Re: Tomcat Problem
Hello: Please post queries related to Tomcat's usage to the Tomcat-user mailing list. You will have a bigger audience there to help you get started with Tomcat. 1. Have you read the application developer's guide ? http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/index.html It is also installed along with the tomcat that you are running as part of the tomcat documentation, accessible via http://localhost:8080/ Read this doc, and you will learn exactly where to place classes (e.g. not in the bin folder). 2. To get started quickly, I suggest you make a copy of the examples webapps, and start adding jsps there. 3. Does your bean belong to some package ? e.g. foo.bar.MyBean 4. Upper/lower case matters. Are you typing the class name in the correct case ?

Hi: I do not have Windows, I use Redhat Linux 9 at home. I just read the docs at http://jakarta.apache.org/tomcat/tomcat-5.0-doc/setup.html From what I read in the third para titled Java location, I infer the setup tries to detect the location of the JVM. Why don't try the following: 1. Uninstall Tomcat. 2. Set the JAVA_HOME environment variable. 3. From a freshly opened command window, issue the command echo %JAVA_HOME% You should see the location of JAVA_HOME being displayed. 4. Now run the Tomcat installer, and check if JAVA_HOME was made use of. The Tomcat installer is written with NSIS (excellent, I use it too). Without the NSI script in front of me, the only problem/bug I would expect would be that the installer reads the JVM path from the registry before checking the JAVA_HOME, and that your JVM folder does not have tools.jar. -- Sriram --- Gerald Stampfel [EMAIL PROTECTED] wrote: Got it !

[5.0.14] Does it have the logs folder ?
Hello: With the votes going on for 5.0.14, I have a question. I'm using Redhat 9. When I installed the 5.0.14 tgz and ran the startup script, I had faced a problem with the startup script not being able to create the $CATALINA_HOME$/logs/catalina.out file using the touch command. As it turned out, the tgz did not have the logs folder, and the man for the touch page says that touch does not create a folder if it does not already exist. An experiment verified this too. I guess the fix involves merely bundling a logs folder. I've posted a Bug in Bugzilla, but I have not seen any mention of a fix on the changelist for 5.0.14.

I have another question on the same subject for the list at large. Now that my application can create it's own contexts for my webapps to run inside of, is there a way that my JSPs and Servlets can modify and make use of objects that are instantiated inside the application? Sure they can. If you're not loading your Contexts via special classloaders, then it's as simple as getting an instance of your application's objects and making use of them. See an example that I've mentioned below. If you're using custom classloaders to load Contexts in separate classloaders, you need to give information on the Classloader hierarchies that you're using. For example, my application is multi-threaded and it starts Tomcat, retrieves some data from the database and performs a few other functions. The reason why I'm embedding Tomcat is to give my application a web front-end. Could anyone provide some insight as to how I can make this happen, and perhaps provide some code samples? a. Get hold of your application's objects via JNDI. b. Create a class called the Environment, and register your application objects into this class. Such a class could be just a wrapper for a Hashtable. Make this Environment class a Singleton. Next, from within the contexts, access this Environment singleton, and go on to access your application objects. e.g. To share a data source between a Context and your application, you might try: // in your application Environment env = Environment.getInstance(); Connection connection = createConnection(); // returns a connection to a database. env.registerObject(DataConnection,connection); // In your web application Environment env = Environment.getInstance(); Object anObject = env.getObject(DataConnection); if(anObject==null) throw new Exception(No Data Connection in environment !); Connection connection = (Connection) anObject; connection.execute(select * from sales); Thanks. -- Robert Charbonneau [EMAIL PROTECTED] -- -- Sriram Object Edge Software India Pvt.

Re: Unable to find servlet class after reload
Hi: Just a blind shot (I've not used Struts yet). Do these load-on-startup servlets require anything to be initialized in struts ? Does Struts require initialization by the web app developer ? If so, perhaps you need to somehow ensure that such initialization takes place before you load your servlets ? Separately, what exactly do you mean by reloads cause the errors ? Does everything work fine when Tomcat is started ?

