Runtime error in java with apache POI

Question

I get the error:

java.lang.NoSuchMethodError: org.apache.xmlbeans.XmlOptions.setSaveAggressiveNamespaces()Lorg/apache/xmlbeans/XmlOptions;
at org.apache.poi.POIXMLDocumentPart.<clinit>(POIXMLDocumentPart.java:56)

from the line 56:

public static Workbook wb = new XSSFWorkbook();

I just had to re-link my library, but all i did was move all the files and reset the build path to where i moved the files to, and removed the old one.

Answer 1

java.lang.NoSuchMethodError: org.apache.xmlbeans.XmlOptions.setSaveAggressiveNamespaces()Lorg/apache/xmlbeans/XmlOptions;

This statement says that you have mismatch(incompatible) of jars. Make sure you have supported version of jars.
