Re: mod_webapp (Tomcat 4.0 b2, b3): compilation quick fix
It's a bit stupid to reply to your own post. Anyway...
Apache will fail to start with staticly linked mod_webapp due to the
fact that this module is not capable of handling the second pass of the
configuration file successfuly. It will report 'Duplicate connection
name'. The originating file is wa_connection.c. Since the
WebAppConnection has been defined in the first pass, it won't accept the
same one in the second pass because it checks for duplicate connections.

Security issues with tomcat-apache combo
Here is the situation: I have some webapps that I would like to require password access to. I can do this using the web.xml file if I only use tomcat. The problem: I need to have tomcat be a plugin to apache, but when I run them together apache handles all requests that are not for jsp's or servlets. This causes all non jsp or servlet stuff to be unprotected. Questions: Is there a way to allow tomcat to handle all requests and still be able to use the dynamically generated mod_jk.conf-auto file? Is there another better way to setup coordinate security in tomcat+apache?

Mobile Computers
Hello there. This question has nothing to do with APACHE or TOMCAT per say. but here it goes: I think it was sometime time last year when I saw an article in the Linux Journal about mobile computers. I think there were designed to use the CROUSE chip from Transmeta. There was several pictures of some of these computers (If we can call it that...). They seemed to be about the size of a book (8 inches wide by 12 inches long, I think). The looked like a cross between a PDA and one of those PADs used in the Star Trek shows, but bigger. They showed sceeenshots of the display and it showed full color graphics, etc... I think the article mentioned these products were going to be available by now... Does anyone remember this article and if so when on what issue of the Linux Journal was it in? Also any links to the sites where I can find information about buying one of those computers..

Apache Internal Server Error
Hi all. I'm writing because i have a "ghost" problem :) Sometime (i haven't understood when !!) i receive from Apache (1.3.12) an Internal Server Error when i invoke from IE 5.5 my webapp (a servlet and a seriuous of jsp). In mod_jk.log file i saw this message: [jk_ajp13.c (346)]: Into ajp13_marshal_into_msgb [jk_ajp13.c (480)]: ajp13_marshal_into_msgb - Done [jk_ajp13_worker.c (203)]: connection_tcp_get_message: Error - jk_tcp_socket_recvfull failed [jk_ajp13.c (346)]: Into ajp13_marshal_into_msgb [jk_ajp13.c (480)]: ajp13_marshal_into_msgb - Done If i re-send the request to my webapp all return ok (sometime i need 2-3 refresh).

Tomcat3.2+Redhat 7.0+glibc-2.x.x+jdk1.x == stable??
Hi; I know its kind of an open ended question, but I would like some input (factual or anecdotal) on other peoples success in running various combinations of glibc + jdk + kernel (does kernel mattrer much?). I am currently running the Sun JDK 1.3.0 with glibc-2.1.92 and kernel 2.2.16-22 on a *very* stock RH 7.0. This combination is proving itself to be quite unstable, with the Tomcat http listener and/or servlet engine dying under moderate loads (less than 4,000 hits roughly over 8 hours). The glibc + kernel are stock RH7.0 pieces, and while I am sure I can probably gain some stability by upgrading to newer ones, I would like to know if there is a "optimal" (used loosely) combination that exists. I am inheriting this setup from an Admin that thought that Linux 'sucked' and that we should move to NT. The previous admin didn't know how to use rpm, compile a kernel, or have a clue as to what glibc is. Needless to say, I can probably add some value and squeeze some better performance from our Tomcat app servers. Cheers Chris Price
mod_webapp (Tomcat 4.0 b2, b3): compilation quick fix
I've posted to this list a few days ago a message related to the
compilation problems of mod_webapp. It seems that the versions that come
with b2 and b3 of Tomcat 4.0 are screwed (even after cleaning double new
lines in Makefiles). I didn't have the patience to go through the code
to determine why (a lame way of saying that I don't have a clue what's
in there ;-)
The quick fix in order to get it to *compile* is to revert to b1
release. And just as an FYI, it can also be compiled and statically
linked into Apache. Just whack mod_webapp.c into webapplib directory,
put mod_webapp.o into the OBJS in the Makefile for webapplib. This will
place the object file into libwebapp.a after compilation. Then create a
directory under src/modules (Apache source) for it and copy the library
(libwebapp.a) there. Create Makefile.tmpl, for instance:
--
LIB=libwebapp.a
all: ${LIB}
${LIB}:
${RANLIB} $@
clean:
--
libwebapp.module file, for instance:
--
Name: webapp_module
ConfigStart
LIBS="-Lmodules/webapp -L../modules/webapp
-L../../modules/webapp -lwebapp -ldl $LIBS"
RULE_HIDE=yes
ConfigEnd
--
run configure (activate the module) and it should get into Apache after
you run make.

