Ask Question What version of Apache Tomcat are you using? What other XML parsers are on your classpath? – Gagravarr Oct 9, 2018 at 15:16 This is likely caused by having an ancient XML parser on your classpath - eg eclipse.org/forums/index.php/t/781657 - can you upgrade to xerces 2.12.0? – PJ Fanning Oct 9, 2018 at 19:12 Thank you very much everyone! You are right, the problem was an XML parser (xalan) in my case, Tho, doesn't apache poi have its own xml parser? – sticky_elbows Oct 10, 2018 at 6:37 Apache POI like most Java projects uses docs.oracle.com/javase/8/docs/technotes/guides/xml/jaxp/… - basically, it is up to the user to ensure they have their JVM set up correctly – PJ Fanning Oct 10, 2018 at 23:13 All seems to be working now after reading this: developerblogging.blogspot.com/2013/04/… . If you will scroll down to the bottom. So I added the above line to my eclipse.ini file. Restarted and was finally able to run tomcat. – DoesEatOats Oct 27, 2019 at 14:47
