Bug 369567

Description Alessio Pollero 2012-01-24 13:29:20 EST

Build Identifier: Version: 3.7.1 Build id: M20110909-1335

I have created a birt extension functions plugin like the following : http://code.google.com/a/eclipselabs.org/p/birt-functions-lib/, inside the library i have implemented a function that get a company image from the file system with this code : 


private class getCompanyLogo implements IScriptFunctionExecutor {

		@Override
		public Object execute(Object[] arguments, IScriptFunctionContext context)
				throws BirtException {
			// Argument : ReportContext
			if(arguments.length > 0) {
				Object rcArgument = arguments[0];
				if ( !(rcArgument instanceof IReportContext) ) 
			        throw new BirtException("Report Context object is not instance of IReportContext in " + this.getClass().getSimpleName() );
			        
				IReportContext reportContext = (IReportContext) rcArgument;
				//Get Report Name
				java.io.File report = new java.io.File(reportContext.getReportRunnable().getReportName());    
				java.net.URL uLogo = reportContext.getResource("CompanyLogo.png");
				java.io.File file = null;
				//If exist get the Company image from resource
				if(uLogo != null)
					file = new java.io.File(uLogo.getFile());
				
				//Try to get CompanyLogo image from the current folder
				java.io.File f = new java.io.File("CompanyLogo.png");
				if(f.exists())
					file = f;
				
				//Try to get the CompanyLogo from report related file
				String path = report.getPath();
				String[] name = report.getName().split("\\.");
				f = new java.io.File( ((path != null) ? path : "") + ((name.length > 0) ? name[0] : "") );
				if(f.exists())
					file = f;
				
				if(file != null && file.exists()) {
					try {
						java.awt.image.BufferedImage img = javax.imageio.ImageIO.read(file);
						return img;
					} catch (java.io.IOException e) {
						throw new BirtException(String.format("Error loading Company Logo image : %s!",e.getMessage()));
					}
				}
			} else 
				throw new BirtException("No arguments for function getCompanyLogo(), you must pass ReportContext !");
			
			return null;
		}


When i call this function from a report Script(OnCreate of a Dynamic image):

importPackage(Packages.java.io);
importPackage(Packages.java.lang);
importPackage(Packages.java.net);
importPackage(Packages.javax.imageio);


var img = MyFunctions.getCompanyLogo(reportContext);
var bas = new ByteArrayOutputStream();
ImageIO.write(img, "png", bas);
this.data = bas.toByteArray();


i get the following error and i don't know why ... Looking in debug mode of the report the object BufferedImage is correclty passed by the function..

StackTrace of the error :
