Whereas lulu.com is being preferred by self-published authors of ebooks, it may put them in trouble as well especially when they submit an epub file, which is not formatted as per the epub publishing guidelines of lulu.com. And, such epubs often results in the ERROR: IOException: Unresolved external XML entity: ‘http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd’ in OEBPS/Text/Section0002.xhtml
Note: Section0002.xhtml is the name of one of the html files in the epub file, which is uploaded to lulu.com, but could not pass lulu.com’s epub validation. In your epub file, this can be different so do not confuse you with the file name.
When you upload file on lulu.com and its validation is failed, then you get a message stating that validation is failed. And, lulu.com also provides you with a .txt file containing reasons due to which validation is failed, and you should fix those errors before resubmitting epub on lulu.com for publishing. However, that .txt file is intended for advanced users who understand html, xhtml, xml, and other such techniques. Hence, if you are not an advanced user then you might not be able to fix issues.
The only solution to resolve the ERROR: IOException: Unresolved external XML entity: ‘http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd‘ in OEBPS/Text/Section0002.xhtml is open the source files and format it as per the guidelines of lulu.com after understanding the reasons given the .txt file provided by lulu.com.
