Re: How to deploy a custom DynamicMBean
The docs you've described are mostly for if you want custom Tomcat
components (such as Valves or Realms). You'd want something basic like:
MBeanServer mserver =
(MBeanServer)MBeanServerFactory.findMBeanServer(null).get(0);
ObjectName loader = new
ObjectName("Catalina:type=WebappClassLoader,path=/myapp,host=localhost");
ObjectName mylight = new ObjectName("MyApp:type=lightbulb");
mserver.createMBean("scratch.LightBulbDynamicMBean", mylight, loader);
Of course, you have to change the host and path to match your app, and the
domain of the loader to match the Engine name if you've changed it from its
default value.

Use of LANG=en_US in Tomcat configuration file
Can someone please explain what's the use for this line in the tomcat configuration file? What's the use of it (the line is commented) and what effect does it have on a running container? What value can it take as well? Any other variables can be set in the same file? Thanks in advance.

Tomcat 5.0.19 not dispatching to servlet
Hello,
I'm running Tomcat 5.0.19, Apache 2.0.49 and mod_jk2-2.0.4, stand alone (NOT
in-process), on a W2K box. Tomcat is listening on port 8009 (port 8080 is
commented out) and Apache passes all requests of type "/psi/servlet/* to
Tomcat, via the workers2.properties file redirect (see below). I have a
servlet defined in my web.xml file to load up at Tomcat startup. I've
verified that the servlet is loading by writing debugging information in the
servlet init() method. So, the servlet is loading at Tomcat startup but
when Apache redirects the servlet request to Tomcat, I get a 404 served up
by Tomcat. I know this because the Tomcat version is displayed at the
bottom of the error page. I'm using a context configuration file to define
my path and docbase (see below). This same configuration works with another
application that uses Struts, .jsp and servlets.
Any ideas? I'm getting desperate...
Thanks,
Dave

How to deploy a custom DynamicMBean
I'm looking for help from someone with some experience deploying
DynamicMBeans to Tomcat.
In short, my questions boil down to some very basic information gaps:
once we have a DynamicMBean,
(1) What do we need to add to the server.xml file?
(2) What other configuration file(s) need to be created/edited?
(3) What are the contents of those files?
Please feel free to tell me to "Read The Fine Manual" ... but I've had
some trouble locating meaningful docs. If the answers I seek are
documented somewhere, a pointer to those docs would be greatly
appreciated. Otherwise, I would be happy to put something together,
maybe a small how-to, once I have things working. I think a step-by-step
set of instructions around a concrete (if very simple) example would be
useful to others trying to do similar things.
Let me share what I've learned so far:
According to the "MBean Descriptor How To"
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/mbeans-descriptor-howto.html
Once we have an MBean, it looks like we need to create a
mbean-descriptor.xml and add it to the list of "descriptors" in the
ServerLifecycleListener tag. Something like:
I have tried this and get a very curious error:
org.xml.sax.SAXParseException: The processing instruction target
matching "[xX][mM][lL]" is not allowed.
Should it be the "GlobalResourcesLifecycleListener" tag? Using that
seems to avoid the stack-trace, but then it doesn't look like the custom
DynamicMBean is being instantiated, so if this is correct, there's
something else missing.
I found one reference to someone else having similar confusion but was
not able to use the information to good advantage:
http://www.junlu.com/msg/93635.html
I didn't see a description the "Engine" tag suggested in this thread.
Assuming we are supposed to create "mbean-descriptor.xml" files (and the
SAXParseException can be over-come) ... are these files usually packaged
up in the jar file (with the MBean class files) deployed to server/lib?
That's where I've put it, for the moment, but I am not sure this is a
good practice. It doesn't seem right to package JMX Agent specific files
inside the jar; a different file is needed with JBoss, for instance.
I have not seen a good example of what this descriptor file is expected
to contain, especially for DynamicMBean where the attributes my not be
known at deployment time. If you know of an example, please post the
url.
Next the Descriptor How To suggests that "You may also add MBean
descriptions for custom components in
org.apache.catalina.mbeans.mbeans-descriptor.xml file." After some
searching, I think this file is normally only contained in the
catalina.jar file in the server/lib directory. This feels like messing
with the Tomcat internals. Ideally, I wouldn't want our new MBeans
exposed as part of Tomcat itself. So, I don't understand when or why we
should modify that file.
To provide an DynamicMBean deployment example, I've attached a simple
"LightBulb" class to be managed, as well as a very naive DynamicMBean to
manage it. If we really had an application this simple, we probably
wouldn't be using a DynamicMBean, but I've tried to create something
simple enough to let us focus on the deployment issues.
Any input (kind or cruel) is welcome.
Cheers,
-- Eric

