Tomcat and JBoss

Hello! I'm not that new to web programming in Java but there are some things that I think I need to fully understand. Can anyone here give me a comparison between Tomcat and JBoss? What are the similarities and key differences between the two? Tomcat is a servlet container while JBoss is an application container(?? not sure about that, still haven't read enough about it).
Thanks in advance,
Romaine

Hi Romaine,
Tomcat is not only a servelet container...its actually the webserver which is a servlet container and jsp engine as well.
Where as JBOSS is one of the application servers where it provides the run time environment for the business components( the ejbs) in addition to the support environment for servlets and jsps.
examples of application servers: JBOSS, WEBLOGIC, WEBSPHERE

Distinguishing between Tomcat and JBoss

I have a servlet that does a JNDI lookup, and I need that servlet to be able to figure out whether it's being served by Tomcat or JBoss (because the JNDI lookup is done differently depending on which servlet container it is). Using getServletContext().getServerInfo() doesn't help because it returns tomcat in both cases, since JBoss uses Tomcat as the servlet container. Does anyone know another way of determining whether it's Tomcat or JBoss?
Thanks!

How to compile jsp project on the plateform of Myeclipse and jboss
hi :-) this is not eclipse forum and not that sure about your problem but i'll try to answer :-)
i'm not sure how you create your war but there something wrong with your web.xml. kindly check it :-)
by d way, you can deploy your project in my-eclipse by
- right click on the project then select my-eclipse > Add and Remove Project Deployment's
- a new window will open and you can now configure how you deploy your project :-)
other alternative edit your jboss-service.xml then put something like this
<attribute name="URLs">deploy/, file:/D:/workspace/deploy</attribute>
(note, change the path according to your needs)
regards,

What are the steps to Migrate a Web Service from Tomcat to JBoss

Hi,
I am totally new to JBoss and need some help. I mostly worked on BEA and Oracle. I have a web service deployed on Tomcat that needs to be now migrated to JBoss. What are the steps in moving a web service from Tomcat to JBoss.
Is there some step by step tutorial on developing and deploying a web service on JBoss along with sample build script.
Any help is really appreciated.
Thanks

R u using axis. If you want to stick with axis and don't want to use JBossWS there is nothing else you need to do. Move all the axis to Jboss. If you plan to reimplement all ur services in JBossWS here it is:

http://jbws.dyndns.org/mediawiki/index.php?title=User_Guide
Let me know if you need anything else.

Tomcat and EJB will work?

Author: kirankumar_j Feb 6, 2004 9:19 AM
Please let me know whether we can write EJBs in Tomcat and execute in the project?
I am new to EJBs.
Kiran

Hi Kiran,
Tomcat alone is just a Web Server as mentioned in the previous post.
Go for App Servers like Jboss-Tomcat, Weblogic or Websphere.

Coherence and JBoss

Hi,
I've been looking for documentation on setting up Coherence as a JBoss service and the only thing I could find in these forums was meant for JBoss 3.2 and Coherence 2.3.1 (see the FAQ titled: How do I test the Transactional Cache?).
Obviously this does not work with JBoss 4.0 and Coherence 3.1.
Is there an updated answer for this question?
Thanks,
Glenn.

Glen,
Coherence is pure Java and does not rely on any JBoss-specific classes or functionality (with a few exceptions listed below), so it has worked fine with every version of JBoss we've ever tested and our customers have ever used.
The areas in which there could be minor conflicts are those areas where Coherence does plug in more tightly with container functionality; for example:
1) Session management: Jboss ships with Tomcat (and there used to be a Jetty option), and Coherence*Web supports Tomcat (and Jetty)
2) JTA transactions via the J2CA adapter (coherence.rar): the note you pointed to
3) Hibernate: Coherence has a brand new provider (in 3.1) for Hibernate, and Hibernate is now a part of Jboss.
As far as I know, there are no known problems with any of the above three items (or others) on Jboss, and if you do encounter any apparent difficulties, just let us know.
Peace,

Upgrade the default Tomcat and Apache

Hi
Is there a working and correct way to upgrade and run a Tomcat and Apache server of your pick instead of the pre installed versions in OSX 10.4.8 server.
Meaning that i want to start and admin them throught Server Admin interface, and making Jboss notice the new Tomcat aswell.
Mikael

If you're asking here, the answer is probably no.
It is possible to build and install later versions of all the Mac OS X Server-bundled apps, including Apache, Tomcat, postfix, bind, etc., etc., but in most cases once you do you lose the ability to drive them via Server Admin.
Server Admin knows what it knows - more importantly it doesn't know any of the features of later versions of the apps (it may work with point released (e.g. Apache 1.3.20 -> 1.3.30, but it won't work with major versions like 1.3 -> 2.0).
So if you go that way you're on your own as far as configuring and maintaining the service is concerned.
Leopard (10.5) will include later versions of these apps if you're prepared to wait.

