RE: Spring, myfaces, hibernate

[Jesse Alexander \(KBSA 21\)]

valid point. 1-pagers often grow to ugly multi-page 
spaghetti-apps...
 
introducing and therefor experimenting stuff like spring 
helps
tremendously... maybe spring is enough, 
tough

Currently, whenever connect to db to do something, I'm writing jdbc

And never use Spring.

Only 1 jsp page linked to 1 managed bean.

Is my approach alright? or something wrong?

RE: many facelets libraries

[Jesse Alexander \(KBSA 21\)]

hmm... try this link
 
Seems that the solution is to specify multiple libraries as a 
semicolon-separated list:

facelets.LIBRARIES  
  A semicolon (;) delimitted list of paths to Facelet tag libraries, 
  relative to your application's root. These libraries will be loaded 
  when the first request hits the FaceletViewHandler for page
compilation.

That kind of security is a wasp's

_javascript_ is not the only possible fountain of problems... 
SQL-Code-injection is another one...
 
My take is that JSF's validation might be already too far 
within the application's scope to deal with
such attack-oportunities. I would prefer to have it on a

  Users can type in _javascript_ and anything else. What is the security

RE: MyFaces + Weblogic = Classloading Problems

[Jesse Alexander \(KBSA 21\)]

The problem you mention (and the code you found) were 
needed  for WLS-versions
prior to 8.1.4 From that patchlevel on a patch has been 
added to WLS to fix the 
contextlistener-init problem.
 
I just deployed the MyFaces simple application (just had to 
remove the
description tags from the context-params, nothing else) as 
an exploded
webapp to the autodeploy directory. Every change to a 
jsp-file was immediately 
recognized and resulted in a different 
html-view...
 
Hmm... what could be the differences?
I use OpenSuse 10.0 (linux) and a 9.0 download from

Not really an idea what's happening... but maybe an idea how to find it
out...
Have you set the logging in MyFaces to the highest level?
MyFaces then logs the component-tree (with usefull info) to the log and
in
my components that tree-logging in restore- and render-phase have helped
my
a lot.

You can activate the logging by adding the correct log4j options...
in my xml-log4j-config I have these entries:

I often subdivide the managed beans in two groups:
- the usecase beans
and
- the model beans

I allow the usecase beans to depend on javax.faces.**.* classes but the
model
beans must be kept clean. The usecase beans are used to control the flow
within the usecase. The model beans are pure data-keeper.

It has worked in a medium-complex application, but I consider it as
"just
ONE working" model...

For this we request that all usecase-beans make requests from the
backend
(persistency,...) through facades. Those facades are not allowed to have
framework-dependencies. They use services, which depend on the 
backend-frameworks to get at the actual data. Usually they return 
the model-beans from above...

RE: Variable Resolver

[Jesse Alexander \(KBSA 21\)]

The stacktrace also talks about HtmlOutputLabel searching for this
property..

there is   in his jsp..

could it be that the labels bean (snippet from faces-config does not
contain that bean)
is also of class be.mnemonica.web.beans.LoginBean?
That would explain it clearly.

OR

He did send us the JSP the request is started from, but the problem is
only during
the rendering phase of the resulting JSP...

RE: Variable Resolver

[Jesse Alexander \(KBSA 21\)]

No need for the VariableResolver for such stuff...
As Volker pointed out, it depends on the getter/setter methods.

VariableResolver in ManagedBeans is only needed when you need to look up
some beans with which you basolutely no direct connection. I dare
to guesitmate that this will hit less than 1% of all JSF-applications...

FW: Any way to disable/sidestep converters/validators while processing a ActionListener event?

Subject: RE: Any way to disable/sidestep converters/validators while
processing a ActionListener event?

Hello:
 
We would like to be able to handle the ActionListener event
without converters
and validators (associated with fields on the form) generating
error messages.
When the form is submitted, we do want the field converters and
validators to 
generate appropriate error messages.  Is there a way to
disable/sidestep 
converters and validators while processing an ActionListener
event?  Further
details are provided below.

The situation:
--
1. Have a date input field
2. Have a link next to the input field that is used to set a
default value in the date field.
   An ActionListener is associated with the link.
3. When the link is clicked, the form is posted and the
ActionListener method is invoked.  This 
   method sets and default value in the date field and returns.
4. Since it is an ActionListener event, JSP redisplays the same
page.