Re: Embedding Tomcat Continued...
Hi: I think you do not have tools.jar in your CLASSPATH. JAVA_HOME is used by the startup scripts when you use regular Tomcat. Since you've used Embedded to embed TC, the startup scripts do not come into the picture, and the JAVA_HOME is pretty much useless actually. Try placing the tools.jar file in the CLASSPATH and then run your application. Important: If you're invoking your aplication via a JAR file, you need to specify the tools.jar in the CLASSPATH attribute of the Jar's manifest.

RE: Embedding Tomcat with Java App and JRE only
This is indeed the ight place. But please check the mail archives first. I'd had to Embed Tomcat way back in Dec 2001 - Jan 2002, and had faced lots of problems then, with not a single question of mine being answered. However, I'd posted some of my lessons learnt at around that time. I've replied to some other posts on Embedding Tomcat over the past months, you should get these on the mail archives too. I'm not at all aware of changes in Tomcat 4.1.x, but here are some of the problems that I'd faced: 1. Embedding Tomcat itself. Browse the source, trace how Bootstrap and Embedded work, and you'll learn that tomcat, is actually Catalina for Servlets, Jasper for JSPs, Connectors for HTTP services, etc. I first figured how the Digestion works (where server.xml is used to assemble together the Engine, the host, the contexts, etc), and then wrote something myself on the lines of Embedded. You need to understand just how Embedded works, and you'll have a working ServletContainer running. 2. Accessing LifeCycle events With 4.0.1, the LifeCycle Interface has just the starting and stopping events. I think 4.1.x now has starting, started, stopping and stopped (or something along those lines). Since I did not dare to alter the LifeCycle Interface myself (break compatibility with the Tomcat Developers, etc), I had to resort to a check after the entire server came up. 3. Getting Jasper to work right. I had to start my app via an executable Jar, and this changed the classpath. (Remember, I was not using the startup scripts). I chose to alter the java.class.path environment variable myself before starting to assemble the Catalina components together. If you're loading via a Jar too, then you'll need to use the JarFile API, access the manifest, used the Classpath attribute from the manifest, and assemble together a classpath again. (NOTE: 4.0.1 uses the javac compiler. 4.1.x uses Ant, so I have no idea on what to expect here.) I used the Visual Age for Java IDE then, so that helped a lot (The scrap book was the best aid I had). I think Eclipse gives you similar functionality, so you could perhaps experiment with snippets of code yourself. A lot has changed since 4.0.1. Browse the source, read the Javadocs, and you should have a good understanding in about a week's time. There was also a post recently of someone writing a book on How Tomcat works, you might want to give those PDF chapters a try.

Re: Classpath problem with Tomcat running in Embedded mode
Hi, If you're calling Bootstrap.main(), please also have a look at the source code within Bootstrap. You'll find that Bootstrap just sets the ground for the Catalina classes...It creates a classloader hierarchy, with classloaders for classes visible to just Catalina, and for visibility between both Catalina and Webapps. Each webapp has a classloader to itself. What you should do instead is have a look at how Embedded works, and do something like that yourself. This may not be the intended approach behind supplying Embedded, but this is how I've bundled Tomcat 4.0.1 for a Swing based app I had to once develop. -- Sriram --- sandeep arshanapally [EMAIL PROTECTED] wrote: Thanks for your reply.

On Resin, Tomcat and Apache.
Hi all, I saw the past few days' posts on resin vs tomcat, and tomcat vs apache. I just went over to resin's site, and here's what they have to say: Resin includes a full-featured HTTP/1.1 web server dedicated to serving fast Java dynamic content. While Resin is tuned for dynamic content, its static file performance matches or beats Apache's static performance. Many, if not most, sites will use Resin's web server for all their web server requests. But if you go over to http://www.caucho.com/articles/jsp_benchmarks.xtp;, which is available as a link on the same page, you'll notice that they're talking only about serving JSPs. And they use JDK 1.1.7, and they compare with JServ, and not Tomcat. I can't comment on JServ, since I'd used it for just day before I discovered Tomcat. I remember coming across a post by Craig (in either of Tomcat-user or Tomcat-dev) that with today's JDKs reflection etc is very fast, and Tomcat by itself is very fast. For a web-solution that we gave to a bank, I built a app that contained Embedded Tomcat 4.0.1, and the customers are satisfied with the performance. And with the new Jasper and the whole lot of improvements that have been, I'd say that Tomcat today is much more improved than what it was a year ago. Sriram __ Do You Yahoo!? Yahoo!

