Subject: Re: Get Virtual Path in INIT() function
Dear Craig,
That means, there is no way to get the virtual
path
of current project. Instead, conf/server.xml or
WEB_INF/web.xml should be read so as to get the
path
configuration.
if project APPLE, define a docBase /APPLE/
I should do some hard coding in web.xml like
web-app
servlet-mapping
servlet-name
programMain
/servlet-name
url-pattern
/program/*
/url-pattern
/servlet-mapping
servlet
servlet-nameIndex/servlet-name
servlet-classprogramMain/servlet-class
init-param
param-namepath/param-name
param-value/APPLE/program//param-value
/init-param
/servlet
/web-app
if I want to change docBase from APPLE to ORANGE,
then
I should also change
param-value/APPLE/program//param-value to
param-value/ORANGE/program//param-value
It is not adaptable when docBase path change.
Thx.

Dear Craig,
Is that the servlet instance will be

init() when it is called at first time ?
That is correct. See the servlet spec for more
details:
http://java.sun.com/products/servlet/download.html
My whole picture is :
request - target class - init()
Almost, but not quite, complete. The way I
think of
it is:
request -- servlet definition -- init() if
needed -- service()
The differences from your picture:
* Which servlet definition is selected is based
on
the various
servlet-mapping elements in your web.xml
file.
See the rules
in the servlet spec for how this is
determined.
* There will be an instance of a servlet
*per-servlet-definition*
(i.e. per servlet element in your web.xml
file),
unless your
servlet implements SingleThreadModel -- in
which
case the container
might create more than one instance. (Tomcat
doesn't do this.)
* The very first time a particular servlet
definition is accessed,
the instance will be created and init() will
be
called. Alternatively,
you can declare a load-on-startup element
inside
the servlet
definition to cause the servlet to be loaded
when
the web application
is first started. This is quite handy when
the
initialization process
is time consuming, because you can make it
happen
before the first
request to the servlet.
* For each request (including the first),
service()
will be called.
* Tomcat supports a non-spec-defined (but very
common) feature called
the invoker, where you can execute a URL
that
includes
/servlet/{classname}. In essence, Tomcat
creates a servlet
definition on the fly the first time this is
encountered, and the
rest of the rules defined above are applied.
Thx.

Virtual Host with DHCP
Hi I tried this message on comp.text.xml, but nobody could answer. I guess I should have start by here. Please, give me some help. I've got an adress via DHCP, that mean that the IP numbers change. My localhost is cib.domain.com, but I'd like to have another xxx.domain.com adress, to get two sites distinguished from one another. How to do that on Tomcat4 with Cocoon2 on Win95.? I've tried to put some stuff inside Tomcat server.xml, but first of all, - I 'm not really sure where to put that in the file (inside or outside the main Host /Host ), and then, - I 'am not sure if I'm putting it the right way, and at last - I'am not sure where to put my files, and how to request them from browser Here is what I've put: Host name=xxx.cib.domain.fr Context path= docBase=/ROOT/xxx1 reloadable=true debug=0 / /Host or I also tried combination of Host name=xxx.cib.domain.fr Context path=/ docBase=webapps/ROOT/vendo crossContext=false debug=0 reloadable=true / /Host Please, if someone know how Tomcat4 works, (I 've already read the Host page on the catalina docs) or where to find docs for really newbies, thanks for any help.

Installation issues with Tomcat 4.0-b6 on W2K
Hi, I tried installing Tomcat 4.0-b6 on my W2K laptop and had a couple of issues: 1. The URL http://localhost:8080 , under Netscape 6.0 does not bring up the Tomcat page indicating successful installation, although the logs don't show anything to have failed. Also, the console shows the services starting up just fine. 2. The same holds true for IE5.5 , except that, on IE5.5, when I try the URL http://127.0.0.1:8080, it brings up the Tomcat page indicating successful installation. I checked the Hosts file under %SYSTEM_ROOT%/System32/Drivers/etc and it does have the right entry mapping localhost to 127.0.0.1, so how come I am not seeing the page come up when typing in localhost instead of 127.0.0.1 and why doesn't it work at all for Netscape 6.0? Btw, the only environment variables I am setting are JAVA_HOME and CATALINA_HOME? Do I need anything else for a successful installation? Please let me know a workaround, if it exists, for this behavior? Any help would be greatly appreciated. Thanks, nandu P.S: Am not yet subscribed to this list. Kindly CC me on your replies.

