RE: Using XInclude in tomcat's config files
-Original Message- From: Shankar Unni Try an entity instead of xinclude? Not many parsers are good for xinclude as yet (a mainly uninformed statement). Entity resolution is easier if the parser is setup correctly. Oh, that's what we are doing now, but entity resolution doesn't have a concept of relative paths. Does your parser support xml:base? That makes relative paths work. All in all, entity includes are inflexible and a terrific pain to work with. Its an alternative. regards DaveP -- DISCLAIMER: NOTICE: The information contained in this email and any attachments is confidential and may be privileged.

Re: Search engine friendly URLs
There's a filter that does URL rewriting already, urlrewrite ,
mod_rewrite would be okay but who wants to run mod_jk - apache as
his/her development environments.
http://tuckey.org/urlrewrite/
The only problem then is generating the links. I think the original
question was posted on the struts group the other day and that he's
using html:link tags. I'd change these for jstl for the links.
so rather than
html:link page=/action.do ..
you'd use something like..
c:url var=link value=/action.do
c:param name=name value=somevalue /
.. and so on
/c:url
this will render to
/appname/action.do?name=somevalue
so now lets say you've set a boolean called cleanURL, this means you
can switch the functionality off if you want to deactivated urlrewrite
during development. An init param in web.xml i suggest would be the
best place, but for now lets set in the page.
c:set var=cleanURL value=true /'
c:if test=${cleanURL}
c:forTokens var=badChar items=?, delims=,
c:set var=cleanLink value=${fn:replace(link,badChar,'/'}'' /
c:set var=link value=${cleanLink} /
/c:forTokens
/c:if
a href=${link}Link/a
Once you've set urlrewrite filter up you'll want something like this.
rule
from/action.do/*/*/from
to type=redirect/action.do?$1=$2/to
/rule

Subject: AW: Search engine friendly URLs
Hi
If you want to be able to scale your application, you need to be able
to
move the static image handling out of tomcat to a separate web server.
Using
Tomcat to handle both application chores and web serving chores will
limit
the overall scalability of your system.
I strongly disagree.
Tomcat is nearly as fast as apache in serving images.
So, yes, you can save a little time using apache, BUT remeber that the
apache slows tomcat down. You need cpu-cycles for apache, for mod_jk
and
additionally for tomcat. Those cycles for apache and mod_jk are not
nessesary, since tomcat can work standalone.
So the question comes down to decide wether the overhead of handling
apache
and mod_jk for dynamic content is smaller then the difference of
apache
and
tomcat in serving images. I guess with current versions of tomcat the
overhead to apache and mod_jk is even bigger.
Hence, tomcat alone will be faster.
(Please also consider, that static content will mostly be taken from
the
browsers cache, whereas dynamic content needs to be received from
tomcat.
That means that the time won by using apache for static content needs
to be
a magnitude higher than the overhead of mod_jk. That's simply not the
case.)
Tomcat cannot do rewriting, that is correct, but it does not need to:
I use url such as:
/content/pages/test.htm
where content is mapped to my servlet.
The parameter is simply the rest of the url.
You could do:
http://localhost/site.do/books/architecture
and parse the rest of the url to
section = books
and
subsection = architecture
Simply map site.do to your servlet.
Reagrds,
Steffen

He said he had a hardware load balancer so the tomcat one is irrelevant. The main doc on the jakarta site is http://jakarta.apache.org/tomcat/tomcat-5.0-doc/cluster-howto.html, which explains what the clustering does but not much details about getting it working. To get the basic cluster working all you need to do is to uncomment the cluster section in your server.xml. The comments in there should give you some hints.

Re: Cluster Pure Tomcat with Hardware Load Balancer

Unless you want to opt for Tomcat's clustering feature, it would replication the session throughout all cluster nodes, which *could* solve your problem.

