1. Right Click Your project in Eclipse.

2. Select properties from popup menu. It will open dialog box titled 'Properties for your_project_name'

3. Select Java Build Path on left hand side tree.

4. Then select Libraries tab on right hand side tabs.

5. Use 'Add External JARs..' to add jasper_xxxx.jar

 

I hope that will help.

look, i finish my report in IReport, and it gave 3 files, one

ejemplo001.jrxml ; other ejemplo001.jasper and the last ejemplo001_1172239796670_212229.java

i don't know why the IReport generate a lot of file with java extention, i mean i made another examples with IReport, and every time i run my report, the IReport genera me another file with Java extention, i suppost that it was because i made some changes, and the program didn't write over; but my real question is What i have to wait when i running my program with eclipse, it should appear the same view that appear with IReport ????, because i don't have error, now, but how do i know if it's rigth??, what have i to do after export my IReport file ???,

Any programmer knows that the load times aren't the same simply because you are using two totally different software to load/display a report.

 

This has nothing to do with jasperreports and it just indicates your lack of knowledge of how software works. I am always willing to help out here but if your basic knowledge of Software is so bad then dont bother asking questions about computer software let alone Java libraries or Java.
