tomcat-users.xml gets erased
We are running a tomcat webapp which allows the remote administration of a
Solaris machine via a http interface.
Access control is managed using the default MemoryRealm implementation
(using tomcat-users.xml to store users and roles).
The webapp allows changing various settings on the machine (including
editing and saving of the tomcat-users.xml file)
We're having the following problem:
From time to time our tomcat-users.xml file is erased (it is replaced by a
file only containing the following:
tomcat-users
/tomcat-users
).
So far we have not been able to reproduce this behaviour (it has happened
both after a tomcat restart and while running normally).
I have a feeling this has to do with the behaviour of the
org.apache.catalina.users.MemoryUserDatabase class.
In our code, when a user logs in, we access this class to retrieve the user
roles assigned to this particular user, like so:
MemoryUserDatabase userDatabase = new MemoryUserDatabase();
userDatabase.open();
User user = userDatabase.findUser(USER_ID);
userDatabase.close();
...
If login is successful, the user object is stored in the user's session
context. For access control, a user's roles are retrieved using:
Iterator iter = user.getRoles();
while (iter.hasNext()) {
Role aRole = (Role) iter.next();
if (aRole.getName().equals(REQUIRED_ROLE_FOR_ACCESS)) {
return true;//allow access
}
What could be the cause of this problem? I have seen a similar post
(http://archives.real-time.com/pipermail/tomcat-users/2003-March/103924.html
) before, but I have not found an answer so far.

custom error pages
Hi, I,m using tomcat 5.0.27 and am trying to show custom error pages. I added a couple of errorpage tags to my webapps web.xml and the /conf/web.xml in the tomcat installation dir. error-page error-code500/error-code location/error/error.html/location /error-page and after telling internet explorer not to use userfriendly errorpages it shows the errorpages defined in my webapp when I try to access an nonexisting url inside my webapps context (e.g. /my_existing_webapp/does_not_exist.html) and shows the default errorpages when I go to an url that does not exist at all (e.g. /non_existing_webapp/whatever.html), that is after I copied my error files into the ROOT context. But I cant get it to work when my webapp is defined but not running. What I did was this: - start tomcat - goto the manager webapp - shutdown the webapp with custom errorpages - enter a valid url for that webapp in the browser. Now I get the standard tomcat errorpage. So I did a little debugging and found that when tomcat stops a webapp, it preserves the context it just strips it from all but the name (well almost). So my custom defined errorpages are gone and because tomcat did find a context it wont use the errorpages defined in the default web.xml (or root context) but instead goes for the tomcat errorpage. I thought I could outsmart tomcat, so I made a little lifecylelistener and container listener so I would get notified of the removal of my errorpages and then put them back in. Even though that works, tomcat still shows its own errorpages because further down the line it tries to get a requestdispatcher from the context (which was stripped) to forward the request for the errorpages. And there it fails offcourse. Now we get to the question(s) :) - does anyone know what else needs to be preserved in the context in order to deliver a valid requestdispatcher (there is a lot that gets removed, and its probably quicker to get an answer from you guys then painstakingly use trial and error) - or perhaps a better question could you guys (developers) make the next (nightly) release so that it tries to get errorpages from the default web.xml (root context) before showing the tomcat errorpage. Because its more then likely my little hack is going to break something if I get it to work. If no one can or bothers to answer the first question I can live with that, I've surrendered :) but I would like to see the 2nd request/ feature to happen.

Can anyone enlighten ? 2) Whats the best configuration mechanism for my servlets? I think its better to add the the servlets to my com.mycompany.myapp package (or?), BUT, is it a security flaw when I set in my app, the url-pattern begininning with /servlet/* (see below example).

