Chuck, to get rid of the warnings...

3-Apr-2024 08:30:22.970 WARNING [Tribes-Task-Receiver[station-Channel]-1] 
org.apache.catalina.ha.session.ClusterSessionListener.messageReceived Context 
manager doesn't exist:[##0001]

I moved my  Manager element form the server.xml to the context.xml

 

That got rid of those warnings
But Now cat log shows these new warnings

Do I need to configure something different?  Some how allow more 
deserializeSessions?

Correct. To quote from the Tomcat doc:

The IP broadcasted is java.net.InetAddress.getLocalHost().getHostAddress() 
(make sure you don't broadcast 127.0.0.1, this is a common error)

Unless the two JVMs are deployed on the same VM, you cannot use 127.0.0.1 and 
expect them to be able to communicate with each other.

Here's an old e-mail describing the issue and one way of addressing it:

https://marc.info/?l=tomcat-user=118764351104059=2

The gist of it is this:

1. check what name the command `hostname` spits out 2. make sure that 
/etc/hosts contains that hostname and IP address

This must be done on each VM, of course.

Returning localhost is typical for systems that use DHCP to obtain their IP 
addresses, such as my MacBook:

jshell> java.net.InetAddress.getLocalHost().getHostAddress();
$1 ==> "127.0.0.1"

Chuck,

So you mean we use the VM's  IP as the address value below
Instead or using the value of   auto  ?

Which explains why they can’t talk to each other over 127.0.0.1.


> What do you mean each containers published IP


Each VM or container will have an assigned, individual IP address so it can 
communicate with networks outside of the VM (eg, the host machine or real 
world). You must use each VM’s assigned IP address - not 127.0.0.1 - in the 
clustering configuration to allow the two VMs to communicate with each other.

Are both Tomcat instances running on the same system (VM or real)?

Tomcats are two different VMs


> But both servers report -> no active members in cluster group


Indicates they can’t see each other, so they could be on different systems or 
in separate VMs (containers).

This long random ID generation is typical for a low-entropy VM or container 
rather than a real system. If the two Tomcats are in separate containers, 
you’ll have to configure clustering to use each container’s published IP 
address rather than assuming they can share the same loopback network.

What do you mean each containers published IP

And on the other server the receiver is bound to   127.0.0.1:4001

But both servers report -> no active members in cluster group

Here is how I have clustering set up on server one



   

  

 

 

  

  

  
  
  

  


On the other server I just changed  the member ship  to a different port   
port="45564"
And reciver port to   a different port also 
   port="4002"


In my application level web.xml on both servers I have included the needed tag


What am I missing here?

clustering logging erors Tomcat10 with Java 17

It looks like to me, this machine successfully sent a session data state msg to 
the other machine in the cluster, but 60 sec later the other machine did not 
respond with with its session data state

Tomcat 10 clustering is not replicating session data

[Rick Noel]

Hello,

I am running Tomcat 10.1.20 with Java 17

But our session data is being lost.

Here is snippet of the clustering I have defined..





 


 

   

   


   

 

   

   

   

   

 


 



 


Notice in sessionAttributeNameFilter that one of the session attributes I want 
replicated is   -> logged_in_user
We have to include the session data we want replicated here Correct?
logged_in_user is one we want replicated, its value is a String

When I run my app this code runs ->

public class Utils {
   public static String getUserName( HttpServletRequest request )
   {

  return (String) 
request.getSession().getAttribute("logged_in_user");
   }
}

That code returns a null value, indicating that the session value is not found.

Does anyone see something wrong with how I defined the clustering?

This below comes from the Catalina.out log and indicates there is an issue with 
clustering...

SEVERE: Manager [##0001]: No session state sent at [4/16/24, 12:48 PM] 
received, timing out after [60,074] ms.

Our live environment has two app server machines being fed by one loadbalancer.

In our dev environment, that has just one machine, this same session data can 
be extracted.
But not on the live 2 machine environment

.intermittent InvocationTargetException errors

[Rick Noel]

Hello,

I am using Tomcat 10 with java 17.