Multiple session timeouts in same web application
Hello: Can any one please explain the behaviour of session time out with Tomcat ? For example, if I specify a session time out of 30 minutes in web.xml and and then set session.setMaxInactiveInterval to 45 minutes in a page, then will it mean that only the page where I set it as 45 minutes will have a session time out of 45 minutes and all the rest of the pages will be having 30 minutes ? Or will the whole session will have a time out of 45 minutes after accessing the page where I set it as 45 minutes? Again, if I have multiple web applications with different session timeouts specified in respecitve web.xmls and single sign on enabled, then what will be the behaviuor ? ( Like, I accessed one web app page with timeout 15 min and went to a page in the second web app with timout set to 30 minutes, (all in the same session) then when will the first page will timout- after 15 minutes or after 30 minutes ?) In general, what is the optimum solution if i want different session time outs for pages in the same web application?

debug=0
disableUploadTimeout=true
compression=off
compressionMinSize=2048
noCompressionUserAgents=gozilla, traviata
compressableMimeType=text/html,text/xml /
[Assuming unix] - before running startup.sh - first set the JAVA_OPTS
environment variable to set 2 system properties for the jvm.
For example:
export JAVA_OPTS='-Dmy_port=8080 -Dmy_address=10.0.0.23'
On windows - see the FAQ on setting JAVA_OPTS. (for cygwin, the above command
works fine)

RE: Classes are reloaded automatically even when reloadable is not set
Hi, I'm using Tomcat 5.0.28 on Win98. I've created a very simple web app consists of just two java files: Does your webapp have a web.xml? Where are HelloServlet and Biz located? writer.close(); This is an aside, and irrelevant to this thread, but you shouldn't close the writer. Other things (response wrappers, filters) might want to do stuff that depends on the writer. A good rule of thumb is if you didn't create it, don't terminate it: you didn't create or open the writer, so don't close it.

RE: Upload File
If these questions are asked on the main list,

-Original Message-
From: Caroline Jen
I am trying to upload files from clients machine.
I understand that we must specify METHOD=post and
ENCTYPE=multipart/form-data in the FORM tag.
Would you please help me with a number of questions:
1. Once the client makes a selection from his/her PC, the
file name will appear in the text field. How do I 'save
the file name'?
within the servlet,
DiskFileUpload upload = new DiskFileUpload();
boolean isMultipart = FileUpload.isMultipartContent(request);
if (!isMultipart) {
logger.warn(userName(request)+File upload is not multipart);
ULerr = FORMNOTMULTIPART;
}
// Set upload parameters
...
try {
java.util.List items = upload.parseRequest(request);
// Process the uploaded items
String [] parms = gParms (items, request);
String [] gfileList = gFiles (items, request);
I have some plain textboxes as well as the list of files.
I'm re-working this piece;
currently
/**
*unwrap filelist, return as string array.
**/
public String [] gFiles(java.util.List items,HttpServletRequest request){
String[] retval=null;
java.util.Iterator iter = items.iterator();
int pos=0;
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();

String fieldName = item.getFieldName();
String fileName = item.getName();
String contentType = item.getContentType();
boolean isInMemory = item.isInMemory();
long sizeInBytes = item.getSize();
if (sizeInBytes == 0){
logger.info(userName(request)+ No files selected);
out.println(liNo files selected/li);
}else{ // file OK
pos +=1;
retval[pos] = fileName; // full path and filename
}
}//end of if is Form field
}// end of while more items
return retval;
}// end of gfiles()
That collects the list of filenames, prior to uploading them?
That should be sufficient to get you started.
The rest of my code is messed with the functionality I need?

2. Do I save what I download from the

No, its just java once you have the filenames. Just write them whereever you need them
to be.
3. Are there anything else I have to do to make file uploading work?

Root application in Tomcat
Hello, I have a problem with installing an application at root level in Tomcat. I have an application with a specified context: Context docBase=myApp path= workDir=work/Catalina/localhost/myApp I thought that leaving the path empty and removing the ROOT application was enough to install the application att root level so I can use http://localhost to reach the application instead of http://localhost/myApp. But this doesn't seem to work. When entering the root after deployment I end up in Directory Listing for / and all applications are shown. Is there a tutorial somewhere how to solve this or can anybody please help me with this.

