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..