A well known usecase...


Problem:

1. If an illegal date format has been entered into the date
field before clicking the link,
   the converter on the date field detects an error.  JSF
redisplays the page with the
   error message. 
2. Even if the date field is empty or has a legal value, other
fields on the form can have
   bad values such that their converter or validator will detect
an error.  Again, JSP 
   redisplays the page with the error message. 


UI Goal:  Have the link set the default value and ignore any
illegal fields on the form.
---   At this point in time, the user in interested in
defaulting the date field, not
  validating fields.  The fields will be validated when
the form is submitted. 


Current Solution:
-
1. The link has: immediate="true" set.
2. ActionListener associated with link runs early in the JSF
lifecycle. This method
   accesses the component and sets the date value by calling
.setSubmittedValue() 
3  ActionListener method then terminates JSF lifecyle
4. JSF redisplays page.  Since the date component's submitted
value has been modified, the
   default value now appears in the date field.

What we found is that some fields would not show the values the user had
entered before...


Why We are Looking for a Better Solution:
-
We have other situations where the ActionListener method needs
access to several fields
on the form. These fields are currently not available to the
ActionListener since it is 
invoked early in the JSF lifecycle.

If the converters/validators could be disabled, the
ActionListener method could run
at the normal place in the JSF lifecycle.  It is understood that
JSF could not do the data
binding for any fields where the converter fails.  But all other
fields would be properly 
bound and accessible to the AtionListener method.

You might have a look at the OptionalValidators described here:
<http://wiki.apache.org/myfaces/OptionalValidationFramework>

Comments, testcases and problem-reports are welcome.

RE: Howto add faces-config.xml file to /META-INF in a jar to create a deployable jsf component?

[Jesse Alexander \(KBSA 21\)]

The faces-config.xml in the META-INF directory is necessary to have
JSF automagically include your component in its runtime configuration.
The JSF-spec say, that every jar-file in the WEB-INF/lib directory of
a webapp is to be searched for a META-INF/faces-config.xml and if found 
the faces-config.xml is to be merged into the runtime config.

Hi List,

I have some problems to create a jar file which contains an
"out-of-the-box" usable JSF-Component.

I analyzed the jar-file from myfaces-all.jar and I noticed that you
put the tld and the faces-config.xml into the /META-INF directory of
the jar file. Is this step needed to let a servlet-container use the
component out of the box? So that you don't need to add the tld and
the faces-config of myfaces in the web.xml of your current project?
And how did you do this? I tried it the ugly way by creating a jar
file with Apache Maven and then using commands like "jar uf
mycomponents.jar META-INF/faces-config.xml" but this it not working
(Tomcat gives me a java.io.FileNotFoundException when it tries to
unpack the faces-config.xml and the webapplication is totally
unusable).

How can I create an out of the box usable jsf-jar-file with Maven?
What am I doing wrong?

To answer my own questions, immediate="true" on the "Save as DRAFT"
button means that it is processed before anything else, so the other
data isn't even available.  Explained in detail at
http://wiki.apache.org/myfaces/How_The_Immediate_Attribute_Works

It looks like I can do what I need by using
http://wiki.apache.org/myfaces/OptionalValidationFramework but
unfortunately that requires significant changes to all my forms that
need "save as draft" functionality.

RE: concurrency and t:dataTable (preserveDataModel, forceId, param)

[Jesse Alexander \(KBSA 21\)]

We solved the problem rendering an icon with a commandLink.
Then we passed the unique record id as parameter to the link, and in 
that way the backend was able to delete the correct record. It did not
need to
guess on the record using the relative position in the table, but hit 
directly the unique record-identifier.

Subject: concurrency and t:dataTable (preserveDataModel, forceId, param)

I'm trying to implement a simple DataTable with a button on each row.
A click on one of the buttons should delete the corresponding row item.
In a singleuser environment my application works as expected.
But up to now I haven't found a proper soultion for multiuser
environments.

The DataTable has a value binding to a list property of a backing bean.

...
   
...
The property getter getAllItems() queries the items list for example
from a data base. In a multiuser environment the getter getAllItems()
could return a different list every time it is called.


Now my problem:
In case the data base was changed since the last view rendering, the
method doDelete() is called on the wrong item object.

