It is clear that poi3.15 can't run at resin4, but poi3.9 can do it. I use test code from poi help, can call it from a jsp. Test3_9 worked but Test3_15 failed like as my code.
Maybe it is a good idea down to 3.9 .

I made a web application which is correct in tomcat. When I put it into resin4, everything is good except POI3.15. It became not to read xlsx, but xls reading is still correct. Error info is the next line. java.lang.NoClassDefFoundError: Could not initialize class com.sun.org.apache.xml.internal.serializer.ToXMLStream I check every jar in POI and tomcat, but can't find the class. I don't know whether it is bug of POI or not when I writing the mail. I am puzzled, please give me some advice.
