Re: some best practices questions

[bryan]

I myself get caching with hibernate which I am using for persistance 
but I wanted the more fine grained control like this so that I could page 
back and forth using displaytag.org. 

here is my jsp code for paging, hope this shows why I am doing it. I guess 
my code is more for implimenting a client view than for heavy duty caching.

snip=
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<%@ taglib uri="/tags/c" prefix="c" %>
<%@ taglib uri="/tags/displaytag-el-12" prefix="display" %>













=snip

Cause everything is cached it is a snip to move back and forth through
the records.

Re: OT/ Tomcat, Hibernate and MYSQL problem ( byte to blob )

[bryan]

I am using the following mysql driver 

-rwxr-xr-x1 Administ Aucun  321671 Jul  2 13:47 /c/bryan-website/jakarta
-tomcat-5.0.14/common/lib/mysql-connector-java-3.1.1-alpha-bin.jar

and it has worked fine for me previously .

I would carry out some checks on the struts action to verify the size
of the data.

Also check for the following

Re: [OT] Re: HTTP Compression

If only someone would do such a thing ! They would be rich beyond their wildest 
dreams. And they would probably use clustered linux servers in such a way that
they could retrieve such information in a fraction of a second. 

Results 1 - 10 of about 7,410 for compression servlet filter. (0.40 seconds)

Seriously... why do people keep replying to stuff that could just as easily be 
found on google ? 

I never ask anything on this list unless I'm certain that the answer isn't on 
google. 

Why do people keep replying to questions where the person asking
the question can't be arsed doing so and just wants someone else to write 
their code for them.

Re: Tool to convert HTML to Struts JSP's?

[bryan]

Your methodology is wrong. You should create the pages etc and the logic flow 
yourself throughout the application.

Use css for everything so that the designer can just give u a stylesheet. 

Use the tiles framework to use global templates.

Re: very dynamic forms

[bryan]

Wouldn't it be so cool if you could take something like a graph of
hibernate objects and
have a form dynamically generated for u.

With dhtml or something so that you could populate the whole graph in
one user form ?

For example a House object that had a set of rooms, each room with
it's own description.

The dhtm generated by the form could expand out so that the user could add an 
arbitrary number of rooms each with their own description. 

The whole thing could get filled out in a single http request. 

This would greatly reduce the use case for creating a house. 

Has anyone ever developed anything like this ?

Re: very dynamic forms

[bryan]

Just to clarify 

Struts can map form to dyanmic object . 

It would be cool if it could map to a graph of such objects. 

I know the functionality doesn't exist but I think it's a cool idea.

You could have a tag like this on the page. 



then an xml file like so 

  


  






and then you had a method that you could call 

ArbitraryForm arbitraryForm  = (ArbitraryForm) form;
House house  = arbitraryForm.deserialise(); // or whatever 
houseDAO.storeNewHouse(house);

I guess I just am in *love* with hibenate at the moment

using Pojo as actionForm

[bryan]

Ok , I admit I may have lost the plot somewhat/somewhere ... but am I
on the right track at all here ? Also I just signed up to the list and
caught the last post about VO but the answers aren't archived anywhere
yet. Would appreciate if someone forwarded me that conversation.

In my struts-config.xml file 


  


In my strutstestcase class  

ProfileDTO profileDTO = new ProfileDTO();

profileDTO.setUsername("bryanhunt");

BeanValidatorForm beanValidatorForm = new BeanValidatorForm(profileDTO);

setActionForm(beanValidatorForm);

actionPerform();

and in the action itself ... 

BeanValidatorForm beanValidatorForm = (BeanValidatorForm) form;

logger.debug(form);

WrapDynaBean bean = (WrapDynaBean) beanValidatorForm.getInstance();
logger.debug(bean.getInstance());

but the username field is null .. 

Am I on anything like the right path here ? I want to pass the POJO
straight to my service layer after struts validation. I know this
stuff has just been added in so I'm not really finding much
documentation on it.

If anyone can point me in the right direction I would be happy to add
a page to the wiki.

Thanks

Re: [OT] User Preference System Design

[bryan]

If you have a good learner and familiar with Dependancy injection/IOC
I would recomend you look at acegi.

