It sounds like you are using the wrong url. Tomcat generally has a folder called webapps for applications that are deployed on that server. To figure out the configuration, in Eclipse, open up the Server tab, find your Tomcat server and double-click on it.
It should bring up a properties pane with two tabs at the bottom Overview and Modules. Click on Modules and you should see the path to your app. For me, it's in the form of: /webapps/<project name>
Your full url would be localhost:8080/webapps/<project name>/anystringhere.do since you map anything in your app (localhost:8080/webapps/<project name>/) that ends in .do to the action servlet.

I am new to Spring MVC framework and I was just trying to follow the steps in this example "https://www.tutorialspoint.com/spring/spring_mvc_hello_world_example.htm". However, the page does not show whatever inside ${} and displays an empty page. I tried it with Tomcat v9.0 and Tomcat v6.0, both didn't work. I also tried both dynamic web module 2.4 and 3.1 but didn't work either. I would appreciate any help, I'm sorry if my mistake is simple or apparent.

when i try to upload file to server then no action perform i dint create client direct run it html file in tomcat server and try to access it please help me what we need to do change this i am writing first time so please help .
You didn't put enough stuff in web.xml, so the container does not know how to route request to your Jersey servlet.
Add the following to your web.xml:
<servlet>
<servlet-name>UploadServlet</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>pkg.rest</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>UploadServlet</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
You need to have the pattern /rest/* in all the url's which you want to be handled as a service.
I am having an interesting problem with the PrimeFaces 4.0 final FileUpload element.
I am trying to run:
PrimeFaces 4.0 final
Apache MyFaces 2.2.0-beta
Tomcat 7.0.27
I have a very simple setup right now,
XHTML page:
<?xml version="1.0" encoding="UTF-8"?>

allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />
<p:growl id="messages" showDetail="true" />
</h:form>
</h:body>
</html>
With this backing bean:
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import javax.faces.context.FacesContext;
import org.primefaces.event.FileUploadEvent;
#ManagedBean
#RequestScoped
public class FileUploadController
{
public void handleFileUpload(FileUploadEvent event)
{
FacesMessage msg = new FacesMessage("Succesful", event.getFile()
.getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
}
When selecting a file and uploading it, nothing happens.
The upload submit succeeds with the following response:
<?xml version="1.0" encoding="UTF-8"?><partial-response><changes><update id="j_id__v_0:javax.faces.ViewState:1"><![CDATA[2C7ZmtwSmrlbgI/wJLI2CLBaMOQP9R/pYkIXpHlXkhSKIhtfFM0sx0HmL8o9MQY2MdHXg4t1vUjJbUYkAdFBmOQUaFy7hFhPr34Za4hOuLW4CPNx]]></update></changes></partial-response>
but no message is displayed, and if I set a breakpoint, it does not get hit.
If, however, I pull out MyFaces 2.2.0-beta and put in Mojarra 2.2.0, everything works as expected.
I would prefer to continue to use MyFaces as it is what I've used in the past, so if anyone has any ideas as to a patch to get this to work, it would be much appreciated.
Thank you

