Re: POP3 and IMAP support
Bruce, I agree that my excuse for not writing unit tests is lame :) With mock objects we should be able to cover a reasonable amount of code for atleast the trivial test cases. Ex. A MockPOP3Connection that returnsa predetermined response that we can compare in an assert statement. But as u said nothing can be substituted for integration testing. What I suggest is that maybe we should write a sample application that connects to a mail server and sends and reads emails . Intersted parties will run that to test with there own environment. Weshould allow all values to be configured ( preferably via a GUI interface) so that they can customize it for their own environment. The advantage of this approach (if we have under examples)is that the end users will also have a go. And obviously report on the user list if something is wrong. Having said that I know we still cover onlythe basics with authentication (Rick has made some progress on this end). so once we cover a reasonable subset of auth mechanisms then we can publish this sample application. Till then lets use it among us. Regards, Rajith.

IMO, these two types of testingare distinct and serve two very different purposes.Unit testing deals with the concept of tests that are completelyself-contained, do not require external systems and services ( e.g.,databases, mail servers, etc.) and can be executed extremely fast(i.e., seconds). Unit tests are often run during the build processbecause of these characteristics which allows a large amount of these tests to be run in a very short amount of time.Integration testing is the exact opposite of unit testing. Integrationtesting deals specifically with the concept of integrating with otherexternal systems and services. Because of this, integration tests often take a much longer time to run (i.e., minutes) and should *not*be run during the build process. These tests require a separateprocess for running and should not be run for the standard buildprocess. /soapboxThanks for reading this far! I applaud you sticking with me through mysoapbox moment ;-).One of the most difficult situations with unit testing is usuallyencountered when writing test cases for code that requires an external system or service. To address this need, I usually turn to EasyMock(http://easymock.org/). EasyMock is a mocking framework that createsmock objects for classes and interfaces on-the-fly through the use of Java proxies. Because we're still using Java 1.4x with Geronimo,EasyMock 1.2 will need to be used. When I first began using EasyMock,without any knowledge of it, I was able to mock a persistence layer ina sizeable application that required Oracle in a single afternoon. Unit tests should be able to cover everthing in the JavaMail APIs thatwe're creating from end-to-end. But unit tests are no substitution forintegration tests. It's extremely important to also write integration tests that can be run against all of the most popular mail servers.Without these, there's no way to guarantee that we're playing nicewith those mail servers.I first thought about setting up a separate mail server on one of the gbuild.org machines that can be used solely for testing the JavaMailimpl. One big issue with this strategy is that with multiple peopleusing the same mail server, we're bound to clobber one another's work. Because of this, I abandoned the idea of setting up a mail server ongbuild.org in favor of each of us setting up our own mail servers inour own environment. In my situation, I'm setting up Postfix specifically for testing on one of my machines.Becoming experts on mail servers is one of the tasks we take on inwriting the JavaMail impl. That will most certainly require specificconfigurations and customizations to situate the tests. Maybe we should loosely agree to each use a different mail server just to coverour bases. At any rate, all custom configurations will need to bedocumented for each mail server to allow others to jump in ifnecessary. If you've read this far you deserve a trophy!

