Re: FW: tomcat hangs with error msg-All Threads are Busy.....
I think you should not use synchronized sections / mutex to get informations from client. Common policy in using mutex is to keep them as little time as possible and do only the critical work inside the exclusive part.This is to prevent long waiting queues and ... things like that :) Ajit Narayanan wrote: You are right! The code does implement a mutex() part. But the problem lasted for 7 days untill the server was restarted manually. There were about 15 threads which were found to be in locked state.And for all these days tomcat was not accepting any requests.

Re: Tomcat 5.0 : how to redirect a 401 error to a specific page
See section 10.4.2 of http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html You have to understand the page user see when he hit cancel has been send by tomcat before the user hit cancel. This is the page which is shown to user to indicate him he requires authentification. If you want to customize the layout of this page, use the error-page error-code location way, but do not, in you page send any redirect as it will break authentification mecanism (the browser won't get it's 401 header and thus won't show the http auth dialog to user). Francis Galiegue a écrit : Hello, Our webapp runs with Tomcat 5, Apache 2.0.46 from RHEL3, Tomcat 5.0.27 from JPackage, and communicate via mod_jk 1.2.6. Here's the problem we face: our webapp sends notifications by email, with a link to a JSP requiring a classical HTTP authentication dialog. This same page is used for the login form into the application, and its behaviour is controlled by the parameters passed to it. When the user DOES NOT submit any information (ie, it presses Cancel on the dialog box), Tomcat shows its 401 page. I've tried the following: * add an ErrorDocument directive to Apache config: no go; * add an error-page tag with error-code and location into the web-app section of WEB-INF/web.xml with the location pointing back to the same page, with no parameters: no go either... It's even worse in this case, since the Tomcat 401 page shows directly, the HTTP auth dialog doesn't even appear. I haven't tried _both_ at the same time, but I believe it wouldn't be the solution. As I'm not really fluent with Apache/Tomcat and webapps, I don't know where I should look at to solve the problem. Any hints would be more than welcome!

Re: Java process segfaulting and using 100% CPU
There are several ways to find out where tomcat is spending all it's cpu time 1) when it's a 100% CPU eating time issue a few stacktraces at a 10 or 20 seconds interval. then compare all those trace and try to find a stacktrace which is recurrent. This is clearly not easy and might require quite a few hours of analysis to point a list of reccurrent working area during the various dumps. If you have an endless loop of a very slow process, it should be present in a thread for all dumps. 2) check twice you don't have memory consumption problems. We noticed a few time here that tomcat behaving very slowly is a prefail warning of a memory outtage (The garbage collector becomes aggressive). So increase max memory and max permergensize. (You should get out of memory errors anyway in the end if this is the case 3) Use a profiling tool to get reports on CPU usage by various areas of code. When it comes to debugging CPU usage or memory leaks, profilers are very usefull. The drawback is you have to run your tomcat in a profiled environnment which will take note of execution time of all your method calls. If you can't reproduce your problem on a test server ,that mean you need to profile your production server, but profiling tomcat render it about 4 to 10 times slower, depending on the profiler, the memory on server, etc. 2 points in stack trace worth checking, i noticed 2 threads are not in sleep state and have a similar part in stack trace, check twice if there is no endless loop around at br.gov.mds.suasnob.data.pessoafisica.PessoaFisicaData.getPapelList( PessoaFisicaData.java:185) at br.gov.mds.suasnob.data.pessoafisica.PessoaFisicaData.getPapeis( PessoaFisicaData.java:160) partial traces: http-8080-Processor7 daemon prio=1 tid=0x08b6c9f8 nid=0x5048 runnable [0x6f627000..0x6f6296c0] at org.hibernate.event.def.AbstractVisitor.processValue( AbstractVisitor.java:102) at org.hibernate.event.def.AbstractVisitor.processValue( AbstractVisitor.java:64) at org.hibernate.event.def.AbstractVisitor.processEntityPropertyValues( AbstractVisitor.java:58) at org.hibernate.event.def.DefaultFlushEntityEventListener.onFlushEntity (DefaultFlushEntityEventListener.java:198) at org.hibernate.event.def.AbstractFlushingEventListener.flushEntities( AbstractFlushingEventListener.java:190) at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions (AbstractFlushingEventListener.java:70) at org.hibernate.event.def.DefaultAutoFlushEventListener.onAutoFlush( DefaultAutoFlushEventListener.java:39) at org.hibernate.impl.SessionImpl.autoFlushIfRequired(SessionImpl.java :711) at org.hibernate.impl.SessionImpl.prepareQueries(SessionImpl.java:895) at org.hibernate.impl.SessionImpl.getQueries(SessionImpl.java:885) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:834) at org.hibernate.impl.QueryImpl.list(QueryImpl.java:74) at br.gov.mds.suasnob.data.pessoafisica.PessoaFisicaData.getPapelList( PessoaFisicaData.java:185) at br.gov.mds.suasnob.data.pessoafisica.PessoaFisicaData.getPapeis( PessoaFisicaData.java:160) at org.hibernate.engine.ActionQueue.sortCollectionActions( ActionQueue.java:292) at org.hibernate.event.def.AbstractFlushingEventListener.flushCollections( AbstractFlushingEventListener.java:244) at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions (AbstractFlushingEventListener.java:71) at org.hibernate.event.def.DefaultAutoFlushEventListener.onAutoFlush( DefaultAutoFlushEventListener.java:39) at org.hibernate.impl.SessionImpl.autoFlushIfRequired(SessionImpl.java :711) at org.hibernate.impl.SessionImpl.prepareQueries(SessionImpl.java:895) at org.hibernate.impl.SessionImpl.getQueries(SessionImpl.java:885) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:834) at org.hibernate.impl.QueryImpl.list(QueryImpl.java:74) at br.gov.mds.suasnob.data.pessoafisica.PessoaFisicaData.getPapelList( PessoaFisicaData.java:185) at br.gov.mds.suasnob.data.pessoafisica.PessoaFisicaData.getPapeis( PessoaFisicaData.java:160) at sun.reflect.GeneratedMethodAccessor1697.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke( DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at ognl.OgnlRuntime.invokeMethod(OgnlRuntime.java:491) at ognl.OgnlRuntime.callAppropriateMethod(OgnlRuntime.java:785) at ognl.ObjectMethodAccessor.callMethod(ObjectMethodAccessor.java:61) ..

