Issue with Classpath and Java on IBM i 7.1

I am trying to get PDFBox from apache.org <http://apache.org/> to run with a TIFF image extraction jar file from another organization. It is supposed to work with PDFBox. I got it to work on my computer which is a Windows 10 machine.

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: No ImageWriter found for 'tiff' format Jul 05, 2016 10:18:46
AM org.apache.pdfbox.tools.imageio.ImageIOUtil writeImage
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 file structure for the jar files on my power server.

Here is the CLASSPATH I set up.

Display Environment Var (*JOB)

Name . . . . . . . . . : CLASSPATH


Value . . . . . . . . . : '/java/PDFBox/lib/jai-iamgeio-1.1.jar'


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'

Parameters . . . . . . . . . . . > ExtractImages



+ for more values > '/java/PDFBox/Maxfield.pdf'



Classpath . . . . . . . . . . . *ENVVAR

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.
