Tomcat + APR non-root on linux: Socket bind failed: [98] Address already in use

[Ken Johanson]

Hi everyone,

Trying to run Tomcat Tomcat/6.0.18 + apr-1.3.8.tar.gz, I get a:

Oct 15, 2009 12:11:20 AM org.apache.coyote.http11.Http11AprProtocol start
SEVERE: Error starting endpoint
java.lang.Exception: Socket bind failed: [98] Address already in use
at 
org.apache.tomcat.util.net.AprEndpoint.init(AprEndpoint.java:612)

..
(no listener is actually running on 98; this is just generic Sun msg 
when not allowed to bind to prv'd port)


I am also running Tomcat as a non-root user, e.g:
daemon --user www $CATALINA_HOME/bin/startup.sh
and also tried jsvc...

same problem.

Is there a configuration to change the port that APR uses from 98 to a 
non-privileged (1024) one?


TIA,
Ken

You cannot use port  1024 as non-root. Use apache and AJP to connect 
tomcat running on eg. 8080. Regards

Thank you Jan. Actually I tried to show that I already knew that 1024 
wont bind, if you noticed. That is the crux of the problem. I need a way 
to config APR to *not* use the tcp/98 default. And the whole point of 
using APR is to *not* use httpd and ajp...


Thanks again,
Ken

98 is the errno (EADDRINUSE), not the port.  The error message doesn't list
which port failed.

APR doesn't use any ports other than the ones you configure in your
connectors.  Something is holding onto one of the ports you want.  Check
what ports Tomcat wants, and check there isn't another process running on
the box that is using one of them - it might even be an old Tomcat.  Don't
forget to check the shutdown port (8005 by default), although from the stack
trace it looks like the problem port is a connector, not the shutdown port.

I'm using 32-bit JVM (JDK 1.5.0_21) on 64-bit Windows.

Form Tomcat 5.5.28 changelog: Add the 64-bit windows service binaries
to the distribution and get the Windows installer to automatically
select the correct one for the current platform. (markt/kkolinko), so
I cannot find different service installer for 32-bit - there is only
one Windows installer
(http://tomcat.apache.org/download-55.cgi#5.5.28)

When I install Tomcat 5.5.28 on 64-bit Windows + 32-bit JVM I get
64-bit service version of Tomcat. There is a note that if I have a
64-bit operation system, I must specify 64-bit JRE during Tomcat
installation, but I strongly needs in 32-bit JRE and 32-bit Tomcat
service on 64-bit Windows.

Is it feasible to install 32-bit version of Tomcat on 64-bit Windows +
32-bit JVM?

Re: Problem in configuring tomcat for PKCS 11 for HSM

[Israr Ahmed]

Hi,

I've successfully configured apache-tomcat-6.0.18 with JRE 1.6.0_13 for
PKCS11 with keystore on smart card token but failed to use keystore on HSM
which is in my case Eracom PSO:PL50

I've statically add a provider in java.security file 

security.provider.10=sun.security.pkcs11.SunPKCS11
${java.home}/lib/security/pkcs11.cfg

pkcs11.cfg contains the following entries:

name = tokenName e.g. Token1
library = mypkcs11.dll
slot = 0

and my connector settings are:

Connector port=4445 
   minSpareThreads=25 
   maxThreads=150 
   maxSpareThreads=75
   maxHttpHeaderSize=8192
   enableLookups=false 
   disableUploadTimeout=true
   acceptCount=100 
   connectionTimeout=6
   SSLEnabled=true   
   scheme=https 
   secure=true
   clientAuth=true 
   sslProtocol=TLS
   keystoreType=PKCS11
   keystorePass=password  
   ciphers=SSL_RSA_WITH_RC4_128_SHA/

These settings work fine with PKCS11 smart card token but when i try to use
these settings for network HSM which is Eracom PSO:PL50, i'm unable to
communicate with network HSM, I applied the changes against library and name
properties in pkcs11.cfg for HSM.