It has a steep initial learning curve but there is no need that it
doesn't satisfy, I think it is the most flexible and advanced security
system/framework I've ever seen, providing security all the way down
to method invokations and object collection filtering.

It is 1000 times better than CMS ( although it does allow you to use
CMS as well ).

Re: Searching pattern/best-practise for forms

And if actionForms just used reflection ( to detect if there was a

to inherit from a base class you and everyone else wouldn't have to do
this ...

Re: Automatic logging

[bryan]

Incidentally I use a HUGE amount of AOP stuff and logging is the only
thing I am not using with it.

I use AOP for the following 

Declarative security management ( down to filtering returned
Collections by an ACL )

Declarative transaction management ( so that I don't have any
transaction management garbage in my code )

Automatically managing hibernate sessions.

In fact anywhere that you find yourself writing more boilerplate than
business code or repeating the same code again and again and again ...
you might find AOP saves you a lot of time and energy.

Re: Where to store and how to retrieve Images for web app

[bryan]

1) Store them to your relational database, 
2) Add oscache to your web application. 
3) Change your web.xml so that it contains the following filters.


CacheFilter
com.opensymphony.oscache.web.filter.CacheFilter



  CacheFilter
  /customer/displayImage.do


4) Now you have relational database storage, all the fun, and none of the pain.

5) You can configure oscache in a variety of ways, check out
opensymphony website/google for more.

Localize a dropdown select list

[bryan]

Is this possible with struts ?  i don't find a mention of it but can't
imagine it hasn't been implemented.

For example in the jsp 

 
   


Which generates the following ... 
type.yes
type.no
type.option_to_build
type.undefined

Is it possible to map type.no to a value in the resource bundles ??

If I were to speculate which would be more usefull to the community,
implementing something basic like this or creating support for JSF I
would imagine that this would
probably be more useful.

This reminds me of my skateboarding days, before learning how to do a
360 fakie kickflip it's kinda usefull to learn how to do an ollie

Re: OJB && struts

[bryan]

Spring makes it incredibly easy to work with hibernate, if you want to
switch to jdo or ejb3 at a later stage it makes it as easy as it could
possibly be.

There is a page on the hibernate site on the topic. 

http://www.hibernate.org/110.html

It also allows you to remove all your transaction code from your
classes and specify it in the xml file ( using wildcards )

Incidentally EJB3 is going to be largely based on hibernate and sun
have already signaled their intention that JDO and EJB are going to be
dropped and a new standard created most likely playing catchup with
Hibernate.

Using JDO just because it is a "standard" is a bad idea, I've been
there before and have difficulty trusting anything that gets designed
by some self interested group of big companies, usually so they can
make sure that your code only works with their libraries or IDE or app
server because at the end of the day you usually have to do something
that ties you to their implementation.

Runtime bytecode enhancement via cglib etc is the name of the game,
having to add another pre-processing stage to your development cycle (
as you must do with most implementations of jdo is s 2002 ).

Another thing EJB3 makes heavy use of IOC ( playing catchup with .NET
in this regard ),
if you don't "dig" IOC yet you need to start getting a handle on it
and Spring is probably the
best way to do this. 

Another thing .. once your using springframework with Hibernate for a
while you will sooner or later start asking yourself another question
... I'll leave it up to you to figure out what it is.

Bonne Chance

Bryan

Hey did you see Brady Hegberg's post for dynamic dropdown list's, I
reckon you'll like it as well,
also cross platform.


If you wanted to be a bit more ambitious you could also try implimenting

Re: EJB + Struts + Hibernate

[Bryan Hunt]

I don't believe it is unless you feel that the application will need to 
be distributed across a cluster.

I use the (excellent) spring framework ( springframework.org ) so that I 
can plug into a EJB layer if necessary in the future.

Re: EJB + Struts + Hibernate

[Bryan Hunt]

Spring is ultra cool. The most usefull thing that I'm doing with it is 
using it's built in hibernate support rather than creating 
and having to manage my own session factory code. It also allows u to 
manage your transactions in the xml config file
and use aspect oriented programming for stuff like security or 
performance monitoring the guy who started it is
called Rod Johnson and he's a real enterprise java guru.

