Opening a doc file with a Password

[Will Nye]

I have been looking through the examples on github and can't find one that uses a password protected document (opening from not saving as). Did I miss it? If not could any examples would be great! Thanks

[jason]

Hi, If you mean a password protected docx (as opposed to legacy binary doc), then OpcPackage contains a method:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

load(final java.io.File docxFile, String password)
 

Parsed in 0.014 seconds, using GeSHi 1.0.8.4

WordprocessingMLPackage extends OpcPackage

[Will Nye]

Thanks for your help Jason, I tried as you had mentioned but for some reason I am getting an error

Here is a class that I wrote and for some reason it is having troubles with setting wordMLPackage = (WordprocessingMLPackage)OpcPackage.load(new java.io.File(inputfilepath), "password");

Code: Select all

import org.docx4j.openpackaging.exceptions.Docx4JException;
import org.docx4j.openpackaging.packages.OpcPackage;
import org.docx4j.openpackaging.packages.WordprocessingMLPackage;
import java.io.File;


public class Testclass {

public void readFromdoc(){
//   JAXBContext context = org.docx4j.jaxb.Context.jc;
   
   String inputfilepath = System.getProperty("user.dir") + "\\" + "mytest.docx";
   System.out.println(inputfilepath);          


   // Load the docx
   WordprocessingMLPackage wordMLPackage=null;
   try {
      wordMLPackage = (WordprocessingMLPackage)OpcPackage.load(new java.io.File(inputfilepath), "password");
   } catch (Docx4JException e1) {
      System.out.println("Unable to call load method from OpcPackage");
      e1.printStackTrace();
      System.exit(0);
   }
   // Save it
   String outputfilepath = System.getProperty("user.dir") + "/OUT_OpenAndSaveRoundTripTest.docx";
   try {
      wordMLPackage.save(new File(outputfilepath));
   } catch (Docx4JException e) {
      System.out.println("Unable to output file");
      e.printStackTrace();
      System.exit(0);
   }
}
   
}

Here is what my console output looks like

my user directory\mytest.docx

I downloaded the log4j.jar file and imported it just to see if that would make a difference but it still isn't compiling. Any advice would be great, thanks again.

[jason]

So what happens when you add log4j to your classpath?

[Will Nye]

Sorry for the delay in response. After importing apache.* I still am getting the following issue.

You need to add the log4j jar to your classpath. Are you doing this in an IDE? In any case, Google how to do that

[Will Nye]

I downloaded the log4j jar file and added it to the class path. I was just using org.apache.* to be sure anything that needed to be imported was. I did add it to the build path. Also, I'm using eclipse, would that make any difference?

[jason]

Eclipse is fine, but log4j is not on the classpath for the relevant "run configuration" if you are getting that error. You need to add it.

[Will Nye]

Jason, sorry for asking but do you know what could be causing the log4j:WARN No appenders could be found for logger (org.docx4j.openpackaging.io.LoadFromZipNG) error?

http://stackoverflow.com/questions/1813 ... erly-issue

The password for the file is t3mpw0rdh0undpw0rd (my docx file I'm attempting to read from)

Thanks again!

[jason]

You've got log4j on your classpath, which is good; you now need log4j.properties or log4j.xml on your classpath.

In Eclipse, in your run configuration, you can add the folder containing that file to your build path. (Classpath tab, click User Entries, then click advanced)

While you are there, on the arguments tab, under VM arguments, make sure you have

-Dlog4j.configuration=log4j.xml

For an actual log4j config file, see https://github.com/plutext/docx4j/blob/ ... /log4j.xml

Finally, not sure whether you've seen http://stackoverflow.com/questions/1813 ... erly-issue (post by a different username, but same issue, and same password), but that user was trying to open an OpenOffice/LibreOffice file, not an OpenXML file...

[Will Nye]

Thanks, that was the issue. I downloaded MS office and saved it in word. For some reason there was an issue using open office when saving as a docx file. However, I am still unable to read from a password protected document following the same format you had suggested load(final java.io.File docxFile, String password).

Here is the code snippet and what the console displays

String inputfilepath = System.getProperty("user.dir") + "\\" + "test.docx";


// Load the docx
WordprocessingMLPackage wordMLPackage=null;
try {
wordMLPackage = (WordprocessingMLPackage)OpcPackage.load(new java.io.File(inputfilepath), "t3mpw0rdh0undpw0rd");
} catch (Docx4JException e1) {
System.out.println("Unable to call load method from OpcPackage");
e1.printStackTrace();
System.exit(0);
}

You didn't attach your docx, but in any case, your problem is that you are missing another dependency!

docx4j won't work if dependencies are missing from your classpath

If you are using 2.8.1, you should include all the files in http://www.docx4java.org/docx4j/docx4j-2.8.1/

Your immediate problem here is that you are missing poi*.jar

[Will Nye]

Thanks so much for your patience, I was able to read from an encrypted docx file.

If anyone is curious how I did it for future reference.

I downloaded apache's common/codec jar and like Jason said the poi.jar file

Added them to the build path. My class to read from a password protected docx file looks like this:

import org.docx4j.openpackaging.exceptions.Docx4JException;
import org.docx4j.openpackaging.packages.OpcPackage;
import org.docx4j.openpackaging.packages.WordprocessingMLPackage;
import org.docx4j.openpackaging.parts.WordprocessingML.AltChunkType;
import org.docx4j.openpackaging.parts.WordprocessingML.MainDocumentPart;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.util.List;




public class Testclass {

public void readFromdoc(){

String inputfilepath = System.getProperty("user.dir") + "\\" + "yourDocument.docx";


// Load the docx
WordprocessingMLPackage wordMLPackage=null;
try {
wordMLPackage = (WordprocessingMLPackage)OpcPackage.load(new java.io.File(inputfilepath), "yourPassword");
} catch (Docx4JException e1) {
System.out.println("Unable to call load method from OpcPackage");
e1.printStackTrace();
System.exit(0);
}
MainDocumentPart main = wordMLPackage.getMainDocumentPart();
try {
main.addAltChunk(AltChunkType.WordprocessingML, new FileInputStream(inputfilepath) );
} catch (FileNotFoundException e) {
System.out.println("File not found");
e.printStackTrace();
System.exit(0);
} catch (Docx4JException e) {
System.out.println("Docx4JException");
e.printStackTrace();
System.exit(0);
}
List<Object> content = main.getContent();
System.out.println(content.get(0));
}

}
