问题描述
我在iReport中有项目,我想在jasper工作室中构建它,因为我使用一些外部jar文件来转换日期,但是在jasper工作室我无法使用它们,我在右键单击项目文件夹>属性> java build path>库>添加外部JAR ..
,当我想查看报告预览时出现错误:
I have project in iReport,I want to build this in jasper studio,in that I use some external jar file to convert date,but in jasper studio I cant use them,I add those jar file in right click on project folder > properties > java build path > libraries > add External JARs..
,iI get error when i want to see report preview :
net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:
1. com.ghasemkiani.util.icu.PersianDateFormat cannot be resolved to a type
value = new com.ghasemkiani.util.icu.PersianDateFormat("yyyy/MM/dd").format(((java.sql.Timestamp)field_ORDERDATE.getValue())); //$JR_EXPR_ID=9$
<---------------------------------------->
2. com.ghasemkiani.util.icu.PersianDateFormat cannot be resolved to a type
value = new com.ghasemkiani.util.icu.PersianDateFormat("yyyy/MM/dd").format(((java.sql.Timestamp)field_ORDERDATE.getOldValue())); //$JR_EXPR_ID=9$
<---------------------------------------->
所以,我的问题是:如何添加外部jar文件并使用它?
so,my question is : how can I add external jar file and use it?
推荐答案
将jar文件添加到构建路径后,必须重新启动Jasper Studio。
After you have added jar file to build path you have to restart your Jasper Studio.