I am getting itermitant jsp compile errors below.

Some times the page compiles correctly but sometimes the page hits result in 
below errors

java.lang.reflect.InvocationTargetException
at 
java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at 
java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77)
at 
java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
at java.base/java.lang.reflect.Method.invoke(Method.java:568)
at com.radiovoodoo.display.EvalExpr.evalIdentifier(EvalExpr.java:317)
at com.radiovoodoo.display.EvalExpr.eval(EvalExpr.java:57)

I found this explanation for possible cause..
Normally "java.lang.reflect.InvocationTargetException" occurs when java 
compiler finds 2 different classes with same name in 2 different packages.
When you are importing both classes at a time and when you are trying to create 
object of that class it throws "java.lang.reflect.InvocationTargetException" 
exception .
The solution is that when you are creating the object of the class use package 
name also along with class name so that compiler knows what class it has to use.

I looked at my code in the jsp and the code in question could be mistaking for 
two different classes.
My code is meant to use  java.util.Timezone but my code also has a  
com.radiovoodoo.customer.Timezone class
So I thought ah ah will specifical declare the class the I want, so I changed
From
private TimeZone customerTimeZone;
to
private java.util.TimeZone customerTimeZone;

so that the compiler will not think to use com.radiovoodoo.customer.Timezone 
but instead always use java.util.TimeZone
But this had no effect.

I still get intermittent java.lang.reflect.InvocationTargetException
Could this be a possible bug in   the class tomcat 10 uses to compile jsp   ->  
org.apache.jasper.servlet.JspServlet

Is there a different JspServlet class I could use to test that theory out?

RE: [EXT]Re: [EXT]Re: Tomcat 10 session replication fails

[Rick Noel]

Hi Chuck,
Your suggestion did not work.

I defined Membership as suggested...


and still getting this in the logs

org.apache.catalina.ha.session.DeltaManager.startInternal Starting clustering 
manager at [##0001]
15-Apr-2024 07:55:36.744 INFO [main] 
org.apache.catalina.ha.session.DeltaManager.getAllClusterSessions Manager

Do you think the transfer is not happening because the application is only on 
one machine?
Our Production environment will have  our application on two machines but in 
our dev environment we have only one machine in the "cluster". So we really do 
not have a "cluster" environment.
Again, we would like to know is going on before we introduce clustering in our 
live environment.

We are using Java 17 and Tomcat 10

There’s a cluster configuration option that may be coming into play here: 
localLoopbackDisabled. Once upon a time, the JDK method:
MulticastSocket.setLoopbackMode(boolean disable) did the opposite of 
what one might think from just the method name - passing in true disabled local 
receipt of multicast packets. That method has since been deprecated, and Tomcat 
currently uses this method:
 DatagramSocket.setOption​(SocketOption name, T value) which, at 
least in Java 21, operates as you might expect from the name - specifying true 
enables multicast loopback.

However, there’s some interesting logic in Tomcat's handling of 
localLoopbackDisabled that can inverts the config value based on the Java 
level, along with this comment:
Java < 14, a value of true means loopback is disabled. Java 14+ a value 
of true means loopback is enabled.

Having not dug into the JRE source code for the various Java versions, I’m not 
yet convinced the version checking logic is correct. You might try setting 
localLoopbackDisabled to true in your  config to see if that 
has an effect on your dev system.

Also, let us know what Java version you’re using.

Thanks Chuck,

We are getting closer
Changing ports from the 5000 range to the 4000 range stopped two errors 
But now I get this..

INFO: Manager [##0001]: skipping state transfer. No members active in cluster

How to I make the member machine in the cluster active?

Likely. From the Tomcat clustering doc:

If your Tomcat instances are running on the same machine, make sure the 
Receiver.port attribute is unique for each instance, in most cases Tomcat is 
smart enough to resolve this on it's own by autodetecting available ports in 
the range 4000-4100

You appear to have configured 5001 as the receiver port on both.

