Words.Aspose for Java crashes on RHEL Linux when converting Word Doc to TIF

scott.kresge 2017-09-08 15:55:39 UTC #1

We are attempting to open a Word Doc and convert it to TIF using Apose.Words for Java with little luck.

Code Snippet:

/* Convert the document */
Document wordDoc = new Document(serverFilePath);

String convertedfileExtension = “.TIF”;

String convertedFilename = “12345678” + convertedfileExtension;

String convertedServerPath = “/home/user/” + convertedFilename;

/* Attempt to convert the document to the destination format */
try {
if (convertedfileExtension.equals(".TIF")) {
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.TIFF);
options.setTiffCompression(TiffCompression.CCITT_4);
options.setResolution(300);

	wordDoc.save(convertedServerPath, options);
}

…

This code is executed from a fat Jar File. When executing it on the RHEL server, it crashes with the below stacktrace:

We are using a Linux server with Red Hat Enterprise Linux Server release 6.6 (Santiago) and Oracle Java JDK 1.7.40.
We are using aspose-words-17.8-jdk16.jar for the TIF conversion.

We have tried explicitly adding the following fields to our Manifest without luck:
Specification-Title
Specification-Version
Specification-Vendor
Implementation-Title

@scott.kresge,

Have you tried the latest version of Aspose.Words for Java i.e. 17.9?

In case the problem still remains, please ZIP and attach your input Word document you are getting this problem with here for testing. We will investigate the issue on our end and provide you more information.

scott.kresge 2017-09-11 14:02:13 UTC #3

@awais.hafeez,

We updated to 17.9 this morning and it still fails with the same error. Attached is a zip containing a document that fails. It appears that only documents with images in them fail. Unfortunately, all of the documents that we will need to convert will have some sort of image in them. test_document.zip (180.4 KB)

awais.hafeez 2017-09-12 04:40:42 UTC #4

@scott.kresge,

Please install JAI to correctly render to TIFF images with Aspose.Words for Java:

System Requirements
Installing the native JAI and ImageIO

scott.kresge 2017-09-12 11:08:29 UTC #5

@awais.hafeez,

We did follow the steps for Installing native JAI on Linux. The library will not allow TIF conversion without these. It returns a specific error if they are not installed.

Per the provided instructions we have placed:
jai_codec.jar, jai_core.jar, jai_imageio.jar, clibwrapper_jiio.jar, and mlibwrapper_jai.jar under $JAVA_HOME/jre/lib/ext/
libclib_jiio.so and libmlib_jai.so under $JAVA_HOME/jre/lib/amd64/

We used the libraries from the Aspose site. They are the ones that are failing.

awais.hafeez 2017-09-13 05:01:15 UTC #6

@scott.kresge,

After an initial test with Aspose.Words for Java 17.9, we were unable to reproduce this issue on our end. We tested by configuring JAI (see Installing Native JAI and ImageIO on Linux) on a fresh Ubuntu 12.04 LTS (i386) VM. Our test Java version was java-7-oracle (32-bit 1.7). What Java version are you currently using?

scott.kresge 2017-09-13 10:39:00 UTC #7

@awais.hafeezm

We are using Oracle Java 1.7.40 64 bit.

awais.hafeez 2017-09-14 03:06:55 UTC #8

@scott.kresge,

We will prepare the required platform to simulate the environment as that of yours. As soon as everything is setup, we will test your scenario and post the results here for your kind reference. We apologize for any inconvenience.

awais.hafeez 2017-09-18 06:07:33 UTC #9

@scott.kresge,

We have tested your scenario over 64-bit Ubuntu 16.04.3 LTS by using Oracle Java 1.7.40 (64-bit) but I am afraid we are still unable to reproduce this issue with Aspose.Words for Java 17.9 on our end. Can you please try creating a standalone Java console application and list the steps here for our reference to reproduce the same issue on our end? Thanks for your cooperation.

scott.kresge 2017-09-18 17:16:13 UTC #10

@awais.hafeez,

I have created a standalone java console application. It contains only the Aspose.Words 17.9 dependency. This simple program still fails convert a Word Doc to Tiff on our server. I attempted to attach is a zip of the jar, our test document, and the Java code behind it. It will not upload.

Below is our Java version and paths to the JAI libraries. Please review and let us know if we are missing anything.

@awais.hafeez,

I create a new Eclipse project named asposedemo with package asposedemo.
Inside the package is Demo.java and Aspose.Words.lic.
I created a libs folder with aspose-words-17.9-jdk16.jar file.
I added the Aspose jar to the build path.

