Added: jasper34/generator/org/apache/jasper34/jsptree
BeanRepository.java TagLibraries.java
TagLibraryInfoImpl.java
Log:
Moved from generator, are basically informations associated with the
jsp page.
The TagLibraries is important because the parser will depend on it
( it needs to validate and change behavior based on the declarations )
