RE: Problem with file upload corruption.

[Richard Mixon (qwest)]

OK, my goof. In my frustration and hurry I did not read the RFC well
enough. After re-reading the RFC yet one more time, it finally became
clear. In case it helps anyone else, I'm posting what I learned here. 

Basically the browser is allowed/expected to set the encoding type.
Under section 3.3 of RFC 1867:

  3.3 use of multipart/form-data

 ... Each part should be labelled with an appropriate
 content-type if the media type is known (e.g., inferred from the
file
 extension or operating system typing information) or as
 application/octet-stream. 
 ...

I kept expecting there to be some way to designate the file as either
binary (don't change a thing, just upload it) or text (handle CRLF's and
character set translation) - much like one does with an FTP tranfer.

So I guess the best answer to my original dilema is to write a utility
method/filter that inspects the uploaded HTML file for invalid
characters and notifies the user if any are found.

Hope this helps someone else - Richard

Sorry to kick this up. I know it’s a slightly obscure topic, and I'm

I just tried using the Jakarta Commons File Upload instead of the

a Windows machine all occurrences of 0x0D0A are converted to 0x0A. So

We have a JSP/servlet combo that uses the OReilly MultiPartRequest to
upload a users HTML template for our application. Invariably they end up
with some unusual characters in their template - sometimes from pasting
in text from MS Word or other similar application.

For some reason a single character (e.g. x092 a "right single quotation
mark") is turned into multiple special characters after it is uploaded.
When we download it  we use

Here is an example - the right single quotation marka backward single

I have read the file upload RFC 1867 until I'm blue in the face, and
Googled on and off the servlet.com site. There were reported binary
upload problems using the warp connector to connect Tomcat 4.0 and

Any ideas or suggestion are appreciated.

RE: configuration files for war deployments

[Richard Mixon (qwest)]

Patrick,

Sorry for the late response. You have received quite a few ideas, but I
did not see one quite like what we do.

We use the deployer utility to deploy our application and have
customized (just added a task actually) the build.xml file to make
system-specific changes to our war and then re-jar/war it.

In case you are not familiar with the tomcat deployer it is a companion
download. For example if you downloaded jakarta-tomcat-5.5.9.zip, there
is a corresponding jakarta-tomcat-5.5.9-deployer.zip to download. 

The deployer is really just a few jar files with tomcat-specific ant
tasks, a build.xml and and example deployer.properties file.

The ant build file has targets to compile (including JSPs), undeploy and
deploy an application to one or more tomcats. The deployer.properties
file controls this if the defaults are not good.

We just added a coupld of ant replace and copy tasks that modify various
properties and xml files for the target host.

It means that on each host that needs specific configuration you:
- explode the war file
- run "ant compile undeploy deploy"
You now have a customized web application installed.

Hope it helps - Richard

Subject: configuration files for war deployments

hi All,

If I were to deploy my application as a .war file, where do I place the
.properties configuration files?  I know there's the option of
auto-expanding the war file at deployment, but is there a way to keep
the war file unexpanded and provide an external .properties file for the
web app to read from?

Many thanks

RE: Array as context parameter

[Richard Mixon (qwest)]

Well,

Understand that once you enter the domain of having someone edit an XML
file, you are already into "error prone" territory.

You might consider changing the parameter to specify a file name. The
specified file could be formatted anyway you liked, but probably with
one value on each line of the file. Just have context listener read this
file at startup and place the array in the context.

Hope this helps - Richard

That sounds better. It's surely more user friendly. But the chance of an
error during entering coma-separated values is bigger. It's easy to
forget about coma or place dot. Are there any other solutions?

JspC compile exception in tomcat-deployer 5.5.10

[Richard Mixon (qwest)]

Hello,
 
I am using the 
jakarta-tomcat-5.5.10-deployer to deploy my customized war file to tomcat. When 
I have it do the "compile" target so it pre-compiles the JSP's I get 
the exception below (its sort of long). I've got the source and can see 
that it is happening as it processes the JSPs. But it gives no clue as to 
which JSP is causing the problem.
 
Is there a way to turn on a 
trace that would list each file as it is processed? I've also looked in the output directory - 
but there are not class files at all. And the generated_web.xml is completely 
empty at this point.
 
Here is how I've got the 
jasper2 task defined in my build.xml:     
uriroot="${webapp.path}" 
 
webXmlFragment="${webapp.path}/WEB-INF/generated_web.xml" 
addWebXmlMappings="true" 
outputDir="${webapp.path}/WEB-INF/classes" /> 
 
Notice that I turned 
validateXml to false - otherwise I get the following 
message:
    [jasper2] 
org.xml.sax.SAXParseException: Document is invalid: no grammar 
found.
I have compared and compared my 
web.xml to the spec and it seems to be OK. It complains about position 9 in the 
3rd line. Line 3 follows, position 9 is the start of the "xmlns=" 
attribute:
http://java.sun.com/xml/ns/j2ee"    
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee    
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"    
version="2.4">... which appears to be fine.
 
Any ideas or help is 
appreciated. I have tried this a few months back in 5.5.7 but got the same 
results (worked fine in 5.0.19). I imagine its a problem either in one of my 
JSPs or in the web.xml - but cannot figure it out.
 
Thanks in advance for any 
ideas.

Richard

Tomcat 5.5.10 jasper2 fails in deployer build.xml

[Richard Mixon (qwest)]

I think I found a problem with the jakarta-tomcat-5.5.10-deployer
package. When I run the compile task I get the following error:
  BUILD FAILED
  C:\jakarta-tomcat-5.5.10-deployer\build.xml:49: Could not create task
or type of type: jasper2.

  Ant could not find the task or a class this task relies upon.

Is this a known bug? I did not find it in Bugzilla, but the search
interface is a bit strange to me.