Re: SSL problems with commercial X509 certificates and jks - solution
Hi, I have finally found a solution to the problem of using commercial certificates and running tomcat in https mode. As this seems to be a common issue for people using tomcat and 3rd party certs, I have provided the information below - might save someone else some time! (I have translated the solution found at http://listes.cru.fr/www/arc/pki-fr/2003-04/msg4.html) *** Prior to starting: Ensure that there is a hostcert.pem and hostkey.pem and that the hostcert.pem starts and ends with --BEGIN CERTIFICATE - and -END CERTIFICATE -. If it contains any other information then create a copy of the .pem file, delete any other lines and use this copy to carry out the steps below. The following steps should be followed to configure Tomcat for Https communication using 3rd party CA certificates. 1.Follow ONLY the 'Edit the Tomcat Configuration File' section in the Jakarta Project Tomcat SSL Configuration HOW-TO located at http://jakarta.apache.org/tomcat/tomcat-4.0-doc/ssl-howto.html. 2.Import CA root certificate into Tomcat cacerts store. keytool -import -keystore $JAVA_HOME/jre/lib/security/cacerts -file caRoot.pem. This is the system wide CA certificates store and contains entries for other CA such as Verisign and Equifax. 3.Create the java keystore used by Tomcat. This is located at $HOME/.keystore if the file doesn't already exist it will be created in the process. The first step is to generate a certificate in pkcs12 format by combining the host's key and certificate. openssl pkcs12 -export -inkey hostkey.pem -in hostcert.pem -out host_name.pkcs12 The next step is to read the pkcs12 file into the keystore. To do this a java class taken from Jetty is used. Download Jetty (if required) and locate the PKCS12Import.java file. This needs to be compiled and then run using java -classpath org.mortbay.jetty-jdk1.2.jar PKCS12Import host_name.pkcs12 $HOME/.keystore ( java classpath class file pkcs12 cert keystore location ) When asked for the input keystore password this is the certificate password used in the step above. The output keystore password is the password of the .keystore, 'changeit'. This puts the host certificate and key into the keystore with an alias of 1. To rename the alias the following steps are required: keytool -keyclone -keystore .keystore -alias 1 -dest host_name Delete the alias 1 from the keystore using: keytool -delete -keystore .keystore -alias 1 (These steps are not obligatory) Create the chain of certificates. Concatenate the host certificate file with the CA root file. cat hostcert.pem caRoot.pem certchain-host_name.pem Generate a pkcs7 file which contains this chain: openssl crl2pkcs7 -nocrl -certfile certchain-host_name.pem -outform DER -out certchain-host_name.pkcs7 Import this chain to the keystore keytool -import -alias host_name -trustcacerts -file certchain-host_name.pkcs7 -keystore .keystore Check the content of your keystore keytool -list -v -keystore .keystore This should contain the entry of type keyEntry, which is a chain of certificates. If using jakarta-tomcat-4.1.27, a known bug exists which results in tomcat throwing a fatal error after two hits with https. This bug is documented and discussed with the necessary information to fix this issue at http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22701. Restart tomcat and open https://host_name:8443/ in your browser. Hope this helps!

Downloading an applet over https
Hi, I have a java applet that I use for signing files before they are posted to my tomcat server. The applet is accessed through a simple JSP page. Since the applet must have access to the client file system, it is signed by my keystore. I can successfully sign files over http, however, some problems occur when I migrated over to https, particulary when using client authentication. Strange things occur when the applet is accessed over https with client authentication. The catalina.out logs write this message whenever the page is accessed: 04-Aug-2004 19:05:05 org.apache.tomcat.util.net.TcpWorkerThread runIt SEVERE: Remote Host /152.78.69.24 SocketException: Broken pipe 04-Aug-2004 19:05:05 org.apache.tomcat.util.net.TcpWorkerThread runIt SEVERE: Remote Host /152.78.69.24 SocketException: Broken pipe The java console on the client reports similar problems, but in a verbose manner: java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at com.sun.net.ssl.internal.ssl.OutputRecord.writeBuffer(OutputRecord.java:282) at com.sun.net.ssl.internal.ssl.OutputRecord.write(OutputRecord.java:271) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.writeRecord(SSLSocketImpl.java:663) the same exception repeats 17 times! load: class SignFilesApplet not found. java.lang.ClassNotFoundException: SignFilesApplet at sun.applet.AppletClassLoader.findClass(AppletClassLoader.java:164) at java.lang.ClassLoader.loadClass(ClassLoader.java:289) Caused by: java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at com.sun.net.ssl.internal.ssl.OutputRecord.writeBuffer(OutputRecord.java:282) at com.sun.net.ssl.internal.ssl.OutputRecord.write(OutputRecord.java:271) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.writeRecord(SSLSocketImpl.java:663) I've heavily abbreviated these exceptions to ease the reading.

Re: ajp over ssl
Problem with IPSEC / ssh tunnels between two machines is that if someone compromises one machine, then you've made their life 500% easier getting to the next one. Good stuff to connect your home LAN to office LAN, but I wouldn't.. I had trouble with the same thing, and the easy solution I found was to ReverseProxy apache to Tomcat and in the proxy directive to simply say pass it on to https://, and configure Tomcat with it's keystore and hey presto.

