All that will do is get you the names of the attributes bound to a
*single*
session. A common approach to session counting in a Servlet 2.3
container is to
use javax.servlet.http.HttpSessionListener. For either Servlet 2.2 or
2.3, you
can make use of javax.servlet.http.HttpSessionBindingListener, but it's
more of
a manual process.

Alternatively, JBoss might provide some sort of admin console or JMX
access to
the current sessions.

Hey Mike,

Tomcat is the standard servlet runner that now comes bundled with Jboss.

Are you using Tomcat as the servlet runner (I don't know a lot about
Jboss)
or is there a built-in one in Jboss?

Subject: RE: Actions which create sessions seem to hang

I've had my Struts application running on JBOSS 3.2.2/Tomcat for a
couple of
weeks with hundreds of simulated users at a time, so I don't think there
is
any inherent issue with the architecture.

Tools I've found useful in tracking issues like this in past are:
Running JBOSS with the JVM set to allow remote debugging so I can see
what's
going on.
Borland OptimiseIt, so that I can look for resource leaks.

Other things to look at may be the number of request processors and the
accept count of the Tomcat connector.

If all else fails I'd try and re-create the problem with a simple,
single
servlet system. This will remove any Struts, JSP etc. concerns.

Another idea would be to see if the same issue occurs in Tomcat
standalone,
or is related to Tomcat under JBOSS. This will allow you to direct your
questions to the most specific user community.

HTH,

Paul

RE: Help setting up sslext

[Brian McSweeney]

Thanks for the reply Adam.
I'll address your tips one by one.

>> I don't use the sslext form tags. I don't mention sslext anywhere in
my 
>> code or my JSP. It's purely a configuration thing.

Ok, this I did differently. I followed the examples downloaded with
sslext 
And used



Now the weird thing is - I changed this back to  to try to do

what you do, but now it doesn't even use ssl at all! 

If I change back to sslext, it uses ssl but never switches back to plain
http.

>> Are you setting up the SecurePlugin in struts-config?

Yes.

>> Also are sure that you are not specifying in the web.xml that the
page 
>> should be protected by SSL?

Yes.


>> Do you have the latest version of sslext? They brought out 1.10-3
recently.

Yes, that's the version I have.

>> Are you sure there are no exceptions buried in your logs anywhere?

Checked that, everything looks ok

>> I don't follow your hotmail example either. Are you talking about 
container-managed logins or roll-your-own?

Login or some other action, it doesn't matter. I used the hotmail
example 
because it allows you to call an action  over https, but the resulting
html page gets displayed over http. This is because the flow of hotmail
is 

login page (over http) --> run login action (over https) --> display my
account.html page (over http again). So it switches back out of ssl for
the result of the action.

Now if I've understood what you have said to me correctly, this couldn't
happen with sslext. Because we would have to invoke a second action
which had the parameter



in order to get out of ssl after invoking any secure action.

Hope you understood this, 
And thanks very much for all your help,
Brian

RE: Help setting up sslext

[Brian McSweeney]

Thanks Adam,

However, unfortunately no joy :-(

It still isn't switching back to http for other actions when 
I specify 

  

Perhaps I have to replace all 

At any rate, it doesn't seem to work the way I thought it would.
For example, if you log into hotmail, it sends the username and 
password over ssl, and then switches back to http for the resulting 
pages. This it would seem is impossible to do with sslext because 
in order to switch back to http, you must call another action which 
has:

  

Correct me if I'm wrong with any of this.

The only time the protocol switches automatically (read: tomcat switches

it automatically) is when you specify SSL in the web.xml for a URL.

To get it to switch back from SSL into unencrypted, putting



in the action mapping is necessary.

Hi Adam, 
thanks for the help.
I've put in the change in the action-mappings in the struts-config.xml
file



but the problem is, ssl doesn't seem to be switching at all. The action 
runs in https when I say it should, but all other actions then continue
to 
run in https. I was under the impression that they'd switch back to
normal 
http. Is this not correct?

Hi Brian,
your (a) is definitely necessary to enable this:

 
   
 

I have not used, or heard of before, your (b). Perhaps it has the same 
effect as (a).

So what's not working?

Help setting up sslext

[Brian McSweeney]

Hi all,

Searched the archives, but couldn't quite get a good simple explanation
of how to set up sslext.

Here's my progress so far:

1) Hook up ssl with your keystore etc on your container

2) Download sslext from sourceforge.

3) Install the sslext.jar in my WEB-INF/lib folder

4) Install the taglibrary in WEB-INF/

5) Tell the web.xml file about the tld, ie 


/WEB-INF/sslext.tld
/WEB-INF/sslext.tld


6) In my jsps import the taglibrary, eg:

<%@ taglib uri="/WEB-INF/sslext.tld" prefix="sslext" %>

7) Use the taglibrary tags when posting - eg:



9) Add sslext as a plugin to the struts-config.xml file
  

   
  
  

9) In the struts-config.xml file, for the "whatever" action add the
property "secure", eg:


  
  


Now, I've done all these, but I know there's something missing because
it's not quite working.
I've read a few posts and see these possible things I might have to do
aswell:

a) Change the action-mappings in the struts-config.xml file


b) Change the web.xml file as follows:

action
 
org.apache.struts.action.ActionServlet


  config
  /WEB-INF/struts-config.xml


  mapping
 
org.apache.struts.action.SecureActionMapping


could someone tell me if either of these steps are necessary, or what
else is necessary?

