Problems in JSF t:commandlink

Hello,
I am facing a problem with JSF Command link
I have three JSP pages with one backing bean in session scope.The property defined in the backing bean is an Object type which contains fields mapped to the database.
The navigation between pages is through hyperlinks.
I enter data on page 1 and move to page 2.Again due to some reasons if I come back to first page I dont see values restored on the textfields on page 1.It is again reset when page 1 loads.I have to restore values and I have to do it using command links.I do not want button to navigate between two pages.
How can I restore data
I set the data on textfields as #{BackingBean.property.property_field}
I am new to JSF.can anyone suggest how to restore values while navigating.
[email protected]
Thankyou,
Pankaj Shirke

on the commandLink tag are you using the immediate = "ture" if so remove it or set it to false

Very big problem with JSF about FORM and "id=" for HTML form's elements and

I have discovered a very big problem with JSF about FORM and "id=" for HTML form's elements and java instruction "request.getParameterNames()".
Suppose you have something like this, to render some datas form a Java Beans :
<h:dataTable value="#{TablesDb2Bean.myDataDb2ListSelection}" var="current" border="2" width="50%" cellpadding="2" cellspacing="2" style="text-align: center">
<h:column>
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
<h:outputText id="nameTableDb2" value="#{current.db2_name_table}"/>
</h:column>
</h:dataTable>
Everything works fine...
Suppose you want to get the name/value pairs for id="nameTableDb2" and #{current.db2_name_table} to process them in a servlet. Here is the HTML generated :
<td><span <span class="attribute-name">id=<span class="attribute-value">"j_id_jsp_1715189495_22:0:nameTableDb2">my-table-db2-xxxxx</span></td>
You think you can use the java instructions :
Enumeration NamesParam = request.getParameterNames();
while (NomsParam.hasMoreElements()) {
String NameParam = (String) NamesParam.nextElement();
out.println("<h4>"++NameParam+ "+</h4>);
YOU ARE WRONG : request.getParameterNames() wants the syntax *name="nameTableDb2" but JSF must use id="nameTableDb2" for "<h:outputText"... So, you can't process datas in a FORM generated with JSF in a Servlet ! Perhaps I have made an error, but really, I wonder which ?

While I certainly appreciate ejb's helpful responses, this thread shows up a difference in perspective between how I read the forum and how others do. Author ejb is correct in advising you to stay inside JSF for form processing if form processing is what you want to do.
However, I detect another aspect to this post which reminds me of something Marc Andreesen once said when he was trying to get Netscape off the ground: "there's no such thing as bad HTML."
In this case, I interpret ungar's request as a new feature request. Can I phrase it like this?
"Wouldn't it be nice if I could render my nice form with JSF but, in certain cases, when I REALLY know what I'm doing" just post out to a separate servlet? I know that in this case I'll be missing out on all the nice validation, conversion, l10n, i18n, ajax, portlet and other features provided by JSF".
If this is the case, because it really misses the point of JSF, we don't allow it, but we do have an issue filed for it
https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=127
If you can't wait for it to be fixed, you could decorate the FormRenderer to fix what you want.
I have an example in my JSF book that shows how to do this decoration. http://bit.ly/edburnsjsf2

Problems with JSF and included subviews

Hi everybody,
I' ve got a problem with JSF and included subviews which makes me going
crazy. I've got no clue why my web-pages are represent wrongly. The only
tip I've got is that it must be connected with the kind I do include my JSF-pages.
When I use <%@file="sub.jsp"%> my pages are are represent right. When I use <jsp:include page="Sub.jsp" /> or <c:import url="Sub.jsp" /> ( mark: the usage of flush="true" or flush="false" doesn't matter )
my pages are represent wrongly.
The usage of tags like f:facet or f:verbatim were also included but didn't point to an solution.
I searched the whole Sun Developer Forum and some other web-sites for any solution for my problem but the given hints and clues didn't help. Now I'm trying to post my problem directly in Sun's Forum in hope to get help.
My environment is the following:
JAVA JDK 1.5 Update 4
Tomcat 5.5.9
JSLT 1.1
Sun JSF 1.1
Win 2K