I looked in the c:\jakarta-tomcat-5.5.10-deployer\lib\catalina-ant.jar
file and discovered that the catalina.tasks file is missing a definition
for the jasper2 task like is found in
c:\jakarta-tomcat-5.5.9-deployer\lib\catalina-ant.jar. Here are the
contents of the 5.5.10 catalina.tasks file:

# Pure catalina tasks

Here are the contents of the 5.5.9 catalina.tasks file:

jkstatus=org.apache.catalina.ant.JKStatusUpdateTask

# Jasper tasks

I added the "jasper2=org.apache.jasper.JspC" line and its seems to work
fine.

Hi Edgar,

Thanks for the reply.
But I am using Tomcat 4.1.29 and I tried this option (I mean,
pathname="" in Manager element of server.xml) in Tomcat 4.1.29, which is
not successful. Is there any way to turn off session persistence in
Tomcat 4.1 itself or I need to upgrade to Tomcat 5.0.

In order to avoid the exception we have to make all the objects that is
put in session to be serializable, right no?.

I am using struts framework. So by default all form beans are
serializable and all primitive data types are also serializable.


Why Tomcat complains about CoyoteRequestFacade is not serializable?


Please clarify my doubts.

RE: question about deployment (including executables in war)

[Richard Mixon (qwest)]

Murad,

I would not copy the files - but just change the permissions. No restart
should be necessary that way - unless I'm missing something.

However to answer your question, using the build.xml in
jakarta-tomcat-5.5.9-deployer, I usually use the following command to
restart the application:
  ant stop start

It works for me. That said, I have seen cases where after I deploy and
app and then do a start I get complaints ... Doing something like:
  Ant stop undeploy deploy start
I finally figured that the deploy was issuing an implicit start, so I
changed it to:
  ant stop undeploy deploy
 
Hope this helps. - Richard

Many thanks Richard, I suppose that answers my question, albeit I was
hoping there was something more elegant that can be done other than
changing file permissions after installation.

what is the correct way to reload applications after copying files into
the installation directory? ant stop; ant start seem not to be designed
for that judging from the complaints from tomcat I get in catalina.out!!

thanks again

RE: question about deployment (including executables in war)

[Richard Mixon (qwest)]

Murad/Alon,

This has nothing to do with a SecurityManager. Murad is trying to run
the executables on the server - from one of his servlets I assume.

The problem is the fact that a war files is basically just a zip file.
It does not maintain the file attributes that are specific to a
particular operating system (e.g. execute, read-only, write, etc.).
Other archive formats do this (e.g. tar and Windows backup archives).

I believe the user's "umask" setting is probably used to set the
permissions - but Tomcat might do something different. Regardless, even
if Tomcat honors the umask setting, you would not want to change this
such that all files were marked executable when the jar was
uncompressed.

I am not sure you have much option other than to have a custom ant
script that alters the permissions after the files are deployed from the
war file. The jakarta-tomcat-5.5.x-deployer has a deployment script
(build.xml) that should be a good starting point.

Hope this helps - Richard

Murad,

I'm not 100% sure what you're asking -- like what do you mean by "jar
strips the execute file permissions from my programs"? -- but i'm
assuming you cant do it.   In fact, I will be more than a little
alarmed if a packaged web app can include and run arbitrary executables
unless specifically allowed to so by its server's SecurityManager, or if
the server is running without a SecurityManager.  That is, you cannot do
it unless you configure it OUTSIDE your web application.

Hope this helps,
Alon

RE: Controlling Tomcat Service From Ant

Yes, if your service  name is "tomcat" you can do something similar to
the following:

  

   

  

   

Check out the Ant "exec" task documentation.

Subject: Controlling Tomcat Service From Ant

Is there anyway to effectively start or stop the Tomcat 5.5 windows
service from within Ant?

I tried

  

  

but it produces an error message (although it works) and I don't know
what the corresponding command would be to restart the service. Is there
some standard way to accomplish this?

Thanks,

RE: Is Tomcat is an application server ?

[Richard Mixon (qwest)]

Antonio,

I will be generous and not assume you are arguing for arguments sake -
maybe just being a little too theoretical :)

I gave you some real world examples. If you want some third party
definitions, Google on the following:
  "Application Server" definitions
And you will see that Tomcat is quite comfortably contained in all 9 of
the definitions on that page.

As far as the points you bring up:
 - Remoting implies distributing your objects across the network - a
nice feature, but not often needed. Its talked about a lot - but for
most applications its just not needed.
 - Our Hibernate-based Tomcat application use Hibernate and jta.jar for
transaction services and it works quite well. We have most of the
advantages of declarative transaction demarcation.
 - It is really nice to have a messenging service or message broker, but
IMHO, the lack of such does not mean you cannot serve Java applications.

Have a good day - Richard

But it is not providing any services like transaction service, messaging
service, remoting. Without these how it can be considered as an
application server ?.

RE: Is Tomcat is an application server ?

[Richard Mixon (qwest)]

I think for most practical purposes Tomcat is an application server.

What Tomcat does not have is a builtin Enterprise Java Beans container -
however Tomcat supports many other parts of the J2EE spec.

Simply by the numbers, the vast majority of Java web applications do not
use EJBs - so Tomcat is just fine for most users. EJBs are not necessary
at all for building sophisticated and complex web applications. Tomcat
offers load balancing and clustering - which used to be only offered by
commercial application servers.

That said, there are some advantages to EJBs that can make the
additional complexity worth it. For some enterprise situations, you may
want an application server that is fully compliant with the J2EE spec,
such as Jboss, WebSphere, BEA or one of the other commercial packages.

RE: Tomcat keeps growing in size on Win32

[Richard Mixon (qwest)]

Ed.

Why don't you set a maximum heap size and see if it garbage collects
when it hits that size. Sounds like your application does not need that
much memory so try setting it to something like either:
  JAVA_OPTS=-Xms64m -Xmx128m 
Or 
  CATALINA_OPTS=-Xms64m -Xmx128m
This assumes you are starting Tomcat using the bin/catalina.bat script.