I can startup tomcat, I can go to the example servlets and .jsp's if I go to port 8080 (the default). I have commented out the connector for the HTTP port on server.xml. I can still start Tomcat. On normal startup, does it say Tomcat Server started, check /logs/tomcat.log for errors? When I check the log, no errors are displayed. So... to this point everything looks fine. When I try to restart apache and have the include file in there to mod_jk.conf, apache won't start, but the log does not generate any errors at all, if just doesn't start. Any ideas?

Tomcat3.2.1 -ClassNotFoundException error when using Third-party libraries
Hi there:
I'm having the following configuration and I'm using mod_jk instead of mod_jserv and
starting Tomcat using startup.sh script provided.
Tomcat 3.2.1+Apache1.3.9+Sun Solaris2.7
I have a servlet (TopicServlet) which is using a thirdparty library(PANJA.jar). When
I'm running the same code but using main() I could be able to get the code work but
when I tried to run it as a servlet I'm getting the following error.
I could reach the servlet (configured server.xml and web.xml) and even put PANJA.jar
in WEB-INF/lib of Tomcat. Also I included it(PANJA.jar) in CLASSPATH while running the
startup.sh srcipt.
I don't know where I'm going wrong. Please help.
PS: PANJA.MtClass.mtInitializer(MtClass.java:163) - I'm calling MtClass's
mtInitializer("Topic"). Topic and TopicList are my classes.
Thanks,

Re: Tomcat Sessions
Hi,
I'll wager that you've cached your session object between requests and
the HttpSessionFacade object
has been 'recycled'.
I got horribly burned by this in some code I wrote - I was caching the
session object in the ServletContext (naughty)
and, if the session object was non-null, I tried to fetch a value from
the session.
The problem was that the vital link between the HttpSessionFacade object
and the 'real' session object had been broken.
The facade object couldn't 'delegate' the getValue() call to the real
session object.
Costin has developed some fixes for this in the 3.3 code line and the
same behavior isn't present in tomcat 4.x.
However, tomcat 3.2 does suffer from this problem.
I put together a hack for 3.2.x to get around this problem - in the
org.apache.tomcat.facade.HttpSessionFacade.java
I replaced the original getSession() method with the following method.
As you can see, all I did was to return the 'real' HttpSession
instead of the session facade. Costin's assistance in achieving this
solution was invaluable.
/** begin code fragment ***/
public HttpSession getSession(boolean
create) {
HttpSession realSession = request.getSession( create );
//
test to see if we're using this 'hack' or original behaviour...
String useSessionFacade = System.getProperty("tomcat.useSessionFacade");
if
( (useSessionFacade == null) ||
(useSessionFacade.compareToIgnoreCase("false")==0) ) {
//
// use default behavior (return 'real' session object)
//
return realSession;
}
else {
/*
* return to original tomcat 3.2.1 behaviour - use a sessionFacade
*/
if( realSession == null ) {
if( sessionFacade!=
null) sessionFacade.recycle();
return null;
}
if(sessionFacade==null)
sessionFacade=new
HttpSessionFacade();
sessionFacade.setRealSession(
realSession );
return sessionFacade;
}
}
/*** end code fragment ***/
Alternative:
For those loathe to build a different version of tomcat 3.2.x,
that the following coding approach helped avoid this problem
at least for my situation, (essentially I got rid of the caching).
Sorry. but it's yet another awful counter example [must rank up there
with those "Shape" examples from the GoF pattern book ;-) ]
This one sticks a CountMe object into the session object.
The call to session.isNew() determines whether the session object is
a brand new session object, or whether I've just picked
up the already existing one.
Note, programmatically this does the same as caching the session object,
it's just a little bit different. It won't do for all cases
but, in order to workaround this problem it worked fine for me ;-)
public void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
out.println("");
out.println("SessionTest");
out.println("");
HttpSession session = request.getSession(true);
if ( session.isNew() ) {
out.println("Created brand new session
for this request");
}
CountMe ctr = (CountMe)session.getAttribute("Counter");
if ( ctr == null ) {
out.println("no counter associated
with session - creating new one");
ctr = new CountMe();
ctr.increment();
session.setAttribute("Counter",ctr);
}
else {
ctr.increment();
session.setAttribute("Counter",ctr);
}
out.println("Current value of (Session)counter =
" + ctr.getCounter());
out.println("");
}

