Hi,
I have a report done with BIRT 3.7.2. This report was working correctly in our RCP application. But to ease the reuse of our styles and images, I wanted to make a Birt library, shared between reports.
My report seems to access correctly to the library in the Birt Designer, as in the preview tab, all is correctly displayed.
But when I try to use the report in my RCP application I have this error :
14 févr. 2013 10:54:23 org.eclipse.birt.report.model.core.LayoutModule loadLibrarySilently
ATTENTION: Syntax error found, and see error details.
Error.DesignFileException.SYNTAX_ERROR - 1 errors found!
1.) org.eclipse.birt.report.model.parser.DesignParserException (code = Error.DesignParserException.FILE_NOT_FOUND, message : The file "reports/designLib.rptlibrary" is not found.)

The rptdesign and the rptlibrary are in the same folder "reports" at the root of my plugin. But I don't know how I can do to make that my report find and use my library ...
Any idea ?

Are you using the viewer? In my example RCP app, if the report and library are in the same folder it works for me. When I change them I set a parameter for the viewer plugin to use as the resource folder. I am doing this in code like:
//get library folder
Bundle mybundle = org.eclipse.core.runtime.Platform.getBundle("org.eclipse.birt.examples.rcpviewer");
URL liburl = FileLocator.find(mybundle, new Path("/rptlib"), null);
String libfolder = FileLocator.toFileURL(liburl).getPath();
HashMap myparms = new HashMap();
HashMap emitmap = new HashMap();
myparms.put("SERVLET_NAME_KEY", "frameset");
myparms.put("FORMAT_KEY", "html");
myparms.put("RESOURCE_FOLDER_KEY", libfolder);
myparms.put("ALLOW_PAGE", "false");
myparms.put("SHOW_PARAMETER_PAGE", "false");
myparms.put("EMITTER_OPTIONS_KEY", emitmap);
WebViewer.display(rpt, browser, myparms);

Yeah ! It's working !
I don't know if it's the best solution but this is what i do :
private class CustomResourceLocator extends ResourceLocatorImplBase {
/** Get the bundle containing the reports resources, in different folders. */
private Bundle reportsBundle = ReportsPlugin.getPlugin().getBundle();
/**
* {@inheritDoc}
*
* Customise the find function to ensure that the resource can be located in our context,
* it means in our Eclipse RCP application.
*/
@Override
public URL findResource(ModuleHandle moduleHandle, String fileName, int type, Map appContext) {
// First, try to locate the resource in our context
URL resourceURL = FileLocator.find(
reportsBundle,
new Path(fileName),
null);
// If the resource is not found, try the standard search
if (resourceURL == null) {
resourceURL = super.findResource(moduleHandle, fileName, type, appContext);
}
return resourceURL;
}
}
And this resource locator is set to our EngineConfig.
