JSP Tomcat7 static css and js files not loading - java

Learning JSP and have an issue with the css/js content not loading. I have a jsp page, where I have bootstrap css and js referenced using standard html link and script tags:
<link rel="stylesheet" type="text/css" link="/bootstrap/css/bootstrap.css" />
and
<script src="/WebIntro/bootstrap/js/bootstrap.js"></script>
neither of them work and Chrome is giving me the following on the console:
Resource interpreted as Stylesheet but transferred with MIME type text/plain:
If I use an include directive, it works for the css but pulls all the content into the file:
<%#include file="/bootstrap/css/bootstrap.css"%>
The jsp has the following #page and meta tags:
<%#page contentType="text/html" %>
and
<meta http-equiv = "Content-Language" content = "en"/>
<meta http-equiv = "Content-Type" content="text/html; charset=utf-8">
I tried googling and found the mime-mapping element for the web.xml but the following seems to have no affect:
<mime-mapping>
<extension>css</extension>
<mime-type>text/css</mime-type>
</mime-mapping>
<mime-mapping>
<extension>js</extension>
<mime-type>application/javascript</mime-type>
</mime-mapping>
If there is some standard Tomcat config that needs to happen I am unaware as I am new to Tomcat; using Tomcat 7, and eclipse and this is in a maven project.

The solution for me was very strange. The changes to the web.xml file that was present since I built the project in eclipse/maven, weren't reflected in the web.xml within tomcat webapp application directories. Everything else in the package updates fine (as far as I can tell), except for the web.xml?
So I found the web.xml file within eclipse inside target >> project-SNAPSHOT >> WEB-INF >> web.xml (which is supposed to be derived). Forced changes there and it worked, changes were picked up and my original issue gone.
I am guessing I had inadvertently broken some type of dependency link or something along the way somehow, but once I added the servlet, mappings, etc back in, everything worked fine.
Weird.

Removing this line in jsp resolved the error for us.
We were facing the issue when using Tomcat 8.5.59

Tomcat 9 Failed to load resource: the server responded with a status of 404 ()

I've encoutered some problems with using tomcat.For some reason tomcat can't load my stylesheet.The link is defined inside the head.jsp,this file i include using the include directive in all my jsps that need the stylesheet.I found out that this problem occurs when i dispatch from Servlet to Jsp using the request.getRequestDispatcher(...).When i accessed the same file directly,the stylesheet loads normally.

You are missing context path of project.
Case 1: Consider your current URL is http://localhost:8585/project_name/
Then including stylesheet with` ``href = "css/style.css"```
==> http://localhost:8585/project_name/css/style.css
Case 2: Consider your current URL is http://localhost:8585/project_name/users
Then including stylesheet with` ``href = "css/style.css"```
==> http://localhost:8585/project_name/users/css/style.css
404 error
So use context path as prefix, To use context path while including javascript or stylesheet use JSTL tag library and url tag to achieve it as given below.
Include JSTL
<%#taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
Include stylesheet or scripts by using jstl url tag as given below
<link rel="stylesheet" href="/css/style.css" />" >

CSS not loading in spring boot application

I have been searching all day, moved the style.css everywhere and still not managed to get it loaded. The images wont load as well.
My structure:
But if i click the firefox button, it loads:
This is how the style.css is imported in the head of the index:
(tried all kind of combinations)
When i check the developer tools, it says 404 for GET request (style.css and the pictures)
Spring Boot knows where the static directory is, so you don't need to use the ../ technique to get to the files within. The other part is that you should be using an annotation to get there. It may depend on what view template you are using, but for thymeleaf this is how you would achieve pulling in the css file:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<head>
<title>Your Title</title>
<link rel="stylesheet" th:href="#{/css/style.css}" />
</head>
Notice the annotation in th:href="#{/css/style.css}"
Make sure you include the namespace of your view template, th in the example.
Images work the same way:
<img th:src="#{/img/stanev2.png}" />