Thanks very much,
Brian

RE: [OT]formatting line breaks and tabs in emails?

[Brian McSweeney]

Hmm, very strange. I had the exact same error as Mick yesterday. 
I'm also using \n and I was pulling it in from resource bundles but 
the breaks were being ignored.

Perhaps it has to do with the mailer. My mailer is setting the type of 
message to "text/html" as you can see by my send method below.


public static void send( String replyTo, String to, String subject,
String body )
throws NamingException, AddressException, MessagingException {

InitialContext ic = new InitialContext(  );
Session session = ( Session ) ic.lookup( JNDINames.MAIL_SESSION
);
javax.mail.Message msg = new MimeMessage( session );

msg.setReplyTo( InternetAddress.parse(replyTo,false) );
msg.setRecipients( javax.mail.Message.RecipientType.TO,
InternetAddress.parse( to, false ) );
msg.setSubject( subject );

msg.setDataHandler( new DataHandler( body, "text/html" ) );
msg.setHeader( "X-Mailer", "JavaMailer" );
msg.setSentDate( new Date(  ) );

Transport.send( msg );
}


The way I fixed this Mick was by using  tags instead of /n, so 
this perhaps indicates that it's because our mails are set to type html.

However it would be nice to find out if this is the reason!
Hth,
Brian

I am trying to format email messages that need to contain line breaks,
and tabs. But when I add \n\r or \t, they just seems to be ignored.
Is there a way to do this?

[Brian McSweeney]

Easier still, you don't have to write a servlet, just a class that 
implements ServletContextListener, eg something like:

public class StartupListener implements ServletContextListener {
private Log log = LogFactory.getLog(StartupListener.class);
ServletContext servletContext;

public void contextInitialized(ServletContextEvent sce) {
servletContext = sce.getServletContext();

// run your startup code in here!
}

// implement other methods here

}

How simple is that!

You dont need to subclass the action servlet just for the init code...

Write u r own servlet(InitializationServlet)and put it in the init
method of this servlet.

When configuring the servlets in web.xml have somethign like this.


InitializationServlet
InitializationServlet
com.urapp.InitializationServlet
1


And for all other servlets , the load-on-startupvalue should be
greater than 1.This ensures that when the servlets are
initialized(Loaded), the initialization servlet is loaded first which
means also the init method will be called before any requests are
received.


Additionally u can have any startup code called from the init method of
this servlet.

Hope this helps.

Shirish

I'm converting an existing webapp to Struts.  I have some code in a
Servlet init() method, and I don't immediately see where I should put
it.  This is an authentication/authorization webapp, and the code in
question sets up an authentication handler object to be used by every
subsequent request.

What's guaranteed to get executed before the Action code?  (I'm almost
thinking Filter, and to put the object in Application scope, but I'm not
sure yet.)

Any advice?

RE: [Slightly OT] Where/how to start?

[Brian McSweeney]

I reckon you should try to read the source code of a good open source
j2ee app. Furthermore, J2EE is big - there's a lot of stuff you could
use. 
I would recommend sticking to standards. Struts is good for this, so why

not look at the struts examples that come with the struts download.
Another large part of J2EE is ejb etc. There is quite a lot to learn
there, so a good example of a project that puts it all together is 

http://sourceforge.net/projects/xpetstore

This uses more standards that you'll probably have to learn,

For example

Ant - your project build system
Junit - for testing
Xdoclet - for code generation
Struts - for your web mvc part

Learning all these by reading how someone else did it is far, far easier
than trying yourself from scratch.

Hth,
Brian

Here's what I did at my last job: I was mostly a C, JAM, Oracle
developer
but wanted to learn Java and J2EE. Try to find an approach that will let
you
learn J2EE while benefiting the company in some way.

Let your managers know that you want to learn the technology. They'll
know
that you aren't content just doing the same old thing every day, and
they
might start to look for training opportunities, whether it is sending
you to
class or putting you on newer J2EE projects.

Another way is to take a few hours each week learning a new technology
and
incorporating that into some sort of prototype that your company might
be
interested in. Take an existing application and prototype a Java/J2EE
version of it. Show it off to your managers, then move on and do some
more
prototypes. Even if it doesn't go into production, you have built real
applications in a real work environment.

