Visual JSF pages
am having a problem with a web app i am making using visual JSF pages.
I am interacting with a MYSQL database. I have a problem with displaying the blob types from the database in the actual visual table and on screen,.
I have tried converting it to image them using image component to display it but it dosent work. Also when i set that field to image for table layout i get an error invaild type.
Please someone help me out.
I tried to create servlet as how the blog site said it should be done but the page is freezing up now. Its not Loading but its also not crashing its like its stuck in a loop.
this is what i wrote in jsp part to get servlet running.
<h:graphicImage value="image?id=#{ItemPage.txtItemNum}" />
Please tell me how to resolve this issue if you need screen shots of servlets i can supply them. Please help me though I have been trying to rectify this problem for a couple of weeks now.
Thx.

Importing visual jsf page into another jsp page
Hi
I am developing a web application using jsp and struts. I want to embed a visual jsf page that Ive created into another jsp page (which is a normal jsp page, not a jsf one.)
Ive tried quite a few things but nothing seems to work..
<jsp:include page="Page2.jsp">
Ive surrounded the code in the f:subview tags. still doesnt work.
Ive tried using <jsp:useBean id="Page2" scope="page" class="visualwebapplication.Page2" > .. It does not give me an error, but does not embed the page as well. Do I need to some other code after this to use the above bean to display the page.
Any help would be greatly appreciated.
Regards
Sparsh AgarwalHi

Accessing entity class field values in a visual JSF page
There is a convenient way to access a session values into a JSF visual page using the following:
String mySessionValue = (String) getValue("#{sessionScope.name}");Like the same, are there any ways to access entity class field values into a visual JSF page? Are there any concepts similar to "entityClassDataProvider" that can be linked to a table component in a visual JSF page?
Thank you.My question is about (Netbeans visual pack) Java Persistence API and how to display the information from an entity class to a JSF page. But the above mentioned tutorial is about the ordinary visual table presentation.
Thank you. -
Method call before visual web jsf page loads
Hi All.....
I have written a method in a java class that accesses the mysql backend db to check if a process is still running. If the process is still running, a JOptionPane is produced informing the user of this and offers an <ok> option(to check the process status again) and a <cancel> option(to redirect the user to the homepage). If the process is completed, I want the page to just load as normal. I want this method to be called before the visual web jsf page loads. I have the method call in the super_init() method of the page and everything seemed to be working fine, the problem I have run into is that if I set the value in the db to show the process is running, the JOptionPane is produced(like it should be), and then if I set the value to show the process has completed and choose <ok> from the pane, the page loads.....this is what I want. Now, after the page loads, if I set the value in the db to show the process is running again, the JOptionPane is produced again right after I apply the changes to the db edit!!!!. I don't know why this is happening. Should I be calling the method from somewhere other the super_init()????? I have tried the method call in the prerender(), preprocess(), and destroy() methods all with the same results.
Anyone have any ideas on what the problem could be??
Thanks in advance.
SilgdThe Java part of a JSP/Servlet based webapplication runs physically at the server machine.
Only the HTML/CSS/JS part which is generated by the webapplication and sent to the client physically runs at the client machine.
JOptionPane is a Java Swing component which thus runs at the server machine. So you as client would only see it when both the server and the client runs at physically the same machine. Which is often only the case in development environment and doesn´t occur in real life! There is normally means of two physically different machines connected through the network/internet.
To solve your actual problem, look for Ajax poll techniques. To display an alert or confirm dialogue in the client side, you use Javascript for this. -
JSF Page Template error in Visual Editor
Hi!
I've developed a jsp page template with an attribute called BackingBean. This attribute is a mypackage.view.BackingBeanTemplate class and it works perfectly when I open the template in visual editor.
When I create a new JSF page using my jsf page template and fill attribute BackingBean with a class that extends mypackage.view.BackingBeanTemplate, the visual editor send me the following error in Messages - Log:
WARNING: A problem was encountered executing the page. Using fallback rendering.
javax.el.PropertyNotFoundException: The class 'oracle.adf.view.rich.component.fragment.UIXPageTemplate$AttrMap' does not have the property 'BackingBean'.
When I run my jsf it works perfectly. Just in visual editor it doesn't render my page.
Can I use only primitive types and wrappers (String, Boolean, Integer, etc) in jsf template pages?
Anybody could help me?
Thanks
GleberHi,
actually i used a template that references a type DCIteratorBinding using EL and this works fine. So there is no limitation in the type you pass as an argument. My assumption is that the IDE doesn't instantiate super classes, which is why the property is not found. Does the subclass call super() in its constructor? Anyway, feel free to file a bug

