Get Java 7.

ThCxProToTypE · August 2, 2012

Use this link for the correct version of Java: http://javadl.sun.com/webapps/download/AutoDL?BundleId=65693

I have had this problem before.

Stevews602 · August 3, 2012

Sorry I am on a Mac running OSX 10.6.8

ThCxProToTypE · August 3, 2012

Mac uses its own version of java so I am not exactly sure how you are going to be able to resolve this.

Stevews602 · August 4, 2012

Does anyone else have a clue as to why this works just great with Minecraft server but not Tekkit server?

Stevews602 · August 5, 2012

As I cannot load Java 7, I deleted the advanced computer .zip from the mods folder and the server is loading correctly now. However I still cannot connect either locally or via the internet. I am not getting a end of stream error.