Re: Java process segfaulting and using 100% CPU
Leon Rosenberg a écrit :
I don't know it depends on your implementation of hashCode() method.
Are you using 1.5?
static int hash(Object x) {
int h = x.hashCode(); -- your programm is here
h += ~(h 9);
h ^= (h 14);
h += (h 4);
h ^= (h 10);
return h;
}
I think chances are low that the you see threads in this method often.
Would you mind checking the hashCode() method implementation of the
objects you put in the map?
Maybe someone programmed some kind of very-cool-hash-code-optimization
and got an infinite loop.
False :)
Please note the thread dumps tells the Thread http-8080-Processor56 is in
java.util.HashMap.hash(HashMap.java:264)
not in something like com.company.veryCoolClass.hashCode();
as you said, the program is here : int h = x.hashCode()
that mean it is either in the step of putting the value from registers to h ,
either in precall of x.hashCode(). In no way is it currently running
x.hashCode() :)
Please also note, chance to get Threads in there are not so low when you play a
lots with Hashmap :)

Re: Java process segfaulting and using 100% CPU
Hi,
or other processes may end up using 100% CPU as well and presenting the
same behavior while on strace
If you mean also non java processes have similar problems, randomly, i
bet you may have either an OS issue (which affect all processes
randomly) either an hardware issue (corrupting RAM segments?)
If you want to discover where you tomcat is eating all it's CPU cycle, i
recommend you issue a 'kill -3 java process id', this will dump in
java stdout a list of current stacktrace, including native frames. You
might get there hints on what is problematic (might simply be an
HttpThread in a webapp endless loop)

Our main application uses Hibernate to persist objects and C3P0 to control
the connection pool. Here's the configuration file:
hibernate.connection.driver_class com.p6spy.engine.spy.P6SpyDriver
hibernate.connection.url jdbc:oracle:thin:@dbhost:1521:sid
hibernate.connection.username user
hibernate.connection.password pass
hibernate.transaction.factory_class =
org.hibernate.transaction.JDBCTransactionFactory
hibernate.use_outer_join true
hibernate.show_sql false
hibernate.c3p0.minPoolSize = 10
hibernate.c3p0.maxPoolSize = 200;
hibernate.c3p0.min_size=10
hibernate.c3p0.max_size=200
hibernate.c3p0.timeout=5000
hibernate.c3p0.max_statements=0
hibernate.cglib.use_reflection_optimizer=true
hibernate.dialect org.hibernate.dialect.OracleDialect
I use the P6SpyDriver to be able to log the SQL queries that go through to
the Oracle database, but I have the same problem with the OracleDriver as
well. So here's the problem:
After some time running one java process begins using 100% CPU; strace shows
this:
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0x55d32bda)= -442421359
futex(0x805c770, FUTEX_WAIT, 2, NULL) = -1 EAGAIN (Resource temporarily
unavailable)
futex(0x81ff918, FUTEX_REQUEUE, 1, 2147483647, 0x805c770) = 1
futex(0x805c770, FUTEX_WAKE, 1) = 1
futex(0x805c7f0, FUTEX_WAIT, 2, NULL) = 0
futex(0x805c7f0, FUTEX_WAKE, 1) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
rt_sigreturn(0x500ddbda)= -442421359
futex(0x805c770, FUTEX_WAIT, 2, NULL) = 0
futex(0x81ff918, FUTEX_REQUEUE, 1, 2147483647, 0x805c770) = 1
futex(0x805c770, FUTEX_WAKE, 1) = 1
futex(0x805c7f0, FUTEX_WAIT, 2, NULL) = 0
futex(0x805c7f0, FUTEX_WAKE, 1) = 0
This may stay like that for the whole day, tomcat being responsive, or other
processes may end up using 100% CPU as well and presenting the same behavior
while on strace. Eventually, tomcat may become unresponsive, but I could not
estabilish a pattern. I found similar SIGSEGV/futex behavior on a
non-100%-using process, too:

Re: Post request to 'j_security_check' after tomcat restart or se ssio n timeout produces error 400
Hi, First, you must understand in form based login, access to the form should never be done directly, that's because the container can accept a form login only if before the user tried to access an area requiring authentification. In simple terms, you see the form because the container has decided it required your credentials, not because you just wanted to log in. Now in your case, after a session expire, when the user submit the form, tomcat just notice it gets an access to j_security_check while user session (which has been reset) show no track of a previous attempt to access a secure area needing authentification. The container then concludes naturally it is an attempt at accessing directly the j_security_check and just ignore the call, sending a 400. At this step, tomcat has not saved the user/pass. In your error handler you redirect to secure area. Then naturally, tomcat now trigger the code requesting credential and show again the login form. So there is no solution to solve your problem, except perhaps increasing session timeout to limit the number of 'show form - timeout - submit form' The case of tomcat shutting down my be due to error are persisting the sessions (See output at tomcat shutdown/startup and check for session persistence errors) regards, David Delbecq Amol Upadhye a écrit : Anybody know about the problem I have as described in below email?

changes in tomcat realms between 5.5.7 and 5.5.16?
Hello, I have a webapp here which comes with it's own realms. It's working prefectly in tomcat 5.5.7. I deployed this application and copied the realm files (common/lib/MyRealm-api.jar and server/lib/MyRealm-impl-1.0.jar) to a new tomcat installation. I the deployed to webapp and tried to access a secure area. To my surprise, it seems the user trying to access it is identified ok (according to my realm logs, everything is ok), but gets a refusal from tomcat. The exact same user and same .war (which includes a context in META-INF/) has no problems with tomcat 5.5.7 What change in realm / identification management in tomcat could cause this?

restricting webapp reloading on ressources changes
Hello, I have configured my developpment tomcat to automatically check for ressoures changes in the webapp folder, making it easier to update JSPs. The webapp is slow to load because of a few servelt i need along with those jsps. during development, i sometimes need to update the resource bundles for i18n. Those are located in WEB-INF/classes/path/bundle_language.properties As they are in WEB-INF/classes, tomcat things classes have changed and it need to reload the webapp, which take a bunch of time, each time i update an i18n. Is there a way to tell tomcat to not reload webapp on changes to WEB-INF/classes/**.properties ? Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Private variables in custom tags on Tomcat
Stephen Gray a écrit :
Hello all,
I've come across a problem with using private variables in custom tags
with Tomcat. I have this tag class:
public class TestTag extends TagSupport {
private Date testDate = new Date();
public int doStartTag() throws JspException {
pageContext.setAttribute(date, testDate);
return Tag.EVAL_BODY_INCLUDE;
}
}
accessed from a jsp via: t:Test${date}/Test
You doing it wrong, the specs tell you that the tag will not be altered
between begin of doStartTag() and exit doEndTag(), so you can not assume
the state of local variables to stay constant or be reset after
doEndTag() has been called. You don't even have guarantees the same tag
instance won't be used in separate pages :) If you take a look at
generated code from .jsp in catalina you will notice tomcat is doing tag
pooling.
I suggest you read details of doStartTag() and doEndTag() in javadoc:
http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/jsp/tagext/Tag.html#doStartTag()
http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/jsp/tagext/Tag.html#doEndTag()
In short:
The doStartTag method assumes that the properties pageContext and parent
have been set. It also assumes that any properties exposed as attributes
have been set too. When this method is invoked, the body has not yet
been evaluated.
That's all you can assume :)
in you case, i suggest you do
public int doStartTag() throws JspException {
testDate = new Date();
There's also a tld file that defines the Test tag linked to the
TestTag class with one variable (date).
If I open my browser and go to the jsp it displays the current
date/time. If I then open a browser on a different machine and go to
the jsp it displays the same date/time, which means (I think) that
Tomcat is creating one instance of my TestTag class in the application
context and handing out references to it to all users.
The problem with this is that private variables are usually used to
store the value of tag attributes after they are set via setter
methods. If 2 people access the tag at more or less the same time then
there's a chance that one user's attributes will clobber the other's.
no, there is no clash, as a tag won't be shared between doStartTag() and
doEndTag()
Can someone tell me whether I'm doing something wrong here - and if
not perhaps Tomcat should be creating a separate instance of the tag
class for each session?
Tomcat uses pooling for performance reason. A set of instances is reused
when it is safe to do so.
Thanks,
Steve

