RE: Orion's JSP generated code

[Kevin Duffey]

I have 
noticed the same thing. There seems to be no way to avoid this. I have no idea 
why they do it too..it does add tons of empty lines throughout the 
html.

  code
  Hi forum,
   
  I have noticed that when I use scriplets or 
  tags in my JSPs , orion puts "\r\n" into the output stream code for 
  each tag. This results in many blank lines in the generated HTML code. In 
  comparison, PHP scriplets do not produce these blank lines. 
  Does anyone know how to "beautify" the generated code?
   
  Thanks in advance,
  Sergei.

RE: Disappearing env-entry-mapping from orion-ejb-jar.xml

[elephantwalker]

not just env-entry-mapping, its just about everything in the
orion-ejb-jar.xml file.

This is bug 512. I had the problem with group-role mapping. Buts its the
same thing, when server restarts or redeploys the app the orion-ejb-jar.xml
is GENERATED and not COPIED.

You will have to regress to version 1.5.1 as a workaround.

Hi,

Does anyone have any idea why we would be seeing an env-entry-mapping
disappear from orion-ejb-jar.xml upon deployment?  There is a stateless
session bean that reads a value
MSSQL
from a stateless session beans entry in orion-ejb-jar.xml.
And upon deployment the first time, it spits out the right value over and
over (we're forcing it to read the value each time another bean uses the
stateless session bean to read it).  But when we restart the server, the
bean reports the default value instead of the mapped one.  What's more, the
entry is completely gone from the orion-ejb-jar.xml file.

I can provide more information, but I thought I'd check first if this smacks
of anything obvious.

Thanks,
Rian

Re: Shutting down orion server!

[RejathM]

Hi Rajiv,
You can stop the orion server by going to the orion home directory
where admin.jar file is availalble and in command prompt you can type
java -jar admin.jar ormi://:/  

where
host = ip address or if its ur machine then localhost
port = default port of ormi is 23791 if its not changed then you can
avoid this option
  &  =  is your password and id available in
principals.xml file under the group administrators
options = -shutdown does the shutdown
 = -restart does the restart (but it is better to do shutdown and
then start)
You can make a bat file with this command and execute it.

Has anyone compared the performance of their application running using

interested in knowing if they found a significant variance in the

to improve performance?

On the line of performance, is there a reference to performance tuning

RE: Shutting down orion server!

Please take care with runnable attachtments. If its a .bat or .vbs file,
rename it .bat.txt or .vbs.txt. Likewise for .exe files. Windows isn't as
smart as other operating systems. Another bad file type in windows is .reg,
since opening that kind of file will blow away your operating system
registry.

Bill,

I do just that, i.e. open the log file for writing in the init() method of a
dumb servlet that gets preloaded at startup.  I pick up the path/filename of
the log file from a context-param which I set in web.xml (and override in
orion-web.xml if necessary).

A better way to do all this would be to use log4j, but I haven't had a
chance to look into it in any depth.

Hope this helps,

APJ13 experiences?

[Aaron Tavistock]

I'm currently using Apache as a frontend to Orion, where Apache and Orion
are on different machines and different places in the network.  Right now it
works quite well but there are some little minor annoyances (like seeing the
Proxy servers IP in Orions logs instead of the real client, et al). 

At JavaOne Karl told me that APJ13 would solve most of these problems, so
I'm trying to get mod_jk working with Apache.  While setting up mod_jk I
notice that its pretty tomcat specific, but it seems like mod_jk or jserv
are the only options.  

It would be nice to hear if there are any good or bad experiences out there
with using APJ13 on Orion.

best way to build a link to work in different deployment configurations??

[Brian Thompson]

I have an application that during development is deployed multiple times
with the following...
http://devwebsite/customerApp1
http://devwebsite/customerApp2

In production, I'd like to deploy the applications as...
http://customerApp1
http://customerApp2

In the first case file references would look like the following

while in the second case it should be


My question is what is the best way to handle file references (links,
images, etc) within the application to support both deployments. We could
use the request.getContextPath() as a prefix to all file references

but to do this across an entire application seems like extra overhead. It
seems like there should be a more elegant solution. I've scoured the orion
doc to see if there is a way to do this through configuring websites and
webapps, but with no success. Has anyone discovered a better way??

Thanks.

Re: Datasource Question - is there a way to setup a JDBC log file?

