Hello,

I have following problem. I create an image of a byte array with this code
snippet:

Image image = Graphics.getImage(imageName, new
ByteArrayInputStream(imageData));

It works fine when I start my application from eclipse. If I build a war
and deploy it on jboss, I don't will see my image.

How can I do that it works on jboss as war and from eclipse?

did you check the FAQ? E.g.

Hi,

I read the FAQ article but I think it don't help me. The imageName in the
code snippet of my first post has the following path

"/icons/test"+Math.random()+".gif"

I don't see the generate image of the image byte array on this path. Which
resource files or entries of images should in the build.properties file?

The first parameter is used to uniquely identify the image (the one
given by the stream). In addition the path partly specifies where to
store a copy of the image so that is is accessible by the browser
(but that may change in the future).

Did you make sure that the imageData isn't empty?

My previous suggestion might be misleading (see above)

Hello,

Yes, I'm sure that the imageData isn't empty.
What can I try else?

Puh, not sure. How do you display the image?

Hello Rüdiger,

I diplay my image in a browser. Here is the code snippet how I get the
image of the imageData and set the image in the browser control.

imageName = "/icons/test"+Math.random()+".gif";
Image image = Graphics.getImage(imageName, new
ByteArrayInputStream(imageData));
browser.setText("<img src=\""+imageName+"/>");

Hi Kristin,

the path started with "/" like in your imageName means root of the
server and not the relative path. When you deploy your application as
war in Tomcat this path does not exist (there is one more folder witch
is the war filename) - in Eclipse Jetti the application is in the app
server root. Try to change the path to
"icons/test"+Math.random()+".gif"" (without leading backspash).

Best,
Ivan

Hello,

I changed the path of my imageName but it doesn't help. Do you have any
other ideas to solve my problem?

Hello,

I tried to set my image on the browser as backgroundImage and then it
works fine. Which control can I use to set an image? Or, how can I set a
backgroundImage once, so that the backgroundImage wouldn't repeat?

Not sure whether I understand this question correctly. You can set an
image on any control that supports setBackgroundImage().

Preventing a backgroundImage from repeating is not possible. See the
Javadoc of setBackgroundImage:
"The background image is tiled to fill the available space."

I think the advise that Ivan gave you is absolutely right. Even though
an absolute path like /icons/... is appropriate for Graphics
#getImage(), you can not use it directly in your html code - it will
work from Eclipse but not in a deployment. Try this instead:

imageName = "icons/test" + Math.random() + ".gif";
Image image = Graphics.getImage( "/" + imageName, ...

browser.setText( "<img src=\"" + imageName + "/>" );

Hi,

I don't set a background image. I want set a image but I don't know what
control is the best.
I try to set an image on a browser with the following code but if I deploy
the application as war, I don't will show the image.

imageName = "icons/test"+Math.random()+".gif";
image = Graphics.getImage(imageName, new ByteArrayInputStream(imageData));
browser.setText("<img src=\""+imageName+"\"/>");

I try to set an background image as test whether the image is correct on
the browser with the following code and it works.

imageName = "/icons/test"+Math.random()+".gif";
image = Graphics.getImage(imageName, new ByteArrayInputStream(imageData));
browser.setBackgroundImage(image);

For this reason, I search a control where I can set an image. I tried this
with a label but I can scroll this control. It is right?

I have no idea what I can do to solve my problem.

Hello,

I have a solution. :D
It is correct that I set my image path without a "/" at the beginning.
But if I deploy my war and call my RAP application, the path of the
process image will be
"<servername>/<servletName>/org.eclipse.swt.browser/icons/test0.21146213068309738.jpg ".
I think that the package name of the browser is false in these url. I see
my image when I delete the package name of the browser.
I don't know why but I changed my code snippet from:

imageName = "icons/test"+Math.random()+".jpg";
image = Graphics.getImage(imageName, new ByteArrayInputStream(imageData));
browser.setText("<img src=\"" + imageName + "\"/>");

to this code snippet:

imageName = "icons/test"+Math.random()+".jpg";
image = Graphics.getImage(imageName, new ByteArrayInputStream(imageData));
browser.setText("<img src=\"" + "/<servletName>/"+imageName + "\"/>");

I set for the "<servletName>" the application servletName and then it
works.
