Please Help Me, How to congfig Postgres DataSours on Orion?
Dear, I used Orion 1.3.8, Postgres 6.5,andits JDBC Driver jdbc6.5-1.2.jar.

I have a number of Session beans deployed to Orion (1.4.4 level), and everything works great when communicating from an application client (JSPs and servlets running Apache Tomcat) to the Orion server. Now I want to add some EJB to EJB communication, with one EJB obtaining the home and remote interfaces of another EJB and executing methods on that remote interface. When I attempt to lookup my bean using the JNDI context, I get an exception being thrown that says that it can't find the JNDI lookup name in the Application Client. I assume that Orion is not finding the application_client.xml file within its own environment. What are others doing to rectify this situation? I assume that EJB to EJB communication is **very common**, as most people are using Session bean fascades around their Entity beans. An example of this sort of functionality and the steps needed to configure it should be available through Orion or orionsupport.com, but I could not find anything. Thanks in advance.

CMP-finder with another entity as argument?

Something like: public Collection findByProject(Project project) throws RemoteException, FinderException; Now how do I modify the finder-method query="???" partial="false" to accomplish this? My impression is that it is not possible. Ok so what do I have to do? Write a finder like this instead? public Collection findByProject(long projID) throws RemoteException, FinderException; and create a finder-method like this: select ... ... from project,person where project.project_id=$1 and ...

Problems with Orion load balancer.
Dear All, I'm having problems with load-balancing a single island of two orion appservers. I have followed the instructions from the clustering 'howto' document, and I've made changes to the relevant XML files. Note, I made the changes to the default web app files, rather than to the XML files specific to my app. From the documentation I expect the changes to therefore impact *all* apps, and that I should experience the desired clustering and load balancing for my app. Using the Microsoft Web App Stress Tool, running 100 threads which continually request a single page from the clustered app via the load balancer, things seem to work fine for the first minute or so, despite the fact that the balancer 'drops' servers periodically but then manages to re-discover them. The performance meter for the servers in the app cluster show that both machines are working at close to full capacity during this brief period. At some point after that first minute or so, the load balancer will typically drop one of the servers, re-discover it, add it back into the island, but that server will thereafter be unloaded - the performance meter registers 0% load. Note that this is despite the fact that the other server - still alive, is working flat out at 100%. Has anyone experienced this before ? I can't find anything in the archive. I'm especially perplexed since a lot of other people claim to have load-balancing and clustering working fine - after working from the same 'howto' as me. I would really appreciate help on this.

SV: Access EJB's from a standalone client.
I'm sorry I forget to tell you that you also have to add namespace access in
the application-deployments/yourAppName/orion-application.xml file too
(i.e on the server side only). Like this (in my case)
namespace-access
read-access
namespace-resource root=""
security-role-mapping
name="lt;jndi-user-rolegt;"
group name="administrators" /
group name="users" /
/security-role-mapping
/namespace-resource
/read-access
write-access
namespace-resource root=""
security-role-mapping
name="lt;jndi-user-rolegt;"
group name="administrators" /
group name="users" /
/security-role-mapping
/namespace-resource
/write-access
/namespace-access
Also in $ORION/config/principals.xml I have set up normal and admin users
and their passwords. It is this information that is put into the
jndi.properties file on the client side I referred to in my previous post.

Does anybody know what could cause a javax.naming.NameNotFoundException:
my
bean name not found? I think my .xml files are fine, and I think this
used
to work!
We've got the same problem - it seems Orion 1.4.4 can't decide whether to
make EJB home interfaces available at "java:comp/env/ejb-name" or just
"ejb-name". We've replaced all our lookup code with something like this:
Object ref = null;
try{
ref = jndiContext.lookup("java:comp/env/ejb/WhateverEJB");
} catch(NamingException ne) {
System.err.println("Failed to find WhateverEJB attempting again
using non-standard mapping");
ref = jndiContext.lookup("WhateverEJB");
}
WhateverHome home = (WhateverHome)PortableRemoteObject.narrow(ref,
WhateverHome.class);
This at least lets the app function. Sometimes the first lookup works,
sometimes not. If and when we see a pattern that implies sort sort of reason
for this strange behaviour, I'll report it to the list.

