Oracle data-source connect
Hello,
I am new w/ Orion and I have the following problem:
I can't connect however it seems to be connected
but when I want to call some method from Connection class
(like con.getMetaData or con.createStatement) I just get
exception: java.sql.SQLException: Io exception: The Network Adapter
could not establish the connection
When I check listener log file,
there is of course no record about getting connection.
I have Oracle8.0.6, jdk1.2.2, orion1.3.8
My data-source.xml looks like:
data-source
class="com.evermind.sql.ConnectionDataSource"
name="Oracle"
location="jdbc/OracleDS"

and EJB code:

String s = "";
/** THIS PART WORK FINE, BUT IT DOESN'T MAKE CONNECTION AT ALL

InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(dbName);

ResultSet rs = st.executeQuery("SELECT ename FROM emp");
if ( rs.next() )

else

*/
con.close();
return s;

Re: Initial JMSTest++ results, sort of
During all the JMSTest++ tests, both successful and otherwise, Orion didn't crash once. JMSTest++'s JMS compliance tests are necessarily detailed and broad and I find it impressive that while Orion may not have been able to behave appropriately during the tests it never once blinked. So while it didn't support the expected functionality it never once was caught off guard by the test's attempts. Quite an achievement. -- Jason Rimmer [EMAIL PROTECTED]

Re: more question for xml,xsl in orion
I have a XML with data and XSL with the layout information AND JSP Java code in it. How can I tell orion to: 1. Put XML and XSL together and output JSP. 2. Then compile the JSP output to html. I can get XML and XSL to merge together but the JSP compiler will not compiler the JSP output. For example, here is the code. Thanks I am not amazed that the JSP compiler does not get invoked. After all, what orion sees is a request for an XML resource. I presume you would have to somehow generate a second request (via RequestDispatcher.forward()) for the generated JSP page after doing the transformation. This would imply that the XML is never requested directly but through a servlet, which makes 2 calls (include() to invoke the transformation, then forward() to call the JSP). just my 2c Christian

I've tried clustering a web application and it generally seems OK. However, in order to eliminate single points of failure in deployment, I assume that I would have to cluster the EJBs as well. To do that, I've tried running multiple copies of Orion on separate machines, all of them accessing a common set of ejb class files, jsp files, etc from a shared location as well as a common datasource with exclusive-write-access="false" in the orion-ejb-jar.xml files. i'm running some Orion Servers in an "Linux Virtual Server" Cluster (http://www.linuxvirtualserver.org) currently only in my development environment but in short also in production.

RE: Servlet to EJB Principals/Credentials problem! Impossible to solve?!
Hi, Matt There's not that much "seems" to it, nor black magic. :-) I can't tell why EJBs in one scenario see "guest" and in the other they see the proper user, since I don't know how you're logging in and what the test program is. In short, though, there are only so many ways to identify a user to the server in a proper way: 1. jndi.properties, or type it in to the dialog, when using an app client; 2. form-based login (again, a username/password pair); 3. client certs; 4. programmatic using the RoleManager (Orion-specific). When you're using a servlet as your front-end, then, I guess the question is, how are your users logging in? If they are not then you will always see "guest". It sounds like your test program is an app client, the login dialog is popping up, and off you go - no problems. But that's just a guess. So I guess it comes down to details on how your login in the servlet situation is being accomplished, before we can offer any advice.

Impossible to solve?! MY GOAL: I would like to properly log into orion, from a servlet, when requesting EJB calls. I'd like to know which servlet users are hitting which EJBs without explicitly passing the username and password around. This must be possible!! Here is the situation: I'm running Orion 1.3.8 on WINNT 4.00.1381 with JDK-1.2.2_005. Orion is running a servlet that accesses EJBs also run under Orion. I am attempting to pass a username and password back through the use of the SECURITY_PRINCIPAL and SECURITY_CREDENTIAL. When the servlet sets up the call to the EJB and calls it, the PRINCIPAL, when printed out from the EJB always seems to be 'guest'. When I use a test program that calls the EJB through through orion, it seems to get the proper username and password. Why does it not work through the servlet? Why is this happening? One theory brought to my attention was that the two scenarios use different virtual machines. i.e. the first scenario (servlet - ejb) always uses a single virtual machine, while the second (test class - ejb) uses two virtual machines (one for orion, one for the test class). Why would separate virtual machines affect the PRINCIPALS and CREDENTIALS? Any and all help would be appreciated.

Your JDBC driver should be in a file called Classes12.zip or newer, not

Orion Application Classpath
Hi
I am trying to write a jsp page which lists the current
CLASSPATH known to orion. Obviously, if i use
System.getProperty("java.class.path"), i only get "orion.jar" (or
whatever I have in my shell environment when i start orion).
Presumably there is a way of asking Orion to report the classpath,
either for the entire server, or more possibly on a per application
basis. Either is fine for me. I have looked through the Orion API docs,
and i can't see anything obvious that will do what I want.
Can anyone help.
Thanks

Your JDBC driver should be in a file called Classes12.zip or newer, not

How about offering a daily digest version of this list, where the questions and answers are grouped in one daily email?

Re: Very Strange Problem
Hello Juan, Since we haven't seen this behaviour ourselves when load testing, it's hard for us to reproduce it. To be able to give a good guess on what is wrong and if it's in Orion or not we need a test-case. Please submit the suspected bug in bugzilla and attach a test-case so that we can try it out. Regards, Karl Avedal "Juan Lorandi (Chile)" wrote: orion-ejb-jar.zip Here's the deal I'm load-testing my application; Orion's behaving properly and fast while the load doesn't get too high... but when it happens (say, 50 requests/second of dynamic pages), DeadLock's start to ocurr Fine by me, I'm not ready to sacrifice data consistency to elevate the performance, BUT Somehow, Orion, after these problems start to ocurr, doesn't free the DataBase Connections it allocated (as you can see in the application log I'm attaching, first there are DeadLocks, then the server starts to fail waiting for connections).

