RE: [HiveMind] Extension to adder example
Right on the money ... except that I probably would not both defining the service
model for Adder
and Subtractor; the default (deferred) is less efficient, but less trouble as well.
Making those
services singletons (rather than deferred singletons) is a premature optimization.

What I'd like to do is to define a service analogous to the Adder,

Then, I'd like to define a service, Math that uses the Adder and

public void setAdder(Adder adder) {

}
public int subtract(int arg0, int arg1) {

and call it from code thus (after appropriate registry construction,
etc.):
Math math = (Math)
registry.getService(hivemind.examples.Math,
Math.class);
System.out.println(Result of add: + math.add(arg0, arg1));
System.out.println(Result of subtract: +
math.subtract(arg0,

I'm a bit confused as to how to tie all of this together. Could
someone provide some pointers?
Thanks.

RE: [HIVEMIND] Examples Please?
We're working on the docs and are setup now to provide more and better examples. HiveMind is very, very new. If it looks polished, that's a compliment ... and reflects that many of the ideas in HiveMind gestated inside Tapestry over the last couple of years. I'm using HiveMind at work ... I think of it largely as a refactoring tool. Case study #1 is based on one usage of HiveMind. However, its a proprietary application and completely huge. A module maps to a jar; you'll have multple packages in the jar but only a single HiveMind module. If that's a problem, one solution is to refactor your code into more small modules. HiveMind really supports this well, since it (effectively) adds a late binding, where module A defines the interface, and module B supplies the implementation. Due to our current build process, we have a similar issue: multiple logical modules that are packaged together as a single JAR. In an ideal world, there would be a ClassLoader.getTResourceInFolder(/META-INF/hivemind) ... but there isn't. Instead, we have external descriptors, a directory under WebLogic where we store the extra class loaders; our servlet's registry bootstrap code processes all the XML files there as well as those found normally. It works well, but is not quite ideal for a clustered EAR deployment; we'll want to graft something together for that soon. Possibly, our build system will write a catalog of these external descriptors into a central file. -- Howard M.

RE: [HiveMind] Extension to adder example
Could you share with me how to build the Adder.jar and Subtracter.jar (if indeed there is any difference between the current example), and then how to use them? If all I have to do is build the jars, and put them in the classpath, then follow your example, very cool, I'm 100% of the way there! Thanks Harish. Yep, that's the whole point ... build the two jars and you have Adder and Subtractor ready to go. HiveMind will locate and parse all the hivemodule.xml's into one consistent registry. If you get hivemind.examples.Adder it will combine the interface from the first jar with the implementaion contributed by the second jar. So ... obviously I've been failing on getting the message out about what HiveMind does if this is coming as a surprise now. -- Howard M.

Re: [HiveMind] Extension to adder example
I would agree with Bill here that there is only so much words can convey. I had the same problem until the bootstrapping example was published, that's when everything clicked in place. I always like the illustration kind of documents (and hence my Illustrating Tapestry!) which is always concrete and leaves little room for ambiguity. As far as the names go, I am still with service and service-point. An interface would tend to imply that this is the definition of the interface which it is not and the same applies to implementation. -Harish Bill Lear wrote: On Wednesday, September 17, 2003 at 10:08:14 (-0400) Howard M.

Re: [HiveMind] Registry
Ole Arndt wrote: Hello infant HiveMind community, first a short self-introduction: I am a developer from Germany. For my pet project, a mud like simulation, inhabited by (more or less) intelligent agents, I was looking for a framework to use. I knew Avalon from my job and had heard of pico- and swing container. When I discovered HiveMind I was equally impressed by the underlying concepts, the amount of documentation and the clean code. Until now I haven't build anything with HiveMind but I have compiled it, ran the tests and did some source code reading. I lurked on the devel list (via gmane) for a few days to learn about the people and the current status of the project. But now it's time to step forward with a few questions/remarks. Here we go: The HiveMind registry is currently static, right? Once constructed it can't be changed. This is correct. Due to the potentially very long run times of my simulation I want to be able to add/remove modules/services on the fly at any time. If get it right, this is currently only possible by building an new registry. Correct? What I want to have in the end is some kind of new service notification mechanism like in the beancontext API, or with a Jini lookup service. This does not need to be build into HiveMind, but is probably only possible/easier with some support from the lower level. Any plans in this direction or is this out-of-scope for HiveMind? I think that will depend on the needs of the community, but Howard is the best person to answer that. An easy improvement in this direction would be if the RegistryBuilder took an old Registry to build upon as a parameter. This would probably imply that the registry keeps its XML configuration. Regarding the XML configuration: I agree that the current naming really isn't very intuitive. I think the best proposal until now is the one Harish made: service -- service-point extend-service -- service extension-point -- configuration-point extension -- configuration There you go..!! Though, if some native English speaker found a more descriptive word for `point', like `definition' but not as long, it would be even better :-) Another issue: There isn't much visual difference between the following two lines and that makes it hard to read: extension-point id= / extension point-id= / What speaks against calling the id attribute `id' in both cases? I actually like this as it is more intuitive even if it is visually confusing initially. You soon get used to it!

