threads, initialcontext and login
I have created a small client software which connects to EJB-services
running on Orion, of course.
My program has a GUI "launcher" from which users can start client
objects. These objects use InitialContext to deliver user/password information
to EJB-services.
Everything works fine until user gives wrong username/passwd ...
Now since InitialContext is permanent threre is no way to change it
anymore unless user restarts the program, which is lame.
Code:
Runtime r = Runtime.getRuntime();
Process p = r.exec(" java myClass ");
Works but is awfully slow. Any insights?

RE: ejb deployment problem
That is because in JBuilder you deploy your beans to IAS. You specify a Datasource name. You have to specify a different DataSourc name for Orion too. That can not be done inside of JBuilder. For Orion: 1 Open Orion-Home-Dir/application-deployments/Your-App-Name/orion-application.x ml 2 Add an attribute default-data-source="your-data-source" to the element orion-application 3 Remove any ejb deployment descriptors below this directory (orion-ejb-jar. xml) 4 Start Orion. Orion should now deploy your ejbs again. 5 Check in an orion-ejb-jar.xml file in any entity-deployment element for an attribute data-source. Hopefully it should now use your Data Source. /korre -Original Message- From: ahfei To: Orion-Interest Sent: 2001-01-07 18:00 Subject: ejb deployment problem hello, i'm developing ejb using jbuilder4.The EJBs work well in inprise app server. when i deploy it to orion,it works too. but i found the datasource that i specified doesn't be used,orion uses a default datasource (HSQL) service my EJBs.WHY ? can somebody help me? thanks in advance. ahfei [EMAIL PROTECTED]
Re: Automatic generation of virtual directory tag in the orion-web.xml doc ?
Ok. sorry. I am using an old version of orion I am using the version 1.0.3 ... I tried with orion-web.xml in the war and it didn't work.

Hi all, I am trying to find out how the generation of the orion-web.xml document is carried out. I need indeed to use virtual directory tags to point onto my resource shared directories (image,scripts, ). I would have appreciated that the following tag, virtual-directory real-path="/usr/local/realpath" virtual-path="/the/webdir" / would have been created automatically by orion appserver from a tag located somewhere in the ear orwar deployment xml files ... Actually, it's a little bit boring to rewrite several times this tag ... above all when you have 10 virtual directories for each of your sites (I mean your war app). If any of you has a way to handle this "problem", I am very very very interested to learn his/her trick. I mean, ... if any of you know how to insert in a .ear the right info so that orion appserver generates the good orion-web.xml file with my "virtual directory" tags ... I am obviously fully interested in his/her method. Any info is greatly appreciated. Many thanks.Regards Jean-Guillaume LALANNE Jean-Guillaume COMING [EMAIL PROTECTED]
Offtopic: Any opensource database query tools?
I have a stateless session bean which does all the keyword searching for my application. Right now the searching is quite simple, it "ANDs" all the keywords and does a 'like %keyword%' clause on them. I was wondering if there are any open source objects to assist in smarter searching, such as : "DVD Player" -Sony (they typical stuff you see on search engines, etc) ? Thanks.
create doesn't return my exception
Ever since I updated from Orion 1.2.9 if my ejbCreate fails it always throws
NullPointerException, PrimaryKey was null. It used to return the exception
that I would throw. Note this happens in Orion 1.3.8, 1.4.0 and 1.4.4
For example:
public MyPK ejbCreate(...)
throws CreateException
{
MyPK myPrimaryKey = null;
// do the insert
try
{
myPrimaryKey = insertUpdate(...);
}
catch (Exception ex)
{
throw new CreateException("ejbCreate: " + ex.getMessage());
}
return myPrimaryKey;
}
Has anyone else seen this?
Thanks,

RE: ResultSet Caching
I would just like to clarify that I mean to use HttpSession to store your temporary data rather than Session bean. A usual technique I have been using is to load a whole bunch of kind-of static data and serialize it into Xml. Hence the XML data can be stored in the HttpSession safely or even persistently since my XML data is just a string. Of course a more sophisticated solution can also be built on top of this generic architecture like cache time-out etc. Hope this help Conrad -Original Message- From: Neal Kaiser [mailto:[EMAIL PROTECTED]] Sent: Friday, January 05, 2001 4:31 PM To: Orion-Interest Subject: RE: ResultSet Caching Right, I definitely wouldn't use an entity bean for list/search functionality. Way too much overhead. Stateless session beans is the way to go, but I don't think throwing in large variable sets into a session is a good solution either. Bloated sessions don't perform well either. Some app servers provide a caching solution, like Gemstone I believe, and I was just wondering if Orion had something similar.

RE: Complex O/R and EJB 2.0 CMP
From: Darren Pamatat [mailto:[EMAIL PROTECTED]] I like the layout of the complex-or example more so than the orion-cmp primer, because it is not required to jar it up, and classes can just be recompiled, and run (if only I could run something against it). Also, what is the difference in the EJB 2.0 CMP and orion proprietary CMP. You're asking about "CMR", container managed relationships, not CMP. Orion was apparently providing CMR services before there was an EJB2.0, and the information is maintained in the orion-ejb-jar.xml file. EJB2.0 allows you to define relationships in the J2EE-standard ejb-jar.xml file, which Orion then converts to the appropriate definitions in orion-ejb-jar.xml upon deployment. So there aren't two different types of CMR; there are just two layers. Take a look at the documentation for orion-ejb-jar.xml; there is a lot you (supposedly) can do that is not yet supported by EJB2.0 (like Map and List types). Jeff
