268 Chapter 12: Building Custom CFXAPI Tags
After you implement a main method as described previously, you can debug your Java CFX tag
using an interactive, single-step debugger. Specify your Java CFX class as the
main class, set
breakpoints as appropriate, and begin debugging.
Debugging classes example
The following example demonstrates how to use the debugging classes:
import java.util.Hashtable ;
import com.allaire.cfx.* ;
public class OutputQuery implements CustomTag {
// debugger testbed for OutputQuery
public static void main(String[] argv) {
try {
// initialize attributes
Hashtable attributes = new Hashtable() ;
attributes.put( "HEADER", "Yes" ) ;
attributes.put( "BORDER", "3" ) ;
// initialize query
String[] columns =
{ "FIRSTNAME", "LASTNAME", "TITLE" } ;
String[][] data = {
{ "Stephen", "Cheng", "Vice President" },
{ "Joe", "Berrey", "Intern" },
{ "Adam", "Lipinski", "Director" },
{ "Lynne", "Teague", "Developer" } } ;
DebugQuery query =
new DebugQuery( "Employees", columns, data ) ;
// create tag, process debugging request, and print results
OutputQuery tag = new OutputQuery() ;
DebugRequest request = new DebugRequest( attributes, query ) ;
DebugResponse response = new DebugResponse() ;
tag.processRequest( request, response ) ;
response.printResults() ;
}
catch( Throwable e ) {
e.printStackTrace() ;
}
}
public void processRequest(Request request, Response response) throws
Exception {
// ...code for processing the request...
}
}