RE: RE: Root application in Tomcat
Hi, I would also suggest adding a factory element to each ResourceParams in your d-test.xml file, and setting auth=Container for them to be complete. In addition, don't use Parameter unless you have to: that stuff can and should be included as context parameters in your web.xml. That approach is more portable and container-independent. But what you have is not illegal or invalid, the above are just suggestions. The server.xml also looks fine at a glance. So do you have a welcome-file for your webapp that matches what's in your web.xml?

What leading whitespace, and in what XML file?
I don't know whether this will help in your case,
but i meant the web.xml file located in the deploymant path:
{yourWebApp}/WEB-INF/web.xml
Seems like XML files are not allowed to begin with a whitespace.
Means this is wrong:

Problems with Tomcat 4.0.5
Hi I have developed a J2EE Application (1.3 specs), using Struts 1.1 Framework. It also uses Tiles, as integrated into the Struts Framework. The application is built on Tomcat 4.1.27, and works well on the development env. However, the production env /host uses Tomcat 4.0.5, and it's where it all plunges into problems. The exception is in JSP Custom Tags. My Site uses composite view pattern via Tiles, and the tomcat engine is failing to render the composite views successfully. Anyone has any idea? How to over come this issue? Host has a limitation and can't upgrade the tomcat. Is there a work around? Much appreciate your help.

RE: Cluster Pure Tomcat with Hardware Load Balancer
Thanks to all who sent a reply to my inquiry. I have seen and read (and am re-reading) the Tomcat Clustering HOW-TO, but that info seems very limited. I'm looking for real-life information from people who have actually set this up in a Windows 2000 environment, specifically (forgot to mention that before). I'm curious about how chatty my two clustered servers will become. I'd like to know what works the best for session replication: Multicast or TCP unicast? How about the implications of setting up Multicast on Windows 2000? There's more to all this than just uncommenting some blocks of the server.xml! From what I'm reading so far, it seems that Multicast is less 'chatty' on my network, but will require more CPU. I don't think that's going to be a problem, but I'm looking for some discussion about all this, whether its links to discussions, or real life experience (preferred). As for the load balancing deal: two non-clustered Tomcat servers works OK until throwing SSL (for secured shopping cart checkout) into the mix. There's lots of things that break session persistence in this scenario such as Microsoft IE 5+ browsers needing to renegotiate the SSL handshake every 2 minutes, and the megaproxy issue where ISPs such as AOL spray a user's browser requests through various proxy servers (all with different IPs). I run into dead-ends persuing each persistence maintenance option in load balancing, short of going the route of a SSL accelerator server or remaining on a single Tomcat server.

I deploy my app using a context configuration file located in: $CATALINA_HOME/conf/[enginename]/[hostname]/ I did notice that autoDeploy is set to true. So, maybe that is the issue? --- QM [EMAIL PROTECTED] wrote: On Mon, Oct 04, 2004 at 02:46:39PM -0700, Jeff Faath wrote: : However, what bugs me is the subdirectories under the : webapps directory can still be accessed even though : I can't find the configuration information for them.

Related to the above, it's likely a deployOnStartup tag in server.xml. I believe it's on by default, as a convenience for people who want to drop a set of apps/WARs into the webapps dir and have the changes picked up on Tomcat restart. Another solution -- though admittedly similar to your idea of deleting the other dirs -- is to use the $CATALINA_HOME vs $CATALINA_BASE setups to have one set of Tomcat binaries and several independent Tomcat instances. That way, the only webapps that exist for that instance are the ones you put there; any defaults/samples that ship with Tomcat are out of the picture. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] __ Do You Yahoo!?

RE: Class Not Found on Occasion but Class Exists and is Usually Found
Hi,
Does your CNFE (by the way, is it actually a CNFE or a
NoClassDefFoundError -- I think it's the latter, looking at the stack
trace, and the distinction is significant) occur when you've reloaded
your app? In other words, if instead of reloading you restart Tomcat
each time to deploy a new version of your app, does this error go away?
I'm asking the above because it might be related to
http://issues.apache.org/bugzilla/show_bug.cgi?id=28949, which has been
elusive.
What Tomcat version are you using?