I've also configured my connector like:

Connector port=443 protocol=HTTP/1.1 SSLEnabled=true
   maxThreads=150 scheme=https secure=true
   clientAuth=false sslProtocol=TLS
protocols=TLSv1 
   algorithm=SunX509  
   keystore=NONE keystoreType=PKCS11
keystoreProvider=SunPKCS11-HSMName keystorePass=X
/

but still no progress.

I'm unable to find out the solution. I'll be thankful to you if you figure
out me the problematic area or suggest any solution to resolve this problem.

Thanks in advance.

Regards,

Israr Ahmed

 Subject: Re: How to install Tomcat 5.5.28 32-bit version on Windows 64-
 bit version?
 
 I strongly needs in 32-bit JRE and 32-bit Tomcat
 service on 64-bit Windows.

Could you please tell us why?  I can't imagine any reason one would want a 
32-bit JVM these days, except for JNI compatibility, which is not an issue with 
Tomcat.  Note that you can have both 32- and 64-bit JVMs installed at the same 
time.

 Is it feasible to install 32-bit version of Tomcat on 64-bit Windows +
 32-bit JVM?

Tomcat itself is pure Java, so it's only the service wrapper that has to be the 
same mode as the JVM being used.  You can get the 32-bit version here:
http://svn.apache.org/repos/asf/tomcat/tc6.0.x/trunk/res/procrun/

Hi,

Am Mittwoch, 14. Oktober 2009 schrieb Christopher Schultz:

 Although those threads say runnable, they're really blocked at the OS
 level waiting to receive data from the mod_jk connector. These threads
 are actually idle, waiting for requests from httpd to come through the
 pipe.

 You can probably confirm this by checking with 'top' to see that Tomcat
 isn't using any CPU time, because it's just waiting.

exactly. That's what I meant with waiting for input from the Apache servers.
Thanks for confirming this.

 Is it feasible to remove httpd from the equation? Tomcat 5.5 can easily
 compete with httpd for static file delivery if that's all your using it
 for.

Not really. We're relying on mod_jk for load-balancing with sticky
sessions, and for SSL termination. Getting rid of the Apaches would be
a major PITA.

 If you could post your httpd configuration for your worker/prefork stuff

Tomcat restart not killing session

[sharda k]

I was under the impression that restarting webserver would kill all user
sessions. But with my tomcat install, restarting Tomcat does not kill user
sessions. I am still able to continue with the initially started sessions.
Is this a typical tomcat behaviour or a bug?

I have Tomcat 5.5 running on Windows Vista.

Can anyone please help?

Thanks,
Sharda

Snip-

When I look at the resources that Tomcat recognizes through the manager 
app, I see the following:

OK - Listed global resources of all types
mail/Session:javax.mail.Session
UserDatabase:org.apache.catalina.users.MemoryUserDatabase



So it looks like its there.  How do I expose this to my application?  I'm 
sure I'm missing something obvious, but I can't seem to figure it out.  

Thank you!

All that looks okay to me, though as Mark and Tsirkin suggest, you might

connection timeout (which forces mod_jk connections to be destroyed
after a certain amount of time, just to clean things up).

Check out the template capabilities of later mod_jks. You might save

Re: Shared email resource

[Curtis Garman]

I've only every declared in in META-INF/context.xml ...but I've also
experienced another problem before that you may be having and that is
truncating the resource name...it will take your valid name and chop
off part of it (seems to truncate at / ) and then complain that it
couldn't find the resource. The reason you may be having this issue is
I noticed in your log error it says

javax.naming.NameNotFoundException: Name mail is not bound in this Context

Based on my experience using it I would expected to see ResourceLink

javax.naming.NameNotFoundException: Name mail/Session is not bound in
this Context

If you are still having the problem after moving your to the
context.xml file, you may want to try a name without slashes to see.
We are running tomcat 5.5.25 and this version seems to recognize names
with slashes but we upgraded from a version (don't know the number)
that I never could get resource links with slashes in them to work.

