Re: HINT: One possible way to cure an internal error on deployment
I've done something kind of similar. I found through experimentation that the Orion-generated file orion-web.xml, which lives in the app-specific subdirectories beneath application-deployments, had gotten stale -- out of sync with my deployment descriptors. When you shutdown Orion and blow away that file, Orion generates a new one with correct values. Similar to your experience, that stopped the 500 Internal Errors. Just noting this so you can experiment with it in future. Hope this helps! --Mark Jim Archer [EMAIL PROTECTED] Sent by: [EMAIL PROTECTED] 10/23/00 09:11 PM Please respond to Orion-Interest To:Orion-Interest [EMAIL PROTECTED] cc: Subject:HINT: One possible way to cure an internal error on deployment Hi All... I just thought I would put this out in case anyone finds it usefull to tuck away for future use. For about an hour now, I have been getting an Internal error on deployment. The error complained that the persistence type was not set for one of my fields in an EB that participated in an EJB 2.0 CMP relationship. I don't know what made me do it, but I went over to application-deploymnts and blew away the entire application folder. Then I started Orion and the app deployed like a champ. If I could reproduce this, I would bugzilla it, but I can't, so I'm just offering this hint. Jim

On Yesterday, Mark ([EMAIL PROTECTED]) wrote:
Fixed it! Yay!
Gary, I tried it again per the suggestion you forwarded from support,
but this time by removing the resource-ref from my web.xml and coding
my Java as you noted: "jdbc/etc". Also fixed the startup problem by
removing a transparently stupid syntax error from data-sources.xml.
In case anybody else has been following this thread, here's the working
data-source and a code fragment:
data-source
name="Oracle data source"
class="com.evermind.sql.ConnectionDataSource"
location="jdbc/OracleDS"
pooled-location="jdbc/OraclePooledDS"
xa-location="jdbc/xa/OracleXADS"
ejb-location="jdbc/OracleEJBDS"

connection-driver="oracle.jdbc.driver.OracleDriver"
username="foo"
password="bar"
schema="database-schemas/oracle.xml"
/
InitialContext cxt = new InitialContext();
// WRONG: DataSource ds = (DataSource)
cxt.lookup("java:comp/env/OracleDS");
DataSource ds = (DataSource) cxt.lookup("jdbc/OracleEJBDS"); // RIGHT
Connection c = ds.getConnection();
So the moral of the story seems to be, don't use the syntax
"java:comp/env/myDS"; rather, use "jdbc/myDS".
Note I've substituted "OracleEJBDS" per the note from support which Gary
included earlier in the thread.
Finally -- 'cause I'm personally done with this thread for a while, ;-)
-- if any of the Evermind folks are taking note, I'd very much like to
be able to choose to use networked LDAP for objects such as
DataSources. Please consider this an enhancement suggestion.

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?

As I mentioned in an earlier message, I have some working example code that has an EJB 2.0 CMP entity bean working with both one-to-one and one-to-many unidirectional relationships. Next, I want to change the one-to-many relationship to be bidirectional. I expected this to be a simple change, but it didn't work out that way. I see that the ATM example does not include a dependent object with a bidirectional relationship, so I'm wondering if thie feature is known to work or not. If no one here has used this feature successfully, I'll add a bug report to bugzilla, but I wanted to make sure I did everything right first. To make my changes, I added abstract set/get methods to the dependent object class (EmailDO.java)for the remote interface of the EB it should refer to (Person.java). I also modified the deployment descriptor to have a CMR field in the dependent relationship section and a CMP field in the dependent section. I realize that the presence of the CMP-FIELD tag violates the spec, but Orion will not deploy dependent objects without it (it complaines that it can't instansiate an abstract class that it had generated). It all now looks like the Order-Lineitem example in the PD1 spec. After Orion deployed the app, I ran it and looked at the database. Orion had correctly created a table to hold the dependent (since its a many it needs its own table), but the field for the Person EB remote interface (which is the EB that the dependent is created by and should refer to) was named VALUEPERSON and had null as its value. This seems to indicate that Orion is not understanding that this field is supposed to be a CMR field. I reviewed the spec and there is no requirement that I manually set the Person remote interface in the dependent object, but I doubt thats the problem anyhow, since Orion named the person field "valueperson", indicating it thinks person is just another CMP field. Anyhow, I think I did everything right and I posted the code below. If someone sees something wrong or has any suggestions as to what I should try, I would appreciate you correcting me.

