Re: dynamical class loading
Hi, I used dynamic class reloading on a commercial J2EE server and, believe me, it brings far more problems than it solves. First, when you dynamically reload a class here is what can happen: webapp start under classloader instance x webapp instanciate class A and store in session session.setAttribute(someKey,someA) class A has changed on disk, classloader reload it using a special class loader and marking this class to be handled by this new classloader (y) now this code A someA = (A)session.getAttribute(someKey) will through a ClassCastException because A.getClass() != session.getAttribute(someKey).getClass() while A.getClass().getName().equals(session.getAttribute(someKey).getClass().getName()) is true :) All code involving static method/static variables is subject to such breakdown. More funny, you can end up in some condition instanciating old version of classes. Thrust me, when dynamically classloading, half of code breaks like this most of time, sometimes silently, and you end up crazy, trying to debug a code which in fact is not bugged. If your webapp is particulary slow to start and you need faster development, better take a look at unit testing of deactivate parts of your webapp when debugging! dumbQuestionsAsker _ a écrit : > can somone give me an information? > I want to know if it is possible to past and load classes into > web-inf/classes path without beeing forced to reload the whole webapp ? > > _ > 10 Mo pour vos pièces jointes avec MSN Hotmail ! > http://www.imagine-msn.com/hotmail/default.aspx?locale=fr-FR > > > - > 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: Problems with graphics on Tomcat 5.5.9 OK!!! BUT.....
Hello, if, like i suppose from your various errors, jfreechart require awt/swing api and do draw on it, you need to run the tomcat server inside a X server, not only do you need to have fonts installed and corresponding X libraries (like your link suggest was problem), you also need to to have X server running and DISPLAY envirronement variable set accordingly. I would first suggest you start tomcat with CATALINA_OPT="-Djava.awt.headless=true" If, like i suppose will be the case, you get HeadlessExceptions when running like this, this mean you definitly need to run tomcat server inside a X environment. regards David Delbecq Mauricio Fernandez A. a écrit : >Thanks for your help > >Now I have reinstalled the XFree86 completly including the Xvfb and I can >start it (XVfb), to test if it is running I execute a xclock and I don´t get >any error, so I think it is running ok > >However, now, when I try to get the jsp wich must show a graphic I get >another different error: > > >java.lang.NoClassDefFoundError > org.jfree.chart.ChartFactory.createBarChart3D(ChartFactory.java:764) > > com.Prueba.comandos.Graficador2.crearBarChart3DVertical(Graficador2.java:19 >6) > > org.apache.jsp.jsp.grafica_jsp._jspService(org.apache.jsp.jsp.grafica_jsp:1 >67) > org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) > javax.servlet.http.HttpServlet.service(HttpServlet.java:802) > > > >And in another web app in the same server the error is: > > >java.lang.NoClassDefFoundError > java.lang.Class.forName0(Native Method) > java.lang.Class.forName(Class.java:164) > java.awt.Toolkit$2.run(Toolkit.java:821) > java.security.AccessController.doPrivileged(Native Method) > java.awt.Toolkit.getDefaultToolkit(Toolkit.java:804) > com.actelion.control.Graficador.asignarBackground(Graficador.java:97) > > com.actelion.control.Graficador.crearBarChartVertical(Graficador.java:524) > > org.apache.jsp.jsp.graficaVisitasMedicasEspecialidadCategoria_jsp._jspServi >ce(org.apache.jsp.jsp.graficaVisitasMedicasEspecialidadCategoria_jsp:198) > org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) > javax.servlet.http.HttpServlet.service(HttpServlet.java:802) > > > >So having in mind that before Xvfb Installation the error was: > >http://www.jfree.org/phpBB2/viewtopic.php?t=14319 > >I think I am just with another different problem. > >Can somebody understand this? > >Thanks > >Mauricio Fernandez > > > > > >>> >>> >>> > >Hi Mauricio, > >I had the same problem.