This will start it off with 64MB and let it grow to about 128MB
(probably a bit more in reality). It should garbage collect at that
point. If you are running Java 1.5 you can use the included Jconsole
tool to monitor memory usage. It will show you a saw tooth pattern if
the garbage collection is working properly.

Looking at Tomcat with the task manager, it grows unchecked from a boot

I have all the latest versions of everything:
Tomcat: 5.5.9

Isapi Redirector: 1.2.13

There is no website/database activity, just tomcat running.  I believe

I believe I have it narrowed down to java.io.File.DeleteOnExit that

this java routine has a known problem on Win32 systems.

I've been asked by one of the tomcat guys to get some hard evidence, but

Omar,

The web traffic analyzer software Michael referred to will work with any
web server, not just one with a java/JSP container such as Tomcat. There
is nothing "java-specific" about the traffic itself, just how the
traffic is produced.

Maybe we do not understand what you are trying to measure. Could you

> Hi all.

Just to be clear, the Apache HTTP Web server (http://httpd.apache.org)
is different than the Tomcat Java web application server
(http://jakarta.apache.org/tomcat).

Tomcat started as primarily a Java application server with basic HTTP
server support. Today it offers pretty complete and sophisticated web
server support - although not as complete as the standard Apache web
server.

As an application server, Tomcat does not support ALL of the J2EE spec,
just the parts necessary for what are often called "web applications" -
those primarily using servlet and JSP technologies with underlying

(Session beans or Entity beans) on Tomcat - but, IMHO, these are only
needed for the largest and more sophisticated enterprise applications.
The vast majority of web applications and web sites can run on Tomcat.
If you really need EJB support you can look at Jboss, WebSphere, BEA or
one of the other J2EE application servers. BTW, JBoss embeds a copy of
Tomcat as its JSP/Servlet engine.

Also, as a standard web (HTTP) server, Tomcat has basic support for CGI
and some level of support for PHP (seach the archive for this list).
Tomcat does not support the myriad of plugins, extension and "modules"
that Apache or some of the other web servers do. Still most sites can
easily be supported by Tomcat and the newer versions are very, very
close in terms of performance for serving straight HTML pages.

RE: Tomcat webserver or appserver?

Just to be clear, the Apache HTTP Web server (http://httpd.apache.org)
is different than the Tomcat Java web application server
(http://jakarta.apache.org/tomcat).

Tomcat started as primarily a Java application server with basic HTTP
server support. Today it offers pretty complete and sophisticated web
server support - although not as complete as the standard Apache web
server.

As an application server, Tomcat does not support ALL of the J2EE spec,
just the parts necessary for what are often called "web applications" -
those primarily using servlet and JSP technologies with underlying
database access. For example, you cannot deploy Enterprise Java Beans
(Session beans or Entity beans) on Tomcat - but, IMHO, these are only
needed for the largest and more sophisticated enterprise applications.
The vast majority of web applications and web sites can run on Tomcat.

I had a similar requirement in my app... We had a two-hour window per
day when the app was unavailable because background tasks were
processing.  The server was still up, and so was the app technically,
but it was not available.

I wrote a filter to take care of this.  I had a flag in application

the app unavailable during a time when it normally was available, I just
set the flag.  I also defined a single user that was still allowed to

We have an alternate httpd.conf file for Apache that is configured to
send everybody to "site down come back later" static site, then we
simply bounce Apache with the new config.

It's is not particularly subtle, but we're not a 24x7 site so much, and
it's more to let folks coming in know what's happening.

But it's simple and quick.

RE: How to do "Downtime" with a Apache/Tomcat webapp

[Richard Mixon (qwest)]

Len,

Sounds simple - but maybe I'm missing something. How do I do maintenance
on the site context (under webapp) if the context is being used to show
this simple page?

It may end up being simplest to alter (or swap in) the Apache config
file and do a reload. On my site the reload is pretty quick and I do not
think it disrupts active Tomcat sessions (in other contexts).

I've been thinking about the same problem, but I haven't gotten around
to working on it seriously.
 How about this: Instead of fiddling with the JkMount directives in
Apache, swap the web.xml in your Tomcat app so it points to a minimal
servlet that returns the "Out of service" page for all requests.
 Does that sound like it would work? It would be less disruptive because
you don't have to restart Apache (if there's more to the web site than
the one Tomcat app). Plus this will work with stand-alone Tomcat.

How to do "Downtime" with a Apache/Tomcat webapp

[Richard Mixon (qwest)]

I'm curious how folks handle letting users know that their webapp is
down when doing maintenance.

We've got a pretty standard setup. Our informational/static site is
served by Apache 2.0.x. We use mod_jk to link to a page in our
webapplications, triggering CMA for authentication and login. We run
Tomcat 5.5.x. Although we actually have Tomcat clustered, there are
still times when we need to make the application unavailable. (i.e.
doing database schema changes, etc.).

I would like for a page to be displayed that says the application is
temporarily not available.

So, what's the best way to do this?

One way I can think of is to modify the JkMount directives so that may
context name was not mapped to Tomcat, but instead to a static page -
the just do a restart. Trouble is some of our users have bookmarks into
various pages/actions in the application - we would somehow have to mapp
all pages that began with the context name to this single page. This
sounds a bit messy.

Is there a more straightforward way of doing this?

Thank you - Richard

Probably the release notes were already cut before the fix was created.
It is bug #34389. Here is the link:

Just so you are aware, jk2 is deprecated in favor of jk. As of version
1.2.10 of jk, most useful features in jk2 should be in jk.

See http://jakarta.apache.org/tomcat/connectors-doc/

This does not mean you cannot use jk2, it just has little support if
any.

If you mark them as transient, you may need need to implement a method
(ReadObject I believe) that properly initializes the transient
variables/objects.