Thats too bad. If your in a hurry, I can understand, but for what you get, you can't go wrong in my book. It is frustrating at times, but these are the growing pains of small companies too. Good luck with WebLogic or something..it took me 3 weeks to get an email back on one SIMPLE question, and to call them would have cost us over $100 an hour. I tried that..and wasted 2.5 hours waiting on the phone. I won't make that mistake again. To be honest, I really don't think any vendor addresses the needs of support very well. It would be grand if they had 1500 people waiting by phones who were actual developers, knew the low-level technical questions that are often the ones asked, and so on. That just isn't the case in any vendor that I have bought software from. I feel bad for you that your not getting responses, but I doubt you'll get much better support with the $15K per cpu WebLogic or any other vendor.

To make my changes, I added abstract set/get methods to the dependent object class (EmailDO.java)for the remote interface of the EB it should refer to (Person.java). I also modified the deployment descriptor to have a CMR field in the dependent relationship section and a CMP field in the dependent section. I realize that the presence of the CMP-FIELD tag violates the spec, but Orion will not deploy dependent objects without it (it complaines that it can't instansiate an abstract class that it had generated). It all now looks like the Order-Lineitem example in the PD1 spec. After Orion deployed the app, I ran it and looked at the database. Orion had correctly created a table to hold the dependent (since its a many it needs its own table), but the field for the Person EB remote interface (which is the EB that the dependent is created by and should refer to) was named VALUEPERSON and had null as its value. This seems to indicate that Orion is not understanding that this field is supposed to be a CMR field. I reviewed the spec and there is no requirement that I manually set the Person remote interface in the dependent object, but I doubt thats the problem anyhow, since Orion named the person field "valueperson", indicating it thinks person is just another CMP field. Anyhow, I think I did everything right and I posted the code below. If someone sees something wrong or has any suggestions as to what I should try, I would appreciate you correcting me.

I worked with one other J2EE vendor that also gave good support (sorry, forgot their name). Hence my expectations of decent support.

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

I'm recently taken over development of a site that's got a database of about 10,000 records, but when I perform a search on them I find my CPU useage rockets to 98% and maintains that level for approximately 30-40 seconds.

This resulted in a 303883 byte file, which was 5600 lines long. Most of this output was like the block above. To me this looks like Orion's allocating and freeing massive amounts of memory and dynamically created loads of instances of the GBP bean (GBP = Great Britain Pounds, Sterling currency). Part of the search will be converting from the records native currency to Sterling, so possibly Orion's creating a new GBP bean for each and every record returned from the database. Opinions, suggestions, hints or guesses greatly appreciated. Gareth White.

Re: Ok. I feel dumb. Data Sources and MS SQL.
Kimberly,
Take a look at the FreeTDS JDBC driver for MS SQL Server:
http://www.freetds.org/download.html
Follow the link to the ftp site. The Jan 2000 jar file appears to be the
last 'release' version but it may have some problems depending on the
features you need. We've recently used the Sept 2000 snapshot, which as I
recall has to be built. There were a few minor changes, declaring certain
classes abstract, to get it to compile in our environment. I can dig out
the details if you really need it. For the most part we are using
HypersonicSQL for prototype and Interbase for production databases.
Regards,
Earl

Re: Orion doesn't interpret Javascript correctly
Andrew,
The reason this is happening, is that when JSPs are compiled, Orion
recreates them slightly to insert code for url-rewriting for
session-tracking. Obviously it is always recreating the tag with attributes
enclosed in "".
The short term solution to your problem is to switch around your '' with
your "". e.g.
from: onmouseout='csne_button.src="/images/lv1-off_04.gif"'
to : onmouseout="csne_button.src='/images/lv1-off_04.gif'"
The long term solution is to register a bug report with Orion (they do not
have time to read all messages on this list). You can do this by using the
bug-tracking system at http://www.orionserver.com/bugzilla/, or mailing
[EMAIL PROTECTED].

All,
I have a fully functional webapp that runs perfectly under Tomcat (albeit

onmouseover and onmouseout routines of Javascript. For example, one of
the tags looks like this:

onmouseover='csne_button.src="/images/lv1-on_04.gif"'

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""

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?
