I have a method named renderOutput when the code reaches the task.run it throws the below error.
This happens when we are trying for a bar chart . Same method works Works fine with the tabular format.
***************************************************************
try {
task = birtReportEngine.createRunAndRenderTask(ireportrunnable);
task.setAppContext(map);
task.setLocale(Locale.ENGLISH);
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_HTML);
options.setImageDirectory(servletContext);
// options.setHtmlPagination(true);
options.setBaseImageURL(contextPath + ORMReportConstants.IMAGE_DIR);
options.setImageHandler(new HTMLServerImageHandler());
options.setOutputStream(outStream);
task.setParameterValue("AuthorName", "Dale DeMott");
task.setRenderOption(options);
task.run();
} catch (Exception e) {
e.printStackTrace();
} finally {
task.close();
}

Is that the entire stack trace? Do you have any other parameters that aren't getting set, possibly? If no, can you recreate this issue with a report that uses the sample database and attach your java file and report design file? Thanks.
