RE: Re(2): Application client log in
You are probably missing application-client.xml, and
orion-application-client.xml; they have to be in a META-INF directory
relative to the source root of your client. You should be able to find the
apropriate tags in the orion docs and on the sites referenced before.
In my own situation, I call RoleManager from an ejb which acts as a facade
for my own security interface to make it independent from the underlying
appserver (I like using Orion, but many potential clients require that it
runs on the appserver of their choice ...) - so my xml files reference my
Bean and not the RoleManager, which is called by my Orion-specific
bean-Implementation.

RE: Off-topic: UML Tools...Help!!!
I can't say anything about Select, but we are using (Ir)Rational Rose here - a sometimes harrowing but necessary experience. Harrowing, because of numerous littlebugs in the software, workflows which work only under certain circumstances and not others, and certain features only partially implemented (like roundtrip engineering). Necessary, because in any medium size or larger project the UML models and diagrams are an invaluable tool for understanding what's going on. I personally like to first look at the big picture, than hack up a few prototype implementation classes, and then combine them and make model and class design coherent. Rational certainly does allow us to do this (although not as easily as we would wish). Of course it integrates better with other rational tools (e.g. clearcase) than other UML modeling apps. I have been using MagicDraw a bit, mostly for reverse engineering which was not quite as well supported by Rational. It doesn't have the number of features that Rational has, but is certainly an interesting alternative for smaller projects (and much less expensive). I have to amend that we are in the process of installing the latest update of Rational, which seems to take care of many concerns that we had and adds features like better roundtrip engineering, better integration with tools like jbuilder, andJSP support (caveat emptor - we have not used this version yet, will know more in a couple of weeks) which can be a major headache because it doesn't easily fit in the typical class model. So despite my irreverence, (ir)rational Rose helps us as a group to document the model and keep track of the overall structure of the project. If you go with Rose, make sure it's the latest version - it certainly seems to make life considerable easier (and be less irrational) Cheers --peter P.S.

RE: Invalidating session .. removing JSESSIONID cookie
Kris, for most needs I could think of you shouldn't have to worry about the cookie at all. session.invalidate() will terminate the session, so if a user attempts to access a protected resource after a page executes this statement they will be required to login again. I do seem to remember, though, some funny behaviour if some output was written to the page before the invalidate statement. The cookie itself is transparent to the Application Programmer, afaik - e.g. the Http server is supposed to switch automatically to URL based sessionId if the browser has cookies turned off. As someone commented in an earlier post, by setting the page directive session=false, no HttpSession object will be created for this page. Don't know whether this would achieve what you are looking for. --peter -Original Message- From: Trujillo, Kris [mailto:[EMAIL PROTECTED]] Sent: Tuesday, December 04, 2001 2:58 PM To: Orion-Interest Subject: Invalidating session .. removing JSESSIONID cookie Has anyone had any success with invalidating a session and removing the JSESSIONID cookie from the users browser (without requiring the user to close their browser)?

