问题 Under JBoss 5.1 we used to "stage" values in the web.xml and the jboss-web.xml by using SystemProperties. In the web.xml that looked like this: <web-app [...]> [...] <auth-constraint> <role-name>${myRole}</role-name> </auth-constraint> [...] <login-config> <auth-method>${myAuthMethod}</auth-method> </login-config> <security-role> <role-name>${myRole}</role-name> </security-role> </web-app> Additionally we did the same thing for the jboss-web.xml and the security-domain.

问题 I have read most of the similar issues that already posted but still I couldn't find a solution. Please note that regular CRUD application is working fine. I'm getting this error when I try to add login functionality via spring-security. My working environment is as follows; 1.Tomcat 7.0.35 2.Spring 3.2.0 3.Spring security spring-security-config-3.1.3.RELEASE.jar spring-security-core-3.1.3.RELEASE.jar spring-security-taglibs-3.1.3.RELEASE.jar spring-security-web-3.1.3.RELEASE.jar 4.My web.xml

问题 I need to define many servlets, but I don't want to write the configuration all in the web.xml. Can I define some servlet configuration files, and include them in web.xml? Or is there any other way to split a web.xml to multi files? 回答1: The Servlet 3.0 specification provides a new annotation, @WebServlet , that may be used to declare servlets in the code without the need for the web.xml. See Section 8.1.1 of the Servlet 3.0 specification and review the javadoc for more details. @WebServlet("

问题 How does a look-up like : Context envContext = (Context)initContext.lookup("java:comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/MyDatasource"); proceed ? I mean to say how is the name MyDataSource searched and in the end what is returned ? There are two entries added to connect to the database. One in the WEB-INF/web.xml which is : <resource-ref> <description>my connection</description> <res-ref-name>jdbc/MyDatasource</res-ref-name> <res-type>javax.sql.DataSource</res-type>

问题 I have a servlet filter which I want to map to http://127.0.0.1:8888/ in Jetty. I have put a servlet filter mapping with url pattern /* . However, the filter is not called. I also tried with / mapping. It does not work either. How is this caused and how can I solve it? 回答1: If you name your war root.war it will be deployed to the root / context. http://wiki.eclipse.org/Jetty/Howto/Deploy_Web_Applications 回答2: You can redirect requests from "/" to "/urlToRedirect" and handle "/urlToRedirect"

问题 This is my first web application, I am just trying to follow guides and launch my server with servlets specified at web.xml , but it seems that my actions don't change functionality of the server and the result is 404 error. But if I programmatically specify servlets its OK. Could anyone figure it out how this all should work? Here is my code for server public class Launcher { public static void main(String[] args) throws Exception { Server server = new Server(8080); WebAppContext web = new

问题 So I used to configure my taglib like that: <jsp-config> <taglib> <taglib-uri>myTags</taglib-uri> <taglib-location>/WEB-INF/lib/mylib-2.0.1.jar</taglib-location> </taglib> </jsp-config> But now mylib-2.0.1.jar is a maven dependency, so of course it is NOT on /WEB-INF/lib. How do I do to configure my taglib so I can do that in my JSPs: <%@ taglib uri="myTags" prefix="mt" %> EDIT1: To clafiry, the taglib.tld is inside the META-INF inside the jar so you can access the tld by referencing the jar

问题 I want to provide a custom 404 error page in my Spring 3.1 web application, but I cannot deactivate Jetty 8's default 404 error page. Jetty 8, out of the box, provides a default 404 error page: when visiting a Jetty-hosted website, and providing a URL path that is not handled by any servlet (e.g. by visiting http://www.example.com/nonexisting ), Jetty responses with its own default HTML error page : HTTP ERROR 404 Problem accessing /nonexisting.
