EDI Must be a minimum of 1 instances of segment [UNS]

Am newbie to EDI. And i just converted the ORDERS edi file to XML using smooks api. Some of the ORDER example files are working fine in following example. But i got the following exception when i running the following edi file. Am stuck with this. Here is my example and EDI data
package example;
import org.json.JSONObject;
import org.json.XML;
import org.milyn.Smooks;
import org.milyn.SmooksException;
import org.milyn.io.StreamUtils;
import org.milyn.smooks.edi.unedifact.UNEdifactReaderConfigurator;

import java.io.FileInputStream;
import java.io.IOException;
import java.io.StringWriter;
public class Main {
public static int PRETTY_PRINT_INDENT_FACTOR = 4;
protected static String runSmooksTransform() throws IOException, SAXException, SmooksException {
Smooks smooks = new Smooks();
smooks.setReaderConfig(new UNEdifactReaderConfigurator("urn:org.milyn.edi.unedifact:d93a-mapping:*"));
try {
StringWriter writer = new StringWriter();
smooks.filterSource(new StreamSource(new FileInputStream("EDI.edi")), new StreamResult(writer));
return writer.toString();
} finally {
smooks.close();
}
}
public static void main(String[] args) throws IOException, SAXException, SmooksException {
System.out.println("\n\n==============Message In==============");
System.out.println(readInputMessage());
System.out.println("======================================\n");
String messageOut = Main.runSmooksTransform();
System.out.println("==============Message Out=============");
System.out.println(messageOut);
System.out.println("======================================\n\n");
JSONObject xmlJSONObj = XML.toJSONObject(messageOut);
String jsonPrettyPrintString = xmlJSONObj.toString(PRETTY_PRINT_INDENT_FACTOR);
System.out.println(jsonPrettyPrintString);
}
private static String readInputMessage() throws IOException {
return StreamUtils.readStreamAsString(new FileInputStream("EDI.edi"));
}
}
And the exception with Sample EDI Data
Exception in thread "main" org.milyn.SmooksException: Failed to filter source.

Bad source data will cause this.
It looks like smooks is looking for a UNS segment which isn't in your data. The section control is mandatory per the D.93A standard.

Convert docx file to pdf in java..issue

I am developing a project which needs a docx file to be converted to pdf. I found same question already posted and used the code which was provided by "Kishan C S". It uses docx4J2.8.1
The code is working fine , pdf is generated but only problem I am facing is that the docx file contains logo.jpg (images header part) which are not converted. Only textual format is converted to pdf.
I am posting the code which I have used. Please let me know what how can I solve the problem
P.S: link I referred Convert docx file into PDF with Java

Java using iText and Extracting from PDF

I followed some previous advice on StackOverflow here (Extract specific parts of PDF documents) to extract data from PDFs. I have limited programming experience and virtually none with Java (used C++ when I was younger).
After overcoming some newbie difficulty having the right jars available via the buildpath, I have run into what seems to be a define problem. I hope this isn't a stupid question, I've tried for quite some time to get this to work.
Here's the error I receive:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The constructor RegionTextRenderFilter(Rectangle) is undefined
at PDFExtract.PDFExtract.parsePdf(PDFExtract.java:41)
at PDFExtract.PDFExtract.main(PDFExtract.java:59)
Here is my code:
package PDFExtract;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.PrintWriter;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Rectangle;

import com.itextpdf.text.pdf.parser.RenderFilter;
import com.itextpdf.text.pdf.parser.TextExtractionStrategy;
public class PDFExtract {
/** The original PDF that will be parsed. */
public static final String PREFACE = "resources/pdfs/preface.pdf";
/** The resulting text file. */
public static final String RESULT = "results/output.txt";
/**

* #param pdf the original PDF

* #throws IOException
*/
public void parsePdf(String pdf, String txt) throws IOException {
PdfReader reader = new PdfReader(pdf);
PrintWriter out = new PrintWriter(new FileOutputStream(txt));
Rectangle rect = new Rectangle(70, 80, 420, 500);
RenderFilter filter = new RegionTextRenderFilter(rect);
TextExtractionStrategy strategy;
for (int i = 1; i <= reader.getNumberOfPages(); i++) {
strategy = new FilteredTextRenderListener(new LocationTextExtractionStrategy(), filter);
out.println(PdfTextExtractor.getTextFromPage(reader, i, strategy));
}
out.flush();
out.close();
reader.close();
}
/**
* Main method.
* #param args no arguments needed
* #throws DocumentException
* #throws IOException
*/
public static void main(String[] args) throws IOException, DocumentException {
new PDFExtract().parsePdf(PREFACE, RESULT);
}
}
The error appears on this line "RenderFilter filter = new RegionTextRenderFilter(rect);"
Hopefully someone can help me! Again I apologize if this is a stupid question. I tried jumping from a Hello World to this and it's taxing my aged understanding of C++

so here i think font getting problem here,please tell me what exactly i do?

Most of the CSS is not supported by itext's XML worker.
Since bootstrap contains very advanced CSS, this is pretty much doomed...
You'll need to write your own CSS file with very limited styling compared to bootstrap
Edit:

How to display iText Image object in java

I am creating a PDF reader in java. For reading PDF files i am using iText library. I have a sample code to read the PDF files but i don't know how to display the iText Image object in a JFrame.Below is the code to read a PDF file.
import java.io.FileOutputStream;
import java.io.IOException;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Image;
import com.itextpdf.text.pdf.PdfImportedPage;
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.PdfWriter;
public class ReadAndUsePdf {
private static String INPUTFILE = "c:/temp/FirstPdf.pdf";
private static String OUTPUTFILE = "c:/temp/ReadPdf.pdf";
public static void main(String[] args) throws DocumentException,
IOException {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document,
new FileOutputStream(OUTPUTFILE));
document.open();
PdfReader reader = new PdfReader(INPUTFILE);
int n = reader.getNumberOfPages();
PdfImportedPage page;
// Go through all pages
for (int i = 1; i <= n; i++) {
// Only page number 2 will be included
if (i == 2) {
page = writer.getImportedPage(reader, i);
Image instance = Image.getInstance(page); //how to show this object in a JFrame
document.add(instance);
}
}
document.close();
}
}

I have the exactly same problem, and I solved it by using ICEPdf to render the PDF in Swing, and iText to manipulate it.
Possible duplication: Can I use iText to render PDF in my Swing application?