QM,
I'll try the "experiment" that you suggested, but FYI, there are no .WAR
files in either the unzipped directories from just unzipping, or in any
subdirectories under my working [TOMCAT HOME]. If those extra .xml
files got created because of #1 above, would you expect to find some
files named .war?
Also, there are no directories named "META-INF" or files called
"context.xml".
I'll post back in a bit after I've tried the bit with changing the
Engine name...

DBCP and SingleSignOn
It does not appear that SingleSignOn uses DBCP, in fact it looks as if it opens a single connection the first time it is used and then attempts to re-use that connection indefinitely. From my understanding on how Tomcat works there would only be a single SignSignOn Valve instance so everyone attempting to sign in would be trying to use the same connection. In addition it also has the side effect that if your DB is on the other side of a firewall and no one signs in for some time and your firewall kills unused connections that the next time someone attempts to sign on the application appears to stall as Tomcat, SingleSignOn and your database try to figure out why you got a SocketException. So my question is... Is there any reason why SingleSignOn does NOT use DBCP? And is my logic above right that everyone signing in is going to be trying to use the same database connection? Thanks for any insight that you can give me... Keith Have you ever noticed that the word 'complaint' and 'compliant' are spelled almost the same except the transposition of a single letter.

There are 2 ways for the {tomcat}/conf/{...}.xml files to be created:
1/ META-INF/context.xml is extracted from a WAR file when it is deployed
and copied there.
(Unless the matching XML file already exists under conf/, in which case
the WAR file's context.xml is ignored)
2/ The file is manually copied there by someone.
The servlet-examples.xml and jsp-examples.xml files are included in the
default Tomcat distro, and remain there unless explicitly removed. For
example, to address the issue mentioned in point #1, I periodically
clear out the conf/{...}/*.xml files.
Here's an experiment and learning exercise for you: edit server.xml,
change the element's "name" attr, then bounce Tomcat. Notice
under {tomcat}/conf/ there's a new dir that matches the name.
What files are under that directory, now?
I realize this may be confusing at times because there's a lot to
absorb when leaping into Tomcat (or any container, for that matter).
Give it time, and soon you'll know all of this by heart. =)
btw, if you use separate Tomcat instances (check the docs for
CATALINA_HOME vs CATALINA_BASE) then this is moot: the only
context-related XML files under {instance dir}/conf/ will be the ones
for your webapps, not the samples. ;) But that's another story for
another day.

serialized objects invalidating session
I have a web application that is storing 2 objects in each user's session. I recently made each of those objects implement the Serializable interface. What I now notice is that if I stop and restart Tomcat (Tomcat 5.0) the sessions are no longer valid and as a result, the serialized objects are gone. However, if I refactor those the 2 objects to no longer implement the Serializable interface, then my sessions are recovered from disk after server stop and start, but of course, my non-serialized objects are no longer around. Help! BTW, I am not seeing any errors in the Tomcat logs when I do serialize those objects. Regards, Carey

Tomcat 5.0.27 Win2k sp4, service.bat JVM Options
Hello, I am running Tomcat 5.0.27 on a Windows 2000 sp4 machine as a service. It appears as though the JVM settings that I am trying to use are not being recognized by the system, variables such as -Xms512m or -Xmx512m. Here is what I have tried: 1. Configure Tomcat program that installs with Tomcat5. In 5.0.27 there are boxes for initial heap, etc. under the Java or JVM tab where I tried setting values. I also tried adding them to the Options box. Restarting the service shows they are not detected. 2. Editing the registry. I have seen many ways to do this. I've tried the set where I add "JVM Option Count"=x and "JVM Option Number 1", etc. I have also tried adding the settings to the registry as "JAVA_OPTS", "JAVAOPTS", and "JAVAOPTIONS" to no avail. And where in the registry do I put it really? Does it go under Current Control Set->Services->Tomcat5 or does it go under Software->Apache blah blah->procrun or whatever it is. 3. Using service.bat. This is just confusing. There's no documentation that's worthwhile about procrun. The changelog makes it look like adding #'s instead of spaces was fixed in 5.0.23, but I don't know if that is the case or not. Anyway, can anyone post me an example of how to modify service.bat to include -Xms, -Xms, and -Xss? Maybe I'm putting it in the wrong place? I know if I have an environment variable called JAVA_OPTS and I run from catalina.bat that my JVM settings definitely show up correctly. Why is it so hard for them to show up as a service? Using Windows sucks, but I don't have a choice. Any help will be greatly appreciated. Thanks, b _ Dont just search. Find.