Tomcat on Solaris
Hi All -- I'm trying to install Tomcat on Solaris 8 (sparc) and am running into problems. I'm running Tomcat 3.2.1, with java 1.2.2: java version "1.2.2" Solaris VM (build Solaris_JDK_1.2.2_06, native threads, sunwjit) I have tomcat installed and running happily (more or less) on an identical (or so I thought!) machine. First I tried installing from a newly downloaded .tar.gz and got the following exception: Exception in thread "main" java.lang.ExceptionInInitializerError: java.util.Mi ssingResourceException: Can't find resource for base name org.apache.tomcat.reso urces.LocalStrings, locale en at java.lang.Throwable.fillInStackTrace(Native Method) at java.lang.Throwable.(Throwable.java:94) at java.lang.Exception.(Exception.java:42) at java.lang.RuntimeException.(RuntimeException.java:47) at java.util.MissingResourceException.(MissingResourceException.java:54) at java.util.ResourceBundle.getBundle(Compiled Code) at java.util.ResourceBundle.getBundle(ResourceBundle.java:339) at org.apache.tomcat.util.StringManager.(StringManager.java:115) at org.apache.tomcat.util.StringManager.getManager(StringManager.java:260) at Given that, tried tarring up my working tomcat from the other solaris box and moving it over, and got the same exception. All of my environment settings between the two Solaris machines *should* be identical. In fact, the machine that does work was, two weeks ago, an exact copy of the one that is failing... Has anyone run into something similar before? If so, I'd be thrilled to hear a fix. Thanks, Anne [EMAIL PROTECTED]

RE: simple question for servlet-configuration of tomcat
In Tomcat 3.2.2 (I know that's the version I'm running - I think its the version of the source that I checked) the preference for servlet/webApp is hardwired into the code that generates the automatic config files. It takes no notice of anything in the server.xml file (which I think is at least a little unfriendly) To have the behaviour you requested you'll have to edit those (or actually the files you derived from those when you first set up Tomcat) In the case sited for PWS under Win98 it looks like you would have to modify the file derived from %TOMCAT_HOME%\conf\uriworkermap.properties-auto HTH BTW In my example below it looks like Tomcat is serving my static content. :-( > -Original Message- > From: Brett Knights [mailto:[EMAIL PROTECTED]] > Sent: Friday, April 06, 2001 10:16 AM > To: '[EMAIL PROTECTED]' > Subject: RE: simple question for servlet-configuration of tomcat > > > > What I have to do (in the configuration files) when I want > to start my > > servlets with the URL: > > > > http://localhost/servlet/TestServlet > > > > and not with a WEPAPP-Directory like > > http://localhost/example/servlet/TestServlet > > > > Which settings I have to do in the configuration-files and in which > > directory I have to put my Servlets ? > > > > >You just have to declare a context like this: > > > > reloadable="false" > > > > > > > I don't think this is necessarily correct in all circumstances. > > Try as I might I can't get any of the automatically generated > files to reflect that I want to access my servlets at > /webapp/servletalias > rather than at /webapp/servlet/servletalias > > I did succeed in making this work with tomcat and apache by > editing my tomcat.conf file as follows: > > Alias /webApp "C:/ApacheGroup/Tomcat/webapps/webApp " > > Options Indexes FollowSymLinks > > ApJServMount /webApp /webApp >
Re: Problem with mod_jk build
Hi Brandon, First of all, did you download the *source* distribution for Jakarta? In order to compile your own mod_jk.so, you need the source distribution -- jakarta-tomcat-3.2.1-src.tar.gz. When you have the source untarred, cd into the source directory and then to: src/native/apache1.3/ In there you will find Makefiles for different systems. Rename the correct one for your system from Makefile.system to just Makefile. Then run the command 'make' in that directory. If everything is ok, mod-jk.so will be made for you in that directory. Copy it to your apache/libexec and update your httpd.conf (or include mod_jk.conf into your httpd.conf...) It's pretty easy and it worked for me the first time.

