Re: db error

[Daniel H. F. e Silva]

About that url try this:

  jdbc:oracle:thin:@oci8:1521:ora9i

considering 'oci8' is your database server name and 'ora9i' is your Oracle's instance 
(service)
name.

 Daniel Silva.

[OT] Is it possible to use commons-el in a standalone application?

[Daniel H. F. e Silva]

Hi,
 I know this is an off-topic message, but as many people here works with Jakarta 
Commons
components, i decided to start my search in this list.
 I was thinking about writing a Swing app where its config file would be a XML file. 
And i'd like
to put EL expressions in that file. So, my question is: is it possible to embed EL 
into a
standalone app? 
 I was reading commons-el API docs and they make a lot of references to JSP 
implementation classes
(PageContext, VariableResolver, etc). So, in first glance, looks it is not possible. 
Is my
conclusion right?

 Thanks in advance for any hint.

Regards,
 Daniel Silva.

RE: [Suggestion] struts-user-newbie list

[Daniel H. F. e Silva]

Hi Andrew,

  Good point.
  Freedom of choice is very appreciated and is one the axioms of open-source community 
;-)
  By the way, I'd like to invite all newbies and even Struts gurus to join us at 
#struts_users IRC
channel at irc.darkmyst.org. There you can get help and meet some of the coolest guys 
in Struts
world (myself included ;-)). You can, at least, have fun there!

Cheers,

Re: [Suggestion] struts-user-newbie list

[Daniel H. F. e Silva]

Hi,

  My point is: will Struts gurus that participate this list subscribe to one more 
list? I think
they are too busy for increasing their email load a bit more.
  Newbies could get a better help if, before posting to this list, they did homework: 
i mean, read
Struts docs, Google, etc. I'm not sure about this number, it is just a guessing, but 
based on my
experience in this list, 95% of the questions are already answered. You just have to 
find that
answer, and that is what Google is for.
  
  My two cents.

Cheers,
 Daniel Silva.

Re: Chart generation Framework

Re: Chart generation Framework

[Daniel H. F. e Silva]

Hi Vinicius,
  Cewolf is really a good option. It is a taglib that abstracts a lot of JFreeChart
complexity. I used it in some projects and it did a great job. As far as i know, it
is the best open-source option. There are other libraries, but Cewolf+JFreeChart offers
the largest amount of features.

Cheers,
 Daniel Silva.

Re: struts and ibatis

[Daniel H. F. e Silva]

Kelly,

  After looking for good options to make my applications simple, i found iBATIS.
It is a very nice piece of software and, in my opinion, based on experiences, it
is ready to go to a production environment. I used iBATS DB Layer and SQL Maps
in two projects and it did very well.
  New 2.0 version has amazing features. It is still in beta stage. But i'm sure
being in beta is not worse than Windows + SP1000. In fact, i trust more in iBATIS
beta than in any M$ 'production' software as you have access to the code and if you
find a bug you can fix it.
  If you'd like to know more experiences about iBATIS join us at #struts_users IRC 
channel
on irc.darkmyst.org.
  Other cool resource for iBATIS newbies is Rick Reumann's iBATIS lesson 
(www.reumann.net). A
simple and useful app showing how to use iBATIS.
  Hope i helped you.

Cheers,
 Daniel Silva.

Re: SV: Struts and Action errors

[Daniel H. F. e Silva]

Hi Vinicius,

  I think you are a bit lost regarding Struts. Take a look at www.reumann.net.
Very good tutorials. They will help you to understand better how to use Struts
properly.
  By the way, i'd like to invite you to a very good struts chatroom. Point your
IRC client to irc.darkmyst.org and join #struts_users channel. You'll find great
guys there (and a girl too!), that have strong Struts experience. See you there!

Regards,
 Daniel Silva

Re: mapping question

[Daniel H. F. e Silva]

Vanessa,

  As discussed a time ago on this list, it is considered a best pratice
to go through an action all the time. So you can decouple your view layer
in a way that makes your life easier. There are plenty of learning resources
around the Internet about Struts, but i'd like to recommend www.reumann.net
and www.ibatis.com. iBATIS is where you'll find a nice implementation of PetStore
sample application that could be useful as a starting point to your apps.

Cheers,
 Daniel Silva.

PS: If you need help during your day you could go to #struts_users IRC channel at 
irc.darkmyst.org
You'll meet nice people and very skilled java and struts developers there.

Re: with formatKey ???

