folks, have you thought about this? please give it some thought, and share your ideas with the group. when do we want to try our next im conference? i vote for sunday night - i actually have a 3-day weekend, and i'm taking the whole 3 days for a change (never at ee). let's say 9 pm? for anyone planning to attend, please respond if that time doesn't work for you. we don't really have an agenda - other than our very definite shift in focus towards an xml application server/xml messaging server. - r --- chris harris <cjh...@ho...> wrote: <HR> <html><div style='background-color:'><DIV>Team,</DIV> <DIV> </DIV> <DIV>In order for us to conjure up a compelling value proposition that ties in well with the prototype that is being built, we thought it would be a good idea to solicit feedback from the team. </DIV> <DIV> </DIV> <DIV>Poll question:</DIV> <DIV>Our goal is to determine what 5 areas of functionality traditional application servers lack over what we'd like to produce, an XML-centric Application Server.

wow - read this article in particular. this more or less sums up where i want to take this application. http://dcb.sun.com/practices/profiles/ecquaria_prof.jsp another article relates using soap for transport and ejbs to proxy between services. i am beginning to see more clearly one of the major strengths of what we're doing (building an xml app server): why incur the heavy lifting that an app server with ejbs has to go through? ejbs are just a distributed component model; well, so are web services: just another spin on distributed component models. but, they're more lightweight - easier to build, easier to configure and deploy, easier to maintain than ejbs. i see a real place for xml app servers ("web services servers") - it's an up and coming market that we are poised to launch into. we just need to make the necessary pieces come together at the same time: some usable prototype code (we're getting there), good presentations, and a good business plan. - r --- Robert Prince <ton...@ya...> wrote: > we need to be all over this stuff: > > http://dcb.sun.com/practices/webservices/ > __________________________________________________ Do You Yahoo!?

i've posted the notes from the 1st online/im conference we had last night - they're on the sourceforge docs page: https://sourceforge.net/docman/?group_id=32341 check it out - we decided we're going to do a conference like this once/week. starting next time, i'll post the decisions, and also the actual dialog from im, cut/pasted in. we decided not to do that this time because we were talking shit about too many people. - r __________________________________________________ Do You Yahoo!?

It is based on two major components, the <A href="http://www.infonyte.com/prod_pdom.html">PDOM engine</A> which is a persistent implementation of the W3C DOM (Document Object Model) API, and the <A href="http://www.infonyte.com/prod_xql.html">XQL engine</A> which is a web-aware query engine supporting the XQL query language. </P> <P>The lightweight implementation requires only an off-the-shelf Java runtime environment. Having a remarkably small footprint for memory, storage, and CPU, it can be deployed on a wide range of hardware platforms and operating systems ranging from large scale servers to embedded systems and small devices. It is well suited for distributed application architectures which require flexible and queryable XML-based document/data repositories. Likewise, it can serve as a solid base for CD-ROM products. </P> <P>With its integrated support for HTTP and URL, Infonyte-DB also enables the generation of scalable, multi-user server applications built on Javasoft's Servlet technology. A particular strength of Infonyte-DB is the support for a seamless integration of existing web information services into your value added information products. A number of customers from the automotive, eCommerce, document management, and mobile/embedded systems industry ship Infonyte-DB as a software component in their products today. </P> <H2>Features</H2> <UL> <LI>W3C <A href="http://www.w3.org/TR/1998/REC-DOM-Level-1-19981001/" target=_blank>DOM Level 1</A> API, XML documents stored in database files, transparent for the application <LI>supports <A href="http://www.w3.org/TandS/QL/QL98/pp/xql.html" target=_blank>XQL'98</A> with extensions for variables, multi document queries, restructuring of query results, full text search, result construction, and sequencing <LI>automated and transparent indexing on document structure <LI>stores well formed XML documents; no additional DTD mapping etc. required <LI>self contained, no additional backend storage needed <LI>small footprint: database file size 30%-100% compared to textual XML, main memory usage 800K minimum, 16MB main memory recommended for ~100MB documents, ~300K jar file. <LI>stores database files up to 2GB file size (~2GB-6GB textual XML data) <LI>100% Java (Java 2 Platform) <BR>-Chris</LI></UL></DIV> <DIV></DIV> <DIV></DIV>>From: Robert Prince <TON...@YA...> <DIV></DIV>>To: dcs...@li..., gr...@ya..., swi...@ne... <DIV></DIV>>Subject: [dcserver-developer] a persistence service using . . . <DIV></DIV>>Date: Mon, 27 Aug 2001 15:36:29 -0700 (PDT) <DIV></DIV>> <DIV></DIV>>a "native" xml database would be really super cool - <DIV></DIV>>and totally appropriate for one of our very important <DIV></DIV>>project/services. <DIV></DIV>> <DIV></DIV>>something for someone to look into if they feel like <DIV></DIV>>it. <DIV></DIV>> <DIV></DIV>>- r <DIV></DIV>> <DIV></DIV>>__________________________________________________ <DIV></DIV>>Do You Yahoo!? <DIV></DIV>>Make international calls for as low as $.04/minute with Yahoo!