Re: Rephrased: Maximum number of simultaneous HTTP connections
Tp a écrit : Hi, we have to develop a high performance chat based only on HTML and HTTP only for a television company. The chat's output window requires one open HTTP connection per client, which means that you need at least 3000 simultaneous ie. open HTTP connections for 3000 chatters. To the former post people replied that HTTP in combination with the Servlet API is not made for this. The basic problem is that you a.) run out of connections and b.) out of threads after a while. The servlet API of Tomcat dedicates one Thread to each connection, which is particular bad. If you don't like it, complain to sun about their j2ee specs. In my point of view, this is really good as it guarantee context isolation of requests for application writer. And there seems to be no workaround, because the connection will close after the doGet() and doPost() method finishes (is that actually true?). So, the only way to keep 3000 simultaneous connections is to keep 3000 of those methods from returning, wehich means keeping 3000 threads busy. So I guess my question is: How many TCP connections can be created on a single machine using Java and then how many threads can be created so that application still responds? I assume that the machine runs on a Pentium 4 3.2 Ghz with 1 GB of RAM under linux and that all the file descriptor limits are set to the maximum. I think i already answered you in my previous mail. The answer is... depends! Can anybody give me some Hardware and Software recommendations on a Java Application sever, which can handle up to 3000 simultaneous HTTP connections and still respond? I know for example that BEA and JRun are very performant, but unfortuantely BEA is to expensive and then Macromedia only talks about the HTTP requests per second in their benchmarking tests, which is very different from what I'm asking. yours, Tim - 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]
Re: Rephrased: Maximum number of simultaneous HTTP connections
Here a diagram: Client sends GET - Server Server sends HEADERS (Content Encoding: Chunked) - Client Server sends chunks - Client Client displays them whenever they arrive. Just one point. If your 'client' is a classical browser it won't work like this out of the box, for the simple reason you have no guarantee the client will do any display before it receive /html There are provisition in http standard for a progressive display of a page. I can't remember like that the references in http 1.1 specs, just give it a look. It's based on a server pushing of page refreshes on a keep-alive connection. But it need special headers. I could just remember the HttpRespone Objects and use one thread, which gets, when new messages arrive in the queue. The thread then could println() them to all he HttpRespones. This would save me all the Threads. Hmm, sounds good, or have I missed somthing?! Yes, one thing, when doGet() returns, the container *could* close the connection. (This is tomcat internal dependent and should not be assumed as deterministic). As a side note, as stated by other people already, you should probably write your own standalone application if you intend to keep all connections alive for your chat. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: error in tomcat
Content in webapp should take precedence on content of $CATALINA_HOME/conf/web.xml as stated in servlet specs about implicit mappings. At least that's how i understand the specs. The container is allowed to add it's own servlet and mapping but, except for implicit mappings defined in specs, they should not interfere with the webapp. Vinu Varghese a écrit : default is a valid servlet name, but it is already defined in $CATALINA_HOME/conf/web.xml. So we can't use that name in our web.xmls Just check the introduction section inside that file. :-) - Regards Vinu David Delbecq wrote: Yes, renaming this does solve the problem, but i can't see in servlet specs where it's stated 'default' is not a valid logical name for a servlet.

Re: Fast response, using valves
Perhaps because, in the version without valve, you benchmarking tool use
the expected behaviour of browsers when they have an active cache:
request 'if-modified-since', to which tomcat will respond a 'not modified'.
Rumata a écrit :
Hello.
I'm trying to make Tomcat server response to some kind of request as
fast as possible. As far as I understood I can stop processing of
request using a valve registered in the Engine pipeline.
I wrote the following code:
public class testValve extends org.apache.catalina.valves.ValveBase {
public void invoke(Request request, Response response) throws IOException,
ServletException {
if (request.getRequestURI().equals(/testValve/hello_java)) {
response.getOutputStream().print(htmlbodyHello
All!brRumata/body/html);
response.sendAcknowledgement();
response.finishResponse();
response.flushBuffer();
return;
}
getNext().invoke(request, response);
}
}
and registered this valve in engine section.
I also wrote a sample servlet with the same output.
Now I'm trying to benchmark the whole thing and I get strange results:
valve is slower than the servlet!
Where I am mistaken?
Thanks,
Ilya.

Re: Encoding and Operative System
When there is no clue on what the content encoding of a form is and no default value, most framework end-up using the platform default encoding (for debian system, it seems to be iso-8859-1). The problem is most browser do not send the content encoding along with the form, so the solution is generally to set the default encoding of your framework to UTF-8 (assuming the framework can do it). Another solution is to use a request filter that will do a 'request.setCharacterEncoding(UTF-8);' Morten Andersen a écrit : On my site the users edit pages using a multipart form. There are differences between the way the content is being decoded on the server depending on the OS. (My guess). The uploaded content is stored in XML files and must then later be displayed to the user. I have spent the weekend trying to get this to work on the Debian based production server. How does the OS effect the decoding / accepting of the submitted forms? I have the following servers: Tomcat 5.0.28 Development server: Windows Old server: FreeBSD New server: Debian (Can't accept UTF-8 form submits) - 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]
Re: JNDIRealm why performing two queries against AD
Hi,
I think users of this mailing list are more used to java stacktrace then
ldap low level protocol :)
the JNDIRealm is using the LDAP contextFactory in your case, i suggest
you run tomcat in eclipse with breakpoints inside JNDIRealms, and do a
step by step to locate which call you think is wrong with the realm, bu
i suspect the context is simply getting informations about the user
after the binding to get roles of user.

It works.
But when I take a look with Etherreal, I See the following:
I would expect the communication to finish after frame 6. (After the bind

explain what happen in frame 7 to 10 ?

error in tomcat
Hello, after a restart of tomcat we got this error. This is strange, we didn't have it before. Tomcat is configured with 2 virtual hosts, eahc has his own webapps directory.

Re: How can I set tomcat NOT Case Sensitive
Buddy wu a écrit : 2006/3/7, David Kerber [EMAIL PROTECTED]: Context caseSensitive=false thanks a lot. it worked. and I think someone discussed other problem of these question maybe right. but my goal is only to let tomcat's URL or URI (I don't kown which is wright, or all are write) case-insensitive. I don't care the case-sensitive feature in jsp or servlet file can work( maybe it MUST case-sensitive, because of java language, but I don't care about these.

That's not where security problem lies: Let's assume your public site is at http://yourserver/yourwebapp/index.jsp if casesensitiveness is deactivated and you are using a case sensitive filesystem (like the microsoft ones), accessing http://yourserver/yourwebapp/index.jsP will point to same filesystem ressouce, but with one exception, it will not be handled by jsp engine and requester will simply get the jsp source instead of generated html (a jsp source could contain potentially critical informations like database connection informations) More dangerous, suppose your application have an admin interface located at http://yourserver/yourwebapp/admin/ with a security-constraint in web.xml mapped to 'admin/*', any anonymous user can have his browser point at 'AdMiN/' and will have access to admin interface without authentification, bypassing securities!

