Tomcat Debugging Tips : Trace Full request content of all coming requests

Most of time the tomcat access log doesn’t provide full content of a request catched by tomcat server.

So to get a full view of content requests (with headers, cookies, parameters ….) you can use the following configuration.

1 – Add this configuration on web.xml file

<!--filters-->
<filter>
    <filter-name>requestdumper</filter-name>
    <filter-class>
        org.apache.catalina.filters.RequestDumperFilter
    </filter-class>
</filter>
<filter-mapping>
<filter-name>requestdumper</filter-name>
<url-pattern>*</url-pattern>
</filter-mapping>

2 – Restart your Server

3 – Then you will get console logs like following :
