Question

I am trying to write a program which write the data in Excel. But i keep getting an error which is shown below:

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.xmlbeans.XmlOptions.setSaveAggressiveNamespaces()Lorg/apache/xmlbeans/XmlOptions;
    at org.apache.poi.POIXMLDocumentPart.<clinit>(POIXMLDocumentPart.java:56)
    at wriExcel.main(wriExcel.java:19)

On finding the solutions, I could only find that I should use XMLBeans 2.0 or higher. But, I am using xmlbeans 2.3.0 . Is there any other reason for this error.

Answer 1

使用xmlbeans-2.6.0.jar可以解决我的问题...！

Answer 2

This error might be because required needed for the project is not there so you have to download jar and then add that jar to your classpath here is the link

find out which jar you need

Answer 3

Use the xmlbeans jar file shipped with PIO libraries, and avoid to download from any other source as there will be jar file conflicts.

You can find the xmlbeans under "ooxml-lib" shipped with PIO.