[HiveMind] TSS
A couple of ideas I may be pursuing at work ... Creating interceptors to enforce transaction boundaries. Creating intreceptors to enforce declarative security. Creating interceptors that record invocations counts as JMX beans. HiveMind's take on the DAO factory: Define a DAO interface and supply several implementations (for different databases or environments) in a configuration point. Have a service factory create a service implementation that delegates to a particular implementation, i.e. client code -- wrapper service -- actual service The wrapper service is created at runtime. Client code only sees the wrapper service, never has to even know that a dynamic selection takes place. Wrapper service is constructed at runtime using a service impl factory ... look at how EJBFactory is implemented to understand this. Service that creates C#-style delegates for use in Swing apps. You feed in: object, name of public method (of object), listener interface type ... it spits out delegate object that implements the interface and invokes the public method (possibly, passing the event in). Optional: if listener interface defines multiple methods, you decide which to connect. -- Howard M.

I think an xdoclet module for HiveMind would be WONDERFUL! That way, you could describe services, extension-points, interceptors, etc. in the JavaDoc comments of your class and have your module descriptor file generated for you automagically!

Re: [HiveMind] TSS
I think the first idea is PERFECT. I came up with the idea for my framework by using JDO in a web application (no transactional support involved). So, I used invocation decorators or, in HiveMind, interceptors to begin the transaction if one didn't exist already (and commit it upon successful completion of the method). I think that might be a great idea for an example. I also like the DAO idea. I wrote an article about a new-and-improved DAO framework (http://www.javaworld.com/javaworld/jw-03-2002/jw-0301-dao.html) and I wish I had HiveMind around for that! - Original Message - From: Howard M.

[hivemind] Design comparison
I have been monitoring hivemind as it is similar to a framework I helped design for work (not OSS). What interests me is the way that different groups in Java-land are moving towards the small POJO approach, and away from dreaded EJBs. I just want to sketch out some features of the framework I use in case it gives you some ideas. Similar to hivemind: Aims to enable a system to be written as a large number of small services. Each service can call other service in flexible ways. Each service is defined by an interface. The interface must have only _one_method. Each implementation must have no instance variables (singleton). Differences: - 1) The first parameter of each interface method must be a Context object giving access to configuration and connections. Is this IoC? 2) The selection of which implementation to use is performed late. The selection is based on - data in the method arguments - the services in the stack calling this one - the configuration lookupGroup interface=blah.TheInterface lookup caller caller=blah.SomeCallerImplementation / process process=blah.ImplIfCallerInStack / lookup/ lookup dataSourceType=Database process process=blah.ImplIfParamsWantDB / lookup/ lookup dataSourceType=File process process=blah.ImplIfParamsWantFile / lookup/ lookupGroup/ I include this to give some idea of what is going on. The process elements are the implementations, and which is returned will depend on the current state of the system and the method parameters. It acts like a big if statement. The lookup is hidden from callers by a class that simply has all the interfaces as methods, performs the lookup and then calls the implementation. 3) We have the concept of interceptors, again bytecode generated. We use them to open and close connections. Thus there is a doPre() method that opens the connection and attaches it to the Context, and a doFinally(), that is called as a finally block, that closes the connection. This obviously simplifies the service itself, and separates system logic from application logic. It is very powerful, and could be worth thinking about for hivemind. (our limitation is that each service can only talk to one datasource). 4) All our configuration is in XML resource bundles. This allows locale based config for the core server behaviour which we can control on a per session basis (although we haven't needed to yet). We chose to separate configuration from the services themselves, different to hivemind. The system we use allows single Strings, Lists, Maps and raw XML to be loaded from the resources by the program. There is no auto-bean conversion though which is nice in hivemind (although it only takes one line in our code). So, similar ideas in places but different in others :-) Stephen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [HIVEMIND] Examples Please?
Yeap it does ... As i said, just a first go at it, but if you point it to a bunch of classes, it will attempt to extract the services and extensions contained in them and bundle that into a module dd ... It needs a lot of work - no validation to ensure you are extending a already defined service is done yet for example ...

