ClassNotFoundException for JRDataSource

[roped]

Hi @all,

I made some reports and with JasperReports version 5.0.4 printing / viewing works fine both running in IDE (Eclipse) and running with Java WebStart.
When using 5.5.1 and 5.6.0 it still works in Eclipse but when running with Webstart I get a ClassNotFoundException for JRDataSource (when I import JRException in my JavaClass I get the classNotFoun on JRException).

findJar says that JRDataSource is contained in jasperreports-x.x.x.jar

So I checked the libraries I load in Webstart more than once and I import the same jars both in Eclipse and my Webstart-JNLP-file. But in Eclipse it works, with Webstart it doesn't.
When using jasperreports-5.0.4 everything works fine in both so I don't assume that JRDataSource / JRException moved to another jar meanwhile.

The exception is:

In my jnlp-file I use

    for JR 5.0.4:

        <jar href="jasperreports-5.0.4.jar" />

    for JR 5.5.1:

         <jar href="jasperreports-5.5.1.jar" />

I also tried

        <jar href="jasperreports-5.5.1.jar" />
        <jar href="jasperreports-fonts-5.5.1.jar" />
        <jar href="jasperreports-functions-5.5.1.jar" />
        <jar href="joda-time-2.3.jar" />

    for JR 5.6.0:

        <jar href="jasperreports-5.6.0.jar" />
        <jar href="jasperreports-fonts-5.6.0.jar" />
        <jar href="joda-time-2.3.jar" />

Has anyone an idea what could be the reason and how to fix it?

Thanks a lot in advance,

Roland

Hi,

sorry, till now i didn't find any solution. My application still runs with JasperReports 5.0.4.
JR 5.5.x and JR 6.0.0 both show the same problem. When i change the order of the jars referenced in the jnlp-file, i sometimes get the noClassDefFoundError for JRException. Perhaps that's a hint for searching, but still i didn't find an appropriate order.
