EAP 6.2 java.lang.ClassNotFoundException: com.sun.image.codec.jpeg.JPEGImageEncoder

Hi,

I'm having a problem on EAP 6.2 .  The application in question uses a third party charting tools and runs fine on the developer's Windows machine with EAP 6 (through JBoss Developer Studio). However, when we deploy that application to an EAP 6.2 server on Red Hat Linux, and attempt to create a chart, we receive a "java.lang.ClassNotFoundException: com.sun.image.codec.jpeg.JPEGImageEncoder" error. I've researched the issue online and found a reference to needing a path (path name="com/sun/image/codec/jpeg") in the sun.jdk module.xml. But, we've verified that this path already exists.

Does anybody have any ideas what might be causing the problem? Unfortunately, I do not have the option of changing the charting tool.

Are you sure you're running the Oracle VM?  OpenJDK is the default on RHEL.

if path is in sun.jdk module than it should work.

can you post full stacktrace?

Thank you for your quick response. My server admin tells me that the default OpenJDK is what is installed on the RHEL box. This explains the issue since OpenJDK does not have the com.sun.image.codec.jpeg package.

Thank you for your response. It turns out that the RHEL server is using on OpenJDK instead of an Oracle JDK. OpenJDK does not have this particular package which explains the error message.