RE: Cluster Pure Tomcat with Hardware Load Balancer
I've set up both windows and unix/linux clusters. Using multicast, it only send out the ping every few minutes so I can't imagine either a CPU or a network problem with this. The session replication is entirely down to how often the sessions are updated and how big they are. For me, getting the basic cluster up and running was just as simple as uncommenting the block, both in windows and unix although I can appreciate this may not be the case depending on if multicast is disabled on the machine. Further tweaking can obviously be done after this. One piece of advice I would give is to keep the sessions small, ie not several megabytes each, because you can run into some timeout issues. How many concurrent users are you expecting? And how often is are the sessions updated? -Original Message- From: MITCHELL TEIXEIRA [mailto:[EMAIL PROTECTED] Sent: 05 October 2004 19:27 To: '[EMAIL PROTECTED]' Subject: RE: Cluster Pure Tomcat with Hardware Load Balancer Thanks to all who sent a reply to my inquiry.

Re: Class Not Found on Occasion but Class Exists and is Usually Found
Sorry, you are right. NCDFE rather than CNFE. I should be more
careful. Usually I am. If I refresh the page, the class is found. I
am going to try the reloading. I restarted Tomcat and got the same
error. I am using a frameset, by the way. Sometimes one frame of the
frameset fails due to this and sometimes the other does. Rarely, never
I think, do both fail. I am using Tomcat 5.0.

I'm asking the above because it might be related to

elusive.

RE: Cluster Pure Tomcat with Hardware Load Balancer
Thanks for the reply - this is the type of user experience input I'm looking for!

Re: Cluster Pure Tomcat with Hardware Load Balancer
As for how often the sessions are updated, I don't know. I'd like it to be often enough that if a user was shifted he asked how often are your sessions updated? not the cluster :) The cluster will replicate changes, if any, to the other servers at the end of each request. the replication request is synchronous (default conf) so the data will be replicated by the time the user does his next request Filip - Original Message - From: MITCHELL TEIXEIRA [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: 'Dale, Matt' [EMAIL PROTECTED] Sent: Tuesday, October 05, 2004 3:19 PM Subject: RE: Cluster Pure Tomcat with Hardware Load Balancer Thanks for the reply - this is the type of user experience input I'm looking for!

Drops and Spikes in Tomcat responses
We are using a commerical servlet that seems to keep getting overloaded. We wrote a little script that monitors a number of things about the process - the number of open file descriptors, sockets, java threads, mysql connections, misc. hit types/second and memory sizes. We turned on -verbose:gc so that we could see the GC. I then did a tail of the two log files so that I could see the relationship between the two. Any time a full garbage collection takes place, a queue of connections builds up. At busy times, this is enough to make tomcat unable to ever catch up. If tomcat isn't 'too' busy, then a spike immediately follows. A sample can be seen below: == /var/log/tomcat/catalina.out == [GC 168312K-159078K(170540K), 0.0139380 secs] [GC 169766K-160496K(171308K), 0.0231370 secs] [Full GC * the full garbage starts here == tomcat_fd_and_threads.log == 2004-10-05 13:48:29 - 186 fds, 40 sockets, 79 jthreads,10 mysql con [28, 4, '16.2', '1.2'] hits/s 219868 186960 *** 28 max hits/sec *** 2004-10-05 13:48:39 - 186 fds, 40 sockets, 79 jthreads,10 mysql con [5, 1, '1.6', '0.0'] hits/s 219868 202660 *** 5 max hits/sec *** == /var/log/tomcat/catalina.out == * the full garbage collection finishes 14 secs later 160496K-84976K(171308K), 14.4078430 secs] [GC 95651K-86462K(170540K), 0.0303780 secs] [GC 97150K-87630K(170540K), 1.127 secs] [GC 98309K-88721K(170540K), 0.3796250 secs] == tomcat_fd_and_threads.log == 2004-10-05 13:48:50 - 92 fds, 40 sockets, 79 jthreads,10 mysql con [60, 2, '16.3', '0.5'] hits/s 219220 201996 *** 60 max hits/sec So before java started garbage collecting, Java was sitting at about max 28 connections / second processed. Only about 5 hits/second happened while java was garbage collecting (or immediately thereafter), and then the system processed about 60 hits/second to catch back up. Is there anything that I can do improve the scenario? I tried -Xincgc, but that didn't seem to help (it actually seemed to make it worse, although I don't have an accurate count of the load to know if was really the load on the server that was the problem). Is this typical for most servlets, or could there be a problem with the way it is written?

