I have the following error: Content not allowed in Prolog** I have two methos, one called from main and another from button event handler. One method read the rdf file and another create individual of Student class based on name entered by users in a text field.
What is the expected error.
My code is:

JOptionPane.showMessageDialog(null, janeSmith.toString());
try {

FileWriter out=new FileWriter(file);
} catch (IOException ex) { Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex);
}
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
OntModel model=ModelFactory.createOntologyModel();
String str=jTextField2.getText();
read1(str, model);
}
And finally main()

I am trying to convert a .prn file to html. But due to file format, I am not able to parse in a way I want.
I tried many approaches. some of are:
package main;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
public class PrnToHtml {
public static void main(String[] args) {
try (BufferedReader reader = new BufferedReader(new FileReader(".\\Workbook2.prn"));
FileWriter writer = new FileWriter("output_prn.html")) {
writer.write("<html><body><h3>PRN to HTML</h3><table border>\n");
String currentLine;
while ((currentLine = reader.readLine()) != null) {
writer.write("<tr>");
for(String field: currentLine.split("\\s{2,}")) // "\\s{2,}"
writer.write("<td>" + field + "</td>");
writer.write("</tr>\n");
}
writer.write("</table></body></html>\n");
} catch (IOException e) {
e.printStackTrace();
}
}
}
Output of this will be html page looks like this:
prn file\data looks like this:
Other this I tried to read this is:
package main;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.net.URISyntaxException;
import java.nio.file.Files;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import java.util.stream.Collectors;
import java.util.stream.Stream;
public class PRNToHtml {
private static final String DILIM_PRN = " ";
private static final Pattern PRN_SPLITTER = Pattern.compile(DILIM_PRN);
public static void main(String[] args) throws URISyntaxException, IOException {
try (#SuppressWarnings("resource")
Stream<String> lines = new BufferedReader(new FileReader(".\\Workbook2.prn")).lines()) {
List<String[]> inputValuesInLines = lines.map(l -> PRN_SPLITTER.split(l)).collect(Collectors.toList());
for (String[] strings : inputValuesInLines) {
for (String s : strings) {
System.out.print(s.replaceAll("\\s+", "") + " ");
}
System.out.println();
}
}
}
}
output of this is the exactly same looking in prn data file. But when I am trying to embed in html, it is looking weird like this:
Help will be appreciated.
Thank you :)

I am simply trying to call my testImage() method in Wavemaker. I imported the .jar file after running the application perfectly in Eclipse. However when I call the same method in the .jar file in Wavemaker it gives my this error:
Error

I will now show you the TestUrl class which I call to invoke my two methods testImage() and getImage():

public class TestUrl {

// String urlString = "http://www.eurobiopark.org/sites/default/files/EurobioparkMashups5.1.png";
System.out.println("Using " + l);

try {

The Picture is downloaded locally and the Console out is this:

Here is my TestDownload main Class through which I call my two Methods:
package pictures;
import java.io.IOException;
/*
* By: Victor Foning 17/Septembre/2019
*
* From this Main Methods we will call:
*
* TestUrl.java and the GetImage.java Methods

public class TestDownload {
public static void main(String[] args) {
String path = "http://www.eurobiopark.org/sites/default/files/EurobioparkMashups5.1.png";
// We Begin encapsulating the TestUrl Methods
TestUrl im = new TestUrl();
boolean image = im.testImage(path);
if(image){
im.getImage(path);
System.out.print("true");
}
else{
System.out.print(" victor_WakeUP_false");
}
}
}
Here I then export the .jar file (in Bold) into Wavemaker and Make the same method invocation through my JavaService Class:
package com.demo_jquery.myjavaservice1;
import javax.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import pictures.TestUrl;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.HttpURLConnection;

import com.wavemaker.runtime.security.SecurityService;
import com.wavemaker.runtime.service.annotations.ExposeToClient;
import com.wavemaker.runtime.service.annotations.HideFromClient;
Here you will find the class getImageFromWaveMaker()I create inside my javaService1 class to invoke my two methods:
package com.demo_jquery.myjavaservice1;
import javax.servlet.http.HttpServletRequest;

Please help me figure out why I get and Error when I run this code?
Thanks to a bit of meditation and positive re-orientation from some good friends I was able to solve this issue.
I came to realize that even though camelcase is accepted when declaring method. I re-declared both methods in my TestUrl Class by starting them with a Capital Letter.
With reference to the Error Code:
Aslo, understanding that all classes in java are derived from the object class and that the String class is one of the most important class in Java. I made that java.lang.String class the Super Class when I created all my Classes in Eclipse.
I did a maven Compile, which generated a .jar file. I proceeded to upload the .jar file in my resource lib file on Wavemaker, Binded my variables accordingly with my JavaService class and the results were good.
Please feel free to express any further perspective on this issue, I would be glad to hear it. Thank you!