Tomcat 10 session replication fails

[Rick Noel]

Hi,

We have our app running on Tomcat10 and doing clustering,but are getting the 
following errors seen int the Catalina log...

Apr 11, 2024 8:14:43 AM org.apache.catalina.ha.session.DeltaManager 
waitForSendAllSessions
SEVERE: Manager [##0001]: No session state sent at [4/11/24, 8:13 AM] received, 
timing out after [60,068] ms.
Apr 11, 2024 8:14:43 AM org.apache.catalina.ha.session.DeltaManager 
getAllClusterSessions
WARNING: Manager [##0001]: Drop message [SESSION-GET-ALL] inside 
GET_ALL_SESSIONS sync phase start date [4/11/24, 8:13 AM] message date 
[4/11/24, 8:13 AM]
11-Apr-2024 08:14:43.456

The error, to me, indicates that the session data is not being sent out.

We are running this app in our dev environment, and in this dev environment the 
app runs on only one machine.
In our live environment the app runs on two machines and traffic goes through a 
load balancer.
This may be a dumb question but are we getting these errors because we are 
running the app on only one machine, and clustering cannot be done on one 
machine?
We need to better understand these errors before we can move to tomcat 10 
clustering into our live   2 machine environment

This is how we have clustering defined in the server.xml...

RE: [EXT]Re: unable to set compression, compressionMinSize and compressableMinemType attributes in UpgradeProtocol element

[Rick Noel]

Mark you were correct. I, needed to move those attributes to the Connection 
element.
Plus on top of that I had this misspelled attribute  compressableMinemType
should be compressibleMimeType

In your opinion, should we use the Upgrade UpgradeProtcol protocol?
I mean does not the semantics of its name imply it is better?

You haven't provided information on the Tomcat version you are using.
I'm assuming 10.1.x.

https://tomcat.apache.org/tomcat-10.1-doc/config/http2.html

Search for compressionMinSize.

That seems ... unlikely. Please provide the Connector configuration and the

It depends. YMMV.

RE: [EXT]Re: how to define database resource in just context.xml or server.xml

[Rick Noel]

Yes and that is just what we are trying to do.  On our dev servers all five 
different applications share the same database.
So it would seem best to have the resource link in the context.xml and not 
complicate things up by putting the database link in each web application's 
web.xml.

The idea being that a developer working on one application would think if he 
changed the web.xml for his application, hey maybe I should change the other 
application's web.xml also

The only reason you might want to touch context.xml is if you want to provide 
the same resource link to all web applications rather than have to specify it 
in each web application.

Yeah I like the idea of using the Resourcelink  in the context.xml and then 
keep the defining of that datasource in the server.xml

That's definitely a possibility as well.

I work on a small team and so separating the JDBC definition from the link 
doesn't make much sense so we don't do it. We also don't like polluting our 
server.xml file so everything goes into META-INF/context.xml.

You really should never change CATALINA_BASE/conf/context.xml, though.

talking about is on our dev machine, where we want to run all 5 apps on the one 
web server. 

The context.xml has global enviroiment variables (like mail server related 
vars) that all the dev applications use.
All the different dev applications also use the same database.

So that is why we define resources in the context.xml  file

You really shouldn't have anything custom in CATALINA_BASE/conf/context.xml. 
That will affect every application deployed on the server. Perhaps you only 
have a single application deployed, but things can get really confusing when 
you edit that file. 
It also makes upgrades more difficult.

I would recommend taking your  from CATALINA_BASE/conf/context.xml 
and putting it into the proper place: 
your application's META-INF/context.xml file. You will need to surround it with 
 ...  since that file defines the context.

If you have  in your CATALINA_BASE/conf/server.xml file, you should 
remove it. If you want to disable auto-deploy, then you can always copy your 
application's META-INF/context.xml file into 
CATALINA_BASE/conf/[engine]/[host]/[contextpath].xml.

Finally, you should be able to delete your  from your 
CATALINA_BASE/conf/server.xml file entirely.