Re: WADI clustering
Ok, I am not fixed on multiple-active-sessions. But my concern is high availability with single-active-session model under high load conditions. As u pointed out, In the web world, clients commonly throw multiple concurrent requests atclusters, however, if we could assure total affinity, these would alwaysarrive at the same copy, avoiding the chance of a collision However if we use 100%session affinity then the chance of one server getting too many hits is possible (due to that being the primary and the LB indiscrimantely maintaining session affinity without due consideration for load). Thus a compromise of service quality is inevitable. The service will have to drop requests or degrade the service (provide only some of the services which are not expensive). So sometimes the cost of maintaining multiple-active-sessions may be less compared to the exceptional cost that has to be paid with a server crash thus increasing the load within the remaining nodes of the cluster. The cost in terms of money value of loosing revenue due to service un-availability could be higher than providing more memory, high-speed network infra which could handle the cost of serialization/desirialization of replicas and the overhead of a distributed locking mechanism without compromising performance. Thats why I said that we should provide both stratergies and the end-user can make an informed decesion based on there business requirments and load conditions within there cluster. We should avoid making those decesions before hand. Also allowing the idea of configurable active replicas will allow the end-user the flexibility of trying out both multiple-active-session and single-active-session models and see what works best for them. I would strongly advocate the idea of a Replication mgt abstraction API especially with some of the ideas Gianny provided on the thread. What do u think about that?? Have I made a case?? Regards, Rajith. On 1/18/06, Jules Gosnell [EMAIL PROTECTED] wrote: Jules Gosnell wrote: Oh Rajith - you've got me thinking :-( I'm not happy with the last answer - lets try again lets agree some points : 1) since changes made to sessions are made in app-space, apps are not written with the expectation that a change collision may occur and the container would not be able to avoid such a collision, it must never happen. 2) in order for a change-collision to occur multiple concurrent requests/invocations must hit multiple copies of the session In the web world, clients commonly throw multiple concurrent requests at clusters, however, if we could assure total affinity, these would always arrive at the same copy, avoiding the chance of a collision. There are various situations within the web tier that may cause the breakdown of affinity. Different loadbalancers handle these situations with varying degrees of correctness. I have decided that it is safer to assume that, whilst affinity is a substantial optimisation, it cannot be relied on 100%. So, in the web tier, it is possible for concurrent requests for the same session to arrive at different session copies. So we need a pessimistic distributed locking strategy to ensure that collisions do not occur. In the EJB world, we have more control over the load-balancer, because it is effectively built into the proxythat we supplied, and we could enforce the serial nature of invocations at this point. So it might be possible to move forward on the assumption that we don't need pessimistic locking (provided that no-one ever passes a session handle to another client). I'm going to give this a little more thought... I think the outcome will be that I can avoid some locking in the EJB world, but need to send the same messages anyway... but we'll see. Thanks for getting me to revisit this, BTW - if we do assume that we can rely on affinity 100% in the EJB tierthen I am still not sure that I see any real advantage in holdingmultiple active copies of a session. I guess you will have to explain to me exactly why you would want to do this.Finally, the locking system that WADI currently uses will only incurextra work, taking distributed locks, if affinity breaks down, so thecost of applying it to the SFSBs where, we hope for 100% affinity, should be 0.Jules Jules Jules Gosnell wrote: Rajith Attapattu wrote: More question if you don't mind. 2.)

Re: WADI clustering
Hi, Some of these questions came up after reading the thread on totem. However I started the new thread so that searching is easy and also want distract the intense discussions on totem with out-of-topic questions. Jules Gosnel wrote This is not something that is really considered a significant saving inWADI (see my last posting's explanation of why you only want one'active' copy of a session). WADI will keep session backups serialised, to save resources being constantly expended deserialising sessionbackups that may never be accessed. I guess actually, you could considerthat WADI will do a lazy deserialisation in the case that you have outlined, as primary and secondary copies will actually swap roles withattendant serialisation/passivation and deserialisation/activationcoordinated by messages.If you are running a reasonable sized cluster ( e.g. 30 nodes - it's allrelative) with a small number of backups configured (e.g. 1), then, inthe case of a session affinity brekdown (due to the leaving of aprimary's node), you have a 1/30 chance that the request will hit the primary, a 1/30 that you will hit the secondary and a 28/30 that youwill miss :-) So, you are right :-) So just to figure out if I understand this correctly. 1.) WADI only has one active and one-two backups at most (I assume the no of backups is configurable) 2.) WADI is built up on the assumption of session affinity. So the probability of missing the primary and the secondary backup(s) goes up as the cluster grows according to your example 3.) How does WADI handle a situation where there is no session affinity?? 4.) Have you compared the overhead of maintaining session affinity vs having R replicas (all-Active)to service the client. If, however, you did your deserialisation of replicants up front and thus avoided further messages when a secondary was hit, by maintainingall copies 'active' (I think you would not be spec compliant if you did this), 1.) What do u mean by spec here ?? Are u talking about the WADI spec? 2.) Assuming sombody wants to do session replication (All Active)instead of (one Active and n backups) is there provision within the WADI api to plug in this stratergy?