Running Tomcat as a Windows service
Hello, I installed Tomcat as a Windows (NT) service using jk_nt_service and set the service's startup type as automatic, but when I log off, the service shuts down. Is this a bug (in Tomcat, jk_nt_service, or the JRE) and, if so, do you know if the problem is being addressed?

Tomcat Connection Problem
Hi, I have a serious problem, sometimes my JSPs stop getting rendered while static pages are working fine. I am using Apache 1.3.20 with Tomcat 3.2.2 on Linux Kernel 2.4.2-2 for a production server. When I encountered the problem for the first time I thought that it was the java heap problem so now I am starting Tomcat with JVM parameters 96MB initial heap size and 256MB max size. Things were working fine for a while but it again happened, now I am constantly monitoring my application. My server has 512MB RAM which seems OK for the hosted application. But even with a small load this error happened. My static pages keep getting served properly but JSPs don't get rendered at all and after a restart things get fine again. When I examined the mod_jk.log the following errors appear when the JSPs stopped getting served. Please help me with some solution whereby I don't have to keep monitoring and restarting apache and tomcat whenever such errors occur, I am always restarting apache after a tomcat restart which was mentioned in one of the mailing lists as a possible reason for the problem. Till now I am not even sure if this is a JVM problem or what???

RE: Getting the user environment variable::Need help
1) This isn't a Tomcat question: if you'd done the same in a java application, you'd have found the same thing. There are forums, newsgroups, and mailing lists for Java questions. 2) You're confusing environment variables with properties. Properties are defined either by loading them from a properties file, or by specifying them on java's command line (with -D). 3) There is a method, System.getenv(), to get environment variables, but it's deprecated (the whole concept of environment variables is incredibly OS-specific).

RE: Moving /WEB-INF/lib or adding to it in TC 4.0
Correct, that's why it's not advisable to put it there. $CATALINA_HOME/lib is there just because sometimes you want to have libraries accessible by all your web applications WITHOUT putting them in $JAVA_HOME/jre/lib/ext. Yes, there are lots of things that are not advisable. I'm just saying that having a way to extend the places where I look for jar files for a web- app is no worse than existence of the $CATALINA_HOME/lib. I tend to disagree with you. If you consider the fact that everything under $JAVA_HOME/jre/lib/ext is considered trusted code by the VM when you install a SecurityManager, while code in $CATALINA_HOME/lib is not. $CATALINA_HOME/lib is there for a reason... I'm not suggesting putting stuff in the ext directory. I'm suggesting adding stuff to the classpath for a single web application and treat it as if it were in the WEB-INF/lib directory. Yes, but at this point I don't quite get WHY you have to have a JAR file specifically tied to a single Web Application in a directory != from your WEB-INF/lib... It there a solid explanation on why you need this behavior? We have a set of jar files used by several programs which are not web applications. We have a single web app which uses some of the jar files. It does not make sense for the programs that are not web applications to use jar files in the WEB-INF/lib directory nor does it make sense for the web application to use files outside that directory. So when we build a production release we make sure we have copies of the jar files in the right places. However, in development when I make a change to a source file there is much less pain involved if I don't have to make sure to copy the resulting change to the jar file into all of the places it is needed. It is simply easier to point the applications that need it to the central location. Please don't answer that I should have the build script make extra copies of the jar files (which will cause configuration management issues) and please don't answer that the central location be the WEB-INF/lib directory because most of our developers don't see that directory. I simply want to know if it is possible to extend the library path for a web application. At this point, I'm sure the answer is no. Well, the answer IS of course no... :) If you imply such a configuration mechanism (like specify a classpath for every web-application) there might Thanks. be issues from when you move stuff around (like, from your classpath, to WEB-INF/lib), especially in terms of security and class loading issues. I believe that it can be easily solved by putting down some symlinks in your WEB-INF/lib, so that when you jar up the final release you don't even care what you need to copy over or not... Pier We're using Windows (yes too bad for us) so symlinks are out. I'll probably just add a build target to make copies of the required jar files in the WEB-INF\lib directory. Dave Holscher

Servlet/ Database Conenction Persists Question
I have developed a servlet web application which connects to a database to retrieve information. I noticed that if within my servlet I destroy the connection to the database there is no way to reconnect to the database . In other words I need to keep my connection to the database at all times that tomcat is up. My questions include: Is this correct that there is no way to reconnect to the database? If this is not correct, how does one reconnect, and or reinitialize the servlet? Is keeping the persistent connection to the database a heavy burden on tomcat? In other words, is it o.k. to design an application which never releases its conenction to the database? I don't believe my question pertains specifically to Tomcat, so I was wondering whether or not any of you knew where there are list servers which deal with servlets in general. __ Do You Yahoo!?