There is an earlier post on this list where I describe how to do this. I
had a similar problem in that many of my classes had a Commons Logger
object stored in them. This had to be re-instatiated correctly when the
object was replicated.

Its hard to tell - you need to tell us more - e.g. what version of

I have gotten similar messages when I used the deployer app to undeploy
a webapp, but due to a lock on a file (i.e. a JSP file was open in a
text editor) all of the files were not deleted by the deployer app.

RE: Being lost in the mailing list

[Richard Mixon (qwest)]

Klaus,

Was there a reason you did not use the preconfigured Java 1.4, Tomcat
5.0.19 and JK connectors that come with SuSE Pro 9.1? These are listed
under the SuSE YAST "Install Software" panel. Just select RPM groups
Productivity->Networking->Web->FrontEnds.

The SuSE prepared README
(/usr/share/doc/packages/jakarta-tomcat/README.SuSE) gives a great
explanation of how to configure Apache and Tomcat. This is a bit
different than just just expanding the archives, but you get the
following benefits:

1) Tomcat is integrated into the Linux file structure (i.e. config files
are under /etc/apache2, /etc/sysconfig/j2ee, etc; shared files are under
/usr/share/tomcat, doc is under
/usr/share/doc/packages/jakarta-tomcat,...)

2) Tomcat is installed as a daemon that can be stopped/started/restarted
with rctomcat.

3) SuSE does provide security patches for their packages also that can
be automatically applied with their Online Update utility.

Hi Doug,

sorry, that I had to shout out, but I can see that every specialist gets
tons of eMails every day. And if he or she does not answer straight away
to some mails, the others will be dumped in a bin and ... lost.
And nobody answered by mails since days...

Thanks for your reply.

I have aquired a dedicated server with Suse 9.1 preconfigured. It came
with Apache 2.0.48, which is working well. I installed

- JDK 1.4
- Tomcat 5.0.28
- The latest binary package from mod_JK2

Apache and Tomcat are working well individually. The logs are showing,
that Tomcat accepts mod_JK2 well and is prepared to communicate on port
8009. It also creates the /conf/auto/mod_jk.conf, which I show later in
this text. Apache is not showing anything in the log. It just states
that it did not find the document in its normal public_html space, when
I try to call a JSP page.  But, I havn't modified the log-level (by the
way, where can I do that??).

There are soo many how-to's which are all doing different things. I
tried to find the essence from several. I must say at this point: I hate
to compile packages when I can use binaries. So, I did not follow
how-to's which asked me to do that.

All other infos are given below.

Can you do something with this info? Thanks for any help or hint!

Hassan, Could it be that you do not experience the long periods of
inactivity on weekends that we do?

This only happens on the weekend when we have low activity - sometimes
one of the Tomcat instances (they are clustered) will not see a login
request for about a half-day. During the week, the longest inactive
period is usually about six hours.

JDBCRealm changes from Tomcat 5.0.x to 5.5.x

[Richard Mixon (qwest)]

Has anything changed with the way that JDBCReal handles connection
timeouts in Tomcat 5.5.7?

We upgraded from Tomcat 5.0.19 to Tomcat 5.5.7 in production and are now
getting JDBC connection errors when the site has not been accessed for a
while.  This is happening when a user tries to login - we use a
JDBCRealm to authenticate the user.

We had this problem a while back but fixed it by adding the
"autoReconnect" parm, but now with Tomcat 5.5. we are having the problem
again. We are using MySQL 4.1.7 and version 3.1.7 of the MySQL JDBC
connector.

Here is the realm specification:

  



I also included the corresponding datasource defined for actual
application access.
The actual exception is below.

Would using the DataSourceReal provide any help here? I was thinking
that since it uses DBCP pooling maybe timeout recovery might be more
robust. I am trying to duplicate the problem in development now, before
trying the DataSourceRealm.

Thank you all for any suggestions or solutions.

Yeah, but you still need to uncomment the cluster element in the
server.xml.  Also if you have a multi-homed server you need to bind
multicast to a specific ip address.  Not to mention that you need to set
up mod_jk and apache to load balance.  It is not just adding a trivial
 xml element into the  web.xml that makes load balancing
with session replication work.

Anyway, just my thoughts on the matter

You need to implement either in memory session replication or persist

Hi,




I am load-balancing tomcat 5.0.28 using JK1.2 / AJP1.3.




For discussion, let's assume I have 2 tomcats (TomcatA and TomcatB)
load-balanced. When I shutdown one of the tomcats (Tomcat B), future
requests for TomcatB is correctly redirected and handled by the TomcatA.
However, the original session on TomcatB is not passed over to TomcatA,
and a re-login is required.




My question:


1.  Is it possible to pass the session information to TomcatA before
shutting down TomcatB? For eg. we want to perform servers upgrade, so we
down TomcatB, upgrade it, start TomcatB, before doing the same to
TomcatA.

RE: Tomcat clustering and NotSerializableException

[Richard Mixon (qwest)]

If you specify "transient" on the HttpServletRequest property in your
form bean (this does not seem like "good" design) you must make
provisions when the form bean is "de-serialized" on the other end to
initialize the property.

See my post on this list for the subject titled "RE: SOLVED -
commons-logging logger instances - how to initialize in replicated
session objects"r fo the details of one way to do this.

Thanks to all that replied.
Indeed a reference to the HttpServletRequest is held in my Struts form
(session-scope). The problem went away once I added transient to the
attribute.

My concern is when the session is replicated to other tomcat instances,
will a call to getRequest() always return null?

RE: skipping state transfer. No members active in cluster group

Randall,

See my answer to your posting on the subject "Tomcat Cluster". Both
Tomcat 5.0.28 and Tomcat 5.5.7 should work on Linux - at least on SuSE
Pro 9.2 and SLES9. However "failover restart" under session replication
works much better on the Tomcat 5.5.8 that is available as "alpha".