Re: Problem with mod_jk build
Do you have these lines, either in mod_jk.conf or httpd.conf LoadModule jk_module libexec/mod_jk.so AddModule mod_jk.c You shouldn't be able to start Apache without them. You should get unknown directive errors. Make sure those are in there somewhere (I recommend putting them in httpd.conf along with all the other module loads). Also I recommend copying mod_jk.conf-auto to mod_jk.conf, and including that file from httpd.conf.

Re: Which workers am I using?
In order to get Apache to use ajp13, you have to use your own config files. The auto files always use ajp12. You'll need to change workers.properties so that your workers have a type of ajp13. I don't think it matters what your workers are called, though most people have the protocol as part of the worker name. It's possible that your worker could have a name with ajp12 in it, even though its type is ajp13 and it might make deceiving log entries that way. -Scott -- Scott Tatum | [EMAIL PROTECTED] Senior Applications Developer, Special Projects WorldCom | http://www.wcom.com/ Peter Smith wrote: > I can see the ajp12 and 13 worker threads being > instantiated (via log messages in the console) when I > crank up Tomcat, but how do I know if the 13's are > being used at all?

Re: Superclass for JSPs?
I honestly don't know if it's possible to subclass your JSP pages, but I may have a hack workaround. First, know that you can declare a 'jspinit()' method that is just like the 'init()' method in your servlet. Search the following doc for details: http://developer.java.sun.com/developer/onlineTraining/JSPIntro/contents.html Also, you might use the 'include' directive to include a jsp file in all of your other jsp pages. For instance, you may write a 'init_and_utils.jsp' file and use the jsp include directive to attach it to each of your other jsp's. --Peter-- --- "Felix A.

Tomcat Sessions
Hi , We are running tomcat 3.2.1 on WinNT with Apache Server 1.3.12, and here is the problem that we are facing with Session: "HttpSession session = getSession(req)" where req is the HttpServletRequest object. is working fine with ServletRunner (provided by Jsdk2.0) but when we start using it with Tomcat, the session object is of type as follows: HTTP Session = org.apache.tomcat.facade.HttpSessionFacade@8f04cf35 Is there any difference in : Jsdk2.0 HttpSession Object & the above one So whenever we try to access the current session object, it seems that we get NULL object in Tomcat. Please help me out in solving this problem... Thanks in advance, Anil
Servlet auto-reloading under ROOT context (was RE: simple question for servlet-configuration of tomcat)
On a slightly related note: are servlets under the ROOT context automatically reloaded? The docs in server.xml would appear to indicate that reloadable="true" is the default, but there's no entry for the ROOT context in my server.xml file, and it appears to be inconsistent on our server with regard to reloading a servlet which has (definitely) changed in webapps/ROOT/WEB-INF/classes (i.e., Tomcat apparently reloaded the servlet each time the class was changed, then suddenly stopped doing so, with no configuration changes made). Would placing an explicit CONTEXT entry for the ROOT in the server.xml file, i.e., resolve this issue? Has anyone else encountered a similar problem? I can supply more configuration upon request, but at least I'll note that the server configuration is with Apache 1.3.14 and Tomcat 3.2.1 running Redhat Linux 7.0 on an Intel box, JDK 1.2.2. Tomcat, aside from slight changes for mod_jk operation with Apache, is unchanged from the default configuration.

Re: Problems with caching?
Are you using the include file directive to include the files? If you are, then that is the problem. JSP's won't recompile if a file they include is updated, only if the jsp file itself is updated. There are two ways to get around this: 1. Load the jsp file and save it (may have to add a space, remove it, then save or something similar) 2. Use the touch command unix to update the timestamps on all your jsp files. This will cause them all to recompile. (e.g. go to your dir with the jsp's and do a "touch *.jsp") This might be preferable since you are dealing with header includes. Hope this helps. -Scott Melissa Matthews wrote: > > > Does anyone know if there is a problem with regular HTML files being > somehow cached by Tomcat 3.2.1 on Solaris 2.8?

RE: virtual hosting with tomcat and apache
Does anyone have any experience with several virtual hosts, all running tomcat in one virtual machine? This seems to be the best solution for us to keep within our server's limits. We have many sites and that many JVM's would take all our resources. Any help would be greatly appreciated. What does your tomcat-apache.conf look like, what does your server.xml look like, do you use mod_jserv, and do you just include the tomcat-apache.conf in your httpd.conf file? Thanks!

So, I'm setting mine up with the "one JVM for all hosts" config. It's actually pretty simple. Use the directive in your server.xml file: In either your httpd.conf or mod_jk.conf, add your Vhost: (can be name-based or ip-based) ServerName your.vhost.domain ServerAdmin your_admin@domain DocumentRoot "/path/to/your/normal/html" JkMount /servlet/* ajp13 JkMount /*.jsp ajp13 Alias /alias_dir "/path/to/your/docBase" allow from all AllowOverride None deny from all AllowOverride None deny from all This simple config works for me. You can add several Vhosts this way, as long as you don't mind running them in the same JVM. Check out the mod_jk Howto. That's where I got most of this info.

