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.

Thanks.

I don't know that editor but the error message seems to indicate it is a Java application (or is using Java for parsing/validation) and does not have enough memory to perform the validation.

That is what I was thinking but unsure if there is some setting on my computer that needs changing or some Java download I need to go out to grab? The DTD I am validating is only about 15 lines long so out of memory sees unlikely.

Is that editor a Java application that you start?
Then you might want to try to start it with more memory http://java.sun.com/javase/6/docs/te...dows/java.html