Setting the value of a hidden field in a Visual Web jsf page
Hey All,
I am new to jsf and need some help with the following. I have written a method in the java portion of the jsf page that will get the selection(s) from a listbox and return them as a string. I need to assign the value of that string to a hidden field in the jsp portion of the page, so that I can pass the string as a parameter to a servlet. I have tried the following code in the "button_action", in the java portion of the jsf page, to assign the value of the string, returned from method, to the hidden field:
hiddenField.setValue(string);
This is not working. Any and all help on this matter is greatly appreciated.
Thanks in advance.Here is the tag for the hidden field when the "hidden field" component is added from the pallette, I addded the "value" and "id". The name of the class is ReportStandard, which extends the AbstractPageBean.
<webuijsf:hiddenField binding="#{ReportStandard.utilSelHF}" id="utilSelHF" value="#{ReportStandard.utilParams}"/>This is how I am calling the hidden field in the servlet:
utils = request.getParameter("form1:utilSelHF_field");Here is the code for the button_action:
public String runReport_button_action() {
this.utilParams = get_utilSelection();
return "sRptrslts";

Maintain the status of a Visual Web JSF page
Hello,
I have a JSF page in which I display several images.And when the user click on one image it will be viewed on her real size. So the user will be redirected to another page. Then, if he go back to the previous page will be displayed containing the associated images. But when he click on an image, the event of the click is not handled and the second page is not displayed.
I think that it is due to the life cycle of the page.But I don't know How to do.
How can I please maintain the state of the page listing the images in order to have the events still handled.

JSF page not rendered in Design View (JDev 11.1.2.1.0)
Hi!
Recently strange behavior in JDeveloper 11.1.2.1.0) begins: JSF pages in some projects are not rendered anymore. We enabled "Show Design time Messages in log" in JDev Tools/Preferences/JSP and HTML Visual editor and message
WARNING: A problem was encountered executing the page. Using fallback rendering is shown in log. This is visible on this snapshot:
[http://dl.dropbox.com/u/14304804/design_view_problem.jpg|http://dl.dropbox.com/u/14304804/design_view_problem.jpg]
What is common to all of the projects with this issue is that we run "Remove ADF Security Configuration" which was enabled before and we implemented our custom security using phase-listener.
Any idea what is wrong here?
Regards,
Sašo
Edited by: Sašo C. on May 21, 2012 2:24 PMIt's a limitation, if you will, of the way JDeveloper works. It essentially runs your JSF page in order to get the rendering. At design time, the phase listener is obviously messing things up since you're not in a proper secured environment - hence the workaround to bypass your phase listener at design time.

How to use javascript in visual jsf
I have a web project and I am using visual jsf in netbeans. My problem is I cannot with javasciprt.
When I clicked to a button I want to make some check with javascipt and then run server side java code. With jsp I used to add onclick javascipt and if it is ok, I just submit to servlet and run the java code in servlet. How can I do this with visual jsfIf you are trying to display total number of pages in a report, Add the below formula in the column of the report and hide that column in the report.
FX = sum(count(1))/25
You can then reference the column in the narrative view like this: "Total pages in the report are @5" and out put may be "Total Pages in the report are 30".
Or
You can also use something like the below:
To calculate them use fi:
CEILING(CAST(RCOUNT("FactColumn In the Report (Sum All)") as DOUBLE)/ 25) for the page number
CEILING(CAST(COUNT("FactColumn In the Report (Sum All)") as DOUBLE)/ 25) for the total pages
Put the above formula in the column and reference it in the narrative view like I mentioned in the previous example.
If you are report view is pivot, then please refer to this link: http://oraclebizint.wordpress.com/2008/01/17/oracle-bi-101332-pagination-in-pivot-tables/
Hope this helps.
Thanks,

Set text in Visual JSF textfield from javascript
HI,
I want to pass a variable from a javascript to put into a visual jsf textfield that is connected to a Bean variable like this:
<webuijsf:textField id="myLat" style="left: 96px; top: 336px; position: absolute" text="#{CreateNewPage.latitude}"/>
I use this library: xmlns:webuijsf="http://www.sun.com/webui/webuijsf"
I found a guide for this using regular jsf-tags, but that doesn't work for the visual jsf tags. Link: http://balusc.blogspot.com/2009/05/javajspjsf-and-javascript.html
I managed though to change the field to some sort of text by using:
var lat = 'text';
document.getElementById("form1:myLat").textContent = lat;
in my javascript. But this just replaces the textfield to some stand alone text, and the variable in my Bean isn't changed at all. I tried using .value and .text instead of .textContent but it doesn't work. What am I doing wrong here? I'm new to JSF by the way. Thankful for any help.I've now read the article and understand everything better. Also funny that I got a reply from the author of it here :)
Sadly I have to use javascript I believe since I'm using a google maps api that uses it.
Anyway, I still can't get it to work properly.
now my jsp look like:
<webuijsf:form id="myForm">
<webuijsf:textField id="my2" style="left: 528px; top: 0px; position: absolute" text="#{EditPage.latFromMap}"/>
</webuijsf:form>
and in my JS:
document.getElementById("myForm:my2").text = 'text';
document.getElementById("myForm").submit();
I now get to the setLatFromMap() setter Method for my variable in my EditPage bean, but when I do a print out of it it's null. Also the textfield on my page becomes blank after the refreshing of the page. of Am I still missing some of the concepts? thx -

