web.xml: Standard deployment descriptor defined by Java EE (Servlet JSR in particular, but used by many JSRs). It is used to specify the metadata used by the web container to deploy the application in a portable manner across application servers (such as the URL endpoint of a servlet). In Java EE 6 and beyond, it … Read more
You can use Ant-style variable substitution in any of the tomcat xml config files, such as: <servlet-mapping> <servlet-name>mvc-dispatcher</servlet-name> <url-pattern>${foo}</url-pattern> </servlet-mapping> Where foo is a Java System Property (sysprop). You can’t use OS Environment Variables (envvars) directly, I think… To use envvars, you can put set “CATALINA_OPTS=-DsomeJavaSysProp=%SOME_OS_ENVVAR%” in bin/setenv.bat (or similarly in bin/setenv.sh for *nix). You … Read more
The error message tells you in detail in what order the elements are supposed to be placed and how many of them are allowed. In other words, the ordering or amount of the elements inside the <web-app> of your web.xml is incorrect. For example, as per the error message, <servlet> needs to go before <servlet-mapping>. … Read more
Do not use classpath. This may cause problems with different ClassLoaders (container vs. application). WEB-INF is always the better choice. <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-config.xml</param-value> </context-param> and <bean id=”placeholderConfig” class=”org.springframework.beans.factory.config.PropertyPlaceholderConfigurer”> <property name=”location”> <value>/WEB-INF/social.properties</value> </property> </bean>
It’s not supported by Servlet API to have the URL pattern wildcard * in middle of the mapping. It only allows the wildcard * in the end of the mapping like so /prefix/* or in the start of the mapping like so *.suffix. With the standard allowed URL pattern syntax your best bet is to … Read more
You need to put the JSP file in /index.jsp instead of in /WEB-INF/jsp/index.jsp. This way the whole servlet is superflous by the way. WebContent |– META-INF |– WEB-INF | `– web.xml `– index.jsp If you’re absolutely positive that you need to invoke a servlet this strange way, then you should map it on an URL … Read more
I guess it has more to do with the servlet spec the container/netbeans is using rather than being an issue with the container. Your net beans seems to be using the spec 2.5 to construct the servlet mapping and hence you get <servlet-mapping> <servlet-name>fred</servlet-name> <url-pattern>*.jsp</url-pattern> <url-pattern>/url</url-pattern> </servlet-mapping> Read more about this here. It says Previous … Read more
Ironically, I was looking for the syntax of how to write this property in tomcat’s web.xml and this is the first search item I opened from google – it’s written correctly too (it works), so thanks. To answer your question though, this allows the servlet to store incoming requests for later response. It frees up … Read more
One very simple solution which solves my problem. Change the schema reference from <!DOCTYPE web-app PUBLIC “-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN” “http://java.sun.com/dtd/web-app_2_3.dtd” > <web-app></web-app> to this <?xml version=”1.0″ encoding=”UTF-8″?> <web-app xmlns=”http://java.sun.com/xml/ns/javaee” version=”2.5″ xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation=”http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd”> // … // your all content goes here </web-app>
<url-pattern>*NEXTEVENT*</url-pattern> The URL pattern is not valid. It can either end in an asterisk or start with one (to denote a file extension mapping). The url-pattern specification: A string beginning with a ‘/’ character and ending with a ‘/*’ suffix is used for path mapping. A string beginning with a ‘*.’ prefix is used as … Read more