Tomcat service stopping w/o 'cause'
Have TomCat5 loaded on a Windows 2000 server as a service. At least twice a day it stops for no apparent reason. I've checked event viewer, Apache logs, Tomcat logs, Urlscan, just about every log I can find and see nothing in them that correlates with the times that TomCat stops. The only thing I can think of right now is Tivoli Storage Management Client is loaded and runs a schedule update job that fails about an 1 to 1 1/2 hours before TomCat stops. This job fails on many of my servers so I can't really implicate it per se and our Tivoli guy says that's normal - it is just running out to check to see if there is an updated schedule (we apparently don't update the schedule once set) and complains when the overloaded schedule server does not respond in time. So any leads on why TomCat5 is stopping? TomCat4 did not do this for what it is worth.

I'm hoping this is an easily answered question - is there a way with some simple Java or JSP code, or with a pre-built application to tell how many concurrent connections are going on my Tomcat instance? I'm running Tomcat 5.0.19 on Windows2000. I looked at JMeter, but that seems to be a test utility rather than a server management utility. What I'd like to see is something similar to the Windows Performance Monitor. Real-time updates every second or so. THat way when I need to restart Tomcat, I can tell how many peeved users there will be on the next click! :-) Thanks for any help MitchellT - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Search engine friendly URLs
I was talking bollocks (now i've tried it)
c:set var=link value=${fn:replace(link,'?','/')} /
c:set var=link value=${fn:replace(link,'','/')} /
works..
Ideally in a tag file like this,, /WEB-INF/tags/cleanLink.tag
%@ tag isELIgnored=false %
%@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %
%@ taglib uri=http://java.sun.com/jsp/jstl/fmt; prefix=fmt %
%@ taglib uri=http://java.sun.com/jsp/jstl/functions; prefix=fn %
%@ attribute name=link %
c:set var=link value=${fn:replace(link,'?','/')} /
c:set var=link value=${fn:replace(link,'','/')} /
${link}
..
and use the tag like this.
%@ taglib prefix=tags tagdir=/WEB-INF/tags %
c:url var=mylink value=/action.do
c:param name=one value=firstval /
c:param name=two value=firstval /
c:param name=three value=firstval /
/c:url
a href=tags:cleanLink link=${mylink} /click this/a
You may need tomcat 5 to do it..

The only problem then is generating the links. I think the original
question was posted on the struts group the other day and that he's
using html:link tags. I'd change these for jstl for the links.
so rather than
html:link page=/action.do ..
you'd use something like..
c:url var=link value=/action.do
c:param name=name value=somevalue /
.. and so on
/c:url
this will render to
/appname/action.do?name=somevalue
so now lets say you've set a boolean called cleanURL, this means you
can switch the functionality off if you want to deactivated urlrewrite
during development. An init param in web.xml i suggest would be the
best place, but for now lets set in the page.
c:set var=cleanURL value=true /'
c:if test=${cleanURL}
c:forTokens var=badChar items=?, delims=,
c:set var=cleanLink value=${fn:replace(link,badChar,'/'}'' /
c:set var=link value=${cleanLink} /
/c:forTokens
/c:if
a href=${link}Link/a
Once you've set urlrewrite filter up you'll want something like this.
rule
from/action.do/*/*/from
to type=redirect/action.do?$1=$2/to
/rule