For example:
If I select item3 for deletion in my browser and someone else meanwhile
deleted itemx x<3, my submission deletes item4 instead of item3.


Approach 1: (cached items list, no refresh)
The property getter getAllItems() could query the list only once from
the data base and store the list in the session for further evaluations.
So I always delete the correct item.
But in getAllItems() I'm unable to decide when to update the stored
list. Therefore the stored list stays constant for the whole session
unless I update it manually.


Approach 2: (tomahawk preserveDataModel)
Using 
But the id attribute unfortunately has to be a static value.


Approach 4: (h:commandLink, f:param and getRequestMap)
When you replace the commandButton by a commandLink, you can add a row
specific parameter to the request. In the action method you can extract
the parameter from the requestMap and use it as item primary key.
Since commandLinks need JavaScript, this hack is no solution either.


I'm quite new to JSF and the problem seems very common to me, so there's
probably a simple solution. Please let me know...

Do you know the parent bean?
Do you know the id of the

 findComponent(java.lang.String expr) 
  Search for and 
return the UIComponent with an id that matches the specified search _expression_ (if any),

This method exists in UIComponent

RE: easiest way to get a jsf page as pdf download

[Jesse Alexander \(KBSA 21\)]

Reading this thread I came up with this idea:

Have the render-kit create a dom-representation of the UI-tree.
Then have a transform-mechanism convert it inot either html or pdf or wml, or...
according to the useragents needs or according to some other request-settings
that control the finaldisposition of the output

 Hi Hans,

What Matthias describes below is where you have a JSF page, and 
you want
a button labelled "generate report" or similar that creates 
some kind of
PDF document then serves it up to the user's browser. But that 
PDF isn't
"a picture of the current page", it's a PDF generated using 
data pulled
from a database or something like that. If that's really what 
you are
after then FOP is a good tool for that; your java code creates 
some xml
using the FO schema, then feeds it to the FOP library. Nothing 
to do
with JSF though.

There is no way to "generate a pdf that looks like my html 
screen" from
java code which I believe is what you want to do. Some browsers 
provide
a "print page" option, and some operating systems provide a 
"print to
PDF" option in the print dialog so that's one way of creating a 
PDF that
contains the current page but it's manual.

The FOP project is here:
 http://xmlgraphics.apache.org/fop/

 Hansjoerg,

we have worked with Apache FOP for creating pdfs. iText or
JasperReports are also lib that help you on that task.

inside of your backing bean method (referenced by a commandLink 
or
cmdButton) you can do somthing like this:

public String pdf() {

 FacesContext ctx = FacesContext.getCurrentInstance();

 if(!ctx.getResponseComplete()) {


 HttpServletResponse response = (HttpServletResponse)
ctx.getExternalContext().getResponse();

 byte[] file = //do some FOP, or ... stuff;

 response.setContentType("application/pdf");
 response.setHeader("Content-Disposition", "inline;
filename=\"foo.pdf\"");
 response.setContentLength(file.length);

 OutputStream out = response.getOutputStream();
 out.write(file, 0, file.length);
 out.flush();
 out.close();

 ctx.responseComplete();

 return null;
}


This will work in p(l)ain servlet or struts world too (expect 
of the
usage of jsf api (like FacesContext))

However, the *magic* here is the responseComplete()

Oh - and also that the user will never see any changes to the database
made concurrently by other users. That may be desirable, or maybe not.
Of course if it is desirable, then a read before each render has to be
done. 

However as you point out in (2), the model used for rendering really
does need to be preserved until the start of the next render phase for
consistency - and that saves one database read too.

I would love to see t:dataTable (and maybe h:dataTable) avoid fetching
the datamodel during validation when there are no input components in
the table; that would make a nice project for someone wanting to get
involved in MyFaces coding!

Ronald,

I want to virtual host so the path /hello maps internally to /hostname/hello.  
I'm trying to do some sort of internal

which would then include the relevant virtual

ViewHandler.createView(context, "hostname" + viewId) but that ALSO changes the 
submitted path to /hostname/whatever.jsf
instead of retaining it as /whatever.jsf.

Now, I'm thinking I can use the servletContextListener to put my own 
ExternalContext in there so when the JSP calls
ExternalContext.dispatch(), I can override that method to invoke 
"/localhost/filename" since I won't have a generic
"/filename" setup.