Update
It seems that Myfaces 2.2.0-beta has problems using the Part API present in servlet 3.x.
udaykiran pulipati has part of a solution with using web the web.xml filters that PrimeFaces 3.x required and the commons file upload & commons io jars, however, we also need to add the following context-param to the web.xml or the filters get ignored :
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>commons</param-value>
</context-param>
This will force PrimeFaces to use the commons library which fixes the problem
That being said, I would still like to know why MyFaces can't seem to use the servlet Part API if anyone has any ideas. I suspect it may have to do with my Tomcat version as I am only on 7.0.27, but I doubt that.
Mention below filters in web.xml file for uploading a file using PrimeFaces
<!-- PrimeFaces FileUpload Filter -->
<filter>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
and add jars to lib folder. PrimeFaces needs below jars for fileuploading.
commons-fileupload-1.3.jar,
commons-io-2.4.jar
Recently it was found a similar issue with a better description in MYFACES-3835. It was a problem related to webkit browsers that only appears when the ajax response is large enough. It has been already fixed.
udaykiran pulipati's answer motivated me to replace commons-fileupload-1.2.2.jar with commons-fileupload-1.3.jar in my project, but that didn't solve the issue for me, as I'm using MyFaces 2.2, PrimeFaces Elite 4.0.8, and TomEE 1.6.1-snapshot.
Also, per udaykiran pulipati's answer, I already added PrimeFaces FileUpload filter config to my web.xml, many months ago.
So, I looked at PrimeFaces 4.0 user guide, and recognized something 'new' that could be specified in web.xml. So, I added the following to my web.xml,
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>commons</param-value>
</context-param>
and finally, PrimeFaces (Elite) 4.0.x FileUpload works with MyFaces 2.2.
I have a question about realm authentication, where glassfish create more than one http session. Here's an example
Web.xml:
<security-constraint>
<web-resource-collection>
<web-resource-name>AllPages</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>user</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>FileRealm</realm-name>
</login-config>
<security-constraint>
glassfish-web.xml:
<security-role-mapping>
<role-name>user</role-name>
<group-name>users</group-name>
</security-role-mapping>
login.jsp:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Welcome Page</title>
</head>
<body>
<p>You have successfully logged into the application.</p>
go to home
</body>
</html>
SessionListener:
#WebListener public class SessionListener implements
HttpSessionListener {
public void sessionCreated(HttpSessionEvent arg0) {
System.out.println("Session created id:"+arg0.getSession().getId());
}
public void sessionDestroyed(HttpSessionEvent arg0) {
System.out.println("Session destroyed id:"+arg0.getSession().getId());
}
}
When I authenticate, glassfish create a new session:
INFO: Session created id:29c5d904db0e40b9cfbdac40aa5e
And when I click on "go to home" link or refresh the page, glassfish create another http session:
INFO: Session created id:2a67270137e38c150bf3690e2e46
And I also noticed that glassfish never destroy the first created session.
Thank's for your help
This is probably a Glassfish Bug.
Try add context.xml to your META-INF directory with this option:
<?xml version='1.0' encoding='utf-8'?>
<Context>
<Valve className="org.apache.catalina.authenticator.BasicAuthenticator"
changeSessionIdOnAuthentication="false" />
</Context>
or (in case web form authentication):
<?xml version='1.0' encoding='utf-8'?>
<Context>
<Valve className="org.apache.catalina.authenticator.FormAuthenticator"
changeSessionIdOnAuthentication="false" />
</Context>
This should (temporary) solve your problem!
Say I have a struts.properties file with a defined value uploads.directory . How can I access that value from an Actioncontext programatically?
You can use getText("some.property.name") which return you the property value
http://struts.apache.org/maven/struts2-core/apidocs/com/opensymphony/xwork2/ActionSupport.html
Create ActionSupport Object and by using getText() method of ActionSupport class.
ActionSupport actionSupport = new ActionSupport();
actionSupport.getText("foo.bar");
Create a resources folder under src.
In the struts.xml file add a constant e.g., <constant name="struts.custom.i18n.resources" value="global"></constant>
Here global is the name of properties file.
Now you will be able to use the properties in the entire application.

global.properties
action.welcome.username=waqar
In action class
System.out.println(getText("action.welcome.username"));
You need to put the my.properties file or my_locale.propeties file in the package that houses your action class.
You need to put the values in properties files other than struts.properties for examples ApplicationResources.properties or my.properties which needs to be in the classpath. struts.properties file is used to load struts specific properties for example struts.i18n.encoding=UTF-8 or struts.devMode = false etc.
The thing you need to do in struts.properties after you create the properties file for your customized messages is you have to add the following property in struts.properties file
struts.custom.i18n.resources=ApplicationResources
If you have more than one custom message property files then you need to add them by separating with comma for example:
struts.custom.i18n.resources=ApplicationResources,my
Then in your action classes you can access the property values by using getText('propertyName')
you can get value from message resource file like this:
public class MyAction extends ActionSupport {
public String getUserDetails() {
if("First Name".equals(getText("label.firstName"))) {
System.out.println("In if block");
}
}
}
you can also get more information, how to get values from .properties files in java class or jsp files.
for JSP:
<s:text name="label.firstName" />
and
<s:property value="getText('label.age')" />
for more information you can go through this link:
