JSF debugging

hi,
im new to JSF. i like it, but i wonder how to debug.
how do i find the exact line of code in a bean/jsp where the problem is?
eg i got a log like this (via log4j i did set debug-level for com.sun.faces to all ) - how do i find the jsp/bean that causes the error?
thx :)

hi;
you may use tomcat 5.5 and eclipse with JSF, its debugging features are quite usefull, but i should warn you that you may have to make some settings to enable debugging.

JSF debug output

we are using JSF on tomcat, integrated in JBOSS.
debugging is really horrible here - do you know, where i set debug levels or i can retrieve fine debug error message, also for JSF errors?
thanks in advance,
stefan

thanks a lot - with one of those links i could really find a good way to get detailed debug messages. i will explain it here again to help maybe other users that have the same problem:
1) search for file "log4j.xml" (e.g. jboss: server/default/conf)
2) add there two sections:
   
   
   
   <appender name="FACES" class="org.jboss.logging.appender.RollingFileAppender">
     <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
     <param name="File" value="${jboss.server.home.dir}/log/faces.log"/>
     <param name="Append" value="false"/>
     <param name="MaxFileSize" value="500KB"/>
     <param name="MaxBackupIndex" value="1"/>
     <param name="Threshold" value="DEBUG"/>
      <layout class="org.apache.log4j.PatternLayout">
         
         <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n"/>
      </layout>
   </appender>and some lines below:
   
   
   
    <category name="com.sun.faces" additivity="false">
        <priority value="ALL"/>
        <appender-ref ref="FACES"/>
    </category>
3) restart jboss / tomcat
the output will be in jboss' log directory, e.g. "server/default/log". feel free to change this to any location you want.

Turn on JSF debug mode

I see there is debug code in the JSF source code written by Sun. How is this activated?

After a quick scan of the code I only see 2 faults:
1) You declared the web.xml as servlet 2.4. It must be servlet 2.5 in order to use JSF 1.2 on JSP.
2) You're forgetten the f:view in your JSP page. Have you ever got a standard JSF page to run?

Log4j and jsf

I added log4j in my application. It is working and I can see my log.debug statements in the console. The problem is that I can see more than I want. My application uses jsf and Tomcat and I see many jsf debugs and I do not know what to change in my log4j.properties so as not to view them. My log4j.properties is the following:
log4j.rootLogger=debugLog, stdout
# CONSOLE appender
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{HH:mm:ss} %-5p %m%n
log4j.appender.debugLog=org.apache.log4j.DailyRollingFileAppender
log4j.appender.debugLog.Threshold=debug
log4j.appender.debugLog.layout=org.apache.log4j.PatternLayout
log4j.category.com.corejsf = debugLog
I tried to add something like the following
log4j.category.com.sun.faces = WARN
log4j.additivity.com.sun.faces=falsebut nothing changed.Any suggestions??

This is a log4j properties file problem. I'm not used to using the .properties file notation. I'm used to the XML notation for log4j.
Here's how I'd do it in XML:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'>
        
        <appender name="Appender" class="org.apache.log4j.ConsoleAppender">
                <param name="Append" value="true"/>
                <layout class="org.apache.log4j.PatternLayout">
                        <param name="ConversionPattern" value="%d{HH:mm:ss} %-5p %m%n"/>
                </layout>
        </appender>
        <logger name="my.java.package" additivity="false">
                <level value="debug" />
                <appender-ref ref="Appender" />
        </logger>
        <logger name="another.package.for.debug.level" additivity="false">
                <level value="debug" />
                <appender-ref ref="Appender" />
        </logger>
        
        
        <root>
           <priority value ="debug" />
           <appender-ref ref="Appender" />
        </root>
</log4j:configuration>This example will print to console only. If you want to print to a file instead, use the following lines (replaces the appender tags from the above example).
        <appender name="Appender" class="org.apache.log4j.DailyRollingFileAppender">
                <param name="File" value="filePath/FileName.log"/>
                <param name="DatePattern" value="'.'yyy-MM-dd"/>
                <param name="Append" value="true"/>
                <layout class="org.apache.log4j.PatternLayout">
                        <param name="ConversionPattern" value="%d{HH:mm:ss} %-5p %m%n"/>
                </layout>
        </appender>I don't know how you'd get both the console and the file appender working at the same time.
If you want further advice, or If you want advice on the .properties method of doing things, I suggest finding a log4j forum. The people there will undoubtedly have more experience and knowledge than us JSF nerds. =)
I assure you though, JSF is compatible with log4j. The log4j properties file just needs to be set up properly (more challenging than it should be, if you ask me).

