Re: apache question
Hi everyone, I'm sorry for not providing the system informations earlier, the linux I'm using is centos 2.6.18 and the apache tomcat is 7.0.4 java is 1.6.0_22 I know the difference between apache tomcat and apache httpd, I need to configure apache httpd to server as a proxy, I just want to know is apache httpd comes with apache tomcat when you download it, as I mentioned before I see there is httpd in /etc but I don't see apache in the /opt so does that means I need to download apache ? and my second question is how to upload a html ( embedded with java script )web page into apache ?

Lava, you have not told us which version of Tomcat (or Apache httpd) you are using, on which exact platform, with which version of Java, nor anything really about where these different packages come from or how or where they are installed. You also seem to be relatively confused about what Apache Tomcat and Apache httpd really are, and how they can communicate with eachother, or even if they need to communicate with eachother and why. There are probably 30 different types of Linux, and several hundred types of boxes on which to run it.

Re: apache question
so that means I already have apache httpd but I need to install mod_jk connector correct? On Wed, Feb 2, 2011 at 1:19 PM, Dave Evans dsevan...@gmail.com wrote: In centos the file /etc/httpd/conf/httpd.conf should be the configuration for the Apache HTTP Server. For information on that configuration please write to the apache users list. One quick tip, assuming you have no virtual hosts set up, the DocumentRoot directive will tell you where to put your html files. To pass java server requests to Tomcat you can install mod_jk. You should be able to find an rpm to do this for you. Once it is installed, you'll need to use JkMount directives in the httpd.conf file to tell Apache Http Server which requests to pass to Tomcat, for instance: JkMount /*.jsp ajp13 # pass jsp file requests JkMount /*.do ajp13 # pass struts app requests JkMount /manager/* ajp13 # pass manager app requests The ajp13 token above is the name of a worker configured in your {tomcat root}/conf/workers.properties file.

Re: HTTP status 404
Hello everyone, Thanks for the replies I really appreciate your feedback I have the structure as the following webapps | filename |- filename.htm *|-*WEB-INF |- web.xml |-META-INF |-context.xml after having this structure,I use the following command CATALINA_BASE/webapps/filename/ jar -cvf filename.war *.* then I deploy the file in the tomcat manager and I have the following error HTTP status 404 description the requested resource (/filename/)is not available I assumed that I don't need the java classes and lib in the WEB-INF since I'm only having single html file with java script, Do you think I need any ? if so how do I know which files I need ?

HTTP status 404 description the requested resource (/filename/)is not available Hi. Except the 404 error which your are getting, not much above makes any sense at all. So it is better to forget all that, and start new. You really have to learn to walk before you can run. First, consider the directory structure of a standard Tomcat installation : (CATALINA_HOME) (=CATALINA_BASE) | |- bin (tomcat programs and scripts) |- conf (configuration files) |- lib (global library files) |- logs (logfiles) |- webapps (* web applications *) |- ROOT (the special, top-level, default web application) |- app1 (a web application) |- app2 (another web application) |- ... |- lastapp (another web application) In the above, (CATALINA_HOME) represents the top directory of your Tomcat installation, the one under which the rest of Tomcat is found. For example, on your system it may be C:\tomcat or C:\program files\Apache Software Foundation\tomcat6.0 or /usr/share/tomcat6 or /usr/local/tomcat6 or whatever. The webapps sub-directory is what is important for you now. That is where you will put web applications, composed of static html pages (with or without javascript in them), JSP pages (special html pages with embedded Java code), java servlets (compiled java applications), etc.. The ROOT web application is special. It is the default application. When you use a URL like : http://yourserver.yourcompany.com/abc.html Tomcat is going to look for abc.html under the webapps/ROOT directory. The other subdirectories under webapps are each one separate web application. To access for example the application named app1, you will have to use a URL starting with http://yourserver.yourcompany.com/app1/; For example, if you place a html page named xyz.html in the subdirectory (CATALINA_HOME)/webapps/app1, then the URL to call it up will be http://yourserver.yourcompany.com/app1/xyz.html Under such a web application directory like ../webapps/app1, there is also a structure. It looks like this : (CATALINA_HOME) (=CATALINA_BASE) |- webapps (* dir, top of all web applications *) | |- app1 (dir, contains the web application named app1) - public files (html etc..) - WEB-INF (directory) |- files (private) |- web.xml (configuration file for the application) |- classes (dir.) |- compiled java classes, like servlets |- lib (dir) |- java libraries for this webapp - META-INF (dir.) |- context.xml (more settings for the application) Basically everything under app1 is optional. Tomcat will supply a default if needed. Of course, you will want at least one file under there, to make the execise meaningful. What is in the sub-directories WEB-INF and META-INF, can never be obtained directly by a browser. Tomcat will not allow it. So if you enter the following URL in the browser : http://yourserver.yourcompany.com/app1/WEB-INF/something Tomcat will respond with an error, even if something exists. But to start, I suggest that you just - stop tomcat - create a new sub-directory under ../webapps/, for example myapp. - under that subdirectory, place a file called myfile.html - verify that the ownership and permissions of these files are such that the Tomcat user can read them - start Tomcat - in the browser, enter

Hi Mark, I have changed my web.xml file to the one you send me and added the welcome-file-list so I will not need to navigate to localhost:8080/filename/filename.htm, I changed the index.htm to filename.htmthen I navigated to localhost:8080/filename and it didn't work , I also copied the filename.war file to the webapps and nothing changed however after changing the web.xml file when I navigate to localhost:8080/filename/filename.htm the filename pops up, on the manager side its says running but the session stays zero so to be honest I'm kinda confuse is it working now ?if I changed the web.xml shouldn't be working on localhost:8080/filename/ ?

Change index.html to filename.htm (if this is what you want your welcome file to be). Then navigating to: localhost:8080/filename/ will work. If you want to create a war file, do the following: 1. Change to the directory filename 2. jar cf ../filename.war . 3. cd .. 4. jar tf filename.war (should give you the complete structure) One way to use the war file: 1. Copy filename.war to $CATALINA_HOME/webapps If running, the default configuration of Tomcat will explode the war file and you will see a filename directory in $CATALINA_HOME/webapps along with filename.war.