You might do better with a single post - this seems to be a duplicate.

whenever I start up tomcat for the first time, I receive this error
message.


INFO: Manager[/testapp], skipping state transfer. No members active in

After the delta manager starts, I receive this error.  Should I be

I have set  in my web.xml.  My server.xml has all the
clustering stuff enable. I have provided it below!!  I have started up
ethereal and I can see the multicast packets broadcasting.  The data
portion contains the ip address of the server.  Everything looks like it
should work.

RE: Tomcat Cluster

[Richard Mixon (qwest)]

Randall,

Below is the clustering section of my server.xml running under SuSE
Linux (SLES9). Things to check I can think of:

1. Is your server multi-homed (more than one network adapter)? If so you
"must" (at least from my experience) specify both "mcastBindAddr" and
tcpListendAddress as shown below. In my case I'm using a dedicated
adapter to connect the cluster over the private address space
192.168.11.x. Obviously the values are different for the Tomcat instance
on each server.
2. If after reviewing this it still does not work you can test that
multicasting is really working by using the utilities included in the
JGroups jars. See:
  http://www.jgroups.org/javagroupsnew/docs/newuser/node15.html#ItDoesnt
Work

Apparently this was too verbose for anyone to read.  I simply just don't
understand why each tomcat instance is failing to recognize any other
instance in the cluster.  Multicast messages are being broadcasted.  Is
there any configuration parameter I can turn on that will verify that
each tomcat instance can see the other instances???

The important thing to note here is that in the last line, I see
"INFO: Manager[/testapp], skipping state transfer. No members active in
cluster group."
At first I was thinking that multicast was not working properly.
However, I was researching the
Tomcat mailing list and found another thread discussing the same issue.
I tried to use the tool,
tomcat-replication.jar located on the CVS for tomcat.  I can see the
multicast sessions being generated between both servers using this tool.
I also started up ethereal, the packet sniffer.  I noticed that both
servers are generating multicast packets.

However after careful analysis of the packet information, I noticed that
my servers were looking for 127.0.0.1/4001 for the receiver port.
So I set the tcpListenAddress from "auto" to "10.111.22.163"  This
seemed to fix the problem with the multicast packets sending out the
incorrect listener addresses.  However, I am still getting the same
error...

"INFO: Manager[/testapp], skipping state transfer. No members active in
cluster group."

So here are my questions:
1. Is this really an error, or is session replication working and I am
not testing it properly?

2.What is the proper way to test that session replication is working
properly?  Can anyone provide me with code that works.  I am currently
using a bean that I declare with

RE: Tomcat clustering and NotSerializableException

[Richard Mixon (qwest)]

CoyoteRequestFacade is the first element in the stack trace - it is not
the session stored object that is causing the NotSerializableException.

As I said in my prior posting, to resolve this issue you need to:

1) Identify each object that you are explicitly storing in the session
and make sure it directly or indirectly (through inheritance) specified
that it implements Serializable.

2) Follow the chain from each session object to other objects that it
references and make sure they are ALL marked as serializable (again -
either directly or indirectly)>

That will fix your problem. These issues often do not come up until
either you:
1. Try and use session replication.
2. Try to persist sessions to a datastore and access from a cluster.
3. Try to persist sessions across a restart of Tomcat.

Also, please just reply to the list - not to the list and to the poster.

RE: Tomcat clustering and NotSerializableException

[Richard Mixon (qwest)]

Randall,
I know that session replication works in Tomcat 5.5.7 and it may also
works in 5.0.x (no experience). But to get failover restart to work
properly (i.e. restarting a failed node) I had to use Tomcat 5.5.7 with
a developer-supplied patch. This patch will be available with Tomcat
5.5.8.

RE: Architecture for application and web server

[Richard Mixon (qwest)]

JBoss just did a free webinar that covered the topic pretty well and had
some nice PowerPoint slides. You can access the recorded webcast here:
  https://jboss.webex.com/jboss/onstage/tool/record/viewrecording1.php?E
ventID=136098785

But basically, Apache uses Tomcat's AJP protocol to talk with Tomcat,
forwarding responses according to its mapping file and received
responses that Apache in turn returns to the browser.

RE: JDBC

[Richard Mixon (qwest)]

Sounds like you need application logic to do this - probably in
conjunction with using Tomcat's Container Managed Authentication (CMA).

Tomcat can validate the username against a database (see JDBCRealm at
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/realm-howto.html#JDBCRea
lm ).

However after being authenticated you can issue
  request.getRemoteUser();
to determine which user logged in. Then you can control how their
database queries are issued.

RE: Question for Tomcat Developers - How to Plug In Encryption for JDBC passwords

[Richard Mixon (qwest)]

Edmon,

I am not sure if I understand, but perhaps you should tak a look at Matt
Raible's Appfuse application framework at: https://appfuse.dev.java.net/

His solution uses:
 - SSL (optional of course, just a servlet parameter);
 - Container Managed Authentication;
 - a custom login servlet that encrypts the passwords (SHA is the
default, but algorithm can vary);
 - username and password stored in a database (the password is encrypted
using SHA).

The only exposure of the passwords might be in your web server "access"
logs. If that too is a concern, you could also take a look at trying to
do SHA encryption of the password on the client web browser using
Javascript - not sure if that's feasible or not. The login servlet would
then need to be adjusted appropriately (i.e. it would not need to do the
SHA encryption).

Under Tomcat 5.5.7 how to get "Username xxx successfully authenticated"

[Richard Mixon (qwest)]

Under Tomcat 5.0.19 I had a logger statement in my application context
that created a log file. This log file contained, among other things, a
line each time a user successfully/unsuccessfully logged in, similar to:
  2005-02-20 07:09:20 JDBCRealm[/stars]: Username xxx successfully
authenticated
or
  2005-02-20 07:09:20 JDBCRealm[/stars]: Username xxx NOT successfully
authenticated

I understand that under Tomcat 5.5.7 much of the logging is now handled
by commons-logging and log4j. Is there still a way to get the above
information? I have enabled logging using the instructions in the Tomcat
documentation at
  http://jakarta.apache.org/tomcat/tomcat-5.5-doc/logging.html
but do not really get what I am looking for (maybe I do not know what
specific logger statements to put in).