A JButton, a mnemonic, and a missing action event.

Does anybody have a clue as to why a JButton, when activated by a mnemonic, would highlight the button onscreen but NOT call the button's actionPerformed() method?
Specifically, I have a (huge) application that consists of a main JFrame and any number of internal JDialogs launched (mostly) by buttons and menu items. The situation is arising when a dialog is closed without expressly placing focus on a component parented by the main frame. Once the dialog closes you can hit a mnemonic key combination and the button associated will 'depress' (turn grey) but not reset back to it's normal state, nor will the associated actionPerformed be called. A second usage of the mnemonic immediately following the first one WILL activate the button (and reset the visual state). This behaviour can be avoided by clicking on a component (other than a button) on the main frame before trying the mnemonic the first time, but that's not acceptable from a user's standpoint (this job would be sooo much easier without them! ;) )
I know it's not possible to get specific without code examples (which aren't possible because I can't narrow down were it's happening in the 900+ GUI-side scripts) but I'd really appreciate anyone who could point me in the right direction to start investigating this phenomenon. Thx.

Hi Yuki,
Yeah, after I turn on detail JSF debugging as instructed by the book Core JavaServer Faces, I figured out I had a validation error. That solves the mystery.
Thanks,

Missing Action Event from Custom Component

Hi JSF Gurus,
I have two custom components, both extends UICommand and have their
own renderers. I use them on two seperate pages, say component1 on
page1 and component2 on page2. And page2 is include inside page2.
I registered an action listener on component2. When the composite page
is rendered, I clicked on component2. However, the registered action
listener was not invoked. Inside the debugging (I'm using IntelliJ
IDEA 5.0) I set a breakpoint inside the decode method of Renderer2
(renderer for component2). I do see the componen2 actually as an
actionLister method binding being set to correct value. I do queue the
new action event to component2 at the end of the decode method. But
the action listerner never invoke.
Any idea what did I miss?
Thanks,
Edmond

Why can't I debug my JSF Portlet application after inserting an IFrame

Hi,
1) I created a jsf portlet application
2) I add a button in my jsf portlet application
3) I can debug my button's action method
4) Now I open my jsp editor and add an iframe
<iframe height="500" id="ifWindow" name="ifWindow"/>
5) I try to debug my button's action method but the debug cursor never reaches it like in step 3
6) I added a messageGroup but nothing appears there
7) I monitored "C:\Program Files\Sun\Creator2_1\SunAppServer8\domains\creator\logs\server.log" and nothing appears there
Is this a bug in Java Studio Creator or is there a problem with iframe in jsf portlet applications?
Why can't I debug a jsf portlet application if I put an iframe?
Has anyone got this to work in their jsf portlet application? What can I do to debug this simple application?
Thanks,
Marc

Hi,
I figured it out. I can debug my jsf application if I placed the iframe outside the <ui:form> element. If it's inside, I cannot debug the application. Are there any books or tutorials that I can read to get rules like this in JSF development?

Debug my jsf

hi
am developing my first web application in java using JSF/Hibernat/glassfish/Netbeans IDE i hope to find some way to debug my program during the execution and logging error messages
thank's for help

I don't see anything in that page that is particularly useful. Look for resources on how to debug using Netbeans, debugging a web/enterprise application isn't much different from debugging a regular client application. You set breakpoints and you let the code run by going to a specific JSF page. That will only properly work if the container (server) is executed from within the IDE itself so it can setup a proper link to the JVM debugging features for you.

URGENT: How to debug non-reproducable problem(s) in ADF JSF application?

This is one of the most anoying things in programing.... We have JSF application developed by JDev 10.1.3 and deployed on AS. It works fine but almost once or twice per day users complain that, say on a certain page (could be any page) they click on a button or a link and nothing happens. Sometimes it looks like the browser is trying to open a page but never does and sometimes the link or a button is dead. I looked into log file under opmn/logs and could not find anything?
This is very urgent, so please, please if you have any hint on how to approach this problem, let me know. At this time I cannot file the Service Request with Oracle since they would ask me to create sample code and reproduce the problem which is just not possible.
please help.

Hi,
if you are on JDeveloper 10.1.3.0 then chances are that these are concurrency issues. If a user starts a long running query then others may be blocked by this. This is fixed in JSF RI that is contained in JDeveloper 10.1.3.1
Its just a guess. To prove my assumption, make sure you run the app with a single seat and see if the issue reproduces or exclude queries from the tests.