It also allows IOC ( inversion of control ) which minus all the bullshit 
and hype words allows you to break your application
into really small completely independant components which allows you to 
really easily switch things like persistance layers,
unit test without loads of hassle, use mock objects during development 
etc etc.

Basically it turns everything into ultra loosely coupled beans
In short the struts --> spring --> hibernate works like a dream and if 
you don't like any component it is very easy to switch
them out.

I also tried using struts-config.xml using xdoclet. In the end it

yourself.

Some may say that it will be useful to generate the Struts form class 
and it's tags in struts-config.xml FROM the entity bean you just 
created. But ,tell me frankly, how many times we have forms that 
correspond one-to-one with our entity schema.

Use xdoclet only where it makes sense to use.

I don't see what advantage using XDoclet with Struts is? If someone 
can show me how it helps I'd love to see it. On this one project I 
inherited, it uses XDoclet with Struts and it makes things worse. For 
example, I like having a nice config file that I can modify 
(strut-config), yet with XDoclet, the struts config action mappings 
are generated by action mapping definitions defined at the top of the 
actual Action opbjects. That makes no sense to me. Now in order to 
change a return value, you have to modify source code versus just 
modifying a config file. I can see the benefit for XDoclet in other 
projects (ie EJB code generation) but for Struts I still haven't 
found where it helps, but I'm willing to be enlightened:)

Re: [OT] Anatomy of a long URL

[Bryan Hunt]

I know that the sun link does not authenticate your current client session.
I know that because I wanted to download the JDK for linux.
I wanted to download it directly to the server but they have that stupid
web page based download.
I got the whole url, ssh'd into my server and used wget to download it
in 3 minutes rather than in an hour on my dsl connection and then have
to send it to my server.
I think someone in sun just wanted to create something fancy regardless of
what the customers wanted just so he/she could put it on their cv.
I hate these long urls, they wrap right arround a ssh session and are very
unfriendly for people working with consoles.
--b
Daniel Perry wrote:
I dont think there is any information out there of the type you're
requesting (it's not really a 'pattern').
Long URLs are long because there is a lot of information to transfer.
The big long codes given in urls are often are often hashes (eg session
id!).  These are made long so that it's hard to randomly enter a code and
guess a correct one.
There's no reason to use long urls unless you have a reason! There are often
security reasons (eg hashes/tokens), where you dont want people to be able
to fiddle with the link.  take a bank for example - you dont want to
encourace hacking by putting:
viewtransaction.do?transactionId=18374
(of course i'm assuming that any actions such as these would check that you
own the transaction using session info!!!)
instead do somthing like viewtransaction.do?massive_code_here
and it instantly puts people off changing stuff.
As for suns example, i think sun counts you downloading stuff like J2EE SDK
as 'purchasing' it.  I think part of the reason for that link is to try and
stop anyone from downloading the file and "stealing" it!
Also bear in mind that places such as sun, amazon, etc have massive sites,
with many servers and an immense amount of information.  They need to be
able to track you, accross the site.  Some sites try and do this using big
codes that only the server understands, others tend to use nested
directories, eg:
http://news.bbc.co.uk/1/hi/world/middle_east/3845517.stm

Subject: [OT] Anatomy of a long URL
I'm not sure the subject of this email is indicative of my
question, but I have always wondered why amazon, sun, and some financial
institutions,
use long URL's for invoking actions. My only guess, since I've
only worked at small companies where all the applications pretty much
run on
one machine, is that the URL contains either encoded/sensitive
information or contains session information. I'm just wondering why
the heck does
it look so darn complex.
For example, I just downloaded Sun's J2EE 1.4 SDK
http://192.18.97.53/ECom/EComTicketServlet/BEGINjsecom16c.sun.com-
   

9660%3A40e01d9a%3A3099733a3e651ac9/-2147483648/428874567/1/483962/

th-JPR:1/j2eesdk-1_4_01-windows.exe
after the "/-" then there appears to be some random numbers delimited by
forward slashes.
Is this some technique for sharing sessions across different applications?
My apologies if this is one of those things that "everone" know's about
except me.
I really wasnn't sure how to google on this topic either, so if there is
some general
documentation I missed, please point me to it.

