Appending to data files from java code

I need to write an application that appends data to an exisiting data file.  From what I can determine, all of the Java xxxOutputStream classes want to create a new file rather than appending.

I have to believe this is something I'm overlooking, rather than something the Java group forgot.

You're right - you overlooked it! Check out java.io.RandomAccessFile for some answers.

RandomAccessFile allows you to choose where in a file you want to write (or read) some bytes, text and so on. To append data to a file just use length() to get the file size and then write the data at that point.