Re: ActiveCluster
Hi, Can somebody familliar with AC provide me some answers to the following questions. 1. Why is the AC api tied to JMS?? I guess a simillar question was raised within the totem thread. I was expecting a more abstract API independent of any platform and then the implementation to be some sort of platform specific. So there is a JMS impl on top of ActiveMQ or a JGroups impl. 2. Is there a doc that describes the architecture behind AC?? so I can read up and better understand it. 3. Currently in addition to the default impl,ActiveSpace and WADI is there any other impls/ use cases for AC?

And one way to do thisin a shared-nothing cluster is to use a quorum of N/2 + 1, where is themaximum number of nodes. Clearly it has to be the majority or else you can have a split-brain cluster. Do you think that we need to worry about situations where a piece of state has more than one client, so a network partition may result in two copies diverging in different and incompatible directions, rather than only one diverging.If you use a quorum or quorum-resource as above you do not have thisproblem. You can turn down the requests or let them block until thecluster re-discovers the 'failed' nodes. I can imagine this happening in an Entity Bean (but we should be able to use the DB to resolve this) or an application POJO. I haven't considered the latter case and it looks pretty hopeless to me, unless you have some alternative route over which the two fragments can communicate... but then, if you did, would you not pair it with your original network, so that the one failed over to the other or replicated its activity, so that you never perceived a split in the first place ? Is this a common solution, or do people use other mechanisms here ?I do believe that membership and quorum is all you need. Guglielmo

Re: Replication using totem protocol
This is a very educating thread, maybe Jules can incoporate some of the ideas into your document on clustering. I do have a few questions on Guglielmo's points onsession replication. (Not an expert so pls bear with my questions) 1. The user should configure a minimum-degree-of-replication R. This isthe number of replicas of a specific session which need to be available inorder for an HTTP request to be serviced. 1.) How do u figure out the most efficient value for R? I assume when R increases, network chatter increases at a magnitue of X, and X depends on wether it's a multicast protocol or 1-1 (first of all is this assumption correct ???). And when R reduces the chances of a request hitting a server where the session is not replicated is high. So the sweet spot is a balance btw the above to factors ??? or have I missed any other critical factor(s) ?? 2.) When you say minimum-degree-of-replication it imples to me a floor?? is there like a ceiling value like maximum-degree-of-replication?? I guess we don't want the session to grow beyond a point. 2. When an HTTP request arrives, if the cluster which received does nothave R copies then it blocks (it waits until there are.) This should indata centers because partitions are likely to be very short-lived (aka virtual partitions, which are due to congestion, not to any hardwareissue.) 1) Can u pls elaborate a bit more on this, didn't really understand it, when u said wait untill, does it mean a)wait till there are R no of replicas in the cluster? b) or until a session is replicated within the server thehttp request is received? 2)when u said virtual partition did u mean a sub set of nodes beingisolated due to congestion. By isolation I meant they have not able to replicate there sessions or receive replicationsfrom sessions from other nodes outside of the subset due to congestion. Is this correct?? 3) Assuming an HTTP request arrives and the cluster does not have R copies. How different is this situation from an HTTP request arrives but no session replication in that server ?? 3. If at any time an HTTP reaches a server which does not have itself areplica of the session it sends a client redirect to a node which does.How can this be achived?? Is itby having a central cordinator that handles a mapping or is this informationreplicated in all nodes on the entire cluster. information == whichclusters havereplicas of each session The point below gave me the impression that some of inventory has to be maintained centrally or cluster-wide (ideally in case controller dies). 4. When a new cluster is formed (with nodes coming or going), it takes aninventory of all the sessions and their version numbers. Sessions which donot have the necessary degree of replication need to be fixed, which will require some state transfer, and possibly migration of some session forproper load balancing. Again how does the replication healing/shedding works. Assuming nodes dieor comeback with carrying there state how does the cluster decide onadding or removing sessions to maintain the optimal R value. Where does the brain/logic for this sit?? Ideally distributable in case the controller dies. General comments/questions --- 1. How much does the current impls like WADI, ACluster and ASpace address those above concerns? 2.) What aspects of the above concerns can be addresed with totem better than other protocols? 3. Can SEDA like architechture solve the problem of deciding the value of R dynamically runtime from time to time based on load and network latency?? I guess the network latency can be messured with some metrics around token passing or something like that. Answers are greatly appreciated. Regards, Rajith.

