Is it legal for session bean A to create session bean B, and pass it to session bean C so that C can call on B? For example, if A is acting as a controller, B is acting as a factory, and C is acting as an algorithm. So a controller needs to execute an algorithm which requires a factory as one of it's parameters. As the algorithm runs, it calls on the factory to create the resources it needs.

Re: During development, how to allow only a couple of ips,includingmylocal system, to view the site?
Hey Kev, It seems that after that long discussion on the JSP list, each one ended up building his own MVC framework, remember that? ;) At the beginning, I also integrated this feature inside my framework but then I realised that this way I wouldn't be able to re-use it for other applications, or even for static content. That's the reason why I ended up creating a filter. But there are some things I don't like about filters: They have to be configured in the web.xml and they are not easily integrated with other parts of the framework, unless you share objetcs through the context or something simliar. What I would love to have is a "feedback" mechanism to provide the containers with some extra information/configuration that is not included in the web.xml. This way I could just configure everything in my own framework configuration file and then I would give the feedback to the container. Otherwise, if you use filters for logging, authentication, IP filtering... your web.xml ends up being extra-large and having the application configured in two places is error-prone. But well, such a feedback API is not in place so... ;) Talking about the IP filter, if you are interested, I can show you my DTD and even some code as it is nothing extra-complex. Regards, Dan Kevin Duffey wrote: Hey Daniel, That is a great idea..DUH! ;) I am using my own simple MVC framework, and I should just put in a feature in the web.xml that gets read in as an init parameter that designates ips that are allowed/now allowed to access the application.

Hi Kev, I had a similar problem but for my production applications. I wanted my solution to be flexible and server independent so what I did was create a servlet filter, as someone else has already suggested. I've had it for production for almost a month and so far so good. I have to admit that I went a little further down the road and I allowed to specify the IP/hostnames to be allowed denied through an xml file that can be read from a file, a URL or a database. That way I got maximum flexibility.

But there are so many app servers available and there isn't the time to evaluate them all so I wanted to make sure that I had not missed any gems. Q.

RE: Building an application
Logging is something that has been rather overlooked in java. The proposed
Java 1.4 contains a logging api, but in the meantime, the log4j project at
jakarta.apache.org/log4j is an excellent framework suitable for most
architectures. We use it all the time in servlets, EJBs, taglibs, etc and
it works very well.
The OpenSymphony open source project (www.opensymphony.com) contains a
class called com.opensymphony.util.Logger in oscore.jar (you can obtain and
build this through anonymous cvs) which conveniently hides all the things
you don't need to know about log4j. You use it like this:
import com.opensymphony.util.Logger;
public class MyClass {
private static final Logger logger = new Logger( MyClass.class );
...
public void myMethod() {
logger.debug( "This is a debug message" );
logger.info( "This is info" );
logger.warn( "Guess what this is?" );
logger.error( "Bad news" );
logger.fatal( "REALLY bad news" );
...
It reads in a properties file which is described in the log4j docs, and is
accessed by
the logger.config system property, eg:
java -Dlogger.config=/path/to/my/logger.properties MyClass
which allows you to switch logging on and off, and record only certain
priorities of logging, send debug to the console and error to syslog or the
Event Logger in NT, etc.
Very clean, simple and nice to use.
Hope that helps,
Dan/tastapod
ps. I have no commercial affiliation in opensymphony, but Logger is
possibly the class I use the most anywhere in java, after java.lang.String :o)

RE: Alternative Deployment
Well, then don't use J2EE. BEA support is supposed to be the best, and sure, it's pretty nice in that if you've spent lots of money, your issue can be escalated quickly, but if it is a real bug, it'll eventually come down to 'yes, it's a bug, it'll be fixed in the next service pack', which is often not due for another few weeks (by the way, this is exactly the situation I was in). I think you'll find that there are plenty of users on this list who have deployed Orion on a high-availability site that have been running smoothly for months now, it's just that when it works, there's very little reason to be loud and vocal about it.

RE: Alternative Deployment
Maybe going off on a tangent here, but why are you using apache as a web server? Orion works perfectly well as a web server as well as an app server (and much faster and more robust). Also, you can plug in support for things like php if you need them - see www.orionsupport.com for details. You could feasibly use jBoss or TomCat as an alternative app server, or WebLogic if you've got tons of cash, but I would be surprised if the first two are as stable and reliable as orion (your mileage may of course vary), never mind scalable. I haven't used apache for about 6 months now, and I have to say I don't really miss it :o) Cheers, Dan/tastapod ps. As for official support, I believe this is something the dev team are looking into, but I haven't heard any formal announcements yet. I find that asking around the usual channels - mailing list and irc to name a couple - often resolves my problems and even more often gives me new ideas.

