--add-opens gives me unknown module
Hey everyone: I am trying to deploy a Spring Boot 3.0.4 application to a Tomcat 10.1.7 server. The machine has java 17 installed. When I try to loan tomcat, it gives me this error: java.lang.reflect.InaccessibleObjectException: Unable to make field private static final java.lang.reflect.Method jdk.proxy3.$Proxy74.m0 accessible: module jdk.proxy3 does not "opens jdk.proxy3" to unnamed module @14022c95 It seems strange to me the module can’t pen itself. But, I added these lines in setenv.sh to try to work around it: JAVA_OPTS="$JAVA_OPTS --add-opens jdk.proxy3/jdk.proxy3=ALL-UNNAMED" export JAVA_OPTS But, now, when I run tomcat, I get this: WARNING: Unknown module: jdk.proxy3 specified to --add-opens And I still get the exception. Any ideas what I need to do here? Thank you, Neil -- Neil Aggarwal, (972) 834-1565, http://www.propfinancing.com We offer 30 year loans on single family houses!

My environment is 4 virtual hosts with about 9-10 web applications on each. The web apps are already expanded in the webapps folder. So there are no war file expansions involved. The first time after I reboot the server each web app takes ~15-20 seconds to start up which is an eternity to get the full Tomcat up. But if I stop TC and restart it, everything starts up in just a few seconds. This same situation happens on my local windows development machine with eclipse. After starting eclipse, the first TC start I watch the stdout log creep along saying it loaded webapp xyz in 18 seconds... then loads the next web app in 16 seconds, etc. But if I stop TC and restart, immediate quick load. No errors or anything. No messages about taglib searches that I've seen. Simply starting a web app msg, wait 18 seconds completed. It's now gotten so bad in production TC taking so long to start that the heath checks are failing, terminating the server, spinning up a new one, and the process repeats again. Any ideas what might be causing this? Thanks.

RE: is too quick to respond
John: > If anyone has a moment, can you have a quick look and see if what I am > proposing seems acceptable. Thinking about when a large file (Such as a war file) is being uploaded to the server, we don't want Tomcat to reload it until after the file has completed upload and is fully formed. How does Tomcat test if a file has been updated? I assume it uses File.lastModified() or something similar. Does anyone know the detailed nuts and bolts of how that works? Does last modified keep changing as the file is uploading or is it just changed at the start of the upload? Is the behavior the same or different across platforms? These questions should be taken into account when designing the solution.

How to access multiple virtual hosts with a single SSL instance?
Hello: Up until now, I have always run Apache in front of Tomcat. I am wondering if I should change to using Tomcat as a standalone server. My concern is how to use multiple virtual hosts with a single SSL instance running on the standard https port. With httpd server, I can access my webapp using the directory name in the URL. For example, if I have an app called app1, it uses URLs that look like this: http://www.app1.com/app1/index.html https://ssl.example.com/app1/index.html If I have another app, it would use urls like this: http://www.app2.com/app2/index.html https://ssl.example.com/app2/index.html This is because mod_jk will forward anything with the app name as the first part of the URL to Tomcat. >From what I am reading in the documentation, Tomcat uses the hostname to determine the webapp to use. That won't work since they need to use the same hostname in ssl mode. Thanks, Neil -- Neil Aggarwal, (972) 834-1565 We lend money to investors to buy or refinance single family rent houses.

It seems to me if jk is confused about the number of backend connections, it may not be connecting correctly to Tomcat. That seems like it would cause the behavior I am experiencing.

I am using mod_jk 1.2.30 which I built from the source tarball.
My application just locked up so I did a tail -f
on the mod_jk log and made a request to it.
Here is what generated in the log:

I took a look at the tomcat catalina.out and do not see any errors there.
The CPU is empty and the RAM is available.
I telnet to 127.0.0.1 port 8009 on the machine, I get a connection,
so something is listening on the port.
If I do a ps aux | grep java, I see two processes for tomcat which is
normal.
I checked the mysql log and do not see any errors. I did a show innodb
status and do not see any deadlocks in the database.
I am attaching the properties for my jk configuation and a screen shot of
the
JK Status in case it helps.
What is really strange is the JK Status page says -48 connections. It seems
like that number should always be positive or zero but not negative.
I appreciate any help you can offer.
Thanks,
Neil

Application stops responding, jk worker in error state
Hello: I have Tomcat 6.0.26 running behind Apache and am using the JK Connector to communicate between them. My application stops responding on occasion. I added the jk status page to the web server and checked it when the application becomes non-responsive. The tomcat worker has this info: Worker Status for tomcat Type Hostname Address:Port Connection Pool Timeout Connect Timeout Prepost Timeout Reply Timeout Retries Recovery Options Max Packet Size ajp13 localhost 127.0.0.1:8009 600 0 0 0 2 0 State Acc Err CE RE Wr Rd Busy Max LR LE ERR 6 (0/sec) 2 0 0 4.8K (7 /sec) 12K (18 /sec) 0 2 663 Fri, 18 Jun 2010 00:06:17 CDT Note the state is ERR.

In my experience, Tomcat has problems reloading webapps
on occasion. This may work 80% of the time, but you
are still going to have to restart Tomcat fairly often.

I think you need to use mod_jk. That will allow
you to use connections to port 80 and 443 for
both apache and tomcat and you wont have to use
redirects.

RE: synchronizing in tomcat
> Does tomcat offer any mechanism for locking servlet executions? I think you are going to have to take care of this in your application code. At first thought, I would create a class with synchronized static methods to do each of your processing tasks. That way, you are guaranteed only one method is executing at a time. You have to be careful to avoid deadlock so you better call the methods in a pre-set order.

For that, you need to have your firewall forward port
443 to port 8443 on Tomcat.

There is no restriction from Tomcat. If you have 3.5 GB RAM in the machine, I would set the heap no larger than 3 GB. Considering you are at 256 MB now, set the max to 1 GB and it should be plenty large for you. If you stil run out of RAM, you probably have a memory leak in your application.

You will need to put both your database and tomcat
app on a server that supports servlets.

The error.action exists and loads correctly:
