You need to add the file to the classpath and make your call differently.
Here's what I do:

copy all extra jar files to a lib subdirectory

the call:

java -Dsun.java2d.cmm=sun.java2d.cmm.kcms.KcmsServiceProvider -cp
"pdfbox-app-2.0.2.jar;lib/*" org.apache.pdfbox.tools.PDFBox ExtractImages
Maxfield.pdf


the "-D...." is for JDK8 and higher only. If you don't do it, PDFBox might
run slow.

@Maruan: I wonder if we should explain this somehow somewhere.

Thanks for that. I have downloaded the file into my server. But I am
still having problems. I am not a java programmer. I use java standalone
binaries like PDFBox as a tool to help with specific projects. I have used
it for quite a while to Extract Text. We take the text files and process
the data within with great success.

In this case I am trying to extract the TIFF image.

Currently I am trying to get it to work on my PC and not the server.

My java directory has the following files:

Directory of C:\java

2016-07-05 10:27 AM <DIR> .
2016-07-05 10:27 AM <DIR> ..
2016-06-30 07:44 AM 1,140,632 jai-imageio-1.1.jar
2016-06-16 12:55 PM 44,035 Maxfield.pdf
2016-06-09 03:04 PM 7,942,473 pdfbox-app-2.0.2.jar

Then I run the following to set my class path.

set CLASSPATH=C:\java

Then I run the PDFBox command to the extract the TIFF image.

java -jar pdfbox-app-2.0.2.jar ExtractImages Maxfield.pdf

This is what I get when I run the command.

Writing image: Maxfield-1
Jul 05, 2016 10:18:46 AM org.apache.pdfbox.tools.imageio.ImageIOUtil

SEVERE: Supported formats: JPG jpg bmp BMP gif GIF WBMP png PNG wbmp

Why is not finding the jai-imageio-1.1.jar file?

My guess it is something simple. I think my lack of understanding of
Java is causing the problem.

Thanks

Gordon

Thanks for the quick response. I have tried a couple of times to
find the jai_imageio.jar file to download to our server with no
success.
Where can you get this file to download?

Here is the CLASSPATH I set up.

Here is the command I run to extract the tiff image from the PDF file

Run Java Program (JAVA)

Type choices, press Enter.

Class file or JAR file . . . . . > '/java/PDFBox/pdfbox-app-2.0.2.jar'

This is what I get when I run the command.

So for some reason it is not finding the
/java/PDFBox/lib/jai-iamgeio-1.1.jar file.

What am I doing wrong?

Thanks in advance.
