AW: java.lang.OutOfMemoryError
Just because there where several different (and some misleading) answers: The problem described is solved with the newest orion version (i don't rember, if since 1.4.5, .6 or .7, i am using .7). As Kevin described, you must set the max-instances attribute for _each_ entity bean that is supposed to have much instances. Unfortunately, there is no overall server setting like "If the VM uses X MB of memory, kick some least used entity beans out of the cache". Therefore one has to play around with the settings to find a combination, that fits the needs (note, that every time you add an entity bean type, the possible maximum overall amount of memory increases, too, which sadly, sadly cannot be said of the physical memory in your machine...). BTW: code like creating 100.000 _entity_ beans in a loop is generally supposed to work - entity beans must be only deleted, if you want to delete their persistence (the database entry). Instead it would be no good coding practice, to create tons of _session_ beans without deleting them after use. Best regards, Jens Stutte -Ursprngliche Nachricht- Von: Kevin A.

Mrz 2001 17:25 An: Orion-Interest Cc: [EMAIL PROTECTED] Betreff: RE: java.lang.OutOfMemoryError We found we could force passivation in the later orion builds - not sure exactly whch builds it works in, but its OK in 1.4.7. Create a directory called orion in the root of your ejb jar (i.e. as a sibling of your META-INF directory). In the orion folder, create a file orion-ejb-jar.xml (The easy way is to copy the one that was auto created on a previous deployment - look in the $ORION_ROOT\application-deployments and the correct sub-folder.) Edit the file so that there is a max-instances="100" attribute on each of the entity-deployment entities. Delete the previous deployment directory (otherwise the new file will not be copied over), and repackage/deploy. Seems to work for us.

Change your server.xml file to include something like.. application name="orionTest" path="file://C:/work/oriontest.ear" / Start orion the normal way.. java -jar orion.jar Well, I don't know how to execute an external client that reference classes inside a jar that is inside an ear, but the following works fine..

Re: ejb in other application ?
Hi Eddi, yesterday i read in the docu to server.xml: application [...] parent="anotherApplication" [...] / [...] parent - Optional 'parent' application, the default is the global application. Children see the namespace of it's parent application. This is used in order to share services such as EJBs among multiple applications. but i don't try it myself. perhaps it helps klaus ps: if you manage it to work, please drop me a mail.

RE: Paged search results
"application" is an instance of javax.servlet.ServletContext which is available in JSPs; this object has application scope and therefore is a good place to store objects [with: application.setAttribute(name, object) ] which you want to make available to servlets/JSPs throughout an application. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Andy Chapman Sent: Wednesday, March 28, 2001 2:39 AM To: Orion-Interest Subject: Re: Paged search results Johan, Please enlighten me - what is the application object that you refer to?

Thanks, Andy - Original Message - From: "Johan Fredriksson" [EMAIL PROTECTED] To: "Orion-Interest" [EMAIL PROTECTED] Sent: Wednesday, March 28, 2001 8:17 AM Subject: Re: Paged search results My first thought is that a cache should not be stored in a session, since that would only be available in that session and "cannot" be shared... Better to store a searchresult in the application object ( if the result is static and is the same for all users). If the searchresult is specific to a certain user, then you could store it in a session. For multibrowser usage, there will be separate sessions for those. There is probably a way to get them to use the same session, but I haven't tried this. In this case I suggest a hashtable in the application object and an id string ( key in hashtable ) in the session. Hope this at least gives you a couple of ideas on how to get started. regards Johan
RE: Who's wrong?
according to the jsp spec, there should be no ';' at the end afaik .. jrun is in violation imo. from: http://java.sun.com/products/jsp/tags/syntaxref.fm4.html When you use the Java language for scripting, remember these points: . You cannot use a semicolon to end an expression (however, the same expression within scriptlet tags requires the semicolon; see Scriptlet). .

RE: Who's wrong?
There is another way to resolve problems like this: Look at the technical specification instead of blindly trusting 3rd parties! From the JSP 1.1 Specification, look at Chapter 2 "Standard Syntax and Semantics", or more specifically at Section 2.10.3 "Expressions". You will get a nice paragraph description and an example: %= (new java.util.Date()).toLocaleString() % as well as Syntax: %= expression % -jason -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Kemp Randy-W18971 Sent: Wednesday, March 28, 2001 10:07 AM To: Orion-Interest Subject: RE: Who's wrong?

Re: Paged search results
I guess my confusion comes into a lack of terminology and understanding of how to approach this problem. What we would like to do is be able to perform a search on the DB, but only show the user 10 of the results at a time. Initially we have thought that sessions might be the key to this, but then wondered what would happen if the user had more than one browser window open, clearly they would be clobbering each others cached search results, no? So we have also thought about perhaps using another table to store the results from each search performed associated with each browser window through attempting to add a unique value to a query string which will also be the PK in the table of search results. This way we can move the current record pointer forward and backwards at will and allow for people having more than one browser window open while doing searches. Do these concerns/strategies sound sane? If not, maybe it is a reflection of my own state of mind (i.e. insane :) Many thanks to those that have currently contributed to this discussion. -- Holden Glova, [EMAIL PROTECTED] Software Engineer Alchemy Group Limited Level 6 Royal Sun Alliance Bldg PO Box 2386 Christchurch New Zealand Phone: +64 3 962-0382 Fax: +64 3 962-0388

Hi, well I think that you can use many ways to approach your objetive. One can be: Use a DB that allows "limit", and move forward and backwards with this function (I tested it in mySQL and it works great!), as you can tell "from", and "how many" results to show... It's quite easy... Another way can be using a Session Bean, controlling all the searches, and then you can use a Collection, List, everything you want. The SessionBean has to be Stateful for using it in many searches; you can regroup by "search" words, so you can have one Collection for each search, and paginate in each, individually... So we have also thought about perhaps using another table to store the results from each search performed associated with each browser window through attempting to add a unique value to a query string which will also be the PK in the table of search results. This way we can move the current record pointer forward and backwards at will and allow for people having more than one browser window open while doing searches. Are you talking about BMP or CMP?
