[Hyperic-hq-discuss] UnsupportedClassVersionError when testing device_iostat.pl plugin

[Nathaniel B. <nb...@ep...>]

Hi-

I am trying to implement the device_iostat.pl plugin and am unable to get it to return results. I'm pretty sure I have the plugin bits in the write places on the server:

agent:
/home/hyperic/hyperic-hq-agent-3.0.1/pdk/scripts/device_iostat.pl

Server:
/u05/hyperic/server-3.0.1/hq-engine/server/default/deploy/hq.ear/hq-plugins/io-device-plugin.xml

When I run the following test, I get an error message that references 'Exception in thread "main" java.lang.UnsupportedClassVersionError: org/hyperic/hq/product/util/PluginMain (Unsupported major.minor version 48.0)'. Here is the output from these java test:

$ java -jar hq-product.jar -Dplugins.include=io-device -Ddevice=cciss/c0d1p1 -Dlog=debug
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/hyperic/hq/product/util/PluginMain (Unsupported major.minor version 48.0)

Have I missed a configuration step along the way, or do I need to update java?

Thanks...
