These are not exactly answers on your question, but some thoughts came
as I was reading it.
Why are you using sendRedirect() method instead of RequestDispatcher
object ? The one reason doing so I see would be to redirect *outside* of
your web app, but that solution wouldn't set any objects with "session"
scope. Thus, it's not your case. Do you work with Servlet 2.2 compatible
servlet container ? If so, read on...
The difference between them (sendRedirect and RequestDispatcher) is that
sendRedirect sends back to a browser a response that it should redirect
its request to another page/site which implies another request will be
sent by a browser. On the other hand, RequestDispatcher gives you
possibilities to send a request forth and back (no matter how many
times) between web components just on the server side rather then
forcing to exchange information through the net as in previous case.
I'd rather write:
if (done == null)
getServletContext.getRequestDispatcher(relogin).forward(req, res);
assuming that req and res are HttpRequest and HttpResponse objects
respectively.
Also, I'm noticing a difference in the URL when I move
around the site in a SSL session now. URLs now look
like:
https://protected.company.com/Action?cmd=myaccount;jsessionid=Oa6HTKaeJpki3ZNlC_zHuKUEu80WAyXKdC7qPTT4plE=
I never had the "jsessionid=0a6H" before.
That's described in Servlet specification
(http://java.sun.com/products/servlet). jsessionid is reserved cookie
name being visible when your application uses HttpSession, but a client
(i.e. browser) doesn't support cookies. In that case, technique called
URLRewritting is being used and all it does is to rewrite URL so the new
URL includes jsessionid and a session is preserved.

Re: URLs in web apps
there is a difference between URLs that are resolved by the http server (i.e. those that are embedded in a page via href=) and those that are resolved by the servlet engine (i.e., when used with the servlet APIs or with JSP-tags that are compiled into such API calls). In the first case, "/" is the document-root of the http server (orion: whatever may be configured as default-web-site), in the latter case it is the context root of the current app. -Original Message- From: Kevin Duffey [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Date: Freitag, 1.

They used Orion as the apps server and found that the best way forward was to run each (there were twelve in total) webserver as a joint web-server/apps-server. Their, and my own experience, is that Orion is quite ready for the fully distributed, highly available environment. Orion is a great product, and I am sure that the current issues will be ironed out shortly. For me, Orion boils down to being realistic - do I really want to get all philosophical and make everything distributed to the nth degree, or can I afford to wait (and we're probably talking a matter of months here, I guess) for the full distributable/highly available version?

That's what I've said. It speeds up your application response because of missing additional requests just to get the required resource/page. It also happens in case of include, but workflow is opposite so your page collect all information before sending it back to a client. I'd not say it's a problem. If your client refreshes a page, depending on browser settings, there might be another request doing exactly the same thing as before, so the results might be the same as well. On the other hand, sendRedirect() sends a page with a header containing information that a browser must request another page being set in header. So, that's pretty the same as in above case when using RequestDispatcher as a browser refreshes current page - no matter if it came from sendRedirect() or RequestDispatcher. I didn't see any problems so far. Jacek Laskowski

Re: RMI from EJB, permissions in EJB
Hello,
thanks a lot for your comments. Just giving me a reference to the
documentation helped me a lot.
Dave refers to the spec that says:
" * An enterprise bean must not attempt to listen on a socket, accept
connections on a socket, or use a socket for multicast.
The EJB architecture allows an enterprise bean instance to be a network
socket client, but it does not allow it to be a network server. Allowing
the instance to become a network server would conflict with the basic
function of the enterprise bean-- to serve the EJB clients."
This implicitly says: The EJB may attempt to connect to a socket, i.e.
at some low level issue (maybe implicitly) the "connect" call of the
socket interface.
In 18.2.1.1 the spec defines that the EJB Container must be able to
grant to the enterprise bean instances at runtime...
...java.net.SocketPermission - grant "connect", "*" [Note A], deny all
other
Note [A] says: "This permission is necessary, for example, to allow
enterprise beans to use the client functionality of the Java IDL API and
RMI-IIOP packages that are part of Java 2 platform."
That is to say: The EJB is MEANT to possibly be a RMI client.
Indeed, a small standalone RMI client test application runs fine with
only the following policy granted:
grant {
// allows anyone to listen on un-privileged ports
permission java.net.SocketPermission "*:1024-65535",
"connect,resolve";
};
or, stated in other words, connect-permission is enough to be RMI
client.
OK, this to the spec. It should be possible then. But how?
Daves reference gave me the hint. Some lines below the cited text above
the spec says:
"The enterprise bean must not attempt to ... set security manager ..."
This evil forbidden thing a did in my code line
System.setSecurityManager(new RMISecurityManager());
I commented it out and - miracle - I could connect to my tiny RMI server
and everthing worked as had dreamed of it.
Problem solved.
But, referring to point 2 of my original mail: What the heck is the
server tag in rmi.xml meant to do? And why doesn't orion start up when
I set it?
Again, thanks for your valuable hints.

