Looks like both POI 3.15 and 3.6 tried to load, but Maven correctly rejected 3.6 due to a duplicate version conflict. However, if the library that tried to import 3.6 is expecting a class from 3.6 that was removed or renamed in 3.15, you would likely get some kind of Class error. Seems to be from it.habble:habble-ejbs:ejb based on your dependency tree. Either remove that dependency or fork and rebuild that dependency with POI 3.15 to avoid mixed versions.
You also use both org.apache.xmlbeans 2.3 and 2.6, and maven rejects 2.6. Either version should work, but 2.6 is preferred. https://poi.apache.org/overview.html#components On Jan 25, 2017 02:10, "Christian Castelli" <christian.caste...@habble.it> wrote: > It's important to notice that this exception is occasionally thrown, so > it's Maven related but I cannot understand what causes differences between > builds... > > On 2017-01-25 10:09 (+0100), Jörn Franke <jornfra...@gmail.com> wrote: > > Might be that one dependency loads a different version of the parser? > > > > > On 25 Jan 2017, at 10:04, Christian Castelli < > christian.caste...@habble.it> wrote: > > > > > > Hi all, > > > when I deploy my web application on a different machine other than > mine I receive this Exception when I try to open XLSX files with > > > > > > Workbook wb = WorkbookFactory.create(new File(IVENTORY_TEMPLATE)); > > > > > > java.lang.ClassCastException: org.apache.xerces.parsers. > XIncludeAwareParserConfiguration cannot be cast to > org.apache.xerces.xni.parser.XMLParserConfiguration > > > > > > I'm using POI 3.15 in a multi-module maven web application (web, ejb, > jpa) packaged as an EAR archive.