Re: Log4j initialization problem
Hello,
Here's an idea, thouh I'm not sure it's a clean one...
1. In the contextStarted, get hold of the real path from the servlet context.
Let's say you get /var/tomcat/webapps/myapp/.
2. Set this to a System property
e.g. String currentWebAppPath = /var/tomcat/webapps/myapp/;
System.setProperty(myapp.LogFolder,currentWebAppPath+logs;
3. In the log4j.properties file, specify the file path as
log4j.appender.A1.File=${myapp.LogFolder}/LogMessages.txt
4. You'll now find all your logs being stored to this folder. You have to have
created this folder first ;-) You could always use File.mkdirs() in the
contextInitialized...
Now when you change your webapp's foldername, you'll find the logs going to the
right location...
Note: I don't have access to my comp, so there might be some syntax errors,
etc...
By the way, have you considered that the servlet container need not expand your
app's war ? I run my webapps this way lots of times. If the .war is not going
to be expanded, then the logs wont go to the sub folder...
And yes, you should post log4J configuration queries to the log4J interest
list, after first searching the archives ;-) There's active development going
on right now, and you just might get ideas from the developers themselves.

to change the log4j.properties entry whenever the webapp is moved to
another context directory or installed on another machine which might

So is there a way to get the log file to be created and placed under its

Re: Log4j initialization problem
Hello,
I don't have access to my computer right now, but here's roughly what I do to
use log4J within my Servlet 2.3 API compliant webapps.
1. Create a properties file called log4j.properties
2. Place this in WEB-INF folder.
3. Write a ContextListener and in the contectInitialized method, access the
servlet context. Make sure you place this Listener implementation along with
your other classes and that you add an entry for it in web.xml
4. Ask the servlet context to get the following resource as a stream
e.g. InputStream is =
servletContext.getResourceAsStream(/WEB-INF/log4j.properties);
5. Create a properties file that'll initialize with this property file.
Properties properties = new Properties();
properites.load(is);
is.close();
6. Now pass this newly initialized properties object to the
PropertyConfigurator...
That's it.

The log4j stuff is being initialized/configured by a servlet which has
the following init() method:

public void init()
{
// gets the base directory to use, from the web application's

String prefix = getServletContext().getRealPath(/);
// this looks in the web.xml for the initialization file

// if the log4j-init-file is not set, then no point in trying
if (file != null)
{
// apply the configuration specified in the initialization
file
PropertyConfigurator.configure(prefix + file);
}
}

The above mentioned Log4j initialization servlet is being called at
loadup time by virtue of the following entry in my web.xml:
-
servlet
servlet-namelog4j-init/servlet-name
servlet-classmyapp.servlet.Log4jInit/servlet-class

Because I have three separate webapps which should all have their own
log files I would like to have the log files created in the separate
webapp directories, or perhaps better yet in a logs subdirectory under
each webapp directory. For example if a webapp is under
/var/tomcat/webappps/myapp then I would like for the log file to be
created as /var/tomcat/webapps/myapp/LogMessages.txt or as
/var/tomcat/webapps/myapp/logs/LogMessages.txt. How can I get this to
happen ? Should I make a change to a log4j.properties entry, or perhaps
I'm making an error in my log4j initialization servlet's init() method
by referencing the wrong path in the getRealPath() call ?
Any suggestions will be appreciated. Thanks in advance.