RE: Windows 2008 Server (x64) IIS7 to Tomcat 6.0 32-bit with Java 32-bit isapi_redirect 1.2.28 connector problem

[George Sexton]

Why would you use the 32 bit ISAPI filter? You should use the 64bit ISAPI
filter.

If you're running IIS7 in 32 bit mode, THEN you should use 32 bit filter. If
you do that, make sure the registry entries for configuration are in the
WOW64 registry node.

Re: how to replace apache's mod_alias

[Dennis Christopher]

Thanks for the reply Chris.

what I want to do:

I am running Tomcat as a standalone server on OSX. My application had  
been previously set up with apache serving in front of Tomcat.


My application is a context element '/myapp' accessed via server  
address/myapp.


Within the app's jsps are references to files in a folder 'myapp-web'  
whose real location on the server file system

is outside the tomcat tree.

I am unclear whether these references are actually supported in the  
previous version via mod_alias or a symbolic link
created for /library/webserver/documents. Tomcat the definitive guide  
says that if allowLinking
in the myapp context is true that it should work, but so far it has  
not worked for me.

 Within the app's jsps are references to files in a folder 'myapp-web'
 whose real location on the server file system
 is outside the tomcat tree.

So, the URLs for these resources are something like
http://host/myapp-web/path/to/file? Are they all rooted in the same place?

If so, you can basically create a dummy webapp that contains nothing but
your files, served out of the location of your choice.

Create a file under CATALINA_BASE/conf/[service]/[host]/myapp-web.xml
that contains the following:

Context appBase=/library/webserver/documents /

This will deploy a new web application (into /myapp-web) that serves
static documents from /library/webserver/documents. This is the
equivalent of Apache httpd's:

Alias /myapp-web /library/webserver/documents

It probably seems a little heavy-handed, but it's because app servers
are app-centric, not file/directory centric.

Hope that helps,

Chris,

the user accesses my jsps via http://host/my-app.

The jsps include references of the form below, as request dumper valve  
tells me:


/myapp-web/styles/images/mylogo.jsp

where myapp-web is a directory elsewhere on the system.

so the full path reference style is never done as such.

http://host/myapp-web/path/to/file? Are they all rooted in the same  
place?


If so, you can basically create a dummy webapp that contains nothing  
but

your files, served out of the location of your choice.

Create a file under CATALINA_BASE/conf/[service]/[host]/myapp-web.xml
that contains the following:

Context appBase=/library/webserver/documents /

This will deploy a new web application (into /myapp-web) that serves
static documents from /library/webserver/documents. This is the
equivalent of Apache httpd's:

Alias /myapp-web /library/webserver/documents

It probably seems a little heavy-handed, but it's because app servers
are app-centric, not file/directory centric.

Hope that helps,

catalina - when to use start and run

[Anand HS]

Hi, I use tomcat 6.0.16 and when evaluating different start up options , I
came across the fact that you can start tomcat by either catalina start or
catalina run.
using start spawned the server start up in a new console where as run
started in the same console.

Other than this is there any obvious difference in using one or the other. ?
Primarily, I want to know when to go for which one.

thanks,
Anand

I've only every declared in in META-INF/context.xml

It's fine to define Resource completely in context.xml.
But if one uses GlobalNamingResources (as OP does) he has to declare 
mapping in context.xml as I described.

Anyway, it works for me all the times :-)

Of course, in Java code one has to lookup using full path, not just 
mail/Session, so:


new InitialContext().lookup(java:comp/env/mail/Session);

So, I have on my Tomcat 6.0:

conf/server.xml:

GlobalNamingResources
 Resource name=jdbc/db auth=Container
   type=javax.sql.DataSource
   driverClassName=org.postgresql.Driver
   ...
   /

application's META-INF/context.xml:

Context
   ResourceLink name=jdbc/db
   global=jdbc/db
   type=javax.sql.DataSource /
/Context

application's WEB-INF/web.xml:

   resource-ref
   res-ref-namejdbc/db/res-ref-name
   res-typejavax.sql.DataSource/res-type
   res-authContainer/res-auth
   /resource-ref


And I use new InitialContext().lookup(java:comp/env/jdbc/db); to 
retrieve DataSource.