Problem ( solution) with ejbStore() and Oracle CLOBs
Hi, I have a BMP entity bean that maps to an Oracle table with a CLOB field. I can read the CLOB in OK but when trying to write to it I get an 'ORA-01002: fetch out of sequence' error. This error can be caused by a commit being called between retrieving the CLOB locator with a SELECT... FOR UPDATE and trying to write to the CLOB's output stream. I solved this for ejbCreate() by setting the create() method's transaction attribute to 'Required'. However, I can't give the ejbStore() method a transaction attribute as it can only be called by the container. I have got around this like so: By default, ejbStore() is called by the container after every call to any method in the bean instance, whether or not the bean's state is changed. Implementing the public boolean isModified() method stops ejbStore() being called every time as the container first checks that true is returned by this method. Setting a 'Required', 'Requires New' or 'Mandatory' transaction attribute for all methods that set the 'modified' boolean to true seems to ensure that ejbStore() is now only called inside a transaction. This seems to solve the problem but I'd like to be sure that my assumptions are correct and that this WILL prevent ejbStore() from ever being called outside a transaction. Also, is it possible to set a transaction attribute for ejbStore()?

Subject: RE: Building an application
Logging is something that has been rather overlooked in java. The proposed
Java 1.4 contains a logging api, but in the meantime, the log4j project at
jakarta.apache.org/log4j is an excellent framework suitable for most
architectures. We use it all the time in servlets, EJBs, taglibs, etc and
it works very well.
The OpenSymphony open source project (www.opensymphony.com) contains a
class called com.opensymphony.util.Logger in oscore.jar (you can obtain and
build this through anonymous cvs) which conveniently hides all the things
you don't need to know about log4j. You use it like this:
import com.opensymphony.util.Logger;
public class MyClass {
private static final Logger logger = new Logger( MyClass.class );
...
public void myMethod() {
logger.debug( "This is a debug message" );
logger.info( "This is info" );
logger.warn( "Guess what this is?" );
logger.error( "Bad news" );
logger.fatal( "REALLY bad news" );
...
It reads in a properties file which is described in the log4j docs, and is
accessed by
the logger.config system property, eg:
java -Dlogger.config=/path/to/my/logger.properties MyClass
which allows you to switch logging on and off, and record only certain
priorities of logging, send debug to the console and error to syslog or the
Event Logger in NT, etc.
Very clean, simple and nice to use.
Hope that helps,
Dan/tastapod
ps. I have no commercial affiliation in opensymphony, but Logger is
possibly the class I use the most anywhere in java, after java.lang.String

Re: Including jar files in my web app ?
Title: SV: Including jar files in my web app ?
Hi Magnus and others ofcourse,
It has been a while since this issue passed by, but
that is because we have been struggling with it since.
I am still not able to include jar files that I put
in my WEB-INF/lib dir, particular: velocity.jar.
Also someone else in this newsgroup has been busy
with it, on orion 1.4.7, on the same application on a different machine and has
the same problem.
BTW: I am able to use the jar when i put it in
orion/config/application.xml with library path... it works but it
contains a static class and I need one for every application.
Everytime I
get the error that it can't find the class (ClassDefNotFound).
What I tried:
- Just putting them in the WEB-INF/lib dir, but it
can't find it.
- putting the velocity.jar in other places, like in
the root of the application.
-jar file in the WEB-INF/lib and putting the
following tag in the orion-web.xml:
classpath path="./WEB-INF/lib/" /
- and also tried
classpath path="./WEB-INF/lib/velocity.jar" /
- unpacking the jar and putting it in the WEB-INF/classes dir where the
servlets are located in packages that I call through servlet ref's
- When I put the WEB-INF/lib/velocity.jar in the CLASSPATH, yes it does
find it, but then all applications find the same velocity.jar and that doesn't
work.!!!
- Tried to include the jar int the META-INF/application.xml:
moduleejb/opt/Orion/lib/counter.jar/ejb/modulebut
is than complains:
---
Error auto-deploying application-client at velocity.jar: Unable to
find/read assembly info for /home/development/sgs/velocity.jar
(META-INF/application-client.xml)
The file exists and has the necessary tags, only it is empty as I don't
know what to put in it.
- I find in the newsgroup archive, that solved the problem by starting
orion with:
com.evermind.server.ApplicationServer insted through orion.jar
- I think I tried some more things but reallu nothing worked.
PLEASSE tell me how I can see where Orion looks for the jar file, as this
problem is really driving my comletely nuts...!!
I found a lot of little things about this subject. I tried about everyting,
but nothing helped. I lost the logic here, so hope that someone can help me out,
here, otherwise I .