Here's how you check the JAVA_HOME env variable. (Was :Re: Solution to sun/tools/javac/Main - Problem and some Critique about classpath)
--- Michael Kastner [EMAIL PROTECTED] wrote:
Siram,
thank you very much for your reply. I think I wasn't specific enough. To put
my critique in a nutshell: if I set JAVA_HOME in the environment, there
oughtn't be a need to copy tools.jar in a /lib directory of tomcat.
Of course. The tomcat startup scripts have been written to help us achieve this
:-)
There should neither be a classpath (which you explained are ignored by
tomcat) nor should there be any script settings necessary. The setting in
JAVA_HOME should simply be sufficient to make the jdk's jars available to
tomcat.
Umm.. there is indeed no need to worry about the CLASSPATH, actually..The
JAVA_HOME setting is indeed sufficient.
But that is not the case. Without copying tools.jar to
{tomcat_root}/common/lib and/or {tomcat_root}/server/lib it's not recognized
by tomcat and an exception is thrown. Was I clear?
You really need to check that your JAVA_HOME environment variable is pointing
to the correct folder.
Try this on a command prompt (these work on Windows, you could try Unix
equivalents)
if exist %JAVA_HOME%\lib\tools.jar echo found tools.jar
This will display the string found tools.jar in on the screen, if your
environment variable is indeed set correctly.
On my NT 4 system, this works right regardless of whether the JAVA_HOME env
variable points to a directory with spaces in it or not. So, even if the JDK is
installed at, say e:\program files\Javasoft\jdk, the command and the
catalina.bat scripts will work OK.
if not exist %JAVA_HOME%\lib\tools.jar echo could not locate tools.jar
If you see the string could not locate tools.jar sicplayed on screen after
running this command, then your JAV_HOME env. var. is not set correctly.
Also, do mention the Tomcat release that you're testing with.
I have Tomcat 4.0.1 running on Sun's JDK 1.3.1 and my OS is WinNT 4.0 with
Service Pack 6, and once I set JAVA_HOME, tomcat works out of the box for me.
Which JDK release are you using ? Does it ship tools.jar in JAVA_HOME\lib ?
Because that's where the tomcat startup scripts look for this file.

Re: Solution to sun/tools/javac/Main - Problem and some Critique about classpath
Hello,
for anybody who has been running into this exception when trying to
execute
JSPs:
javax.servlet.ServletException: sun/tools/javac/Main
Heres the solution:
tools.jar is not recognized when it's in classpath
thus it must be copied to
{tomcat_root}/common/lib
and/or
{tomcat_root}/server/lib
The Tomcat startup scripts start up Tomcat in such a way that the existing
CLASSPATH is ignored completely.
They do this by creating another environment variable called _CLASSPATH, which
contains the default CLASSPATH variable's values, if any. The startup scripts
then proceed to assemble together a CLASSPATH which is used to start and run
Tomcat. This CLASSPATH contains only those Jars that are present in the Tomcat
sub-directory.
Once this tomcat specific CLASSPATH is created, it is used to startup Tomcat.
Now, the ony other places from where jars/clases might be loaded is the
%JAVA_HOME%/jre/lib/ext folder. The extensions Classloader, which is one of the
three Classloaders that work when the JVM comes up, loads all classes and Jars
that are present in this folder.
If you next use the supplied shutdown scripts, then the default CLASSPATH is
restored, using the values fromthe _CLASSPATH environment variable.
My opinion:
I've been chasing down this problem for three days now, and all I could
find
in the respective mailing list databases was: put tools.jar in the
classpath. But that didn't work. Eventually I found the solution
mentioned
above - as I wrote - after three days.
If the JAVA_HOME environment variable is correctly defined, then the startup
scripts correctly construct a Tomcat specific CLASSPATH environment varialbe
that includes %JAVA_HOME%/lib/tools.jar. If you have such an environment
variable, and yet you have to copy tools.jar to a Tomcat subfolder, then please
check the value of this environment variable. For e.g. I have installed JDK
1.3.1 at e:\jdk1.3.1 on my WinNT 4.0 system, and the value of the JAVA_HOME
environment variable on my system is e:\jdk1.3.1\ (with the trailing
backslash). This constructs the correct CLASPATH for me, which includes the
tools.jar.
Ever since I started working with java and that was four years ago, the
classpath has been a problem in java. I would expect that in the
meantime
the directory structures would be sufficiently standardized and thus
make
_any_ classpath settings unnecassary. Once JAVA_HOME and/or JAVA_PATH
are
set the environment should be defined.
But that's not the case. To make things worse, sometimes like in this
case,
the classpath settings are ignored. Who would have expected that
tools.jar
needs to be _copied_ to some other location? I wouldn't.
While it might be frustrating to those who do not know that their carefully
constructed CLASSPATH is actually ignored by the startup scripts, this can be a
book actually. Quite a few Tomcat users have big unmanageable CLASSPATHs and
jars scattered all over the place, and supporting such setups via this
mailinglist can be a real nightmare.
Because I wouldn't
expect _any_ developer of java and escecially java server applications
to
propose a configuration, where system jars are located in more than one
location. Thus maintenance of the system becomes a nightmare when a
system
update is due.
I just hate when that happens.
The firm that I work for is soon going to deliver a some 6 web apps, all of
which will be running on Tomcat 4.0.1
Because of the way Tomcat's startup scripts work, we are not particularly
concerned with other jars etc that might be added to the system on a later
date. And then what if the customer were to change the CLASSPATH variable's
values ? The way the startup scripts work right now, we are at least sure that
if there are any new Jar files, we know where to place them. And if there are
any conflicts in the future, either there's some foreign jar files in our
Tomcat folder, or in %JAVA_HOME%/jre/lib/ext And no more worries about the
CLASSPATH being changed, etc.
If you'd indeed like the Tomcat startup scripts to refer to your system jars,
then you could customize the file catalina.bat (catalina.sh for unix users) The
place to do your customization is in the section titled
rem - Set Up The Runtime Classpath
You'll see here that the tools.jar is referred by the line
set CP=%CATALINA_HOME%\bin\bootstrap.jar;%JAVA_HOME%\lib\tools.jar
If you'd like to support additional System libraries, say something product
called XYZ which is available at e:\XYZ\lib\xyz.jar,
then you could add a line like this,
set CP=%CP%;e:\XYZ\lib\xyz.jar

