We use SAX to parse XML because it does not require the entire XML document to be read into memory in order to parse a single value. I read many articles that insisted SAX can only be used to parse/decode XML and not create it. Is this true? |
The idea of unit testing is to test small sections of code with each test. In an event based system, one form of unit testing you could do, would be to test how your event handlers respond to various events. So your unit test might set an aspect of your program into a specific state, then call the event listener method... |

You may need to pay, but when I switched from Register.com to goDaddy.com I paid a very small amount to transfer (like $10) and also renewed the domain for another 2 years. (This turned out to be much cheaper than renewing with Register.com) |
You could push a byte into a pipe opened as non-blocking to signal to the other thread when its done, then use a non-blocking read to check the status of the pipe. |
No, it isn't true, you can encode XML to any Writer in Java using something similar to:

I would recomment to shell out call to "xsltproc", which comes with the libxslt libraries in linux and does the work.
Or if you are using JRuby by any chance, then you have several xslt parsers for java that you can really really easily use from your ruby program. |
Why not overload the getEmployeeName(??) method? <br>
<br> getEmployeeName(int BatchID)<br>
getEmployeeName(object SSN)<br>
getEmployeeName(String Email)<br>
etc.
Seems a good 'many' approach to me.

I think it would be much better to show this with lexical variables as file handlers

How about using SQLlite instead of access for db? I have never used it but have heard that its good for some light weight and quick db tasks. |
In general, no you really don't want to use protected data members. This is doubly true if your writing an API. Once someone inherits from your class you can never really do maintenance and not somehow break them in a weird and sometimes wild way. |

I use them. In short, it's a good way, if you want to have some attributes shared. Granted, you could write set/get functions for them, but if there is no validation, then what's the point? It's also faster.

Add the job, with its relevant parameters, to a job queue table.

Using the Unix philosophy of "gluing together many small tools" I'd suggest writing a short script that calls gcc with the -M (or -MM) and -MF < outfile > options (As detailed [here][1]).

Not sure if I understand your point right, I suppose you need to delete old classes before running sablecc because some of them would not be eventually created in new run.
It is probably best to write short [Ant][1] build.xml with the target, which first removes the classes (Ant delete task) and then runs sablecc (A... |

Depends on the host also. If you go with a company like BlueHost, for example, they'll give you free domain transfers from the losing registrar. I think, in fact, they may give you free transfers. They will and ask if you want to renew your domain with them which will cost you, though. |

At MediumCo, we strip proprietary data out of our production data in Test and Dev. It has hurt us a little in the past to not have exactly-representative data, but the clients have asked about this point before, and it's usually not an issue, as the environments are populated with a lot of fake proprietary data. |