RE: form-based login username and password encoding issue
You should be able to do this although I have never tried. Depending on your version of tomcat, you may need to adjust a few settings. See below. Mark REQUESTS There are a number of situations where there may be a requirement to use non-US ASCII characters in a URI. These include: - Parameters in the query string - Servlet paths There is a standard for encoding URIs (http://www.w3.org/International/O-URL-code.html) but this standard is not consistently followed by clients. This causes a number of problems. The functionality provided by Tomcat (4 and 5) to handle this less than ideal situation is described below. 1. The Coyote HTTP/1.1 connector has a useBodyEncodingForURI attribute which if set to true will use the request body encoding to decode the URI query parameters. - The default value is true for TC4 (breaks spec but gives consistent behaviour across TC4 versions) - The default value is false for TC5 (spec compliant but there may be migration issues for some apps) 2. The Coyote HTTP/1.1 connector has a URIEncoding attribute which defaults to ISO-8859-1. 3. The parameters class (o.a.t.u.http.Parameters) has a QueryStringEncoding field which defaults to the URIEncoding. It must be set before the parameters are parsed to have an effect. Things to note regarding the servlet API: 1. HttpServletRequest.setCharacterEncoding() normally only applies to the request body NOT the URI. 2. HttpServletRequest.getPathInfo() is decoded by the web container. 3. HttpServletRequest.getRequestURI() is not decoded by container. Other tips: 1. Use POST with forms to return parameters as the parameters are then part of the request body. RESPONSES = HTML META tags are ignored by Tomcat.

RE: Memory Usage - Tomcat 5.0.25
Hello Yaov, You are correct I do have a few static varibles that point to running threads and some other objects. When the application is shutdown I ensure that each thread is destroyed and all static varibales are set to null, including thread identifiers, this should let my call to GC clear the memory. You are also right in saying that i should not depend on undeploy to reclaim all memory that the webapp was using, and I don't. Like I mentioned I do make sure all static variables get set to null before the application shuts down. It would be understandable if not all memory utilized by the webapp is reclaimed, but in my case absolutely no memory is being reclaimed. For example, say, i start tomcat and it starts with 30M initial memory usage without the application. Now when i deploy the application the size jumps by 8M to 38M. As the app is undeploy and re-deploy the memory usage jumps from 38M to 46-47M. Now this, if I am not wrong, is not how things should be. I would appreciate anymore suggestion that you or anyone may have. Regards, Nandish -Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Monday, August 09, 2004 1:35 PM To: Tomcat Users List Subject: RE: Memory Usage - Tomcat 5.0.25 Hi, I have a couple of ideas. One is that your webapp maintain static or shared references to objects that prevent them from being garbage collected, and therefore memory from returning to the heap. Another is that a webapp undeploy is not guaranteed to reclaim all memory used by the webapp anyways so to count on this behavior is not smart. It is expected that every time you reload your webapp the overall memory usage of the server will go up a bit, as not all objects are gone (for example, if you have a static reference than the old classloader and anything that references it strongly will remain in memory).

Tomcat 4.1 and LD_ASSUME_KERNEL=2.4.1
Hi all, I am having problem where Tomcat 4.1.27 just stops after some random period of time. I am on RH9 and JDK 1.4.2. This seems to be the same problem reported earlier and a recommended fix was to set an environment variable LD_ASSUME_KERNEL=2.4.1. Can I simply put an "export LD_ASSUME_KERNEL=2.4.1" in my setenv.sh file? Also, I have heard other recommended values, such as LD_ASSUME_KERNEL=2.2.5; how would I find out which one to use? - Steve Hello. Is this the same problem I also asked yesterday about in thread "All threads are busy ... servlet status 75" Somewhere I read about setting the LD_ASSUME_KERNEL to 2.2.5 But I also read somewhere that this didn't help (www.junlu.com/msg/14450.html) QM wrote: > > On Thu, Jun 17, 2004 at 03:54:08PM -0400, Bradley Glonka wrote: > : Tomcat installaion on Red Hat Version 9 intermitnently stops > : Responding. > :Kernel 2.4.20-9 > > RedHat's custom kernels have backported the NPTL (Native Posix Thread > Library) routines from 2.5/2.6.