OK, I just had to re-read the comments in server.xml and think about my

Anyway I changed server.xml as follows:

RE: Tomcat 5.5.7 - error trying to replicate session on Linux

[Richard Mixon (qwest)]

BTW,

Each of my two servers has two network cards:
  a) One facing the internet;
  b) the second is a private connection between the two servers.

The second connection is intended for session replication.

Also, I did not specify an mcastBindAddr - though it probably should be
specified as the second network card.


Thanks - Richard Mixon

Subject: Tomcat 5.5.7 - error trying to replicate session on Linux


OK, we still have one more issue with our Tomcat cluster as we move to
our Linux environment.

For some reason, both instances (jvmRoute=srv1 and jvmRoute=srv2) see
each other at startup. We see that they each join the cluster just fine.
But when the first request comes through we get an exception timeout
trying to replicate.

Of course it works fine in our Windows development environment, but now
we are moving to our testing and production environments - SuSE Linux
SLES9.

Any ideas and suggestions are much appreciated. The catalina.log
messages for both Tomcat instances are below.

OK, yes it turned out to be one of those "dumb" configuration errors -
BUT also a difference in how Tomcat 5.5.7 (or maybe is is Commons DBCP

RE: Tomcat 5.5.7 cannot connect to mysql datasource - what changed? New approach

[Richard Mixon (qwest)]

Sorry to repost - but, except for some great suggestions from Shakeel, I
have not made much progress on this. To my way of thinking this seems
maddenly simple - either a config error or possibly bug. But what?

So my first place to start is to try and see where it is that the
userName property get mangled or swallowed. I've double checkd and it is
correctly specified in my context.xml But by the time the failure
occurs, it is a null or empty string.

So, how can I enable logging on my DBCP datasource so that I can see
where the connection "userName" property gets trashed? I've tried
putting org.apache.commons.dbcp in my log4j.properties, but do not seem
to get any additional output. Once I can see if things are passed
correctly here, I'll look at the MySQL Connector/J logging (although it
is not obvious how to do this).

Any suggestions?

Thanks - Richard

RE: Tomcat 5.5.7 cannot connect to mysql datasource - what changed?

[Richard Mixon (qwest)]

I am able to connect fine using the mysql client - either locally or
remotely. It is just with the web application using the JDBC driver that
it is not working.

Yes, maybe I'm at the point of having to do a simple JDBC application to
figure this out - though it seems silly given my application works in
Tomcat 5.0.19, but not in Tomcat 5.5.7.

Thanks - Richard

Try to hard code user name as the error shows '' as a user name. Also
you
can write a simple stand alone java program other than your web
application
to figure out exact problem. More things more problems. Less things
quick
findings, might help. By the way is your new MySQL communicating to you
via
any front end tool like SQL Yog or MySQL Front etc.

Thanks for the suggestion but we were already using DBCP 1.2.1. I
downloaded it and tried it again, but get the same error. Any other
ideas why the username would not be passed correctly when creating the

RE: Need simple app to test tc5 session failover - please

[Richard Mixon (qwest)]

Dan,

I just spent a couple of weeks working with Filip Hanik to get session
replication and failover working correctly on Tomcat 5.5.7 (at least for
the specifics of my situation). Failover was working fine, though I did
have to use a special listener to handle the replication of the
"jvmRoute" suffix with MOD_JK properly. What was not working was when
one restarted the failed node - some exceptions would occur and it would
not pick up the load properly.

I wrote a simple test case application that just updated a counter in an
object stored in the session each time a request was submitted. The
application is tiny, but the supporting jar files make the zip file
about 4mb in size.

If you can receive such a large email attachment let me know and I'll
send it directly to you.

Let me know - Richard

Sven,

Sorry I was unclear. I should have said that under Windows XP it
"compiles" fine. Same version of Tomcat (5.5.7), Ant (1.6.2) and similar
versions of Java:
XP:
 c:\EclipseProjects\workspace\stars>java -version
 java version "1.5.0_01"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_01-b08)

SuSE Linux

  Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_01-b08, mixed mode)
  user1:~/tc55-deployer>

What is even weirder (which probably means it is just a config issue
somewhere) is that when I set up a log4j.properties file to see if that
will illuminate the problem in jasper, I get a different exception
(NPE).

I've attached two runs below that show where this happens.

Hi,
   What do you mean by "Under Windows XP it deploys
fine." ?  I thought your problem is compiling?  This
deployer (manager webapps) compiles okay in XP and not
in SuSE?

RE: Tomcat 5.5.7 webapp not reload after META-INF/context.xml change

[Richard Mixon (qwest)]

Tevor,

Not sure if I have much to add, so much as just clarifying what you are
asking. Its of interest to me also.

If you are using the tomcat-deployer app, then file
"tomcat/webapps//META-INF/context.xml" normally gets
deployed to "tomcat/conf/Catalina/localhost/.xml". I
realize that the "tomcat/conf/context.xml" specifies that
META-INF/context.xml is a watched resource and if changed it should
reload the webapp. But are you also expecting it to redeploy
META-INF/context.xml to conf/Catalina/localhost/.xml ?? I
cannot see how that could happen.

OTOH, this may just reflect my rather narrow use of Tomcat 5.x - always
using tomcat-deployer to deploy my applications. Maybe someone else that
know more can comment and we will both learn a bit.

HTH - Richard

Subject: Tomcat 5.5.7 webapp not reload after META-INF/context.xml
change


Hi,

I have an unpacked ROOT webapp and if I change the
web.xml for it, the webapp gets reloaded. However if I
change the META-INF/context.xml for it, it doesn't get
reloaded. It's a WatchedResource too like web.xml. All
I'm doing is changing a context-param value in
context.xml (as a trivial example to explain my
issue).