I am new to NB5.5. However, when I create a 'web application' project then I get the option to create 'JSF Pages from entity class' in the persistence category but not while creating a 'visual web application' project. Is there a way of getting this option in visual web applications?
Regards
RajeevHi, may I know what you mean by Visual Web Application?
Creating JSF Pages from Entity Classes is just a way to increase the speed of developing a web application (a database must already be existing, connected to netbeans for you to use this option). -
Error loading JSF page popup window - Cannot find FacesContext
Hello,
I am trying to load a popup window from my Visual Web JSF page. The popup window itself will be a Visual Web JSF page also.
As an example, i have 2 buttons on my original page with jsp tags as follows::
<webuijsf:button binding="#{Page1.button1}" id="button1" onClick="window.showModelessDialog('./PopupPage.jsp'); return false;"
style="left: 19px; top: 16px; position: absolute" text="Button"/>
<webuijsf:button actionExpression="#{Page1.button2_action}" binding="#{Page1.button2}" id="button2"
onClick="window.showModelessDialog('./PopupPage.jsp');" style="position: absolute; left: 20px; top: 44px" text="Button"/>
When i click Button1, the popup window appears but will not load the page within the window. I get the following report in the server log:
StandardWrapperValve[jsp]: PWC1406: Servlet.service() for servlet jsp threw exception
java.lang.RuntimeException: Cannot find FacesContext
at javax.faces.webapp.UIComponentClassicTagBase.getFacesContext(UIComponentClassicTagBase.java:1811)
at javax.faces.webapp.UIComponentClassicTagBase.setJspId(UIComponentClassicTagBase.java:1628)
at org.apache.jsp.PopupPage_jsp._jspx_meth_f_view_0(PopupPage_jsp.java from :102)
at org.apache.jsp.PopupPage_jsp._jspService(PopupPage_jsp.java from :77)
ETC ETC
If i click Button2 (which does NOT return false in the onclick Script and thus submits the first page) the first attempt fails with the same error, but if i try a second time the popup window displays and loads the page correctly.
Any solutions would be greatly appreciated as this is driving me crazy :-s
Edited by: coxy69 on Jan 9, 2008 10:29 PMCannot find FacesContextThis generally indicates that you invoked a request which points to a JSP page which contains JSF tags, but that the request itself isn't passed through the FacesServlet. Make sure that the request URL is covered by the url-pattern setting of the FacesServlet in the web.xml.

Hi guys,
I've a quick question...I'd like to use a visual web environment for building jsf 2.0 application...I used in the past visual web jsf from woodstock for netbeans, but for latest releases it's not supported.
Could you say me some solution free or for pay to visual build (drag and drop) jsf 2.0 application?
Any help is appreciated,
Thanks,
RegardsThe best I can come up with is to use a wysiwyg editor like Dreamweaver to do the basic (X)HTML and CSS markup and then take what it produces to transform it into JSF pages with your favorite text editor or IDE.
Eclipse + the Web Tools Platform gives some support for "visual editing" - no drag and drop, but you can see visually in the IDE itself the changes you make to the code.
http://www.eclipse.org/webtools/jsf/main.php
edit: upon further reading, it seems the JSF-tools of WTP actually do support some form of drag and drop editing. You learn something new every day. -
Retrieve data passed in session from another application in visual jsf
hi,
I'm using jboss 4.2.2, visual jsf, etbeans 6.0.1
My application needs to read the data passed in session from the calling application.
i try to get it using the below in init()
HttpServletRequest request=(HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
String value=(String) request.getAttribute("id");
System.out.print(value);
But it always prints null.
any idea??
Thanks.Hi,
My value is still null.
I created a simple web application. In the jsp page, ==>
<form method="post" action="http://localhost:8080/MyApp/">
<input type="hidden" name="username" value="ME"/>
<input type="submit" value="Submit" name="Submit"/>
</form>
In MyApp, which is a Web application with Visual JSF, in the welcome file init() method, i get the values ==>
String value = (String) FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get("username");
System.out.print("request value in welcome page init() = " + value);
Fearing loss of data by request, i tried in session too. But no luck.