Superclass for JSPs?
Hello all, i just started using Java for server-side WEB development ( I've 4 years of this development in C and Perl ). When I read about JSPs, I found than JSP is compiled into servlet on a first call and than runs like a servlet. The question is : is it possible to have a superclass for my JSPs? I need to make some activity before each JSP is called. I made a superclass for my servlets, so I cat write my servlets inherited from baseServlet and do not worry about pre-request activity. But how can I do it for JSP??? Sincerely, Felix.
Apache+Tomcat+vhosts insights, discussion (long)
I too had the utilization problems associated with Apache and Tomcat 3.2.1. Actually, the problem also manifests itself in Tomcat standalone. After researching the problem and eventually coming up with a solution, I realized a couple of things that I have not seen posted to the list, so I thought I would share them and possibly help some others out. First of all let me explain my setup. Our group does a lot of Intranet applications for different groups and we have recently moved from JRun 3 to using Tomcat 3.2.1 for our servlet container. And I must say, even though the initial setup and administration was tedious, Tomcat is a faster, more stable environment for us. Our development environment is a PC running RH6.2, and our production boxes are usually running some version of Solaris, and in this particular case, Solaris 8. Both setups are using Apache1.3.19+Tomcat 3.2.1 and Java SDK 1.3.0_02. We run separate VM's for each virtual host/application. Our production boxes typically hold several production websites, each with their own virtual host. The name of the production box itself doesn't host a site, just the CNAME's we have registered for that host. For example, the production server may be called pserv, with aliases app1, app2, app3, etc. We don't have (or want) a website called pserv.wcomnet.com (wcomnet.com is our Intranet domain), but we do have the websites app1.wcomnet.com, app2.wcomnet.com, etc. I don't know how representative this is of people using Apache+Tomcat and virtual hosts, but it is a good fit for us, and Tomcat handles it well. The configuration files look something like this: -workers.properties- worker.list=app1-ajp12, app2-ajp12, app3-ajp12 worker.app1-ajp12.port=8000 worker.app1-ajp12.host=localhost worker.app1-ajp12.type=ajp12 worker.app1-ajp12.lbfactor=1 worker.app2-ajp12.port=8001 worker.app2-ajp12.host=localhost worker.app2-ajp12.type=ajp12 worker.app2-ajp12.lbfactor=1 worker.app3-ajp12.port=8001 worker.app3-ajp12.host=localhost worker.app3-ajp12.type=ajp12 worker.app3-ajp12.lbfactor=1 -uriworkermap.properties- /*.jsp=app1-ajp12 /servlet/*=app1-ajp12 /*.jsp=app2-ajp12 /servlet/*=app2-ajp12 /*.jsp=app3-ajp12 /servlet/*=app3-ajp12 -mod_jk.conf- JkWorkersFile /usr/tomcat/conf/workers.properties JkLogFile /usr/apache/logs/mod_jk.log JkLogLevel error NameVirtualHost 1.1.1.1 # ip's changed to protect the innocent ServerName app1.wcomnet.com DocumentRoot /usr/tomcat/vhosts/app1 ErrorLog /usr/tomcat/vhosts/app1/WEB-INF/logs/error_log CustomLog /usr/tomcat/vhosts/app1/WEB-INF/logs/access_log common JkLogFile /usr/tomcat/vhosts/app1/WEB-INF/logs/mod_jk.log JkMount /servlet/* app1-ajp12 JkMount /*.jsp app1-ajp12 AllowOverride None deny from all ServerName app2.wcomnet.com DocumentRoot /usr/tomcat/vhosts/app2 ErrorLog /usr/tomcat/vhosts/app2/WEB-INF/logs/error_log CustomLog /usr/tomcat/vhosts/app2/WEB-INF/logs/access_log common JkLogFile /usr/tomcat/vhosts/app2/WEB-INF/logs/mod_jk.log JkMount /servlet/* app2-ajp12 JkMount /*.jsp app2-ajp12 AllowOverride None deny from all ServerName app3.wcomnet.com DocumentRoot /usr/tomcat/vhosts/app3 ErrorLog /usr/tomcat/vhosts/app3/WEB-INF/logs/error_log CustomLog /usr/tomcat/vhosts/app3/WEB-INF/logs/access_log common JkLogFile /usr/tomcat/vhosts/app3/WEB-INF/logs/mod_jk.log JkMount /servlet/* app3-ajp12 JkMount /*.jsp app3-ajp12 AllowOverride None deny from all -server-app1.xml- # most of this is left out, only the custom bits listed I'll exclude server-app2.xml and server-app3.xml for brevity's sake. They are the same as app1's xml file, but with the different directory names and appropriate ports for the Connectors. I'm not sure if the Host directive is even necessary. In a standalone Tomcat setup it would be, but I think the mod_jk.conf is handles that now. I have them in there just in case. I'm sure some of you are already wondering why I didn't use the webapps directory. There are a couple of reasons for that. We have several different developers, each working on their particular applications. I wanted to have the work directory (the auto-compiled servlets from jsp) for a given application located under the webapp's directory structure. That way developers who are mapping drives via Samba can see/manipulate the generated servlet code along with everything else. I could have done that through the ContextManager directive while keeping it under webapps, but that produces some anomalies: - Tomcat automatically looks in the webapps dir and creates contexts for everything there. I already have my contexts setup th

Problems with caching?
Title: Problems with caching? Does anyone know if there is a problem with regular HTML files being somehow cached by Tomcat 3.2.1 on Solaris 2.8? I have replaced some HTML header pages, but I still see the old ones. I have searched and can not find those files anywhere. If I go directly to an shtml file that includes the HTML header files, it shows the new header, but the JSP pages always show the old headers. I tried renaming the header to another name and then the JSP page showed the new header. I have deleted all of the pages from the work directory. Any suggestions? Thanks in advance. Melissa

Hi :-) from my work, I also can not auto-reload MyServlet with jakarta-tomcat-4.0-b(2/3)(standalone, JDK1.3, winnt40). but with jakarta-tomcat-4.0-b1(standalone, JDK1.3, winnt40), auto-reloading works Well, and please notice that only those MyServlet classes which are in WEB-INF/classes(WEB-INF/lib with jar-style?) can be auto-reloaded.