Hope that helps.

Re: how to replace apache's mod_alias

[Dennis Christopher]

Hmm. I thought that correction would make it work, but still no go.

I don't have any structure under conf, and usually add contexts in  
server.xml . I tried this first, giving path=/myapp-web.
But this didnt work. It seems by the logic of what we are trying, i.e.  
making the docBase = /library/webserver/documents', that my images,  
e.g won't be reachable unless the symbolic link in the docBase is  
valid as well. It looks like it is, but just in case, I tried putting  
the absolute path into the docBase as well. No go either.


Next, and maybe I didnt follow directions properly,  I added the  
directory conf/localhost

which then contained myapp-web.xml with the (pathless) context below.

Tried this also with the absolute path and still no joy.

Re: DBCP woes (running out of cursors).

[Bill Davidson]

Christopher Schultz wrote:
Is it possible that your server just doesn't want to allocate 245 * 4
cursors, and that you are just hitting that barrier?

cursor != connection

Oracle is set up to allow up to 300 cursors per session (connection).
I could up that limit, but it probably won't fix the problem, as these
things seem to just keep accumulating.

I though you said that after a connection was checked-out for 120
seconds, it was forcibly closed by the connection pool.

Only when it is sent back to the pool by the servlet.  The pool manager
doesn't have a background thread looking for old connections to kill.
It's not a work around for connection leaks.  Apparently it's a work
around for cursor leaks.

Oh, so this query is intended to find out what is happening on the
server side, so you can see what cursors are open and what their queries
are. I thought you meant that a query such as this was being executed
from your webapp.

Correct.  Sorry if I didn't make that clear.  Those queries are not in
my webapp.  They are only used to help track down lingering cursors.
For people not familiar with Oracle, special characters like '$' in FROM
clauses are usually an indication of something being in Oracle's data
dictionary which keeps track of everything in Oracle.  The other one
in that query was v$session which keeps track of session information.
A session, in this context, is a connection.

Do some of those methods have multiple queries being executed? If so,
it's possible that one statement remains open while the second one is
closed. For example:

A very small number do, but the vast overwhelming majority do not.
I'm finding these lingering cursors on all sorts of things.  On the ones
that do, they are all still closed.

This is perfect. I noticed that I don't see a conn.close in there (which
is probably appropriate, given that the Connection object is a parameter
to the method). I assume you have similar finally blocks in calling
methods, right?

Correct.  I'm not seeing anything resembling a connection leak problem.
This is strictly a cursor problem.

The eviction run will only to remove connections from the pool: it won't
fix any resource allocation problems. Your webapp and server ought to be
able to tolerate all connections being open and active at once (so, a
full 245 connections in each webapp instance, and 980 connections on the
server).

The Oracle instance is set up to handle 1000 connections.  Tomcat has
maxThreads=240, just because I'm paranoid and want to leave a little slop
factor.  I shouldn't ever see more than 240 actual connections per server.

The only thing the eviction will really help with is reducing the memory
being used on both the client and server. I suppose that calling a
true close() on the connection might clean-up any sloppiness going on
in the client OR the server, and thus might solve your problem, but I
believe it will be merely hiding the symptom, not actually solving the
underlying problem.

I suspect that you are correct.  I'm baffled as to why I have old cursors
lying around.  The close call on the statements has to happen.

Do you have access to an Oracle DBA? They may be able to help uncover
the implications of some of the queries being run... it's possible that
cursors are being allocated that you didn't expect, or that aren't being
closed for /other/ reasons.

The Oracle DBA that I have access to doesn't know much about Java/JDBC
which is why I was hoping I could find some Oracle expertise in the
commons or tomcat lists.

are you running as a Transaction?

In some cases, but a lot of these lingering cursors are on very simple
queries, with no insert/update/delete involved.  As I said before,
I'm finding lingering cursors on things as simple as SELECT * FROM
some_table WHERE id = ?.

