When i use

JasperRunManager.runReportToPdf(String ,Map , Connection ) in the Servlet,it return null,but i think the parameters are all right. The first para String is the absolute filepath and the Map and Connection are all right.

But when i use this method in the application,it throw exception as below:

java.io.StreamCorruptedException: invalid stream header

 

Could you give me any mind?

Thank you

JasperRunManager.runReportToPdf(String ,Map,Connection),this method's first parameter is the xml file absolute path?

It is useful when i use this method JasperRunManager.runReportToPdf(JasperReport,Map,Connection),but at run time,it throw such exceptions:

C:JBuilder8samplesWelcomeTomcatjq_good_detail.java:4: package dori.jasper.engine does not exist

 

import dori.jasper.engine.*;

 

what's the problem about it? it is the Web server Tomcat's problem?

 

Thank you

I refer to the Web App of the jasper example and it set a system property named "jasper.reports.compile.class.path",after i set it as the example,then it is OK. Web server find the classpath from some certain path. So i dont understand it.Why i need this property?