Ted Neward wrote:
Where do you see that? I don't read any particular restriction on making RMI
calls; you're not allowed to explicitly listen for any incoming socket
calls, but that's not the same.
When I stop to think about it, in fact, a reference to another EJB itself
may be a remote reference, so the EJB spec CAN'T, in my interpretation,
forbid RMI calls, because then a Bean could never refer to another bean in
any way.
I completely agree to this argument.
Is there some text I missed in that section? (I freely admit, I
just skimmed it just now--not a real deep read--but didn't see anything

I pass in mail.Client1Domain.com and inside my class I do the following: properties.put( "mail.smtp.host", "mail.Client1Domain.com"); properties.put( "smtp-host", "mail.Client1Domain.com"); // Not needed as far as I know I also turn verbose on so I can see what is happening. It always uses mail.mydomain.com! If I comment out the mail-session entries from my global application xml then it works fine as long as I pass in the value and explicitly set the mail.smtp.host as above. In other words, it seems to ignore the mail-session in the Clientxxx-application.xml files as I pointed the smtp-host entry in one of the application.xml files to an existing server, but a different one. When I explicitly set the entries it uses the entries I set, not the mail-session entries. Seems to only use the mail-session entries only if in the global application xml file and no where else. When in the global application xml file, it seems you can only use that one even if I explicitly set it to a different one. What gives? Sorry for the long email, but I wanted to be sure to give all the data. Dale Bronk

Re: URLs in web apps
Alternatively, you could use this syntax... html head base href="%= request.getContextPath() %" / /head body a href="file.jsp"click/a /body In general, the servlet engine automatically maps the directory name to the application, but references to URLs from standard HTML tags are not automatically mapped. When the base href tag is used, all relative URLs are resolved relative to this value. If your application is mapped to the directory "myapp", then in the example above the href would reference "/myapp/file.jsp". Mike Kevin Duffey wrote: I think your ok..but I use the request.getContextPath() in a "included" header file on all my JSP pages. I assign it to a contextPath string var and use it in all my href tags a href="%= contextPath %/path/file.jsp"click/a But, I believe the spec allows relative paths to the root of the web app. So, if your root is /, and the dir is i3-web, and you have a linke to /path/page.jsp, it would be from /i3-web/path/page.jsp. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Kurt Hoyt Sent: Thursday, August 31, 2000 7:31 PM To: Orion-Interest Subject: URLs in web apps I've noticed an inconsistency in how URLs are used within the servlet engine in Orion.

