Are you using the viewer or the APIs to run your reports?

Hi,
I'm using the API's.
I followed this blog : http://www.birt-exchange.org/org/forum/index.php/blog/45/entry-442-using-jsf-2-0-with-birt/&#comment2057

Ah. Let me follow Kris's blog and see if I run into the same issues. I have JBOSS 5.1. I'll try it first. If it works for me, I'll download 7 to see if I have problems there. I'll let you know.

I had the same problem using JBoss 7.1. The charting framework is using Xerces. JBoss 7 already brings Xerces in a different version. Can you try to remove the xerces jar from the web-inf lib of your application before deploying to JBoss as a war file.

mwilliams

I'm having the same problem using Tomcat 6, as well, so I'm not sure. I'll keep digging.

Forgot to mention that it worked fine when I ran it on Tomcat from Eclipse, but failed when I exported the war file to Tomcat.

If I remove the xerces jar I obtain a nullpointerexception when invoking ther report from the xhtml page

In his example, I got it to show by changing the PDFRenderOption code to: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
// set render options including output type
HTMLRenderOption options = new HTMLRenderOption();
ByteArrayOutputStream outs = new ByteArrayOutputStream();
options.setOutputStream(outs);
options.setImageHandler(new HTMLServerImageHandler());
options.setBaseImageURL("images");
options.setImageDirectory("E:/apache-tomcat-6.0.36/webapps/JSF_2/images");
options.setEmbeddable(true);
options.setOutputFormat("html");
task.setRenderOption(options);
</pre>
 
Let me know if this solves it for you.

could you tell me more about these two parameters because I'm using JBOSS 7.1. what do you have in this folder?

mwilliams

That's where your charts will go (report engine will put them there), so that the app can find them for the display. The "images" one is the relative location of the folder holding the chart, to the app. If you look at the page source, this should be the src for the img. images/tempImageName.png

It doesn't work anymore. I created the where the charts will go in my jboss/appclient. I tried a lot of things but nothing works. With eclipse's local web browser and firefox the chart simply isn't showing up and with chrome I got a HTTP 404 caused by infound ../custom***.svg

I think the problmem comes from my 'options.setBaseImageURL' and 'options.setImageDirectory'

mwilliams

Let me download JBoss7.1 and try it on there. I'll let you know what I see.

mwilliams

It works for me, in JBoss 7.1.1 in Chrome and Firefox. Here are my settings: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
options.setBaseImageURL("images");
options.setImageDirectory("E:/JBoss/jboss-as-7.1.1.Final/standalone/deployments/JSF_JBoss.war/images");
</pre>