Let me give you some context: Although I have some past experience with Orion (servlets, beans, jsp), I've never used its Data Sources, so I know next to nothing about them. And, although the community and documentation have improved of late, Orion's documentation is still pretty sparse. When it came time to spend some time with EJB, I moved over to JBoss, which has stronger documentation, for a while, and while on JBoss, I started making use of the Microsoft SQL Server driver beta, which has proved to be quite reasonable (which is not too surprising, since it's the Merant driver). Due to some performance issues, I wanted to see how the application we're working on would run under Orion, so I downloaded the latest, and started to try and configure it. The basic steps were still pretty easy, but now I'm stuck on the data source - no matter what I do, I can't seem to get Orion to recognize the SQL Server driver. Has anyone tried it yet? Am I missing something obvious? I put the driver JARs (three of them: msbase, msutil, mssqlserver) in orion/lib. I modified the data-sources.xml to use the driver, as follows: data-source name=MicrosoftSqlServer location=jdbc/SqlServerDS connection-driver=com.microsoft.jdbc.sqlserver.SQLServerDriver url=jdbc:microsoft:sqlserver://panthro:1433;DatabaseName=dbVoicenetDevGeoff ;SelectMethod=cursor username=user password=password inactivity-timeout=30 class=com.evermind.sql.DriverManagerDataSource / When orion starts, it says the following: Error initializing data-source 'jdbc/SqlServerDS': DriverManagerDataSource driver 'com.microsoft.jdbc.sqlserver.SQLServerDriver' not found What does this mean? It can't find the driver? The JARs are in orion lib, I've checked that several times, including that the driver name is right, and the class is in the JAR. I can't swear that Orion is loading the JARs, because it doesn't put that out to the console or log files, so I don't really know that it's doing that, but I'm assuming it is. It does say 'DriverManagerdataSource driver', so perhaps the driver isn't what it's expecting. Should I be using another class? Based on the descriptions in the API docs and the Hypersonic example, this seems like a reasonable class to use. Suggestions? Anyone know where I can go from here?

I changed the batch file to set CLASSPATH=D:\ExtraJARs\ejb.jar;.;D:\ExtraJARs\orion.jar;D:\ExtraJARs\jndi.ja r java HelloClient After the change I get the following error javax.naming.NamingException: java:comp/env namespace is only available from within a J2EE component at com.sun.enterprise.naming.java.javaURLContext.getComponentContext(../../src/ share/com/sun/enterprise/naming/java/javaURLContext.java:392) at com.sun.enterprise.naming.java.javaURLContext.lookup(../../src/share/com/sun /enterprise/naming/java/javaURLContext.java:51) at javax.naming.InitialContext.lookup(Unknown Source) at HelloClient.main(HelloClient.java:9) Can anyone explain why it works when I use the three JARs from the H:\oc4j\j2ee\home directory but doesn't work when I try to use the copied JAR files.

RE: session bug
If I read your output correctly, your session object is still there in
Tomcat after the invalidate; only when you do a new getSession() a new
session ID is obtained. I have not read the spec on what the behaviour
should be, but the required behaviour may only say that at the *next
incoming request* the session object is not available any more.
Anybody out there took a peek at the spec?

Subject: session bug
Hello everyone!
I think I have found bug in orion 1.5.2.
There is problem with sessions. When I invalidate session and then get new
session, sometimes (not always) I get same invalidated session.
Does anybody have same problem? Any solution except that I remove all data
from session?
Thanks in advance.
Here is code that demonstrates bug:
session = request.getSession(true);
System.out.println("session = request.getSession(false);\t" +
session.hashCode());
System.out.println("session = " + session);
session.invalidate();
System.out.println("session.invalidate();\t" + session.hashCode());
System.out.println("session = " + session);
session = request.getSession();
System.out.println("session = request.getSession();\t" +
session.hashCode());
System.out.println("session = " + session);
Orion's output:
session = request.getSession();2935133
session = HTTP Session AKAEMHOGAJOD
session.invalidate(); 2935133
session = HTTP Session AKAEMHOGAJOD
session = request.getSession(); 2935133
session = HTTP Session AKAEMHOGAJOD
Exception is
java.lang.IllegalStateException: Session was invalidated