Do you have anything in your web.xml that is related? For example:

   
 jdbc/foo
 javax.sql.DataSource
 Container
   

I have one of those in my web.xml, but it's not clear to be whether or not I 
actually need it. I have *one* of them but my application uses two different 
JDBC resources. Both are declared in META-INF/context.xml and both are 
available to the application.

I think you need to use  in web.xml when you define "global 
naming resources" in server.xml. But if you put them into META-INF/context.xml 
it's obvious that (a) they aren't global and (b) the application expects them.

So I would remove any global naming resources you may have in server.xml and 
also remove anything you don't need in web.xml.

Doing all this will make upgrading Tomcat much easier.

FW: [EXT]Re: how to define database resource in just context.xml or server.xml

[Rick Noel]

Chris,

I found I could use a ResourceLink element and put it in my context.xml file.
The name in that ResourceLink is the name of resource that I have fully defined 
in my server.xml.
Sot the context.xml points to the fully define resource which is in my 
server.xml

So snippet from my context.xml file is.





  
   
   


And snippet from my server.xml is.

Which context.xml are you talking about? The one in CATALINA_BASE/context.xml 
or the one in your application's META-INF/context.xml?

Have you defined your  in CATALINA_BASE/conf/server.xml, or are you 
using only META-INF/context.xml?

how to define database resource in just context.xml or server.xml

[Rick Noel]

Hello,

Can someone tell me why I need to have my database source defined in both my 
context.xml and server.xml?
I thought we are suppose to define it in only one location?

I can only log into my app if I have it defined in both my context.xml and 
server.xml


Below  is my database resource   as defined in server.xml..

I have xxx out postgres URL for security reasons





 


  



Below is my database resource   as defined in context.xml

RE: [EXT]Re: [EXT]Re: performance tunning of Tomcat 10

[Rick Noel]

Chris,
 my bottleneck (app slowness to respond is the at the database connection max), 
I am not even going to try and adjust minThreads and maxThreads.
When I tried to increase maxConnection to our database from and existing 
connection max of 20, to a new connectionMax of 50, I got errors, see attached 
snapshot.

I was able to raise the maxConnection to database up to 30 with no errors, so I 
am just going to deploy at that level until we upgrade our Postgess database
We are using a really old Postgres and plan in the near to future to upgrade 
that database.

BTW,
I did find and use the Apache Benchmark tool and was able to see how our app 
responses with a test requests of 1 and concurrent requests of 40 and those 
results look good to me with worst response time of only  1000 miliseconds.

Okay, you need to get better information. Check out this presentation on Tomcat 
monitoring:

https://tomcat.apache.org/presentations.html#latest-monitoring-with-jmx

There is a lot in there, but I do talk about checking on the request processor 
to see how many requests are in-flight at once. You can do the same with your 
database pool.

You'll want to grab samples of those things at regular intervals to see how 
they correlate. I suspect you know when your peak times are, so schedule the 
samples to be taken during that timeframe. You could even sample once per 
second if you wanted to -- the calls are pretty inexpensive.

What is your goal?
Our application is a sip phone call handling application.(A voice response xml 
application)
The goal is to not have  call bottleneck at peak call volume.
Sometimes too many folks call at one time hit our app and calls are not handle 
correctly.

Okay.
Well I do not have actual traffic info down to the sec,
But from the application logs I know that that points in the day more than 300 
calls can come in

That's the only way to enable h2. Well... you could use Http11Nio2Protocol, 
too. NIO is the default protocol so you don't even need to add that 
specifically if you don't want to.

Back to threads.

Each thread (unless you go virtual, but that's not really production-ready IMHO 
at this point unless you have very strict circumstances where it will work 
great for you) takes up a bunch of memory, so you can't just set maxThreads=1M. 
Threads take "time" to start, but it's not really that much. If starting and 
stopping threads is what is making your application slow, than you have a very 
high-performance application and environment indeed.

Your question as stated is unanswerable.

You say you are sometimes hitting 500 connections. The default maximum number 
of connections is 1 and you are only using 500. That means you aren't being 
flooded, which is a Good Thing. (BTW: How are you measuring "how many 
connections" you have? Make sure you are measuring the right thing...

