HTTP Status 500 - WELD-000335: Context is already active

I am using Tomcat 7 + weld-servlet-2.2.3 and this Context is already active error is frequently occuring in the website. I am using three filters: org.jboss.weld.servlet.ConversationFilter and org.apache.catalina.filters.SetCharacterEncodingFilter, and a custom filter.

Please give me some pointers in the right direction.

Solution

  • This issue was because of Tomcat Native Connector. It took a long time for us to identify that by trial and error.

    When the Tomcat Native Connector is installed, the threads weren't closed/reused properly, and that was why a previously used thread was still lingering around with the same context!
