Unable to locate Spring NamespaceHandler for XML schema namespace

[Suhas Bilaye]

Hi all,

I am trying to integrate spring security within my GWT application. But when I run the application in hosted mode, I am getting the following exception

  com.google.gwt.dev.shell.jetty.JettyLauncher$WebAppContextWithReload@1b44184{/,E:\bakupD\MerlinVersion2\GWTApplication\war}
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem:

web.xml

	</filter>
	<filter-mapping>

	</filter-mapping>    

Kindly Help

Hi,

The issue is resolved. I had to copy the "spring-security-core-tiger-2.0.5.RELEASE" jar also in the WEB-INF/lib folder along with the "spring-security-core-2.0.5.RELEASE" jar.

Regards,
