I'm having problems with my chat project, which i'm building for learning purposes. I'm having a weird little problem with PrimeFaces fileUpload component. It is working fine for a file not larger than 30kb (for larger file it throws HTTP error 400).I'm using PrimeFaces 5.3, Apache commons-io 2.3, Commons-fileupload 1.3. Because this is my learning project, i have uploaded it on public git repository, which is, for better understanding of the problem, accessible here: https://bitbucket.org/salkovich123/testfileupload.git
The fileUpload component is located in file register.xhtml.
I am also sharing my web.xml file here:

This are the header details, which throws HTTP error 400 (bad request)
UPDATE #1
This is most definetly some kind of jQuery problem, because error is thrown in browser console, and no other server side methods are called after thrown error

I wonder what is the equivalent of the following code ( web.xml) in Java.
.........................................................................
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>
<!-- Welcome page -->
<welcome-file-list>
<welcome-file>faces/index.xhtml</welcome-file>
</welcome-file-list>
<!-- JSF mapping -->
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Map these files with JSF -->
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
And xml(extensible markup language) file is just a way to store and transport data. There is no equivalent java class nor instance.
To learn more about how this data is used check: java servlets
I've created a simple JAX-RS resource class for my Java EE based project. I am trying to get a response back from the server but when I access my url I get an error back. This is the class that I wrote:
#Path("/rest")
public class RestResource {
#GET
#Produces(MediaType.APPLICATION_JSON)
public String create(String name)
{
return "print my string";
}
}
I cannot figure out what I'm doing wrong.
Do I have to define a new servlet in my web.xml? Is there something wrong with my current one?

I am just a beginner in primefaces and I just want to know how I can remove the uploaded file. Another one is that within <p:fileUpload> tag, can I show the uploaded file for update or remove? Is this supported by <p:fileUpload>? My uploaded file is not yet on the disk or in the database but still is an object. My code is as below. Please help me or give me some idea.
This is fileupload.xhtml
<h:outputLabel value="Choose Image:" />
<p:fileUpload fileUploadListener="#{ManageProductCode.handleFileUpload}" mode= "advanced"
sizeLimit="3000000" allowTypes="/(\.|\/)(gif|jpe?g|png)$/" id="MyAttachment" fileLimit="1"
required="true" requiredMessage="Image Is Require."/>
<br/>
This is my backing bean. That is just assigning value to persist into database.
private UploadedFile uploadFile;
public UploadedFile getUploadFile() {
return uploadFile;
}
public void setUploadFile(UploadedFile uploadFile) {
this.uploadFile = uploadFile;
}
public void handleFileUpload(FileUploadEvent event){
uploadFile = event.getFile();
System.out.println("UploadFileName is" + uploadFile.getFileName());
byte[]image = event.getFile().getContents();
productCode.setImage(image);
}
This is my web.xml

<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>

I'm using Javamelody in my application. I need only root users to access the statistics. Javamelody by default you can access
http://localhost/webapp/monitoring
I need to change it to
http://localhost/webapp/monitor/monitoring
I have done the following filter mapping
<filter>
<filter-name>monitoring</filter-name>
<filter-class>net.bull.javamelody.MonitoringFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>monitoring</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<listener>
<listener-class>net.bull.javamelody.SessionListener</listener-class>
</listener>
<filter>
<filter-name>monitoring</filter-name>
<filter-class>net.bull.javamelody.MonitoringFilter</filter-class>
<init-param>
<param-name>monitoring-path</param-name>
<param-value>/admin/monitoring</param-value>
</init-param>
</filter>
I'm trying to get the items for a selectOneMenu updated after a file has bee uploaded. To do it, I load the select items at the file upload listener and set the id for the selectOneMenu in the update attribute for the fileUpload component, but the file upload listener is not even called.
I've reproduced the error in a small project I uploaded here http://www.filedropper.com/file-upload
I'm working with PrimeFaces 3.5 on a JBoss AS7.1.3
I can't find what I'm missing. Any ideas?
Thanks in advance
This is the resulting web.xml, including the missing faces servlet declaration and mapping that solved my problem.
