Java toRealPath() fails(Jasper)
I am currently tying to use jasper report in Java project , i was able to design report and compile jasper but getting issue when running report , i am currently facing issue with loading subreports and images. Below is the folder structure of jasper reports
- com(package of applications)
- net(package of jasper)
- resources
- jasperreport
- main.jasper
- subreport1.jasper
- jasperreport
in main.jasper ( i am referring to images and subreport1.jasper) , below is the code , this throws exception as byte data not found
<subreportExpression><![CDATA["/resources/jasperreport/subreport1.jasper"]]></subreportExpression> I tried with below approach , this throws exception as byte data not found
<subreportExpression><![CDATA["subreport1.jasper"]]></subreportExpression> Below is code that works
<subreportExpression><![CDATA["resources/jasperreport/subreport1.jasper"]]></subreportExpression> Though above mentioned approach works but i get warning
Failed to resolve real path for file resources/jasperreport/subreport1.jasper
I did check code of Jasper it tries to load file using below code
file.toPath().toRealPath() once above code fails we get warning , not sure why toRealtPath does not work Thought it is able to load using directly resources/jasperreport/subreport1.jasper without usign toRealpath option .
Any suggestion on file path to be used.
