Re: website hosting
Go to the directory where Tomcat is installed. Under the Tomcat directory there will be a "conf" sub-directory. In the "conf" directory there will be a "server.xml" file. In the "server.xml" file you can configure many aspects of Tomcat, including the port on which Tomcat listens. * Barry KimelmanToronto, Ontario, Canada ---Original Message--- From: suri.jagadish Date: 05/14/05 11:06:30 To: tomcat-user@jakarta.apache.org Subject: website hosting Hi I need to host a website using the tomcat Webserver How do I configure the tomcat for the default port80 for answering the http request for the ip address in the net I had already done it using (Microsoft) IIS.

I can then successfully run theproject by visiting the appropriate URL in my browser. However when I make a change to my project either by recompiling some of my Java source code or by modifying some of JSP and/or HTML files, how do I get Tomcat to "recognize" these changes ? If I run the command "ant reload" from the DOS command line, when Irerun my application I do not see my changes.

Tomcat rookie needs help building application
I need help building my 1st Tomcat application. My system is a Windows XP PC. My version of Tomcat is 5.5.8. I have tomcat installed under the directory C:\Tomcat5.5 I have verified that the installation of Tomcat was successfull by visiting http://localhost:8080. Once at the test page, I also ran some of the JSP examples to verify that everything was working correctly. My problem is that I can't build an application successfully. I have searched the Tomcat documentation and several mailing list archives, but I have not found any documentation that states, "This is how to build a Tomcat application". I have organized my source code as described/recommended in the Tomcat documentation. I did have some success with Tomcat 5.0.16 under Linux Redhat9 a year ago, and as I recall, you compiled your application from the command line using the "Ant" utility. So I changed my current directory to the toplevel of my project and issued the command "ant compile". I received the following error message : BUILD FAILED C:\barry\myproject\build.xml:146: taskdef class org.apache.cataline.ant.DeployTask cannot be found Line 146 of my build.xml file is as follows : taskdef name="deploy" classname="org.apache.catalina.ant.DeployTask"/ I searched the JAR files under my Tomcat installation and found that the JAR file located at C:\Tomcat5.5\server\lib\catalina-ant.jar conatins the "missing" class. According to the Tomcat documentation that I read, JAR files placed under $CATALINA_HOME/common/lib are available both to web applications and internal Tomcat code. So I copied the JAR file under that directory and once again attempted to build my project/application. However, I received the same error message What do I need to do in order to build/compile my Tomcat5 project ? Is there a "How to build a Tomcat5 Project" document ? Please help a confused rookie. * Barry KimelmanToronto, Ontario, Canadaemail :[EMAIL PROTECTED] , [EMAIL PROTECTED]

Re: Deployment: admin vs manager
I amusing Tomcat 5.0.16 under Linux Redhat9. I am relatively new to Tomcat myself but I have found that it is easier to use the "ant" command from your command line prompt to install (ie. deploy) a Tomcat application. In either case I use the command "ant dist"command to compile my application and prepare a .WAR distribution file. Next I simply use the ant command line "ant install" to deploy my application, If you want to access the Manager application via your browser you could always enter a URL like the following : Http://localhost:8080/manager/deploy?path=/appnamewar=file:/home/bkimelman/application-directory/dist/appnameappversion.war It seems to me that the easier wau to go is to use Ant from your command line. * Barry KimelmanWinnipeg, Manitoba, Canada ---Original Message--- From: Tomcat Users List Date: Sunday, February 29, 2004 11:39:31 AM To: [EMAIL PROTECTED] Subject: Deployment: admin vs manager Should I deploy apps with the manager or admin interface? With the manager interface, it is easier, because I can also specify my application.xml and therefor do not have to configure my datasources manually. But, using the manager interface, everytime I restart Tomcat, I have to re-install the apps also - the context is lost (the applications are not stored under the webapps dir - the sysop wants everyone's apps in his own homedir). So which interface must I use for deployment and how can I overcome the problem mentioned above? Thanks __ Do you Yahoo!? Get better spam protection with Yahoo!

Problem reloading Tomcat 5.0.16 application
My system is Linux Redhat 9. Iam running Tomcat 5.0.16 from a binary distribution. I can successfully compile and install my application. The JSP page works fine. However, when I make a change to the Java class used by the Bean referenced in the JSP file, then issue a "ant reload" command (which succeeds) and again execute my tomcat application, I get the output from the old version of the application. I resorted to "undeploying", recompiling and installing to get Tomcat to run my updated code. How can I get Tomcat to recognize the changes I make to my own personal class files ?
Re: deploying parameters using catalina.ant
I myself was just recently able to successfully install application into Tomcat 5.0.16 using the ANT utility.
1st you need to properly setup your build.xml file (a sample can be obtained from the Tomcat web-site).
Then you need to modify the sample build.xml file to suit your needs.
* modify the "project ..." descriptionto describe your application
* modify the property . descriptions to suit your application and Tomcat environment :
eg. set a value for "app.name" , "app.version" , "catalina.home"
I found that I also had to modify the value for WAR file description on the "install" target description
in order for the "install" to work properly. For my case when I changed the WAR description to
war=file://${dist.home}/${app.name}-${app.version}.war
I was successfully able to execute an install.
Also you should define a "build.properties" file in your home directory that at the very least defines values for the properties :
manager.username
manager.password
manager.url
You should also modify the "tomcat-users.xml" file in the "conf" directory og your Tomcat installation.
You should define "roles" for "admin" and "manager".
You should also define a "user" that has the "admin" and "manager" roles assigned to him/her.
After all this you should be able to run the "ant install" command to deploy your application.
I hope all this helps.