Ok, perhaps I didn't phrase that correctly.  Are there any tools that
allow one to validate a JSP.  I know that the resulting HTML 
depends on
the underlying java code and so validation is a problem, but I am
looking for something to make this easier.  I thought that 
perhaps there
was a better way than having to click through the app, saving the HTML
source for each page, then running through a standard validator.  Or
maybe this is just wishful thinking.
   

I typically validate the surrounding html, and hope that struts/jstl is generating good html. If it's not, then there is probably little I can do anyway.   I have also been known to employ a web crawling tool to crawl the site and save the pages to disk and then run validation on those pages.  It's a shell script I wrote though.

returning to the calling page

[Bryan Hunt]

Hi ,
I have the following action
http://localhost:8080/jestate-jsp/client-property-view-for-rent-action.do?id=1
On this page I have a form for adding a house to the shopping basket.
The shopping basket is displayed all the time on the left side of the site.
When someone calls this action ( client-add-to-basket.do ) I wanted the 
house
to be added to the basket and then have them bounce back to the original 
page.

I did try this approach 
if (mapping.getInput() != null) {
   //  return new ActionForward(mapping.getInput());
   return mapping.getInputForward();
   } else //we're fucked ! 
   {
   System.out.println("we're fscked ");
   return null;
   }

. but it didn't seem to work, I believe I would have to specify the 
input in the struts config
file and I intend for this page to be called from any page in the 
application.

Anyone got any suggestions ?

Re: Book recommendations

[Bryan Hunt]

I would suggest Struts , the complete reference by James Holmes.
It is incredibly clearly laid out and has a section on JSTL as well.
It is good as both an introduction and a reference.
Out of the last 5 tech books that I have bought ( not including
J2EE design and Development by Rod Johnson) it is the only
one worth the paper it was printed on.

Re: [OT] Speaking of "gratuitously difficult".....

[Bryan Hunt]

Forget about it, the only way to do it without tearing your hair out is 
to use ANT
and XDoclet.

J2EE is all about "wasting time on stuff that should be simple".
My 2 c, unless you need session beans it is better to use tomcat as your 
web container
and hibernate for persistance.

Use the spring framework for flexibility in case you need to change your 
mind later.

AHHGGG
I just want to deploy a simple war file.  I googled around and I could not even find 
good
documentation (Sun or elsewhere).
Does anyone know of a good plugin for Eclipse that creates war files?  I guess 
JBuilder has a good
war file creation utility.
Basically, shouldn't I be able to jar up everything in a webapp directory as long as I 
add the
correct "deployment descripter"?  I could not find an example of doing this.
Also, is it possible to create a war file that has a "context.xml" file?
I hate wasting time on stuff that should be simple.

Re: some best practices questions

[Bryan Hunt]

Sorry if this is considered spamming the list 
Speaking of storing stuff in session scope. I've developed what I think 
is a handy class which I think it useful for
when I want to store something like a search in a session variable.

For instance if I want to page through it ( using displaytags.org (10 
out of 10)) or simply if I don't want to fetch
from the database time and time again.
By default the data expires on an hourly basis. And if a different 
combination of parameters is sent it expires
the cached stuff.

Here is the class
snip=
package ie.jestate.struts.client;
import java.util.Date;
/**
* @author Bryan Hunt
*/
//TODO:Perhaps I should be generating a MD5 or something but I can't see 
a good reason to use any more CPU

public class HashGenerator {
  
   private StringBuffer buffer;
  
  
   /**
*
*/
   public HashGenerator() {
   super();
   buffer = new StringBuffer(50);
   // TODO Auto-generated constructor stub
   }

   /**
* @param urbanAreas
*/
   public void add(Integer[] array,String fieldname) {
   for (int i = 0; i < array.length; i++) {
   Integer integer = array[i];
   buffer.append(integer);
   }
   buffer.append(fieldname);
   buffer.append("-");
   }
   /**
* @param priceRangeStart
*/
   public void add(Integer integer,String fieldname) {
   // TODO Auto-generated method stub
   buffer.append(integer);
   buffer.append(fieldname);
   buffer.append("-");
   }
   /**
* @return
*/
   public String getHash() {
  
   //I append the hour onto the end of the string so that a hash will
   //only be good for a max of one hour.
   Date date = new Date();
  
   return buffer.toString()+ "-" + new Integer(date.getHours());
   }

}

Ok, tearing my hair out right now and extremely confused.
If you look at the Java Technology Forums you will see a rather nice 
little pattern that
someone called evnafets has created, it allows you to use a single 
Constants class
both in your Actions and in your JSP pages ...