Servlet Contexts and sessions
Hey all. This is sortof a JSP/Servlet related question, but it falls within the scope of this forum: Can someone give me a compelling reason why sessions cannot be shared across contexts? I realize this is part of the Servlet 2.2 spec, and not strictly speaking a tomcat issue, but perhaps there is a way to work around this limitation in tomcat? I can't think of a good reason for disallowing session sharing between contexts. Ideas? Thanks in advance, -Andy
RE: How to reload library classes?
Are there any performance implications when you set the 'reloadable' to true ?

??? Does Tomcat 4 b3 Support Reloading ???
Hello, By reading the documentation, it seems Tomcat 4 b3 should support servlet reloading but this does not seem to be the case. After a fresh install of Tomcat 4 b3 I modified the SnoopServlet and the change was *not* picked up even though the examples Context has reloadable="true" specified. Has anyone else had this problem? Is there a version of Tomcat that *does successfully reload changed servlets? Thanks.
Using the directive (Feature request?)
Is there any plan to include pattern matching in the directive in the server.xml file? Right now, in order to catch requests to mydomain.com and www.mydomain.com, you have to use two directives. The problem with this is that it loads two instances of all your servlets/jsp's. I'm using DB connection pools and I'd like to avoid loading everything twice -- creating twice as many connections to my DB. Something like: or even being able to list multiple combinations, to avoid pattern matching: would really help. I'm using 3.2.1 and haven't tried any of the betas, yet. Is this available in 3.3 or 4.0? Thanks, --jeff

Re: Dates in Java
I think you need a java.sql.Timestamp type as compared to java.util.Date type To create new timestamp or long time = System.currentTimeMillis(); Timestamp currentTime = new Timestamp( time ); ... This object will hold the date and time. If you want to format the time differently use Calendar and Formatter to achieve this.

Well actually in the context of generating web applications, XSLT and JSP are both competing. IMHO, XSLT has the huge advantage of separating content and format, unlike JSP.

First, posting the same question multiple times will not expedite a faster response to your question. People might just get ticked off and not reply at all. Now, I will pose a couple questions: 1. How are you trying to access your servlets? (/mytest/servlets/aaa, mytest/aaa, etc...) 2. What are your configurations, in your webapps web.xml, for your servlets? 3. What is the exact error message you are receiving? 404? 500? etc...

First, posting the same question multiple times will not expedite a faster response to your question. People might just get ticked off and not reply at all. Now, I will pose a couple questions: 1. How are you trying to access your servlets? (/mytest/servlets/aaa, mytest/aaa, etc...) 2. What are your configurations, in your webapps web.xml, for your servlets? 3. What is the exact error message you are receiving? 404? 500? etc... The more information you can provide the faster a solution can be found. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com
Apache + Tomcat configuration
Hi, everyone: I am trying to setup Apache + Tomcat to run JSP and Servlets on Win. 2000. I am using Apache 1.3.19, and Tomcat 3.2.1. I created my own directory in %TOMCAT_HOME%/webapps/mytest, copied the structure from %TOMCAT_HOME%/webapps/examples such as WEB-INF, META-INF I put my servlets .class files in the ../mytest/WEB-INF/classes/aaa.class. I did some configurations in Tomcat: Server.xml, Tomcat-Apache.conf, Tomcat.conf; and in Apache: httpd.conf Now I can use Apache + Tomcat to run my JSP files, BUT I can ONLY run the system provided sample Servlets files. I CAN'T run my own Servelts files no matter where I put the .class files. Could you give me a help for the configuration as my assignment is almost due ?

