How to refresh an Image component

Hi,
jdev 1.1.1.5
I have a parent page with a table to show employees and a tab to show detail of employees
Detail is in a Region and is sharing the same datacontrol with parent page and i don´t have any parameter in task flow.
Sincronization Parent - Detail works fine using Partialtriggers.
Detail Region has a button for upload an image and another button to process the image and an Image component(by servlet) to show it.
Process button call an operation exposed in AM, This method do Insert or Update in IMAGE TABLE.
The problem is than image is not refreshed until i do full refresh the page.(but only occurs when updating the image, for insert the Image component show the new image)
I tried this code at end of process button logic but i can't achieve refresh the image.
public void saveFileUploaded() {
      oper =
          bindings.getOperationBinding("myMethodInAM");
       Map args = operaImatge.getParamsMap();
       args.put("empId", empId);
       args.put("imatgeBlob", createBlobDomain(file));
      oper.execute();
// try refresh entire region method 1
       AdfFacesContext.getCurrentInstance().addPartialTarget(JSFUtils.findComponentInRoot("r1"));
   // try refresh image component
       AdfFacesContext.getCurrentInstance().addPartialTarget(JSFUtils.findComponentInRoot("imageEmp"));
// try refresh region method 2
       RichRegion region = (RichRegion)JSFUtils.findComponentInRoot("r1");
       region.refresh(JSFUtils.getFacesContext());
}Any suggestion?
Thanks in advance

Hi,
I have updated the use case at first message.
you wrote
you have a binding to the component that is holding the image.. and then refresh the container region..
that would refresh the image inside.
can you give two cents?
i just created a binding for image component but
what must i do?
Remember
the button for process image (operation exposed in my AM service) and Image component(by servlet) are in the same .jsff.
Means the changes occurs in same jsff without interaction with parent page.
Thanks,

How to refresh an image's source value

I have an image component in a page fragment. When the page opens the image's source is set to the URI for a gif
What I want is to be able to update the URI to another image once a managed bean's property value changes.
The image component is bound to a managed bean property, pageAnimationImage.
I'm new to ADF and tried to set the partial trigger when the property value is set and also set the image's clientComponent to true
AdfFacesContext.getCurrentInstance().addPartialTarget(pageAnimationImage);
I searched this forum and other blogs but couldn't find anything related.
I'd really appreciate it if someone has a suggestion or point me to a related case.

You can try to bind the component to broader scope e.g. pageFlowScope or applicationScope and see if this works.
One other thing to try is to search for the component via its id
// find a jsf component
private UIComponent getUIComponent(String name) {
FacesContext facesCtx = FacesContext.getCurrentInstance();
return facesCtx.getViewRoot().findComponent(name) ;
}The method should find the component by its id. If you find it this way use the returned component to set the ppr on it with
// PPR refresh a jsf component
UIComponent image = getUIComponent("MyImageID");
if (image != null)
AdfFacesContext.getCurrentInstance().addPartialTarget(UIComponent);Timo

How can i set a image dinamically in a image component (ADF Mobile)?

Hello everybody,
I have to consume a rest service and get a url. This url is redirected to one image. After reading this image, how can i set he in a adf mobile image component?

Hi,
bind the mobile image component URL to a managed bean and have the managed bean. Then use the bean setter to set a new URL string and ensure (when creating the Java class for the managed bean) you have JDeveloper creating the property change event handlers.

Setting source property of Trinidad image component using java script

Hi,
Can anyone tell me how to set the source property of Trinidad Image component using javascript.
i tried document.getElementById("f1:img").source="/images/neha.gif".
But its not working
Thanks
Neha