It uses reflection to add it's static final members to a map which can 
then be accessed by JSTL like so


The address is 
http://forum.java.sun.com/thread.jsp?forum=45&thread=508847&message=2415101 


This works with a lot of stuff but the jstl and struts tags seem to be a 
little inconsistent in their behaviors.

For example this works ...

But for some reason ( my stupidity and the time of the evening ) I 
cannot get this to work.

or like this

I'm starting to feel like I'm back in my Perl days again  Is there a 
way that I can dereference these
beans or do I have to use sloppy string literals in my jstl code ?

Any suggestions or am I just stupid to want to do this ?

Hmmm, that gives me no error but no result either  I put in the

If I substitute the following line instead it works fine.

This line of code ...

Outputs
EMAIL_NOTIFICATIONS
on the screen.
I think this is starting to look like it just isn't going to work, I 
don't think that jstl is too smart about dynamic
variables like this. I tried the other suggestion as well (

c:set var="const" value="${scope['Constants']}"/>

)
But it didn't work either, this is starting to look as though it will be 
so convoluted that I might as well not be trying to use constants anyhow 
as I will have to look up the file anyway I might as well just use 
string literals. 

Cause it isn't scriptlet I wont get auto-completion anyhow. I'm going 
to try the suggestion from Rick Reumann and then I'm gonna throw my 
computer out the window.

In case anyone is still asking the original question that spawned this

probably is an alternative to Struts, not something you'd use with 
Struts.  At least, I've never heard of anyone doing that.

HiveMind is a piece of Tapestry which has been factored out and which 
more accurately "peers" to Spring -- although Spring has an MVC layer 
which "peers" to Tapestry and Struts.  Yes, confusing.  Still, I think 
at the level at which the original question targetted, a more accurate 
comparison would be between Spring and HiveMind.

I have no experience with HiveMind.  I've been pretty happy using 
Spring as a lightweight configuration management tool for wiring 
together beans at initialization time.

Re: some best practices questions

[Bryan Hunt]

The main arguments that people have against session storage is the following
a) Excessive memory consumption limits scallability.
True, just don't go crazy storing whole db's and stuff in there.
b) Sessions can not be shared by webservers in clustered environment.
Clustered webservers with shared sessions are such a myth/stupid idea.
Do it like hotmail.
   1) Request comes in to one of the front processor machines selected by
   DNS server with multiple resolves for the same address.
   2) Choose a machine that that has resources to spare.
   3) Users session is on that machine. The url for that machine is
   machine123.msn.com.
   4) User logs off, the next time they come back their session is on
   some other machine.
I fail to see what the point of sharing sessions between machines is ?
Even if the machine crashes, they just enter in the initial address (ie
hotmail.com ) and get sent to a working machine.
So my point is ... what's so bad about sessions ? 

Also if session ties you to a machine then file storage is twice as bad.

I have an idea how to persist the data that I currently place in session
scope but I need to run it by someone.
Recall when I said that placing data in session scope is frowned upon by
some members of my team? Well no one said anything about not using Java
serialization. Why couldn't I serialize the 
same data that I currently keep in session scope? I've already
implemented a solution for streaming images so creating a temp file
should not be a problem. Here is what I think I will need:

In the action where the data is first retrieved:
 try {
  final String prefix = "myVehicleLineMap";
  final String suffix = null;
  File file = File.createTempFile(prefix, suffix);
  FileOutputStream fileOutputStream = new FileOutputStream(file);
  ObjectOutputStream objectOutputStream = new
ObjectOutputStream(fileOutputStream);
  objectOutputStream.writeObject(myMap);
  objectOutputStream.flush();
  myForm.setTempFileName(file.getAbsolutePath());
 } catch (Exception e) {
  System.out.println(this.getClass().getName() + "==>> " +
e.toString());
 }
In the action where the data needs to be re-accessed to prepare the page
for re-display:
 try {
  FileInputStream fileInputStream = new
FileInputStream(myForm.getTempFileName()); 
  ObjectInputStream objectInputStream = new
ObjectInputStream(fileInputStream); 
  SortedMap myMap = (SortedMap) objectInputStream.readObject(); 
  // use myMap as before (when in session scope)
 } catch (Exception e) {
  System.out.println(this.getClass().getName() + "==>> " +
e.toString());
 }

This is just an idea at this point, so I would welcome any feedback. I'm
not sure if this will work or if its feasible, but at least it may
generate some more ideas.

