- Bugzilla Bug (s) Resolved:
123705 ClassCastException when trying to cast IReportContext.getHttpServletRequest() to HttpServletRequest
- Description:
BIRT supports user uses its own classes in the script (java event handler). The classes are loaded by BIRT in following sequence:
1. system class loader
2. user defined app classloader (set in the app context, it is the WebApploader in web-viewer)
3. JARs defined in the system properties (scritpt lib in WebViewer)
4. JARs defined in the report design
so, the classes defined in the later loaders can use the classes defined in the early loader. The parent relation ship are:
system class loader is the root loader
app class loader is the parent of property loader
property loader is the parent of design loader.
