Re: Iterating over Hastable ??

[Dan Miser]

The opening tag should read like this (note the lack of the terminator):
  

It looks like this is a bug in the docs.

Also, be sure you include a reference to the logic TLD in the JSP page.

The  and  tags do this. They are documented

Re: ITERATE-TAG

[Martin Cooper]

The getSalesProductHt() method must be public for the iterate tag to be able
to access it. You have it declared as protected, which is why you are seeing
the exception.

That was fixed fairly recently. The latest nightly builds do the right thing.

RE: Pooling with Oracle database

[Abraham Kang]

Hi All,

Is there any specific reason oci8 will not work with iPlanet?

I have used the Oracle oci drivers before and all that is required is a
client install of Oracle on the box that will be accessing Oracle.  All
"OCI" means is the JDBC drivers will be using the native SQL*NET drivers
(from the Oracle client install) to access the database instead of SQL*NET
implemented in Java (thin).  In addition, you have to make sure the oci*.dll
file is on the PATH of the iPlanet box.

retaining a reference to an object using digester

[Derek Harding]

I was wondering how to retain a reference to the first object created with
the Digester.  I don't quite understand the user's guide.  It says to push
the object onto the stack before parseing.  When I do this I get an End
event threw exception java.lang.NoSuchMethodException.  Any ideas?

RE: Pooling with Oracle database

[malcolm davis]

Yes, your correct, I meant ‘oci8’.  Too many cups of Java. :)

The issue with connection pooling depends on your production
environment.  For instances, if you plan to deploy to iPlanet,
you can NOT use ‘oci8’ directly, you have to use ‘thin’, or use
iPlanet’s connection pooling.  iPlanet will not allow you to use
‘oci8’ directly.  This might be a problem with other Application
servers.

The typical use of the ‘thin’ is in a connect/disconnect type
scenario.  What could happen, (and what I have seen), is that
phantom connections on the Oracle database occurs when there is
network problem.  The phantom connections use Oracle process.
For some reason the open ‘thin’ driver can cause these phantom
connections.  (I don’t know why, our Oracle admin has developed
a process to recognized and kill these connections)

The ‘oci8’ starts an Oracle process for each JDBC connect.
‘oci8’ connects and disconnects quicker than the ‘thin’.
‘oci8’ runs around 30% faster.

Another thing to keep in mind is PreparedStatements.  Having
PreparedStatements ready to use is a wonderful way of increasing
performance.  Instead of having a connection pool, you could have a
PreparedStatement for each thing you need to query.  PreparedStatement
uses an Oracle Bind.

Connection pooling is about 3x faster than connect/disconnect.
PreparedStatement pooling is about 5x faster than Connection pooling.

We have been able to drop some of our query times from 700 ms to 40 ms
using PreparedStatement.  It all depends on your application and
environment.

AW: AW: using log4J with Struts

[Rainer Alföldi]

Hi 
Azeem,
 
I 
think I attached all needed files. I just renamed them and deleted everthing not 
needed for log4j.
 
- 
Startup-mailinglist.java:
Contains public void init(ServletConfig config) which 
is called during servlet initialisation. This method calls private void 
initLog4J( Properties initProps ).
 
- 
init-mailinglist.conf:
This is the properties file used by Startup-javaand 
contains all parameter used to init log4j. (Basically path for log4j config file 
and time intervall for the reload option of 
log4j.)
 
- 
log-config-mailinglist.xml:
this is the xml-config file for log4j. here you define 
what packages should be logging where to and at what logging level. This file is 
used in Startup.java at "DOMConfigurator.configureAndWatch( url, reloadTime );". 
Check the log4j documentation if you need more support on 
this.
 
Moving the application transparently? The appender 
files are still hardcoded. If we ever have to much time during this project, 
we´ll fix that up... ;-)). Everthing else is independent of absolute 
paths.
 