Hello Zhong Li,
many thanks for your post, but it didn't work.
My problem is that the JSF-Components im my included or imported
JSP-Pages does not accept any kind of style or styleClass for
designing. The components take over the informations for colors
but not for alignment.
When I take a look at the generated JAVA-Source in $TOMCAT/WORK/WEBAPP for my sub.jsp ( sub.java )
it seems that the resulting HTML-page would be presented correctly.
But later when I start the application via Firefox or Mozilla the html-sourcecode is totally wrong.
In my example I create a simple grid with 2 rows and 2 columns.
Both columns contains JSF-Outtext-Components and are included with div-tags.
The generated Sub.java shows that the text would be setted in the div-tags. Unfortunately the html-sourcecode represented by my browser shows that jsf-text is not setted in the tags but in the <h:form> tags. The div-tags are neither rounded by <h:form> nor containing the JSF-OutText-Components.
Any clue?
Many thanks Benjamin

Navigation Problem in JSF - Urgent, pls help

hi,
I have a problem while navigating into a popup using a custom commandLink which opens the popup.The problem is that when i close the popup and return to the parent JSF and click any button or link in the parent, the page navigates to the page that was shown in the popup. This is my custom component:
<hl:helplink id="alternateIdHelpLink" rendered="true" actionListener="#{helpBean.handleEvent}" value="Help" action="helpNeeded" target="NewWin" onclick="javascript:openPopup();"></hl:helplink>I have specified the navigation 'helpNeeded' inside the faces-config file which navigates to the page that is shown in the popup. So the problem is that i am unable to navigate to any other page after i open the popup(even after closing it).Can anyone pls find a solution for this problem.
thanks and regards
soorejkumar

Thanks Sergey.Smirnov for the code..but its not working :-(...
This is my javascript for opening the popup in my help.js file:
function openPopup() {
var windowDefn = "width=800, height=400, location=no, menubar=no, status=no, toolbar=no, scrollbars=no, resizable=yes";
win=window.open('',"NewWin", windowDefn);
}On clicking the Custom Command Link the popup is opened. But then when i return back to the parent and click any other link or button the contents inside the popup is being displayed.
<hl:helplink id="alternateIdHelpLink" rendered="true" value="Help" onclick="openPopup()" action="#{helpBean.execute}" target="NewWin" actionListener="#{helpBean.handleEvent}" ></hl:helplink>I tried to hard code the path of the jsf file into the popup but that gave an error that 'Page Cannot be Displayed'.
I tried to get the path of the JSF using the contectPath as follows:
var path= <%= renderResponse.encodeURL(renderRequest.getContextPath() + "/pages/epsHelp.jsp" %>;
window.open('"+path+"','helpPopup','height=200,width=400,status=no,toolbar=no,menubar=no,location=no,scrollbars=yes');",null);When i viewed the source of the parent page the javascript was showing the correct context path ie "/help/pages/myjsf.jsp". What might be the issue.Can you please help..
Thanks

Problems in tag h:commandLink

i use this tag in the test.jsp like this:
<h:commandLink action="details">
<h:outputText value="Details" />
</h:commandLink>
faces-config.xml like this:
<navigation-rule>
<from-view-id>test.jsp</from-view-id>
<navigation-case>
<from-outcome>details</from-outcome>
<to-view-id>details.jsp</to-view-id>
<redirect />
</navigation-case>
But when i click "Details",the routing doesn't work.
if i change the tag <h:commandLink> into <h:commandButton> like this:
<h:commandButton value="Details" action="details" />
then it works.
What's the problem with the tag <h:commandLink>?

