From time to time, I update the examples based on reader feedback about bugs. It's my intention to only update the examples when they do not follow the specifications, as opposed to add work-arounds for specification-compliance bugs in various containers. In the latter case, I instead inform the vendor about the problem, in the hope that these examples will have a positive impact on container-compliance over time.

Changes compared to version 1.0

• Added createStatement(int, int), prepareStatement(String, int, int), prepareCall(String, int, int), getTypeMap() and setTypeMap() to ConnectionWrapper.java so it compiles with a Java 2 compiler.
• Removed incorrect </jsp:useBean> tag in ch8/userinfoinput.jsp and ch12/clientscript.jsp.
• Corrected syntax errors in web.xml for the <security-role> elements.
• Reset the tag handler properties that can be set using nested elements, to avoid problems in containers that reuses tag handler instances (such as Orion). This has been fixed in EncodeURLTag, RedirectTag, and DBTag.
• Changed all getXXX(String name) methods in the Column subclasses to do a case-insensitive lookup, since some databases (e.g. Oracle) ignores the case used for column names in the SELECT statement when it creates the ResultSet.