That does make me wonder though if there are Connection's getting sent
back to the pool that had a pending transaction without a commit/rollback
and if that could be making any cursors on that connection after that
linger?  It might explain the randomness of the queries showing up in
the list.  It also gives me a question I can send to my Java-challenged
Oracle DBA.  Thanks for the idea.

Fw: Re: Metro/JAXWS and network packets...

[Tony Anecito]

Hi Wireshark group.

I narrowed down the redundant packets last night/this morning. I have notified 
the Sun group about the issue and am still looking at it closer.

Thanks for the help this has been a huge issue for me and now for Sun perhaps.

Best Regards,
-Tony

 Hi All,
 
 I created a simple java program that created a URL object
 and sent a http request to a Tomcat server for a small less
 than 1500 byte file and two packets were set to/from the
 Tomcat Server.
 When I send the same request via FireFox only one packet is
 sent/recieved.
 So this is not a Metro issue but a core issue with the jre
 and TCP.
 
 This issue may only be with data less than 1500 bytes and
 TCP.
 
 Regards,
 -Tony

  I noticed if I send a request via

 bytes
  (Maximm Segment Size or MTU Maximum Transport Unit
 size) the
  data gets sent/received in two packets. If I use

  Any idea why this is happening? It seems to double
 the
  number of packets for communication. The data is not
  duplicated in the two packets but instead is
 fragmented.
  
  I am using a Java Client using jre 1.6.0_16 and the
 Tomcat

 1.6.0_16.
  All are Windows based OS.

Can a JNDI resource be in a webapp's lib folder

[Ziggy]

I am trying to set up a JNDI resource of an Oracle database connection. I
have set the connection details in my application's context file in
$CATALINA_BASE/webapps/myapp/META-INF/context.xml

I put the jdbc driver in $CATALINA_BASE/common/lib and everything works
fine. The problem is i dont want to put the jdbc driver in that directory. I
would like to put it in $CATALINA_BASE/webapps/myapp/WEB-INF/lib

I have read about this a bit and i think that all JNDI resources must be in
$CATALINA_HOME/common/lib which explains why If i put the driver in the
application's lib folder it cant access it because the common class loader
wouldnt konw of the libraries in the applicatoins lib folders..

The tomcat installation only runs this one application. I  would like to be
able to move the application's war file (which will include all libraries in
the WEB-INF/lib folder) around to other tomcat instances if i need to
without having to worry about moving libraries as well.

Its a bit weird that i configure the JNDI resource in the application's
context file but the library that the context file is refering to is to be
kept outside of the application.
is there a way i can use the JNDI resource but have the jdbc driver in the
application's WEB-INF/lib directory?


Thanks in advance.

Redeploy problem in 6.0.20

[Andrew Morgan]

I recently upgraded from Tomcat 6.0.18 to 6.0.20 (using jdk1.6.0_14 on 
Solaris 10).  I have a webapp that stores its database configuration in 
the context xml file (/private/tomcat/conf/Catalina/localhost/devl.xml). 
Periodically, I must update the context xml file when the database 
password has been changed.


When I was running 6.0.18 and earlier, a few seconds after I modified the 
context xml file, Tomcat would redeploy the webapp and log the following:


Oct 15, 2009 12:27:08 PM org.apache.catalina.startup.HostConfig checkResources
INFO: Undeploying context [/devl]

and the webapp would continue running.

After I upgraded to 6.0.20, modifying the context xml file triggers a 
redeploy that fails with the following logs:


Oct 15, 2009 1:10:50 PM org.apache.catalina.startup.HostConfig checkResources

 cursor != connection

Right... but presumably your code is doing something useful with that
connection, rather than simply fetching it from the pool and then
discarding it. IIRC, all SELECT queries allocate a cursor. Others may as
well.

 Oracle is set up to allow up to 300 cursors per session (connection).
 I could up that limit, but it probably won't fix the problem, as these
 things seem to just keep accumulating.

Agreed. But, I wonder if there's a max cursors globally or something
like that, so that when you have all those connections going at once,
their sum total cursors exceeds that limit?