When I change context.xml, I get this in the log:
Feb 13, 2005 6:11:39 PM
org.apache.catalina.startup.HostConfig checkResources
INFO: Reloading context []

So it looks like it should be reloaded, but it
doesn't.

In:
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/context.html

There is:

WatchedResource - The auto deployer will monitor the
specified static resource of the web application for
updates, and will reload the web application if is is
updated. The content of this element must be a string.


So I'm not dreaming.

I've also tried restaring the webapp with the manager
webapp and still no change.

Anyone else have the same issue? Am I doing something
wrong? Otherwise I'm going to enter it as a bug.

thanks,
Trev

RE: SOLVED - commons-logging logger instances - how to initialize in replicated session objects

[Richard Mixon (qwest)]

In case anyone else ends up with similar problems trying to get session
replication to work for objects that have a commons logging (or other
similar) non-serializable instance variable), here's how I solved it.

I created the following abstract class with the two methods "readObject"
and "readObjectNoData" (not sure this one is really needed). All of my
classes that might bet saved in a session and be replicated drive
directly/indirectly from this class. I was hoping for something a bit
more elegant, but it works for now.

Thanks Trond for the idea.

Any comments or criticisms are welcome.

Thanks - Richard

commons-logging logger instances - how to initialize in replicated session objects

[Richard Mixon (qwest)]

I have been working with Filip Hanik to get failover/session replication
working for my application. Finally it is working quite well. Hooray for
Filip!

However it did uncover one issue with the way I was handling the
commons-logging logger instances in my business objects that I store in
the HTTP session at times.

Given the following class:
  public class MyBusinessObject1 implements Serializable {
private static Log log =
LogFactory.getLog(ClassMeasurementFilter.class);

public void setShowXAxisAsPercentages(boolean
showXAxisAsPercentages) {
this.showXAxisAsPercentages = showXAxisAsPercentages;
if (log == null) {
log = LogFactory.getLog(ClassMeasurementFilter.class);
log.info("setShowXAxisAsPercentages - log was null");
}
if (log.isDebugEnabled()) log.debug("setShowXAxisAsPercentages
set to "+this.showXAxisAsPercentages);
}


I had to put the "if (log == null)" check in because when the objects
were replicated to another cluster instance and failover occured I would
get an NPE on the "log" variable.

Obviously having to put this "if (log == null)" check in is very awkward
and error prone.

Other approaches include creating a utility method in the base class for
my business objects. I'm not sure if this will give me the "logger per
class" that I've been used to so that I can readily identify where log
messages come from.

Are there any other approaches anyone would suggest?

Thank you - Richard

RE: Error FOP/BATIK ... PDFXMLHandler:253 - svg graphic could not be built"

[Richard Mixon (qwest)]

Bingo! That was it. I changed it from "file://" to "file:///" and all
works now. You earlier mentioned that might be it - but I was so focused
on the fact that it worked on Java 1.4.1 that I figured I had it
correctly.

That is weird though that moving past Java 1.4.1 breaks this.

Thank you once again, very much - Richard

Not sure this is particularly helpful, but I have come across similar IO
problems running Eclipse with Java 1.5.
I understand the problem is related to file locking and is an issue
specific to the new version of Java.
Unfortunately, my solution was to revert to 1.4.

It appears that you are using the deprecated JK2, not JK 1.2.8 that this

It is documented both in the server.xml, in the JK doc and in the Tomcat

Where is "jkstatus" function in jk version 1.2.8?

[Richard Mixon (qwest)]

I understand that the jk 1.2.8 connector supercedes the deprecated jk2
connector. I had read previous posting that indicated version 1.2.8 of
jk contained equivalent or better function/features than jk2.

However the jk2 connector contains documentation on a "jkstatus"
administration interface that seems to offer monitoring and (maybe) some
management functions.

I do not see this in the jk documentation. Is that feature there?

Thanks - Richard

Yes - jk2 is deprecated. From what I understand jk 1.2.8 has all
significant function of jk2 and is much more stable/reliable.

I am not sure whether it has the "jkstatus" function however.

BTW, My tests that showed failover working fine were performed with the
Tomcat 5.5.7 from Jan. 19th, 2005.

Roberto,

The short answer is yes, if you use Tomcat 5.x session replication and
failover loadbalancing such as the JK connector.

Please check the thread titled: "JK, Session Replication/Clustering, SSL
and failover in Tomcat 5" - it documents some of the configuration
needed for this to happen.

I have tested this and when one Tomcat instance fails, all sessions and
requests fail over seamlessly - the user is not prompted login again,
etc.

That said, I am having a problem on session synchronization when the
failed or shutdown instance is restarted and needs to replicate all of
the sessions back. Filip Hanik is looking into this further.

A major purpose of a NAT style firewall is to hide the private ip
addresses behind the firewall. If it allowed this information out it
would be a security compromise - the network topology behind the
firewall is to be kept secret.

I may be wrong, but I believe any web page you have been to that also
showed in the browser/client's internal private IP address must have had
a plugin - either an ActiveX or other type of plugin was probably
involved.

Sorry, I had just done the log4j and was trying to find a question to
match my answer/hammer.

What I did notice is that when I put in the log4j logging, a lot of my
catalina.out output is now going to tomcat.log, which is size
controlled. Did you see the same?

Also, IIRC my application "log.debug", "log.warn", "log.info" statements
are directed to catalina.out using a separate log4j.properties in my
application's WEB-INF/classes directory. You can use this to cut down on
the volume of your catalinat.out probably.

Otherwise, I cannot think of a good solution to just truncate the
catalina.out. Depending on the OS you are running under you might be
able to try and rename/truncate he file periodically, but that is not
very clean.

