Spreadsheet integration causes poi error even though all jars are there
I am trying to integrate vaadin spreadsheet with our current vaadin application and we are facing error generated from the add-on. I have added following maven dependency:
<!-- Vaadin Spreadsheet -->
And I have tried it with vaadin 7.6.4 version as well as 7.5.4 both are giving the same error as below:

In addition I have tried adding POI jar dependency in maven as well. Please see our pom.xml file attached.
Looks like the attachment wasn't added.
This shouldn't be a problem related to the vaadin version you're using.
Can you check which version of poi-ooxml jar is maven resolving for your project?
- If you're using eclipse you can see it ProjectExplorer under Libraries/Maven Dependencies or in dependency hierarchy view of the pom.xml.
- If you're using maven from command line you can just run the following in the project folder
mvn dependency:tree -Dincludes=org.apache.poi:poi-ooxml
Version should be 3.12.
If it's not 3.12 please add the result of the dependency:tree command to your answer.