Tomcat client + JBOSS server

Regarding to JBossIDE-Tutorial.pdf I worked through this tutorial and I reached my first EJB
Now I�m trying to deploy the application as clent and server using Tomcat 5.5 and JBOSS 4.2.0GA ( on two different host placed in the same lan )
I have the same project on the JBOSS and the new one in Tomcat
In Tomcat I copied only the interfaces and servlet because I want to call the EJB method from Tomcat application container
I modified the code of ComputeServlet.java in this way
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingCotextFactory");
env.put(Context.PROVIDER_URL, "jnp://192.168.0.13:1099");
Context context = new InitialContext(env);
Object ref = context.lookup("ejb/Fibo");
home = (FiboHome) PortableRemoteObject.narrow(ref, FiboHome.class);during the lookup method I reach the same error message
--------javax.naming.CommunicationException: Could not obtain connection to any of these urls: 192.168.0.13:1099 and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server 192.168.0.13:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server 192.168.0.13:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]]
it seams that the Tomcat client doesn�t reach the JBOSS server
I wonder if anyone could give me any suggestion
Many many thanks

ok many thanks
now all work properly
the real problem was the ip address of JBOSS Server
I found interesting faq at this link
-> http://wiki.jboss.org/wiki/Wiki.jsp?page=JBoss42FAQ
Frequently Asked Questions about the JBoss4.2 Release
1. . Why can't I connect to the server remotely? All the services appear to be bound to localhost only.
* That's correct before 4.2.0.GA jboss always bound to the any address "0.0.0.0". You wouldn't believe how many people would put unprotected instances of JBoss on the internet, or even on their own local LAN. Now you have to explicitly choose to do that, so it takes some thinking about before you revert to the old default behaviour with the "-b' option of jboss. e.g.
./run.sh -b 0.0.0.0
For Windows, use
run.bat -b 0.0.0.0

Question about blazeds turnkey, tomcat and directory structure

hi. this question is pretty basic...been reading sujit reddy g's blog on installing/setting up blazeds.
in one article he creates a samplewebapps directory in C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\samplewebapps and copies the blazeds WEB-INF/lib into that directory and the configuration files in the flex folder across as well...http://sujitreddyg.wordpress.com/2009/04/07/setting-up-blazeds/
in another article on invoking java methods from flex he configures the remote-config.xml file directly in the blazeds\WEB-INF\flex folder....http://sujitreddyg.wordpress.com/2008/01/14/invoking-java-methods-from-adobe-fle x/
wasn't sure why in the first example he copied the files and folders to the samplewebapps directory while in the second example he just configured the files within the blazeds directory...thanx...(i'm a newbie at server side development)

I'll take a stab at it. The key thing to realize is the BlazeDS code is ADDED on
to the appserver. E.g. for Tomcat/WebLogic/et al one adds the reference in the web.xml file in WEB-INF.
So, what is that add-on?
1. Executable files. These are jar files and typically stuck into WEB-INF/lib
2. Configuration files. flex/services-config.xml is specified in web.xml. It refers to the other config files in WEB-INF/flex
So, the config in web.xml tells Tomcat (and its forked commercial products) to load up the Flex jars and run some classes. By standard, the "run some classes" follows the servlet lifecycle and runs specific methods in the class when the servlet is loaded, called, destroyed. So, Flex jars have a class which implements the servlet interface.
Incidentally, you may also see references to log4j, Spring, and other frameworks in the web.xml as well. They do the same sort of stuff. So, Tomcat does the passing of the HTTP packets and stages them into Java classes and the hooked in frameworks do add their own behaviours to the setup.
HTH,
TimJowers
P.S> Also note in Flex when you setup the project properties for a Flex Project then you need to match up your URL and "context" to what you have on your server. In his exampe, the "samples" context may have already been setup so easier to use. What is a "context"? The idea is to have more than one webapp running on an appserver. In Tomcat, its basically just the subdirectory under "webapps". That directory name becomes part of the URL. E.g. webapps/samples -> http://localhost:8080/samples or webapps/mytest -> http://localhost:8080/mytest

Errors when using tomcat and netbeans combo.[Solved]

Hi I'm trying to set up a netbeans/tomcat7 development environment for servlet development.
I have tried this on 2 machines without any success.
The steps I have followed are as follows.
First I installed tomcat7 and netbeans from using pacman, then to be able to configure tomcat from netbeans I made the config files write permission 777, as it's just a development server security is not an issue.
From there I started up netbeans started a new project and set the server to tomcat and pointed the Catalina home dir to /usr/share/tomcat7.
When I try to run the example jsp project I get the following error:
description The server encountered an internal error () that prevented it from fulfilling this request.