Re: Non-servlet class cannot access jar file in ./WEB-INF/lib when a Servlet does
Hi, all classes of a webapp which do not come from tomcat server itself do share a common classloader which is an aggregation of the various classes in all WEB-INF/lib/*.jar and in WEB-INF/classes/**/*.class If you get a NoClassDefFoundException, that probably mean you asked some class in server classloader to load some other class (probably by reflection) which is located in WEB-INF/lib. That simply impossible to do because classloaders use a child to parent classloading delegation model, not a parent (server) to child (webapp).

Re: FAQ? shutdown.bat not killing java process on Windows
That's quite a problem ;) Actually your threads should be coded in such a way you may a send a notification in java telling him to finish his job. eg: myNonDaemonThreadICreatedMySelf.stopWorking(); which would set some flag in Thread and then code in your Thread reading the flag knows it has to stop in a clean way. In the past there was a way in java to 'kill' a Thread but this has been deprecated in the Thread api. Tomcat sends a ThreadDeathError to the thread if it tries to interact with its classloader after shutdown, unfortunately, this is not always enough has some Threads do a catch(Error) and then continue their job. The best thing you can do when you have the list of threads still alive after shutdown is to locate the irresponsible threads and fix their code :D Larry Meadors a écrit : >So, once you know the threads that are left, what is the cleanest way >to kill them? > >I have had this problem too, but since it was on a *nix platform, and >just used 'kill' to get rid of the parent process. > >Larry > > >On 10/3/05, Jon Wingfield <[EMAIL PROTECTED]> wrote: > > >>Yep.

Re: Cannot load JDBC driver class 'org.gjt.mm.mysql.Driver'
Just my 2 cents:
Have you tried putting it under shared/lib?
Also, are you sure it's a .jar and not a .zip extension for you file?
Am using here an oracle connector in various webapp. The driver is
under common/lib of tomcat 5.5.7 and i have no problems, so i bet this
is the right location Perhaps your file is corrupted (check you can unzip it and
the driver file exist in it).

Re: Redeploy a war host without reboot
Hello The easiest way is to have each virtual host with it's own webapp directory (like webapps/ for default host, webapps-univaperta for the univaperta host). In each virtualhost, copy the manager webapp (this can be downloaded from tomcat webpage). You should have something like webapps-univaperta/manager/ in your directory structure afterwards. Start tomcat and point your browser to http://www.univaperta.it/manager/html login using the manager account (see manager doc for details at http://www.univaperta.it/manager/). Inside this manager there is everything you need undeploy/deploy/start/stop webapps.

use php in servlet engine.
Hello, We are facing a question here. How to integrate an old existing php site inside a tomcat container. I think about 2 possible solutions: 1) run apache+php on a specific port and have tomcat do some proxying on a url. (like http://server/php/* -> apache-php) 2) create a webapplication supporting php using instruction provided on wiki: http://wiki.apache.org/jakarta-tomcat/UsingPhp The second one is more interesting (no need to run an additionnal apache process) However, am a bit worried about this comment on php documentation: http://be.php.net/manual/en/print/ref.java.php "PHP has a habit of changing the working directory. sapi/servlet will eventually change it back, but while PHP is running the servlet engine may not be able to load any classes from the CLASSPATH which are specified using a relative directory syntax, or find the work directory used for administration and JSP compilation tasks." Has anyone here already tried this and experiences issue with this servlet? Thanks for sharing your experience. -- David Delbecq Royal Meteorological Institute of Belgium - Is there life after /sbin/halt -p? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

No, but code of JNDIRealm can be easily reused to create your own realm.

JNDI Realm with HP-UX passwords (DES crypt use to generate passwords)
Hi, i tried for 2 days to get this running but i always get errors. I did map a NIS (yellow page) password file to a JNDI Realm. This part wen quite well as far as i could tell. To authenticate users i need the realm to check against the encrypted password which are, according to HP-UX doc, encrypted with a DES algorithm. So i provided DES as messagedigest. And guess what? There is no such messageDigest. any idea what i should use? -- David Delbecq Royal Meteorological Institute of Belgium - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