Inheritance
I know the EJB 1.1 and 2.0 specs avoid (finesse?) the issue of bean inheritance, but has anyone tried doing anything that mimics inheritance using Orion? If so, can you share how you accomplished it? I have an object model that uses inheritance. I started with a trial version of PowerTier from Persistence, which does support inheritance, but also costs two arms and a leg just for developer licenses, not to mention the wheelbarrows of cash needed to deploy it. Orion has cleared all but two hurdles for us in our evaluation: servlets (I haven't tried one yet, but JSPs work, so I'm pretty sure we're OK there) and "inheritance". Thanks. Kurt in Atlanta
RE: HTTPSession timeouts in SSL environment
You know, I do use RequestDispatcher forward method further down in the code, but use sendRedirect if the client is not logged in (done==null). It is the only place where I use sendRedirect. Thank you for everyone's excellent responses on the merits of RequestDispatcher. However, the issue I was concerned about was the HTTP session timeouts. I have the session timeout set to 15 minutes in the web.xml file, but SSL HTTP sessions seem to time out after 60-90 seconds. After reading through some the mailing list, I tried setting my web app to "shared=true" and in the secure-web-site.xml file and now the HTTP sessions are working as planned. (timeouts after 15 minutes). What are the specific security ramifications of this setting? I have a unsecure site and a secure site. The unsecure site only has 3-4 pages. Maybe I should just make add to secure site and then only have one site? Perhaps this would clear my HTTP session timeout issue. Any thoughts on the security ramifications of shared=true and insight into my SSL HTTP session timout issue would be greatly appreciated. -Todd --- Magnus Rydin [EMAIL PROTECTED] wrote: Hi Chris, you are right. using a RequestDispatcher only redirects the request on the server side, wihtout informing the client. a sendRedirect() will ask the client to go to another page, thus changing header info and the whole thing. -Original Message- From: Christian Sell [mailto:[EMAIL PROTECTED]] Sent: den 1 september 2000 11:17 To: Orion-Interest Subject: Re: HTTPSession timeouts in SSL environment As far as I remember, there is another difference between sendRedirect() and RequestDispatcher.forward(). I once tested both alternatives, and I found that with forward(), the client never gets to know that he hase been sent to another page, i.e. the URL does not show, the reload button reloads the page from where the forward was done, etc. I think I remember there were even problems with links on the page.. The difference between them (sendRedirect and RequestDispatcher) is that sendRedirect sends back to a browser a response that it should redirect its request to another page/site which implies another request will be sent by a browser. On the other hand, RequestDispatcher gives you possibilities to send a request forth and back (no matter how many times) between web components just on the server side rather then forcing to exchange information through the net as in previous case.

RE: Which JDK to use?
I'm not on linux myself at the moment, but I'll try it when I have the opportunity. Thanks for the hint. I'm having trouble with glibc and java (Sun for now). I have glibc 2.1.3, JDK 1.2.2. When I try to start a Swing/AWT application I get a 'shared library not found' error. Anyone know something about that? non-GUI programs run fine. I'm not sure about that, but I think I've seen something similar in the past. The solution was to set LD_LIBRARY_PATH pointing out to $JAVA_HOME/lib or so and all started to be working fine. I can't check it out as I'm on Solaris, but I'm pretty sure it should help.

However, even then sometimes it won't die. Occasionally we have to give a kill -9 to the processes to get them to die. You do want to make sure that the old processes are completely gone BEFORE running orion again or else you may run into some problems (at least performance problems, and possibly some weird stuff going on).

RE: Inheritance
I know the EJB 1.1 and 2.0 specs avoid (finesse?) the issue of bean inheritance, but has anyone tried doing anything that mimics inheritance using Orion? If so, can you share how you accomplished it? EJB does not directly support inheritance - the main reason being that the Home interface for a bean could not fit into an inheritance model. There are however some alternatives. Firstly, suppose you have a Person EJB and want to extend it to become an Employee. You would create (and deploy) your Person EJB as normal, then have the remote interface and EJB implementation of Employee extend those of the Person. The home interface for EmployeeHome cannot extend PersonHome as it has a different return type for findByPrimaryKey() etc. Upon deployment, the EJB must be treated as a seperate entity, with a seperate JNDI lookup and all the appropriate fields redefined. This solution allows behaviours of beans to be reused, and once a entity has been found it is seen to the client as a 'is a' relationship and exhibits polymorphism. The problem lies in that find the EJB two seperate home interfaces need to be looked up. A solution to this is to create a session EJB that has reference to both beans and can use the finder methods of both entities and return an appropriate one. Another solution is to use the State (or Strategy) design pattern (see the GoF Design Patterns book - or just trawl the web for what it is). The advantage of this is that an object can change it's state at any time without having to be recreated and all the different states can be used in one entity. The best way to do implement this is to determine behaviours/fields that are common across all implementations of the inheritance model and place them in the main EJB, then place behaviours/fields that vary in your ConcreteState/Strategy classes. The problem with this approach is how to map keep a reference to the which state/strategy is being used and how to store the individual fields. Solution 1 is to simply serialize the class and store it as a field in the main EJB. This solves both problems but may not be ideal, particularly because the data is just stored as a bunch of binary data only recognizable to java (useless for finder methods). If you happen to be using an Java Object database you can perform write finder methods that use these objects - but most people aren't. Solution 2 to this is to create your own way of serializing/deserializing the objects. For example, the ejbStore() method could convert the state into an XML representation which could be stored in a normal text field, and the ejbLoad() could recreate it again. Another idea is to store the various properties for the state/strategy in a Map on ejbStore() - Orion can easily map a Map to a database with it's sophisticated OR features, and the table is easily queryable. If all else fails, use bean managed persistance. I'm sure there are many other methods and I would be interested to hear them. Inheritance is one of the draw-backs to EJB and if you are using it purely for object-relational (OR) mapping purposes, EJB may not necessarily be your best answer - but EJB will probably solve every other problem you have, so don't stray :) Relevant info: http://monsoon.wirestation.co.uk/or/ - Advanced OR mapping with Orion http://www.ambysoft.com/mappingObjects.html - Tips for OR mapping and creating own persistance layer http://www.helsinki.fi/~jplindfo/pattern/State.html - Diagram of state pattern http://www.helsinki.fi/~jplindfo/pattern/Strategy.html - blah -Joe Walnes
Re: Inheritance
There has been lively discussion on this topic in the ejb-interest mailing list. You can search the archives for inheritance here... http://archives.java.sun.com/archives/ejb-interest.html EJB inheritance has some general restrictions, though I don't think you'll find Orion to be the culprit. In summary, here are the restrictions as imposed by the EJB spec: - Bean-managed EJBs must return a primary key for an ejbCreate() method. Any class that inherits from the bean-managed EJB class cannot have an ejbCreate() method that returns a different primary key class. The restriction also applies to the bean-managed EJB's ejbFind() method. - Since EJB Home methods return a distinct remote interface, you cannot have a Home interface inherit from another Home interface that returns a different remote interface. In other words, BankAcountHome cannot extend AccountHome and attempt to return a BankAccount remote interface for a finder method whereas the AccountHome will return an Account remote interface. You can, however, use inheritance in EJB beans to refactor common business methods into a common superclass, and/or override base class behavior.

