poi-ooxml-schemas-3.17.jar

Hope you can help me

This error typically occurs when you have a library version mismatch. — Sam Orozco

Build Path != Deployment / Runtime Path. What jars do you have at runtime? Which ones did you miss? What happens when you add them? — Gagravarr

My librairies were not in the project.xml file, so tomcat coule not load them, even if the project was compiled... Tanks for help — Tristan Le Gacque