By also treating nodes joining, leaving and dieing, as split and merge operations I can reduce the number of cases that I have to deal with.I would even add that the difference is known only to the application. and ensure that what might be very uncommonly run code (run on network partition/healing) is the same code that is commonly run on e.g. node join/leave - so it is likely to be more
Re: JMS Clustering in Geronimo v1

We did disscuss some issues with HA-JNDI, there is lot of disscussions on Web clustering, but other than that there is no direction or disscussion. This will confuse a lot of the end-users. Clustering is pretty darn important in any production-level deployment and if we don't give a clear idea to the community about where we stand or atleast the fact that we have recognized where we need to work or some sort of RoadMap the endusers will be very confused about the whole issue.

Re: [wadi-dev] Re: [Geronimo] Clustering
Jules, no I was thiking more of WADI and ActiveCluster as complimentry. Sorry if I wasn't clear on that. I was thinking about amerge more in terms of consolidating effort/energy into one area without been spread too thin. But there seems to be enough intrest and people and maynot be a concern. Also with the seperate mailling lists it may not be possible for people to participate in discussions that maybe benifit more than one area of clustering. But that can be avoid if General discussions are kept with the geronimo dev list. There is also an advantage of keeping them as seperate projects so people can work on there pet area by not really being slowed down by the overall administrativegoals of the merged project. (I mean like releases or when it should be taged/branched ...etc) and also they can maintain there own identity while collaborating with the overall effort. Do you have a pet clustering area ?

Like merging ActiveCluster and WADI or getting best of both worlds ? hmmm... not sure I follow you here... are you suggesting merging them because you view them as (a) competing or (b) complimentary technologies ? If (a), then I need to put you straight. WADI is a technology that builds on top of ActiveCluster (AC). AC provides basic clustering fn-ality (most importantly, a membership abstraction along with notifications of membership change). If (b), then, whilst WADI and AC could be merged, the current separation is along clear and modular lines and I see no advantage to collapsing the two projects into one. I think that there is far more reason to consider a merger between ActiveSpace (AS). AS is a project that also builds upon ActiveCluster to provide distributed caching fn-ality. The fundamental difference (and I stand open to correction from James here - I'm not very knowledgeable about AS) is that AS provides a host of optimistic caching strategies, whilst WADI (currently) provides a single, pessimistic strategy specifically designed for the management of state in web and ejb tiers, where the sum of the state in the tier is too great to be held by any single node. Because WADI and AC fulfil similar roles, I think that there is more to be gained by unifying their APIs and code-sharing between them. James, if you are reading, what do you think ? And also if we can define expectations/requirments for what we like for the next possible release (1.01 or whatever) in terms of clustering would give folks like me more direction as to where we should concentrate on?

