How to resolve Error: Could not find mediaLib accelerator wrapper classes?

[Anuvab Ghosh, modifié il y a 8 années.]

Hi,
I am using liferay 6.2 with jboss server and using jdk1.6.0_45. When I start the jboss server, in server log I have traced an error with an exception, mentioned below.

How to resolve this error?

Please give some suggestion.

Thanks in advance.

That's a jar from Java Advanced Imaging, JAI. It used to be available as a separate download from java.sun.com.

Thanks for the reply.
Do I need to replace it with the existing?
If yes then can you tell me about the location?
Otherwise please provide some details about the solution procedure.

[Tobias Liefke, modifié il y a 8 années.]

You can find the JAI download including installation instructions here:
http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-java-client-419417.html

But if JAI is nor really necessary, you can simply turn this off by setting the system property com.sun.media.jai.disableMediaLib to true.

Thanks for the reply.

Can you told me how to set this?

Will I add this property in portal-ext.properties?

Please explain it.

Thanks in advance

[David H Nebinger, modifié il y a 8 années.]

It's a system property, so you'd have to do it at a system level, i.e. by adding "-Dcom.sun.media.jai.disableMediaLib=true" in setenv.bat/sh for tomcat.

Thank you David.
