------------------------------------------------------
I think the issue is due to the stack because in Struts 2.3.28 I have this one :
<interceptor-stack name="defaultStack">
<interceptor-ref name="session"/>
<interceptor-ref name="exception">
<param name="logEnabled">true</param>
<param
name="logCategory">com.myapp.unhandled</param>
<param name="logLevel">ERROR</param>
</interceptor-ref>
<interceptor-ref name="alias" />
<interceptor-ref name="servletConfig" />
<interceptor-ref name="i18n" />
<interceptor-ref name="prepare">
<param
name="excludeMethods">submit,login,logout</param>
</interceptor-ref>
<interceptor-ref name="chain" />
<interceptor-ref name="scopedModelDriven" />
<interceptor-ref name="modelDriven" />
<interceptor-ref name="checkbox" />
<interceptor-ref name="staticParams" />
<interceptor-ref name="actionMappingParams" />
<interceptor-ref name="params"/>
<interceptor-ref name="conversionError" />
<interceptor-ref name="validation">
<param
name="validateAnnotatedMethodOnly">true</param>
<param
name="excludeMethods">input,back,cancel,browse,build</param>
</interceptor-ref>
<interceptor-ref name="workflow">
<!--
we exclude build so that we can
chain to build without failing if
original validation failed
-->
<param
name="excludeMethods">input,back,cancel,browse,build</param>
</interceptor-ref>
<interceptor-ref name="json">
<param
name="contentType">application/json</param>
</interceptor-ref>
</interceptor-stack>
And all is OK
And know I have replaced <param name="contentType">application/json</param> by
<param name="accept">application/json</param> and all fails all pages of my
Webapp
it's because I have only one stack for all my request and the accept cause some
trouble
And I Struts 2.3.28 when I called this :
http://localhost:8080/myapp/index.action the contentType is null and now for
all request I have accept set to application/json
