I wanted to create log.html file using java wherein i'll dump errors into html table-row as and when errors are caught. I created table columns but when i am passing anything to it then my data is overwriting column names instead of appending row. My java code is as follows:
public static void main(String[] args) throws IOException
{
String month = getMonth(1);
System.out.println(month);
//table(month);
addrow("abc");
}
public static void table(String Update) throws IOException
{
//define a HTML String Builder
StringBuilder htmlStringBuilder=new StringBuilder();
htmlStringBuilder.append("<html><head><title>Packaging Issues</title></head>");
htmlStringBuilder.append("<body><h1> Files Received </h1>");
htmlStringBuilder.append("<table border=\"1\" bordercolor=\"#000000\">");
htmlStringBuilder.append("<tr><td><b>Cycle</b></td><td>"+Update+"</td></tr>");
htmlStringBuilder.append("<tr><td><b>Version</b></td><td></tr>");
newtable(htmlStringBuilder.toString());
}
public static void newtable(String a)
{
StringBuilder htmlStringBuilder=new StringBuilder();
htmlStringBuilder.append(a);
htmlStringBuilder.append("<h1> Issues Found </h1>");
htmlStringBuilder.append("<table border=\"1\" bordercolor=\"#000000\">");
htmlStringBuilder.append("<tr><td><b>Type</b></td>");
htmlStringBuilder.append("<td><b>Field</b></td>");
htmlStringBuilder.append("<td><b>Issue</b></td></tr>");
addrow(htmlStringBuilder.toString());
// WriteToFile(htmlStringBuilder.toString(),"log.html");
}
public static void addrow(String a)
{
try {
StringBuilder htmlStringBuilder=new StringBuilder();
htmlStringBuilder.append("<tr><td><b>"+a+"</b></td>");
htmlStringBuilder.append("<td><b>Field</b></td>");
htmlStringBuilder.append("<td><b>Issue</b></td></tr>");
htmlStringBuilder.append("</table></body></html>");
WriteToFile(htmlStringBuilder.toString(),"log.html");
} catch (IOException e) {
e.printStackTrace();
}
}
Here's the writetofile method:
public static void WriteToFile(String fileContent, String fileName) throws IOException {
String projectPath = "/home/abc";
String tempFile = projectPath + File.separator+fileName;
File file = new File(tempFile);
// if file does exists, then delete and create a new file
//write to file with OutputStreamWriter
OutputStream outputStream = new FileOutputStream(file.getAbsoluteFile());
Writer writer=new OutputStreamWriter(outputStream);
writer.write(fileContent);
writer.close();
}

The constructor FileOutputStream(file) overwrites the contents of the file. Use this constructor instead
FileOutputStream fos =new FileOutputStream(file, true) ;
