I have this directory structure.Tomcat Root webapps reports -->images --> company_logo.jpg -->reports -->sample.jasper -->WEB-INF -->classesAnd I tried doing this thinking that this is relative to my reports context root<image> <reportElement x="0" y="0" width="104" height="40"/> <imageExpression class="java.lang.String"> <![CDATA["images/company_logo.jpg"]]> </imageExpression></image>..and this also<image> <reportElement x="0" y="0" width="104" height="40"/> <imageExpression class="java.lang.String"> <![CDATA["/images/company_logo.jpg"]]> </imageExpression></image>but it always says there was an error loading bytes from location JRLoader.I tried doing this and it works, but I am a bit confused why my first two attempt doesn't.Is this really how you embed images in JasperReports? Do you need to supply the whole path? I am thinking that there should be a page relativesomething.<image> <reportElement x="0" y="0" width="104" height="40"/> <imageExpression class="java.lang.String"> <![CDATA["http://localhost:8080/reports/images/company_logo.jpg"]]> </imageExpression></image>I am a bit puzzled about the correct way. 解决方案 <![CDATA["../images/company_logo.jpg"]]> should do the trick. The path is relative to your .jasper file. 这篇关于Jasper Reports中的图像表达式URL的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云! 06-18 22:46