Tomcat 5.0.19 not dispatching to servlet
Hello,
I'm running Tomcat 5.0.19, Apache 2.0.49 and mod_jk2-2.0.4, stand alone (NOT
in-process), on a W2K box. Tomcat is listening on port 8009 (port 8080 is
commented out) and Apache passes all requests of type "/psi/servlet/* to
Tomcat, via the workers2.properties file redirect (see below). I have a
servlet defined in my web.xml file to load up at Tomcat startup. I've
verified that the servlet is loading by writing debugging information in the
servlet init() method. So, the servlet is loading at Tomcat startup but
when Apache redirects the servlet request to Tomcat, I get a 404 served up
by Tomcat. I know this because the Tomcat version is displayed at the
bottom of the error page. I'm using a context configuration file to define
my path and docbase (see below). This same configuration works with another
application that uses Struts, .jsp and servlets. Any ideas?
Thanks,
Dave

RE: Memory Usage - Tomcat 5.0.25
Hi, I have a couple of ideas. One is that your webapp maintain static or shared references to objects that prevent them from being garbage collected, and therefore memory from returning to the heap. Another is that a webapp undeploy is not guaranteed to reclaim all memory used by the webapp anyways so to count on this behavior is not smart. It is expected that every time you reload your webapp the overall memory usage of the server will go up a bit, as not all objects are gone (for example, if you have a static reference than the old classloader and anything that references it strongly will remain in memory).

Multiple instances of Tomcat.
I am working on converting a standalone content management system that has embedded Tomcat and an admin servlet as one of its components. My intent is to turn this application into a servlet itself running under a standalone Tomcat5. My question: is it possible to run embedded Tomcat5 within a servlet that is itself running under Tomcat5? Second question: would it be possible if this works for the inner servlet to access memory (objects) instanciated by the outer servlet? Note: I have noticed that servlets within the same context have access to each others memory, while servlets of different contexts do not. Anyone care to confirm, elaborate, explain, contradict?

Using a META-INF\context.xml doesn't work as expected with Manager app .war upload
Hi, I use Tomcat 5.0.19. I'm playing around with the Manager web application and want to deploy a .WAR file that contains a META-INF\context.xml deployment descriptor. Deploying the .WAR file using the upload feature works, and the context.xml that I put into the META-INF\ is copied (but renamed?! to utility.xml) to conf\Catalina\localhost as expected. The problem is that I provide this context.xml: So I would suggest that the .WAR file is uploaded and unpacked to webapps/tests/utility. But it is not! It's straightforward unpacked to /webapps/utility. Finally the docBase in utility.xml (alias context.xml) doesn't match the real location. :-( Thus the context is not accessible. Is this the expected result? Is it only possible to deploy a context directly to webapps when using the manager application and the META-INF\context.xml? - Or am I missing something.

QM,
A couple of questions:
1) Any idea why d_l has only the 3 .xml files in
[tomcat]/conf/[...], whereas I have a bunch? As I indicated in an
earlier msg, I didn't create them.
2) When you and others refer to "context.xml", are you referring to a
file that is literally named "context.xml", or do you mean "an file
containing the webapp's that is named .xml"? I've
seen references to "context.xml" in various places, but there are no
files named "context.xml" in my Tomcat subdirs.

RE: Tomcat stops responding
Unfortunately my log output has not been consistent. I have fixed that problem and should get solid logs now. My application currently uses SingleSignOn with a JDBCRealm. Besides that I have no other Database connections. I didn't mention that before, but I wanted to put it out there in case there is something specific about SingleSignOn or JDBCRealms that might trigger someone's memory.

