Hi All

 

I am using iReport 1.3 and Java 1.5 and when I want to compile an empty report I get the following error:

 

java.lang.VerifyError: class org.apache.xerces.jaxp.datatype.DurationImpl overrides final method . at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:604) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:123) at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) at java.net.URLClassLoader.access+100(URLClassLoader.java:56) at java.net.URLClassLoader+1.run(URLClassLoader.java:195) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:289) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:279) at java.lang.ClassLoader.loadClass(ClassLoader.java:235) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:302) at org.apache.xerces.impl.dv.xs.AbstractDateTimeDV.<init>(Unknown Source) at org.apache.xerces.impl.dv.xs.DurationDV.<init>(Unknown Source) at org.apache.xerces.impl.dv.xs.XSSimpleTypeDecl.<clinit>(Unknown Source) at org.apache.xerces.impl.dv.xs.SchemaDVFactoryImpl.createBuiltInTypes(Unknown Source) at org.apache.xerces.impl.dv.xs.SchemaDVFactoryImpl.<clinit>(Unknown Source) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:415) at java.lang.Class.newInstance0(Class.java:322) at java.lang.Class.newInstance(Class.java:275) at org.apache.xerces.impl.dv.ObjectFactory.newInstance(Unknown Source) at org.apache.xerces.impl.dv.SchemaDVFactory.getInstance(Unknown Source) at org.apache.xerces.impl.dv.SchemaDVFactory.getInstance(Unknown Source) at org.apache.xerces.impl.xs.SchemaGrammar$BuiltinSchemaGrammar.<init>(Unknown Source) at org.apache.xerces.impl.xs.SchemaGrammar.<clinit>(Unknown Source) at org.apache.xerces.impl.xs.XMLSchemaValidator.<init>(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.configurePipeline(Unknown Source) at org.apache.xerces.parsers.XIncludeAwareParserConfiguration.configurePipeline(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at org.apache.commons.digester.Digester.parse(Digester.java:1647) at net.sf.jasperreports.engine.xml.JRXmlLoader.loadXML(JRXmlLoader.java:238) at net.sf.jasperreports.engine.xml.JRXmlLoader.loadXML(JRXmlLoader.java:225) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:213) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:167) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:151) at net.sf.jasperreports.engine.JasperCompileManager.compileReportToFile(JasperCompileManager.java:107) at it.businesslogic.ireport.IReportCompiler.run(IReportCompiler.java:529) at java.lang.Thread.run(Thread.java:566)

I have just discovered that if I use Java 1.6 that the problem is solved. It was unclear to me that iReport 1.3.0 was designed for Java 6
