RE: [JBoss-dev] Re: [JBoss-user] JBoss in a multi developers environment
Hello Mike, If I understand your question correctly, yes (well, no to the 'dreaming' question :-) ). The 'default' list of ports would either be in the config file (like example below), or in each of the services' respective config files. I think this is what you mean (?). At config-time, just specify the server (default, serverA, etc) you want to run, in servicebinding-service.xml. Sacha - let me know if this is NOT what you mean! Well, not exactly. In fact, I should simply read more carefuly your doc. I was thinking to something like that: server name=default service name=jboss:service=Naming listen-host-name/listen-host-name listen-port1099/listen-port /service service name=jboss:service=Hypersonic listen-host-name/listen-host-name listen-port1476/listen-port /service ... /server server name=serverA default-host-nameserverA_hostname/default-host-name !-- no service tag necessary... implicit extend statement -- /server or something like server name=default service name=jboss:service=Naming listen-host-name/listen-host-name listen-port1099/listen-port /service service name=jboss:service=Hypersonic listen-host-name/listen-host-name listen-port1476/listen-port /service ... /server server name=serverA extends=default default-host-nameserverA_hostname/default-host-name !-- no service tag necessary -- /server but the default-host-name could be in the server tag as: server name=serverA extends=default default-host-name=serverA_hostname/ It is just that on multi-homed computer, the port is generally the same, only the IP changes.

Re: [JBoss-dev] Re: [JBoss-user] JBoss in a multi developers environment
Hi all, I've been posting about this subject a while ago, and we are using multi instances of jboss/eclipse and tomcat in the same machine for use by developers remotely. We use the approache of a multi-homed host, with more then one ip address. At first we some of services out, changed the conf/jboss-services.xml including bind-address tags. In one instance , we changed jboss-service.xml inside jmx-html-adaptor.sar to use other port. Is there a way to change the bind address instead???

RE: [JBoss-dev] Re: [JBoss-user] JBoss in a multi developers environment
Emerson, The JMX-HTML Adaptor MBean (from Sun jmxtools.jar) does not allow the specification of a bind address - only a port, and max # of clients. There is no attribute for it, and in fact, the server socket open call uses the no-address constructor (port,backlog). That said, I thought someone was working on a JMX-HTML replacement, but I don't know where it stands. It would be pretty simple to write a new one, say org.jboss.jmx.adaptor.html, that is like Sun's but takes an address attribute and uses it. #mike -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Emerson Cargnin - MSA Sent: Monday, June 24, 2002 9:55 AM To: [EMAIL PROTECTED] Subject: Re: [JBoss-dev] Re: [JBoss-user] JBoss in a multi developers environment Hi all, I've been posting about this subject a while ago, and we are using multi instances of jboss/eclipse and tomcat in the same machine for use by developers remotely.

So you can undeploy jmx-html-adaptor.sar, and instead deploy this servlet to your Jetty/Tomcat. Neat. The bigger benefit here is that you can put your own security constraints on it so Joe Fatfinger can't point a browser at 8082 and stop or remove running services. I like.

I've been thinking about ports and other configuration issues. This goes back to the mega-thread about whether configurations should all be stored together, or not. Scott has hinted at a future omniscient/persistant JMX-based configuration mechanism. It seems to me that all these problems could be solved by taking different JMX Agent 'views' across all the services. For ports you simply have a PortView page, which is configured to list all the ports. No doubt you will also need a files/directories/urls view and several others. These views could be configured in xml and would be far more flexible than hard-wiring a service for each view. Furthermore they would not require any further integration work on the part of the service. Users could configure their own views. You could have novice/expert views etc Finally any JMX based approach to this would integrate straight into whatever Scott has planned, whereas a BindingService will be yet another service to configure. Comments ? Jules P.S. I guess we just need a JMX view servlet which has access to a number of configuration files (.jxml?). When you hit one, it just renders the JMX view... - simple !!

RE: [JBoss-dev] Re: [JBoss-user] JBoss in a multi developers environment
Guys, I've been thinking about this. Wouldn't it be better/easier to create a UI configuration tool than do this port mapper stuff? What I mean is a JBoss configuration tool that for each component asks you what port you want your JNDI server to run on, Web server, etc... as well as other config information. This tool could be smart enough to determine if something is already running under a certain port and tell you so you have to decide the new port to run under. This stuff would not only be usefull for a multiple developer environment, but would be extremely useful in an Installer and management GUI, and IMHO, would be more reep more significant benefits for the JBoss project. IMHO, what you're proposing would just create ugliness and complication in the code base. But maybe I'm wrong here. I don't know. Do whatever you want.

Re: [JBoss-dev] Re: [JBoss-user] JBoss in a multi developers environment
Not exactly, Bill. By default the mapping should just return the default mapping requested by the system. If and only if the user wants to run multiple copies of JBoss on a single machine, do they add a configuration mapping to the mapper. I should be no more complex then what we currently have with the ability to centrally mange ports. This is the best of both worlds if you ask me. Anyway, GUIs need to run on top of JMX (configuration files), because not all hardware has a graphical display. -dain Bill Burke wrote: All I'm saying is that this is just another configuration file in an already complicated system.