Hi,
You can also do this with one (or more, if you want, depending on the

Hi
If you want to be able to scale your application, you need to be
able
to
move the static image handling out of tomcat to a separate web
server.
Using
Tomcat to handle both application chores and web serving chores will
limit
the overall scalability of your system.
I strongly disagree.
Tomcat is nearly as fast as apache in serving images.
So, yes, you can save a little time using apache, BUT remeber that
the
apache slows tomcat down. You need cpu-cycles for apache, for mod_jk
and
additionally for tomcat. Those cycles for apache and mod_jk are not
nessesary, since tomcat can work standalone.
So the question comes down to decide wether the overhead of handling
apache
and mod_jk for dynamic content is smaller then the difference of
apache
and
tomcat in serving images. I guess with current versions of tomcat the
overhead to apache and mod_jk is even bigger.
Hence, tomcat alone will be faster.
(Please also consider, that static content will mostly be taken from
the
browsers cache, whereas dynamic content needs to be received from
tomcat.
That means that the time won by using apache for static content needs
to be
a magnitude higher than the overhead of mod_jk. That's simply not the
case.)
Tomcat cannot do rewriting, that is correct, but it does not need to:
I use url such as:
/content/pages/test.htm
where content is mapped to my servlet.
The parameter is simply the rest of the url.
You could do:
http://localhost/site.do/books/architecture
and parse the rest of the url to
section = books
and
subsection = architecture
Simply map site.do to your servlet.
Reagrds,
Steffen

DIGEST Authentication in Tomcat 4 vs Tomcat 5
Can anyone point me to information concerning whether or not DIGEST authentication works in Tomcat 4 and/or Tomcat 5? I have only found conflicting information on the web as well as in several books. Is there a tutorial out there somewhere that would help me set this up? I have seen comments such as Container managed digest authentication is broken in almost all of Tomcat 4.1's realm implementations. Is this true? Have they been fixed in 5?

Delegating to default Servlet
Hi I want to archieve the following: I want to map everything to a special servlet that checks for permissions and a lot other things and finally invokes other servlets or modules of my system for dynamic content. however, I do not want to reinvent the wheel, so I would like to pass static requests after permission checking to the default servlet of tomcat. Mapping, permission analysing and all that is already done and no problems, delegating to my own servlets and modules also works as expected. However, how can I pass control to the default servlet of tomcat transparently, so that it does work as if it were invoked directly? Any hint would be great.

Re: Delegating to default Servlet
How about a Filter instead? Otherwise - you can use getNamedDispather() get the default servlet. -Tim Steffen Heil wrote: Hi I want to archieve the following: I want to map everything to a special servlet that checks for permissions and a lot other things and finally invokes other servlets or modules of my system for dynamic content. however, I do not want to reinvent the wheel, so I would like to pass static requests after permission checking to the default servlet of tomcat.

Hello Kaleb, This sounds like an opportunity to break out with a profiler. That will pinpoint exactly where methods are being held up, etc. You've done some detective work that points to GC problems, and that may very well be it, but a profiler would help you hunt down specifically what's going on. For example, a profiler would tell you what count of a given object is on the heap at the time the app starts to crawl. There are several tunable params with a Java app -- heap size, thread stack size, OS-level properties -- but it's often best to start with a profiler. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

problem redeploying war files on tomcat 4.x
Hi. I have an existing application deployed as a war file. When I update the war file, stop and start tomcat again, the war file is not re-expanding over the old deployment. I have set the permissions to 777 so it should not be a permissions issue. It works if I delete the existing directory it expands into, then restart tomcat, however that's not practical for a production environment. Anyone have any ideas for me? --Dan Supporting configs: xml fragment in webapps: !-- BEGIN CONTEXT -- Context path=/bar docBase=/foo/bar.war debug=0 reloadable=true crossContext=false privileged=true /Context !-- END CONTEXT -- server.xml Host name=foo.com debug=0 appBase=/foo unpackWARs=true autoDeploy=true deployXML=true liveDeploy=true The odd thing is that the logs indicate it's writing the files, but they don't actually get updated. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Classes are reloaded automatically even when reloadable is not set
From: Shapira, Yoav [EMAIL PROTECTED] Does your webapp have a web.xml? Where are HelloServlet and Biz located? Sorry that I can't seem to reproduce this. Maybe it was indeed marked as reloadable in server.xml but later I deleted the context and created a new one in its own .xml file. This is an aside, and irrelevant to this thread, but you shouldn't close the writer. Other things (response wrappers, filters) might want to do stuff that depends on the writer. A good rule of thumb is if you didn't create it, don't terminate it: you didn't create or open the writer, so don't close it.