IllegalStateException: Can't happen
I know this is a repeat. The archives and FAQ offer explanations, but not much help with eliminating this intermittent error. I'm using Tomcat 3.2.1 on WinXP Pro RC2 with MS IE6. Should I move on to Tomcat 3.2.3 or 4.0? Will that help? As noted previously, stopping and restarting tomcat makes the problem go away for awhile, until I make some change to a servlet.

I noticed that if within my servlet I destroy the connection to the database there is no way to reconnect to the database . Maybe this is a JSP thing (I'm not too familiar with those), and JSPs have some weird JDBC cover methods.

Are you getting an exception from DriverManager.getConnection()? Is keeping the persistent connection to the database a heavy burden on tomcat? Persistent connections aren't a burden on Tomcat, but might be on your database, especially if the modifications aren't committed immediately.

Mailing lists for calling Java from Xalan?
Hi folks! Enke, a developer, kindly responded to my query about how to convert dates with XALAN. I still have a more general question, however: How to manipulate DOM using Java from XSLT/Xalan. I believe I sent out another query about how I could not get any of the examples of calling Java code from Xalan to work. I tried the examples in xalan-j_2_2_D6 distribution as well has the ones from Micheal Kay's book XSLT Reference. (I could call javascript from Xalan, however). Perhaps the reason I received no response is that I used the wrong mailing lists? I could not find a [EMAIL PROTECTED] discussed on xml.apache.org. Did I miss something? Where do I post such a query? I would also be interested in learning how to manipulate DOM from Javascript inside of Xalan/XSLT. I assume I need to check out the rhino documentation on mozilla.org for that.

Yes, but at this point I don't quite get WHY you have to have a JAR file specifically tied to a single Web Application in a directory != from your WEB-INF/lib... It there a solid explanation on why you need this behavior? We have a set of jar files used by several programs which are not web applications. We have a single web app which uses some of the jar files. It does not make sense for the programs that are not web applications to use jar files in the WEB-INF/lib directory nor does it make sense for the web application to use files outside that directory. So when we build a production release we make sure we have copies of the jar files in the right places. However, in development when I make a change to a source file there is much less pain involved if I don't have to make sure to copy the resulting change to the jar file into all of the places it is needed. It is simply easier to point the applications that need it to the central location. Please don't answer that I should have the build script make extra copies of the jar files (which will cause configuration management issues) and please don't answer that the central location be the WEB-INF/lib directory because most of our developers don't see that directory. I simply want to know if it is possible to extend the library path for a web application. At this point, I'm sure the answer is no. Well, the answer IS of course no... :) If you imply such a configuration mechanism (like specify a classpath for every web-application) there might be issues from when you move stuff around (like, from your classpath, to WEB-INF/lib), especially in terms of security and class loading issues. I believe that it can be easily solved by putting down some symlinks in your WEB-INF/lib, so that when you jar up the final release you don't even care what you need to copy over or not... Pier I find that a deploy target in my build.xml file, which assembles the web app in Tomcat's webapps directory (including copying JARs that are needed) solves this kind of pain for me. You're absolutely right that the author of a non-web JAR that you're using shouldn't be responsible for pushing JAR files to wherever they are being used -- it should be the responsibility of the user of that JAR to pull as needed. Ant's copy task is smart enough to skip the copying if the JAR file didn't change, so it's still pretty fast. Now, my webapp development loop goes like this: * Edit * ant compile * Fix compiler errors and loop back * ant deploy * Restart the webapp in Tomcat (manually or automatically) * Test And I never have to worry about getting the most recent JAR files -- the deploy target took care of that for me as it was copying all my stuff into the webapps directory. It's even easy to parameterize build.xml so that developers can pick and choose which version of dependent JARs they want, or use defaults. The process of building Tomcat itself (with lots of external dependencies) has convinced me that it's scalable to larger projects as well. One final benefit -- creating the production distribution is now just a matter of JARing up the deployed webapp directory into a WAR file, since you've been developing all along in the same directory structure that you're going to deploy.

