Re: How do you tell orion not to autocommit?

2002-05-25 Thread prasanth sb 

Hi Keith,
 If you are using Bean managed persistence, then get the connection 
object using jndi lookup, then use connection.setAutocommit(false). I am not 
aware how to do this in container managed persistence.Can some great guys 
explain this?Wish you a good day.
thanks,
Prasanth
God gives you more than you expect

Hello,

I am running orion with a datasource and  some jsp's with some jdbc beans.
When I insert/update/delete it seems to be set to autocommit. How do I tell
orion not to autocommit?

Thanks,

RE: XSL and Sitemesh on Orion

2002-04-29 Thread prasanth sb 

Dearest elephantwalker and other dearest friends,
   I have a doubt in this xsl rendering.
I used xalan and xerces parser which orion uses for xml to html rendering. I 
used my own xsl servlet to port my code to any application server which is 
not having an xsl servlet. But I am ending up in one trouble. Transformation 
is working fine. But if I need to output as xml,
I will use response.setContentType(text/xml); this works fine in servlets. 
But when I use the same in jsps in an ear file, this donot happen. Can we 
change the content type of jsp's?

thanks,
Prasanth.

Dear Peter,

Theres a bug in sitemesh so that only jsp files work. I believe that xsl
would have the same limitation. I reported this on sourceforge. There's an
easy fix to this:

http://sourceforge.net/tracker/index.php?func=detailaid=534456group_id=989
0atid=109890

and

http://sourceforge.net/tracker/index.php?func=detailaid=534772group_id=989
0atid=109890

Of course you will need to make the changes in the sitemesh code, and
re-build it, but that's a snap. I would attach the fix on elephantwalker,
but I am unclear about the Opensymphony license...any way the links above
give the exact changes necessary to make this work.

Subject: XSL and Sitemesh on Orion


I am using OpenSymphony Sitemesh on Orion Application Server 1.5.4.

The Orion XSL servlet (default config in global-web-application.xml)
is used to transform XML files to HTML.
The transformation works fine, but the transformed HTML is no longer
passed to the sitemesh filter and is displayed without layout.

What can I do to make this work?
Does anybody have a hint, please?

If I instead of the jsp:include tag, inserts the textfile in the
jsp-page, it works. I've tried other taglibs and used a jsp:include
for the body, for both Orion 1.5.2 and 1.5.3 and I get the same error.

Am I doing something wrong? Is it Orion? Or is this not a valid thing to
do?

RE: CMP 2.0 vs BMP - Which performes better?

Hi Jeff and other dear friends,
 I had this doubt in my mind very earlier.
When we load very large amount of data from the database, how it can be

in the memory at a time?

   There are several constraints to BMP beans which make them almost
always
   perform slower than CMP beans.  In particular, the inability to bulk
   load beans from finder methods is a nearly fatal defect.
 
  I'd like to know more of the details?
 
  How does the container deal with the following finder in CMP
  differently than BMP?
 
  Collection remoteRefs = home.findSalaryGreaterThan ( 50,000);

Lets assume this produces 1000 results which you then iterate through.

With BMP beans, this will require 1001 database queries.  First the
finder, then 1000 selects to load each bean.

With CMP, it's actually rather ambiguous what will happen.  Last time I
checked, Orion will load all the beans into an ArrayList.  Yes, lots of
memory consumed, but a *lot* better than 1001 database hits.  Admittedly
a bigger problem with orders of magnitude more objects, but even with
BMP you're going to choke if the finder query returns a billion rows of
primary key data.

Some containers (not Orion, I don't think) allow you to specify that
finders should lazy-load beans.  But this brings you back to BMP
performance.  Some containers allow you to define field groups to
minimize the amount of data brought back (especially useful if you store
blobs), but not Orion.

Personally, I don't understand why containers don't implement
Collections backed by the ResultSet directly.  98% of the time, the
client just creates an iterator and walks the results.  If the client
does something that the ResultSet can't support, build the full
Collection.

See my earlier post on this thread. You can use custom finders with
_extreme_ ease in Orion. I gave an example for Oracle (since Oracle does 
not
_have_ the sql LIMIT statement). For other databases, you could use a LIMIT
statement in your custom finder.

Problem:

myFoo.setY is called but myFoo.setX is not called. Suppose I want to change
