Jboss as7 org.apache.tomcat.util.http.Parameters.MAX_COUNT defaults to 512

[danjel]

Hi

I have recently been upgrading to jboss as7.1.0cr1b

and i have webforms that have more properties than the default (512)

I downloaded the Parameters.java from a nightly build and saw that it defaults to 512 if not the System property

org.apache.tomcat.util.http.Parameter.MAX_COUNT is set to something else.

This seems like a good idea, but where is a good solution to override it?

If i override it in my servlets init method it works as long as no webrequests are called before my servlet

The Parameters.java only loads this value once in a protected static final int:

public final class Parameter {

...

...

     protected static final int MAX_COUNT = Integer.valueOf(System.getProperty("org.apache.tomcat.util.http.Parameter.MAX_COUNT,"512)).intValue();

So once the Parameter class is loaded the value can not be overwritten...

I have tried to set this in the JAVA_OPTS in standalone, but this was ignored. I have also tried to set the value in my servlets init method

this one worked, but only if no requests were made during startup of jboss, which is never the case in a production environment.

Is there a way of setting this system variable properly or is the only solution to modify my forms to send much less data

Best Regards

I ran into the same problem today and changing the default by setting the system property inside standalone.xml worked for me. See https://docs.jboss.org/author/display/AS71/Admin+Guide#AdminGuide-Adding%2CreadingandremovingsystempropertyusingCLI for examples.

Setting the property via JAVA_OPTS should have worked too.

Hello Danjel

In standalone.xml add the following lines

<system-properties>

     <property name="org.apache.tomcat.util.http.Parameters.MAX_COUNT" value="5000"/>

</system-properties>

This works for me.

Thank you kindly, the suggested solution works!

Acctually setting the system property in standalone.bat. worked as well, but somehow, when i first tested it, it didn't.

Have a nice weekend everyone!

Hi *,

is there some setting for ajp protocoll as well?

Cause I have a problem with sending of a big post form with more than 1300 params

and it works well if I do it directly to our jboss server - HTTP Protocol.

Wenn I send the same request to Apache -> AJP -> jboss then I get an Exception.

My jboss is configured with property:

<system-properties>

     <property name="org.apache.tomcat.util.http.Parameters.MAX_COUNT" value="5000"/>

</system-properties>

but I can not find any ajp analoge.