Well, the answer IS of course no... :) If you imply such a configuration mechanism (like specify a classpath for every web-application) there might be issues from when you move stuff around (like, from your classpath, to WEB-INF/lib), especially in terms of security and class loading issues. I believe that it can be easily solved by putting down some symlinks in your WEB-INF/lib, so that when you jar up the final release you don't even care what you need to copy over or not... Pier I find that a deploy target in my build.xml file, which assembles the web app in Tomcat's webapps directory (including copying JARs that are needed) solves this kind of pain for me. You're absolutely right that the author of a non-web JAR that you're using shouldn't be responsible for pushing JAR files to wherever they are being used -- it should be the responsibility of the user of that JAR to pull as needed. Ant's copy task is smart enough to skip the copying if the JAR file didn't change, so it's still pretty fast. Now, my webapp development loop goes like this: * Edit * ant compile * Fix compiler errors and loop back * ant deploy * Restart the webapp in Tomcat (manually or automatically) * Test And I never have to worry about getting the most recent JAR files -- the deploy target took care of that for me as it was copying all my stuff into the webapps directory. It's even easy to parameterize build.xml so that developers can pick and choose which version of dependent JARs they want, or use defaults. The process of building Tomcat itself (with lots of external dependencies) has convinced me that it's scalable to larger projects as well. One final benefit -- creating the production distribution is now just a matter of JARing up the deployed webapp directory into a WAR file, since you've been developing all along in the same directory structure that you're going to deploy.

By looking at the source code, I have found a workaround to stop Tomcat 3.3

Instead of using java -classpath tomcat.jar
org.apache.tomcat.Main -stop
use: java -classpath stop-tomcat.jar org.apache.tomcatStopTomcat -ajp12

Tomcat 4.0 behave the same. Only 3.3 is different. I still don't know if it
is a bug or a feature ... :)

Subject: [repost] Re: Limitations in using a different Ajp port than the
standard ? (WAS Re: SAAAM! :))
Hi,
I would like to use different ports than the standard Tomcat ones. For the
HTTP listener, it works fine. However I am having trouble for the Ajp
listener which is used to stop tomcat. The issue is the following :
* When I start Tomcat I use my own server.xml file which is located in my
own directory (I start Tomcat using the -config switch). In server.xml I
also set the ContextManager home to be my own directory. So Tomcat
generates
an ajp12.id file in _that_ directory (and not into Tomcat home directory,
which is normal and fine). The tomcat home directory is set to be the
directory where I have installed Tomcat.
* No, when I want to stop Tomcat, it seems Tomcat looks for an ajp12.id
file
but in the ${tomcat.home}/conf and _not_ in the directory defined in the
ContextManager home or where my server.xml file is.
In other words, it seems it is not possible to start 2 instances of Tomcat
and only stop one running instance (the one with the different ajp port)
by
using only one Tomcat installation ?
Is that a bug, a feature or have I forgotten something ?
Please note that it only fails on Tomcat 3.3 (I have tried it on 3.3-b1
and
on the nighlty build of 2/8/2001). It works fine on Tomcat 3.2.1 and on
Tomcat 4.0.

Here are a few things to think about with this approach. * Tomcat 3.2 (and above) let you run web apps under the control of a Java security manager, so you can grant fine-grained access to system facilities to your apps. Any JAR files that are placed in the Java extensions directory ($JAVA_HOME/jre/lib/ext) receive the same permissions as all the core JDK classes -- something you may or may not want for application classes. * (This issue applies to JARs in $TOMCAT_HOME/lib as well). Not all JAR files will work when installed in a shared directory. In general, containers will create a classloader that makes these classes visible, and then make that classloader a parent of the classloader for each webapp (the one that loads classes from /WEB-INF/classes and /WEB-INF/lib). The problem happens when the shared JAR needs to create a new object of a class that is in your webapp's classloader -- unless it is programmed specifically to deal with this situation, the shared class will get ClassNotFoundException errors. * In some environments, web apps need to use different versions of the same classes (for example, different versions of the same XML parser or JDBC driver) within the same VM. Placing JAR files here makes it difficult or impossible to support different versions. * If you are developing web apps to be packaged and deployed as WARs, you should prefer to include all required JARs inside (so that it is self contained). This will minimize install hassles for your users. Depending on the user to also install external JARs in the right place makes life harder for them. * On the other hand, if you need these classes in more than one web app, placing the JARs in $TOMCAT_HOME/lib or the extensions directory does save a little bit of memory.

Also, in order to avoid mixing user-configuration and automaticly generated files, all generated files go to conf/auto/ ( there are other issues/ideas on this, but for now this should be the first step ).