Re: [tomcat] : request.setCharacterEncoding (UTF-8) doesn't work ?
sol myr a écrit : Hi, I'm having a problem with HttpServletRequest.setCharacterEncoding(UTF-8). Basically, tomcat seems to ignore it completely, and assume latin1 encoding. request.setCharacterEncoding(UTF-8) must be called prior to any request.getParameter() call. If your code or any filter or any tomcat valve does a call to request.getParameter() or any other method that would trigger the decoding of parameter, the query is decoded with default character encoding (that is the one sent by browser or the one specified by tomcat connector or the platform default encoding, which ever is defined first). Here's the details: - I have an html form where user should type data in *Chinese*. - The browser (IE6) knows that the form data should be sent to the server, encoded as UTF-8 ( this encoding is mentioned in my content-type as well as in from accept-charset=UTF-8 ). That's the correct way. - I can actually see that the browser sends the data correctly (this is a GET, so I can see the encoding)... Does browser send a header with request encoding? - On the servlet size, I write: request.setCharacterEncoding(UTF-8); String p=request.getParameter(name); Unfortunatelly, this simply doesn't work. Tomcat reads the parameters as if they were latin1 ... I can extract them by forcefully converting back to utf-8, but it's ugly and not portable... I know you can configure tomcat's Connector to use utf-8, but I really don't want to do it ( client has a standard Tomcat installation, and I'm absolutely not allowed to touch it). Is there any reason why tomcat would ignore my request.setCharacterEncoding ? Am I doing something wrong, or is Tomcat just ignoring the j2ee spec in this point ?

Re: How can I set tomcat NOT Case Sensitive
Looking at code, it seems the casesensitive flag is used when a ressources is loaded from filesystem (amongst others). if casesensitive is true, the absolute filename of loaded ressource is compared to the requested ressource (in filedircontext). If casesensitive is removed, anything accepted by new file() is returned as is. I don't know if the casesensistive flag is used by anything else then file loading.

Re: How can I set tomcat NOT Case Sensitive
The compiler does exactly what his job is, compiling *.jsp, not *.Jsp not *.jSp or alike, following the specs. The casesensitive flag is there only to deactivate tomcat internal checks on case sensitive filesystems (where this check is just taking cpu time with no need). David Kerber a écrit : Ok, I see that, and it's kind of scary! That seems like a pretty poor design for the compiler not to handle that kind of change. Thanks for explaining... Dave Tim Lucia wrote: If you ask for /path/to/some.JSP, you will see the source code of the jsp, since the jsp compiler is mapped to *.jsp (and not *.JSP).

Re: Can not look at the Tomcat server from another stations.
Hi, Check in server.xml if you have configured a RemoteAddrValve. This is this valve which could refuse remote connection based on ip.

Re: Problems Starting Tomcat

The most visible thing that has changed is that my home directory now has a different path. Before the move, my installation of Tomcat worked fine. Now it won't start (not quite true, see below). I have searched for references to the old home directory path (only in files such as conf/Catalina/localhost/my-web-app.xml) and modified them accordingly, but this doesn't fix the problem. I have modified my JAVA_HOME and CATALINA_HOME environment variables to point to the correct directories. They are correctly reported when I run startup.sh and shutdown.sh.

Re: Multiple webapps using one war file
While it is possible to put some of the librarie out of .war, inside common, you must be aware of side effects. Libraries like struts are not designed to run multiple context within a given classloader (The servelt, for example, can only be instanciated once). I don't know for Hibernate and for etc :) Also, you could take a look at .ear if you need to play with a common part and multiple .war. But tomcat does not deploy .ear, you must use a full featured J2EE container for this. Mikolaj Rydzewski a écrit : Hello, I've got rather complex web application (struts, hibernate, etc) which runs on Tomcat. There is a need to deploy this webapp for various customers.

Re: JAAS : HTTP 400 Invalid direct reference to form login ... (JAAS + Filter + j_security_check)

Re: JAAS : HTTP 400 Invalid direct reference to form login ... (JAAS + Filter + j_security_check)
The most basic way i see is to have a class with 3 static methods and one static field:: setMessage(), getMessage(), clearMessage() private static ThreadLocal message = new ThreadLocal; ... message.set(theMessage); ... return (String)message.get(); your jaas would do a setMessage() and your error.jsp wouold do a getMessage() be carefull, this class must be visible to both you jaas and your webapp Vincent Delhommois a écrit : Thanks for the answer. You are right, I will check this solution with the ThreadLocal pattern (i don't know at all).