Facelets and jsf-extensions problem.

I'm fairly certain I've run into a problem between facelets and jsf-extensions. I'm working with JSF 1.2 RI, Woodstock, Facelets 1.1.13, on Tomcat 6.
When trying to get Woodstock autoValidation to work I get a javascript error the "I has no properties". The error occurs in the com_sun_faces_ajax.js file in the jsf-extensions-dynamic-faces-0.1.jar (I've used both the RC4 and a build today ,10/18/07 from source with the same results). Here is the code snippet where it happens (with my comment).
var I = G.getElementsByTagName("components")[0];
var C = I.getElementsByTagName("render");
for(var F = 0; F < C.length; F++) {
In the second line there it looks like the variable I is null, but based on the post response below I don't know why.
The response from the post looks like this:
<partial-response><components><render id="PayableForm:vendorGci"><markup><![CDATA[{"valid":true,"id":"PayableForm:vendorGci"}]]></markup></render></components>
However the server side code (validation method) never gets executed. I'm willing to do some digging and debug work, but I'd need to be pointed in the right direction.
The following is more potentially useful code snippets.
Here is the textField code:
<w:form id="PayableForm">
<w:textField style="display:none;" />
<w:message for="vendorGci" />
<w:label id="vendorGciLabel" for="vendorGci" text="Vendor: " />
<w:textField id="vendorGci" autoValidate="true"
text="${vendorBean.searchGci}" maxlength="8" required="true"
validatorExpression="#{ vendorBean.validateVendor}" />
Here is the javascript in the page (the init function is called from the body: onLoad="setTimeout('init();', 0);" , this does happen):
<w:script type="text/javascript">
function VendorListener(){
function VendorNotify(props){
alert("VendorNotify called!"); <--------------- I never see this alert message
if ( props.id != "PayableForm:vendorGci") { return; }
var field = document.getElementById("PayableForm:vendorGciLabel");
field.setProps({
valid: props.valid
VendorListener.prototype.notify = VendorNotify;
function initAccountRows(){
var table = document.getElementById("PayableForm:vendorAccountTable");
table.initAllRows();
function init(){
initAccountRows();
var listener = new VendorListener();
dojo.subscribe(
webui.suntheme.widget.textField.event.validation.endTopic ,
listener, listener.notify);
Here is the validator method. It currently doesn't do anything, just trying to get something to work. I never see the output, and I never hit the breakpoint in the method.
public void validateVendor(FacesContext context, UIComponent comp, Object value){
System.out.println("**********************************");
System.out.println("validateVendor called");
System.out.println(value);
System.out.println("**********************************");
}

Actually I don't need a global variable. I need to refer in my included template the actual backing bean used in the current page. As all my backing bean extends a abstract class I could bind my component to a property of the current backing bean, no matters which one. Just like a polymorphic call but without the parameter. Let's imagine I could get this object of the facesContext object I would be able to do:
<rich:datascroller renderIfSinglePage="false" align="right" for="listagem" maxPages="12" fastStep="10"
pageIndexVar="pageIndex" pagesVar="pages" stepControls="show" fastControls="hide" boundaryControls="show"
inactiveStyleClass="paginacaoInativa" selectedStyleClass="paginacaoSelecionada"
styleClass="paginacao" tableStyleClass="paginacaoTabela"
binding="#{facesContext.currentBackingbean.formDataScroller}" id="paginacao">
Instead of pass the backing bean to the ui:param of this template... Dou you get the point?

Problem in JSF with Swing in a web application

hi
i am using jsf for my online projects.my problem is that when i use Swing concept ,the server is closed automatically when i click the swing dialog option 'OK', how can i protect server being closed automatically when user click the the options of Swing dialog box.it is so tedious because my application is going to integrate

Swing is GUI library for use in desktop applications.
JSF is a web application framework which runs on an application server and is accessed by clients via web browsers.
To fully understand what you have done, try accessing your application from a different machine than the server.
To answer your question, don't invoke System.exit() if you would like the process to continue. But that is the least of your problems.

Simple question about JSF configuration

I am using Tomcat 5.0 in Windows XP SP2. When I create a web application with JSF and put it into {tomcat_home}\webapps\, everything works perfect. But when I add a context path in Tomcat's server.xml such like
<Context docBase="C:\works\java_projects\jsf_test" path="/jsf_test" reloadable="true" debug="0"/>
And then I put same web application into this context path and try the url like http://machinename:8080/jsf_test/test.faces, it gives me exception as follow
I wonder if anyone knows about that? Thanks a lot!!