RE: getServletContext().getRealPath() bug?
Yes we see this too and have since I think 1.3.8.
It compiles but does have a runtime exception, e.g. can't find the method.
So we're doing hacks now using relative paths to figure out where we are.
Basically ever since the experimental 2.3 servlet and jsp stuff it seems to
have disappeared. I didn't know if this was apart of the new spec or not
and they're didn't seem to be a replacement.

I dont see a direct contradiction with the API docs. The example that is
given there prepends the file name with a "/", which also makes more sense
(relative to what should "test.xml" be interpreted?). The implementation of

Re: Supporting classes not getting picked up
I recently had a similar problem with the JavaMail APIs and a custom pop3 provider which would not load wherever I moved the classes (mine were jarred, but that should not make the difference). It turned out that in order to get loaded these classes had to be in orions "master classpath". I ended up with the following alternatives to achieve this: - copy all mail + provider jars into java_home/jre/lib/ext (which you will normally only do with standard java extension APIs) - invoke orion via "java -classpathall jars including mine orion-launcher-class" instead of java -jar orion.jar - modify orion.jars manifest file to include my jars (a hack, but I did it) now, I cannot exactly explain why this is so (and I think it is weird. I would rather have all my application jars in WEB-INF/lib, and with most this does indeed work fine), since I am not a classloader guru. Supposedly there is logic in this, and it is really simple and informative to figure out. However, I have so many things to figure out that more directly pertain to my livelihood... -Original Message- From: Drew Kidder [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Date: Donnerstag, 2.

Limitations of Orion's JNDI implementation?
Greetings, Unless I'm seriously misunderstanding some part of JMS or JNDI, it appears that Orion's JNDI implementation prevents one from using Orion's JMS server across a cluster of Orion EJB containers. Suppose I have two Orion servers, A and B, each running its own set of EJ beans, and I want to use server A as the JMS server for the pair. On server A I can get the appropriate JMS ConnectionFactory through JNDI by fetching the default InitialContext and looking up jms/TopicConnectionFactory. On server B, however, I'd need to get the InitialContext from server A to look up the factory. I haven't been able to figure out how to do this. The RMIInitialContextFactory (default?) apparently ignores the Context.PROVIDER_URL setting, so I always end up with the local InitialContext on B. The ApplicationClientInitialContextFactory, on the other hand, always throws the exception starting with javax.naming.NamingException: META-INF/application-client.xml resource not found at com.evermind.server.ApplicationClientInitialContextFactory.getInitialContext (JAX) although I made a sample application-client.xml and put it in META-INF of my application. Even if this worked, it is my understanding that this InitialContext would be useful only for getting to remote EJBs described in application-client.xml and not anything else on server A, so it doesn't really solve my problem. Is there any way of getting ahold of JMS ConnectionFactories from remote machines? Thanks, Dejan Vucinic [EMAIL PROTECTED]

We are currently working with this exact procedure, and you are correct Manoj, the transformation (XSLT) happens server-side and HTML is just fed to the clients browser.

I notice that there are issues with using it with the latest version of Saxon (5.5.1)... Anyway Orion's implementation of the XSLServlet worked.. but had some limitations with the xsl:param element. If you look in your global-web-application.xml you'll see something like the following : servlet-chaining servlet-name="xsl" mime-type="text/xml" / And also a little later... something like : servlet servlet-namexsl/servlet-name servlet-classcom.evermind.servlet.XSLServlet/servlet-class init-param param-namedefaultContentType/param-name param-valuetext/html/param-value /init-param /servlet This performs servlet chaining... so when your JSP produces an XML document with content type text/xml... the servlet-chaining within Orion captures it and passes it to the XSL servlet... which process it.. produces HTML and displays HTML to the end-user.

Heres the taglib declaration from my web.xml: taglib taglib-uriwww.itsit.de/webcomponents/taglibs/wcf01.tld/taglib-uri taglib-location/META-INF/taglib.tld/taglib-location /taglib -Original Message- From: Aaron Scott-Boddendijk [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Date: Freitag, 3. November 2000 05:54 Subject: Re: Placement of jars for JSP You can place the JAR anywhere - orion will automatically detect it has changed when you recompile / rejar, and it will load the new driver. Just change the location with the taglib-location attribute in web.xml. Ok that's working - can the taglib-location be a folder rather than a jar to test without rebuilding the jar each time... EG place the tag-location refering to the top of our package hierarchy and add a META-INF folder with the relevent taglib/tag info... I've tried it with no luck - is there a way for this to work? -- Aaron Scott-Boddendijk INTAZ Limited +64 7 838 3371 Voice +64 7 838 3372 Fax
Re: choosing database for EJB use?
James Ho wrote: Hi all... Can anyone pls tell me, is there any searching criteria for RDBMS for use with EJB/Orion and why? Is transactions support necessarily for CMPs? No transaction support is not necessary. However if you use a RDBMS without transactions, your EJB application will not support transactions. If you're looking for a db that has transactions and is free, i'd recomend Sybase 11.3. It's free on Linux. sven -- == Sven E. van 't Veer http://www.cachoeiro.net Java Developer [EMAIL PROTECTED] ==