RE: JMS with tocmat
Hi, Wow, I was actually just trying to figure out how to hook up a Tomcat system to a remote jBoss JMS queue. Is there good documentation on how to accomplish this on the OpenJMS site? Why would the OpenJMS site have any JBoss documentation? It has good docs for how to connect and use an OpenJMS server. The process would be the same for all such servers though: - Download the JMS client jar for your JMS server and put it in your webapp's WEB-INF/lib directory. - Write your code to explicitly specify the connection factory in the InitialContext environment. This will be an implementation class specific to your JMS server, e.g. weblogic.jndi.WLInitialContextFactory for Weblogic, org.exolab.jms.jndi.InitialContextFactory for OpenJMS, org.jnp.interfaces.NamingContextFactory for JBoss. - Specify the server name and port also in the InitialContext environment. That's it, the rest is like any JMS tutorial: do a JNDI lookup for your connection, then your queue/topic, get a session, etc. Yoav This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

RE: Compile all JSPs on startup
Hi, Is there a configuration setting for Tomcat to it recompile all JSP files at start up? No. You can precompile your JSPs as noted at http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jasper-howto.html#Web%20 Application%20Compilation and other locations. If this is the only way, how and where do you specify startup servlets in tomcat? And what if I want to enable/disable this feature on startup -- what's best approach for setting the flag in tomcats config files? You might want to read the Servlet Specification at some point. You specify startup servlets in Tomcat the way you do in all other servlet containers: by adding load-on-startup[number]/load-on-startup to their declaration in your web.xml file. Since you would code this servlet, you can handle enable/disable of this precompilation however you want. A likely choice would be a simple servlet init-parameter, also in web.xml. This is not specific to Tomcat and would not go in Tomcat's configuration files.

Session Pooling?
Hi All, This may have been answered elsewhere in the past but I'm struggling to find it if it has - though please point me in the direction of past answers if that's the case. I'm trying to understand how a single instance of Tomcat manages sessions. Is there any pooling/recycling of sesssion objects or are they created/destroyed as required? If they are pooled, is the size of this pool configurable? Also where can I find some good documentation on managing sessions across a cluster or load balanced instances? Does anyone know of a practical limit for the number of concurrent connections Tomcat can cope with on a reasonably out of the box Redhat installation (obviously file descriptor limits aside)? Any info you can supply would be much appreciated (I also need to find this out with some urgency) Thanks in advance Mike --- Outgoing mail is certified Virus Free.

Re: java.lang.OutOfMemoryError
In addition to Yoav's comment, you may also want to check on the number of sessions that get created. I know that JRun3 didn't create a session when it wasn't necessary to do so, Tomcat 5 (as per servlet spec.) always creates a session. Typically webcrawlers don't 'do' cookies, so a new session gets created for each request. This can of course have a significant effect on memory.

classloader hangs
Hello, I am writing a class to be deployed with the Tomcat SOAP web app (I'll call this class A). It uses a URLClassloader to load classes from a directory (i call them modules). I initialize my class loader with URLClassLoader initialLoader = new URLClassLoader(urls, Thread.currentThread().getContextClassLoader()); This worked fine for a while. However, when I decided that my class A needed to have a package statement (I wanted to put it in a jar file along with some libraries for easy distribution), I was very much dismayed when the class loading did not work. Yet the strange part is that it is not the usual NoClassDefFound exception, instead the entire program just seems to hang upon trying to load one of the modules. I am very dismayed as what was once working code is now almost useless. Chances are, I'm just making a stupid mistake, however if anyone could please help me I would be grateful. Thanks, Ben P.S.

hi; threre are some thread regarding this but i did not find a definite answer. does tomcat has a UserTransaction implementation ready to use out of the box? or do i have to download JTOM or something similar in order to use a JTA UserTransaction. i use tomcat 5.0.25. when i lookup java:comp:UserTransaction i get an exception below: javax.naming.NamingException: Cannot create resource instance at org.apache.naming.factory.TransactionFactory.getObjectInstance(Transa ctionFactory.java:145) at javax.naming.spi.NamingManager.getObjectInstance(NamingManager.java:3 01) at org.apache.naming.NamingContext.lookup(NamingContext.java:838) so i guess that something is binded under this name in JNDI and flow goes to the trasactionFactory so what the deal here? any help is appreciated. thanks in advance.