 
Greeting
 
Rainer

  You forgot to attach the routines and log4 J config file. I am new to both 
  Struts and Log4j.So what it is coming down to is you define init params in one 
  of the routines you are talking here and then reference them in web.xml, so it 
  gets registered with controller servlet. Could you send a sample of web.xml 
  with log4J categories registered in it along with some init routines.
  What would be the best way of passing config file for log4J to 
  PropertyConfigurator(config), in cases where you are developing your 
  application in one environment and then want to move your application 
  transparently to a differently env without affecting passing of config file 
  location(e.g moving from Windows to Unix) Thanks

AW: using log4J with Struts

[Rainer Alföldi]

Hi 
Jon,
 
we set 
up a startup servlet, that initializes our application. This is very simple and 
basically just calls various init routines. (No subclassing) After that the 
ActionServlet is called.
 
All 
applications use init.props to get up and running. The same with log4j. I have 
attached the routines for startup as well as the configuration for 
log4j.
 
I 
really wounldn´t start mixing the ActionServlet with anything else but 
Struts.
 
Hope 
this helps.
 
 
Greeting
 
 
Rainer

Yes, In the init() method of the controller servlet 
define all your categories and give them a priority. You may also want 
to put the categris in web.xml so you can read them in runtime and thus be 
able to change the log detail level (i.e. only ERROR log messages) when you 
are in production.

actions without using struts-config.xml?

[Derek Harding]

I am wondering if there is a way to call actions without going through the
struts-config.xml.  For example if i have just action-mappings in an xml
file similar to what is in the struts-config, and parse the xml with the
digeseter, am I able to call actions this way?  if so how.  thanks

Re: using log4J with Struts

[Jon Wilmoth]

So your suggesting subclassing the default 
controller, org.apache.struts.action.ActionServlet, to override only the init 
method?  Also, I'm not familiar enough with the web.xml format as to be 
able to configure the org.apache.log4j.PropertyConfigurator.  How would one 
do this?
 
Thanks,

RE: contribution - menuing component

[Scott Sayles]

Ted Husted has gracially put a copy of my Struts compatible menuing
component on his site at http://husted.com/about/struts.  Thanks Ted.

The basic overview:
Menus can be modeled in an XML file and displayed by JSP via tags.  The
strings used to display the menus in HTML are contained in a properties file
that can be modified (or just use your own custom one).  Customized menu
displayers can be used by implementing the MenuDisplayer interface.
This is in it's early stages and is a work in progress.  Please review the
README for more specific info.
>From my point of view, this is probably more suited for web based
applications as opposed to content driven ones.

Notes about the example:
The example has been internationalized for Russian (with english being the
default).  Just switch your browser language to Russian to see the Russian
prompts.  Unfortunately, I don't have a firm grasp on creating dynamic menus
that are mutli-browser compliant.  So, to see the dynamic menus properly
please use IE 5.0 > (sorry :( ).  I would greatly appreciate some assitence
in the area of dynamic menus.

I've tried to describe most of what's going on in the README.  However,
please feel free to e-mail me/and or the struts list about any specific
questions or comments.

Thanks

Re: Internationalized JavaScript?...Solved!!

[Dallas_Browning]

I do appreciate the suggestions presented to me.  Let me share with you how
I solved the problem.
It was actually quite simple.  I simply added the following line to my
resin.conf (I'm using resin, but the same type of solution should work for
anything) file:
  
That way I can still keep the ".js" extension, but it will be considered a
jsp file to the servlet container.  I then placed the bean:message tags
wherever I needed internationalized text (example: confirm("" )) and ... voila!  It works!  I think.  I tested it
only a couple times and only in one instance, but I think it will work for
what I need it for.

We chose to do option 1.  We found it to be the most flexible.

RE: CVS directory structure

[Assenza, Chris]

How it is deployed in production and how you develop will probably look
different.  I prefer to have a tree such as:

Project Name
- build
- dist
- doc
- src
- bin
* stuff for building app (you should use ANT IMO) or
other executable utils (like bat files)
- com
* packages,etc. incl. utils, ejb's, all that.
- docroot
* JSP's, HTML, etc.
-images
-scripts 
*for external javascripts
-styles
*for stylesheets
-WEB-INF
*web.xml, tld's, etc.
-lib
*libraries supporting web app, such
as struts.jar
- lib
* for full third-part distributions, like the whole
struts.zip, ant, jaxp, regexp. That way developers have consistent releases
available to them - no need to d/l and unzip. 
- META-INF
* deployment descriptors for EJB's (if necessary),
application.xml (if necessary).

