I am using struts and weblogic for development . I am also using jakarta - POI to develop custom excel files.
I changed poi version 1.5 to 2.5 due to client requirement. It was working fine in the old version.
But when I deploy the application I get the error -
Struts error - Attribute "preprocess" must be declared for element type "ac
[Thread-7] ERROR digester.Digester - Parse Error at line 345 column 24: Attribute "preprocess" must be declared for element type "action". org.xml.sax.SAXParseException: Attribute "preprocess" must be declared for eleme nt type "action". at weblogic.apache.xerces.framework.XMLParser.reportError(XMLParser.java :1301) at weblogic.apache.xerces.validators.common.XMLValidator.validateElement AndAttrib utes(XMLValidator.java:3778) . . .
and then the complete dump of validation.xml file
I am unable to find out that. Please help me for that.