It's awesome. I have more questions if you don't mind. Not very organized so bear with me :( Answers are greatly appreciated. JNDI implementation I guess what you are talking about is our own version of (at the least)JNDI Context implementation that is cluster aware and the lookup is based on the various strategies outlined in your email. (This is where I guess Apache directory can be leveraged to build our impl on top) Plus you are taked about passing in membership information to the client via a proprietary protocol or the client taking on itself to obtain membership info via configuration or an auto discovery handle. Instead can we have a proxy (which sits between the stub and skeleton) which will sit on our JNDI server and handle any membership issues. Sort of a proxy to a proxy :) Client -- stub -- proxy (which handles membership issues) -- skeleton -- EJB This will shield the client from having to have any knowledge whatsoever about the cluster membership. Assumptions - So the basic assumption is that it's a homogenous cluster. Does it mean that only the EJB's are present in every cluster or is it EJB's plus + other resources are available??? Does it mean that they all have access to the same data?? Like they could be pointing to the same database or a cluster of databases. SLSB I agree that in general we have a use case for non-sticky clustering. Again as you pointed out the SLSB is usually a façade for other more complex operations that may use system resources heavily. So in such a case are we going to collocate the resources and use a per-Bean or per-User (or per-Server?) sticky behavior here? If so that means we have to make sure that particular SLSB is sticky in terms of clustering. So it boils down to the fact that we are going to define a clustering strategy per bean (not bean type for ex SLSB or SFSB). Is this correct??? SFSB - As u mentioned most SFSB are going to be sticky, but if we do cluster the data associated with the session then we can use a non sticky algo. But u mentioned this is sub optimal? So is this really expensive?? Is it really worth looking at this option? Again I guess it depends on the amount of information that should be replicated which bring us back to the strategy of choosing a clustering type per Bean not by bean type. Entity I guess if the underlying data sources are clustered then we can use a non-sticky algo if not we have to use sticky. Is that correct for all scenarios??

RE: [Geronimo] Clustering
Jules, Sorry for the late reply and thanks for all the info!!! It's awesome. I have more questions if you don't mind. Not very organized so bear with me :( Answers are greatly appreciated. JNDI implementation I guess what you are talking about is our own version of (at the least)JNDI Context implementation that is cluster aware and the lookup is based on the various strategies outlined in your email. (This is where I guess Apache directory can be leveraged to build our impl on top) Plus you are taked about passing in membership information to the client via a proprietary protocol or the client taking on itself to obtain membership info via configuration or an auto discovery handle. Instead can we have a proxy (which sits between the stub and skeleton) which will sit on our JNDI server and handle any membership issues. Sort of a proxy to a proxy :) Client -- stub -- proxy (which handles membership issues) -- skeleton -- EJB This will shield the client from having to have any knowledge whatsoever about the cluster membership. Assumptions - So the basic assumption is that it's a homogenous cluster. Does it mean that only the EJB's are present in every cluster or is it EJB's plus + other resources are available??? Does it mean that they all have access to the same data?? Like they could be pointing to the same database or a cluster of databases. SLSB I agree that in general we have a use case for non-sticky clustering. Again as you pointed out the SLSB is usually a façade for other more complex operations that may use system resources heavily. So in such a case are we going to collocate the resources and use a per-Bean or per-User (or per-Server?) sticky behavior here? If so that means we have to make sure that particular SLSB is sticky in terms of clustering. So it boils down to the fact that we are going to define a clustering strategy per bean (not bean type for ex SLSB or SFSB). Is this correct??? SFSB - As u mentioned most SFSB are going to be sticky, but if we do cluster the data associated with the session then we can use a non sticky algo. But u mentioned this is sub optimal? So is this really expensive?? Is it really worth looking at this option? Again I guess it depends on the amount of information that should be replicated which bring us back to the strategy of choosing a clustering type per Bean not by bean type. Entity I guess if the underlying data sources are clustered then we can use a non-sticky algo if not we have to use sticky. Is that correct for all scenarios?? More Questions/Answers and discussions will help us to flesh this out more.

RE: IMAP Implementation
I had a strange problem with some of the IMAP commands. When I read from the InputStream after reading the last line from the response, program just hangs. I'm creating a BufferedReader from the socket input stream. I had the same problem. That's bcos the read method will be blocking until the data is available(unless there is connection error or timeout) and the code will block giving the impression the program has hanged. So what you should do is once you read the last line (there should be characters indicating end of response, for instance .CRLF for POP3) you should exit the loop without doing another read()(or else it will block). That way you know it's the end of response and proceed with the rest of the logic.