Re: Virtual Hosts on IIS Tomcat
On Fri, 3 Aug 2001, Knaggs, George R wrote: Mr Shachor / Tomcat-User, I hope you don't mind this email but I've been unable to find any information on how to configure IIS with Tomcat using a Virtual Host where the context path / URI is the root (http://one.domain.com/ and http://two.domain.com/). I have more than one virtual host on this server and the uriworkermap.properties doesn't mention anything about configuring more than one host using the same uri /servlet/*. The tomcat-iis-howto discusses a similar setup but the contexts have different URIs (/examples/* and /webpages/*). There is work going on to fix this in jakarta-tomcat-connectors. One workaround is to just forward all /servlet/* to tomcat, and configure virtual host on tomcat. Of course, the problems are very complex if you want static files served by IIS, it can't be done without few fixes in mod_jk. I've also had trouble installing the isapi filter for an additional web site using the IIS management console. It doesn't seem to be able load the filter a second time. Is there anything that has to be configured differently for installing the filter on a second web-site on the same web server. AFAIK you need a single instance of the isapi filter. The filter should deal with virtual hosts - unfortunately the code is not yet completed. If you know some C - you're wellcome to contribute :-) Can you please tell me if this is possible and if there is any documentation on how to set this up. I've configured this many times with Apache but I'm locked into using IIS4.0 inorder to use a different ISAPI filter that provides single-signon features used at my company. Sorry, I don't use windows. Integrating authentication mechanisms of server and tomcat is very difficult, planned for a future version of jk. ( probably ajp14 ) Costin

RE: Servlet/ Database Conenction Persists Question
Amos, Forgive if I've misunderstood but I get the impression you are not clear about the servlet lifecycle. The init method will be called once. (when exactly is dependant on your servlet engine but it will be before any client requests) You then have a single servlet instance which handles multiple requests - each of which will be handled by a seperate thread. (I'm simplifying a bit because some servlet engines will create a servlet instance per request in implementing the SingleThreadModel but leave that to one side just now) It is the responsibility of the servlet engine to call destroy() Typically when the servlet engine is shutdown. So basically your servlet is running for the same period of time as the servlet engine. For the lifetime of your servlet engine you would only expect init and destroy to be called once for each servlet. It is not like CGI where each request fires up a process to run a new instance of your program.

Andrew, Thank you for your response. I appreciate you clarifying the topic, nevertheless it seems to me a little troubling to assume that the servlet should only be destroyed by the servlet.

In Microsoft Access for example I cannot enter design view if a servlet has an existing connection.

Servlet Through Apache Slow only on local machine
Hi, I just installed apache 1.3.20 and tomcat 3.2.3 on a Windows 2000 machine. The tomcat servlet examples are fast if I access them directly through tomcat ( port 8080 ), but extremely slow when I access them through Apache. The funny thing is that it is only slow when accessed from browser on the same machine, it works fine when accessed from another machine. I checked the mail archives and saw something about changing the log level to error in mod_jk.conf but that didn't make any difference. Any Ideas? Thanks, Gary [EMAIL PROTECTED]

Would this be possible? Your problem seems to be more of a lack of distributed systems and client/server programming knowledge in general rather than the specifics of Servlet programming. A desktop application is just that, it runs on a desktop when a user needs it, etc. A web SERVER, however, is always on, always waiting for users to give it actions to perform. I've dealt with this type of problem in two different ways (and there are probably others out there). The first is to shut down Tomcat. Generally if I'm changing the schema then I'm performing a long lasting update that might take a few minutes to a few hours. During that time I don't want users working with a partially updated database, usually with either new or old code. The second way that I have dealt with this problem (and possibly more applicable in your case) it to encapsulate the database access into an underlying component with static fields. Then, I create a database controller servlet. This servlet usually takes request like controller?action=startup or controller?action=stop that would create the database connection pool, drop all the actives (you need to think about what to do if something is using the database here), reload configuration, etc. Another thing you need to be warned about is using Access. I assume you are using it because you mention it. This is a pretty bad choice for a server-based product for a number of reasons, not the least of which deals with the concurrency problems of the JDBC-0DBC bridge (you can find more information about that either in the archives or on Sun's Bug Parade).

RE: Servlet/ Database Conenction Persists Question
If you don't want a database connection to persist, just don't keep it around. Your first option is to create it each time in your service routine, and close it before you return. A second option would be to keep it around (e.g., in a session attribute), and create it in your service routine only if it doesn't already exist. Then, you define a particular URL parameter: when you get that parameter, close the connection and null out the reference. There's no reason to change the definition of init() for this particular case. -- Bill K. -Original Message- From: A.L.
