I have this requirement to write a customized module in http server. Newer version of the application uses the APACHE http server and the older version is deployed on IHS (IBM Http Server). I tried googling it but I couldn't find anywhere if I can write a module and packaged it in IHS .Is that possible ? If yes , how ? Do I have to get the code and build it with my module or I can write some extension and plugin into IHS. anything will help , thanks.
Yes, you extend IHS the same way you extend a vanilla Apache HTTP Server module -- with the Apache HTTP Server API.
You can either use binary modules compiled against vanilla Apache, or compile directly against IHS with the inclued bin/apxs script.
For pointers, look at any existing module in the core distribution of Apache, or Nick Kew's Apache Modules book.

I've been researching how to connect Tomcat and apache http server because I will have my web application written in angular deployed in apache http server 2.2 (currently succesfully tested on my own computer, local), and my REST service written in java deployed in Tomcat v6,
and what I want now is that when some component is clicked, to make a http request (like this http://localhost:8080/rest/getCars/20130505) that connects with the servlet and use the json provided to use the information provided in another component.
So I have created my own url/json to test the web application on itself, but as I said, it is possible to make the same thing but with a real http URI like it can be seen here: https://angular.io/docs/ts/latest/guide/server-communication.html#!#cors
They use:
let wikiUrl = 'http://en.wikipedia.org/w/api.php';
And I use, as of right now:
private datesUrl = 'src/example.json'; // URL to web API
#Injectable()
getDates(): Observable<Date[]> {
return this.http.get(this.datesUrl)
.map(this.extractData)
.catch(this.handleError);
}
So I believe my next step would be to change that datesUrl and write the http written above: http://localhost:8080/rest/getCars/20130505, so that it connects to Tomcat.
But my problem is that I don't know if this is going to work without any connection done between apache http server and tomcat. I've seen there are connectors, like mod_jk and mod_proxy http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypass
and so on. I would like to know if, in my case, if I need to use this modules for apache http server or it's not necessary, since I have never seen any of this and install the modules is proving to be a challenge. The end game objective I have is to go from local to a real server, but as far as I know there is no need for anyone from the outside to use the webpage, it's only for the business itself, so with access to the server/machine I could still access localhost, same as I do when I test it locally.
You don't need any special connection between the PHP server and the Tomcat server: it's a plain-old HTTP request. Tomcat doesn't care if your PHP script made that request, or if it came from the open internet.
In the case of the PHP script making the request, it's making its standard HTTP call, and doesn't care that you are running a Tomcat server locally or whatever. Just go ahead and do it. If Tomcat is already responding to HTTP requests on that URL, then calling it from PHP requires no further configuration.
I want to know which all modules in apache server supports wsman profile completly?
Have mod_wsman module for configuring openwsman web service in apache.
You can download source code from this link .https://github.com/Openwsman/mod_wsman
make , install and configure it in apache.
mod_wsman is openwsman-server but without the http stack.
It's an Apache plugin, so you can use the Apache http stack to handle
requests and pass them to the openwsman-server backend for processing.
mod_wsman is not very well maintained.
Assuming by wsman you mean WS-Management...
Of the standard modules that ship with Apache Web Server (httpd). None.
Apache Tomcat also has no support for this.
I want to add a javascript based chat system to my web app. I have read in many places that apache needs to forward(proxy) the requests to the xmpp chat server.
From what I have understood , I either need to add proxying support to apache server
OR use the jabberHTTPbind servelet.
I am trying the first thing. Add proxy support to apache. Now within Eclipse I am using Tomcat 7.0. I think this Tomcat comes with its own web server and is not using Apache. Is that true ?I am using Tomcat from http://tomcat.apache.org/download-70.cgi and added server in Eclipse by providing its extracted path.
I am not able to find any apache related folder structure eg(/etc/apache2/apache2.conf) within my Tomcat extracted directory.Also can't find httpd.conf anywhere .
Should I need to download apache separately and connect my tomcat to it.
I think adding proxy support to apache is required because javascript code won't be able to connect to any URL other than the current domain. so the question again is the same , where are all these apache2.conf and httpd.conf to add mod_proxy. and where can I do the virtual host mapping.
Any help to move ahead with be very much appreciated.
You need to install the Apache HTTPD server and enable reverse proxying. Read the doc on mod_proxy on how to do this. There are tons of resources on Stackoverflow as well; search for Apache reverse Proxy. The conf files you mention are part of the Apache HTTPD install.
javascript code won't be able to connect to any URL other than the current domain
That is generally true unless you enable CORS
I am playing around GeoServer and I have a Apache HTTP Server
I want to put GeoServer on my Apache HTTP Server, but we can only download a WAR file of GeoServer for Tomcat.