JSF and commandlink, strange comportment (for a newbie)

Hello everybody, and excuse me for my bad english...
I am actually working (or learning) JSF. But i'm actually in front of a very strange thing:
When I have got two commandlinks on a jsp page pointing to the same method bean, the second sems not to be active!
Maybe my english is not clear, so the following code should be more clear:
My home.jsp:
<html>
     <head>
          <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
          <title>home</title>
     </head>
     <body>
          <f:view>
               <f:subview id="header">
                    <jsp:include page="links.jsp"/>
               </f:subview>
               <f:subview id="login">
                    <h:outputText
                         value="A really simple test for login/logout
                                 and display products     for logged in poeple"
                         id="presentation"/>
                    <h:form id="loginForm" rendered="#{userBean.loggedIn=='false'}">
                         <h:outputText value="Username"/><br>
                         <h:inputText value="#{userBean.name}" id="username" required="true"/><br>
                         <h:outputText value="Password"/><br>
                         <h:inputSecret value="#{userBean.password}" id="userpassword" required="true"/><br>
                         <h:commandButton value="Login" action="#{userBean.loginAction}" />
                         <br>
                    </h:form>
               </f:subview>
               <f:subview id="footer">

                         <h:commandLink id="hometousers" action="#{userBean.getAllUserAction}" value="go" />
                       </h:form>
               </f:subview>
          </f:view>
     </body>
</html>my links.jsp:
<f:subview id="header">

                         <h:outputLink id="headertohome" value="home.jsf">
                              <f:verbatim> home </f:verbatim>
                         </h:outputLink>
                         <h:commandLink id="headertoproducts"
                                           action="#{productListBean.productsAction}"
                                           rendered="#{userBean.loggedIn=='true'}">
                              <h:outputText value=" products "/>
                         </h:commandLink>
                         <h:commandLink id="headertousers"
                                           action="#{userBean.getAllUserAction}"
                                           rendered="#{userBean.loggedIn=='true'}">
                              <h:outputText value=" users "/>
                         </h:commandLink>
                    </td>
               </tr>
          </table>
     </h:form>
</f:subview>As you can see, home.jsp include links.jsp, and "idtousers" has the same action than "headertousers".
When I logg in with the "loginForm", the links included are visible and works fine.
But, always when I am logged in, the link at the bottom of home.jsp ("testlink") is unusable, it does absolutely nothing (just the # character appears in the url...).
And when i'm not logged in, the include links does not appear (normal), and the link at the bottom functions well.
I have tested several things like use several views, subviews, forms... but without results...
I hope I am clear.
Have you got any idea?
Thanks by advance.

Ok, this is the more simple example possible for this problem.
I have only two jsp(jsf) files, the first file (just below) caontains two commandlinks used to go on the second (by using the navigation rules with a managed bean).
The first commandlink works well, but the second doesn't do anything... (I just see the '#' character at the end of the url but nothing happens).
I use the 1.1 jsf implementation.
The first jsp file:
          <f:view>
               <h:form>
                    <h:commandLink action="#{simpleBean.createMsgAction}" value="destination" />
               </h:form>
               <h:form>
                    <h:commandLink action="#{simpleBean.createMsgAction}" value="destination" />
               </h:form>
          </f:view>The second jsp file:
          <f:view>
               <h:dataTable value="#{simpleBean.msgs}" var="row">
                    <h:column>
                         <f:facet name="header" >
                              <h:outputText value="string" />
                         </f:facet>
                         <h:outputText value="#{row.msg}"/>
                    </h:column>
               </h:dataTable>
          </f:view>I was thinking it's maybe a bug of this JSF version, but i haven't had the time to test with the 1.2 .
Thank you by advance for your help. (I always hope I am clear)

Problems in JSF t:dataTable /t:dataTable

hi
i am using <t:dataTable> to create jsf table.In the datatable each column has one <h:commandLink>.i had action methods to each and every column.At the same Jsf page,i am having some textfields using <h:inputText>.
My problem is when i click the datatable colume link,it goes to the same jsf page,but there is no textfields at the same page.i am not expected to same jsf page.i wants to navigate to some other jsf pages.i had one solution i.e,i used binding method for each and every Link.The problem was solved temporarly.eventhough i am having solution using binding method.it is not applicable for huge data as i have large data.so what should i do to have exact solution .At the same time,i don't need binding methods.
Advance thanks

Hi.
J solve the problem partly and here is the problem and solution:
Problem - JDeveloper 10.1.3 have problem in showing table when code look like this:
<h:dataTable width="350" value="#{infoBean.popular}" var="popular_">
<h:column>
<f:facet name="header">
<h:panelGroup>
<h:commandLink action="POPULAR">
<h:outputText value="Najpopularnije"/>
</h:commandLink>
</h:panelGroup>
</f:facet>
<h:commandLink>
<h:outputText value="#{popular_}" converter="ProductTitle"/>
</h:commandLink>
</h:column>
</h:dataTable>
Solution - When J change code to this 'Design' tab shows the table but not the text in 'outputText'(here #{popular_}):
<h:outputText value="#{popular_}">
<f:converter converterId="ProductTitle"/>
</h:outputText>
Please try this!