Re: Changing content of response on canceled basic authentication
put your response.setHeader(WWW-Authenticate,Basic realm=\MySystem\); insode your error page instead of authentification servlet. (I guess sendError() clear all headers) Oliver Schoenwald a écrit : Hello fellow tomcat users, I'm running Tomcat 5.5.4 with Apache 2.0.54 and mod_jk. The system uses basic authentication to serve certain pages for authenticated users. One of my users said that if he enters my system and is being asked to authenticate via that popup-windows, he sometimes hits the cancel-button of that popup-window. After that he his shown a page that seems to be generated from tomcat: HTTP Status 401 - unauthorized *type* Status report *message* _unauthorized_ *description* _This request requires HTTP authentication (unauthorized)._ Apache Tomcat/5.5.7 The users said (and I concur) that this page is not only too technical, but it doesn't contain any informations for users that have forgotten their passwords or have to apply for their own account. Recently I tried out to set the error-page in web.xml for response-code 401 to show a certain page with infos about forgotten passwords and how to apply for a new account, but after I restarted the server noone was able to login any longer. Whenever someone tried to open one page that required authentication, the defined error-page for error 401 was shown and no authentication request was passed to the client. Here some internas about my application: My web application is handling authentication internally, meaning I don't use an authentication realm in web.xml. A central Controller-Servlet (the one and only servlet of the whole web application, viva MVC) decides when a certain request requires authentication. When the requires credentials are not already part of the request, the Controller-Servlet sends the following as response using the Servlet-API: response.setHeader(WWW-Authenticate,Basic realm=\MySystem\); response.sendError(401,unauthorized); Note: response is the HttpServletResponse-Object. When no error-page for error 401 is defined in web.xml that works properly. Here my questions: Can I configure tomcat properly without changing its code to send another authentication required-page instead of the defaut error-content?

Re: Use the tomcat authentification mecanisms in a webapp
Hello Poornachandran, as i said webapp X manage authentification all by itself (basically using it's own providers, so there is now security constraint and so on in the web.xml, webapp does not use container managed security, and i have no control over this, closed source webapp), but it provides an extension mecanism (implement a given interface). I'd like to implement a simple class that just do something like tomcatContainer.checkCredentials(user,userprovidedpass), which will check those credentials against configured realm. Or, if i have no other choice, will instanciate the realm, configure it and use it. (I just hope don't need to do that, this sound awfull). So, obviously, in webapp, a request.getUserPrincipal() will always return null. Poornachandran a écrit : Hi David, I am just wondering after your app authenticates, are you able to get not-null from request.getUserPrincipal().

Re: time/date stamp differences
You mean the .jsps do not get recompiled after redeploy? What procedure do you follow to rollback? Do you do a 'undeploy/redeploy process'? I think doing a undeploy should remove the associated work directory, where tomcat store all generated jsp source / jsp .class Hall, Scott a écrit : Hello Tomcat Users, We have currently begun the migration from 5.5.7 to 5.5.15 in my shop. All has been going smoothly except for one quirk that we don't seem to understand. I apologize if this has been covered in some form, but I've spent a good portion of the past two days looking for an answer and haven't see any mention. The problem is that the way times/dates of exploded WAR files are handled between 5.5.7 and 5.5.15. If I take two similarly configured Tomcat installations, one 5.5.7 and one 5.5.15 and deploy identical WAR files to it, I get two diffent results. In the 5.5.7 installation all the files exploded from the WAR in the webapps directory have the time/date stamp of when it was exploded. In the 5.5.15 installation, all the files exploded in the webapps directory have the original time date stamps contained inside the WAR. In a perfect world this wouldn't be much of a problem, but it does present an issue in our shop where it is not uncommon to have to 'roll-back' to a previous version of a WAR. Under 5.5.7 this is not a problem since the redeployed old file has a newer time/date stamp, but under 5.5.15 it's a little trickier since it won't recompile files with older time stamps. This probably wouldn't be a problem if Tomcat would recompile files with ANY timestamp change to them as opposed to the method in which it currently works. Has anyone else noticed this issue?

Marc Wentink a écrit : Ok, it seems to work putting the class in C:\Program Files\Apache Group\Tomcat 4.1\shared The servlet now starts up. \shared is, after reading the docs the general place for classes used by all apps. I won't recommand putting classes in /share unless really needed (shared libs poses problems when different web applications requires different version of a shared library and according to tomcat4 classloader how-to the instance are already shared, so you can get side effects from one webapp to the other). If you servlet works when the class is in /shared then it should work exactly the same if class is in WEB-INF/lib of your webapp It got me further, sorry to bother you guys so much, this it the idea of my managers: I should turn a java program into a servlet and run it in Tomcat. The idea is this repeatedly called java program would work more efficiently as a servlet in Tomcat. The java program stops and starts the Virtual Machine all the time, a servlet in Tomcat should not. The Java program is written with JDK 1.42 hence I believe I should use Tomcat 4.1 Tomcat 5.5 works also on jdk 1.4 (just add the compatibility package as stated in doc) Keep in mind j2ee application have strongly different design then J2se applications! Has big priority since the performance of our Intranet site is so low it going to all kinds of political high ohmens here. So I am under pressure to do this fast, and try to read the docs real quickly, but I do not always succeed. So my apoligies. But any help appreciated. Mmm your intraner is instanciating java application which return html results? Clearly the job of a servlet ;) But if you comme from j2se environment, you might need to grab a few courses on web-tiers, jsp and so on before messing around! - 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]

Re: How to install a simple servlet in Tomcat?
You must put the class in a .jar itself located in the WEB-INF/lib
folder of a .war or you must put the class in WEB-INF/classes of a .war
You must also setup your servlet un WEB-INF/web.xml
Then you must deploy you .war in tomcat (the easiest way is to use the
manager: http://tomcat.apache.org/tomcat-5.5-doc/manager-howto.html)
If you don't know what web.xml and what a .war are, i suggest you take a
look at http://java.sun.com/j2ee/tutorial/1_3-fcs/index.html section
about web technology.

