问题 I'm getting a java.lang.SecurityException: class "org.apache.poi.POIXMLDocument"'s signer information does not match signer information of other classes in the same package between the BIRT core jar and an Apache POI jar, as described by this BIRT bug report. It has been stated in the bug report that this can be fixed by upgrading BIRT, however when I do that I run into another runtime bug which can only be solved by downgrading. Thus, as it stands I am in a little bit of a pickle here. This

问题 I'm trying to learn how to use Apache POI with a small project. I want to use Excel to create 'room layouts' by using colour-coded cells, and load the data into a Java program. I think understand how to access the colour properties of a cell, but what I'm asking is: Is it possible to access the colour of a blank cell (no data or value), or does a cell need to have data in order for Apache POI to read it?

问题 I am iterating over XWPFParagraph instances coming from an XWPTDocument instance (using the "getParagraphs()" method) Is there a way to retrieve the page numbers where each paragraph is located from the XWPFParagraph instances? 回答1: To eventually turn Gagravarr's comment into a proper answer: No, this is not possible.
