How to disable "Invalid chunk ignored" from Tomcat ?

Hi devs,

Maybe, you have seen this Warning message from Tomcat app. Searching by Google. Finally, i found out two ways to disable this issue. If it’s interesting you so now let’s refer to and give your comment on this thread. Thanks !



The first one:

This error gave me a problem and I spent some time trying to figure out what it was before I was successful. So to save people time here it is.

When you call ‘XT.doAjaxAction’ it looks at the form and passes all of the elements along with the request. In doing this, if you don’t have a name for all of the fields it will create a query string similar to this:

Code: eName1=&=&eName2=val

The important part to note about this is the ‘&=&’ or ‘&=someValue&’. This causes the following error.

Code: 14, 2008 9:45:12 AM org.apache.tomcat.util.http.Parameters ProcessParameters

WARNING: Parameters: Invalid chunk ignored.

This does not actually stop any processing of the action. It just shows the warning. If you don’t want to see the error message be sure to add a value for the ‘name’ parameter for all of your form elements.


The second one:

To disable this WARNINGS for org.apache.tomcat.util.http.Parameters by adding the following line to

tomcat / conf /


One server restart and it is quiet!


I have just try in both of these ways.

The first one is too complicated. Result: Not working properly

The second one is easier then. Result: It’s fine.


God Helse !
