Question

I am using com.lowagie.text.xml.SAXiTextHandler to convert XML to PDF using iText(v – 2.1.7). I get the below error although i can see that i am using the tags correctly. Verified that the XML formed is valid and i can view it in browser w/o errors. Code fails when trying to do the a parser.parse(….). I have checked the way i have written the tags and it looks fine to me. I have basically added table tags, containing row tags which inturn contains cell tags.
Cell tags have a single paragraph tag inside it (or) sometimes a paragraph and a chunk tag within the paragraph. Is there any way I can get to where this issue happens?

* Removed all the paragraph tags from the XML and tried again. It is returning the same error – Here is the new XML used – http://pastebin.com/hmyPcGDw *

* Even this simple xml file is generating the same exception now – http://pastebin.com/89U9vybt *

To me it looks like an issue with com.lowagie.text.xml.SAXiTextHandler. Any help ?

java.lang.ClassCastException: com.lowagie.text.Paragraph cannot be cast to com.lowagie.text.Table

Answer 1

Thats because you have some white space before and after your xml tags (more precisely the white spaces after the <table> tag). I tried with your example and i had the same exception. I made a copy/paste of your xml code into eclipse (or notepad++) i formatted it (that removes all the unwanted white space) and then i tried again and the problem was solved! the pdf is well generated!
