Re: IIS, Orion, virtual host
Paul, I'm sorry to say that I have no experience with IIS and configuration issues therein. I do know thorugh experience and education that each IP has it's own set of ports. That's why I gave my advice below. If you are trying to do something similar to Oliver (run Orion on a different IP but same port as IIS), then I would recommend trying my suggestion below. If you think you have IIS configured to only listen to one IP, then start it up and try accessing the second IP on the same port. If the IIS web site comes up, then it is configured to listen to ALL IPs on the box. I would read the documentation on IIS at this point. From what little I know of IIS, there are some pretty big security holes in it, which I guess if you keep up with the patches can be dealt with... Sorry I could't give you more hands-on experience.

Re: MVC/XML Framework Comments please
Hi, As we have also rolled our own solution, I'll just add my two cents. As Tim, we found that the existing frameworks didn't fit quite well into what we wanted to do, (that was even before Struts was created) and as we wanted to integrate other features... Following the Model 2-controller servlet approach, we have a centralised servlet, driven by an XML file, that specifies XML/XSLT sources for any given path. However, most of the times we are not generating XML in Java, but directly from PLSQL. We think that EJB is too much/too painful to develop for most of our applications so we developed a small library that allows us to generate the XML content directly from PLSQL. If you need to handle session values and the like, you can also use JSPs to generate part of the XML and integrate it with PLSQL generated XML. We also provide ways to modify the defined sources (XML or XSLT) on a per-request basis so it is quite flexible. We also use precompiled style-sheets, which, last time I checked, boosted our performance sometimes by a factor of three! Last detail I added to our XSLT cache is that precompiled stylesheets are stored through Soft References, thus preventing the cache from eating all the memory and providing a controlled degradation of service (not sure if that is the english translation ;)) We included also: .- a logging system, which we hope to be able to remove as soon as 1.4 provides something similar .- a flexible security system, which much more flexible that the one the JSDK spec. provides .- internationalisation, which allows us to change the config values depending on the language value .- browserization which also allows us to change the config values depending on the browser Agent and Accept strings. .- Our own connection pools, which we are thinking about replacing with another library... All in all... a .jar file of about 294KB The key point, IMHO, is to stick to standards as much as you can, and to allow different parts to be replaced when time comes. For example, we used to have a module that made the XSLT processing independent of the XSLT processor, now that JAXP 1.1 has done so, we removed the module and substituted it with JAXP. The better the standards, the easier to mantain our library. On the how to handle such a project side, we also follow the model of providing the designers with a set of static XML files so they can start playing with them while other people implement the logic. When logic is ready, you substitute XML_SOURCE=/.../static.xml with XML_SOURCE=plsql://.../package.procName and almost voilà ;). Almost because you still have to check that parameters are passed and things like that. We are pretty happy with it, as it allows us to concentrate on the real application (presentation-XSLT, logic-PLSQL/BDD) and we don't have to spend that much time developing Beans, interfaces... If we needed to, we would be able to use EJB, but for us it's been not worthy (so far). Just my 2ec, D. PD: We have had 5-6 applications with this system running production for a almost 1 year and half. We don't have big ones, but we have lots of them ;). Tim Endres wrote: We rolled our own servlet for this. I found none of the existing frameworks to properly address what we needed. It is not a complicated thing to write. An XML config file specifies the commands that get executed for any given pathinfo. The command is tied to an XSL stylesheet, which processes the XML that the command generates. Precompiled stylesheets are effectively XSL stylesheets that have already been parsed from the XML text into the DOM Node tree that is used by the XSLT processor. These compiled stylesheets are then Serialized out, and then Serialized back in, such that our code can then skip the cost of parsing the XSL's XML file, in exchange for the cost of serialization. tim. Tim, that sounds v.interesting. Forgive my ignorance but what toolkit are you using and what do you mean by precompile the XSL pages? Thanks, Trevor On Thu, 26 Apr 2001, Tim Endres wrote: We do exactly what you propose. A servlet drives lightweight commands. The commands get XML trees containing the HttpServletRequest information, and fill in a subtree with the XML results. This tree is fed into XSLT and the resulting HTML is sent down the wire. I prefer it over JSP by miles. We precompile the XSL pages, so we get really good performance. And the separation of content/presentation could not be better. tim. SNIP