RE: [hivemind] Design comparison
I have been monitoring hivemind as it is similar to a framework I helped design for work (not OSS). What interests me is the way that different groups in Java-land are moving towards the small POJO approach, and away from dreaded EJBs. I just want to sketch out some features of the framework I use in case it gives you some ideas. I read a great article that, boiled down, said that Enterprise JavaBeans should be called Transactional JavaBeans because that's all you really get. Bloat, complexity and (due to dependencies on the app server runtime environment) limited testablility is the problem. All these POJOs (Picocontainer, swing, HiveMind, Avalon) are the reaction. Lots of HiveMind percolated and gestated in Tapestry. Similar to hivemind: Aims to enable a system to be written as a large number of small services. Each service can call other service in flexible ways. Each service is defined by an interface. The interface must have only _one_method. Each implementation must have no instance variables (singleton). HiveMind services may have any number of methods. They don't have to be singletons, though singletons are generally sufficient; the threaded service model allows one-instance-per-thread (but mandates that you tell HiveMind when the instances may be discarded). More service models on the way. Differences: - 1) The first parameter of each interface method must be a Context object giving access to configuration and connections. Is this IoC? I would say not; that's configuration information that should be provided by the container. 2) The selection of which implementation to use is performed late. The selection is based on - data in the method arguments - the services in the stack calling this one - the configuration lookupGroup interface=blah.TheInterface lookup caller caller=blah.SomeCallerImplementation / process process=blah.ImplIfCallerInStack / lookup/ lookup dataSourceType=Database process process=blah.ImplIfParamsWantDB / lookup/ lookup dataSourceType=File process process=blah.ImplIfParamsWantFile / lookup/ lookupGroup/ I include this to give some idea of what is going on. The process elements are the implementations, and which is returned will depend on the current state of the system and the method parameters. It acts like a big if statement. Those almost look like AOP method introductions; this doesn't have a parallel in HiveMind per se. The lookup is hidden from callers by a class that simply has all the interfaces as methods, performs the lookup and then calls the implementation. I'm not following this; in HiveMind services are represented by interfaces; the implementation of the interface may be a fabricated proxy or interceptor, or a user-supplied core implementation (or a fabricated core implementation). 3) We have the concept of interceptors, again bytecode generated. We use them to open and close connections. Thus there is a doPre() method that opens the connection and attaches it to the Context, and a doFinally(), that is called as a finally block, that closes the connection. This obviously simplifies the service itself, and separates system logic from application logic. It is very powerful, and could be worth thinking about for hivemind. (our limitation is that each service can only talk to one datasource). HiveMind allows multiple interceptors in a stack. There are examples of them performing logging operations, and more interceptors are on the way. 4) All our configuration is in XML resource bundles. This allows locale based config for the core server behaviour which we can control on a per session basis (although we haven't needed to yet). We chose to separate configuration from the services themselves, different to hivemind. The system we use allows single Strings, Lists, Maps and raw XML to be loaded from the resources by the program. There is no auto-bean conversion though which is nice in hivemind (although it only takes one line in our code). Having unified module deployment descriptors enahnces the IoC aspects of HiveMind. The framework, as container, can set properties of core implementations to configurations or other services. Proxies get in there to keep unecessary work from occuring until actually needed, and to defuse cyclic dependencies. Additionally, having interlationships between modules is very powerful; especially for pluggability reasons. For example, module A could define a DAO interface and service, and modules B and C (only one available at runtime) would contribute an implementation of the service. HiveMind also feeds on itself ... services are used to construct other services. BuilderFactory is the IoC engine; it constructs core implementations and can set properties of the impl to other services and configs. EJBFactory creates a core impl that's a wrapper

I'm not an aspect guru (not yet), but I believe a method introduction (at least in AspectJ) can take into account who the caller is. So, the interceptor could make the method operate different dependeing on whether, for example, the method was invoked be test code, by the container, or by the object itself (recursively).

