Redirect to a custom page instead of login.html on session timeout with custom auth

Problem :  

How to redirect to the custom page with custom authentication once the session is timed out?

Default Behaviour :

By default, Jasperserver redirects users to the home/login page once the session ends.

Resolution : 

We can redirect users to a custom page. For this we need to add the bean "proxyExceptionTranslationFilter" in the applicationContext-externalAuth-<authType>.xml file under the WEB-INF folder: There we have to pass the url as a constructor parameter for bean "com.jaspersoft.jasperserver.api.security.externalAuth.wrappers.spring.JSLoginUrlAuthenticationEntryPoint". A sample for the same is given below:

<bean id="proxyExceptionTranslationFilter" class="com.jaspersoft.jasperserver.api.security.externalAuth.wrappers.spring.JSExceptionTranslationFilter"> 
    <constructor-arg index="0"> 
        <bean class="com.jaspersoft.jasperserver.api.security.externalAuth.wrappers.spring.JSLoginUrlAuthenticationEntryPoint"> 
            <constructor-arg index="0"> 
                <value>/externallogin.html</value> 
            </constructor-arg> 
            <property name="forceHttps"> 
                <value>false</value> 
            </property> 
        </bean> 
    </constructor-arg> 
    <property name="accessDeniedHandler"> 
        <bean class="com.jaspersoft.jasperserver.war.JRSAccessDeniedHandlerImpl"> 
            <property name="errorPage" value="/WEB-INF/jsp/modules/system/AccessDeniedPage.jsp"/> 
            <property name="themeResolver" ref="themeResolver" /> 
            <property name="themeSource" ref="themeSource" /> 
            <property name="localeResolver" ref="filterLocaleResolver"/> 
        </bean> 
    </property> 
</bean>

Now save the applicationContext-externalAuth-<authType>.xml file and restart the server.