Problem passing parameters to commandLink in a column

Hi.
I'm using JDeveloper 11.1.1.7.0
I'm having this problem and I can't understand what I'm doing wrong.
I have a table like this:
<af:table value="#{bindings.myView.collectionModel}"
            var="row"
            rows="#{bindings.myView.rangeSize}"
            emptyText="#{bindings.myView.viewable ? 'No data to display.' : 'Access Denied.'}"
            fetchSize="#{bindings.myView.rangeSize}"
            rowBandingInterval="0"
            binding="#{backingBeanScope.myBean.t1}"
            id="t1"
            rowSelection="single"
            contentDelivery="immediate">
    <af:column sortProperty="#{bindings.myView.hints.PrId.name}"
               sortable="false"
               headerText="Nro. Proc."
               id="c2" width="50">
      <af:outputText value="#{row.PrId}" id="ot5"/>
    </af:column>
    <af:column id="c8" headerText="Check" align="center" width="70">
      <af:commandLink text="rowCheck" id="cl1" partialSubmit="true">
        <f:attribute name="rowKey" value="#{row.rowKey}"/>
        <af:serverListener type="serverAction" method="#{backingBeanScope.myBean.linkEvaluacionServerAction}"/>
        <af:clientListener type="action" method="clientAction"/>
      </af:commandLink>
    </af:column>
</af:table>
After lot of tests, serverListener + clientListener is the only way to run some code after clicking the link. I don't know why, but actionListener in the link only works the first time. The second time and so on, actionListener did not fire.
My problem is how to pass rowKey parameter to linkEvaluacionServerAction method:
public void linkEvaluacionServerAction(ClientEvent ce){
    Object key1 = ce.getComponent().getAttributes().get("rowKey");
     // actions with key1
I don't know why, but rowKey link attribute only takes its related value the first time I clicked on a link.
From the second and so on, key1 values null
How can I solve this? Any help is very appreciated.
Regards

Well, I rethink (again) the approach and solve it in this way:
<af:column id="c9" headerText="Evaluación">
                  <af:commandLink text="Evaluar Procedimiento" id="cl3"
                                  partialSubmit="true"
                                  actionListener="#{bindings.setCurrentRowWithKey.execute}"
                                  action="#{backingBeanScope.myBean.linkEvaluacionAction}"/>
                </af:column>
Parameter for setCurrentRowWithKey is #{row.rowKeyStr}
In my method linkEvaluacionAction I do some additional checks.
Hope this helps. Regards

Problem in JSF with Swing in a web application

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.

Problem with JSF 1.2 and Tomcat 6

Hello guys,
I have here:
Tomcat 6.0.10
JSF 1.2_04_b10_p01
I followed these steps without success:
http://forum.java.sun.com/thread.jspa?threadID=787962
http://forum.java.sun.com/thread.jspa?threadID=5156242
Here what I did:
1) Removed the following line in $TOMCAT_HOME/conf/server.xml
<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />2) Add the following lines to $TOMCAT_HOME/conf/web.xml
     <context-param>
     <param-name>com.sun.faces.expressionFactory</param-name>
     <param-value>org.apache.el.ExpressionFactoryImpl</param-value>
     </context-param>3) Add the following libs to $TOMCAT_HOME/lib
jsf-api.jar
jsf-impl.jar
jstl-1.2.jar
4) Add the following lines to $MYAPP/WEB-INF/web.xml
     <listener>
          <listener-class>
               com.sun.faces.config.ConfigureListener

               com.sun.faces.application.WebappLifecycleListener
          </listener-class>

Thank you.

