Recently we have added project Wonder framework to our application. It is compiling and running properly on my development system but when I am deploying it to our Solaris server I am getting the following error :
This isn't a problem with wonder exactly, it's a problem with your build system pulling a java-5 built version of wobootstrap.jar from somewhere (usually wotaskd) instead of one built with 1.4 that would have come with 5.2.4. Did you install a newer version of wotaskd or javamonitor on your build system?
Try adjusting your build parameters to use a different location to retrieve a wobootstrap.jar from a WO 5.2.4 application so that it will work with java 1.4 Exception in thread "main" java.lang.UnsupportedClassVersionError: com/webobjects/_bootstrap/WOBootstrap (Unsupported major.minor version 49.0) at java.lang.ClassLoader.defineClass0(Native Method)
