I'm completely at a loss as to why this is occurring. I have a javascript file deployed to three test boxes. On two of them, I get the following error when I hit the page (below). As you can see, it says the stream header is a string of zeroes, and there are no zeroes in the file it's reading. I assume this means that it's trying to read the data but nothing's coming through (hence all the unset bits...) but the fact that it works on one box but not the other two is baffling, since they all have the same code deployed to them.
I've looked through the Java service for any streams that aren't closed or read properly, but the service doesn't even open them. As you can see in the stack trace, it utilizes Ehcache which performs those operations (and are implemented correctly).
Any pointers in the right direction on what in the world this is doing?

Above This is my HTML Code which I am getting error code
Mon Jan 04 00:24:01 EST 2021
There was an unexpected error (type=Internal Server Error, status=500).
An error happened during template parsing (template: "class path resource [templates/hello.html]" - line 4, col 7)
org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/hello.html]" - line 4, col 7)
at org.thymeleaf.templateparser.markup.AbstractMarkupTemplateParser.parse(AbstractMarkupTemplateParser.java:239)``
These are the solutions I have tried.
I did not bother putting the un-important parts which are the first 3 line that are giving me errors.
I added
xmlns:th="http://thymeleaf.org"
and even
xmlns:th="https://www.thymeleaf.org"
as well as
xmlns:th="http://www.thymeleaf.org"
none of the three above have worked
I have have changed my controller around a bit on the java side which looks the code below
#Controller
public class WebController {
#GetMapping("/hello")
public String sayHello(HttpServletRequest request){
System.out.println("Saying hello world Spring Boot....");
request.setAttribute("message", "Greetings");
return "hello";
}
}
This error is unclear to me, I believed it was something on my end but, sometimes it is possible that you must start the project from scratch in order to get things working again.
Your code is running fine in my machine. You forgot to add www in
xmlns:th="http://thymeleaf.org"
So that you should add this
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
I have read all of the Java URL encoding threads on here but still haven't found a solution to my problem: Google Chrome encodes "BŒUF" to "B%8CUF" POST data, awesome. How can I convince Java to do the same? (The website is <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="fr"> and <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> in case this is important.)
System.out.println(URLEncoder.encode("BŒUF", "utf-8"));
System.out.println(URLEncoder.encode("BŒUF", "iso-8859-1"));
System.out.println(URLEncoder.encode("BŒUF", "iso-8859-15"));
System.out.println(new URI("http","www.google.com","/ig/api","BŒUF", null).toASCIIString());
prints
B%C5%92UF
B%3FUF
B%BCUF
http://www.google.com/ig/api?B%C5%92UF
but not "B%8CUF"?
You are specifically looking for windows-1252 encoding not UTF-8:
System.out.println(URLEncoder.encode("BŒUF", "windows-1252"));
Gives,
B%8CUF
PDFTextStripper stripper = new PDFText2HTML(encoding);
String result = stripper.getText(document).trim();

Short of OCR'ing it you don't.
The PDF in question does not contain the information required to extract text without doing at least some OCR (at least OCR'ing each character of the used font to find a mapping from glyph to character) which would require additional libraries and code.
As a requirement for text extraction the PDF specification ISO 32000-1:2008 correctly states in section 9.10.2 that the font used for the text to extract needs to
either contain a ToUnicode CMap — the font used in your document doesn't —
or be a composite font that uses one of the predefined CMaps listed in Table 118 (except Identity–H and Identity–V) or whose descendant CIDFont uses the Adobe-GB1, Adobe-CNS1, Adobe-Japan1, or Adobe-Korea1 character collection — the font used in your document isn't —
or be a simple font that uses one of the predefined encodings MacRomanEncoding,
MacExpertEncoding, or WinAnsiEncoding, or that has an encoding whose Differences array includes only character names taken from the Adobe standard Latin character set and the set of named characters in the Symbol font — the font used in your document neither uses one of those predefined encodings nor are the character names in its Differences array from those selections mentioned: the names used are /0, /1, ..., /155.
Generally a good first test is to try and copy&paste text using Adobe Reader as much text extraction experience is in the Reader's code. When trying to do so, you'll see that you only get garbage.
I develop a facebook application using flex' s XMLSocket and Java.
When i type 'ş' character in my client side, it prints, however when i send 'ş' character,
it is printed as ??? or any kind of unpredictable characters.
I tried to change my html file's meta tag to
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
but it did not work.
On the whole how can i get rid of this problem.
Thanks.
Use encodeURIComponent(yourstring), this might do the trick.
I am facing an error after moved my site from one server to other.
My problem is java bean is working fine if page is at root folder. for example "mydomain.com/page1.jsp" is working fine BUT if I put the page in folder then it's give me below error. for example "mydomain.com/test/page1.jsp" is give me error.

JSP code is :
<%#page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*,java.lang.*" import="java.text.*" import="java.util.*" errorPage="" %>

Can anyone guide me what can be the problem. OR do I need to take care anything specially when I change my server? Earlier and now, both time there is linux server Apache tomcat 5.5.
Where is WebdbBean class? The WebdbBean.class must be at WEB-INF/classes/com/realtor/website
This error basically means that the following
WebdbBean webdb = new WebdbBean();
has failed. Given the fact that it works fine in another page (and that you didn't typo'ed the class attribute), it's definitely in the classpath, so a possible cause of ClassNotFoundException can be scratched. Left behind that the bean's construction has plain failed. Apparently you're doing something in the default constructor which can possibly throw an unhandled exception. Its stacktrace should then be visible in the server logs. Read it and fix the root cause accordingly.
