It tries to find it automatically if it's not set (and in any case, since the Jar will be downloaded via Java WebStart, you don't know where it is). However, I recall that there was a bug with the name of the osgi.jar in 3.2.1; get rid of the R32x_ from the name (i.e. org.eclipse.osgi_3.2.1.R32x_v2345 -> org.eclipse.osgi_3.2.1-v2345). 解决的方法就是把org.eclipse.osgi_3.2.1.R32x_v2345 改名成org.eclipse.osgi_3.2.1-v2345,同时把jnlp中引用的文件名也改过来。这是eclipse的一个bug