You need to have all your Constants in a Map that is in application 
scope.  Kris Schneider posted this great piece of code to add to your 
Constants  file to return all your constants as a Map. At app start up 
I have a  servlet that does several things, one of which call the 
properties method  to put all the stuff in a Map and then you can just 
put that in scope:

//in some servlet at startup:
ServletContext context = contextEvent.getServletContext();
context.setAttribute("CONSTANTS", UIConstants.getConstantsMap());
(Below you don't need to do like I have. I had other reasons to do it 
this  way at the time. But just provide the getConstantFieldsAsMap() 
method )

//example class: UIConstants
private static Map constantsMap;
static {
constantsMap = getConstantFieldsAsMap(UIConstants.class);
}
public static Map getConstantsMap() {
return constantsMap;
}
//all your constants:
public final static String WHATEVER = "whatever";
//this does the work.. thanks Kris
private static Map getConstantFieldsAsMap(Class cls) {
Map propMap = null;
try {
Field[] allFields = cls.getDeclaredFields();
int numFields = allFields.length;
propMap = new HashMap(numFields);
for(int i = 0; i < numFields; i++) {
Field f = allFields[i];
int mods = f.getModifiers();
if(Modifier.isPublic(mods) && Modifier.isStatic(mods) &&  
Modifier.isFinal(mods)) {
String name = f.getName();
Object value = f.get(null);
log.debug("Putting name = " + name + " and value=" + 
value  + " into propMap");
propMap.put(name, value);
}
}
} catch(IllegalAccessException ie) {
log.error("Problem loading constantFieldsAsMap " + ie);
}
return Collections.unmodifiableMap(propMap);
}

//end class

Hi list,
I am coding an app where I rely on a background service to check regularly
for new mail. I want to instantiate my service component (the one checking
for mail) when the context is loaded and have it running in a background
thread. I have done only very limited coding with threads so far :(
What I plan to do is to create a controller servlet that is loaded on
startup and that creates instances of all my services. All services extend
Thread and are started by invoking the run() method when the controller
servlet starts. Would that work? How would I then set the intervall on which
my mail service checks for new mail? Could this be done using
sleep(interval)?
I wonder whether anyone has tips on this for a newbie or if there is such a
thing as a best practice on this.
TIA, Jan

I dunno, it's a good product and I really like it but I've never seen 
any awareness of jsp editing.

I've been using it for a while now as well.
And cause it hasn't ever indicated that it understands scriptlets I've 
never used it for debugging.

Then again, I'm aiming for zero java code in my jsp's.

Re: Tiles, Validation and reuse of HTML Form

[Bryan Hunt]

I do it with a seperate action for each use case. I find it tedious but 
have not found a better way.

Josh Holtzman wrote:
Hello All,

I've tried to search the list archives for previous threads on this topic,
but it appears the search feature is not working.

We are building a simple website that offers about a half dozen products for
sale. 


We have one dedicated page layout (the product page) that contains a photo
and description of the product.  On this page there is also a list of the
other 5 products.  By clicking on any one of these products, the page is
refreshed, and the new product information appears in the same layout.  Also
on this page is an HTML form that is used to add items to the shopping cart.
From this form a user can choose any one of the 6 products from a select
menu, type a quantity, and submit the form.. To add items to the shopping
cart.  This form is the same on all the product pages.

For the sake of GUI reuse and maintenance, we have implemented the site with
tiles.  For this particular page we have created a base template named
"website.product" containing the header, footer, body layout, and html form
tiles.  For each of the 6 products we have extended this base template, and
added a tile with the product photo, description, and price.