[Daniel H. F. e Silva]

Mauricio,
 If you have access to JSTL in your server container you could try formatting taglib.
  and  are two very useful tags. I use them a lot.
 They accept formatting patterns like classes from java.text package (In fact, they 
use classes
from java.text package on their implementations). Take a look on any JSTL book or doc.
 In worst case, you have to code a method or a custom taglib to transform your number 
attribute to
a String object and then process it to get proper formatting. I'm sure that is pretty 
easy.
 Hope this posting is useful to you.

Regards,
 Daniel Silva.

PS: Nice to see other brazilians in struts-users.

Re: RES: [OT] Looking for a Taglib

[Daniel H. F. e Silva]

Hi Tiago and Linda,
  JavaScript is really the best option to this task in my opinion. I suggest taking a
look at http://javascript.internet.com in section Form. Lots of nice scripts! Including
one script that does what Linda wants.
 Hope my tip was useful.

Regards,
 Daniel Silva.

Hi Bob,
 I think you could try  or, better, JSTL tag .
I'm not a JSTL expert but i know you can determine scope to be used by .

RE: Please help with this error "???en_US.errors.required???"

[Daniel H. F. e Silva]

Hi Vivien,
 I think it depends on Struts version you are using. I use 1.1 and everything works 
fine.
Your  config tells Struts to look for your resources at package
org.apache.struts.webapp.tiles.dev1-1. So, you should have, for instance, this:

  WEB-INF
--
 |
 |--- classes
--
 |
 |--- org/apache/struts/webapp/tiles/dev1-1
  
|
| - ApplicationResources.properties

  If you are not using 1.1, please, upgrade to. If problem still happens, you know how 
to find us.
  Hope it was useful.

Regards,
 Daniel.

Hi Vivien,
  Sorry, but i did not make myself clear. Property you have to check existence in 
web.xml is
"application". It has same effect as "parameter" attribute of . So,
if you find it there (web.xml), remove it.
  Hope it helped you.

Re: Please help with this error "???en_US.errors.required???"

[Daniel H. F. e Silva]

Hi Vivien,

  Take a look at your web.xml. Maybe you copied it from Struts dist and 
message-resources was
already configured there. As settings in web.xml will override settings in 
struts-config.xml, 
classloader can't find resource to be loaded and then you get that messages.
  Hope i helped you.

Kind regards,
 Daniel.

Re: [OT] [Reflection/Classes] doing something like instanceof at runtime

[Daniel H. F. e Silva]

Andrew,
  I don't know if this is the best way, but you can try something like that:

  boolean isInstanceOf(Object o, String klass) {
Class c = null;
try {
c = Class.forName(klass);
} catch (ClassNotFoundException e) {
   // TODO 
}
 
return c.isInstance(o); 
  }

 Daniel.

RE: Format a Date ?

[Daniel H. F. e Silva]

Hi Mahalkar,

  You can use JSTL to do that work on your JSP page. Just use formatting standard tags.
  As Mark said, it is piece of cake. 
  You can use:



  Formatting pattern is exactly the same as patterns used in SimpleDateFormat.
  Look at JSTL reference docs to more details.

 Daniel Silva

RE: Date format

[Daniel H. F. e Silva]

Hi all,

  Well, i recommend using JSTL tag formatNumber with type='currency'.
You can do this way:

  <%@ taglib uri="http://java.sun.com/jstl/fmt"; prefix="fmt" %>

  
  

  It worked for me.

Problems with Locale and MessageResources

[Daniel H. F. e Silva]

Hi all,
 I am needing help.
 I am getting in trouble with Locale and MessageResources stuff. When my JSP having a
 tag renders it is printing ???en_US.???. I know this 
is
because i configured 
  
 Well, i have a file with name ApplicationResources.properties located at 
com/sbpi/jsiw/resource
folder below WEB-INF/classes. So it is at my application classpath.
 I also have a file with name ApplicationResources_en_US.properties at that same 
folder.
 But i'm still getting ???en_US.??? stuff.
 I tried with Resin-2.1.9 and with Tomcat-4.1.24. It happens on both.

 Now tell me: what am i doing wrong?

Thanks in advance,
 Daniel.

Re: [OT] I'm tired of restarting tomcat!

[Daniel H. F. e Silva]

Hi Fabio,
 I know Tomcat is reference implementation and its license is great, but i can't loose 
my time
with issues like that you reported. So, i use Resin at my development environment. Let 
it take a
chance.
 But if you still prefer Tomcat, use 4.1.24. Maybe this issue was solved. I think 
4.1.24 is a nice
try!

RE: Does a degree matter?

[Daniel H. F. e Silva]

Hi all,
  Just my two cents.