Thank you for the answer rlubke,
Well this happened because I had compiled the project with the jstl-1.1
The workaround to make jsf 1.2 run on tomcat 6 really works.
But now I have a problem because the JNDI tree in tomcat is read-only ( ro )
and I need to bind a object in the JNDI so an exception happens:
WARNING: Ocorreu um erro inexperado:
javax.naming.NamingException: Context is read only
         at org.apache.naming.NamingContext.checkWritable(NamingContext.java:903)
         at org.apache.naming.NamingContext.bind(NamingContext.java:831)
         at org.apache.naming.NamingContext.bind(NamingContext.java:171)
         at org.apache.naming.NamingContext.bind(NamingContext.java:187)
         at org.apache.naming.SelectorContext.bind(SelectorContext.java:171)
         at javax.naming.InitialContext.bind(InitialContext.java:400)Here is the code:
try{
     Context newContext = new InitialContext();
     newContext.bind( dataSourceWrappedID, wrappedDs );
     newContext.close();
}catch(NameAlreadyBoundException nabe){
     // ok no problem..
}catch(NamingException ne){
     if ( log.isWarnEnabled() ){
          log.warn("Ocorreu um erro inexperado:", ne);
}You know how to make the JNDI tree in tomcat read-write ?
Thank you a ton. :-)

Problem in JSF action mapping for ZOHOwrter

Hello Every one,
I am struggling with a problem by using zohowriter in JSF Frame work, my problem is..
I have developed an application to open and edit a Document which resides in server and save it in server in another path, for this purpose we are using ZohoWriter. For this application the Struts frame work is working fine.
I have designed xhtml page by using struts framework as bellow,
<body>
<form method="POST" action="http://export.writer.zoho.com/remotedoc.im?apikey=ad40de81a92f4d644b474276c7ac1640&output=editor" target="_self">
<input type="hidden" name="url" value="http://customers.info-sun.com/itrack/templateDocuments/TestPlan.doc">
<input type="hidden" name="saveurl" value="http://localhost:8080/Struts/zoho.do">
<input type="hidden" name="filename" value="mydocument.doc">
<input type="hidden" name="id" value="12345678">
<input type="hidden" name="format" value="doc">
<input type="hidden" name="persistence" value="true">
<input type="submit" value="Edit" class="divbutton" name="submit">
</form>
By using above code that editor is calling the "saveurl" attribute value while saving the document, that is automatically executing the Action class and saving the Document in specified server path.
But,
In my application we are following JSF framework,
In my application I have written the xhtml page like,
<form id="myform" method="post" enctype="multipart/form-data" action="http://export.writer.zoho.com/remotedoc.im?apikey=ad40de81a92f4d644b474276c7ac1640&output=editor">
     <h:commandButton value="Edit" />
     <h:inputHidden id="url" value="http://customers.info-sun.com/itrack/templateDocuments/TestPlan.doc" />
     <h:inputHidden id="filename" value="TestPlan.doc" />
     <h:inputHidden id="id" value="12345678" />
     <h:inputHidden id="saveurl" value="http://customers.info-sun.com/itrack/zoho.fileDownload" />
     <h:inputHidden id="format" value="doc" />
</form>
in the page designing if I use <h:form> this tag is not containing action attribute , so I am giving by command button but it is not working.
So, I continued with html form.
also, if I specify the "saveurl" attribute mapped with backing been , it is executing in page load only , So My actual intention means after editing it needs to call but it is not happening, while loading this method is calling so other problems are raising.
Can any one please guide me that, what is my mistake and how to over come.
Thanks and Regards

Hi,
I got solution for the above problem.
I am calling a servlet instead of calling jsf flow, I got that, the zohowriter calling only lifecycle method for saveurl attribute.
Thanks and Regards