I am estimating the actual connections just based on application call logs.

Is your *current* maxThreads set to 500? If so, then your thread pool maximum 
is set to your high-water mark which seems like it should be fine. If you set 
your maxThreads to 1000 you won't get any benefit because only 500 requests are 
ever being sent at once, right?

What else does your application do?
Our application is a sip phone call handling application.(A voice response xml 
application)

For example, if you have a thread-pool max-threads of 1000 and your application 
uses an RDBMS for every request but your db connection pool size is more like 
10, then many threads waiting on a small number of connections gets you 
absolutely no benefit. You'd have to make changes elsewhere in your application 
in order to make use of those extra threads.

Similarly, if you have a big thread pool and a big db connection pool, but your 
database performs slowly, then having all that power on the application server 
doesn't really help you.

Yes our app is using a database  (we use Postres)
And yes I assume that is our bottleneck
Our tomcat context.xml defines that database maxConnction to be only 
maxTotal="20"
We have other apps  and that hit this same database, so we define low maxTotal  
on each  server so each server can have only limit connection access to the 
database
I am thinkingit would be best to try and NOT optimize  minSpareThreads and 
maxThreads but instead to determine what is the optimal
Database  c

performance tunning of Tomcat 10

[Rick Noel]

Hello,

I was wondering if the apache foundation has any tools we can use to fine tune 
Tomcat 10.
Tools to deteming how to set the best heap size for Tomcat startup and the best 
connection attributes of minSpareThreads and MaxThreads.

I know my application at times will reach 100 concurrent connections and some 
times goes has high as 500 connections.
Should I boost minSpareThreads and maxThread values of what I plan to use below?

Or why would we not just set very high minSpareThreads and maxThread values
like minSpareThreads =300  and maxThread=1000

This is a snippet of my server.xml



  
   

 

Also, am I good with setting  
protocol="org.apache.coyote.http11.Http11NioProtocol"
And then setting 

That will tell Tomcat to do HTTP2 Correct?

This is an allow-list which is much more secure than a deny-list.

It's a regular expression, so you can feel free to get super-creative with the 
expression if you want to effectively create a deny-list with one item.

Honestly, this is probably some technical dept worth paying off at this point.

Another option would be to store the object in a wrapper in the session that 
*is* serializable but it doesn't actually try to serialize the object it wraps.

I did one of these ages ago for similar reasons: I didn't want to go change all 
those classes to be Serializable. Here it is:

public class TransientObjectWrapper
 implements Serializable
{
 private static final long serialVersionUID = -4694896879363833304L;

 private transient final T _o;

 public TransientObjectWrapper(T o) { _o = o; }

 public T getWrappedObject() { return _o; } }

Using this plus a craftily-written Filter, HttpServletRequestWrapper, and 
HttpSession implementation would allow you to do this kind of thing without any 
failures.

Or you could just configure Tomcat's already flexible allow-list for session 
attribute names.

You set that to the attributes you DO want to replicate, not the ones you don't.

RE: [EXT]Re: Tomcat session replication issue - java.lang.IllegalArgumentException: setAttribute: Non-serializable attribute :

[Rick Noel]

So setting...   
sessionAttributeNameFilter="customer"
does not work,
 still getting the error  java.lang.IllegalArgumentException: setAttribute: 
Non-serializable attribute : customer

Do I need to set this also?

sessionAttributeValueClassNameFilter= 
"java\\.lang\\.(?:Boolean|Integer|Long|Number|String)|com.radiovoodoo.customer.Customer"

I am thinking no config setting can stop this error.

I am thinking  I must alter my Customer code and make that class implement 
java.io.Serializable.
And that is  what I was hoping not to do. (alter the application code itself)

The expireSessionsOnShutdown attribute is only available for the DeltaManager, 
not the BackupManager. See:

Can you watch the HTTP headers for your interaction to see what's happening? 
The browser should be sending JSESSIONID cookies with each request. If the 
server isn't sending any Set-Cookie header, the browser should leave things as 
they are.