Re: Tomcat and client certificates
Hi Yes, it is possible. From connector configuration doc: clientAuth: Set this value to true if you want Tomcat to require all SSL clients to present a client Certificate in order to use this socket. Set this value to want if you want Tomcat to request a client Certificate, but not fail if one isn't presented. So in your configuration, change clientAuth=false to clientAuth=want and connector will accept connection be there a certificate or not. But don't forget login-config auth-methodCLIENT-CERT/auth-method /login-config means access to /html/* will be refused to users not presenting a certificate. (They can still access other webapps in tomcat if those have a login-config not based on certificate and they can also browse in ssl the non restricted area of client-cert based webapp) for sensitive areas, you might also be interrested in adding, in particular for basic authentification based webapps ... user-data-constraint transport-guaranteeCONFIDENTIAL/transport-guarantee /user-data-constraint /security-constraint Le Mercredi 01 Février 2006 17:55, Markus a écrit : Creating client certs is no problem, I already had client authentication working on the Connector-Level.

java.io.* class imported by tomcat.
All IOException which may occur during processing are managed with their full
package:

My site runs all https, and when I registered my ssl certificate, it is under the http://www.xxx.com. And when the user hits the site without the 'www' it brings up a invalid certificate. It shows the lock, but it says it is not certified by verisign. Any ideas why this is occuring, and any ideas to redirect the bad url to the good one? Adult sites run on tomcat now? :p It is possible the search bots were misled by some header found in your response.

Go to http://www.xxx.com/admin/, fill in username/password of admin and modify the default host to respond only to alias www.xxx.com Of course, requests in the form http(s)://xxx.com will not be responded anymore.

Re: Deploying Servlet Project from Windows to Fedora
Hi, The main difference between windows and linux for you is at the filesystem level i think. Check twice the configuration of your servlets in web.xml and the files in your war for uppercase/lower case mistakes. I may be you renamed at some point myServlet.java to MyServlet.java but never cleared the .class so you end up with a myServlet.class in your war, which is extracted by tomcat (tomcat always extract .war, it does not access it directly) as myServlet.class and when it later tries to load the class MyServlet using file MyServlet.class, it's not a problem in windows (myServlet.class is opened and contains the MyServlet class) but it is on linux (Myservlet.class is not the same as myServlet.class). The uppercase/lowercase problem might also be in having a directory named WEB-INF/CLASSES or web-inf/classes instead of WEB-INF/classes This is just a suggestion, but it may be the most obvious problem. Also, the error messages from tomcat might be usefull to find the problem :p regards Le Jeudi 1 Décembre 2005 15:47, Aydın Toprak a écrit : Hii, I have developed web based project that covers many servlets and uses Postgresql dataBase, on ;Windows platform...

Re: How to share resources across two applications
Hi, maybe the problem is not were we thought it was. If you get a NullPointerException a (1) (i mean not somewhere deeper inside 1 but exactly at 1), that can only mean getServletContext() returned false. This may be the case if servelt was not properly initialized. Check your init(ServletConfig config) method of your servlet and check twice it calls it's ancestor's method (super.init(config)) because it's the ancestor which will set the servlet context.

Re: Tomcat User Permession
Question is not clear, but i'll try to reply. All action attempted by any code inside the jvm running tomcat (that is operations done by JSP, servlet, realms, tomcat itself and any other java classes you may add to webapp) are done on behalf of the user which started tomcat. So if you start tomcat by hand like this: [EMAIL PROTECTED]:~/tomcat/jakarta-tomcat-5.5.7$ bin/startup.sh All action will be done on behalf of user 'delbd' If you start tomcat in a startup script, change recommend you set the user to a user named, for example, 'tomcat' which has write access limited to the tomcat directory. Keep in mind, if you want your tomcat to listen on port 80 (this port is reserved for root in linux as it is a so called low port), you will then need to run tomcat as root, which is clearly NOT recommanded! (prefer to run an apache http server on port 80 and prowy the tomcat server using mod_jk) Last but not least, If your tomcat webapp is to serve only html files, it more performant to stick with apache http server!

Re: classloader during tomcat startup
Well, i saw the ServletContextListener thingies.
Here is what i read about it, not quite the same, in servlet 2.4
specifications:
SRV.10.3.2Deployment Declarations
Listener classes are declared in the Web application deployment
descriptor using the
listener element. They are listed by class name in the order in which
they are to be
invoked.
SRV.10.3.3Listener Registration
The Web container creates an instance of each listener class and
registers it for event
notifications prior to the processing of the first request by the
application. The Web
container registers the listener instances according to the interfaces
they implement
and the order in which they appear in the deployment descriptor. During Web
application execution, listeners are invoked in the order of their
registration.
It is also stated there:
SRV.14.2.12ServletContextListener
public interface ServletContextListener extends
java.util.EventListener
All Superinterfaces: java.util.EventListener
Implementations of this interface receive notifications about changes
to the serv-
let context of the web application they are part of. To receive
notification events,
the implementation class must be configured in the deployment
descriptor for the
web application.
Since: v 2.3
See Also: ServletContextEvent
So, i agree you can create a ServletContextListener, but you must anyway
declare them in the web.xml. The container is not supposed to scan the .jar
and WEB-INF/classes for them, mainly because to know if a Class implement an
interface, you need to get the Class objet and so you run the static
code of the class.
Last but not least, using a Servlet has the additional advantage it can
be easily configured
if needed without ressorting to an additionnal config file in the classpath.
Robert Graf-Waczenski a écrit :
Using the load-on-startup mechanism was the way to go with older
servlet APIs. Nowadays, with servlet API 2.4, having a class
implement the ServletContextListener interface is better in my eyes.
Here you go:
public class MyInitClass implements ServletContextListener
{
static {
// do your static stuff during class loading
}
public void contextInitialized(ServletContextEvent event)
{
// do your init stuff
}
public void contextDestroyed(ServletContextEvent event)
{
// do your destroy stuff
// e.g. cleanup static buffers etc.
}
}
Tomcat automatically finds implementors of the ServletContextListener
interface and calls their interface methods to notify them of
their own context startup and their own context shutdown.
So if you have several contexts and for each of them several such
listener classes, tomcat calls the listener methods of the
correct (i.e. those belonging to the context) classes when the
context is started or shut down.
Your web.xml can remain unchanged for this.