RE: Re: IIS, Orion, virtual host
I must confess I was incorrect about the port issue. I had forgotten that I had moved my IIS to a different port when Orion was running. But I found the solution to the issue as well. Seems IIS listens on all IP by default even if you tell it to only listen on one port. The following tells how to disable this behaviour. I have tested it and it works. Thanks, Ron White PS. Please forward to the Orion list since my mailserver can't seem to find it. Socket Pooling, Performance, and Security Issues You might want to disable socket pooling if any of the following are true: You are not hosting a large number of sites. You have special security concerns. Socket pooling will cause IIS 5.0 to listen to all IP addresses, which might present a possible security risk for secure domains with multiple networks. In addition, both bandwidth throttling and performance adjustments will apply to all Web sites configured for the same port, for example port 80. If you intend to use bandwidth throttling or do performance tuning on a per-site basis, you will need to disable socket pooling. To disable socket pooling, type the following at the command prompt: cscript c:\inetpub\adminscripts\adsutil.vbs set w3svc/disablesocketpooling true The command prompt will reply: disablesocketpooling : (BOOLEAN) True Thanks, Ron White

clustering and web-site.xml, need one for each app?
Reading the orion docs for http clustering, step 3 left me with strange feeling. - Step 3: Configure your cluster islands Cluster islands are connected to a certain site rather than to a web application and to configure a cluster island, edit the web-site.xml file for the website your web-application is deployed on (for example default-web-site.xml file if you are clustering the default web-application)... - Currently all the applications we are testing are defined as sub applications of the default-web-site. ie: web-site host="ivan" port="8080" cluster-island="1" display-name="Default Orion WebSite"default-web-app application="default" name="defaultWebApp" /frontend host="ivan" port="80" /web-app application="eservices" name="eservices-web" root="/eservices" /web-app application="sessions" name="sessions-web" root="/sessions" / The line that got me thinking was "cluster islands are connected to a certain site rather than to a web application". Could this be whyour web applications are not sharing sessions when in their own directory,yet the same apps *do* share sessions when in the default-web-app directory??

Re: IIS, Orion, virtual host
I'm on Linux, and you can configure your machine to listen to multiple IPs. The NIC is originally configured with one IP when you set it up, but then you can go in and tell it to listen to more IPs. You can do this in NT and 2000 as well. In 2000, you just open up your network settings - TCP/IP properties - advanced. Now you can add multiple IPs to listen to. In Linux, I just use linuxconf. There's a section called IP aliases for Virtual Hosts. In solaris, you just put all the IPs you want to listen to in a file that is named after your interface and is located in /usr/local/if.setup.

RE: MVC/XML Framework Comments please
We too tried to use a liteweight persistence layer (jrf) with a few extensions, and found that Orion CMP was just as fast at most things, and significantly faster at relationships. I originally felt we needed to switch because some of our beans used bidirectional relationships implemented as get methods wrapping a finder method. This led to a pretty hefty performance hit. When Orion supports EJB QL and n:m relationships (1.5.0?), I think that performance issue will be lessoned. Until then, we had to denormalize our db a little while still use CMP. While looking at the various MVC frameworks, we too couldn't find anything to meet our needs. Struts and webWork were significantly more difficult to learn, which conflicted with the idea of making JSP easier for web designers, IMHO. Freemarker looked good until I found you had to write an adapter for each bean you wanted to expose for their template engine. We ended up writing our own MVC framework because of the unique requirements of our ASP based project. About 50% finished, we have been very pleased with our choice of Orion and CMP.