Please note that Tomcat will send Set-Cookie when a session is created (by 
default, every JSP will create a session IIRC if you declare it to use 
sessions), plus Tomcat will rotate the session identifier as part of the 
authentication process. If you have code on the client that is storing the 
session and using it later, if your session id is being updated during 
authentication you need to make sure it gets updated everywhere the client is 
using it.

No, the cache here refers to the client's resource (e.g. page, image,
etc.) cache. It has nothing to do with what's happening on the server.

Are you properly encoding your URLs in your page like with 
HttpServletResponse.encodeURL()? If you are using cookie-based session-tracking 
it probably won't matter, but it's best practice to always do that to ensure 
your URLs are generated properly.

RE: [EXT]Re: 404 for j_security_check

[Rick Noel]

I really only want auth once

All hits to jsp pages after a successful login do not trigger the Auth process 
again.

But hits to java action class servlets do trigger the Auth process

Its  like session data is being lost for some pages but not for others

I was thinking maybe this is reason..


The Expires header specifies when content will expire, or how long content is 
"fresh."
After this time, the Portal Server will always check back with the remote 
server to see if the content has changed.
Most Web servers allow setting an absolute time to expire, a time based on the 
last time that the client saw the object (last access time),
or a time based on the last time the document changed on your server (last 
modification time).

In JSP, we can set caching to forever using the Expires header like so.

response.setDateHeader("Expires",Long.MAX_VALUE)

BUT I do not want to change my application code, I just want to tell Tomcat 10 
to stop
Expiring cache so that session log in data is not lost

My main question is  
I want to know how to configure Tomcat 10 to not loose session data that tells 
the user has successfully logged in

This is actually expected, since j_security_check is only supposed to be used 
when the container (Tomcat) interrupts a user workflow to request 
authentication.

Are you doing what I call a "direct login" where you have a "login page"
that most users hit first. Like from example.com/app/ where there is no initial 
request for a protected resource? Or are your users always (1) requesting a 
protected resource then (2) Tomcat requests authentication then (3) the user is 
forwarded to the resource originally requested in (1)?

Those NONE lines look weird to me. 
Why are you explicitly specifying those? What part of your configuration 
actually requests authentication and authorization?

RE: [EXT]Re: [EXT]Re: jakartaee-migration-1.0.7 migration tool failure

[Rick Noel]

Thank you so much Mark for working with me on this issue!
I am taking your recommendation to create a   webapps-javaee directory and 
place my Tomcat 9 running war file into
that dir so that Tomcat does the compile correctly.

Only problem is that now I cannot figure out what is the correct URL path to my 
servlet!

When I place the .war, the old way with the .war  being in  
webapps/transaction,my tomcat cat log says...

Deploying web application directory [C:\apache-tomcat-9.0.73\webapps\transaction
And I see my application at 
C:\apache-tomcat-9.0.73\webapps\transaction\ROOT##0001

And I can hit my servlet via...

http://localhost:8588/XmlRpc

BUT when I place my .war in webapps-javaee\transaction the tomcat cat log 
says..

Deploying web application directory 
[C:\apache-tomcat-10.1.18\webapps-javaee\transaction\transaction

And I cannot hit either..

http://localhost:8588/XmlRpc 
or
http://localhost:8588/transaction/XmlRpc


The creation of the 
C:\apache-tomcat-10.1.18\webapps-javaee\transaction\transaction  directory is 
baffling me
See attached file

I expect only to see the creation of a 
C:\apache-tomcat-10.1.18\webapps-javaee\transaction\ROOT##0001 directory.
That is where I believe my application to be

Here is how I have my context defined in server.xml..



Is my server.xml wrong?
When I place my .war in   webapps-javaee\transaction   dir?

Confirmed this is user error. There is no bug in the migration tool.