  Craig's viewpoint is good for american-like degrees. But there are many different
education systems all over the world.
  For example, in my country (Brazil), Comp Sci bachelor's degree from public 
universities don't
teach nothing more than old theory. We study Automata theory, Graph theory, Calculus, 
Algebra, 
Physics, Statistics and Algorithms as course basis and we have specialized disciplines 
where we
study more specific theory like: DataBases theory, Operating Systems theory, 
Programming Language
theory, Compilers theory, Data transmission, Computer Networks, Computer Networks 
Management,
Artificial Intelligence, Functional programming, Logic programming, Object-Oriented 
programming,
Object-Oriented analysis, Project management, etc.
  And at my university (University of Brasilia) we have to take some optional (not so 
much)
courses to get our degree. They are: Management, Accounting, Economics, Sports, 
Political science,
Philosophy, English, Operational research, Law science etc.
  Our professors don't teach programming languages like Java, C, Pascal, Lisp, Prolog, 
FORTRAN.
They delegate this task to students.
  I think it is a hard course but it's worth it. 

Best regards,
  Daniel.

RE: [OT] BeanUtils property copying facility

[Daniel H. F. e Silva]

Hi all,
  I'd like to thank everybody for helping me. I think describe method will work.
But to that guys that said copyProperties would do the job i don't think so. Looking 
at code of
commons-beanutils 1.6.1 (latest available) i can't see that code working with 
destination bean
being a Map instance. Is my guessing right?

Best regards,
 Daniel.

[OT] BeanUtils property copying facility

[Daniel H. F. e Silva]

Hi all,
 Forgive me for posting an off-topic e-mail but i am needing help and as some 
contributors to
Jakarta Commons-BeanUtils read messages from this list i thought you could help me.
 Is there a feature in commons-beanutils where i can copy properties from a bean to a 
map
instance?

Best regards,
 Daniel.

Re: struts + resin

[Daniel H. F. e Silva]

Guys,
 I use Resin-2.1.8 and don't have problems. How are you deploying your application?
Could you post here problematic part of your resin.conf file?
Instead of configuring my application at resin.conf i put it at webapps folder and
configure my application in web.xml according to Servlets and JSP spec.
 This works for me in all cases.

Best regards,
 Daniel.

[OT]XML DOCTYPE question

[Daniel H. F. e Silva]

Hi all,
 This could be a dummy question but i didn't found any documentation talking about 
this issue. My
problem is:
 I developed an API that uses a XML configuration file. And i have also a DTD file to 
enable XML
validation. Then i generate a jar file containing my API and my DTD file. When running 
a test
application using my framework, JDOM returns follow exception:

org.jdom.JDOMException: Error on line 2: Relative URI "sql-map.dtd"; can not be
resolved without a base URI.

My config file has (at line 2):



 What am i doing wrong? Remember that my dtd file is inside my jar file. How would be 
an URI to
that?

Thanks in advance,
 Daniel.

RE: [OT] Which Object Relational mapping tool?

[Daniel H. F. e Silva]

Hi Jacob,
 You did a good point. I am working on a project and was in doubt about what use: pure 
JDBC,
DB Layer from iBatis or a real O/R mapping tool. I tested OJB, it is a great piece of 
software.
Looked at Hibernate, it seems like a good choice. I tested also Torque, what is as 
good as others.
 But, to my project i have choosed DB Layer from iBatis. But i am doing some 
customizations on it.
I am adpating it to use Jakarta Commons BeanUtils and, thanks to that, extending 
ResultMap
elements to enable dynamic ResultMaps using DynaBeans since there are moments where 
you can't
write 50 classes only to hold your results, or, you are lazy enough to write it.
 When i finish that modifications i will submit then to Clinton Begin, iBatis author, 
to receive
his agreement about that.
 If you have any cool suggestion about iBatis DB Layer, i'd like to hear it from you. 

Best regards,
 Daniel Silva.

[OT] Cayenne O/R Mapping Tool

[Daniel H. F. e Silva]

Hi all,
 I know this kind of question is done here almost every day, but i am still without a 
decision
about what O/R mapping tool to use. 
 I found Cayenne (www.objectstyle.org/cayenne). Did anyone here use it? 
 Pros? Cons?

Thanks in advance,
 Daniel.

And do Microsoft, IBM, Sun, Oracle, etc, give warranty about their products?

Well, so i have to praise the Lord for my boss. The cheaper the solution, the best it 
is.

[OT] Eclipse IDE - The Two Towers

[Daniel H. F. e Silva]

Hi all,
 I do appreciate all feedback posted here in this list.
 Well, i am only executing orders. I don't intend to obligate everybody to adopt my
recomendations.
My boss wants a standard environment to all developers. So, order is order.
 I think his concern about this task is to improve productivity. So, what is more 
productive?
 Following our discussion, does someone have experience writing Eclipse plugins? How 
difficult is
this kind of task?