When this happens, does Tomcat continue running otherwise unscathed? Or,
do you get an avalanche of exceptions after the first one occurs. What
about on the other members of the cluster (just a descriptive term, not
a technical one)?

I though you said that after a connection was checked-out for 120
seconds, it was forcibly closed by the connection pool.
 
 Only when it is sent back to the pool by the servlet.  The pool manager
 doesn't have a background thread looking for old connections to kill.
 It's not a work around for connection leaks.  Apparently it's a work
 around for cursor leaks.

Hah, okay. Well, it doesn't look like commons-dbcp has a similar
configuration option; you can only evict connections that have been
sitting idle, not those that have simply lived too long. Perhaps the
commons-dbcp folks have some ideas.

Oh, so this query is intended to find out what is happening on the
server side, so you can see what cursors are open and what their queries
are. I thought you meant that a query such as this was being executed
from your webapp.
 
 Correct.  Sorry if I didn't make that clear.  Those queries are not in
 my webapp.  They are only used to help track down lingering cursors.
 For people not familiar with Oracle, special characters like '$' in FROM
 clauses are usually an indication of something being in Oracle's data
 dictionary which keeps track of everything in Oracle.  The other one
 in that query was v$session which keeps track of session information.
 A session, in this context, is a connection.

Gotcha. I wonder if somehow your app-based queries are allocating
cursors and never freeing them. Simple SELECT queries (or even complex
ones) shouldn't really be allocating cursors that aren't freed when you
call ResultSet.close or Statement.close (whichever actually kills them,
I'm not sure). Also, closing a pooled connection should call
setAutoCommit(true) (this is the default setting for autocommit) which
will commit any in-progress transactions lingering, which I would
imagine results in all cursors being closed as well. I must admit, I'm
at the limit of my (quite limited) Oracle knowledge at this point. Got a
DBA handy?

The eviction run will only to remove connections from the pool: it won't
fix any resource allocation problems. Your webapp and server ought to be
able to tolerate all connections being open and active at once (so, a
full 245 connections in each webapp instance, and 980 connections on the
server).
 
 The Oracle instance is set up to handle 1000 connections.  Tomcat has
 maxThreads=240, just because I'm paranoid and want to leave a little slop
 factor.  I shouldn't ever see more than 240 actual connections per server.

Agreed.

 I suspect that you are correct.  I'm baffled as to why I have old cursors
 lying around.  The close call on the statements has to happen.

Yeah, I agree. The only thing I can think of is that you are pooling
prepared statements. If you have more than 300 different queries in your
webapp (not at all a stretch IMO), and they are all being pooled, it's
possible that each one of those cached prepared statements consumes a
cursor. In that case, you'll easily consume your cursor allocation per
request. I'm just grasping at straws, now.

What happens, other than an awful slowdown, if you disable statement
pooling?

Do you have access to an Oracle DBA? They may be able to help uncover
the implications of some of the queries being run... it's possible that
cursors are being allocated that you didn't expect, or that aren't being
closed for /other/ reasons.
 
 The Oracle DBA that I have access to doesn't know much about Java/JDBC
 which is why I was hoping I could find some Oracle expertise in the
 commons or tomcat lists.

Yeah, see what the commons-dbcp list has to say. Things are ... pretty
slow on the commons-user list, so you may have to wait a bit for a
reply. You could also ask on some Java-oriented Oracle forums.
Definitely post back if you find a satisfactory explanation so everyone
can ready about your new-found sage advice ;)

Probably not. DBCP calls setAutoCommit(true) by default in order to

any in-progress transactions lingering around.

If you set autoCommit=false in your DBCP configuration, that might

 It might explain the randomness of the queries showing up in

I believe this is correct: the JNDI resources for a webapp are

this reason, you must place your JDBC drivers (and anything else

CATALINA_BASE/lib (on TC 6.0), or, define some other ClassLoader that is

I'm a little confused about auto-commit.  I don't want my transactions
auto-committed.  Sometimes there's a need for a rollback of an entire
transaction.  To my thinking, auto-commit implies that you don't have
true transactions.