Demo.java Contents:
package asposedemo;

import java.io.File;
import java.io.InputStream;

import com.aspose.words.Document;
import com.aspose.words.ImageSaveOptions;
import com.aspose.words.License;
import com.aspose.words.SaveFormat;
import com.aspose.words.TiffCompression;

public class Demo {

	public static void main(String[] args) {
		String filePath = null;
		String fileName = null;
		
		/* Validate Arguments */
		try {
			if (args.length == 2) {
				filePath = args[0].toString();
				fileName = args[1].toString();
			} else {
				throw new Exception();
			}
		} catch (Exception e) {
			System.out.println("Invalid Number of Command Line Arguments provided (expecting 3 arguments and received " + args.length + ")." );
			System.out.println("Argument 1: File Path");
			System.out.println("Argument 2: File Name");
			System.out.println("Exiting...");
			System.exit(1);
		}
		
		/* Load and verify the Aspose.Words License */
		License license = new License();
		String licenseFile = "Aspose.Words.lic";

		try {
			InputStream is = Demo.class.getResourceAsStream(licenseFile);
			license.setLicense(is);
		} catch (Exception le) {
			System.out.println("Error loading specified license file '" + licenseFile + "' with Exception" + le);
			System.out.println("Exiting...");
			System.exit(1);
		}
		
		/* Exit if the Library is not licensed to avoid conversion of only the first X pages */
		if (!license.isLicensed()) {

		    System.out.println("Error Aspose.Words is not Licensed!");
			System.out.println("Exiting...");
			System.exit(1);
		} else {
			System.out.println("Successfully loaded licenses.");
		}
		
		
		try {
			String serverFilePath = filePath + fileName;
			
			boolean exists = validateFile(serverFilePath);
			if (!exists) {
				throw new Exception("File '" + serverFilePath + "' does not exist.");
			} else {
				System.out.println("Successfully found File '" + serverFilePath + "'.");
			}
			
			/* Convert the document */
			Document wordDoc = new Document(serverFilePath);
			
			String convertedFilename = fileName.substring(0, fileName.lastIndexOf('.')) + ".TIF";
			
			String convertedServerPath = filePath + convertedFilename;
			
			try {

				ImageSaveOptions options = new ImageSaveOptions(SaveFormat.TIFF);
				options.setTiffCompression(TiffCompression.CCITT_4);
				options.setResolution(300);
				
				wordDoc.save(convertedServerPath, options);
				
				System.out.println("Converted " + serverFilePath + " to " + convertedServerPath +".");
								
			} catch(Exception e) {
				throw new Exception("Failed to convert Document " + serverFilePath + " from Word Doc to .TIF with error " + e.toString() + "!");
			}
	
			
		} catch (Exception e){
			System.out.println("Error occurred when processing File '" + fileName + "' Message:" + e);
		}
	}
	
	public static boolean validateFile(String filePath) {
		boolean exists = false;
		
		// Check that file is available.
		File file = new File(filePath);
		if (file.exists() || !file.isDirectory()) { 
			exists = true;
		}
		
		return exists;
	}

}

I then create a runnable jar file using Ant. The build.xml is below:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<project default="create_run_jar" name="Create Runnable Jar for Project asposedemo with Jar-in-Jar Loader">
    <!--this file was created by Eclipse Runnable JAR file Export Wizard-->
    <!--ANT 1.7 is required-->

Next I upload the Jar file to the server and try to run it using the Word Doc originally provided.

@scott.kresge,

Thanks for the additional information. Do you only observe this exception with one particular document (234299552.DOCX) or every document you try to convert to TIFF causes the same exception on your end? Do you have any other machine you can test the same scenario on? Also, if you are unable to upload your project here, please ZIP and upload your test project to Dropbox and share the download link here for further investigation.

@awais.hafeez,

We observe this behavior with any document that contains an image (i.e. JPEG, PNG, etc.). All of the documents that we need to convert follow the same template. The last page will always be an image. The document I provided to you was just a test document we created to give you a sample to work with. I will work on trying to get you a copy of the project. The demo project is extremely simple. See attached screenshot.

@awais.hafeez,

Can you provide me a email address I can send the files to? We can’t use Dropbox. We have a secure file transfer protocol we can use to get you the zip of the project.

@awais.hafeez,

We have tried this on multiple servers with the same issue. We have also tried OpenJDK as an alternate Java and still see the problem. We have tried 64bit and 32bit Java and it still fails with both. We are running out of things to try on our end. Do you have any suggestions? Can you review where we placed the JAI libraries and how we are building the Jar file? The project we planned on using this for is currently in UAT and this is holding up our testing currently.

@scott.kresge,

Please send your Project and runnable JAR to the following email:
awais.hafeez@aspose.com

@awais.hafeez,

You should have received a download email with a zip named FileConversionDemo.zip. Please let us know if you need anything further. I can provide files through email that are larger than the 3MB file upload size in the forum.

awais.hafeez 2017-09-21 04:07:20 UTC #18

@scott.kresge,

We have received FileConversionDemo.zip. We are working over your query and will get back to you soon.