JSP cannot find default bundle for i18n

After browsing through the whole internet I ended up asking this question, although I find it a bit difficult to describe the situation.
I have a little application here which runs on embedded Tomcat server (v7), and uses servlets and JSPs; I try to internationalize them with JSTL tags. The final project is deployed as JAR, and when I run it from the console with java -jar, the embedded server starts nicely, everything works just fine.
The problem is when I try to run it in the IDE (I use IntelliJ Idea v13.1.2): again, it starts, but instead of the values from the bundle, the pages show values such as ???default.username???.
Here is how my JSPs mostly look like:
<!DOCTYPE html>
<%# taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%# page contentType="text/html;charset=UTF-8" %>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:set var="language"
value="${not empty param.language ? param.language : not empty language ? language : pageContext.request.locale}"
scope="session"/>
<fmt:setLocale value="${language}"/>
<fmt:setBundle basename="messages" scope="session" var="bund"/>
<html>
<head>
<title><fmt:message bundle="${bund}" key="default.title" /></title>
<link rel="stylesheet" type="text/css" href="../css/tdb.css" media="all">
</head>
And so on. The <fmt:message bundle="${bund}" key="default.title" /> and similar parts work perfectly fine when I use the JAR, and result in ???default.title??? when from IDE. In one case I use the bundle file from the servlet, and when ran from JAR, it works fine, and when from IDE, it causes java.util.MissingResourceException.
What have I tried so far? I added my messages.properties and messages_en_US.properties files in various locations (in resources folder, on the same level with the java and webapp folders; in separate package in the com.my.example package; as simple properties files in the com.my.example package), tried to refer to it only with the basename (resourceBundle = ResourceBundle.getBundle("messages", locale);), or with the fully qualified path; also, I set the fallbackLocale and localizationContext parameters in the web.xml file.
What am I missing?
Code looks well.
I was checking in some of my projects and I have this attributes:
<fmt:setBundle basename="org.juanitodread.msg.label" var="label"/>
<fmt:message key="common.title" bundle="${label}" />
I have my projects in Eclipse, but you can try without "scope" attribute. My label.properties file is in "org.juanitodread.msg" package.
I also use the Intellij Idea and had the similar problems, here are my conclusions. You should put your 'messages file' to
yourproject/src/main/java/resources
folder (as a rule, Idea will highlight the resources folder icon with the specified sign). I have no fallback locale configuration and localization context parameters in web.xml. My bundle file is named messages_en.properties and I use it the way
<fmt:setBundle basename="messages" var="labels" />
and not add "resources.messages" to basename attribute.
I'm running IntellijIdea version 2016.2, and my application works fine on:
embedded Tomcat v 7.0.73 , using bmuschko gradle-tomcat plugin https://github.com/bmuschko/gradle-tomcat-plugin
remote Tomcat v 7.0.73 deployment with Tomcat Server Idea configuration
To check your resources are really loading (if your properties are not loaded to the page that means you're obviously missing the file), use the following code, as mentioned in https://stackoverflow.com/a/4137991/2759640
ClassLoader ctxLoader = Thread.currentThread().getContextClassLoader();
URL propsURL = ctxLoader.getResource("opto-mapping.properties");
URLConnection propsConn = propsURL.openConnection();
In case you have your resources loaded, openConnecton will throw an exception, that connection to the messages.properties has been already opened (at least I've done that way and tried to make my bundle work also for a long time).

HTML embed not working for Java Applet

I've been researching on which to use between <applet>,<object>, or <embed>, but none seem to work.
When I tried to load JApplet through HTML I am got RuntimeException error java.lang.NoClassDefFoundError: com/sforce/ws/ConnectionException.
When I tried to run number1.class with the number1.class being in myfile.jar it needs the other 3 jar files for the library and that is what the error is. The files look like this:
tomcat-->webapps-->applet-->newhtml.html
applet-->lib-->(wsc-23,enterprise,partner)
applet-->applet_class-->(number1.class,myfile.jar)
Any help would be appreciated.
I've also looked through majority of stackoverflow questions as well as other places, but still no luck!
<!DOCTYPE html>
<html>
<body>
<html type="application/x-java-applet;version=1.6"
width="512" height="512"
code="applet_class.number1.class"
src="myfile.jar,applet/lib/wsc-23.jar,
applet/lib/enterprise.jar,
applet/lib/partner.jar"/></html>
</body>
</html>
The best way to deploy a JWS app. or applet is to use the Deployment Toolkit Script.
But looking at that element..
<html type="application/x-java-applet;version=1.6"
width="512" height="512"
code="applet_class.number1.class"
src="myfile.jar,applet/lib/wsc-23.jar,
applet/lib/enterprise.jar,
applet/lib/partner.jar"/></html>
The most basic form of the applet element (deprecated in HTML 4.01 is):
<applet
width="512" height="512"
code="applet_class.number1"
archive="myfile.jar,applet/lib/wsc-23.jar,applet/lib/enterprise.jar,applet/lib/partner.jar"/>
</applet>
Change html to applet.
Remove the type attribute.
Remove the .class from the end of the code attribute.
Change src to archive, and have all the archives in one line.

Error when including jsp files on my jsp page

I am trying to include 2 JSP files in my JSP page. My main page is called temp.jsp - this is in a subfolder in my web project called tempFolder.
I am trying to include a file in the main project folder (called invalidcqs.jsp) and a file (called env_status_report.jsp) in a sub folder (envmon) of the main project folder.
the code in my temp.jsp file is:
<html>
<head>
<title>Screen1 using includes</title>
<meta http-equiv="refresh" content="10"/>
</head>
<body style="background-color:#E6E6FA">
<%# include file="../envmon/env_status_report.jsp" %>
<br><hr><br>
<%# include file="../invalidcqs.jsp" %>
</body>
</html
The second include <%# include file="../invalidcqs.jsp" %> works fine but the first one <%# include file="/../envmon/env_status_report.jsp" %> shows an error in Eclipse.
The text of the error is:
Multiple annotations found at this line:
- Syntax error on token "else", delete this token
- Syntax error, insert "Finally" to complete
TryStatement
- Syntax error on token "else", delete this token
Does anyone know why Eclipse doesn't like this?
Usually I don't care much about Eclipse reporting errors on jsp pages, specially when using the <%# include> directive. For instance, if you declare a scriptlet variable in your main page and use it in the included page, Eclipse will complain about it not being declared while in the included page, but it will work all right at runtime.
This error is possibly coming out of the included jsp, so I'd start looking for this error inside it.
You could also try to include pages the EL way:
<jsp:include page="/WEB-INF/pages/received.shtml" />
Maybe that will help
