http://nagoya.apache.org/bugzilla/show_bug.cgi?id=12707 Problems with Component class name in JSP [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |ASSIGNED ------- Additional Comments From [EMAIL PROTECTED] 2002-09-23 19:48 ------- This looks more like a problem with the underlying JDK (J2SE 1.4.1). The attached program uses Introspector.getBeanInfo() to get the BeanInfo associated with the class specified on the command line, and then enumerates the PropertyDescriptor[] returned by BeanInfo.getPropertyDescriptors(). When I specify "test.Component" as the class to be introspected, I am getting the following wrong result, which is identical to introspecting "java.awt.Component": java Introspect test.Component class: test.Component pd.length: 7 0: public java.awt.Color java.awt.Component.getBackground() class java.awt.Color 1: public boolean java.awt.Component.isEnabled() boolean 2: public boolean java.awt.Component.isFocusable() boolean 3: public java.awt.Font java.awt.Component.getFont() class java.awt.Font 4: public java.awt.Color java.awt.Component.getForeground() class java.awt.Color 5: public java.lang.String java.awt.Component.getName() class java.lang.String 6: public boolean java.awt.Component.isVisible() boolean This would explain why you are getting this compile-time exception when accessing test-error/test.jsp: org.apache.jasper.JasperException: Cannot find any information on property 'data' in a bean of type 'test.Component' However, when i specify "test.component" (with a lower-case 'c') as the class to be introspected, I get the expected result: java Introspect test.component class: test.component pd.length: 2 0: public final native java.lang.Class java.lang.Object.getClass() class java.lang.Class 1: public java.lang.String test.component.getData() class java.lang.String which is why accessing test-work/test.jsp works just fine.
