1. When IREPORT generates a Chinese PDF report, set: 1) Add ITEXT Chinese package in the lib directory 2) PDF Encoding Select unigb-ucs2-h (Chinese Simplified) PDF Font Name STSONG-Light (you can use View-> Report FONTS One Solved) 2. Ireport sometimes displays the solution in the database: 1) Element: Setting: Print When Details overflow; stretch overflow 2) Field is not enough
3. Dori.jasper.Engine.jrexception: Error Loading Object from File: D: /jakarta-tomcat-4.0.1/jakarta-tomcat-4.0.1/webapps/safe/safe1.jasper
The version of the new JasperReport is 0.5.2, Ireport is 0.5.0, you will change your search path in your search path.
4. A period of test code: package test;

Using the MySQL database to generate PDF Report, displayed in Tomcat: <% @ Page Import = "Dori.jasper.Engine. *"%> <% @ Page import = "java.util. *"%> <% @ Page import = "java.io. * "%> <% @ Page import =" java.sql. * "%> <% File reportfile = new file (Application.getRealPath (" / reports / mydoc5.jasper "); map parameters = new hashmap (); .
