I am developing JAVA web project by using netbeans IDE, I want to display some images from a folder outside the project's directory, after uploading them by my servlets, here is my code:

img in the jsp:
<img src="C:/Users/mohammad/Documents/NetBeansProjects/uploads/name.jpg"/>
servlet:
I am sending it inside a json object:
object.add("<img src=\""+getServletContext().getInitParameter("uploads")+"/"+book.getImage()+"\"/>");
I am sure that the image is exist in that folder, but it couldn't loaded, what is the problem here?
You should add filter on web.XML file of image extensions that actually specify that what kind of external resources can be passed through front controller.. Will u please post your web.xml
U may try this link Upload an image to a Path set in web.xml using primefaces

I understand that there are a lot of similar questions, but i can't find where is my problem. So, my question is: When I had all my code in src package of my project and when I started my tomcat app all was good, but when I rewrote my app to multi module architecture I got error. Maybe I should change some paths or so on? In root target web.xml it gives me:
my web.xml: https://i.stack.imgur.com/K8wRE.png
this is error screen: https://i.stack.imgur.com/7j1Ac.png
my target/web.xml: https://i.stack.imgur.com/Oknrq.png
Building with mvn clean package is ok.

Thanks for attention.
So, my solution was to change artifact. When I change the location of my tomcat webserver, I should change artifact
The Maven dependencies of IntelliJ are not up to date, see the "m"-button. This might be the cause of the problem.
Click on the "m"-button with "turning arrows" in the top right corner of your editor window.
mvn and IntelliJ manage dependencies independently.
I have 3 servlets in my web application.
The first servlet is workinh OK.
The second and third servlet which is copying from the first one, doesn't work and doesn't get response.
However, I search on internet and all websites say: the error in web.xml file
This is my web.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1">

You should put full class names in the <servlet-class> tag.
Also, <web-app> tag is missing some attributes about XML Schema. You can find more information here.
For version 3.1 it should look like this:
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
// your mappings
</web-app>
Closing </web-app> tag is also missing.
I create a web application in Netbeans, named test9. I have create various jsp files and servlets,etc in it.Now i want to change the starting page index.html to index.jsp so I created a new file index.jsp and deleted index.html but after running it, It is still trying to open index.html and displaying 404 error resource not found i even made changes in my xml file but still it is doing it.

In netBeans you can right click button on your project, then properties. A new pop up window will open, and on the left menu there will be a label call run. Click there and then in the "relative URL" you should put
/nameOfYourJspFile.jsp
and it works but i still do not know why
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
did not work.
I know that this is an old post but since i had the same issue and solved it i am posting my answer to help some others who might stuck in a situation like this.
What worked for me was to take the new jsp file out of the WEB-INF folder.
I have tried to find a solution searching on Google, but did not succeed.
This is the structure of my application's folder.
<PROJECT_NAME>
--->WebContent
--->index.html
--->WEB-INF
--->META-INF
I deployed my application in Tomcat server.
My web.xml config file is the following:
<?xml version="1.0" encoding="UTF-8"?>

I try to access localhost:8080/project_name/,and everything works fine, but when I try to access the index.html file like this localhost:8080/project_name/index.html, it doesn't show the index.html content. It shows my root project content. (localhost:8080/project_name/)
How can I get the index file content posted in the browser?
Any help will be very appreciated.
Please note that the folder is named "WEB-INF", not "WEB.INF".
You can use default servlet to serve your static resources. Here is how this can be used with tomcat:
<servlet>
<servlet-name>default</servlet-name>
<servlet-class>
org.apache.catalina.servlets.DefaultServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.html</url-pattern>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
i am trying to deploy my app to GAE but i allways get 404 not found error on all pages(jsp) except for default. RESTful webservices working without problem. I am using netbeans 7.1.1 and gae 1.6.4.1
When I test it locally, everything works fine without any problem. But when I upload it do gae, allways only default page is available. I tryied almost everything.
I tryied to check whether the files are on GAE using appcfg.cmd. I downloaded my files from GAE and found out that noone is missing so the update process was probably successful.
I tryied to upload it with appcfg script instead of netbeans plugin but the process failed because of:
com.google.appengine.tools.admin.JspCompilationException: Failed to compile jsp files.
I cant simply make it working using appcfg script, searech internet for almost whole day and found no possible solution. Uploading with netbeans plugin worked without problem.
So what can be the reason to allways throw 404 on gae? Please help.
Thx very much. If you need any other info, i will be glad to post it here.

After hours of debugging and searching, i found out, that if you want to map jsp files
you have to use
<servlet>
<servlet-name>editPlan</servlet-name>
<jsp-file>**/**xxx.jsp</jsp-file>
</servlet>
instead of
<servlet>
<servlet-name>editPlan</servlet-name>
<jsp-file>xxx.jsp</jsp-file>
</servlet>
The '/' in path is essential, it will work on loaclhost but not deployed on gae. What a crap...
I never mapped JSPs to anything in web.xml. Why do you do that?
