Problems with Scripts on deployment

Hello @ll, 
 
I am currently testing the creation of reports in BIRT 2.2.2 and their deployment on a Tomcat application Server with Standard BIRT 2.2.2 Runtime environment. 
Therefore I installed a 6.0.16 (using JDK jdk1.6.0_04 on Win XP) and deployed the Webapplikation WebViewerExample within it. That works pretty good, if i am using "normal" reports. 
 
My problem is a special requirement I got for the project: It has to be possible to sort the columns of the report table dynamically asc/desc via a click on the row headers. I found a good article about how to realize this on the web: 
<a class='bbc_url' href='http://digiassn.blogspot.com/2007/05/birt-strong-suit-is-in-realm-of-online.html'>http://digiassn.blogspot.com/2007/05/birt-strong-suit-is-in-realm-of-online.html</a> 
 
This works pretty good in the Eclipse testing environment, if you use the version that has been worked out in the comments of this article

My problem is, that it stops to work, if you deploy the report inside the WebViewer on my tomcat. When I am calling the report there (note: it got a onPrepare Script on the report table as shown below) or if I click on the row header (that should normally do the sorting via a hyperlink that links back to the report with changed sorting parameters) the following exception is written to the tomcat console/log: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
SEVERE: org/eclipse/birt/report/engine/script/internal/element/SortConditionImpl
java.lang.NoClassDefFoundError: org/eclipse/birt/report/engine/script/internal/element/SortConditionImpl
at org.eclipse.birt.report.engine.api.script.element.StructureScriptAPIFactory.createSortCondition(StructureScriptAPIFactory.java:94)

at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
...
</pre>
 
I guess this relates to my Script in the onPrepare of the report table: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
sortCondition = Packages.org.eclipse.birt.report.engine.api.script.element.StructureScriptAPIFactory.createSortCondition();

if(params["SortingRow"].value != null && params["SortingOrder"].value!=null)
{
sortCondition.setKey("row[""+params["SortingRow"].value+""]");
sortCondition.setDirection(params["SortingOrder"]);
}
else
{
sortCondition.setKey("row["DOMAINNAME"]");
sortCondition.setDirection("desc");
}

this.addSortCondition( Packages.org.eclipse.birt.report.model.api.simpleapi.SimpleElementFactory.getInstance().createSortCondition(sortCondition.getStructure()) );
</pre>
 
Can someone help me solving this problem? I just searched for the class that couldn't be found (org/eclipse/birt/report/engine/script/internal/element/SortConditionImpl) and it is available in webappsWebViewerExampleWEB-INFplatformpluginsorg.eclipse.birt.report.engine_2.2.2.r22x_v20080107.jar. The question seems to be: why hasn't it / couldn't it be loaded? 
 
Thanks in advance 
Regards Ronny

Ronny,

Can you try the attached report in your tomcat install. It worked in mine.

Jason, 
 
your report works fine for me. Its a nice workaround for sure and I will most likely use it. 
 
Nevertheless I still want to know why mine isn't working

I found someone on the birt newsgroup who seems to look into the problem ... 
 
Thank you
