[Jigar Naik]

Hi,

I have migrated My applcation from struts 2.0.9 to Struts 2.1.6.
I have resolved few issues but for bellow issue i need your guidance.

i am getting following exception in tokenSession

   
WARNING: Error setting value

The same thing was working in 2.0.9...

Thanks !!

What do you mean, "exception in tokenSession"? Under what circumstances do you get the exception?

[Jigar Naik]

i ment, while using <s:token /> i am getting exception.

below are the list of jar files in my classpath.

    
ognl-2.6.11.jar
mysql-connector-java-5.0.8-bin.jar
freemarker-2.3.13.jar
struts2-core-2.1.6.jar
xwork-2.1.2.jar
commons-fileupload-1.2.1.jar
commons-logging-1.0.4.jar
commons-io-1.3.2.jar
jstl-1.2.jar

functionality wise it's working fine. but i am getting session token null. so it's throwing null pointer exception

Bellow is the order of my interceptors in struts.xml

<interceptor-stack name="defaultLoginStack">
				<interceptor-ref name="servletConfig" />
				<interceptor-ref name="params" />
				<interceptor-ref name="loginInterceptor" />
				<interceptor-ref name="prepare" />
				<interceptor-ref name="chain" />
				<interceptor-ref name="modelDriven" />
				<interceptor-ref name="fileUpload" />
				<interceptor-ref name="staticParams" />
				<interceptor-ref name="params" />
				<interceptor-ref name="conversionError" />
				<interceptor-ref name="validation" />
				<interceptor-ref name="workflow" />
			</interceptor-stack>

bellow is the complete stack trace.

Am i missing any jar file ?

[David Newton]

First of all, it's just a warning, and your app is still running. Second of all, you don't show a token interceptor in your interceptor stack, so the token parameter isn't being taken out of the request, which is why it's trying to set it on the action.

[Jigar Naik]

allright...

Thanks a lot David.