Is it possible to install Tomcat on Apache HTTP server?
Tomcat is seperate product which has nothing to do with the Apache Web Server and has to be installed separately,
Apache Tomcat has nothing to do with Apache HTTP Server. If you are trying to deploy some java webapps with JSPs and Servlets (and may be other web framework that uses these two) you just need to install tomcat server only. You can download it from here.
If you want to know the difference b/w Tomcat and HTTP server its given in this question
Hope this is useful. If any mistakes pardon me.
Recently our Software Analytic provider (NETTRACKER) sent us a plugin in order to be able to capture visitors in a better way. This plugin is for Apache 1.x and Apache 2.x. They said and I quote
that since Apache Tomcat is built on Apache HTTP server the configuration of the plugin should be the same.
I have looked for a httpd.conf in our tomcat deployment but we cannot find one, the only configuration that is similar to that one is the server.xml under the /conf directory.
If someone has better information regarding these two incredible products (Apache HTTP server and Apache Tomcat) I will greatly appreciate to draw the differences.
EDIT:
In case you are curious we know that Apache Web Server and Tomcat can work together using the mod_jk option and other proxys. But this will be too complex for our deployment.
Apache Tomcat and Apache HTTP are completely different server technologies. It is impossible to use a plugin for Apache HTTP server with Tomcat.
Apache HTTP server is developed in C and so are the plug-ins. On the contrary Tomcat is now completely developed in Java. Tomcat doesn't only serve static content, but it can also serve JSP pages and servlets.
Tomcat is used for hosting Java Web Applications. It can sure serve static content - you can host a web application using only Tomcat. Secure connections are supported and the performance is also very good (comparable with the performance of HTTP server).
A plain installation of Apache serves static content. Using the appropriate plug-ins, HTTP requests can be redirected to an application server (Tomcat, JBoss, Glassfish) or a script language interpreter (PHP). With this way dynamic content can be generated. The big advantages of Apache are the numerous plug-ins available, which allows administrators to configure and monitor web sites any way they want and that is the most widespread server available. This makes it the most secure solution, since it is thoroughly tested and any discovered flaw is corrected very quickly.
The best solution would be to use Tomcat proxied by an Apache server. It isn't so difficult to set up. If you can't do this, then you can't take advantage of Apache's plug-ins.
You see this confusion all the time. Many people think that Apache is a web server where in reality it is the name of an organization that has a web server project called "The Apache HTTP Server Project". In short the web server is called HTTPD (D as in daemon or Unix process).
Tomcat is another Apache project. This project implements a Java servlet engine to serve JSP pages and servlets. Tomcat and HTTPD have nothing to do with each other. However, you can set up HTTPD and Tomcat so that they work together. This way you can have HTTPD serve all static content, do URL rewriting and much more fancy stuff that the built in Tomcat web server can't do (or can't do very well). Whenever a JSP page is requested, HTTPD will pass the request on to Tomcat. Tomcat will process the request and will hand the output back to HTTPD which in turn will send it to the client.
Apache has many interesting projects. E.g. there is also a project called Geronimo which is a Java Enterprise server (J2EE). You can e.g. choose to embed Tomcat inside Geronimo to handle requests for JSP's and servlets where Geronimo does the more enterprisy stuff (LDAP, Messaging etc.). And you guessed it probably already, you can use HTTPD as a static content server for Geronimo as well.
totally bogus. Apache httpd plugins are written in C, Tomcat is pure Java.
Tomcat is a Java servlet engine. It can be hosted under Apache or IIS or quite a number of other external facing web servers. It sounds like you may be currently running your Tomcat instance standalone...
If you serve the JSP/servlets off of port 8080 and have it do things standalone, on the same host machine that Apache is running on, this can allow you to have them loosely coupled. Having multiple web servers fielding independent requests is not recommended, especially if you want to use server-based authentication along with Apache. Typically, you have one outside facing server that shepherds everything through it... Apache does this quite well, and the plugin you mention probably relies on this type of setup (everything gets wired through Apache) for its features/capabilities, based on your brief description of it.
If you would like to serve up your Tomcat servlets under Apache, you could configure apache to forward a class of URIs to your tomcat server instances. you could achieve this type of forwarding through mod_rewrite. this is a slower option performance-wise, as it adds slight overhead on everything you server up. You could also proxy incoming requests via a CGI mechanism similarly, from Apache to Tomcat.
mod_jk will simplify deployment and increase performance for placing Tomcat into an Apache server config. It is pretty painless to configure if you follow the docs, so I am not sure what you mean by "too complex" for your deployment -- if you want Apache and have Tomcat already, it would seem only a matter of slight config changes to get mod_jk downloaded and installed.