[Bill Clinton]

Attila,
 Thanks alot.  I believe this is what I need, but I am going to 
trouble you with one more question:  Where would you recommend doing 
this in a web application?  I was hoping that there would be somewhere 
to set a log file in the definition of the datasource.  I assume I only 
need to set the logWriter once, so could I do it in the init method of a 
dumb servlet that gets preloaded? Or is there a better time and place to 
set the logWriter?

Thanks again for your response
Bill

Storing application scoped data in EJB

[Mikael Ståldal]

How do I store application scoped data in the EJB tier? Like using
setAttribute()/getAttribute() in ServletContext ("application" in JSP) in
the web tier.

Using instance attributes in Stateless Session Beans doesn't work, since
there can be several instances, and you never know which one is used. Using
static attributes in an EJB class doesn't work well either, since they may
be shared among several applications running in the same server.

Is it possible to use JNDI for this? Can I just use rebind() and lookup()
with arbitrary objects on the EJB JNDI InitialContext, just like I use
ServletContext?

To many open files ???

[Eddie]

I just noticed that the site www.orionserver.com was unreachable and it 
give the error "To many open files"
I have the same problem sometimes. How do you solve 
that or how do you monitor which causes this (without buying tons of memory) 
?  I am running Linux BTW.

Bean managed persistance - connection management.

[Manuel De Jesus]

I'm pretty new to EJBs and was wondering about connection pooling mechanism
used. In the J2EE reference implementation the examples of Bean managed
persistance (see below) obtains a reference to a datasource and then it
obtains a connection from the datasource when it is instantiated. The bean
then uses the connection for all database interactions, only calling the
close method when the bean is removed from the container. Does this mean
that for the duration of the existance of the Bean it maintains an open
connection to database ? If this is the case then that would mean if I had
1 beans I would have 1 open DB connections ... ?

Is there a reason why they do not cache the Datasource reference from the
lookup and do a ds.getConnection() in the store and load methods and then
call the con.close() after each is complete ? Does orion/app servers in
general use some kind of wrapper on the Connection object to perform the
pooling at a lower level through the Connection object ? Is there a better
way to handle the connections ... ?

Manuel

serialization of session data

[John Richardson]

Is there any way to get orion to serialize session data
quickly?  I'm looking for a setting to cause the http
session to be passified quickly so I can test 
the serialization of my servlet's http session attributes.

Does orion passivate http sessions at all?

John

Location Of META-INF folder(s)

[albert]

Hi everyone, 
I just have a short query,
I seem to have configured orion to need two META-INF folders,
one at where I have said the path is at in server.xml.
It contains my application.xml file.
the other is with my classes it contains my application-client.xml and my ejb-jar.xml 
files,
What have I done wrong?
Please note that ejbs deployed still work, I just think this loooks incorrect!
Where is my configuration problem?
Thanks,
Albert

Orion's JSP generated code

[Sergei Batiuk]

Hi forum,
 
I have noticed that when I use scriplets or 
tags in my JSPs , orion puts "\r\n" into the output stream code for 
each tag. This results in many blank lines in the generated HTML code. In 
comparison, PHP scriplets do not produce these blank lines. Does 
anyone know how to "beautify" the generated code?
 
Thanks in advance,
Sergei.

AW: EJB, JDBC and transactions

[Jens Stutte]

It's not only OK - you must do it (the connection returned is a wrapper for
a pooled connection and returns it to the pool after the transaction has
finished).
Furthermore you should check very carefull to close explicitely all created
statements, too - some databases will make trouble, otherwise.

Regards

Jens Stutte

SV: EJB, JDBC and transactions

[Mikael Ståldal]

> U should manage the JDBC connections as u would do normally.

And that is?

Should I do like this in every method?

{
Connection conn = dataSource.getConnection();

// use the connection

conn.close();
}

Is it OK to close() a connection even if the transaction isn't finished?

connectionpooling

[Morten Wilken]

i was wondering what the most commen strategy is 
concerning using the connection pool. 
Do you lookup a new Datasource for each call to the 
database (thus keeping connections the shortest time) or do you look up per 
request (thus minimizin lookup overhead)?
what is the best strategy, how do you guys do 
it?
 
sincerely

Re: clustering problem

[Morten Wilken]

i got it to work quite by chance (it figures, 1 week of failure, and 5 mins
after i posted i figured it out)

and i can offer this piece of advice.. as i stated i followed the howto on
orionserver.com, and the only thing i added was the load-on-startup=true
attribute in the default-web-site.xml, so i guess this is vital

cheers