And this team have done very, very well. BTW, many people seem to be using later versions of Orion than the one from the download page. I presume there's a standard place where the "latest snapshot" can be found. Is this true? The reason I ask is that sometimes when Imodify a bean/servlet .java file into the WEB-INF/classes dir and reload the JSP page, I get a long stack trace that "seems" to indicate a problem with the code. I've discovered that if I reload another plain JSP page and then reload my page-that-calls--my-updated-bean, it suddenly works. This may be an old bug/feature that has been fixed in a later release.

Me again. A general question - sorry about this.
Hiya, Got to produce a demo as a proof of concept to get Orion in place before Friday this coming week, so I'm getting a tad frantic. My apologies if I'm asking dumb questions. I have an issue sort of about URL rewriting. (not baking cookies) My app (see the current one at http://smartoffice.com.au - no comments please! I know it needs work) has a number of business requirements that allow a user to browse the site loading up a cart and potentially 'logging-in' and retaining the cart. I assume everybody is familar with this. The site has several "sub-sites" which handle different areas. For example, non-secure, ssl and 'admin'. I'm going to setup a client that can run in Sydney and connect via RMI/IIOP to the server and databases in Melbourne. To make life a bit more manageable, I'd like to have the ability to 'munge' the URL such that a path points to a servlet which picks up the rest of the URL via getPathInfo() or whatever and gather useful information as a precursor to actually running the JSP page. For example: http://blah.blah.com.au/site/this/that.jsp and http://blah.blah.com.au/admin/a/bit/deeper.jsp Where 'site' and 'admin' are the servlets and 'this/that.jsp' and 'a/bit/deeper.jsp' are the 'actual' pages that get actioned by the respective servlet. The 'admin' servlet for example could request a seperate structured secure login process, while the 'site' servlet simply gathers cookies, DSNs etc and runs the JSP. I know this is possible, but be damned if I can figure out how to set it up in Orion. I've read books, sites and fiddled around till I'm blue and I'm obviously missing something very obvious. If anybody has any suggestions (besides sticking my head in the oven) I would be most appreciative. A reference to a book, paper or website would be helpful also. Just in case I have it but can't find it, the books currently surrounding me are: Java Servlets by example- Williamson Professional JSP- (Various) Wrox [Where I found out about Orion] Developing Enterprise Apps - Asbury and Weiner Pure Java 2 - Litwak Java 2 for Professionals- Morgan Build Java Enterprise J2EE - Perrone and Chaganti Sun's dev packs Kimbo.