You're overthinking this. =) When the database is down (or otherwise unavailable) attempts to use DB-related objects (Connection, Statement, ResultSet, etc) will yield SQLExceptions. In turn, that exception (or even better, an app-specific exception that shields code up the chain from datasource-specific exceptions) will get passed back to the presentation layer, at which point you can serve an appropriate error page. For example, assuming a simple Page Controller setup for some use case: your code will do some processing and dispatch to an appropriate view. If the code is successful, dispatch to the "success" page. If you catch a data-related exception, dispatch to the "database error" page. This is why I said before, there's no need to tell the app that the DB is down: it will know. ;) There are certainly other (and more complicated) ways to handle this, which will all do pretty much the same as what I've outlined above. It sounds like you're more familiar with stateful/fat clients that maintain a constant connection to the central server, and that you can send them a message when the DB is down.

If there is no context.xml, as with the examples, then Tomcat won't
create (copy) the file to {tomcat}/conf/{...}.
Take note: if you are using a WAR file and make changes to the internal
context.xml file, delete the one under {tomcat}/conf/{...} before you
bounce the process. At least for now, Tomcat doesn't check a whether a
WAR file's context.xml is newer than its copy under the conf dir.

On my system, it looks like there IS a .xml, for each webapp, and in each case, the is in these .XML files. Thanks re. the 'examples' question. That was causing me to wonder if there was something wrong with my installation. As to your implied question above of "why do I have all the .XML files, whereas you only have 3?", is it possible that whoever built the Tomcat installation created it that way? FYI, I did my Tomcat installation from the Tomcat binaries for 5.0.27 (in a .zip file) that I found at http://www.apache.org, but I didn't look closely at what was where after I unzipped the distribution, so it may be that the .XML files were already in the distribution. So I don't know if they were there immediately after the unzip. All I know is that they're there now, and I didn't create them. It does seem that you have to manually create these .XML files, as with the new.xml, which I had to create manually, because when I started Tomcat up without the new.xml file, I saw some errors on startup.

Newbie - J2k uri mapping to subfolders via Ajp13?
Hi,
I'm running j2k (isapi_redirector2.dll) under IIS 5.1 to connect via
Ajp13 to my server.
My "workers2.properties" is like this:
[shm]
file=${serverRoot}/shm.file
size=1048576
# socket channel for myapp on myhost.
[channel.socket:myhost:8081]
port=8081
host=myhost
# define the worker
[ajp13:myhost:8081]
channel=channel.socket:myhost:8081
# Uri mapping
[uri:/myapp/*]
worker=ajp13:myhost:8081
This works fine.
Is it possible to change the configuration in "workers2.properties" so
that the url http://myhost/myapp points to a subfolder like:
http://myhost:8081/subfolder?
TIA
Heinrich

If you did your homework, then you'd know the solution to OutOfMemoryErrors is specific to your web application and your server configuration. You may have a leak, or you may not, and no one but you can tell for sure: get a profiler and use it. You may obtain better performance by tuning the JVM's garbage collection (using the variety of applicable -X runtime options), and you may not, especially if you have a serious leak. And adding memory can't hurt that much, but may not be required: again you must test it yourself. There are no shortcuts for OOMEs that lead to sustainable long-term solutions.

form-based login username and password encoding issue
hi all; in my application, i let my users register to my site (with username, password , etc.. ), when they do i programatically take their username and password and move it to the authentication tables of the datasource realm so they can authenticate. i am using form-basd login. problem is that when a user enters a username ans password characters that are not western europian, the authentication process fails. is this a constraint of the fact that the user and password are sent as parameters in the URL? (j_user, ...). are the parameters in the URL not encoded as UTF-8? can i control this? thanks in advance. _

serving pdf with CLIENT-CERT authentication
Hi,
I'm running an application with SSL-client certificate authentication.
It works fine, except one servlet that serves a PDF document. Yet that
servlet worked fine on a Tomcat 4.x.
Now, on a Tomcat 5.0.25, I get the following problem : when my Internet
Explorer 6 requests for the servlet, I get a popup ("open", "save",...),
which I didn't get with my Tomcat 4.x, and when I try to "open" or
"save" the PDF, Internet Explorer complains about the server
unavailability...
Enabling SSL trace, I don't see any error and I can see a few "WRITE:
SSLv3 Application Data" correspunding with the PDF served.
That's all the more surprising since it works fine on Tomcat 5.0.25 if I
use SSL with server authentication only and no security constraint in my
web app.
Any idea ?