The transactions in the app are a lot more complex, and a transaction
can hold onto a connection for quite a while as a user is editing things.
The queries themselves have the same try-catch-finally situation but
there can be quite a few different calls on that connection for one
transaction.

But what is the likelihood of SELECT * FROM foo WHERE foo.id=?
appearing in a transaction?

Very low.  The scenario I was describing was:

1. Thread 1 returns a connection with an uncommitted transaction to the 
pool.

2. Thread 2 gets the same connection from the pool and does a query on it
3. The query from Thread 2, unrelated Thread 1, ends up in cursor limbo
  because of the uncommitted transaction on the connection.

I don't know that this is happening in the app, and it's going to be very
difficult to find it if it is.  I don't even know that this scenario 
could cause this

cursor limbo.  It's just a hypothesis which is hard to test.

Not sure if that's feasible without spec changes.  The JNDI registry is for the

classloader, they would be visible to but not usable by other webapps.  There 
may be ways to construct local (per-webapp) JNDI domains, but I don't think 
there's anything like that in the spec.

Is there a configuration to change the port that APR uses from 98 to a
non-privileged (1024) one?



APR doesn't use any ports other than the ones you configure in your
connectors.  Something is holding onto one of the ports you want.  Check
what ports Tomcat wants, and check there isn't another process running on
the box that is using one of them - it might even be an old Tomcat.  Don't
forget to check the shutdown port (8005 by default), although from the stack
trace it looks like the problem port is a connector, not the shutdown port.



PS - Connector.xml excerpts:
   Connector
  protocol=org.apache.coyote.http11.Http11AprProtocol
  port=8443
  enableLookups=false
  SSLEnabled=true
  scheme=https
  secure=true
  SSLCertificateFile=${catalina.base}/conf/cert.crt
  SSLCertificateKeyFile=${catalina.base}/conf/cert.key
  disableUploadTimeout=true
   /
   Listener className=org.apache.catalina.core.AprLifecycleListener
SSLEngine=on /



Any other connectors defined?

Thank you Peter you are correct! The 98 being mentioned by itself is 
very misleading, at least for a lay person like myself :)


It was indeed the normal listeners (8080 and 8443 in my case). I 
COMPLETELY took for granted that my init script was handing the 
shutdown... it is not. Using APR and an init-script* (or jsvc) that 
worked just fine for JIO and NIO, the server does not shutdown for APR. 
I have to `ps` for the java proc then send a kill signal to it. I'm not 
sure why but it may be related to bad cleanup code for the 
following, *newly observed problem*.


After doing a kill, then startup I now get:

java.lang.Exception: Invalid Server SSL Protocol
at org.apache.tomcat.jni.SSLContext.make(Native Method)

org.apache.tomcat.util.net.AprEndpoint.init(AprEndpoint.java:693)

SEVERE: Catalina.start
LifecycleException:  Protocol handler initialization failed: 
java.lang.Exception: Invalid Server SSL Protocol

at
..

But I can't see where I'm deviating from docs with:
Connector
port=8443
enableLookups=false
SSLEnabled=true scheme=https secure=true
SSLCertificateFile=${catalina.base}/conf/cert.pem
SSLCertificateKeyFile=${catalina.base}/conf/key.pem
disableUploadTimeout=true
SSLVerifyClient=optional
sslProtocol=TLS
/

BTW I'm now tryng recent apache-tomcat-6.0.20 and rebuilt 
tomcat-native-1.1.16.


Any insight would be immensely appreciated!

Best regards,
-Ken

Presumably the shutdown failure is caused by this NPE interrupting the call:

Tomcat works fine on deployed machine, but not on others machines in network

[Avijit Dutta]

We have installed tomcat in a linux machine, and when we invoke http://linux
machine ip:8080/ from that linux machine, it is showing properly.
But, when we try to access the same URL from another machine in the same
LAN, then nothing is coming up.
Please help.
 
The 2nd machine is able to ping the linux machine's IP.
Also. firewall is disabled.
 
~Thanks

Avijit Dutta
