Hello

via eclipse

BTW, I used to do exactly what you are asking for with an Ant script (at least for adding a JAR) - the <copy> task would copy only the new JARs and leave the rest there. But for Maven I always clean and rebuild.

heh, but I thought that eclipse has more tight connection between eclipse and maven, i.e. eclipse is deploying webapp, it knows that all dependencies goes to WEB-INF/lib, it asks maven "give me dependencies"; something like that.

Yes

for instance I have added one dependency, I want it to appear in WEB-INF/lib without repackaging. I want just this one dependency to be copied to WEB-INF/lib. The same with deleting, if I have deleted one dependency I do not want to clean and then package project again, I want this deleted assembly to disappear from WEB-INF/lib.

It is a bit cumbersome to repackage project (not all projects, just only one) when only one file needs to be copied.

Hello

I am using Maven2, Eclipse with m2e plugin and Tomcat. How can I configure eclipse to take maven dependencies when deploying to tomcat? I have configured (in project properties) deployment assembly which folders to take for deployment, but when I have to change list of dependencies I have to clean and then package all project again, that is a bit long process. How can I tell eclipse that it has to take all necessary dependencies, so cleaning and subsequent packaging won't be necessary.

Hello

I am stuck with some weird xml validation error. Eclipse says
-Cannot resolve the name 'j2ee:descriptionGroup' to a(n) 'group' component.

<?xml version="1.0" encoding="UTF-8"?><!--eclipse underlines this line as errorneous--> <web-app 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">

but despite this fact webapp is successfully compiled and deployed

could you explain me, what is root of this error and how to avoid it?

I have already done it.
I have used reCaptcha, no problems here. Main problem was to intercept authentication process to check captcha and reject authentication whenever that is necessary. I don't know if my way is the best one, so if there is better solution I would like to hear it . I had to declare my own authentication provider sublassed from DaoAuthenticationProvider and there I overrode additionalAuthenticationChecks, that is a place where I verify captcha. Moreover I subclassed WebAuthenticationDetails to save captcha from request for subsequent verification. That was a bit difficult to tie together, as I am new to spring and had to search internet for lots of things.

I think books is more user friendly than just a documentation

how one can measure amount of knowledge you get?

Hello

I would like to add captcha to a login form, how can I implement it?

you could try start reading their documentation to get used to their inversion of control container first

Hello, I have recently encountered the same problem

matter is not in model, If you bind correctly, object is contained in it, you have to specify correct xml schema

I am trying to get spring security working, but still no luck

I have web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" 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_3_0.xsd" version="3.0"> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/applicationContext-security.xml </param-value> </context-param> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> </welcome-file-list> </web-app>

and applicationContext-security.xml
<?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> <http auto-config="true"> <intercept-url pattern="/register.html" access="IS_AUTHENTICATED_ANONYMOUSLY" /> <intercept-url pattern="/*" access="ROLE_USER, ROLE_ADMIN" /> <logout logout-url="/logout"/> </http> <beans:bean id="myUserDetailsService" class="labas.spring.service.UserDetailsImp"/> <authentication-manager> <authentication-provider user-service-ref='myUserDetailsService'/> </authentication-manager> </beans:beans>

when I run it, I get
java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered? org.springframework.web.filter.DelegatingFilterProxy.doFilter(DelegatingFilterProxy.java:159)

thank you, proper xmlns helped

this variable goes from spring model, which scope is it in jsp page?

actually isELIgnored="false" helped, but how can configure application to avoid including this attribute

Hello

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <html> <body> <c:out value="${cmd}" ></c:out> <a href="contacts.html">back</a> </body> </html>

after execution I get in output ${cmd} but not its contents, how to solve this?