I'm open to new ideas and suggestions.  I wonder sometimes why I go for the

Hi David,

why you want to override - define your own in the web.xml !


myServletContextListener


You have to implement the 'javax.servlet.ServletContextListener' -
Interface with the following two methods :

public void contextInitialized(ServletContextEvent e);
public void contextDestroyed(ServletContextEvent e);

The same if want to listen for sessions. You have to additionally
implement the 'javax.servlet.http.HttpSessionListener'-Interface with

public void sessionCreated(HttpSessionEvent e);
public void sessionDestroyed(HttpSessionEvent e);

That is the idea of the jsf-comp-project ;-)
-> easy access to a repository and distribution plattform with less
   restrictive rules on licences in order to have more components for 
   users

@Cagatay Civici : If you want, just send me (or mike kienenberger) an email 
with your sourceforge-id, and we will add you to the project.


About Licensing:
If we do not distribute the JFreeChart-Library with the component and just 
document the dependency, would this make it possible to include the component?

This would mean that to build the component ee need a LGPL-library and the
end-user using this component also needs the jar-file.  But all the others can
also live without it.
After all our stuff also depends on the JDK and I do not think that is released 
with an apache(-compatible)-license.

RE: SQL paging with dataScroller

[Jesse Alexander \(KBSA 21\)]

No way that you need to resort to stored procedures...
 
It's just a bit nasty to do especially if you want to sort on every
column.
Basically the technique is about 20 years old.

You need a special datamodel, which stores the key-information of the
first and
the last record. 
When you need the next few records you make something like:

Select top AAA --column-names-- from table where (--your selection
criterias) 
and (key_column_1 >= last_key_column_1 and key_column_2 >=
last_key_column_2)

Hope you can see the pattern.

You have to resort to stored procedures to do paging with Microsoft SQL
server. This is an example:
http://weblogs.asp.net/pwilson/archive/2003/10/10/31456.aspx. 

 

Maybe you should consider MySQL? It offers a very convenient "Limit

Subject: RE: SQL paging with dataScroller

 

Paging at the database level is feasible sometimes natively but it
depends what you are using. For example, it's easy with Oracle but not
with SQL Server natively. However, that means that any changes in
sorting dynamically require reordering your recordset to output it
properly. 

 

In this case, depending how it's done, it could mean running the query
again with a different SORT clause, which means it could be pretty less
efficient than keeping a map/list of results in a "buffer" that you just
play with. But of course different cases call for different solutions.
Maybe you can elaborate a bit on what you want to do exactly and what
you need to provide (sorting, size of recordsets, etc...)?

 

If it applies, then I think it should be fairly easy to implement using
a datascroller that is plugged on a bean method that retrieves the
required data on get() probably? I've never personally done it but I
believe some people do it here.

Unless you're using some sort of substitution technology like

the refresh tag is a standard-html-tag:

Hi Andy

Have you thought about using the refresh-meta-tag?

You could render the page on first visit with a refresh header set to 1 second. 
The page would be rendered reading "--- please wait ---" and in the background 
initiate
a new request which then would build the connection, and render a new page...

A flag in the session could signal to your code whether the redirection is 
needed or not.

Advantages I see:
- standard request-processing
- the user would see the browser activity and could conclude: "ok, something is 
being 
  processed"

Andy,

There's many ways to do this.

Some ways you could do it:

1) Use the Shale ViewController stuff to define your backing bean to
be the controlling bean for your page.  It'd be able to receive events
like pre-render and post-render.

2) Create a phase listener that ran at pre-render and post-render phase.

3) Use a servlet filter -- this is how I manage my database
connections, but I have need for my database connection to be active
at all phases of JSF.

RE: Execute method automatically after page has been loaded and shown to user

[Jesse Alexander \(KBSA 21\)]

Hi Andy

Have you thought about using the refresh-meta-tag?

You could render the page on first visit with a refresh header set to 1 second. 
The page would be rendered reading "--- please wait ---" and in the background 
initiate
a new request which then would build the connection, and render a new page...

A flag in the session could signal to your code whether the redirection is 
needed or not.

Advantages I see:
- standard request-processing
- the user would see the browser activity and could conclude: "ok, something is 
being 
  processed"

Hi Mike!