Hi all,

I have a strong Perl/CGI background, but my JSP/Servlet/J2EE experience
is related only to what I did in college. My job entails C development,
but I really want to get more into this J2EE stuff.  It's so much more
enjoyable than this C work I am doing, but I can't seem to get my foot
in the door.  In looking for a J2EE development job, I keep hearing
that I need more experience, which is perfectly understandable.   But,
I can't get experience without getting a job doing it first.  My
question is, how do I get my foot in the door so I can split my boring
job and do what I really want to do?  Do I need to go full tilt and get
a certification or something like that?  Any ideas would be most
helpful.  Even more helpful would be a J2EE job in the Chicago area
where I could develop my professional career in this area.

Thanks very much!


Best Regards,
Andy

"the only reason I posted that msg was for baiting purposes"

Look, I just don't think that is helpful to anyone. If you are
deliberately saying stuff in order to bait people into a reaction then
IMHO this is the wrong place to do it. I also think that stating this on
the list is a valid enough place to state this. People responded to your
comment in order to advise others that they thought your assessment of
JBoss was incorrect. If it is your true assessment, fair enough, but you
refused to back it up when asked to, and replied that your comment was
just to bait people.

I'm not going to labor the point anymore. No offence meant at all, and
sorry if any was caused. I find this list exceptionally helpful and
pleasant.

Nonsense!
In the same way acronyms look great on resumes, they also look just
super on
product brochures.
If you use EJBs you can proudly proclaim that your application is "based
on
J2EE EJB technology"!
This is useful for impressing clueless manager types even if EJBs confer
no
actual technical advantage (and often many disadvantages) to what your
trying to do.

btw: afaik its not just distributed stuff but also transaction type

its good for (but lets face it - most dbs do enough in that regards for

If you are asking these questions, you probably should not be using EJB.
The ONLY reason to use EJB is if you are developing a distributed
application; anything else is overkill.  If you simply need data
persistence, use JDBC and use DAO, or one of the persistence frameworks:
Ibatus, Hibernate, or Kodo-JDO.

Subject: RE: ejb's and tomcat

hi!
its actually for my software project at university. i am in uni. and the
aim 
of the project is to use ejb with struts.
we are developing a transaction/payment gateway.
the ejb's will be implementing the model, ie, the actual transaction and

also merchant support functions.
since me and my group are still in uni(and learning among other things 
groupwork), we divided the tasks. so while i developed the web tier
using 
struts someone else developed the ejb's
and ofcourse now we have to integrate the two sides and hence my
question. 
we are currently experimenting with openEJB; any alternative
recommendations 
will be most welcome.

thanks
cheers
ajay

Havn't tried that though, but if you put the following in your jsp:


  

  




The staticJavascript.jsp file is the same as in my previous post
regarding validation.

I think it may work, assuming you've defined the rest properly in your
validation.xml file.

RE: newbie: Best Practice Struts/Value-Objects?

[Brian McSweeney]

Hi Darren,
I was under the impression that it works exactly the way you hope it
does.
Actually I'm pretty sure it does.
Also what might be worth looking at ( I have to look at it myself ), is 
Light-value-objects where you only populate the initial value object
with the 5 fields rather than the whole 20. This is obviously more
optimal in 
terms of db queries.

This is all pre-supposing you are using xdoclet and EJBs and xdoclet,
which
perhaps you are not.

HTH,
Brian

Subject: newbie: Best Practice Struts/Value-Objects?

Hi all!
Been working with struts and value-objects, and I am beginning to
understand the power of these two in combination. I did however run into
a snag that may be either on purpose or just ignorance on my part.

If I pass a 20-field value-object to an ActionForm (let's say an
EmployeeVO), and I only show the employee's name and address for editing
(only 5 or so fields).  They make the necessary changes and submit the
form.  What I understand is the form will populate a NEW EmployeeVO and
not make the changes to the original EmployeeVO, thereby creating an
EmployeeVO populated only from the 5 fields on the form and nulling the
other 15 fields.

I was hoping to take an existing Value-Object, only make necessary
changes from the submitted form (i.e. 0-5 changed fields and the other
15 stay the way they are), and then re-submit the Value-Object for
updating the DB, but that does not seem possible.  Am I doing something
wrong and/or mis-understanding the best utilization of Value-Objects
with Struts?  Again, I'm a newbie so any pointers, help, or examples
would be great!

thanky in advance!
-D

RE: Question about minimizing javascript loaded into web page

[Brian McSweeney]

Helps very much Saul. Cheers.

Final dumb question: 

So is the result of this that only the javascript methods pertaining to 
each jsp gets loaded into the page?

If so, do you know why this isn't the default behaviour?

Thanks,
Brian

yes

Pulled from the struts example application, basically it's setting 
dynamicJavascript="false" staticJavascript="true"

staticJavascript.jsp:
-

<%@ page language="java" %>
<%-- set document type to Javascript (addresses a bug in Netscape
according to a web resource --%>
<%@ page contentType="application/x-javascript" %>

<%@ taglib uri="/WEB-INF/lib/struts-html.tld" prefix="html" %>



-

dynamic javascripts are generated based on the particular fields of your
jsp page, say, the validation error messages etc. The static javascripts
are those validation javascript functions as defined in the
validator-roles.xml file.


Hope this helps.

Saul