RE: OutputStream Already in USE ..!!!!
I don't know why you get a OutputStream already in use, but the reason why it works with IE and not with Netscape may be because you do not set properly the Content-type of your image. Indeed, IE seems to be a little bit cleverer than Netscape because it interprets the real content of a file before displaying it instead of only looking at the Content-type header property. So you have to be more explicit with Netscape. Benoît I am using Tomcat and trying to write a Gif file to client browser window using JSP. I use ACME - GifEncoder to convert the picture to GIF. The Encoder needs OutputStream type object as one of the parameter in its constructor. I am using ServletOutputStream object for this, which i got through response.getOutputStream(). But the tomcat gives Error as "OutputStream already been used." But the GIF image is Displayed properly in IE 5.0. It gives ASCII charactes in Netscape. Why is this so. -- The OutputStream already in use is because the automatically generated code in a jsp class file gets the output stream as a JSPWriter therefore when getOutputStream() is called it thinks there is already an 'external lock' of this resource object and doesn't think it can use it. BTW, please post to the list in plain text. This has been stated over and over and is also listed on the website as one of the mailing list guidelines. More people will be willing to answer your questions if you post in plain text. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com

RE: TomCat installation
Hi David, There's really good documentation with the Tomcat 3.2.1 distribution: howto-tomcat et howto-tomcat-apache. I use these well-written to build my systems based on Tomcat and Apache, and they're work great. Anyway, since Tomcat is a Java program, you just need to copy it into a directory and expand all the file and directory from the tar.gz. Then set the JAVA_HOME environment variable to your java path (for example: /usr/local/jdk1.3), and use the startup.sh/bat script which is in the TOMCAT_HOME/bin directory. Sometimes, on Windows, you need to start once the tomcat_env script before starting tomcat to set all the environment variables...

RE: Tomcat 3.2.1 JDK1.3.0 on Solaris - processor usage.
Please see my 3rd paragraph. The readme was the first place I looked. I am aware of this bug. It is not what caused our processor usage to spiral. Perhaps I should have said "all our contexts/webapps are configured correctly". -Original Message- From: DONNIE HALE [mailto:[EMAIL PROTECTED]] Sent: 06 April 2001 13:58 To: [EMAIL PROTECTED] Subject: Re: Tomcat 3.2.1 JDK1.3.0 on Solaris - processor usage. Check out the 3.2.1 release notes at http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/readme - section 6.11. This has been posted a few times here in the last month. Donnie >>> [EMAIL PROTECTED] 04/06/01 06:31AM >>> Has anyone experienced this? Tomcat 3.2.1 with Sun's JDK1.3.0_02 on Solaris 8 64 bit on a twin processor Sparc box. Under certain circumstances (regularly but not consistently) our webapp causes the processor usage of the java process on one processor to rise quickly to 80% and just sit there or therabouts. Bizarrely, this figure (80%) seemed to vary. Sometimes it would be 80, sometimes 90 and originally with Tomcat 3.2 beta8 it was 100%. Restarting Tomcat (and hence the JVM) always solved it. Our root context is configured correctly, so we knew it wasn't the known processor usage bug. We patched Solaris, the JDK and brought Tomcat to 3.2.1 with no success. Eventually we rolled back the JDK (and hence the JVM) to V1.2.2_07 and this solved it. As an aside can anyone point me towards some documentaion about getting the JVM to use both processors? Please bear in mind I am the Tomcat/Solaris guy NOT the webapp developer! Gary
RE: Scope of Mailing List (was RE: Dates in Java)
> Are we in the tomcat-user forum ??? > I don't see the relationship between a so simple constructor problem > (which Javadoc solve quiet easily ...) and Tomcat ... I agree that this list is not the place for this question(the proper place would be java.sun.com JDC groups) but most of the time it is faster and simpler to just answer the questions and get it off the list. Here's a somewhat basic guideline for good posting: * Evaluate scope of question(if it doesn't correlate directly to tomcat don't post it here). An example would be: -> Using java.sql.Date doesn't really belong in tomcat-user. -> Using DB Connection Pooling with Tomcat does belong here. * First check archives(link can be found tomcat website). * Then post it if you still have a question. (Another good guideline is... Please post in plain text. Not HTML, etc.) --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com
