I'm using ColdFusion MX7 to perform a CFEXECUTE on some Java 6 code. Unfortunately sins CF7 does not work under JDK 6 I must do it this way. My problem is that when an exception happens in the Java code if I call a printStackTrace on the exception the CFEXECUTE command hangs. Coldfusion eventually times out but the java process cont...
I'm using BufferedReader and PrintWriter to go through each line of an input file, make a change to some lines, and output the result. If a line doesn't undergo a change, it's just printed as is to the output file. For some reason however, the process ends prematurely. The code looks something like this: BufferedReader in = new Buffered...

When dividing by 1000 I sometime run across a bug that doesn't do the division "correctly". For example, when dividing 90.55 by 1000 instead of getting .09055 I get .090549999999. <c:out value="${bean.paPrice / 1000}" /> Why is this happening? Is this a result of floating point math?

I have some jar files that will be distributed to clients that are using log4j for logging. My question is should I include a log4j.xml configuration in the jar file or have the client provide one if they want logging? My feeling is to leave the log4j.xml configuration file out of the client jars, since the apache jar files all come wi...

There is a (non-mandatory) OneToOne association defined between these entities, and they share the Person primary key (i.e. PERSON_ID is defined in both Person and Billing, and it is a foreign key in the latter). When doing a select on Person via a named query such as: ...

I'm creating a JasperReport using iReport, and as such, I'm limited* to one SQL query. I have a table 'statistics', with a 'name' (VARCHAR), 'count'(INTEGER), and 'datetime'(DATETIME) columns. It is simple enough to get the sum of the 'count' column when the 'name' was "test" for the last day, and similarly for the last week, and month ...
I have some Java user interface controls that I want to host in my .NET application as I can't afford to rewrite them. How can I do that? Do I need to wrap them up in COM? How do I do that? I want the component to sit on a form with other components written in .NET. ...

For a remote application that needs to monitor the logged events, I'd like to just swap in a logger that logs to a buffer and then retrieve the buffer, rather than refactor the class...
I have to port some C# code to Java and I am having some trouble converting a string splitting command. While the actual regex is still correct, when splitting in C# the regex tokens are part of the resulting string[], but in Java the regex tokens are removed. What is the easiest way to keep the split-on tokens? Here is an example of ...