Re: [hivemind] Design comparison
From: Howard M. Lewis Ship [EMAIL PROTECTED] 2) The selection of which implementation to use is performed late. The selection is based on - data in the method arguments - the services in the stack calling this one - the configuration the method parameters. It acts like a big if statement. Those almost look like AOP method introductions; this doesn't have a parallel in HiveMind per se. Yes hivemind does not seem to allow multiple implementations for the same interface, and choose the one to use each time it is called. This late binding is a key part of this framework. --- The lookup is hidden from callers by a class that simply has all the interfaces as methods, performs the lookup and then calls the implementation. I'm not following this; in HiveMind services are represented by interfaces; the implementation of the interface may be a fabricated proxy or interceptor, or a user-supplied core implementation (or a fabricated core implementation). Yes, services are represented by interfaces, with an implementation that may be decorated with a fabricated proxy. To achieve this you need a lookup to get the correct implementation class for the interface. (In hivemind this is performed by a set method on the implementation, but that won't work for late binding singletons. --- Stephen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: [collections] Observed
How useful are these convenience methods? I added them, then removed them.
Trouble is that not every handler will necessarily use listeners (although
most will).
Synchronized - collection is always synchronized
Bounded - collection is always bounded
Predicated - collection is always predicated
Unmodifiable - collection can not be modified
Observed - collection is always observed
Observable - collection can be observed
Naming is dubious, but I guess Observable might be marginally better as the
observer is optional. Any other views?
Stephen
From: Michael Heuer [EMAIL PROTECTED]
Could you add methods to ObservableCollection and friends that forward to
the ModificationHandler,
public void addPreModificationListener(Object l)
{
getHandler().addPreModificationListener(l);
}
public void removePreModificationListener(Object l)
public void addPostModificationListener(Object l)
public void removePostModificationListener(Object l)
etc.
Also, before release, does anyone else want to weigh in on Observable vs.
Observed?

Subject: [collections] 3.0 release (1)
I am volunteering to arrange the 3.0 release of [collections], which
is
long
overdue.
I am currently:
- finishing the ObservedCollection code
- writing release notes
- trying to separate the primitive collections code
- rename SequencedSet to OrderedSet
- reviewing the bugzilla entries
Other tasks:
- write OrderedMap decorator (Hen)
- review Bag interface where it deviates from Collection
- see if MultiMap code on bugzilla can be integrated
Henri has volunteered to do the actual final builds and release to
Minatour/Mirrors, but (unless someone objects) I will manage the
release.

Re: [collections] Observed
On Wed, 17 Sep 2003, Stephen Colebourne wrote:
How useful are these convenience methods? I added them, then removed them.
Trouble is that not every handler will necessarily use listeners (although
most will).
It seems to me that the Handler is more an artifact of designing
flexibility into the implementation than something that a client (in most
cases) wants to concern themselves with.
You raise a good exception though.
michael
Synchronized - collection is always synchronized
Bounded - collection is always bounded
Predicated - collection is always predicated
Unmodifiable - collection can not be modified
Observed - collection is always observed
Observable - collection can be observed
Naming is dubious, but I guess Observable might be marginally better as the
observer is optional. Any other views?
Stephen
From: Michael Heuer [EMAIL PROTECTED]
Could you add methods to ObservableCollection and friends that forward to
the ModificationHandler,
public void addPreModificationListener(Object l)
{
getHandler().addPreModificationListener(l);
}
public void removePreModificationListener(Object l)
public void addPostModificationListener(Object l)
public void removePostModificationListener(Object l)
etc.
Also, before release, does anyone else want to weigh in on Observable vs.
Observed?

Still to do:
- ObservedMap
- write observedXxx() methods for CollectionUtils et al
- write release notes
- tidy up the Bugzilla entries
- MultiMap changes??
- Bag interface changes??
- OrderedMap decorator?

Subject: [collections] 3.0 release (1)
I am volunteering to arrange the 3.0 release of [collections], which
is
long
overdue.
I am currently:
- finishing the ObservedCollection code
- writing release notes
- trying to separate the primitive collections code
- rename SequencedSet to OrderedSet
- reviewing the bugzilla entries
Other tasks:
- write OrderedMap decorator (Hen)
- review Bag interface where it deviates from Collection
- see if MultiMap code on bugzilla can be integrated
Henri has volunteered to do the actual final builds and release to
Minatour/Mirrors, but (unless someone objects) I will manage the
release.