I like the idea with the Servlet Listener,but I see one problem:
The database connection is already openened when the Application Server is 
started
-So could there be a problem with database connection timeouts? What happens, 
when the database returns a timeout.
-If no timeout happens, isn't it a bad approach to let the connection open all 
the time, because database connection are expensive as long as I know?

What do you think about my thoughts?

Andy

Andy,

There's many ways to do this.

Some ways you could do it:

1) Use the Shale ViewController stuff to define your backing bean to
be the controlling bean for your page.  It'd be able to receive events
like pre-render and post-render.

2) Create a phase listener that ran at pre-render and post-render phase.

3) Use a servlet filter -- this is how I manage my database
connections, but I have need for my database connection to be active
at all phases of JSF.

RE: myfaces in weblogic

[Jesse Alexander \(KBSA 21\)]

Hi Peter 

I think I read somewhere, that SP4 for WLS fixes the problem, that 
WLS initializes the Servlets before the listeners have finished.

That's why the MyFacesServlet explicetely can initialize
MyFaces in its init()-method. This Servlet is still in the 
MyFaces jar-files. It only changed its package-name.
-> org.apache.myfaces.webapp.MyFacesServlet

For the listener it could be something similar to the servlet:
repackaging...

RE: Re: MyFaces for production?

[Jesse Alexander \(KBSA 21\)]

Hi

just some figures from my profiling sessions for verification (meaning:
have sou seen similar/comparable numbers)

Application: VERY simple application (crossbar helloWorld) with no
business 
 logic, just one string attribute with a pure
getter/setter-access 
Servlet-Engine:  Tomcat 5.0
Hardware:IBM R50 laptop (1.5MHz Centrino, 1GB of memory)
Profiler:Yourkit 4.0
JDK: Sun 1.4.2
Usecase: results in 10 requests, 1 with a validation exception
Load:1 single user
Versions:
 - MyFaces   1.1.0
 - RI1_1_01


(all values in milliseconds)
Lifecycle-phase
State   RestApply   Proc.Upd.Invok Rendr  Total CPU
ViewReq.Valid. Model ApplResp
ms/Request
MF  Srvr   5010  10   10  0  32042
  Clnt  300  10   00 10  741   108
RI  Srvr 40  90  500 10  57077
  Clnt  711  70  40   20 20 1492   237 

retained memory after 10 requests
MyFaces Server: 64kB (4 kB in Session)
Client: 65kB (0.5 kB in Session)
RI  Server: 46kB (9 kB in Session)
Client: 29kB (0.5 kB in Session)

Size of transferred state-info (2 views...)
  welcome.jsf response.jsf
MyFaces (2Fields) 1836 Bytes  1532 Bytes
RI (1 Field)  1444 Bytes  1220 Bytes

Conclusions:
- MyFaces seems to be lighter on CPU (roughly 50% of RI)
- RI seems to be lighter on Memory (roughly 50-65% of MF)
- MyFaces-server-state produces a smaller session (roughly 50% of RI)
- RI-client-state transfers less (about 75% of MF)
- RI has less memory allocated outside the session (roughly 50-65% of
MF)

Unknowns:
- What happens with the memory-footprint when more than 1 concurrent
user 
  are producing load?
- How are the CPU-footprints when the views get more complex?

Comments/Ideas/Recommendations are VERY welcome
Alexander

PS: if someone creates a facelet-version of the sample-application I
would 
try to recreate the same measurements. Please contact me. The
Crossbar-
Application had to be changed to work with JSF 1.1!

Hi,

no performance measurement here - but 5 JSF intranet and 3 internet
applications deployed here on MyFaces, no problems with performance
whatsoever.

Interesting for the performance is the switch between client-side and
server-side state saving - client-side is better for memory,
server-side is much better for CPU performance!

an a number

My guess is that there is some deadlock in the app code, to my knowledge
MyFaces does not have any isse in this area.

RE: Using converters in non-JSF related code.

[Jesse Alexander \(KBSA 21\)]

Instead of subclassing it, I would "prefer" to delegate, that creates
two classes with a less tight coupling.

-Original Message-
There's not much in a converter and there shouldn't be any reason why
you couldn't do this.
However, since you're having to pass in a FacesContext and a
UIComponent, I think you'd have to reimplement a lot of unnecesary
support classes.