log4j and ejb
Hi, I'm trying to use log4j to log from an enterprise bean. I've been able to get a bean to log to stdout using the BasicConfigurator but am not able to get it to log using either the DOMConfigurator or the PropertyConfigurator. I believe Property and DOM configurators need a file to set up the appenders. Has anybody been successful in using a configurator othere than the BasicConfigurator with a bean? If so, how? Thanks, Todd
Does any one else see any problems with latest PDF2?
Looking at the latest spec PFD2, it appears that it is not possible to establish a unidirectional relationship between two entity beans in separate ejb-jar.xml files. With the removal of remote-ejb-name as a possible value for role-souce it makes integration of two packages impossible without the mess of taking and trying to merge two ejb-jar files into one. Scenario 1: We are developing an general accounting package. Our clients need to integrate with our package by establishing uni-directional relationships from their CMP Entities into what we provide them. Since they will not be altering our ejb-jar (except for deployment) how can they reference our beans? Scenario 2: Our accounting package contains a good number of CMP Entity beans. Since EJB A relates to B, and B relates to C, and C relates to D and E, and E relates to G and so on. It is not possible to separate the ejb-jar into multiple, smaller, ejb-jar files for the purpose of managing and controlling change. With over 100 EJBs a single ejb-jar becomes very unmanageable. Are there any solutions to these problems? Thanks. Alex Paransky Individualnetwork.com
Re: IIS, Orion, virtual host
Just seen this post (so many to look through!), and I essentially agree with Jeff. I would agree that the error is probably happening because IIS is binding to the same IP address as Orion.

Re: Re: IIS, Orion, virtual host
Just started subscribing to the interest group. Forgive me if talking nonsense, as I've not even used Orion yet, but I can definitely run IIS 5.0 and Apache web server on the same machine (virtual hosts setup for apache, IIS as the 'real' machine name). They both listen on port 80, and I can access home pages via a browser successfully. IIS 5.0 listens on port 80 by default (set in the website application settings - I don't know what happens if the port is left blank though!). Apache listens on *all* ports by default, but I've configured my virtual hosts to also listen on port 80.

Re: IIS, Orion, virtual host
I've done this before, and this does prevent multiple web servers from listening on the same port. I think that this is definitely a problem. A virtual IP does not have it's own port, but it is sharing the same port with the main ip. If a machine has main ip 1.2.3.4 and virtual 1.2.3.5 and 1.2.3.6, if I set a web server on port 80 on 1.2.3.4, also the other two ip address will be listening on port 80. There is no 1.2.3.5 or 1.2.3.6, unless you have additional interfaces, which are either virtual interfaces providing additional IPs on a single card, or multiple cards. This, obviously, unless you have 2 different network cards on the system. Or virtual interfaces running on the same real ether card. tim.

RE: can't find classes - help
elephantwalker,
Yes, I am aware of that. However, even though I am doing that - providing
entire path - the classes are still not found. That is what is giving me the
headache.
For example, let's say I have com.myclasses.Class. and
com.myclasses.Load
They are both there in the directory that I should be putting my classes in.
Load does a:
try {
Class.forName(com.myclasses.Class);
}catch(ClassNotFoundException c){
c.printStackTrace();
}
sure enough, it says that the class was not found. I have even put the class
that is running (Load) in the Class.forName(). It throws a ClassNotFound
exception as well.
I am going to put this code on tomcat just to see if it will do the same
thing.
Later,
Jim

RE: MVC/XML Framework Comments please
Is anyone here besides Tim using XSLT in their web application? I've been using XSLT for some time. I think a lot of the MVC dicussions show that people haven't yet hit on the right application model. MVC really works well in an environment with shared state... and ahred access to objects. The web makes that a bit harder than one would like. I use XSLT in 2 major modes: one as a JSP tag that can transform it's body content, and as a servlet that can transform the content of an arbitrary URL. One of the biggest design decisions is whether you are doing delivery or building an application: the architectures you'll choose are very different. You may be interested in a couple of papers I wrote a while ago: http://www.mind-to-mind.com/xml/articles/xslbeans/index.html I'm in the process (getting close to finished) with a prototype that provides real MVC using some of the ideas there.