This type of setup has worked so far for me. If done correctly using ANT, it
will build into how it should look deployment wise, once there (it will do
this under build directory) ANT jars everything up and you should be able to
drop your war or ear into some server's deploy directory and that's that! :)

What has changed in the DataSource part?

[Shamdasani Nimmi-ANS004]

Hi,

My application works great with struts  version 1 of 1/29/01 but now I want to move to 
the latest version of struts and its not working. No changes have been made to the 
application itself. I have tried even beta 1 version and other versions after that but 
no luck.

The problem seems to be the DATASOURCE. I do not get an error but it seems the 
application is not connecting to the database. Has something changed in Datasource 
definition in struts-config file.

This is what I have it defined as(and it works fine with 1/29/01 version):

  



Thanks in advance

Subject: using struts in a load-balanced environement


I am very curious about whether the struts framework could be
applied in a 'load-balanced' or 'webserver-farm' environment.  One of the
main requirements of the application I am currently working on is that it
function properly in such a distributed or load-balanced environment where
each request may or may not come from the same web server.
This obviously precludes us from using session and application
scopes in the application.  We have been using the database to maintain
state, but it seems like a very inefficient and dirty solution.
I would love to be able to use the model 2 architecture (and
specifically the struts framework), but it seems like most of the benefits
can only be had in an environment where the same web server will be used for
each request (our load-balancers support 'sticky-sessions' but these rely on
cookies and we don't want cookies to be a requirement for using the
application).
Am I missing something?  Is there a way to effectively use struts
and the session and application scope in a load-balanced environment? 
I greatly appreciate any advice that anyone has on this subject.

Check out the sample app! :) Here's the code for the logon screen that gets
the data from the ActionForm.

String username = ((LogonForm) form).getUsername();
String password = ((LogonForm) form).getPassword();

LogonForm is the name of the Form Bean and form is from the arguments you
mentioned (ActionForm form). The getXXX() methods are methods in your Form
Bean that match up to the form-fields on your JSP! :)

That's just an example, but it should be pretty easy for you to replicate
with your bean, MyBean.

The 'scope' attribute does not apply to the  element. It applies
aonly to the  element, as you use it below.

It seems odd that your form is under the Struts package, but it won't cause
any problems.

This looks OK. When doSomeAction.do is invoked, Struts will look for an
instance of your form in the session, under the attribute name "myBean". If
it does not find one, it will create a new one for you. It will then
populate the bean with the values from the request.

> So in ProcessMyBean class, i instantiated object MyBean with:
> MyBean mb = new MyBean();
> and then i called the getter to get the value which was set before:

I think this is where your problem lies. You should not be creating an
instance of your form bean. Struts will do that for you, and call the
appropriate setter methods based on the query string for the request. The
form bean will then be passed to your action's perform() method, and you can
call the getter methods as necessary.

Hope this helps.

RE: Communicating with EJB's from Action

I like this description, mainly because it sounds like what I have been
doing. Something like this might make a good section in the documentation -
Struts & EJBs. I would consider the stateless session beans part of the
model because they contain business logic. You also talk about "basic value
checking of attributes". Would you also do this same value checking in the
ActionForm validate method?

Bean that match up to the form-fields on your JSP! :)

That's just an example, but it should be pretty easy for you to replicate
with your bean, MyBean.

The 'scope' attribute does not apply to the  element. It applies
aonly to the  element, as you use it below.

It seems odd that your form is under the Struts package, but it won't cause
any problems.

This looks OK. When doSomeAction.do is invoked, Struts will look for an
instance of your form in the session, under the attribute name "myBean". If
it does not find one, it will create a new one for you. It will then
populate the bean with the values from the request.

> So in ProcessMyBean class, i instantiated object MyBean with:

> and then i called the getter to get the value which was set before:

I think this is where your problem lies. You should not be creating an
instance of your form bean. Struts will do that for you, and call the
appropriate setter methods based on the query string for the request. The
form bean will then be passed to your action's perform() method, and you can
call the getter methods as necessary.

Hope this helps.

I have begun to work on menu components for an internal library I am developing with 
the following features:
- menu support localization and can be static or dynamic (possibiliy to add / remove 
items)
- static menu are created using special tags in the jsp page.
- dynamic menu are created in the Action class, put in the session/request and 
displayed by a tag.
- submenu can be expanded / collapsed. Submenu status is stored with cookies on the 
client browser (for IE4+ NS6+)

I can post the code with some exemple next week.