I'm not sure I'd stick it in a static utility method, but maybe that
makes sense in your use cases.

I'd probably go with a presentation-layer-independent converter class.
 Then subclass it to create the JSF converter.


When I look at my own JSF converters, this is a trivial refactoring. 
I've already got the non-JSF conversions being handled in separate
methods which are called by the getAs methods.

Sure you can do that.

someComponent.getChildren().add(anotherComponent);


Then you can either render the child-components yourself or let JSF do it:
getRendersChildren() is the key...

a corresponding log4j.xml to the classpath. This will dump you the

Do you want single regions of one image to call different methods
OR
Do yo want to have one image call one method. 

If it is the second, then you could render a commandlink and have 
an image as its child. That's the way you might do it in HTML.

Often thinking about how to do it in pure HTML (and posting that

Well... 

I see two alternatives:

1) We add one/two method to javax.faces.application.Application 
eg. getImplName() and getSpecVersion()
   But that would require a spec change...

2) We ask that at startup one of the implementation classes adds
   the information as a managedBean or a external-context variable
   This could be added also without a spec change, just need to
   agree with the RI-people on an identifier to use...

How to find out which implementation is running

Hi

When I want to write a component that must run under more than
JSF-implementation,
I often should know (runtime not development time) which implementation
is running, in
order to use the correct base-classes.

Has somebody devised a clever method to find out which JSF-runtime is

Or should we add something to enable this?

RE: Wizard app

[Jesse Alexander \(KBSA 21\)]

We use 1 managedBean per Wizard (not per page).

This bean manages the flow-control and cross-attribute validation. It

the final submit/validation is done, the service-layer is called to
persist.

All beans are session-context.

I can't belive, and so i checked again. The filter can be configured to
do PrettyPrint. and it works!

just put
  jtidy-r8-SNAPSHOT.jar and jtidyservlet-r8-SNAPSHOT.jar

and add

false!

RE: AW: FileDownload capability?

[Jesse Alexander \(KBSA 21\)]

-Original Message-
The content-length is passed in the response header. Therefore it cannot
be
set once you have written data to the response body (after all, the
header
is written before the body, for details see http spec). 

If you know the length in advance you should set it (for example when
streaming data from a file or from a BLOB field in a database). If you
are
generating data on the fly and cannot predict the length, simply do not
call
setContentLength. Your browser will still receive the file, it just
won't
show a download percentage as it does not know how much it will receive.
Try
it out with a few MB of data, you'll see what I mean.
-/Original Message-
The problem with the missing content-length is that certain browsers are
tempted to redo the request, just because the length is missing...
At least some reports on problems with double-requests from IE to PDF-
producing servlets imply this...

I think I have most of the answers to my own questions, after consulting
the O'Reilly book "Java Servlet Programming":

1. The response, if set, has to be exact.  However, it does not have to
be set.  Using it allows Servlets to be able to take advantage of
persistent connections, if available.
2. It must be set before sending the response body.

So, given this, does (2) above imply that, if done, setting the length
has to precede the first write?  Or it just has to be done before
calling responseComplete()?

In earlier examples, one had to call response.setContentLength() with
the number of bytes being passed.  I have the following questions
regarding this:

1. What are the consequences if I get the length wrong?  Does it have to
be exact?
2. Can the setContentLength() be called after I have done all the
writes, or must it be done before the writes?  If I can call it
beforehand, then I can compute the length as I go.  Otherwise, it will
be more difficult.

And it's even easier if one is generating a text file (rather than a

It is actualy much easier in JSF. You just need to have an action method
in
a (managed) bean, like this:


public String downloadFile() {
FacesContext facesContext = FacesContext.getCurrentInstance();
if (!facesContext.getResponseComplete()) {
String fileName = "myfile.pdf";

ServletContext servletContext = (ServletContext)
facesContext.getExternalContext().getContext();
String contentType =
servletContext.getMimeType(fileName);

HttpServletResponse response = (HttpServletResponse)
facesContext.getExternalContext().getResponse();
response.setContentType(contentType);
response.setHeader("Content-Disposition",
"attachment;filename=\"" + fileName + "\"");

try {
InputStream in = /* get your data */;
ServletOutputStream out =
response.getOutputStream();

byte[] buf = new byte[512];
int bytesRead;
while ((bytesRead = in.read(buf, 0, bufSize)) !=
-1)
{
out.write(buf, 0, bytesRead);
}

out.flush();
facesContext.responseComplete();
} catch (IOException e) {
throw new RuntimeException(e);
}
}
return null;
}


Then you can simply call the method from a commandLink or commandButton

OK

I looked into what JTidy delivers. Unfortunately it is not what we want
:(

The current jtidyServletFilter just VALIDATES the html and includes a 
validation-icon into the html-code delivered.The PrettyPrint feature is
only 
available in the full-featured jtidy.