Subject: Re: classloader during tomcat startup
Creating an initialisation servlet for your webapp would be a
good way.
Create a servlet and map it in web.xml adding a
load-on-startup element
with a non zero value. In the servlet init you can then setup all
classes you need.
For classloading hierarchy in tomcat, take a look at
http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html

Tomcat loads all .jar descriptor at webapp startup so it
know which .jar
contains
which class. But it does not load the .class binary content;
Each time a class is required, a Class is request to
classloader by jvm.
If this is first time classloader has to return the Class,
it initialize
it.
So static block is run at first time class is requested.
This is common sense as it prevents initialising classes
you never use
in your library.

Hi all,
I have couple of questions regarding tomcat startup

and create a object of all the classes?
2) if there is a static block in one of the classes , when will it
execute..during startup or when first call is made

I don't see what you are trying to say here. What additional config file in the classpath are you talking about? (I'm not trying to offend you, i'm only asking for clarification.) Just pointing out if he needs some configuration parameters for his static block, he can use the param sections of the servlet config. If you use the listener class and need some configuration, you need to somehow read it from a file as there is not equivalent section. My main problem with the servlet approach is that a servlet has a doGet() method and is therefore supposed to serve web requests, which is not needed in an init class. (Agreed, this is not a major problem, but i like to keep things as small and simple as possible, and a class that *can* serve web requests should also actually be used for this purpose.) Agree on that point, though i most of the time simply don't care :) Robert Robert Graf-Waczenski a écrit : Using the load-on-startup mechanism was the way to go with older servlet APIs.

Re: Global Sessions
It would be a nightmare ;)
Sessions are used to store objects, lots of libs does store in session
various datas.
All objects loaded are linked to their Classloader. So if you store a
org.mycompany.MyData
object under key SOME_KEY in session within webapp1 and you do this in
webapp2:
if (session.getAttribute(SOME_KEY) instanceof org.mycompany.MyData){
// We will never get in this block because
// object was created in webapp1 and we are conparing
// object class to the class MyData loaded from webapp2
// unless MyData is in common/lib
}
If you just want to prevent user from loggin in again, use the single
sign-on valve.

Hi,
Is it possible to have a single session which can be used over
multiple applications on a single server, the basic problem is there
is multiple webapps running on the same server but when a user logs
into one, it would be nice to share all their session data so that
they could switch between applications to avoid
them having to log in again.
I have been looking at the documentation and stuff but so far have
come up blank, was hoping might be able to steer me in the right
direction.
Thanks in advance,

Re: Debugging Tomcat hangs
One stupid suggestion is to run the tomcat inside an environment like eclipse with an eclipse plugin like sysdeo. Then stress the webapplication. When, it 'hangs' issue a 'pause' inside the tomcat jvm, and explore the various threads. Search for 2 kinds of locks: - non returning http-thread leading in emptying the http response thread pool, this thread is use to process the request, so if i put while(1) Thread.sleep(20); inside a servlet i can easily run out of Threads. - non returning connections to connection pool. This one is more tricky, i'll notice lots of threads in object.wait() having a stack comming from commons dbcp. you can try to activate automatic returning of inactive (more than 5 minutes?) connection to the connection pool in tomcat configuration, but this doens really solve problem, it just help prevent final deadlock. David Boyer a écrit : We're running Tomcat 5.0.28 with JDK 1.4.2_8 hosting a single commercial web application on our web server which uses MySQL 4.0.26 running on another server. Both servers are Windows 2003 Enterprise, 2x3.0GHz XEON, 4GB RAM. Our Tomcat instance is dedicated to the commercial web app, and the MySQL instance is hosting only that app's database. The web application is hanging every few days, and neither we nor the vendor can figure out why. Restarting Tomcat is the only way to fix it. We've tried all of the current stable versions of both MySQL and Tomcat, as well as JDK 5 (with Tomcat 5.5.x). The problem happens under each of them. I'm highly confident the problem is with the commercial web app; we have other web applications running under other Tomcat instances on the same server going against a variety of MySQL and MSSQL databases on our database server, and none of them have any problems. If I generate a dump of the JVM using Ctrl-Break while running Tomcat as a console app, what's the best resource for interpreting this? I suspect the problem is a thread deadlock, or something similar. Any other suggestions are appreciated. Thanks!