Re: Newbie - JDBC problem "Name is not bound in this context"
Can you clarify what version of Tomcat you are using? It seems that there is a configuration change .. from Tomcat4 to Tomcat5 .. the context goes in to \conf\Catalina\localhost\.xml .. for each webapp. Here is a reference I found in my own digging around .. ___ http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/context.html which states .. Please note that for tomcat 5.x, unlike tomcat 4.x, it is NOT recommended to place elements directly in the server.xml file. Instead, put them in the META- INF/context.xml directory of your WAR file or the conf directory as described above. ___ BUT .. in my Tomcat 5.0.27 .. I only see three .xml files in above location .. admin.xml balancer.xml manager.xml no other .xml files (context.xml files) show up such as jsp-examples.xml servlets-examples.xml I don't understand why you have jsp-examples.xml and I don't see that file (only the three above). " so I added just the ResourceLink to jsp-examples.xml, bounced Tomcat, and VOILA!!! It worked!! " Where is the default context information when there is no .xml? There is no context entry in server.xml. ... And I confirm that there is no webapps\examples\in my configuration .. replaced, it seems, by the two separate webapps above. ...

Tomcat manager app stops responding
I am having two problems with the Tomcat manager: 1] After my web application has been running for some time then access to /domain/manager/html never responds. It doesn't give me any kind of error, the browser just continues to process the request without ever timing out. Any ideas? 2] Tomcat manager does NOT delete my .war file on undeploy, so I have to then access the server in a different manager, stop it, delete the file manually, start it, then upload the new .war file and deploy it. Which sometimes takes several times to deploy properly if I am referencing the root context but not any other context. Any ideas? Thanks in advance, Keith Have you ever noticed that the word 'complaint' and 'compliant' are spelled almost the same except the transposition of a single letter. I wonder why that is?

RE: Problems with file encoding
You still can. If you look in catalina.bat ... %_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% So, just make sure you set %CATALINA_OPTS% e.g SET CATALINA_OPTS=-Dfile.encoding=ISO8859-1 If you are using a Windows Service you need to modify service.bat Allistair. > -Original Message- > From: Francisco José Arnau Vives [mailto:[EMAIL PROTECTED] > Sent: 09 August 2004 09:10 > To: [EMAIL PROTECTED] > Subject: Problems with file encoding > > > One month ago, I have installed tomcat.5.0.25 over my > production server.

[OFF TOPIC] J2EE/Tomcat Build Process
Hi All, I am currently trying to streamline our team's build process here using Tomcat as our servlet container. For a while the way I had it setup was that we had 1 instance of TC running on a dev server and 1 instance on production. Each developer would checkout only the code they will work on from VSS. They would not have read-only latest version copies of the other source on their disks. They would then use an Ant build script to compile their checked out classes directly to TC's classes, and a separate Ant target for copying JSPs and so on to the webapp folder. This method as far as I was concerned got around the code overwrite problem - where if both developers had a version of all source using a Get Latest Version, each time they compile they would overwrite the same instance compiled classes. Recently, I have installed a TC per developer on the server. My idea is that we will use the Eclipse VSS plugin and WILL all perform Get Latest Version. However, because each dev has their own dev instance, they will not overwrite any changes by other developers on source they have not got checked out. Then, I am thinking, each developer must only ever checkin stable compilable source, so that when other devs Get Latest Version from the root of the source tree, it will still compile. When I do a build, I am thinking that all source must be checked in, then a Get Latest Version, then run an Ant script to compile and generate a WAR for staging and production deployment. Finally, I have just this second had a call from IT saying the 3 instances on our dev server are brining virtual memory to its knees - which begs another question - should each developer have a locally installed TC rather than server based? I would be very interested in others' development/deploy processes with mult-developer Tomcat environments to cross-check my ideas. Kindest Regards, Allistair. --- QAS Ltd.

Problems with file encoding
One month ago, I have installed tomcat.5.0.25 over my production server. In older versions of tomcat I included the lines ''CATALINA_OPTS="-Dfile.encoding=ISO8859-1" in my init script of tomcat in order to solve little problems in the encoding of files, but now with this version I have problems with the encoding of files and wheh I insert caracters as (á.é,í...) in forms. can you help me with this matter?