Hi,
Bases on the solution you suggested, i tried the img component to change the image on OnMouseOver and OnMouseOut. Its working fine in a normal browser but doesnt work in Mobile browser. May be because mobile browser supports only trinidad components. I then tried the option of backing bean
" Or you can expose the component to a backing bean by setting its "binding" attribute. JDeveloper can create a backing bean from the wizard if you don't already have one. This will get you a CoreImage object in the bean, and you can change the source with its setSource method."
. So i bound the omMouseOver event of the trinidad image component to a backing bean. Inside that i am changing the source and refreshing the component.
<tr:commandLink id="cl1" action="goAlerts" styleClass="listingLink2">
<tr:image source="/images/alert.gif" id="i4"
binding="#{Images.alertOnMouseOver}"
onmouseover="#{Images.alertOnMouseOver}"/>
</tr:commandLink>
Images.java
public void setAlertOnMouseOver(CoreImage alertOnMouseOver) {
this.alertOnMouseOver = alertOnMouseOver;
alertOnMouseOver.setSource("/images/alertSelect.gif");
RequestContext context = RequestContext.getCurrentInstance();
context.addPartialTarget(alertOnMouseOver);
System.out.print("Test");
So what i found is setAlertOnMouseOver is getting called but not MouseOver event but when the page is loaded. Can you please tell me where i am going wrong?

How to refresh the client area

i used javax.swing.JPanel and drawed many shapes with paintComponent method. i wonder how to refresh the client area.
ps: i first used paint method to draw shapes, but i found a copy of the menu bar appeared. at last i found paintComponent method works, but when i tried to refresh the client area with repaint, the same scene appears.
could some one help me?
thanks in advance!

when i tried to refresh the client area with repaint, the same scene appears. When you invoke repaint() on a component, the paintComponent() method of that component is invoked. So unless your code in that method is different, the image painted will be the same.

How to embed an image in swf at run time?

Hi all,
I have created an Image component in flash which is having a "imageSource" paramter, where in a user can provide the path of his/her image(both from web or from harddisk). I want that image to be compiled with the swf. how can i do that?......any help will be greatly appreciated
Thanks,
Roopesh

Hi kglad,
Thanks alot for your quick reply.
well I have created such a custome component, which user can drag on stage and configure accordingly. If a user provides the path of a image which is on server, things works fine as when i deploy my swf to server it fetches the image properly but if a user provides the path of a image which is present locally on hardisk, image is not loaded when the swf is deployed to server as the path provided is local . So i am searching for a solution for resolving this path conflict issue in desgin and deployment phase. one probable solution is, if the images gets embedded with swf but embedding is not possible at run time. Do you have any other solution for this?

How do I store images in a jar file to be displayed on a jsp?

Afternoon all,
I have created a java component which accepts some parameters and returns a string. The returned string contains html tags to display a table in a webpage when rendered through a browser.
I want to be able to add this component to any java web project to display my table. The problem is that I want to use images in my table to give the appearance of curved corners.
How do I store images in my component and render to a webpage?
Thanks in advance,
Alex

You won't be able to make the install of this library as simple as the installation of a jar file. You can't access the images directly in the jar.
There are a few approaches you can take:
1 - jar file + resources:
Have the install as being a jar and a "resources" directory which you store all the images in. Thus the images become part of the web application/web site and are accessible. Probably need to allow an entry in web.xml to configure where/what this directory is called.
2 - jar file only:
Provide a servlet to access the images, which will load them from the jar file, using the ClassLoader.getResourceAsStream(). Requires declaration of a servlet in the web.xml file. Won't be as efficient as having the images on disk, but will keep them bundled in the jar file.
you would generate code such as <img src="myImgServlet?img=.....">

How to set a Swing component as Modal on a SWT Component?

How to set a Swing component as Modal on a SWT Componen?.I mean, I have a SWt Component window and from that window I am displaying a SWING Component Modal window.
The problem is my swing window is not working as Modal always.
When I opened the swing window from SWT window,swing window is working as Modal.But if Idouble click on Menubar or Title bar of the SWT Window then my Swing window goes back.If I click on any other part of the SWT window.. then once again Swing window is working as modal.
Can any one suggest me to solve this?
I think this is isuue related with Swing over SWT..

Hi Kasturi,

It worked on this and on one other thread, but this is still open: How to upload the image
> want upload the images from the client side machine

In the thread I just referred to, I already provided information about the HTMLB upload control. With this at hand, you'll get the file from the client to the server.
At server side, get an ICollection instance where you want to store the file and create the corresponding resource. See https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/javadocs/nw04/sp12/knowledge management/com/sapportals/wcm/repository/icollection.html#createresource(java.lang.String,%20com.sapportals.wcm.repository.IPropertyMap,%20com.sapportals.wcm.util.content.IContent)
