web.xml

问题 I recently switched one of my static html files to a Spring controller that uses a JSP to render its view. I use jetty to test locally and local testing shows the page rendering fine. Upon deploying to our test server, which uses Tomcat 6.0.26, I get the following exception: javax.servlet.ServletException: Could not get RequestDispatcher for [/WEB-INF/jsp/index.jsp]: check that this file exists within your WAR org.springframework.web.servlet.view.InternalResourceView.renderMergedOutputModel

问题 I have a webapp which has angularJS on the frontend and Java on the backed. Angular communicates with the java backend via Restful webservices consuming and sending JSON across HTTP. I need to build the authentication mechanism for this app and was wondering how would be the best approach, currently I'm using JAAS based authentication (JDBC user table). This is how my app is configured: My web.xml configuration has: <login-config> <auth-method>FORM</auth-method> <realm-name>userauth</realm

问题 Basically I want one servlet to handle all incoming request regardless of the path. I'm on shared hosting environment with access to configure my own web.xml file. I have the following configured in web.xml, but it doesn't work on Tomcat 5: <?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation= "http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee

问题 ( SOLUTION posted at the end of the Question) I am building a Spring 4 MVC app. And it is completely configured using Java Annotations. There is no web.xml .

问题 I've got a regular java file that I use to update and query a mysql database but I need to take configurable options in that file (like host name, password, etc) and put it in the web.xml file (or perhaps another file if that's an option, but ideally in web.xml). But I don't know how to get access to web.xml values from a regular non-servlet java file. Or would I need to read the xml (like any other xml file... or is there a shortcut route to this...) 回答1: You need to put the required

问题 I would like to control the settings in web.xml and using different once for different environments. Is it possible to use a property, from a property file on classpath, in web.xml? Something like this: <context-param> <param-name>myparam</param-name> <param-value>classpath:mypropertyfile.properties['myproperty']</param-value> </context-param> Best regards P 回答1: No. However you can pass the properties file in and read from it at runtime. <context-param> <param-name>propfile</param-name>

问题 I'm bootifying an existing Spring Web application so the generated war file embed a Jetty web server. I want to stick to the existing configuration as much as I can in order to limit the regressions. Here is the existing web.xml : <web-app id="fbecart-webapp" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <context-param> <param-name