Hello,
as I saw in many mailing lists I am not the only one who had the following
problem, so I post a solution here.
Problem:
After installing tomcat 4.01 all example JSPs in the provided applications
work well. But when you try to run your own JSPs in your own applications
you suddenly get this exception thrown:
exception
javax.servlet.ServletException: Servlet.init() for servlet jsp threw
exception
...
...
root cause
java.lang.ClassCastException:
org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
Solution (at least in my case):
I had an xml parser version in my /appname/WEB-INF/lib directory which was
different from the xml parser located in {TOMCAT-ROOT}/common/lib. It seems
that if there is an xml parser located in the app's WEB-INF/lib directory,
then this parser is being used to compile the application's JSPs. And this
leads eventually to the ClassCastException.
The application, where this error occured was originally transferred from
JRUN 3.1 where this behaviour does not occur. On a JRUN 3.1 server the xml
parser in an application's WEB-INF/lib directory is NOT being used to
compile the application's JSPs. However in tomcat 4.01 it is being USED. So
watch out about multiple xml-parser versions!
Maybe this helps some people.
Sincerely
Michael Kastner

Quick guide to a virtual host in Tomcat (Was: server.xml and Catalina)
--- Micael Padraig Og mac Grene [EMAIL PROTECTED] wrote: I sure am having trouble getting an example of server.xml. I bathed! Is the 4.0 server.xml structured about like the 3.2 was? I have looked at the documentation, but I am practically oriented. If someone would show me one copy of a working server.xml with virtual hosting, I would be off and running. But --- no! ;-) Come on, someone, help me out. I just a simple thing. 1. Open server.xml 2. Copy the Host section and paste if again below the original Host section. 3. Change the default values to something like Host name=shrek debug=0 appBase=e:/shrek unpackWARs=true Where my comp is also called shrek, and the web apps for this shrek server will be kept in e:/shrek sub-directory. 4. Copy the ROOT folder from the actual Tomcat/webapps folder to this new folder. So I now have e:/shrek/ROOT. 5. Change the text in index.html in e:/shrek/ROOT to say something else e.g This is my shrek server 6. Update my hosts file to include an entry for this new name for my computer e.g. 192.168.1.219 shrek 7. Test this new entry by trying out ping shrek in the command line 8. Start Tomcat and point my browser to http://localhost:8080/ to see the default Tomcat Welcome page. 9. Next, point my browser to http://shrek:8080/ to see another index page that says, This is my Shrek server. I don't know if this is what you're looking for though. I do not have any DNS and such stuff. -- micael Sriram __ Do You Yahoo!? Great stuff seeking new owners in Yahoo!