Re: [PATCH] Reworked digest auth
Take 2: - DigestScheme requires a nonce in every challange now (according to RFC 2617) test cases changed accordingly - included Olegs feedback After reading RFC 2617 I came to the conclusion, that we need to rework out authentication mechanism to support stateful authentication retries. Digest Authentication requires you to keep track of the number of times authentication has been retries (NC) and to calculate some values only on the first time etc. This can be achieved by making the DigestScheme more stateful (a1) and by changing authenticator to keep the DigestScheme instance across retries and pass in the challenge each time. Odi Oleg Kalnichevski wrote: Odi, The patch looks fine to me. There is just a few minor points that I would like to be considered before the patch is committed: - DigestScheme#DigestScheme( String ) constructor should probably log a warning message or even throw an exception if it encounters an unrecognised 'qop' element. Currently they are just silently ignored. - Use StringBuffer to concatenate strings in DigestScheme#createDigest( String, String ). - A test case for unsupported qop in HTTP Digest authentication would be nice. - The patch makes a few public methods private (quite appropriately in my opinion).

Seeking help using Cookie and Session
Hi I am write a small client/server web app to understand more about
httpclient/cookie/and httpsession.
On the httpclient side, I use a get method to keep calling a servlet on server.
clientcode
HttpClient client = new HttpClient();
GetMethod method = new GetMethod(url);
while ( !done ) {
client.executeMethod(method);
if (method.getStatusCode() == HttpStatus.SC_OK) {
method.getResponseBody();
method.releaseConnection();
} else {
System.out.println(Unexpected failure: +
method.getStatusLine().toString());
done = true;
}
method.recycle();
method.setPath(url);
sleep(sometime)
}
/clientcode
on the server side, the doGet() method use this
servercode
public void doGet(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException {
request.getSession();
}
/servercode
The first loop, the client is happy. I found a cookie in the response.
After that it throws the following warning message in my lo4j
warning-snippet
06:22:37,843 - WARN org.apache.commons.httpclient.HttpMethodBase - Cookie reject
ed: $Version=0; JSESSIONID=6D150D24B3D022F9AB835EF4E0AFEC5E; $Path=/webtest. I
llegal path attribute /webtest. Path of origin: http://localhost:8080/webtest
/webgenservlet
/waring-snippet
On server side, new session is created for each request
Questions are:
Why server keeps creating new session instead of reuse the old one?
What does it mean regarding the Warning.
Advices are greately appreciated.
Happy Coding
-Dan
RE: Seeking help using Cookie and Session
Dan,
Before I could give you a more precise answer, I would need some additional input from
you.
- What kind of cookie policy have you been using? Have you tried using browser
compatibility policy?
If unsure, you may want to consult our cookie guide:
http://jakarta.apache.org/commons/httpclient/cookies.html
- What kind of servlet engine are you running on the server?
- Could you produce the wire log of the session in question.
Take a look at the logging guide for the instructions on how to activate wire
logging:
http://jakarta.apache.org/commons/httpclient/logging.html
Cheers
Oleg

Re: Seeking help using Cookie and Session
Dear Eric and Oleg,
I put in the code to handle brower compatibility cookie.
Now it works. Thank you Thank you.
Eric, thanks for the advice. I took out recycle call
and handle releaseConnection correctly.
Thanks for every thing

Subject: Re: Seeking help using Cookie and Session
A follow-up question, directed towards the rest of the group
Shouldn't recycle be deprecated for the 2.1 release? Seems like we've
discussed it before, and all it gives us is a chance for uses like the
following, where my first reaction was that maybe the recycle call
didn't work properly. I don't think it adds much for performance, and
it makes the API more confusing, I think.
To Dan,
You might want to structure your call slightly differently, as well:
try {
client.executeMethod(method);
// do what you want here...
}
finally {
// guarantee that you always release the connection - critical if you
switch
// to MultiThreadedHttpConnectionManager().
method.releaseConnection();
}
-Eric.

Re: HTTP/1.1 status 100 help needed
Mohsin, Do you know what kind of HTTP server runs on the server side? The HTTP server appears to be using the 'expect: 100-continue' handshake even though the client did not request it. You may what to try the following measures: - activating 'expect: 100-continue' on the client side - using HTTP/1.0 Oleg On Wed, 2003-09-17 at 19:40, Beg, Mohsin wrote: Hello, I have the following code snippet that seems to never return from httpClient.executeMethod().

RE: HTTP/1.1 status 100 help needed
Oh. well, I knew it. This is a very strange quirk on the part of Jetty, which once was reported as a bug, but Jetty folks were not too enthusiastic to fix. Anyways, try this: PostMethod#setUseExpectHeader(true) and see if that makes any difference. If not, try disabling HTTP/1.1 support altogether: PostMethod#setHttp11(false) If nothing helps, you may have to consider upgrading Jetty to its latest stable version (4.2.12 as of writing).