RE: classloader hangs
Hi, If you get a thread dump of the JVM while it's hanging, what does it show? The URLClassLoader is intended for use within Tomcat. It's nice that you have a program using outside Tomcat, but it's not that meaningful for comparison testing. The ClassLoading scheme and hierarchy inside a servlet container is significantly different from the one inside a console Java application. NoClassDefFound is not an exception, it's an Error. It's different from ClassNotFoundException. And that difference (see the JavaDoc for both) may be the root of your problem.

RE: JTA tomcat
Hola, Version 5.0.26 (and better yet, 5.0.27 which is stable) fixes the TransactionFactory bug you're seeing. So update to 5.0.27 if you can.

RE: Urgent attention needed to solve mysterious SocketException error
Are you running tomcat stand alone ? One possible cause is that tomcat is trying to open a socket where nobody is listening. (Invalid argument or EINVAL is a common error returned by all kind of socket operations in this case) Without more of the stacktrace it's difficult (at least for me) to say anything about the context where the problem is occuring. -Original Message- From: Adrian G.

Thanks. -Message d'origine- De : LERBSCHER Jean-Pierre [mailto:[EMAIL PROTECTED] Envoyé : mardi 27 juillet 2004 19:07 À : '[EMAIL PROTECTED]' Objet : [jaas integration between tomcat/weblogic] Hi, I would like to make EJB-calls from Tomcat to EJB in Weblogic in secure environment (using j2ee roles). I configure a custom JAAS Realm that uses client side LoginModule connecting to WLS (weblogic.security.auth.login.UsernamePasswordLoginModule). I put weblogic.jar into common/lib directory and my login module classes in common/classes. I configure webapp context like this : Realm className=org.apache.catalina.realm.JAASRealm appName=Sample userClassNames=weblogic.security.principal.WLSUserImpl roleClassNames=weblogic.security.principal.WLSGroupImpl debug=99/ I grant all permission (for test only) in Catalina.policy. And I run Catalina with -security option. At this stage tomcat uses login module (and weblogic authentification provider) to authenticate the user. Everything works fine. The subject build by weblogic is used to create a GenericPrincipal used internally by Tomcat. My problem is that I need to use weblogic security api to propagate implicitly the subject when i call the ejb component with the security data provided by weblogic authentification provider (the subject). First I try to run Tomcat with the security option and the permission, enables me to get the tomcat subject (for example like this javax.security.auth.Subject mySubject = javax.security.auth.Subject.getSubject(java.security.AccessController.getCon text()); ) and call the weblogic security api with that subject. However the Tomcat GenericPrincipal is not serializable and I get an exception [java.io.NotSerializableException: org.apache.catalina.realm.GenericPrincipal]... Secondly I try to rebuild the weblogic subject with the subject generated by javax.security.auth.Subject.getSubject(java.security.AccessController.getCon text()); I get an java.lang.SecurityException: [Security:090398]Invalid Subject: principals=[my_username] exception generated by weblogic. It seems obviously that there are problems of integration! My suggestions are to keep a trace of original subject (for example in session with a specific key) or in a classe that is accessible to application classes (and not dependent on tomcat specific api). Do you have any others suggestions ?

Realm configuration not working
Greetings! I've recently decided to take advantage of Tomcat's authentication mechanism, however, it doesn't appear to be working for me. I've configured a Realm in my context (through the admin tool). It is a DataSourceRealm. When I've tested everything, I keep getting pushed out to the error page that I've configured in my login settings. Since I couldn't figure out what was going on when I screwed up the debugging levels, I grabbed the source and started stepping through it in my debugger. Here's where it gets interesting. When FormAuthenticator.java gets the Realm to authenticate against: Realm realm = context.getRealm(); The Realm that is returned is Tomcat's global UserDatabaseRealm - not my DataSourceRealm. At this point, its no wonder that the authentication isn't succeeding!! Why isn't Tomcat using the Realm configured in the context?! This is on Tomcat 5.0.27 under jdk 1.4.2.