Re: Pooling with Oracle database

[Robert Hentosh]

I think what was meant was oci8.  The valid values are thin, oci8 and kprb.  

The thin driver is entirely written in Java.  

The OCI is a mixture of C and Java, so that is the reason it can't be used
in applets, since the C portion is not platform independent.  

The kprb is for, as the docs say, "server side JDBC driver when running
inside [the] server".  Apparently that is useful when used with CORBA.  

If you want to use OCI then you need to make sure the oracle OCI client
library (written in C) is installed on your client. 

I am not sure what Malcolm meant about the thin not being designed for
connection pooling.  I haven't heard of any issues with connection pooling
and using the thin driver.  In fact Oracle's own documentation
(http://otn.oracle.com/tech/java/sqlj_jdbc/htdocs/jdbcwhpap.htm) mentions
using connection pooling with the thin client. Did I miss something?

If you are trying to get your connection up ... then just use the 'thin'
driver.  I am about to try the OCI driver to see if there is any performance
improvements with my application.

Could you give the error message ? What does the browser display ?

Here are some points you can check:
- do you include the tags to use the taglibs ?
- do you put your bean in application scope under the name "custom.LanguageBean" 
somewhere (for example in an Action) ?
- does this bean have a method getLangCollection() giving a collection ?

Hope this help,

Re: Can i get the exact Exception.

[Todd Hoff]

Usually the web server will have logs where you
can get more information. Apache, for example, has error
and access logs. You should look at both to help figure
out what is going on. The other way is to try and run
the code standalone, without the browser. And your
server system may have logs too.

Re: .properties file

[Ted Husted]

I believe the message resource is implemented as a hashmap. The resource
is loaded into memory for each locale (when 1 or more users need it),
and so storing a relatively big amount of text this way may be unwise. 

You want to determine the locale within your view and then display or
include the alternate text that way. I would then document the other
text files as comments in the application resource file, so that it is
still the master reference to the i18n text. You might even store the
reference to an include file in the application resource and read it
back to determine the user's locale.

Re: Validating dates

[William Jaynes]

Here are some utility methods I use for date validation and rendering to and from 
strings. Nothing
fancy.

Antwort: Re: Pooling with Oracle database

[michael . brohl]

Hi Craig,

I tried the first example (servlet.findDataSource(null);) but get the following
error when compiling
my source:

"LogonAction.java": Error #: 314 : cannot access class javax.sql.DataSource;
neither class nor source found for javax.sql.DataSource at line 75, column 13

Can you please tell me where to find the needed package?

Thank you.

Regards,

Michael Brohl

With this entry in struts-config.xml, Struts will create a single
connection pool, and will also make it available in different ways:

* If you have a reference to the controller servlet (as in an Action),
  you can call servlet.findDataSource(null);

* If you have access to the servlet context (as in a different servlet
  in the same webapp), you can call
  getServletContext().getAttribute(Action.DATA_SOURCE_KEY);

* In a custom tag implementation class, you can call
  pageContext.getAttribute(Action.DATA_SOURCE_KEY,
   PageContext.APPLICATION_SCOPE);

* In a scriptlet embedded in a JSP page, you can call
  application.getAttribute(Action.DATA_SOURCE_KEY);

In all of these cases you are referencing exactly the same connection
pool.

RE: Internationalised 'alt' text

[Howard Moore]

I see, you are using the html:image tag not the html:img tag. Looking at the
source for the latest version (the version in 1.0b1 is broken) there is a
bug that stops the altKey attribute working. 
 
I have reported it to bugzilla. See
http://nagoya.betaversion.org/bugzilla/show_bug.cgi?id=1155
  for details.

I am sorry for sending this email again. But I made a mistake to point to
"name" attribute. This attribute has to be equal to "", because I do not use
it. But no attribute "alt" was generated.

P.S. here is my statement with the tag:

As you can see name is empty.

It's possible I suppose. I've tried it with Tomcat 3.2 using pageKey rather 
than src and it works ok (using Struts 1.0b1). What happens when you try to 
use the tag, e.g. what html is produced or what exception is thrown?
