Hello

I experienced the same issue that you but I fixed it replacing the POI 3.17 version with 3.16 version files. These files are located at:
/opt/lincebi/tomcat/webapps/lincebi/WEB-INF/lib

I downloaded 3.16 files from MVN Repository to this location.
Then renamed 3.17 files adding “_original” to the filename.

The folder looked like this:

-rwxrwxr-- 1 lincebi lincebi 2679259 feb 25 13:23 poi-3.16.jar
-rwxrwxr-- 1 lincebi lincebi 2701171 oct 19 16:33 poi-3.17.jar_original
-rwxrwxr-- 1 lincebi lincebi 1433719 feb 25 13:23 poi-ooxml-3.16.jar
-rwxrwxr-- 1 lincebi lincebi 1479023 oct 19 16:33 poi-ooxml-3.17.jar_original
-rwxrwxr-- 1 lincebi lincebi 5871746 feb 25 13:23 poi-ooxml-schemas-3.16.jar
-rwxrwxr-- 1 lincebi lincebi 5924600 oct 19 16:33 poi-ooxml-schemas-3.17.jar_original
-rwxrwxr-- 1 lincebi lincebi 1384931 feb 25 13:23 poi-scratchpad-3.16.jar
-rwxrwxr-- 1 lincebi lincebi 1390360 oct 19 16:33 poi-scratchpad-3.17.jar_original

In the end I restarted LinceBI.

Excel export error was solved but PDF export error was not.

Regards.

As I said before, the problem is not fixed form PDF files.

In log I can see:

ERROR [Pivot4JExceptionHandler] Unhandled exception has occurred
org.apache.myfaces.view.facelets.el.ContextAwareELException: javax.el.ELException: java.lang.ClassCastException: org.apache.xmlgraphics.image.loader.impl.PreloaderRawPNG cannot be cast to org.apache.xmlgraphics.image.loader.spi.ImagePreloader

I’ve googled and found this: Images are not displayed in PDF generated by apache fop

To fix the issue it’s recommended to modify Maven’s configuration here. Any help?

Thanks in advance.
