RE: EJB 2.0 Dependent bidirectional relationships not working
This is something I have found puzzling about Orion's relationship mapping. I suspect it is probably one of those "partially implemented" parts of Orion. It appears that when one-to-many relationships are used, Orion creates and uses a separate relationship table. As far as the EJBs are concerned, everything works just fine, but the table is not a very efficient solution. In fact the "many"-side object table has a column for the mapping field, but my experience has been that this is unused and left as null. FYI, the orion-ejb-jar.xml (and associated documentation) makes for interesting reading. Looks like there are a *lot* of choices for exotic (read: not accounted for in the current EJB spec) mapping types. Karl/Magnus: Is there any way we can find out how complete the implementation of new EJB2.0 features is? I don't know if you folks would rather we enter this kind of stuff in Bugzilla or just leave it alone and wait. Maybe a separate category should be set up for EJB2.0 bugs?

Actualy the windows version of the Sybase database is just as pleasant to work with as SQL server when you use the gui tools. And a bg advantage is that the jdbc driver that is made for the database is very pleasant to work with :), and when you need extra performance you can set the server on a Solaris machine and still use the windows admin tool against it for easy administration. ASE12 allso supports java in the database something that can be quite usefull if you have some routines that is neaded when you import data to make sure things are allright and so on.

Re: Internal Orion requests vs External Requests?
How I've tackled it is by setting a request scope attribute in the filter.
Before the filter is applied, a check is performed to see if this attribute
has been set or not.. if it has then the request is an internal request.
In doFilter()
// Check if filter has been marked as applied
if ( request.getAttribute( "filterapplied" ) != null ) {
// Been done already - jump to next filter
getFilterConfig().getNext().doFilter( request, response );
}
else {
// Hasn't been applied yet, mark it as applied and do
request.setAttribute( "filterapplied", Boolean.TRUE );
// do filter stuff

RE: Orion doesn't interpret Javascript correctly
Yes, the quotes are right. You'll notice that the double quotes surround a
URL argument for the javascript variable (which starts with a leading /),
and that whole thing is enclosed in single quotes as the argument to the
onmouseover call. I believe what you're saying is that I should escape the
inner set of quotes to make them part of the string, right?
I think the problem with this is that javascript doesn't allow embedded
quotes of the same type. Meaning, if you have doubles on the outside, you
have to have singles on the inside, and vice versa. After reading Joe's
response posted here about how Orion rewrites stuff during parsing, I came
to the conclusion that Orion basically forces the outer quotes to be double
quotes, and the inner quotes to be single in order for javascript to be
interpreted right by the browser.
Once I re-ordered my quotes, everything was working fine. IMO, this is the
more logical way to do it anyway, but I s'pose if Tomcat and JRun allow it
to be done the other way, Orion should too. I'll lodge a bug report, and
we'll go from there.
anyhoo, to make a long story short, the problem in my code is fixed now,
and it is operating as it should. Thanks for all the responses!

Subject: Orion doesn't interpret Javascript correctly
All,
I have a fully functional webapp that runs perfectly under
Tomcat (albeit a
little slow). The main menu bar consists of rollovers that
utilize the
onmouseover and onmouseout routines of Javascript. For
example, one of the
tags looks like this:
a href="/news/"
onmouseout='csne_button.src="/images/lv1-off_04.gif"'
onmouseover='csne_button.src="/images/lv1-on_04.gif"'
img src="/images/lv1-off_04.gif" alt="" border=0 height=18
name=csne_button width=117
/a
which, of course basically changes the image when the mouse
pointer crosses
it. Anyway, any time I try to view the pages in any browser that are
served by Orion, I get tons of javascript errors, complaining
about various
aspects of the onmouseout and onmouseover calls, most notably
of which
seems to be a replacement of the single quote delimiters (')
with double
quotes, such as
a href="/news/"
onmouseout="csne_button.src="/images/lv1-off_04.gif""
onmouseover="csne_button.src="/images/lv1-on_04.gif""
img src="/images/lv1-off_04.gif" alt="" border=0 height=18
name=csne_button width=117
/a
which is obviously wrong, and which was obtained by examining
the source of
the returned page. It looks like Orion is not keeping the
single-quote
delimiters properly. Is anyone else having this problem?
Better yet, is
there some solution?

(yet, but can be acomplished especially with CMP, which is what I work with)
yes I also place some BL within Session Beans with a facade pattern...
b) Yes, you may use session beans not only as in a facade pattern, but also
in a Activity-Owner pattern:
Stateful SB - Stateless SB - Entity Beans
TransactionRoot - Facade/BL - Persistence
in this pattern, you have an object which its purpose is transaction
demarcation
remember that transaction demarcation is best done at tier boundaries

Subject: Re: get reference to UserTransaction fails
i was trying to do the same thing, and it sort of makes
sense that you can't control a transaction (UserTransaction)
from outside orion (i.e. the ejb container).
it does raise the question however about how you would
ever maintain any decent level of control over transactions
if entity beans were involved unless you *always*:
1. set the trans-attribute of every entity bean to Mandatory
2. used stateless session beans as a facade to controlling
entity beans.
i've been using stateless session beans for a while and trying
to come up to speed with entity beans. there's probably
something stupid i'm doing but i've been unable to find
a solid way to control database transaction boundaries
unless i use the above pattern (slsb call entity beans).
a) does anyone call entity beans directly from a JSP?
or do you call stateless server beans which wrap entity beans?
b) is it possible to control database transaction boundaries
without wrapping EJB methods calls in a UserTransaction.begin()
and UserTransaction.commit() ?
thanks,
greg