RE: [JBoss-dev] Re: [JBoss-user] JBoss in a multi developers environment
I had been working on an alternative solution to this problem (see earlier thread in Mid-April: Multiple Instances). After some thought and work, this (Dain's) seems more robust (at least to me). The other way was effectively a proxy server sitting on a single (known) port, directing streams to the correct endpoints. The problem is that not every wire protocol puts enough (or anything) in the initial packets in the stream to identify the service - so I don't think the proxy would work as we discussed before (HTTP would work OK, but it looks like JNDI and RMI wouldn't). Unfortunately, I didn't do any packet sniffing to find this until I had already written the proxy server/MBean :-(. Q 1) I assume service name would be the JBoss service name? (jmx-html, webserver, etc). IP service name would be insufficient as there are multiple services serving HTTP (webserver, jmx-html, jetty/tomcat). 2) How do clients find what port to which they connect today? For example, w/ a separate-VM-client that does a bean lookup (via configured port - eg 1099) - where does it find the RMI port number(eg ) to make the method call? Is it in the object returned from the JNDI server? (Probably a dumb one, but not obvious to me). #mike -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Dain Sundstrom Sent: Monday, May 20, 2002 2:44 PM To: [EMAIL PROTECTED] Subject: Re: [JBoss-dev] Re: [JBoss-user] JBoss in a multi developers environment Jules Gosnell wrote: OK - that's not so bad.

I still think you need lookup - so that an external service can find out which port to talk to. This becomes even more important when you are allocating these dynamically. You have become the registry and thus ultimate authority on what service is serving on what port. Jules P.S. If a service explicitly requests it's allocation then, for the sake of symmetry, it should explicitly request it's deallocation. Yes, you could assume that when the service that owns a port quits you can garbage collect the port - but what if the service lives on but no longer requires the port ? Garbage collection should be a safety net - not the primary mechanism. -dain ___ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development ___ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development

Cool.
I suggest you start by coding the simplest thing possible; like just
give ports in serial order in a range (like DHCP does), as a proof of
concept. You can make it much more interesting later. This will allow
the people who write the other services to add calls to your interface.
Good luck and KISS

(jmx-html, webserver, etc). IP service name would be insufficient as there are multiple services serving HTTP (webserver, jmx-html, jetty/tomcat). It is the full JMX ObjectName string of the service. Since this is not likely going to change for each instance we need an instance name to differentiate requests for the same service in the event that you want to always assign the starksm instance of tomcat port 8080. This could be an attribute of the port mapping service in the instance. Q 2) How do clients find what port to which they connect today? For example, w/ a separate-VM-client that does a bean lookup (via configured port - eg 1099) - where does it find the RMI port number(eg ) to make the method call? Is it in the object returned from the JNDI server? (Probably a dumb one, but not obvious to me). RMI ports are hidden in the JNDI object bindings. The JNDI url used by the client to obtain the InitialContext determines all RMI ports transparently. The same is not the case for http so in general this is a detail that is outside of the scope of the mapping service in my opinion. Another layer has to pick up this detail.

Yes, this is what I am talking about in terms of the server identity being presented as part of the request to allow the starksm config to always bind the http service on 8080 so I can use the default config. Dain has to go and change his config in order for him to talk to his dsundstrom config instance.

Ya, duh. Is hostName also mappable? If so, I think this interface would
be better:
void allocateServicePort(String serviceName, ServicePort servicePort);
void deallocateServicePort(String serviceName, ServicePort servicePort);
ServicePort contains a hostName, port, and InetAddress. I don't like
the name ServicePort, but you get the idea. Allocate can change the
information, but reserves that slot until deallocate is called.
What do you think? This is outside of my area, so I could be easily way
off base.

Sure. Then we have the following signature:

int defaultPort, InetAddress defaultAddress);

What is this? Can you give an example? Its what I have been referring to as the starksm and dsundstrom config instances. Say we setup two JBoss instances of main.jboss.org. As Dan is saying, I don't want to have to change my configuration to connect to my instance each time the server is restarted. So when Jason configures my instance he adds: mbean code=...ServiceBindingMgr name=...,service=ServiceBindingMgr ... ServerNamestarksm/ServerName /mbean while for your instance he adds: mbean code=...ServiceBindingMgr name=...,service=ServiceBindingMgr ... ServerNamedsundstrom/ServerName /mbean Now there can be a static configuration for our instances for which the client ports, address in use is invariant across instance restarts. // The default port int port; // The default interface InetAddress bindAddr; Of these values, would the ServiceBindingManager only be allowed to change virtualHost, port, and bindAddr? Yes. BTW, do you actually like this idea Scott? Yes, its a definite improvement over what we have. In the future I would like to see this integrated with a client side naming service but as I said that is another layer. ___ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development

And how does it autogenerate the URLs I enter into my browser, the config file for my firewall to allow the RMI ports through, the config file for my proxy server, etc. Allowing for static bindings does not preclude the possibility of dynamic bindings, but we need to start there and support it.

Mike,
I talked with Jason and he said the best module for this code would be
jboss/server and a package of org.jboss.service.portmap. I think
servicebinding would be a better package.
Anyway, post a patch when you get a simple mapper working.

Ok, but such a request is not going to come from the service. Rather there might need to be multiple bindAddress values in the ServiceBinding returned by the mapper.
