JSP extends directive - has anybody tried it?
Hello List, We are currently trying to port our complete JSP (1.0-style) application to Orion. For historical reasons our application uses the JSP extends directive, for example: %@ page extends="com.finatec.services.servlet.ISecureServlet" % We have converted our ISecureServlet class so that it itself extends the Orion implementation class com.evermind.server.http.EvermindHttpJspPage. We have previously ported our application to Resin, which also has a JSP 1.1 engine, using the same technique. However, when we now access the containing JSP page it compiles but fails during processing with the error "Superclass of the JSP page does not implement HttpJspPage, invalid extends attribute" We've traced the problem down to the point (in dn.class) where Orion checks to see (we believe) whether the generated JSP Servlet class is assignable (via the Class.isAssignableFrom method) from the class that we are extending, namely ISecureServlet. The classes are not assignable, hence the error message. With this in mind, I have two questions: 1. Is the assignment check the right way around? Shouldn't we instead check to see if ISecureServlet is assignable from our generated servlet? 2. Otherwise, has anybody successfully used the extends directive? If so, what class did you inherit, and do you have any other tips that might help us out?

RE: Solaris
We had this kind of behaviour until we upgraded to the absolute latest JDK for our Solaris (which is 2.8). I think it was the 1_2_2_05 JDK. I think you said you had a slightly older version of Solaris, so you'll have some JDK patching to do if you upgrade, but it may do the trick.

Remote Restart
I am using Orion 1.0. I remotely modified the data-sources.xml file. Then I remotely issued a restart command as follows: java -jar admin.jar ormi://myHost admin admin -restart Problem is, the new datasource that I added is not recognized by my jsp pages. Thus, it seems that the restart didn't work. Any suggestions? Is thus a bug? Dave

Isolation level of transactions
Hi, i have an application, in which multiple clients will concurrently modify the same entity bean instances, with which i experienced heavy problems. The database backend sometimes throws exceptions as if there were concurrent locks on the same resources. I tried to experiment with the isolation level settings in the orion-ejb-jar.xml, but this seems to have no effect. As far as i have understood the EJB concept, an entity bean could be considered as a sort of "serialization bottleneck" for concurrent transactions. There is only one instance which sequentially satisfies the clients requests (and if the isolation level is set to "repeatable_read", it should "serialize" the requests on a per transaction basis, i assume, ie do not let anyone else read or write the bean until the transaction has finished). Orion instead seems to run the ejbXXX functions in concurrent threads simultanously and the isolation level setting does not seem to have any effect. Could someone please clearify how it is assumed to be following the spec (the above is only my interpretation) and how it is implemented in orion (and which transaction related settings work and which not)? In this context i'd like to mention the "max-tx-retries" setting, which either does not work or i do not know for which type of exception it does work. The transaction behaviour is very important for me, since i don't use EJB as another (read) access type to existing databases, but in a very dynamic, heavily changing data environment with many concurrent transactions. Thanx in advance for any reply, Jens Stutte P.S.: Last week i posted a bug with the subject "Different home class type returned by local than by remote client". Are there any news on this issue?

FEDERATION !!!
Hi again, In ORION/CONFIG/RMI.XML What is the use of the server tag ? server host="the.remote.server.com" password="123" port="23791" username="admin" / Specifies a remote (point to point) RMI-server to communicate with. host - Hostname of the remote server. password - The password to log in with. port - Port of the remote server, default is 23791. username - The username to log in with. I do not understand what it is aimed for. What I want is to create a security domain between two Orion servers. When EJB in Orion A connects to EJB in Orion B, 1) Orion B does not know this user and 2) Tries to find it in Orion A. 3) and then authenticates. Can I do this with Orion ? Regards, Pedro