Best regards,
 Daniel.

[OT] Eclipse IDE

[Daniel H. F. e Silva]

Hi all,
 I know that it is very possible that this subject was already discussed here, but i 
couldn't
search on archives (why is this resource disabled?).
 I'm beginning to design a software development process specification as a job task. 
It will
include, for instance, a list of all tools, software, frameworks, etc, necessary to 
develop
Web-based solutions in J2EE platform.
 And after doing a lot of research, i've found that open-source world has two leading 
IDEs:
Netbeans and Eclipse.
 I'd like to hear about experiences with both of them. In my preliminary tests i guess 
it was
difficult to work with Eclipse with focus on Web development. For instance, it doesn't 
have a cool
JSP editor like Netbeans. I've tried an Eclipse plugin, but its features are inferior 
than
Netbeans offered features.
 But i liked Eclipse's plugins feature. And it has a better aproach to manage code 
quality than
Netbeans.
 So, opinions?

Best regards,
 Daniel.

Re: Struts: a Graphic Artist blessing or curse?

[Daniel H. F. e Silva]

Hi Foong,
 After some headaches and some experience, i do the following:
  1 - We (developers and programmers) write a clear requirement doc about a graphical 
interface,
with all data that will be displayed, data type and this kind of stuff.
  2 - Our designers develop all graphical interface based on that requirement doc, 
using their
prefered IDE. Result will be pure HTML containing all data specified at requirement 
doc, but sure,
these data will be like "foo bar" data. Just necessary data to show all interface 
features will be
present. This process is a kind of pair programming (one graphical designer and one 
developer) to
guarantee that all requirements will be achieved.
  3 - We (developers and programmer), as we know HTML and as we developed together 
with designers,
integrate all real code to get all data that has to be showed.
 
  Well, i don't know if this is the best approach. But it have been working here at my 
job for a
long time. 
  Tips? New experiences? I'd like to hear about them.

Best regards,
 Daniel.

Design patterns book (was RE: DAO or ... ?)

[Daniel H. F. e Silva]

Hi all,
 An excellent book with clear examples is James Cooper's Java Design Patterns. You can 
find it in
PDF format to download here : http://www.patterndepot.com/put/8/JavaPatterns.htm
 I think it is much more clear in explaining patterns and its examples are very good 
to improve
learning patterns.
 I recommend it!

Best regards,
 Daniel Silva.

Unit testing a struts application

[Daniel H. F. e Silva]

Hi all,
 I am searching for possible improvements on my development process. One of greatest 
things i've
found is XP. I liked it very much. 
 One of XP rules is about unit testing. So follows my question : How can i unit test a 
struts app?
I heard about Cactus (another Jakarta project). Does someone here have experience 
using it? 
All kind of use cases would be a plus.

Best regards,
 Daniel.

[OT]Java rules engines

[Daniel H. F. e Silva]

Hi all,
 As we have here some of the best brains all over the world... ;-)
 I'd like to hear some opinions about java rules engines used in bussiness logic
validation. In my searchs at Internet i've found many, but i'd like to receive 
feedback about
them.
I've found many commercials (ILOG JRules, Blazer Advisor) and not so many open-sourced 
(Drools,
JEOPS, etc...).
 What do you think about them?

Best regards,
 Daniel.

Problemas with path attribute

[Daniel H. F. e Silva]

Hi all,
 I sent this question last week, but until now i didn't receive any reply. So i'll do 
it again.
My question is:
 I'd like to know why occurs an exception when i use path attributes like this one:
   path=/jsp/template.jsp?pageMenu=/jsp/menu.jsp&pageContent=/jsp/content.jsp
 Looking at struts DTD, i saw that path attribute is CDATA. So, why is it not accepted?
 Is this a struts bug or a xml parser bug?

 By the way, i'm using Struts 1.0.2.
 Please, i need help with this. 

 Thanks in advance,
  Daniel.

Problems with path attribute of element action in struts-config.xml

[Daniel H. F. e Silva]

Hi all,
 I am using Struts 1.0.2 at a business project. Problem is : i'd like to have path 
attributes
of elements action like this:
  path="/jsp/template.jsp?pageMenu=/jsp/menu.jsp&pageContent=/jsp/content.jsp"
 But i'm not having success on this. Why? At DTD i saw that path attribute is a CDATA. 
So it would
have to accept any kind of string, haven't it?
 
Thanks in advance,
 Daniel.

PS : Sorry for any english mistake, but english is not my native language.