What we could do is: Take the filter as a base and add the

Would that be enough? Or must we include an option to send it to the

if the parent component value is null since JSF won't execute
validators in that case.

a) value is null and foreign value is null
b) value is null and foreign value is not null.

c) value is not null and foreign value is null
d) value is not null and foreign value is not null

[Jesse Alexander \(KBSA 21\)]

Add a user-info-bean when
a) the session is created (Session-listener)
b) the user-credentials are created (by JAAS?)
and just display them from within the JSF-page...

Subject: User Management - advice needed.



 

Hello again.

 

My question is this.

 

I want when a JSF page is displayed, to look up the current user and
display some information on them.

For example...

 

<%

Principal principal = request.getUserPrincipal();

  String userName = principal.getName();

  User user = SomeUserManagementServerThing.loadUser(userName);

%>

 

<%=userName%>

<%=user.isAdmin()%>

 

The above code is fine for the old JSP/Struts way of doing thing. But
what is the approach I should take in MyFaces?

 

If the action method that makes the call to display the page knew about
the Principle I could pass the User object in and all would be great.

But I don't see a way for an action method to find out the currently
logged in user.

 

What do you guys think? Is a there a paper / tutorial already on this
that I've missed?

 

Thanks

Jeff

I only can say if speed is an issue, either move away from WTP based
plugins or wait for better times. To split the project into several
smaller subprojects and have ant doing the merge probably is the way to
go currently.

I cannot say how Nitrox behaves speedwise.
-/Original Message-
NitroX is no racecar. And I often have to use a "-clean" startup to
reset its internals...

But, to do justice to all tools, so far I have done no project
of a similar size with Exadel or any of the other competitors.

As for Eclipse itself, Eclipse unless you run it on a Mac is fast,
memory is the keypoint, you should give Eclipse more ram that its
standard settings would give it (which are around 64MB)

I usually start my Eclipses with following settings:
 -vmargs -Xmx512m -Xms200m -XX:MaxPermSize=200m
-/Original Message-
Generally Java loves and eats memory. I have no Eclipse-setup with less
than
768MB (both -Xmx and -Xms, I do not like the JVM to size up and shrink
its
memory footprint).

RE: SelectItems generation using Providers

[Jesse Alexander \(KBSA 21\)]

don't sound bad.

But you would use it in the SelectItems-tag.

If you want you can provide a first shot using the jsf-comp project (on
sourceforge).
CVS access is easier than sandbox-committer rights. But for easy
transfer to the 
sandbox/extensions everything must be apache-compatible (licenses...).
If you want
we can discuss it late night (mid european late night) on the myfaces
irc-channel.

Subject: SelectItems generation using Providers



Hi all:

I'm planning to adapt Providers framework
(http://providers.sourceforge.net/) to JSF.

Mainly, Providers could be used to generate SelectItems inside UISelect*
components.

 

For example, you could declare a hypothetical Providers bean in the
faces-config.xml like this:

 



  providers

 
ar.com.koalas.providers.jsf.ProviderFacade

  request



 

Use it from a JSP like this:

 


 

And let Providers generate a list of SelectItems to populate the combo
(or whatever other component could be) using a fixed value, JDBC, Spring
or POJO approach, or your custom one
(http://providers.sourceforge.net/examples.html)

 

Using Providers you can eliminate your backing beans getters to retrieve
SelectItems, and even reuse it from other beans/applications. 

A further step could be to standardize Providers by implementing JSR 227
(http://www.jcp.org/en/jsr/detail?id=227) for DataBinding.

 

What do you think about this? Would it be valuable or useful in JSF
world?

 

Thanks for your time.

 

Guillermo.

