GWT 1.6 + Spring Security issue

[tim.clymer]

I've been seeing a strange issue when attempting to use GWT with
Spring Security as described here:
http://code.google.com/p/gwt-incubator-lib/

I can deploy the application as a war and run it just fine in Tomcat,
however when I try to run it in hosted mode with jetty I get the
following error:

org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
Configuration problem: Unable to locate Spring NamespaceHandler for
XML schema namespace [http://www.springframework.org/schema/security]
Offending resource: ServletContext resource [/WEB-INF/aop-
applicationContext.xml]

I've posted this to the Spring forums and they mention it's a
classpath issue, that there may be more than one instance of the
Spring Security jars on my classpath. I've double-checked my jars and
this doesn't seem to be an issue (especially since I package them with
my app and it works fine). I'm wondering if somehow jetty or GWT is
using a class that might be interfering with the resolution of the
namespace. Prior to incorporating security in my app it was running
fine in hosted mode, even with other Spring beans, so this makes me
think it's related to Spring Security (and not just Spring itself)
somehow.

Any ideas?

It could very well be. When running a more complex server side (i.e.
with Spring Security, etc), it's usually recommended that you use
-noserver. In GWT 1.5 with the Google Code gwt-maven plugin, you could
set it up to automatically copy configurations over to the embedded
Tomcat. I'm not sure how it works in 1.6.

Thanks for the tip. I think I may try that just to avoid having to
redeploy every time I want to test.

Can anyone who's familiar with the inner workings of GWT speak as to
why this may be happening?

Could you share more information with us ? It'll be difficult to help
without knowing your project structure, the tools you're using
(eclipse ? maven ? GEP ? ant ? netbeans), and how you're launching/
debugging your project.

Cheers,

Sure. I'm using Maven2 for my dependency management and project
structure, though I do have my spring config files and web.xml in the
GWT /war directory to simplify hosted mode. I use Eclipse 3.4.2 as my
development IDE. I'm using the latest GWT 1.6 release and these are
my spring dependencies:

<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>2.0.4</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core-tiger</artifactId>
<version>2.0.4</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>2.5.6</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
<version>2.5.6</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>2.5.6</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>2.5.6</version>
</dependency>
<dependency>
<groupId>net.entropysoft.transmorph</groupId>
<artifactId>transmorph</artifactId>
<version>2.1.2</version>
</dependency>
<dependency>
<groupId>aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.5.3</version>
</dependency>

Basically, I'm trying to use the latest of everything. Hope this
helps, and thanks for your help.

As a follow up, I switched to -noserver mode and it works just fine
now. Must've been a conflict with running it in the bundled jetty.
Thanks for the tips!

hi
I add the same issues with all namespace handler (aop, sec etc).
As a workaround I found the copy the spring jar (spring-aop, ...) solved the problem for the hosted mode.

Any other workaround for this? I want to keep my source tree clean and
followed http://blog.salvadordiaz.fr/2009/04/29/keep-your-source-tree-clean-gwt/
but I every time I lunch hm I get

Configuration problem: Unable to locate Spring NamespaceHandler for

XML schema namespace [http://www.springframework.org/schema/security]

Offending resource: class path resource [applicationContext-
security.xml]
