Problem with groovy-all-1.7.5.jar

[xujin_helen]

Hi,

I am using Eclipse Helios with Jaspersoft Studio 1.1.1.

Basically, when I preview report, I can't include groovy jar; however, when I use Java to generate pdf, I need that lib. This is inconvenient to include and exclude during different time within the same project.

When I Preview Report.jrxml, it will throw below error when I INCLUDE groovy-all-1.7.5.jar

java.lang.LinkageError: loader constraint violation: loader (instance of java/net/URLClassLoader) previously initiated loading for a different type with name "groovy/lang/MetaClass"

Hi Jin,
could you please write down the following additional information:

• what are the steps you take to add jars to build path
• which are the jars you have in your build path once you've performed these steps
• is the project containing the report and PDFGenerator class, a JasperReport project or do you have added the JasperReport nature to an existing one?
• could attacch .project and .classpath file 

I've tried to reproduce your problem using your Java file and JRXML file.
However I was able to run both the preview and generate the pdf file via java code (see attached screenshot). 

Best regards,
Massimo.

Hi Massimo,

what are the steps you take to add jars to build path

In eclipse, right click the project => select Properties => select Java Build Path from left pane => click Add External JARs button.

which are the jars you have in your build path once you've performed these steps

Below are the libraries I currently have. All are from Jaspersoft standalone installation. At the beginning, I only add jasperreports-4.6.0.jar. Based on every compile error, I add below rest libraries. I am not sure whether Jasper support maven repository.

commons-beanutils-1.8.0.jar
commons-collections-2.1.1.jar
commons-digester-2.1.jar
commons-logging-1.1.1.jar
iText-2.1.7.jar
jasperreports-4.6.0.jar

is the project containing the report and PDFGenerator class, a JasperReport project or do you have added the JasperReport nature to an existing one?

Yes, one project contains both reports jrxml and java.

could attacch .project and .classpath file 

Please see attached.

Thanks,

Jin

Hi Jin,
I tried to extend the tests and I was able to reproduce the problems in JSS 1.1.1, but not in JSS 1.1.2.
I'm quite confident the error you got has been fixed with the latest release 1.1.2. 
Some modifications and improvements were introduced, also related to ClassLoading (JavaProjectClassLoader class was modified).

Please try to upgrade to latest 1.1.2 and verify if the problem disappears.

Best Regards,
Massimo

Hi Massimo,

You are right. After installing 1.1.2, this problem is gone. Thanks for the tip.

Right now I have another problem with barcode. I will create a new ticket.

Thanks,

Jin

Where can I download JSS 1.1.2?

[Massimo Rabbi]

Hi,
for the stand-alone version you can use the Sourceforge project page where all files are mantained:

http://sourceforge.net/projects/jasperstudio/files/JaspersoftStudio-1.1.2/

For the plug-in version you can use the standard update site

http://jasperstudio.sourceforge.net/updates/

Best regards,
Massimo.