Filip, I believe you hit it once again. I've got code such as:

  ...
  public class ClassGrid implements java.io.Serializable
  {
static MessageResources msgRsrcs =
MessageResources.getMessageResources("ApplicationResources");
private static Log log = LogFactory.getLog(ClassGrid.class);
  

Both the variables "log" and "msgRsrcs" are static initialized and would
be a problem when replicating from one JVM to another.

The instance variable "log" should not even be static - can fix that.

The variable "msgRsrcs" I'm not sure how to fix. I've been fighting with
too much reference to Struts in my business logic for a while. I know
better, but have had problems seeing around how to handle such things as
i18n message resource handling which Struts does so well. Any
suggestions? I realize this is quite off-topic.

Thank you much - Richard

Filip,

Thank you so much. Setting expireSessionsOnShutdown="false" allowed
failover to occur without prompting the user to login again. Wonderful!

However, I then brought srv1 back up I got a number of exceptions when
they tried to re-synchronize with the still running srv2. Any ideas on
how to resolve this?

Mladen,

Thanks. I am trying to use the Tomcat Admin console to do this (I
believe this uses JMX). The only option it provides is to "delete" the
connection. I tried "deleting" the port "8009" connection in the first
Tomcat instance, leaving port 9009 running on the second Tomcat
instance. However JK continues to direct traffic to the first Tomcat,
apparently successfullly.

Any suggestions?

Thank you - Richard

Filip,

Thank you - that appears to be what I need. Unfortunately the only
documentation I can find is at:
  http://jakarta.apache.org/tomcat/tomcat-5.5-doc/catalina/docs/api/org/
apache/catalina/cluster/session/JvmRouteBinderValve.html

BEGIN-QUOTE
Valve to handle Tomcat jvmRoute takeover using mod_jk module after node
failure. After a node crashed the next request going to other cluster
node. Now the answering from apache is slower ( make some error
handshaking. Very bad with apache at my windows.). We rewrite now the
cookie jsessionid information to the backup cluster node. After the next
response all client request goes direct to the backup node. The change
sessionid send also to all other cluster nodes. Well, now the session
stickyness work directly to the backup node and traffic don't go back
too restarted cluster nodes! At all cluster node you must configure the
JvmRouteSessionIDBinderListener  with
JvmRouteSessionIDBinderListenerLifecycle  Add this Valve to your
clustered application or setup it to context default
conf/enginename/hostname/context.xml.default for all host application


  



END-QUOTE

I put the valve statement in my conf/context.xml. But this does not seem
to be enough.

But where can I find information on configuring the
"JvmRouteSessionIDBinderListener  with
JvmRouteSessionIDBinderListenerLifecycle"?

Thank you - Richard Mixon

yes, There is code that takes care of that scenario, I believe it was
peter who coded it.
There is a valve called JvmRouteBinderValve that peter wrote, that you
enable for your context.
It will rewrite the session id for, and broadbast it to the cluster.

Filip,

Pen does not really help me out.

My problem is JK I am pretty sure.  It is appending ".srv1" to the
session. When srv1 is stopped, it detects this on the next request and
routes the request to srv2. However I notice in the JK output that it
now has ".srv2" appended to the session, which of course does not exist,
and I get prompted to re-logon.

Below is the debug output from JK showing the failover attempt.

Any other suggestion?

Thank you - Richard

RE: JK, Session Replication/Clustering, SSL and failover in Tomcat 5

[Richard Mixon (qwest)]

Filip,

Thank you - that appears to be what I need. Unfortunately the only
documentation I can find is at:
  http://jakarta.apache.org/tomcat/tomcat-5.5-doc/catalina/docs/api/org/
apache/catalina/cluster/session/JvmRouteBinderValve.html

BEGIN-QUOTE
Valve to handle Tomcat jvmRoute takeover using mod_jk module after node
failure. After a node crashed the next request going to other cluster
node. Now the answering from apache is slower ( make some error
handshaking. Very bad with apache at my windows.). We rewrite now the
cookie jsessionid information to the backup cluster node. After the next
response all client request goes direct to the backup node. The change
sessionid send also to all other cluster nodes. Well, now the session
stickyness work directly to the backup node and traffic don't go back
too restarted cluster nodes! At all cluster node you must configure the
JvmRouteSessionIDBinderListener  with
JvmRouteSessionIDBinderListenerLifecycle  Add this Valve to your
clustered application or setup it to context default
conf/enginename/hostname/context.xml.default for all host application

RE: loadbalancing with mod_jk 1.2.8

[Richard Mixon (qwest)]

John,

>From what I gather, this is the purpose of the properties "local_worker"
and "local_worker_only" properties in the workers.properties file. They
are documented at the bottom of this page:
  http://jakarta.apache.org/tomcat/connectors-doc/config/workers.html

Unfortunately the explanation is not clear - partially due to the
English. I say this somewhat apologetically - realizing of course that
the writers command of English if probably far, far better than my
command of their native language.

>From what I do understand:
 1) At the point that you decide to do maintenance on one machine, you
need to change your workers.properties and set local_worker=0 for that
particular machine.
 2) Then do a "reload" on your Apache configuration.
 3) JK will then stop directing new traffic to the designated machine.
 4) After all sessions have expired or quiesced you can stop that Tomcat
instance and do the maintenance.

The above scenario may work for some, but not for my case. I have users
that may work on a session for several hours sometimes. So I need to use
JK and Tomcat session replication which is supposed to let you use the
"ant stop" command and have all traffic immediately handled by the other
Tomcat instances. There is a separate active thread on this issue. I see
Filip just mentioned a new valve "JvmRouteBinderValve" that may help
solve my problem.

Hope this helps - Richard

 I do know how to stop TC, I said the whole idea for people to know I
was
thinking about an HA set up using Apache + TC instances

 The part I am most interested in is,namely; how to make the connector
at
run time NOT send NEW connections to one the tomcat instances being used
for
loadbalancing