Steps to demonstrate this:

- Create new, blank Eclipse dynamic web project
- Add provided servlet code
- Add required libraries
- Remove referenced to internal logging code
- Add web.xml with basic mapping to "/test"
- Export WAR file
- Deploy to Tomcat
- Start Tomcat
- Request servlet

Servlet loads and then reports an exception during init. That is fine.
It proves that the servlet was loaded which is all we care about at this point.

- Use migration tool to migrate WAR
- Deploy migrated WAR to Tomcat 10.1.x
- Start Tomcat
- Request servlet

Servlet loads and then reports an exception during init. Again, this is fine as 
it proves that the Servlet has been converted correctly and can be loaded by 
Tomcat 10.1.x.

Best guess, the Eclipse project isn't configured correctly to compile the web 
application for Tomcat 10.1.x.

At this point the simplest solution is likely to be:

- take the WAR file that works on Tomcat 9
- drop in webapps-javaee in Tomcat 10 and let Tomcat convert it
   automatically

RE: [EXT]Re: [EXT]Re: jakartaee-migration-1.0.7 migration tool failure

[Rick Noel]

No I cannot compile from command line.

But I do not really care how eclipse compiles my class anyway.
All I know is that eclipse compiles the class without errors. Using the jars I 
tell it to. (all the jars run through the migration tool)
But Tomcat 10 can not compile the class using those same migrated jar files.

And my class has no use of javax.server  classes in it.
All the javax.server classes are only in the third part jar files which are 
supposed to have been converted to use  jakarta.server classes

Is this not a bug with Tomcat migration tool?

Again here is my class that does not compile on Tomcat 10...
It has no reference to  javax.server

I built  my app in Eclipse  and the build path is set to use the migrated jar.
It compiles without error on Eclipse and using the migrated jar.  I have that 
same migrated jar in the Tomcat lib
But when tomcat 10 compiles it does not compile

I have also used the migration tool on my .war that runs in Tomcat 9 and that 
war still fails with same compile error.

So to summarize. the migration tool fails to convert third party jar 
xmlrpc-server3.1.3.jar
And it also fails when I use it on my .war ran through the migration tool.

Then you need to fix your build system that is compiling your code against the 
original xmlrpc-server3.1.3.jar rather than the migrated version.

> Is it not the third part jar that needs to stop using javax.server ?

No. It is the compiled form of your code that has the issue.

When you compile your class it retains a reference to the version of 
org.apache.xmlrpc.webserver.XmlRpcServlet that it was compiled against.
You can't just swap the xmlrpc-server3.1.3.jar at runtime. You have to use the 
migrated JAR at compile time as well.

My code uses no javax.server  code other that what is in the third party jar.

The bug is your code. You need up update RVXmlRpcServlet to use 
jakarta.servlet.Servlet rather than javax.servlet.Servlet

Ditto for any other Java EE classes you have referenced in your code.

If you want your application to work with Tomcat 9 and Tomcat 10 I suggest you:

- write it for Tomcat 9
- package it as a WAR file
- process the entire WAR file with the migration tool
- use original WAR file with Tomcat 9 and the migrated WAR file with
   Tomcat 10+

My class is RVXmlRpcServlet and below is the compile error that happens when I

Please provide details of the compilation errors that you see.

That seems ... unlikely.

I'd be surprised if the migration tool didn't process a JAR that old correctly.

jakartaee-migration-1.0.7 migration tool failure

[Rick Noel]

Our application uses classes in this jar xmlrpc-server3.1.3.jar .(it is the 
latest version)

We are trying to migrate to Tomcat 10 but that  jar uses the   javax.server. 
package classes instead of the needed  jakarta.server. pacakage.


I have tried running this jar trough the latest Tomcat 10 migration tool 
(jakartaee-migration-1.0.7) which is suppose to alter the jar to make all 
classes use  jakarta.server.  classes

but the tool is not fully converting all the classes,  since I still get 
compile errors at run time.


I think in addition to not using  javax.server.  the jar should use this class

java.net.URI  instead of   java.net.URL


anyone have ideas on how to make xmlrpc-server3.1.3.jar  tomcat 10 compliant?

BTW the jar in question has classes in this package
org.apache.xmlrpc.