DATE field problem in JSF code

Hi,
I am a newbie on JSF and working with a JSF application development. I have a problem with a data type: DATE. Here is what had happened; I tried to write a new record to a table, in my "write" paragraphs I have the following codes:
tabelOneDataProvider.setValue("joindate", rowKey, joinDate1.getSelectedDate());
tableOneDataProvider.commitChanges();
The problem is when I was running the program to write a record, I got the following error:
Cannot append new tableOne data: java.lang.RuntimeException: Number of conflicts while synchronizing: 1 SyncResolver.INSERT_ROW_CONFLICT row 1 Can't infer the SQL type to use for an instance of java.util.Date. Use setObject() with an explicit Types value to specify the type to use.
At that point, I was trying to write a DATE value from a "calendar' component (joinDate1 field with MM/dd/yyyy format) into a field name: "joindate' (data type is DATE) in tableOne file.
Any advice on resolving this problem? Please help me to get more knowledge on this. Thanks!

Hi,
You must use sql type. So instead of:
tabelOneDataProvider.setValue("joindate", rowKey, joinDate1.getSelectedDate());
tableOneDataProvider.commitChanges();try something like:
java.util.Date date = joinDate1.getSelectedDate();
java.sql.Date dateToInsert = new java.sql.Date(date.getTime());
tabelOneDataProvider.setValue("joindate", rowKey, dateToInsert);
tableOneDataProvider.commitChanges();best regards

Getting a problem in JSF - Spring Integration

Hi,
We have a web application in which we are working on JSF using MyEclipse. I am now trying to integrate spring framework into the project for having IOC for middle layer.
well I am getting problem in setting class attribute through Spring.
How I did is I added a class First.java initialized by application.xml The code is
<beans>
     <bean id="first" class="com.model.service.impl.first"
          abstract="false" singleton="false" >
     <property name="name">
          <value type="java.lang.String">to enter</value>
     </property></bean>
</beans>In web.xml I did the following change for Spring
     <servlet>
             <servlet-name>SpringContextServlet</servlet-name>
             <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
            <load-on-startup>1</load-on-startup>
     </servlet>I added this first class in backing bean as a property. My faces-config.xml code is
          <managed-bean>
          <managed-bean-name>EducInfo</managed-bean-name>
          <managed-bean-class>
               com.view.beans.StudentEducInfo
          </managed-bean-class>
                <managed-property>
               <property-name>ft</property-name>
               <value>#{first}</value>
          </managed-property>and I called it from jsp(JSF) page as
<h:outputText value="#{EducInfo.tstFirst}" />the function tstFirst in EducInfo (backing bean) is
     private first ft;
     public String getTstFirst() {
          tstFirst=ft.getName();
          return tstFirst;
I am getting error 'Expression Error: Named Object: 'first' not found.'
Any idea? Any workaround would also be appreciated.
Thanks,
Arsalan

Your server is not able to find anything matching the requested file.
Well, just explore your archive file (possibly your .war file) and look at the path of the index file.
Please post your url. If pro11 is your project name (the root) then ensure that the index file is by itself ie the path should be shown as blank in your war file.
Or mention the exact path of your index file in the url.

File Upload Problem in JSF

Hi all,
I have a problem in file upload. I have a file upload third party component which uploads the file with the filter action depending on the url. My requirement is to trace the uploaded filename for addressing it with the database record. So I need the filename in my backing bean to store it in the database. Ho can i get the filename from view page to backing bean. Any Ideas and help please.
Many thanx,
vijaycanaan

Mr BalusC,
Yes Iam talking about a custom made upload component. The fileupload tutorials u send are good but my requirement is not meeting them. Among my requirements one is mutilple file uploads in the single view page. This is possible at present with my custom upload componet. Only if the problem gets solved. Any way once again please think on my problem and give your solution on it.
Here is my problem:
The problem is I have to access the components from view page which this kind of requirement possible in jsp by request parsing which results the key value pairs of the form components. This same thing/way I should get in backing bean from JSF view page.
The solution I want may like as follows.
Note this code is incorrect and wrong but for to understand my requirement.
someobject.getComponentIdValue("clientID"); which returns a string value as d:\images\Tutle.jpg
The clientID is upload file component' Id . In the request it may be the key associated with value as file complete path. By this kind of way my upload filter is able to get the orignal file. Ok i need this in my backing bean to get the orignal filename to insert into the database. Please for this give the solution or reply.many thanx,
vijaycanaan.