all, i've been thinking about a couple of things that will require some sort of http support: - a web-based configuration interface; rather than create a complicated swing-based interface, i want to keep things initially very simple: just a parameter name/parameter value sort of thing. it's easy to make it look fancy/professional by sprucing up the html that surrounds the basic configurator stuff - using the dcserver to implement a web services server (soap, uddi, wsdl); this will of course require the use of http i am inclined to want to embed a compact http server for these tasks rather than rely on an external server like apache+tomcat or something of that nature. really, i think in the long run we'll need to allow for both ways, but for now we'll just use an embedded http server. the one i'm thinking of is jo!: http://www.tagtraum.com/jo.html it looks like it's got a good feature set, and it's fairly simple to actually embed it (and of course it's open source, always a plus). we can shift gears and replace it with something else later. so, if someone wants to investigate embedding it for the configuration/admin portion, that would be great - send me an email and we can discuss it in detail. otherwise, i'll probably start on that after i write the scheduling/event service. - r __________________________________________________ Do You Yahoo!?

semi functional, anyway ;) it uses an all-java, embedded sql-based database called hsqldb, which you can find on sourceforge (sourceforge.net/projects/hsqldb). the interface is simple - it corresponds to the generic persistence interface defined in dcs.service.persistence.PersistenceService. generate the javadoc and check it out: "ant -f bin/build.xml docs" i've only tested the String store/load mechanism; i'll check out the byte[] and Object store/load stuff tomorrow or early next week, unless somebody else wants to play with it ;) keep in mind that i haven't done any kind of duration, load, or stress testing - all i know is it lets me store strings and retrieve strings ;) - r __________________________________________________ Do You Yahoo!?

the low-hanging fruit: - secure/encrypted enterprise-to-enterprise bulk data transfer (here's some technical info on the subject: http://lib.nevalink.ru/tcp_stevens/tcp_bulk.htm) the attention-getter: - rosettanet messaging server/state management system the cash cow: - erp and crm integration think about it. this is doable stuff. all we need to do is get the bulk data transfer operational, and the rosetta stuff operational for 1 or 2 pips. then we can shop around for money. - r __________________________________________________ Do You Yahoo!?

very interesting! i will give that a try. in any event, i don't see too much problem in specifying jdk1.3 if we must . . . by the time this gets serious (maybe 2 - 6 months from now, when we have some interesting services built), 1.3 should be less of an issue in terms of stability than it is now. - r --- Satish Reddy <rsa...@ho...> wrote: <HR> <html><div style='background-color:'><DIV> <DIV>I have observered that If we specify the JAVA_HOME as jdk1.3.1 and still use the rt.jar from jdk1.2.2, it runs fine without complaining about the method not found error. </DIV> <DIV> </DIV> <DIV>-satish</DIV> <DIV> </DIV> <DIV>>From: Robert Prince <TON...@YA...></DIV></DIV> <DIV></DIV>>To: Satish Reddy <RSA...@HO...>, dcs...@li..., gr...@ya..., swi...@ne... <DIV></DIV>>Subject: Re: [dcserver-developer] a persistence interface . . . <DIV></DIV>>Date: Sat, 18 Aug 2001 18:20:00 -0700 (PDT) <DIV></DIV>> <DIV></DIV>>thanks satish ;) <DIV></DIV>> <DIV></DIV>>that's funny, i am using jdk1.2.2 - the rt.jar i'm <DIV></DIV>>using is copied from 1.2.2, and my $JAVA_HOME is set <DIV></DIV>>to jdk1.2.2. i just recopied rt.jar, recompiled, and <DIV></DIV>>ran it to verify, and it works fine . . . ? i can't <DIV></DIV>>find in the dom4j docs anywhere what jdk version it <DIV></DIV>>requires - you'd think it would be in the faq, but <DIV></DIV>>it's not. <DIV></DIV>> <DIV></DIV>>- r <DIV></DIV>> <DIV></DIV>>--- Satish Reddy <RSA...@HO...>wrote: <DIV></DIV>> <DIV></DIV>> <HR> <DIV></DIV>> <DIV> <DIV></DIV>> <P>hi </P></DIV>>robert,<BR> I <DIV></DIV>>checked out the code and I build it was trying to run <DIV></DIV>>the Application.
