------------------------------------------------------------ -----------
Hello,
I think I have a similar problem, I get my classes not loaded to a
ScriptedDataSet:
in a servlet I do the following:
IRunAndRenderTask task = birtReportEngine.createRunAndRenderTask(design);
contextMap.put(EngineConstants.WEBAPP_CLASSPATH_KEY,
sc.getRealPath("classes")); // sc = ServletContext
task.setAppContext(contextMap);
Map appContext = task.getAppContext();
for (Iterator iterator = appContext.entrySet().iterator();
iterator.hasNext();) {
Entry entry = (Entry) iterator.next();
log.debug("AppContext: " + entry.getKey() + " - " + entry.getValue());
}
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat(RenderOptionBase.OUTPUT_FORMAT_PDF);
options.setOutputStream(resp.getOutputStream());
task.setRenderOption(options);
task.run();
In a report, I use a ScriptedDataSet, which tries to instantiate a POJO from
webapp:
<script-data-set name="DataSet" id="19">
<property name="dataSource">DataSource</property>
<list-property name="resultSet">
....define some properties...
</list-property>
<method name="open"><![CDATA[currs = new
Packages.com.equirion.printing.CurrencyListPrintingDataSet() ;]] ></method>
</script-data-set>
This produces the followin error:
WARNING: A BIRT exception occurred: Error evaluating Javascript expression.

another Test in my PrintServlet:
I tried to load the class with a local loader and with the Loader used in
the IReportEngine, this produces the following output:
ClassLoader loaderLocal = this.getClass().getClassLoader();
ClassLoader loaderBirt = birtReportEngine.getClass().getClassLoader();
log.debug("Classloader PrintServlet:" + loaderLocal);
log.debug("Classloader birtReportEngine:" + loaderBirt);
try {
loaderLocal.loadClass("com.equirion.printing.CurrencyListPrintingDataSet ");
} catch (ClassNotFoundException e1) {
log.error("Local Loader class not found");
}
try {
loaderBirt.loadClass("com.equirion.printing.CurrencyListPrintingDataSet ");
} catch (ClassNotFoundException e1) {
log.error("Birt Loader class not found");
}