RE: Does there need to be a default web container?
I feel this debate is like do you like Coke or Pepsi? People will be more biased about the web container they use most of the time (forget about merits/demerits of each app) I think it's kind of useless to be arguing about this since both tomcat and jetty is available. So ppl will always choose to modify the config to have the container they like most. (This would have been an important debate, if we were going to include only one (either tomcat or jetty), but since both are included it doesn't really matter) Instead we should use the time to put more documentation on how you can change the web container. I think a lot of people will appreciate that.

I have a hard time with equating someone's clickety-click Mom with our average user...its ridicules, which was really what my previous response was directed towards. There are a lot of experienced J2EE developers out there who have only ever used full commercial stacks. Asking them to choose between two web containers is like asking them to choose EJB, MQ and Web Service implementations. They may pick Tomcat because they vaguely recognize the name, but having to make that choice will add anxiety to their install experience. I am sorry but I cannot agree here. I cannot believe there are many experienced *J2EE* developers who have no idea what a web container is. That is preposterous. Are there some? Sure - but I would say very few. However, in servlet 101...of which many of these un-knowledgable users would go, surely a mention of a web container, what it is, and what they can use (including books, articles, internet), they should have a minimal understanding of web containers. Geronimo is also likely to become popular in academic settings (both classroom and self-study) where people will need to install the server before they get around to learning what a web container is. The academic component is such a small microcosm in the grand scheme of users, this not even a reason to think its has a major effect of the overall user-base. We should push the direction of Geronimo towards what the community wants. If the community wants Jetty, give it to them. If they want Tomcat, then let them have this. Let the community decide.

RE: Who wants to write POP and IMAP transports? [status]
There is an implementation of all of the javamail api classes (including support for multipart-MIME messages). There's very little done in terms of protocol-specific implementation classes other than the SMTPTransport code that was just promoted out of the sandbox. Going by what Rick mentioned above, I assume that we do have an implementation for the Message classes. Or did u refer to the reference impl from sun?? If the Message implementation is done by Geronimo developers then we can extend and provide POP3Message and IMAPMessage implementations.

Is this client going to be plugged in as a portlet in the console? We're not building a client application. We're simply writing transports for the Geronimo JavaMail distribution to allow communication with mail servers via the various protocols. This effort has nothing to do with plugging into the console, it's far below that in the architecture sense. I have the code for an online imap client. It has basic functionality to grab folders and pull down messages. What are the feature requirements for this thing? The requirements here are to add POP3 and IMAP support to the geronimo implementation of the javamail apis. The end target is an implementation that functions exactly the same as the Sun implementation of the same. Everything implemented here needs to be under the umbrella of the javamail apis. So, for example, the local message format will be an implementation of the javamail message class. POP3 and IMAP each have their own defintion of a message as well. So this is one of the things we're providing. Currently, all that is implemented is an outbound smtp transport. This transport takes as input a javamail Message instance and send it to an smtp server. Missing right now is the capability for inbound messages (i.e., POP3 or IMAP). These need to be implementations of the javamail AbstractStore and AbstractFolder class. Currently, we have some stub implementations of these classes in the sandbox/mail directory, but they are currently just empty autogenerated classes. Somebody needs to fill in the blanks. Yes, in addition to modeling both POP3 and IMAP Stores and Folders, we also need to be able to connect to each server type and speak each protocol. In addition we'll need handlers that implement DataContentHandler for each message type including plain text, html and RFC822 (MIME messages). These impls just read messages from a javax.activation.DataSource and write messages to an OutputStream. The Sun JavaMail distribution provides both implementations, but it's not licensed in a way for us to make use of it. And like I said before, once we get these completed, maybe we can consider offering Maildir and Mbox implementations if we're feeling ambitious.

