I had problems with Netbeans project from trunk. Their was a lot of
unresolved dependencies. I had to create my own project from trunk sources.
I had following troubles when building it:
1. In file SqlXmlUtil.java, Netbeans couldn't suggest a package for
OutputProperties. Later I found that it was in org.apache.xalan.templates
package
2. It couldn't suggest where to find org.apache.xpath.XPath class
constructor with *XPath*(java.lang.String exprString,
SourceLocator
<../../../javax/xml/transform/SourceLocator.html> locator,
PrefixResolver
<../../../org/apache/xml/utils/PrefixResolver.html> prefixResolver,
int type,
ErrorListener
<../../../javax/xml/transform/ErrorListener.html> errorListener)
syntax. Later I figured out that it was
http://xml.apache.org/xalan-j/apidocs/org/apache/xpath/XPath.html#constructor_detail
So there is two imports missing in source code
3. Reflection problems:

I found this
http://java.sun.com/docs/books/tutorial/reflect/member/methodTrouble.html.
I will try to do it on my own just for practice. But that is not a
solution. That what I will code is performance aware. I never
re-factored reflection related code; the reflection API stuff. Only
for PHP 5 reflection API. So help from community will be needed. John
