I'm trying to generate a very simple report, the report can be successfully generated using iReport tools preview. But in the Java module calling to JasperFillManager.fillReport(InputStream, hashMap, Connection), an unknown exception thrown and the description cannot provide any idea. The exception is net.sf.jasperreports.engine.JRRuntimeException: Unknown hyperlink target 0 Does anyone know what is the cause of the problem? Many thanks. Here's the stack trace for the error. net.sf.jasperreports.engine.JRRuntimeException: Unknown hyperlink target 0 at net.sf.jasperreports.engine.JRHyperlinkHelper.getLinkTarget(JRHyperlinkHelper.java:269) at net.sf.jasperreports.engine.base.JRBaseTextField.normalizeLinkTarget(JRBaseTextField.java:313) at net.sf.jasperreports.engine.base.JRBaseTextField.readObject(JRBaseTextField.java:377) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at java.io.ObjectStreamClass.invokeReadObject(ObjectStreamClass.java:974) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1849) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1753) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) at java.util.ArrayList.readObject(ArrayList.java:593) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at java.io.ObjectStreamClass.invokeReadObject(ObjectStreamClass.java:974) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1849) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1753) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:1947) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1871) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1753) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.readArray(ObjectInputStream.java:1667) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1323) at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:1947) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1871) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1753) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:1947) at java.io.ObjectInputStream.defaultReadObject(ObjectInputStream.java:480) at net.sf.jasperreports.engine.base.JRBaseReport.readObject(JRBaseReport.java:742) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at java.io.ObjectStreamClass.invokeReadObject(ObjectStreamClass.java:974) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1849) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1753) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1329) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) at net.sf.jasperreports.engine.util.JRLoader.loadObject(JRLoader.java:194) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:376) Post Edited by ivanyiu at 04/14/2010 05:27 Post Edited by ivanyiu at 04/14/2010 05:28