From the error, it appears that there is no JDK installed - only a JRE, could that be the case? If you do have a JDK installed, then Tomcat is not finding it.
I would also not run this on the openJDK, in case you are doing that. I would use the proprietary Oracle/Sun JDK. It's in the AUR, or simply download it from Oracle.
I was not even aware that netbeans and tomcat are available from pacman. I always "install" those myself manually (i.e. unpack them into a folder). They are simply Java apps that can be installed anywhere, as long as you point them to a valid JDK.

Configuring tomcat and apache on the same system

i need to configure tomcat and apache on the same system.
first i have configured apache and it is working well.
Next is have configured tomcat and it is working well.
i need to interlink tomcat and apache. so i downloaded jk connector and i have configured it.
i gave an entry in the httpd.conf as
Include /tomcat/conf/auto/mod_jk.conf
i have copied the file mod_jk.so to /usr/local/apache/libexec/
went i start apache after the entry is given it gives the error like this
cannot load /usr/local/apache/libexec/mod_jk.so into server: ld_so.1. /usr/local/apache/bin/httpd: fatal : libgcc_s.so.1 : openfailed : no such file or directory in linux
please help to configure this.
i have done every thing as it is in apache.org documentation. please give the complete configuration. some say that tomcat is not compiled according to apache1.3. but i configure jk connector as --with-apxs=/usr/local/apache/bin/apxs
send me the reply
thankqs in advance

Hi,
I'm working in a linux machine and choose to use also two different users. Of course I'm using two different ORACLE_HOME directories.I think that the best approach.Just a question ,are you keeping the "GROUP" same or different?

Load Balancing, Tomcat, and SharePoint

I'm a new BusinessObjects customer and am working on getting all of the hardware in place for a new install. The initial plan is to have two BOE servers, and two tomcat virtual servers, with a hardware based load balancer (F5 BIG-IP Switch: Local Traffic Manager 1600 4GB, possibly) in front of the tomcat servers to handle the load balancing.
But, I'm starting to think that it would be a good idea for us to integrate directly in to our SharePoint portal using the SAP SharePoint Integration option.
So, here's my question. If we do that, then our users will get to their BusinessObjects information via SharePoint. So, SharePoint and IIS will be the web server. Will we still have a need for the Tomcat servers? Will SharePoint point to the load balancer, then to Tomcat, and finally to the BOE server, or will it go right to the BOE server, thus negating the need for the tomcat servers altogether, and also even negating the need for the load balancer? If so, can the BOE app servers themselves still be load balanced?
Hopefully this all makes sense - like I said, we're a new customer, so I don't fully understand all of what the servers are doing. I've spent several days searching the forums & the web & reading documentation and haven't come up with an answer yet, so I'm reaching out to you all & hoping somebody can clear it up for me. Thanks!!

Thank you for your input, Denis, this does help explain things. Also, thanks for pointing me to that Windows Patterns document. I hadn't seen that one - since we're starting out on 4.0, I've only been looking at documents under the 4.0 folders...
It sounds like we may want to utilize this same load balancer to balance the SharePoint traffic as well, while we're at it. Right now our SharePoint server is clustered using Microsoft Clustering, but not load balanced in any way. Or maybe we just post a link from within SharePoint to the regular old BI LaunchPad and call it a day!
So, if I understand correctly, if we utilize SharePoint, any traffic/processing that the Tomcat server would have handled would now be handled by the SharePoint server, which could potentially be significant. The actual processing of the reports, though, will still get handled by the BOE Cluster, which takes care of its own load balancing, so we'll be fine. Really the only thing the hardware load balancer does is allow the presentation layer to be load balanced - the layers beyond that get load balanced automatically via CMS. Is that all somewhat valid? In the patterns doc, there's Application Servers separate from the BOE Servers. We were just going to have two BOE servers and two Web servers. Where do the application servers fall in, and are they load balanced using the hardware piece?
If we were just concerned about High Availability, it seems like maybe we could more easily use Windows Clustering on those Tomcat servers, and avoid the hardware component altogether. Do the Web servers really get hammered that hard that we need them load balanced? It seems like the BOE servers are the ones doing the heavy resource intensive tasks and we get them load balanced without the hardware anyway, so maybe load balancing the web servers is overkill..... I'm sure a lot of this is tough to answer, I'm just trying to get a feel for it. I want us to have our best performance & be somewhat future-proofed, but don't want to buy things that I don't need to! We're probably looking at a small, 10-20 concurrent user setup for starters, and out to say 200 concurrent max once it's fully rolled out...
Thanks again!!
