Tomcat 9 - failed to set property [packetSize]

[valsaraj pv]

Hi,

WARNING [main] org.apache.tomcat.util.digester.SetPropertiesRule.begin
> Match [Server/Service/Connector] failed to set property [packetSize] to
> [65536]

I see this warning when migrating from Tomcat 8 to 9 on JDK 8. The warning
went away when packetSize="65536" property removed.

How to set this in Tomcat 9?


Thanks!

packetSize is a valid attribute for the AJP Connectors in Tomcat 9.

Please provide the full content of the Connector element exhibiting the
issue.

Thanks for your reply Mark.

Is packetSize property still available in http connector? I got this
warning when I added in it.

It is possible to add this property in ajp connector but when I access via
Apache proxy, it shows connection closed. When this attribute is removed
all works fine. But this behaviour is different from Tomcat 8, where this
property worked fine with the same front end Apache proxy. Any
pointers would be appreciated.

Thank you very much!

That property has never been valid for an HTTP Connector for any Tomcat
version.

You'll need to provide your full proxy configuration from httpd and the
full <Connector> element(s) from Tomcat for us to be able to help you.

Kind regards,

Here is the configuration details:

Tomcat 9:

Tomcat 8:

Following error in Tomcat 9 when packetSize="65536" added:

You have only changed the packet size on the Tomcat side of the
connection. The httpd side is still using 8192. That will work up until
the point where Tomcat needs to return a response bigger than 8192
bytes. At which point it will fail. I suspect the response in the Tomcat
8 case was just less than 8192 bytes whereas in Tomcat 9 something made
it just over 8192 bytes.

You must configure the same packet size for both httpd and Tomcat.

You can either:
- remove the packetSize attribute from the Tomcat Connector
or
- set ProxyIOBufferSize 65536 in httpd.conf

Thanks Mark!
It works fine after removing packetSize.
