Thank you. I dug around more after your pointers.
I am using 8.0.x (I should have said that). I found a few things
problematic with JMX around data sources.

I ended up calling MBeanRegistration.preRegister() on the data source.
This way I don't have to cast it to Tomcat classes. It does the job,
but not in a right way. I looked around and I noticed these facts:

- DataSource.createPool() is always called anyway when the data source
is created, by DataSourceFactory.createDataSource()
- Pool object is not supposed to be registered JMX object, there is a
special JMX object that is created is jmxEnabled is true.
- DataSource implementation looks like a JMX bean, it implements
MBeanRegistration and ConnectionPoolMBean, but trying to register it
directly throws a non-compliant JMX bean exception
- MBeanRegistration implementation of the DataSource violates API
contract. It doesn't return the ObjectName that is being used, and it
actually registers the bean with JMX (it shouldn't)

I had problems with that last fact, because if I register the bean, I
need to clean it up on shutdown, but I can't get the actual name that
the bean is registered as (except for copying the code that
preRegister ends up calling). I ended up fishing the bean out by
querying it before unregistering it.

I hope things are, in fact, better in 9.

Thank you,
  Pawel.

Fw: Re: Fw: No movement at Debug mode

[Karen Goh]

Hi chris,

The database problem has been resolved cos apparently, there is a old version 
of J-connector that is not removed inside Eclipse.

But, now I am facing the No movement at Debug mode again.

I used to be able to received logger infor when when run debug that shows me 
the stack when the 'compiler' steps thru the programme but I am not seeing this 
now.

All I get is Daemon thread running...

Furthermore, I am getting the below log :

Could you kindly explain why I am getting 404 even though I am able to get the 
tutorRegister.jsp and then there is a 404 at Checkbox.js... which I do not 
understand the error.

The addTutor which is my controller servlet I got a 200 but I am not seeing 
data being inserted into my database.

Hope you could advise me. Tks.

Have you seen the Specifications page in the Wiki?
https://wiki.apache.org/tomcat/Specifications

I updated the whichversion page with a link to there (r1822243).

Minimum Java version == Java EE version (at least for Tomcat 7.x, 8.x
and 9.x).

Tomcat doesn't implement the full Java EE spec so I'd be cautious about
listing it in case it causes confusion. If we can find the right wording
to use I wouldn't have any objection to adding a Java EE column.

What will happen now Java EE is moving to Eclipse is a whole other issue...

tomcat version question

[Robert J. Carr]

Hello.

There is a "which version" page on the main site which is really useful,
and it lists all the versions of the various specs related to the version
of tomcat, but a really important one IMO that is missing is the Java EE
version, so I can look up the api docs.

Is there a reason why this is omitted?  Currently, I have to look up the
servlet spec, and then cross reference that with the Java EE to find the
appropriate docs.

Or am I missing something?

Thanks-
Robert

Ping.

The current list of ideas is here:
https://cwiki.apache.org/confluence/display/TOMCAT/Tomcat+Training+Course

More ideas are welcome.

Based on what we have so far, a "Tomcat for system admins" course aimed
at experienced system admins who are unfamiliar with Tomcat looks like
the best fit.

Any feedback regarding location?

Tomcat should merge the init-param entries. The rules for merging the
default web.xml file are as follows.

1. Web fragments, annotations etc. are merged into the main web.xml as
per the Servlet spec merge rules to created an updated main web.xml.

2. The default web.xml is them merged into the updated main web.xml as
if the default web.xml was a web fragment again following the Servlet
spec rules with one exception. If there is a conflict, rather than
triggering an error, the updated main web.xml always takes precedence.

The code that does this is in ContextConfig and WebXml.

Re: How to make database connection pool show in JMX

[Keiichi Fujino]

Hi

The Docs of jdbc-pool describe like this.
==
If you're running outside of a container, you can register the DataSource
yourself under any object name you specify, and it propagates the
registration to the underlying pool. To do this you would call
mBeanServer.registerMBean(dataSource.getPool().getJmxPool(),objectname).
Prior to this call, ensure that the pool has been created by calling
dataSource.createPool().
==
http://tomcat.apache.org/tomcat-9.0-doc/jdbc-pool.html#JMX

Thus you must register the DataSource as MBean.
