Yes.
When building your image, you have to compile all the classes into it.
So that means all the classes of the webapp as well. So if you don't
copy your webapp for the script to compile, no webapp classes ... Also
all the webapp Java classes and JARs will have to be included in the
image as well for annotation scanning.

Is it correct that following source from existing Tomcat Server needed
to be copied into $TOMCAT_STUFFED?
A. All files under conf folder (including war file)
B. All files under webapps folder
C. How about lib folder? Should it also be copied?
D. How about java source code(which are not deployed on Tomcat)

The doc is correct, so just use that:
- Copy config files from conf (obvious)
- Webapps go in webapps (unless the host appBase is something else)
And that's it.

Yes, avoid the juli file handlers. There's a jul file handler I think:
java.util.logging.FileHandler

I revised the source code by deleting "import java.util.*", and I
recompiled the java source and copied the war file into
$TOMCAT_STUFFED.
However, the error message remains:
Can't load log handler "1localhost.org.apache.juli.AsyncFileHandler"

Can't load log handler "2localhost.org.apache.juli.AsyncFileHandler"
java.lang.ClassNotFoundException: 2localhost.org.apache.juli.AsyncFileHandler

Use stuff from java.util.logging instead if juli doesn't work for you.
Or change the pom to add it. Juli makes things more complex with
Graal, so the pom doesn't have it.
As explained in the doc, the pom needs to be edited for needed dependencies.

Since the error messages are showing as above and the process is

package" unless I open another terminal to run maven command.
Do you have any idea about how to fix this error?

Well, there's no error there, so it's fine. The process is to generate
reflection metadata for your webapp depending on what it needs, so you
need to write a script that exercises all your paths in your webapp
[that would use reflection]. It's kind of like using your webapp
testsuite there. Once that is done, you should shutdown Tomcat as
usual, the metadata has been generated by the agent.
That is explained here:
https://tomcat.apache.org/tomcat-9.0-doc/graal.html#Native_image_configuration

Then you can move on to

Could we? Probably. Do we need to? Unlikely.

My expectation is that most clients aren't even including the host in 
the request line these days.


Non-ASCII hostnames are allowed these days. Depending upon when this 
comparison is done, the strings may or may not have been normalized. 
Case-normalization can be expensive if you want to be as encoding, 
language, etc. agnostic as possible.


Yes this is a theoretical risk but one I don't expect to materialize. My 
expectation is that clients new enough to use non-ascii host names also 
don't put the header in the request line or if they do, they make sure 
it matches the Host header.


Perhaps we could perform a byte-wise comparison first (which is very 
likely to succeed quickly) and, if that fails, fall-back to a more 
thorough normalization/comparison?


That is probably the way to go if we decide in the future that we do 
need to do the normalization first. In which case I'd lean more towards 
using toString() and then getting Java to do the comparison.

+1

The operations map is keyed on method-name which means that overloads
are not supported.

I suppose it's possible that the introspecter doesn't always get the
methods back from the reflection process in exactly the same order, and
the last one always wins. This would explain why it sometimes works and
sometimes does not work.

The best solution would be to explicitly-define this operation in the
MBeans XML-based registration. Then no introspection is necessary and we
always get the right method.

The operation is "addSslHostConfig".

The code I sent in the previous message works 100% of the time in

9.0.82.

In 9.0.83, it works about 50% of the time.  I can always query that the
operation exists, but roughly half the time it will fail with a JMX
exception saying that the operation does not exist.

I am not positive, but I believe the behavior in 9.0.83 might have to

with the fact that the catalina java code now has a one argument and

two

I'm pretty sure you got the explanation right. It is very similar to
using reflection here. You're doing the lookup based on the method
name, which matches something. However, if you want to avoid an error,
you also have to check that the arguments match, otherwise you're
going to randomly pick one of the two methods and fail half the time.

In our scenario ( as shown below ), the Host header value in the HTTP

and it's crucial that Tomcat, our web server, does not block or 
reject requests based on variations in the letter case within this 
header.


Request Line: GET http://HZN-OE-A079:8080 HTTP/1.1
Host header: hzn-oe-a079:8080

Just want to confirm that this property, now with a default of false, 
is supposed to reject requests based on the case of the host name.


David,

Host names are case insensitive so I can see the argument for making 
this comparison in a case insensitive manner.


However, the language in RFC 9112, section 3.2 is:

A client MUST send a Host header field (Section 7.2 of [HTTP]) in all 
HTTP/1.1 request messages. If the target URI includes an authority 
component, then a client MUST send a field value for Host that is 
identical to that authority component, excluding any userinfo 
subcomponent and its "@" delimiter (Section 4.2 of [HTTP]).



The key word for me in the above is identical.

We probably need to go back to the HTTP working group and clarify 
whether then intention was for that "identical" to be in a case 
sensitive or insensitive manner.


https://lists.w3.org/Archives/Public/ietf-http-wg/2023OctDec/0247.html

Based on that discussion, I am going to relax the check to case 
insensitive.

Our question is:

It seems to me that my solutions for now are:
1. sending SIGKILL signal to tomcat (this is very risky to me because
stopping like this in the middle of something may corrupt data - but this
situation is any way possible so I have to handle it)
2. wait for tomcat initilization procedure to finish and then trigger the
shutdown since we can do something in our wrapper scripts
Do you see any other possible solutions?



Did you try to terminate the process with SIGUSR1 instead of SIGKILL? I
usually terminate Java processes with SIGUSR1 if SIGTERM is not handled in
time and it still seems to do some cleanup while shutting down.


Try SIGTERM. You will still have to decide how to "avoid corruption" as 
far as your application is concerned.

The doc is correct, so just use that:
- Copy config files from conf (obvious)
- Webapps go in webapps (unless the host appBase is something else)
And that's it.

Use stuff from java.util.logging instead if juli doesn't work for you.
Or change the pom to add it. Juli makes things more complex with
Graal, so the pom doesn't have it.
As explained in the doc, the pom needs to be edited for needed dependencies.

Well, there's no error there, so it's fine. The process is to generate
reflection metadata for your webapp depending on what it needs, so you
need to write a script that exercises all your paths in your webapp
[that would use reflection]. It's kind of like using your webapp
testsuite there. Once that is done, you should shutdown Tomcat as
usual, the metadata has been generated by the agent.
That is explained here:
https://tomcat.apache.org/tomcat-9.0-doc/graal.html#Native_image_configuration

Then you can move on to

Is it correct that following source from existing Tomcat Server needed
to be copied into $TOMCAT_STUFFED?
A.  All files under conf folder (including war file)
B.  All files under webapps folder
C.  How about lib folder? Should it also be copied?
D.  How about java source code(which are not deployed on Tomcat)

I revised the source code by deleting "import java.util.*", and I
recompiled the java source and copied the war file into
$TOMCAT_STUFFED.
However, the error message remains:

Since the error messages are showing as above and the process is

Do you have any idea about how to fix this error?

In our scenario ( as shown below ), the Host header value in the HTTP

it's crucial that Tomcat, our web server, does not block or reject 
requests based on variations in the letter case within this header.


Request Line: GET http://HZN-OE-A079:8080 HTTP/1.1
Host header: hzn-oe-a079:8080

Just want to confirm that this property, now with a default of false, 
is supposed to reject requests based on the case of the host name.


David,

Host names are case insensitive so I can see the argument for making 
this comparison in a case insensitive manner.


However, the language in RFC 9112, section 3.2 is:

A client MUST send a Host header field (Section 7.2 of [HTTP]) in all 
HTTP/1.1 request messages. If the target URI includes an authority 
component, then a client MUST send a field value for Host that is 
identical to that authority component, excluding any userinfo 
subcomponent and its "@" delimiter (Section 4.2 of [HTTP]).



The key word for me in the above is identical.

We probably need to go back to the HTTP working group and clarify 
whether then intention was for that "identical" to be in a case 
sensitive or insensitive manner.


https://lists.w3.org/Archives/Public/ietf-http-wg/2023OctDec/0247.html

Based on that discussion, I am going to relax the check to case insensitive.

No.

Did you try to terminate the process with SIGUSR1 instead of SIGKILL? I
usually terminate Java processes with SIGUSR1 if SIGTERM is not handled in
time and it still seems to do some cleanup while shutting down.

Yes.
When building your image, you have to compile all the classes into it.
So that means all the classes of the webapp as well. So if you don't
copy your webapp for the script to compile, no webapp classes ... Also
all the webapp Java classes and JARs will have to be included in the
image as well for annotation scanning.

Yes, avoid the juli file handlers. There's a jul file handler I think:

Yes, if you take the path to stuffed that is mentioned in the docs, it
will be from the "main" Tomcat branch, which means Java 21 (it got
updated since). The module exists on the "10.1.x" branch as well,
where it is Java 11 instead, matching Tomcat 10.1. Don't be afraid to
change the release target and Tomcat version used in the pom.
I'll update the graal.html to at least point to the 10.1.x branch.