Strage Behaviour - Tomcat Memory Leak
Hi, I was doing an evaluation of JProfiler in order see the improvements did since the last time I used it. I has a feature (like other profilers) that shows the heap usage in real time. As I always do, I have installed a new copy of tomcat, with NO changes. I have just unziped it into a directory (by the way, I am using winXP, J2SDK1.4.2_05, JProfiler 3.1 and tomcat 4.1.30/5.0.25). So I started JProfiler, that automatically starts tomcat (I have tested it against 4.1.30 and 5.0.25 - same behaviour), and I also started the heap monitor (that JProfiler calls VM Telemetry). What I saw, IMHO, is very strange: time to times (around every 30 minutes) the heap is totally filled, and the garbage collector runs. So the graph looks like a saw: /| /| /| / / | / | / | / / |/ |/ |/ What is strange, is that I does't touch tomcat. I just start it. Nothing is running under it (except the default applications: manager, examples, etc Anyway, I have cleaned the server.xml and webapps, removing the manager, admin and examples app. Same bahaviour again). IMHO, the heap usage should be a flat line if nothing is running under tomcat. Something like (the initial increase is due to tomcat startup) this: /-- / / My conclusion, is that OR tomcat has a huge memory leak, OR JProfiler isn't reliable.

Re: Tomcat Realm-- pasword encryption servlet location in a webApp
Encryption: There is only one way to encrypt passwords if you are not using SSL. That is to use Paj's JavaScript module available here: http://pajhome.org.uk/crypt/md5/ Although the Tomcat Realm does have an MD5 flag which you can set to encrypt the passwords being sent to it this is too late as the passwords have already been sent in the clear over the internet to your server. The only use for this is when you are accessing a server on which the passwords are stored in MD5 encrypted format and you don't care about the network. You may also be told that you can use a Digest login instead of a Form login or Basic Login but again you have a problem: Digest logins are only available in IE so if you know all your users are definitely only using IE then go ahead, it will be doing the same job as the JavaScript i.e. encrypting before sending down the wire. In order to encrypt the passwords in the first place you can use Java1.4's java.security.* package or you can use Catalina's org.apache.catalina.realm.RealmBase which can be used at the command line thus: C:\java org.apache.catalina.realm.RealmBase -a MD5 mypassword or you can use the JavaScript. If you have the passwords in an Oracle Database you can also use the Oracle Function DBMS_OBFUSCATION_TOOLKIT.MD5() by writing an oracle Function something like this: CREATE OR REPLACE FUNCTION get_md5 (plaintext IN VARCHAR2) RETURN VARCHAR2 IS test VARCHAR2(16); BEGIN test:=DBMS_OBFUSCATION_TOOLKIT.MD5(INPUT_STRING=plaintext); RETURN test; END get_md5; / Note: using a function like this you can create a view of the passwords table in your database which would mean that though your passwords appear hashed to Tomcat, they are actually still visible to you! The servlet invoker /servlet/* If you are adding the servlets to your web.xml file then you do not need to use the servlet invoker anywhere and hence do not need to call it using /servlet/. Whether or not you add the servlets to the same package is a programming decision which has to do with what the servlets do and whether they do the same thing as the other classes in that package. This has no bearing on the administrative decisions of how to keep the server secure. Hope that all helps.

Re: Strage Behaviour - Tomcat Memory Leak
I've used JProfiler in the past and I found it somewhat unreliable, since it is pretty heavy weight. I should say it was based on a half dozen tests using JProfiler and not a scientific evaluation. it was the free eval version a couple years back. I find optimizeIt more reliable for me and a little less heavy weight. I've use OptimizeIt in the past and tomcat without any requests shows flat memory usage. in other words constant. peter On Thu, 5 Aug 2004 13:39:44 -0300, Roberto Rios [EMAIL PROTECTED] wrote: Hi, I was doing an evaluation of JProfiler in order see the improvements did since the last time I used it.

From: Peter Lin [mailto:[EMAIL PROTECTED] Subject: Re: Strage Behaviour - Tomcat Memory Leak I've use OptimizeIt in the past and tomcat without any requests shows flat memory usage. in other words constant.

RE: Strage Behaviour - Tomcat Memory Leak
As Yoav points out, this is quite normal. I also run JProbe and if you just leave it alone, very small memory usage is made and at regular intervals the GC will jump in, producing your saw tooth (since the GC will only jump in when it really thinks the heap needs clearing out is why it gets quite high). Also when you say the heap is totally filled I don;t think you mean that the total memory available to Tomcat is filled, e.g 128-512MB or whatever. What you mean is that the heap used is filled and I bet that heap size is actually only about 7Mb or so if as you claim it is just a startup of Tomcat. Therefore it is quite possible that it looks alarming but it is not really.