RE: Who wants to write POP and IMAP transports? [status]
Sure, Rick and Bilal as volunteered. I will take care of the POP3 protocol provider implementation. (more specifically javax.mail.Store and javax.mail.Folder implementations and support classes for POP3) Since Rick has already done work on the Message classes maybe he can help with the protocol specific Message Classes. Can you ??? I think Bruce is looking into IMAP, but he maybe busy with other things. So Bilal can you dig into IMAP stuff after checking with Bruce. And there is also the testing part. Any volunteers to test it and possibly expand on the unit tests?? Also Bruce did mention that, the intention is to move the JavaMail implementation to a sub project in the future. So maybe it's a good idea to make it Geronimo independent. Anyways a separation of concerns is always a plus point.

RE: Who wants to write POP and IMAP transports? [status]
Hi Rick, There is an implementation of all of the javamail api classes (including support for multipart-MIME messages). There's very little done in terms of protocol-specific implementation classes other than the SMTPTransport code that was just promoted out of the sandbox. Where can I find these classes have they been ported to the trunk from the sandbox??? I did an update now and all I see under org.apache.geronimo.mail Is a couple of GBeans for Stores, Mail and SMTP transport. As far as a JavaMail implementation is concerned I only see NullTransport.java. Can somebody help me figure out if I am looking in the wrong place?

There is a storage package and it has a message model based on the JavaMail Message object, but this is where the good news ends. The whole project is very UI application focused (e.g., prefs, mime, filters, search, addressbook, UI, widgets). There are no broken out transports so any IMAP that it might speak (and I don't think it supports much, if anything in the IMAP protocol) the POP3 and IMAP code is very much spaghetti'd together. What's more is that some of the classes import classes from the com.sun.mail.* package (bad, bad!). In addition, Grendel's manner of constructing a MimeMessage seems to be very tightly tied to it's UI implementation - no separation of concerns (big problem!). My conclusion was that Grendel is not usable either. This narrows the field to zero. There are some very good GPL implementations of everything we need, but alas, the GPL/AL incompatibility kicks in which leaves us to build our own implementation.

RE: Who wants to write POP and IMAP transports?
I guess we can later move it to it's own sub-project so other Apache users can use it as a standalone library. Just so that they don't go through the same trouble we are experiencing. -Original Message- From: Rajith Attapattu [mailto:[EMAIL PROTECTED] Sent: Saturday, December 03, 2005 7:58 PM To: dev@geronimo.apache.org Subject: RE: Who wants to write POP and IMAP transports?

RE: [Geronimo] Clustering
Jeff, Apologize for late reply, down with flu. Is high availability JNDI (or JNDI clustering) a concept brought up by JBoss?? Frankly I am no expert on this, so any pointers will be very helpful. I see that WADI is yet to implement this. So do u have any documentation on this? I assume we will follow the jboss concept closely, but hopefully to improve on it. Any help is greatly appreciated.

RE: [Geronimo] Clustering
Jeff, We maybe able to leverage the Apache Directory for the underlying JNDI aspect of it (I will look in to this, but might need help) How about the policy management portion of clustering service?? For ex Clustering strategy == Whether to use Sticky vs Random vs other load balancing mechanisms or are we allowing the user to choose a strategy from above. We can represent each clustering strategy as a GBean which the user can pick from (under the Clustering services GBean, I assume you have the whole clustering feature represented as a GBean ). So if somebody is not happy about the clustering strategy then simply write there own and add that as a GBean. Of course we will have to come up with a neat API for exposing the aspects that should be open for improvement. This will also help us to come up with better clustering strategies later on in the future without a major impact on the code base. What are your thoughts on this??? Everybody please help with ideas :) Regards, Rajith Attapattu. -Original Message- From: Jeff Genender [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 30, 2005 1:13 PM To: dev@geronimo.apache.org Subject: Re: [Geronimo] Clustering Rajith Attapattu wrote: Jeff, Apologize for late reply, down with flu.