Applet and Orion. Please help!
Hallo!
This question is perhaps not orion specific, but bear with me. I am a bit
desperate.
This is the case:
I have an application running as an applet inside jave-plugin version 1.3. I
have signed the .jar files which are used with a self made certificate and
jarsigner -verify says it's good. Applet and orion is on the same computer
and addressed through the same dns name. I also have GIS-engine running on
the same machin, which is also addressed, from the applet and works through
sockets. It works fine from the applet. And if I run the program in like
java -jar app.jar it works.
Now to the problem, when I try to make a connection through to the naming
server in orion from the applet I get a security failure.
This is what the java console gives me:
java.security.AccessControlException: access denied

The source code which gives this is:
// Put this applet instance into the environment
Hashtable env = new Hashtable();
env.put(Context.APPLET, this);
System.out.println("pip");
Context ctx = new InitialContext(env);
System.out.println("pip");
// List objects
NamingEnumeration enum = ctx.list("");
System.out.println("pip");
while (enum.hasMore())
{
System.out.println(enum.next());
}
System.out.println("pip");
ActivityHome home = (ActivityHome)
ctx.lookup("ejb/pakka/Activity");
Applet start code is::
jsp:param name="java.naming.factory.initial"
value="com.evermind.server.ApplicationClientInitialContextFactory" /
jsp:param name="java.naming.provider.url"
value="ormi://localhost/appit" /
jsp:param name="java.naming.security.principal"
value="appit" /
jsp:param name="java.naming.security.credentials"
value="appit00" /
This gives in html:
PARAM NAME="java.naming.factory.initial"
VALUE="com.evermind.server.ApplicationClientInitialContextFactory"
PARAM NAME="java.naming.provider.url"
VALUE="ormi://localhost/appit"
PARAM NAME="java.naming.security.principal" VALUE="appit"
PARAM NAME="java.naming.security.credentials"
VALUE="appit00"
Everything looks fine except from that dammed exception. And I have
of'course made an application-client.xml that refers to the ejb session
beans in question. Since everything works standalone I am lost. Since I
signed the applet too I am really lost.
I would be most grateful for any help...

Torgeir Lerkerød

Re: Error trying to deploy web application
Thank you very much. That does help. It ends up I had META_INF instead of META-INF so it wasn't working. What are the GUI tools? Are they documented anywhere? How do I use them?

Your application.xml file would specify either a directory or a jarfile inside the "/home/joel/app/orion/applications/test" application directory, identifying it with the module web.../web /module tag. As far as the file structure of a web app (the web component) goes, this is spelled out in the Servlet spec. In brief, the directory containing everything pertaining to your web component contains content (HTML, JSP, image) files and a "WEB-INF" directory containing a "web.xml" deployment descriptor _and_ a "classes" folder, which contains servlet and JavaBean classes. WEB-INF may also contain a lib directory if you're including taglib jars. Hope this helps. I recommend reading the J2EE, EJB and Servlet specs for the file structure information. The Orion docs include all of these PDFs. Arved Sandstrom P.S. Orion includes GUI tools for doing all of this. I have found that GUI tools for _any_ app server are best used _after_ an individual is able to assemble an application manually, including writing the descriptors by hand. This just results in more knowledgeable team members.
Complex Primary Key problem
I have a Primary Key class defined for my entity bean. The table only has one primary key, and the key class only has one attribute. When I deploy and attempt to invoke 'findByPrimaryKey(pk)', I get an abstractMethodError. Deploying an entity bean with a table of two primary keys and a class that has the two attributes, it works fine. Same for deploying a bean with a table that has one primary key, and using an equivalent java object as the primary key(and no seperate class). Does Orion have a 'rule' that you cannot have a primary key class that has only one attribute? Does it mandate that you simply use the equivalent java object type of the primary key like BigDecimal? This is a huge showstopper for us, so any feedback would be great. Thanks!

RE: Sessions And SSL
Sure, often with ISPs you get secure server access, and you can either use their certificate, or purchase your own from Verisign, etc. So, if you are using a shared certificate, even though your non-secure domain could be http://www.yourdomain.com, your secure domain would be https://www.myisp.com/~yourdomain/. Thus, you can't share cookies between your HTTP and HTTPS by default.