PS - The main problem that persists is that - if the user fills the

values will be empty when the user navigate from detail page to form1
again (don't know FOR SURE, but I think immediate="true" skips the

Thank you both for your support.
The point Jesse raised is cool, having a "optional validator"

requirements, but in this one, I think we'll go for something like
Volker said, because in the "details" page, our team saw that we don't
need any information from "form1" to add the details to validate. We
simply can add as much details as we need, go back to the form1, and
then use the "Complete Process" button to validate all form1 fields. 
 
Thanks again

Hello,

if i understand you correct, you need to execute

Have you tryed immediate="true", to skip both, in your

RE: [MyFaces] Custom Validator???

Hi,

we have the same problem. Mike and I are trying to do something in that
direction. For validators that do not take parameters, we have a 
solution. Currently we are trying to create a wrapper for validators
that allows to switch the validation mode from "hard" (Complete Process)
to "soft" (all errors are converted to warnings, processing continues)
or "none" (validation is ignored)

Search for "Optional Validator" in the mailing list archives...
or visit the jsf-comp project at sourceforge. Mike and hopefully me

my return from Italy) are also often on the MyFaces IRC-channel (20:00

Good morning everyone.
Thank you guys for pointing me out a good solution for the popup thing.
The current problem is something like this:

We developed a Wizard-Style to avoid the use of Popups. The flow
consists
in something like this:
form1->details->back to form1 to confirm the flow.
The main problem is that we need to go to the details WITHOUT validation
when the user clicks the "Go to Detail" button, but if the details are
complete
and the user clicks the "Complete Process" button, the form1 HAVE to be
validated.
 
Did I have to use/write a custom Validator component to addthis kind of
behavior?

multiple component jars

[Jesse Alexander \(KBSA 21\)]

Hi

I use some components from the tomahawk collection and have 
written my own components as well. 

Now I am in the process of packaging my own components into 
jar-files and have run into a nasty feature of the JSF
configuration. 
It is nice that each component-jar-file can have its own 
faces-config.xml and in that way add its components to 
the overall JSF runtime configuration. It is also easy
to replace a single renderer for a componen, just add
the renderer to the jar-file and "overwrite" the 
renderer-configuration in your own jar-faces-config. This
works great for renderers delivered by JSF itself. BUT as 
soon as I want to override a renderer from the tomahawk
components I run into troubles.

The config mechanism first inserts the standard config,
then adds the jar-faces-config and at the end adds the
configured (in web.xml) config-files. Unfortunately
there seems no way to specify the order in which the 
jar-faces-configs are added. Therefor its getting 
difficult to override single definitions (as described 
above) when having more than one jar with custom components.

How do you deal with that problem?

RE: Optional Validation Framework

[Jesse Alexander \(KBSA 21\)]

-Original Message-
Yes, we'll see...

it sure looks interesting!
-/Original Message-

It works and really solved our problem for our application. I just added
simpler version of the RequiredValidator(2).

I now will try to implement something for the other validators as well.
Our boss has licked some blood, now he wants more.

In the mean time I have made the jar-files (one for the runtime, one for
the sources) plus a small web-application (two war-files, one using
MyFaces
the other one using Sun RI) online at our sourceforge-site under the url
.

At our meeting we asked ourselves whether we are the only ones with this

problem:
On one form we have links that divert the usecase to some lookup-pages.
Upon return from there our users ask to see all data they have entered
before.
But the validation must not hinder them to jump to the lookup pages...
And for that problem we needed the optional validator...

Implementing the optionalValdiator I was a bit astonished to see that
the
MessageFactories for the validators are contained within
javax.faces.validator
but are incompatible (class-name and API) between the RI and MyFaces. I
sort of
had hoped that javax.faces... means compatibility...

Next steps will be
- trying to wrap the original validators within a
optionalValidatorWrapper
  -> in order not to have to reimplement all validators ourselves
- trying to add the possibility to specify custom error-messages per
  validator definition in the jsp-files

regards

Depends on what you need...

As long as you do not need calculations and lots of formatting 
(sort of exporting the "raw" data) you could construct a comma-separated
file and send that to the client. (if you specify the correct mime-types
excel will open automagically...) AND if the client uses ne of the 
real operating system (then ones without excel) he can open it with just
about every spreadsheet-application because CSV is THE universal 
format...