request.getInputStream - more
Title: After some experimentation I found that the availability of the request input stream is dependent upon the request mime type. E.g. submission from an HTML forms default mime type is *not* available, while text/xml-SOAP or multipart/form-data is.I believe this is not the correct behaviour, because the servlet spec(2.2) says:Posted form data is only read from the input stream of the request and used to populate theparameter set when all of the following conditions are met:1. The request is an HTTP or HTTPS request.2. The HTTP method is POST3. The content type is application/x-www-form-urlencoded4. The servlet calls any of the getParameter family of methods on the request object.If any of the getParameter family of methods is not called, or not all of the above conditionsare met, the post data must remain available for the servlet to read via the request's input stream. I have submitted this as bug 607. --peter
RE: Running Orion as Win 2000 services ???
JNT is a viable and simple alternative - http://www.eworksmart.com/JNT/ problems I encountered with it are that shutting down the service from the W2K services console hangs (after shutting the service down, so it's no big problem). A larger issue is that it uses the "default JVM", which on one of my machines is 1.2.2 (company required 'legacy app'), in which Orion doesn't run. Have not been able to figure out how to change that, even after consulting with our Microsoft contact. Anyway, if you have 1.3 or greater installed, it's easy to install and remove, and has worked fine. --peter -Original Message-From: Eddie [mailto:[EMAIL PROTECTED]]Sent: Friday, September 14, 2001 5:22 AMTo: Orion-InterestSubject: Running Orion as Win 2000 services ???

reading the ServletInputStream
I am trying to read the 'raw' http request that is submitted e.g. by a FORM.
I assume that ServletInputStream should contain the unparsed HTTP request.
public class RequestEchoServlet extends HttpServlet {
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
ServletInputStream in = request.getInputStream();
int character;
PrintWriter out = response.getWriter();
while ( (character = in.read()) -1 ) {
out.print( character );
System.out.print( # );// never gets here
}
System.out.print(character);
out.flush() ;
out.close() ;
} // of doPost()
}
in.read() immediately returns -1. What is wrong - my assumption or my code
(or both ...)
Thanks

Hi:
I've been trying to send the authenticated app client's Subject to
a RMI Activatable server in another JVM. In the app client, I run the
follwing:
AccessControlContext ac = AccessController.getContext();

However, sbj turns out to be null. Is it because ac is NOT the Subject

RE: FORM based authentication with form-login-page as a JSP
Would be interesting to control where a user goes, e.g. always redirecting them to the home page. Unfortunately, I don't have an answer to your question, just another observation: you don't even have to submit the page to j_security_check (see e.g. atm/atm-web/login.jsp) - orion -knows- where to send the request from the page specified in FORM based authentication. The regular case would be that the same page is served (without specifying the ACTION attribute to the FORM), but Orion nicely processes your request and does the 'appropriate' thing. I have not had time to try to look inside orion to find out what they are doing internally.

I have set the form-login-page in the web.xml of the war file to point to a jsp file in my war file. I have setup constraints against different jsps in the war file (/foo/foo.jsp, /foo2/foo.jsp, etc). When a user invokes any jsp without being logged in the login jsp is displayed. The user enters the userid/password submits the page to j_security_check, is validated and redirected to the requested page. My question is ... Has anyone ever tried discovering the page that the user is trying to access from within the jsp page referenced as the form-login-page? I have tried checking the HTTP headers and session, but have not discovered it being saved anywhere. Usually when a page invokes another page the HTTP header REFERER exists with the URL to the previous page. I have noticed that once the user posts the login form on my login.jsp to j_security_check and is authenticated they are redirect to the correct location .. correct location being back to the page they wanted to access originally. This would mean that it has to be somewhere, but where??

I added the jndi.jar to the classpath for my client in WebStart, but no luck. I tried other namespaces, e.g. java:, but so far without success. If the VM cannot figure out that I've got a j2ee app client, do I have to use RMIInitialContextFactory?

Subject: Re: External EJB Client
It seems like you are using the ApplicationClientInitialContextFactory
without actually packaging your code as an Application Client. The
Application Client concept is part of the J2EE framework and an
application Client is deployed much like other modules. One of the
things needed is the deployment descriptor application-client.xml
It seems that you are copying this descriptor to the ejb deployment
structure rather than to the client deployment structure.
If you intend to look up beans or other objects in the Orion JNDI tree
from outside the server I think that you should use the
RMIInitialContextFactory instead. I haven't used it myself so don't take
my word for it. By the way, I'm not sure of what classes are needed in
the client classpath to make this work. You might need to include the
full orion.jar.