RE: Application mapping - how do I know it from within the app?
I believe that the original servlet spec allowed direct access to root of the web site, but these methods were deprecated for security reasons. I have been having this problem myself, what a wonderful solution!

With a little help. I hope this function will appear in servlet 2.3 version ( and why isn't orion running 2.3?? ) anyways, if anyone else runs into this copy paste this line : String servletPath = request.getRequestURI().substring(0, request.getRequestURI().indexOf(request.getServletPath())); Which will return the mapping to the root of your application. Johan - Original Message - From: Johan Fredriksson To: Orion-Interest Sent: Wednesday, April 11, 2001 4:59 PM Subject: Application mapping - how do I know it from within the app? I'm using virtual hosts in my development to make sure that all links are correctly set, that is I can access the same app in two ways, either via appname.localhost or localhost/appname . The problem is that I'm not sure how to figure out on a jsp page which entry point was used, and this causes problem when I'm trying to map my servlet, since relative paths to servlets does not seem to work... String parsing of request.getRequestURI() seems like a way to start, but I'm not sure what how to write it, since in the future the app might be moved again to appname.serviceprovider.localhost vs localhost/serviceprovider/appname . Is there a way to get pageContext return application context? Johan

Logging
Hi,
(That mail could be for Dan who seems to work with log4j.)
I am trying to use log4j to debug my application.
(I could not download opensymphony...the download link is disabled)
This is how I set it up:
static Category LOG4J = Category.getRoot();
BasicConfigurator.configure();
Layout layout = new PatternLayout("%d{HH:mm:ss} %-5p %c %x - %m%n");
//not sure about the output. I have tried Syste.out as well
LOG4J.addAppender(new FileAppender(layout, System.err));
//no debugging if not set
if((debugPriority = System.getProperty("debugLevel")) == null)
LOG4J.setPriority(Priority.toPriority("FATAL"));
if(LOG4J.isInfoEnabled()) LOG4J.info("Application started...");
I have 2 problems:
1) The statements are printed twice, but in different format:
The first one is the default one, the second one is the one I specify
0 [ApplicationServerThread] INFO root - Application started...
20:12:37 INFO root - Application started...
2)As is it the log are printed on the console. Is is possible to redired
them to the application.log ???
Thanks,
Olivier
Kawa 5.0 Ent and Orion 1.4.7
Hi all, has anyone succesfully been able to configure Kawa 5.0 Enterprise with Orion 1.4.7 ? What I'm looking for is all the parameters needed for the EJB serve dialog box like EJB Server parameters, Packager, Deployer, Unddeployer and so forth. I've tried Allaire but no answer so far besides read on the FAQ. But there is nothing there. Thanks, Brynolf _ Get your FREE download of MSN Explorer at http://explorer.msn.com
Re: Management Console...
In the same vein, there's a menu item to add a server. Does this imply adding another application server? Another Orion server? Yes, e.g, I have the console running on an NT workstation, but I can connect to an Orion server on another Linux box. Derek
RE: request.getParameter() not working under solaris?
I had the same problem when loading data from the database ( swedish language ). They got messed up on the way. So the resolution in my case was to make sure that the shell running orion supported swedish chars. Got it working. The solution was to specify environment variable LANG: export LANG=en_US.UTF-8 And it seems that specifying content type and charset with a meta tag is not enough. It has to be set using a %@ page % directive as well. Now I have to find out how to define et_EE.UTF-8 for my system. thanks, Taavi :-) Hope this helps. Johan it sure did

SaxParseException-Help out
Hi all, Can anyone help me out.I have a jsp that sends Userid and password to another jsp that checks the values with an XML file.If xml parsing is sucessful, the values should be put into a JavaBean that has a session scope.So the ensuing jsp pages can make use of it.But while parsing I get the following message on the Orion console.I don't even have any tag called meta in the XML to be parsed.It is rather bewildering. Thanks. C:\orionjava -jar orion.jar Orion/1.4.7 initialized org.xml.sax.SAXParseException: Expected "/meta" to terminate element starting on line 1.
