I am reading the book: "Beginning XML 4th Edition". In Chapter 4, we are to create a DTD using Codeplot editor (http://codeplot
). I typed in the DTD example provided, saved it, and clicked on "validate" the document. It came back with this error message:
"Unable to instantiate parser: Java heap space"
What does this mean and how to fix? (I have a PC running XP Professional and use IE 5.0+.) Since Codeplot editor is used throughout Chp. 4-6, I am stuck without it working.