Check how your container loads the class.

How can I put an output stream (HTML) from a remote process on my JSF page

Hello,
I've a question if someone could help.
I have a jsf application that need to execute some remote stuff on a different process (it is a SAS application). This remote process produces in output an html table that I want to display in my jsf page.
So I use a socket SAS class for setting up a server socket in a separate thread. The primary use of this class is to setup a socket listener, submit a command to a remote process (such as SAS) to generate a data stream (such as HTML or graphics) back to the listening socket, and then write the contents of the stream back to the servlet stream.
Now the problem is that I loose my jsf page at all. I need a suggestion if some one would help, to understand how can I use this html datastream without writing on my Servlet output stream.
Thank you in advance
A.
Just if you want to look at the details .....
// Create the remote model
com.sas.sasserver.submit.SubmitInterface si =
(com.sas.sasserver.submit.SubmitInterface)
rocf.newInstance(com.sas.sasserver.submit.SubmitInterface.class, connection);
// Create a work dataset
String stmt = "data work.foo;input field1 $ field2 $;cards;\na b\nc d\n;run;";
si.setProgramText(stmt);
// Setup our socket listener and get the port that it is bound to
com.sas.servlet.util.SocketListener socket =
new com.sas.servlet.util.SocketListener();
int port = socket.setup();
socket.start();
// Get the localhost name
String localhost = (java.net.InetAddress.getLocalHost()).getHostAddress();
stmt = "filename sock SOCKET '" + localhost + ":" + port + "';";
si.setProgramText(stmt);
// Setup the ods options
stmt = "ods html body=sock style=brick;";
si.setProgramText(stmt);
// Print the dataset
stmt = "proc print data=work.foo;run;";
si.setProgramText(stmt);
// Close
stmt = "ods html close;run;";
si.setProgramText(stmt);
// get my output stream
context = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse) context.getExternalContext().getResponse();
ServletOutputStream out = response.getOutputStream();
// Write the data from the socket to the response
socket.write(out);
// Close the socket listener
socket.close();

The system exec function is on the Communication palette. Its for executing system commands. On my Win2K system, the help for FTP is:
"Ftp
Transfers files to and from a computer running an FTP server service (sometimes called a daemon). Ftp can be used interactively. Click ftp commands in the Related Topics list for a description of available ftp subcommands. This command is available only if the TCP/IP protocol has been installed. Ftp is a service, that, once started, creates a sub-environment in which you can use ftp commands, and from which you can return to the Windows 2000 command prompt by typing the quit subcommand. When the ftp sub-environment is running, it is indicated by the ftp command prompt.
ftp [-v] [-n] [-i] [-d] [-g]
[-s:filename] [-a] [-w:windowsize] [computer]
Parameters
-v
Suppresses display of remote server responses.
-n
Suppresses autologin upon initial connection.
-i
Turns off interactive prompting during multiple file transfers.
-d
Enables debugging, displaying all ftp commands passed between the client and server.
-g
Disables file name globbing, which permits the use of wildcard characters (* and ?) in local file and path names. (See the glob command in the online Command Reference.)
-s:filename
Specifies a text file containing ftp commands; the commands automatically run after ftp starts. No spaces are allowed in this parameter. Use this switch instead of redirection (>).
-a
Use any local interface when binding data connection.
-w:windowsize
Overrides the default transfer buffer size of 4096.
computer
Specifies the computer name or IP address of the remote computer to connect to. The computer, if specified, must be the last paramete
r on the line."
I use tftp all of the time to transfer files in a similar manner. Test the transfer from the Windows command line and copy it into a VI. Pass the command line to system exec and wait until it's done.

How to load a class dynamically (via reflection) in a jsf-component

Hi all,
I am writing my own jsf component and I would like to do it generically. Therefore I have an attribute, where the developer can pass a fully qualified classname, which I want to use to instantiate. But I have a Problem with the classloaders, everytime I get a ClassNotFound-Exception during debugging.
Does anybody know how it is possible, to to get the most parent classloader?
Currently I am even not able to load a class, which is in the same package like all other compontent-classes.
Thank you very much in advance
Thomas

Within web applications, I believe it is recommended to use Thread.getContextClassLoader(). Keep in mind that web applications require different classloader semantics than regular Java applications. The class loader which gets resources from the WAR is favored over others, even when this violates the normal class loading conventions.