Subject: deploying parameters using catalina.ant
hi,
is there anybody out there that can help me on this subject. This is my 3rd
message. Am asking something wrong?
I am trying to use the command org.apache.catalina.ant.DeployTask in ANT to
deploy an application into TomCat using a context xml file. It seems it is
mandatory to issue the path parameter but with a context xml file that
should not be necessary.
I looked on the Tomcat site and I could not find anything on this topic. Can
anyone help me?
Where can I find information about the catalina-ant.jar?
my best regards,
Hernâni

Newbie needs help with Tomcat 5.0.16 application install
My OS is Linux Redhat9.
I have downloaded and installed Tomcat 5.0.16 from a binary
distribution.
I created a build.properties file in my home directory as follows :
manager.username=bkimelman
manager.password=foobar
manager.url=http://localhost:8080/manager
I can successfully use ant to compile my tomcat application.
I can successfully use ant to prepare a WAR file for distribution.
I tried some of the sample applications that came with the tomcat
installation and they all worked OK.
I successfully used the manager webapp (via the Mozilla browser)
to get a listing of all applications :
http://localhost:8080/manager/list
When I tried to install my webapp using ant I received the following
error message :

However, when I used the manager webapp via the browser as follows :
http://localhost:8080/manager/deploy?path=/tomcat1;
war=file:/home/bkimelman/tomcat1/dist/tomcat1-1-dev.war
I was successfull in deploying my application
(and I was able to run my application).

Newbie needs help with Tomcat5.0.14
I recently installed Tomcat version 5.0.14 from a binary distribution download. My system is a laptop running Redhat Linux 9 (kernel release 2.4.20-8). I untared the tomcat tar-file and everything looked OK. I started the Mozilla browser and was successful in visiting http://localhost:8080 I followed the instructions in the sample build.xml file and was able to successfully compile my application. I wasn't able to install my application from the commandline using ant. I was able to use the Mozilla browser and use the manager webapp to deploy the application. Why can't I usant from the commandline to deploy/install my application ? It then occurred to me that the other TAR files comprising the Tomcat 5.0.14 binary distribution had something to do with my problems. I untar'ed those Tarfiles. The contents after I untared those files looks something like the structure of a Tomcat5 application; they have build.xml files, etc... But what do I do with these other 2 structures : deployer and embed ? I tried running ant to install the deployer, but with no luck. Any help would be greatly appreciated.
Newbie with problems during tomcat application install
My system is a laptop running Linux Redhat 9.
I have installed Tomcat 5.0.14 from a binary download distribution.
The sample applications work perfectly.
I can compile my application with no problems.
But when I issue the ant command ant install I receive the following
output :
___
Buildfile: build.xml
prepare:
compile:
install:
BUILD FAILED
/home/bkimelman/tomcat1/build.xml:365: Could not create task or type of
type: deploy.
Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'deploy'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and optional.jar is absent
Fix: look for optional.jar in ANT_HOME/lib, download if needed
- The task was not built into optional.jar as dependent
libraries were not found at build time.
Fix: look in the JAR to verify, then rebuild with the needed
libraries, or download a release version from apache.org
- The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
and needs to be declared using taskdef.
Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath
Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.
Total time: 13 seconds

I followed all the instructions in the sample build.xml file with respect
to copying files into the appropriate locations.
I then reran the ant command with the debugging option ant -d install
According to the debugging output from ant, the compilation classpath does
indeed contain a reference to the JAR file which contains the DeployTask
class file.

Here is the relevant portion from my build.xml file. I created this file by
copying the sample build.xml file and making the appropriate changes.
340 !-- Install Target

344 The install target tells the specified Tomcat 5 installation to
dynamically
345 install this web application and make it available for execution. It
does
346 *not* cause the existence of this web application to be remembered
across
347 Tomcat restarts; if you restart the server, you will need to
re-install all

349
350 If you have already installed this application, and simply want Tomcat
to
351 recognize that you have updated Java classes (or the web.xml file),
use the
352 reload target instead.

354 NOTE: This target will only succeed if it is run from the same server