In the struts config file we created an Action element for each of the 6
product pages.  For instance:


path="/products/lazydazy"
  parameter="website.product.lazydazy"
  scope="request"
  type="org.apache.struts.actions.ForwardAction"
  validate="false">


And


path="/products/sallysue"
  parameter="website.product.sallysue"
  scope="request"
  type="org.apache.struts.actions.ForwardAction"
  validate="false">


The following is our dilemma:

We are using the same tile containing the html form (which we declared in
the base template) for all these pages.  This doesn't present any problem,
except when validation fails.  When the validation fails, Struts must
determine which page to return and display the error message.  But our
problem is, the Action element requires we specify a single location.


path="/addtocart"
 input="website.product.lazydazy"
 name="addToCartForm"
 scope="request"
 type="com.americandatacorp.struts.action.cart.Add"
 validate="true">
 


But if an item is added to the cart from the "website.product.sallysue"
template, and validation fails, the user is returned to the
"website.product.lazydazy" page with the error displayed.

Does anyone have any suggestions, other than having to create a seperate
"addtocart" action for every page?

Thank you for your assistance in advance.

Re: Hibernate

Hibernate = persistance
Struts = presentation
This question = Hibernate forums http://www.hibernate.org
Your answer = No, the size of tables will not be a problem

Hi,
I have just completed my application using Strut.
I have gone through some of the e-mails talking about Hibernate.
In my further enhancement of my application i want to use some object

Has anybody used Struts with Hibernate?
Did anyone faced memory problem related to Hibernate.
I have got tables which have got more then 10 million records.

Re: OT/ Tomcat, Hibernate and MYSQL problem ( byte to blob )

My app is able to do it no problem, back and forth.
You can get the source code from http://jestate.revoltingdigits.com/

My code is a  mess at the moment but that code is working.

I wouldn't use DBCP though as Gavin King is apparently fed up with it,

POSSIBLE OT: localised hashtable custom tag question

[Bryan Hunt]

Ok here's the scenario 
My (opensource) application is going to be available in the users
language.
All my struts localisation stuff is working fine, all the labels and
stuff are stored in property files etc.
I am using hibernate for persistance.
JSTL does not allow you to call functions on objects.
It only allows you to access the properties of beans. ie you cannot
do ${object.getDesctription("fr")}
One of my hibernate POJO's house has got a hash of descriptions inside it.
The descriptions are going to be referenced by java.util.Locale objects
The reason is so that the description of the house itself is going to be 
localised.

--
So what I want to do is either create or use a tag which will allow me 
to do the
following.


or



The tag will then access the struts session and see what Locale the 
person is
using.

If there is a description that matches that locale it will be outputted ,
if not the description matching the default locale will be used.
Perhaps I am looking in completely the wrong direction.
If I am being stupid here please feel free to alert me
I've been trying to decide the best approach for about 2 weeks.
I don't really think this belongs in the DAO or hibernate layers
as it is kinda a presentation issue.
Is anyone else working with something similar ? Or do I have to
build up a tag lib from scratch ?
Thanks
Bryan

For example a House object that had a set of rooms, each room with
it's own description.
The dhtm generated by the form could expand out so that the user 
could add an
arbitrary number of rooms each with their own description.

The whole thing could get filled out in a single http request.
This would greatly reduce the use case for creating a house.
Has anyone ever developed anything like this ?

struts file upload strange error

[Bryan Hunt]

Hi there list,
I have been trying to get the most simple file upload example working with
and have been receiving a strange error message that I just can't seem 
to shake.

Here is the basics of my action form
snip=
public class ImageUploadForm extends ActionForm {
   // - 
Instance Variables
   /** imageFile property */
   protected FormFile file;

   // - Methods

   public ActionErrors validate(
   ActionMapping mapping,
   HttpServletRequest request) {
  
   if(file == null){
   System.out.println("file is empty");
   }
   return null;
   }

   public FormFile getFile() {
   return file;
   }
   public void setFile(FormFile file) {
   this.file = file;
   }
=snip
Here is the basics of the action
snip=
public ActionForward execute(
 blah) {
   System.out.println("at least i managed to get called");
   throw new UnsupportedOperationException("Generated method 
'execute(...)' not implemented.");
   }
=snip

Here is the basics from my struts config file
snip=
   
   
   

   attribute="imageUploadForm"
   input="/form/imageUpload.jsp"
   name="imageUploadForm"
   path="/imageUpload"
   type="ie.jestate.struts.action.ImageUploadAction"
   scope="request"
   validate="true"

sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
=snip
I have tried changing the type to text and the type to String in 
the form and that works but use this FormFile class and everything 
seems to go fubar. 

