Read A PDF and Populate the data on Form

[Snajay]

I have a requirement.I need to read a pdf  and populate its data on a form. I created a Java App which is using external Java API(IText) to read a PDF File and deployed its Jar file(Both Java App and External API) to mid server. After that, I created a ECC Que and tried to call that java App. I am able to call a normal function of that java app but i am not able to call that function which is reading the PDF File. So does servicenow allow to use external Java API Deployed at mid server?  Here is My Code :

Java Code

package com.midserver;

import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.parser.PdfTextExtractor;
import java.io.IOException;

public class ReadData
{
    public String getData()            //I am not able to call this method
    {
        PdfReader reader;
        String textFromPage="";

        try {

            reader = new PdfReader("c:/demo.pdf");

            // pageNumber = 1
            textFromPage = PdfTextExtractor.getTextFromPage(reader, 1);

          //  System.out.println(textFromPage);

            reader.close();

        } catch (IOException e) {
            e.printStackTrace();
        }
        return textFromPage;
    }
    
}

ECC que(output) :

<parameters>
    <parameter name="script" value="var v1 = new Packages.com.midserver.ReadData();v1.getData();"/>    
    
</parameters>

ECC Que(Input):

<?xml version="1.0" encoding="UTF-8"?><results error="Caused by error in JavaScript probe 'JavascriptProbe' at line 1&#10;&#10;==&gt;   1: var v1 = new Packages.com.midserver.ReadData();v1.getData();&#10;" probe_time="0" result_code="900000"><result error="Caused by error in JavaScript probe 'JavascriptProbe' at line 1&#10;&#10;==&gt;   1: var v1 = new Packages.com.midserver.ReadData();v1.getData();&#10;"><output>Evaluation error: Caused by error in JavaScript probe 'JavascriptProbe' at line 1
