Maximum number of parameter passed in a post

I get this error:

Exception during request processing:
Caused by javax.servlet.ServletException with message:
"Parameter count exceeded allowed maximum: 512"


There seems to be a limit on the number of parameter passed in a post.

How could I extend this limit in JBoss?

Answer

The number of parameters was limited in all web servers to plug the hashmap collision denial of service attack.

You can raise the limit by adding the following system property to the configuration file (e.g. standalone.xml):

<property name="org.apache.tomcat.util.http.Parameters.MAX_COUNT" value="10000"/>