It never even gets to call the action , instead it generates this error 
message ,
but the setters and getters are right and the variable is public, this 
only happens
with the FormFile. All the struts stuff is in my classpath as is 
commons-fileupload-1.0.jar.

Anyone got any idea what the hell I'm doing wrong ... I'm starting to 
suspect this
could be a struts bug cause everything looks straightforward enough.

Re: background process

[Bryan Hunt]

If it's unix that you are running on you could run a command using 
"nohup" , the java orthodox way
is to use a message driven bean/jms if you are running inside an 
applicaion server such as JBoss.

Re: Cancel button and security

[Bryan Hanks]

You are absolutely correct Przemyslaw. Realizing that
form validation is cursory at best and easily bypassed
at worst is a good approach.

One of the hard-learned lessons that (it seems) few
developers get is that _ALL_ data received from the
user is suspect, not only in content but in type.  For
example, code that suffers from SQL injection
vulnerabilities is written by people who don't
understand this concept.

I still use the validator as a first line of defense,
because it is quick and (relatively) easy to implement
and the response time is quicker for the user, however
all data gets the final validation check by the
model/business logic layer (with the appropriate
exception thrown if invalid).

Cheers,
Bryan Hanks

Date:   Fri, 15 Jul 2005 08:01:15 +0200

Hello,

Many developers use tag  to perform
action without 
validation
(and for other reasons). It's usefull but it can be
danger because of
security. If we don't serve cancel button in every
Action or BaseAction 
then
it's possible to perform some actions without
validation.
How?
It's very simple. Just putting parameter in url
org.apache.struts.taglib.html.CANCEL=1 or adding form
element
.

I've tried this trick in many sites written in Struts.

I advise to remember about this problem if we don't
have a validation 
in
business layer.

Re: passing objects from one request to another

[Bryan LaPlante]

my output stream has to be controlled by my action class. It is an ajax
integration for http://www.xoscript.org
where you can invoke methods on a POJO class and in turn that class can
include the output of another action as it's return value.

Re: [OT] Java Hosting Providers, yes, I know it's been brought up before on the list.

[Bryan LaPlante]

I feel your pain guys. I found a provider that made me wander why more of
them don't do this. http://www.eapps.com you get a virtual machine running
Linux for each domain and one of the most comprehensive control panels I
have ever used. 20 bucks a month gives you a fair amount of features and
space.

My 2 cents

Re: of a header gives an SSL exception?

[Bryan and Angela]

If you look at the exception, it is saying that you are having a PKI 
configuration issue.  It looks like you do not have your Certificate 
Authority (CA) configured.  Your error appears similar to this error: 
http://forum.java.sun.com/thread.jspa?threadID=573918&tstart=60

You need to have some understanding of your PKI setup to fix the issue.  I 
didn't see what version of Tomcat you are using, but here is a guide: 
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/ssl-howto.html

Hope that helps.
Bryan

Simple. But when it loads as part of my 'ui' app I get this:
javax.servlet.ServletException: Exception opening resource 
https://1.2.3.4:8443/ui/includes/header.jsp: 
javax.net.ssl.SSLHandshakeException: 
sun.security.validator.ValidatorException: PKIX path building failed: 
sun.security.provider.certpath.SunCertPathBuilderException: unable to 
find valid certification path to requested target

I can see that SSL is involved, but I was able to get past the login 
pages etc so I don't understand what Struts/Tomcat is trying to tell me 
here; any advice?

If it helps, I can load https://1.2.3.4:8443/ui/includes/header.jsp 
manually just fine.

Re: XDoclet

[bryan ( [EMAIL PROTECTED] )]

my personal opinion

XDoclet is on the way out and 1.5 anotations will replace it. 

I never liked it anyway. 

It does not work in a pleasant fashion with struts config files.

Their is no real advantage in learning it as ejb and hibernate will
both use anotations.

I don't know why someone would generate their spring config with xdoclet.