RE: custom error pages
Hi, Of course, you could write a customized Connector to do this. Or you could have an entirely separate server dedicated to error messages and forward there from your custom connector. Or whatever. If you want to go as far as to write a custom Connector to do this, you could do a lot of other things. My answer was in terms of current tomcat code/features, there's no configurable setting to do this. One of the main benefits of an open source server with the Apache license is that you can do whatever you want with it...

Re: classloader hangs
Hello, I know this is naive of me, but how does one get a thread dump of the JVM? Anyway, as for the other comments, do I have to do something different to use URLClassLoader under Tomcat than I do in a console application? I kept getting this same problem under Tomcat before when I was creating URLClassLoaders without specifying Thread.currentThread().getContextClassLoader() as the parent, but by adding it, the error went away. It just seems strange that code that worked fine stopped working when the only change I made was to insert a package statement. As for the NoClassDefFoundError vs ClassNotFoundException, I do have exception handling code around the loadClass method, and it is not reporting anything, and to the best of my knowledge, an error should terminate the JVM right?

The URLClassLoader is intended for use within Tomcat. It's nice that you have a program using outside Tomcat, but it's not that meaningful for comparison testing. The ClassLoading scheme and hierarchy inside a servlet container is significantly different from the one inside a console Java application. NoClassDefFound is not an exception, it's an Error. It's different from ClassNotFoundException. And that difference (see the JavaDoc for both) may be the root of your problem.

How? thanks, Samuel. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: classloader hangs
if you've got it running in a DOS window (which you might want to do, for just this purpose), you can try either the Pause/Break key, and if that doesn't do it, try 'Cntrl-C' in the DOS window. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, August 05, 2004 4:10 PM To: Tomcat Users List Subject: Re: classloader hangs On Windows XP? :-( (my employer doesn't enjoy linux) Send a SIGQUIT to the JVM process. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
special chars : é è ê ï etc...
Hi all I have troubles with accent. Sometimes, tomcat displays the accent with a ? instead. I think it is a java configuration pb. I have the version 5.0.27 and this is what I use to launch tomcat : export JAVA_OPTS=-server export CATALINA_OPTS=-Djava.awt.headless=true -Dfile.encoding=UTF-8 -Ddcm.home=$installDir -Dbuild. compiler.emacs=true -Djava.library.path=$installDir/lib -Xms256m -Xmx256m -XX:PermSize=128m -XX:MaxP ermSize=128m Note that $installDir is a custom dir with no importance Thanks. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Thai, Are these characters encoded directly in the JSP or loaded via message bundles? How are they being output to the browser? What encoding are you using for the output? UTF-8? The default (ISO-8859-1) will not display these characters correctly.

Jspc and Taglibs
I made several measure, had a look to the generate code by Jspc. It is clear that Taglibs reduce the performance (memory, speed) of your server. Speed because the first time access is longer and memory because a pool system is there to make the next pages being displayed quicker. So, as a developper, I'm wondering if the Tomcat gurus are aware of all of that and if they are taken some actions. For example, I think that it is a (good or bad ?) idea to try to transform the taglibs instructions into scriptlets (like preprocessing in C) and then compile the JSP pages. I am using JSTL recently and I am happy because my JSP are now scriptlet-less BUT the performance are hit. I tried a few days to make a preloading system to fill the different pool, but it not seems possible. Anyway, I'll keep JSTL because it is a good choice for maintaining easier your JSP. I think there are a few steps to make all that very powerfull. What do you think ? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Recursion in JSP
Hi Andrew,
If what you need is to call JSPs recursively, MicroNova YUZU tag library
(http://sourceforge.net/projects/micronova-yuzu) supports recursion
passing arbitrary (non-string) objects using m:call and m:param tags
like this:
m:param var=input/
tag:tree
c:forEach var=child items=${input.root.children}
m:call path=dfs.jsp
m:set property=root value=${child}/
/m:call
/c:forEach
/tag:tree
Hope this helps.
Best Regards, Makoto Nagata

Does anyone know if I am able to use recursion to traverse a tree but then to use a
tag inside the recursive method? If that was unclear, I want to know if I can do this:
%!
void dfs(Node root){
%
tag:tree
%!
Vector children = root.getChildren();
for(int i=0; ichildren.size(); i++){
dfs((Node)(children.elementAt(i)));
}
%
/tag:tree
%!
}

Thanks,
