JIRA plugin v2 Apache POI XMLEventFactory: Provider com.ctc.wstx.stax.WstxEventFactory not found

Hi,

I've added the Apache POI dependency to my JIRA plugin in order to add the ability to create Excel spreadsheets.

I've been able to create a simple spreadsheet with data populated in cells using the HSSFWorkbook.  But when I change my code to use the XSSFWorkbook (instead of HSSFWorkbook, all other code unchanged), then I'm getting the following run-time error:

java.util.ServiceConfigurationError: javax.xml.stream.XMLEventFactory: Provider com.ctc.wstx.stax.WstxEventFactory not found 

// Workbook workbook = new HSSFWorkbook(); // this works
Workbook workbook = new XSSFWorkbook(); // this gets the run-time error

 

Can this be some sort of jar conflict?
Here is the Apache POI dependency that I added to my pom.xml:

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.15</version>
</dependency>

 I looked up the jar that has the com.ctc.wstx.stax.WstxEventFactory class and it belongs to wstx-asl-x.x.x.jar ... do I need to add a dependency to this?  Or add it to the Import-Package section?

Thanks in advance for any help!

I found the solution!  I added another dependency (a jar library which contains the com.ctc.wstx.stax.WstxEventFactory class) so the following is what I needed in my pom.xml:

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.15</version>
</dependency>
<dependency>
    <groupId>com.ctc.wstx</groupId>
    <artifactId>woodstox-osgi</artifactId>
    <version>3.2.1.1</version>
</dependency>
