Reading text using PDFBOX

[umadas]

Hi Ranchers

I am using PDFBox to read the text from the PDF file and display the x-y cordinates of each character.For simple file it works fine.But when i have a pdf file containing text in different fonts,tables,graphs etc.The output is somewhat jumbled like it reads first two paragraphs ,then last paragraphs then third para.Also the text written vertically is not read property ,for example market is read as "mark" and then in next line it prints "et".Is there any solution.?Kinldly help

Thanks

Hi,

please use the below code to read the pdf file and it worked fine for me. (i was able to read entire pdf text).

PDDocument pddDocument=PDDocument.load(new File("a.pdf"));
PDFTextStripper textStripper=new PDFTextStripper();
System.out.println(textStripper.getText(pddDocumen t));
pddDocument.close();


For the above code supporting jar files are:
pdfbox-0.8.0-incubating.jar
fontbox-0.8.0-incubating.jar
commons-logging-1.1.1.jar

Hi,
im trying the same(above code n jar).
Im gtng da error as in title.Hw to resolve te issue.10-07 12:43:42.456: ERROR/AndroidRuntime(18616): java.lang.NoClassDefFoundError: org.apache.pdfbox.pdmodel.PDDocument

if you are getting this error: java.lang.NoClassDefFoundError: org.apache.pdfbox.pdmodel.PDDocument, it means the particular jar file is not recognised or not set in the classpath. java.lang.NoClassDefFoundError is due to the class file is not found during runtime.

You should also check with the newest version of jar file (here you have 0.8 as the version). And also i see the error message containing AndroidRuntime, so make sure you configure all the jar files in the Eclipse IDE while running your Android App.

If you have any doubts, you can reply to me..always welcome :)

Is pdf box 1.3 is the latest version?

[chiru]

Could not find class 'org.apache.pdfbox.pdmodel.PDDocument', referenced from method org.apache.pdfbox.pdfparser.PDFParser.getPDDocumen t.I tried with pdf box 1.2.1.common log 1.1.1 and font box 1.2.1..still it is showing the above error..

Hi Chiru,

I re-tested the code, and is working fine. Please check out what i have written:

import java.io.File;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.util.PDFTextStripper;

public class PdfBoxTest
{
public static void main(String args[])
{
try
{
PDDocument pddDocument=PDDocument.load(new File("a.pdf"));
PDFTextStripper textStripper=new PDFTextStripper();
System.out.println(textStripper.getText(pddDocumen t));
pddDocument.close();
}
catch(Exception ex)
{
ex.printStackTrace();
}
}
}

In the classpath, i have included the following jar files:
1) pdfbox-1.2.1.jar
2) fontbox-1.2.1.jar
3) commons-logging-1.1.1.jar

I am not sure about the latest version of pdfbox, i guess it should be 1.2.1. The error that your are getting is probably the jar file not being set in the classpath, as the exception is purely related to inability to find the class file, it means the jar file is not being located at that location. Rest of the things will go fine if your jar file is properly recognized.