Don't update to 1.4.4 if you are using the DataSourceUserManager and want to store your groups/roles in a database. I spent days trying to get it to work before I read that 1.4.4 broke the DataSourceUserManager piece. The DataSourceUserManager works in 1.4.4, but only if you are storing your group permissions in principals.xml I deleted 1.4.4 and then put 1.3.8 back on and everything instantly worked.

Stress orion = servlet engine's LOOKUP hungs arround 200 users !
A few days ago we've post a question about "servlet engine hung arround 200 users". We have investigate. In fact the servlet engine (in a separate VM from the ejb server, see config below) is waiting about many simultaneous multi-threaded call to InitialContext.lookup(on session bean) when more than 200 simultaneous users are connected ! I precise that each threads manipulate a different InitialContext instance (so don't need synchronize...). And jprobe threadanalyser doesn't detect any deadlock on the webServer nor on the ejbServer... The servlet engine is hung in 60 to 150 simultaneous lookup() that never return. The problem appear when the web server do remote rmi call for all ejb (see config below). == Is anyone have already seen this kind of problem in lookup ? What's wrong on the rmi port or rmi registry ?? thank's for any help, Stan. PS: 1. We stress our appli with WebLoad (throw http request from 4 different client host), on NT with following config: - WebServer: orion1.3.8+jdk1.3 on a PIII 700MHz - 512 Mo RAM and all ejb call are remote call to following ejb server. with orion-application.xml: orion-application ejb-module remote="true" / // for all ejb-module /orion-application and rmi.xml: rmi-server server host="EjbServer" port="23791" .../ /rmi-server - EjbServer: orion1.3.8+jdk1.3 on a PIII 500MHz - 256 Mo RAM with rmi.xml: rmi-server port="23791" /rmi-server - DataBase: oracle8i ... 2. if we stress the application without remote call for the ejb's everything is OK for more than 500 simultaneous users !! - Web+EjbServer: orion1.3.8+jdk1.3 on a PIII 700MHz - 512 Mo RAM with orion-application.xml: orion-application ejb-module remote="false" / // for all ejb-module /orion-application and rmi.xml: rmi-server /rmi-server - DataBase: oracle8i ...
Re: Report Printing Tool??
Hi Seung We got our reporting tool from Elixir( www.elixirtech.com ). Looks good and is inexpensive and royalty free. Most importantly for us, it can do applet-based reporting. You might want to check it out - free non-timelimited eval version with crippled printing support is available... Regards Satish Seung Bang wrote: Hello, We are now almost finished with EJB, JSP and Servlet stuff. All we gotta do is print. As you know, web browsers don't print well-formantted reports. I was thinking of using retepPDF which was a great library for PDF file generation, but it lacked the function of laying out images on report forms. I wish there were CrystalReport for Java. I checked out the Seagate's site and they seemed to support Windows only. Any suggestion?? Any Idea? Maybe we can make a nice applet to do that. Any other idea??? ;-) Thanks a million. Simon
FreeBSD port for Orion
Hi to all fellow FreeBSD users on o-i, At the moment I am working on a port for Orion, and it is in beta stage. If anyone would like to comment on it, just poke it, and let me know. There's a tgz available at either of the following locations: * http://www.znerd.demon.nl/orion-port.tgz * http://www.jollem.com/~ernst/orion-port.tgz Or you can browse the files from either of these locations: * http://www.znerd.demon.nl/orion-port/ * http://www.jollem.com/~ernst/orion-port/ Any and all comments are welcome! To test this port thorougly, follow the procedure described at: * http://www.freebsd.org/porters-handbook/porting-testing.html Note that I tested this port with portlint, available from the devel/portlint port. Note for non-FreeBSD users: This will enable FreeBSD users to install and deinstall Orion in a very easy way. To install: # cd /usr/ports/java/orion/ make install And to deinstall: # cd /usr/ports/java/orion make deinstall Ernst
Re: FreeBSD port for Orion
Are you looking for any help on this port? I've been working on an internal copy and have yet to show anyone outside of my office.

