throwcode

Hi ajithn, we have been throught it and through it but have found on conflicting jars. I guess it could be buried somewhere in the IDE (we use NetBeans). For now we have moved on to other components and will come back in a week with a fresh pair of eyes. Our fall back strategy will be to de-install 3.7.1 and reinstall the older version that we know works for us. Thanks for your help. TC

Hi ajithn, thanks for the info. Unfortunately you seem to identified another problem. I re-dwonloaded the jar 'jasperreport-3.7.1.jar' and compare the two side by side. They both contained 'net.sf.jasperreports.components.ComponentsExtensionsRegistryFactory.class' And both still result in the following error: SEVERE: java.lang.NoSuchMethodError: net.sf.jasperreports.engine.component.DefaultComponentManager.setDesignConverter(Lnet/sf/jasperreports/engine/component/ComponentDesignConverter;)V at

java.lang.Thread.run(Thread.java:619) A slightly different error than what I think you're addressing. We have only one version of JasperReports and iReports so I don't see a conflict with an older version being the issue - we created some simple test reports directly from the latest of each - worked in iReports and failed in Java execution? I appreciate the input, hope someone can point me in the right direction. Thanks TC

Hi, did anyone find a solution to this error. We just upgraded to JasperReports and iReport 3.7.1 and we now receive this error on ALL reports. They all work in iReports but fail with the above mentioned error in java execution! Even very simple reports created new in iReports 3.7.1, compiled by iReport 3.7.1 and used in java as *.jasper as file in InputStream. Any assistance would be greatly appreciated. TC

Hi, I would like to provide my users with the ability to define custom headers for predefined reports. Sending the headers as parameters is easy but I would also like to allow them to decide on font size, bold or italic. My problem is that I do not know how to set the font attributes (size, bold, and italic) dynamically. I can preset the textField property sheet | font tab to some default settings but have not figured out how to override these attributes in an expression statement. Any assistance would be greatly appreciated. TC