Are your trying to retrieve something from "java:comp" DIRECTLY from code

I have looked (very quickly) at the specs, and I don't think that's
allowed(seems pretty unsafe to me)
Perhaps you can build a session bean that preforms the lookup, then passes
the reference to the client

AW: Interbase datasource??
Hi, i have no datasource for interbase, since i am using only bean managed persistence, but i can tell you some things. The current JDBC driver for Interbase (Interclient) does not support Interbases "dialect 3". This means: you can connect to "dialect 3" databases, but some features will not be availiable. The most important are: LONG INTEGER (64 Bit) database fields does not work. The mapping of a java long to a 32Bit INTEGER or a DOUBLE PRECISION or even a textfield works. For date/time values you should use a TIMESTAMP field in Interbase, which maps perfectly to a java timestamp with the "old" JDBC driver. The other date/time types do not work. All the rest seems to work fine (blobs, etc.) and the performance seems very good (though i did not test really huge databases by now). In the documentation of IB6 (the PDF files, dont remember where is the link) there is a "Getting Started", which describes these migration issues from IB4/5 to 6.

Can't call an EJB from Within another EJB
We have gotten our Orion server(1.3.8) to work with EJBs on a singular level(i.e. we can call EJB A, B or C and it works fine.) But If one of our EJB's tries to call another(i.e. A calls B) A throws a naming exception that it can't find the EJB reference when doing a jndi lookup. Is there a dependency tag or something within one of the XML files that denotes EJB dependencies on one another? I'm sure this is something simple, but it is getting annoying.

RE: Interbase datasource??
Question for you..when I create a database there is something that has a drop-down that says Dialect..and its always selected on 3. Doesn't that mean it supports it? I recall reading that IB6 supports D3 now, so I thought that it did. I have build 308, but I know there is a newer build..maybe that one supports it? Anyways, so it seems like the datasource should look like so: ?xml version="1.0"? !DOCTYPE database-schema PUBLIC "-//Evermind//- Database schema" "http://www.orionserver.com/dtds/database-schemas.dtd" database-schema name="Interbase" not-null="not null" null="" primary-key="primary key" type-mapping type="java.lang.String" name="varchar (255)" / type-mapping type="int" name="int" / type-mapping type="long" name="int" / type-mapping type="float" name="float" / type-mapping type="double" name="double" / type-mapping type="byte" name="byte" / type-mapping type="char" name="char" / type-mapping type="short" name="short" / type-mapping type="boolean" name="boolean" / type-mapping type="java.util.Date" name="timestamp" / disallowed-field name="password" / disallowed-field name="username" / disallowed-field name="date" / /database-schema Does that seem like it would work? I am not sure about the int, long, float, double, byte, char, short and boolean. I thought someone posted a schema before that they were using, and I can't seem to find it anywhere in my archives of emails. Its pissing me off because I can't even mess around with entity beans because of this. Incidentally, do you know how I would get Orion to use this schema?

Doesn't that mean it supports it? I recall reading that IB6 supports D3 now, so I thought that it did. I have build 308, but I know there is a newer build..maybe that one supports it? Well, I can't help you on the rest of the message. (I haven't gotten around to getting it all set up yet grin ) I can help you on this. Although IB6 has a Dialect 3, the Interclient JDBC drivers only support Dialect 1 still. [This will change for Interclient 2.0]. So you have to use Dialect one for databases when running JDBC drivers still. HTH! -Mike

Re: Ok. I feel dumb. Data Sources and MS SQL.
we use a driver from http://www.inetsoftware.de/ for sql server. there's an evaluation version if you want to give it a go - Original Message - From: "Kimberley Scott" [EMAIL PROTECTED] To: "Orion-Interest" [EMAIL PROTECTED] Sent: Wednesday, October 25, 2000 11:15 AM Subject: Ok. I feel dumb. Data Sources and MS SQL. Hiya, Feeling real stupid here. I'm examining data sources and getting totally confused. Maybe I'm just burnt out. Haven't had a holiday in five years. Sigh. Back to business. We're *forced* to use Microsoft SQL 7 and Win2K. How do I set up the datasource xml file to handle this? I can't seem to find anything on this in the email lists on in the docs. The only drivers I have are the ODBC bridges (The invisible hidden MS one and the standard Sun one) and I'm not paying for a Type IV driver at the outrageous prices I've been presented with from BEA and the like. Has anyone done this before or can point me in the right direction? A tired developer who's feeling very old and dim...

RE: Orion as NT4 Service
We are using JNT, a free service runner for java applications that properly handles the log-off command. I forget the url, but if you do a search at excite or something, I am sure you will find it. We were using run_as_service, or srvany, neither of which properly worked. -Original Message- From: Todd Renner [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 25, 2000 6:48 AM To: Orion-Interest Subject: Orion as NT4 Service Hi, We've setup orion (1.2.9) to be an NT service as specified at orionsupport.com. But whenever we log off the machine the server stops with no errors. I recall some discussion on this awhile ago, but all I could find in the archives pertained to Unix.We've tried several different scenarios, diff. users, reboot and not logging in etc. but with no success. Anybody have some suggestions as to what to try? Were using sunjdk1.3, hotspot server, nt40.Thanks. Todd Renner [EMAIL PROTECTED]