Re: Sharing Thoughts ...
Hi,
At last, I have found the appropriate place for tag libraries. Here is a
"Hello" tag which I have tried. What I found useful with this approach is
that it doesn't need to create a jar file for the tags for development
purposes. Moreover while creating a .war file it's much easier to pack the
entire web directory and we need not do anything extra.
If there is any other method which is more simpler or easier to maintain for
both development as well as packaging, please do let me know.
Step 1
--
Place all your tag handler source files in a package under WEB-INF\classes
directory. For example, I have used the following,
$ORION\application\web\WEB-INF\classes\tagext\Hello.java
***
package tagext ;
import java.io.* ;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
public class Hello extends TagSupport {
public int doStartTag() throws JspException {
return EVAL_BODY_INCLUDE ;
}
public int doEndTag() throws JspException {
try {
pageContext.getOut().write( "Hellobr" ) ;
} catch ( IOException e ) {
throw new JspTagException( "JSP IOException" ) ;
}
return EVAL_PAGE ;
}
}
Step 2
--
Define TLD under WEB-INF\tlds directory. For example,
$ORION\application\web\WEB-INF\tlds\taglib.tld
taglib
tlibversion1.0/tlibversion
jspversion1.1/jspversion
shortnamelearn/shortname
infoLearn JSP Custom tags/info
tag
namehello/name
tagclasstagext.Hello/tagclass
bodycontentJSP/bodycontent
infoSimple Tag Example/info
/tag
/taglib
Step 3
--
Referring a tag from JSP file. Example.
%@ taglib uri="WEB-INF/tlds/taglib.tld" prefix="learn" %
h3A Simple tag/h3
learn:hello /
hr

Looks like a great idea. You place your tag library jars in the
web/WEB-INF/lib directory.
(Or at least I do).

Hi,
I just wanted to share my thoughts regarding Orion to you all.
I am still a newbie with Orion Server. After reading thro' the
documentation, looking for information here there, I have found the
following to be useful for "Orion Freshers" who want to kickstart their
application development.
Directory Structure for a new J2EE application
--
$ORION\application\ - Application root
$ORION\application\META-INF\application.xml - Descriptor for
Application
$ORION\application\ejb\ - Root dir for EJB's
$ORION\application\ejb\META-INF\ejb-jar.xml - Descriptor for EJB's
$ORION\application\web\ - Root dir for Web
contents
$ORION\application\web\WEB-INF\web.xml - Descriptor for
Web contents
$ORION\application\web\WEB-INF\classes\ - Servlet dir
$ORION\application\web\WEB-INF\lib\ - lib dir
where $ORION is the home directory for Orion.
$ORION\application\META-INF\application.xml
-
application
display-name../display-name

ejbejb/ejb
/module

ejb-ref-nameejb/EJB Name/ejb-ref-name
ejb-ref-typeEntity|Session/ejb-ref-type
homeHome Name/home
remoteRemote Name/remote
/ejb-ref
/web-app
Remember to add the following
-
application name="application" path="../application" / in
$ORION\config\server.xml
web-app application="application" name="web"
root="/application" / in
$ORION\config\default-web-site.xml
Now start orion and just point http://servername[:port]/application
That's it.
For combining everything into an .ear file, it's as simple as changing
ejbejb/ejb to ejbejb.jar/ejb and web-uriweb/web-uri to
web-uriweb.war/web-uri in
$ORION\application\META-INF\application.xml
Is there any other better method. If yes, please do let me know. In
the
meantime, I will start digging up Orion. Also I wanted to know where to
place my tag libraries, assuming I am following the above directory
structure.
With regards
