I checked the same routine in T2.1 beta2, where you do not have to
initiate the GUI first. Instead, the GUI pops up asking for master password.
However, in T2.1 you will get an error:
WARN 2010-01-25 16:40:53,127 (net.sf.taverna.raven.spi.SpiRegistry:85)
- Could not find class net.s
f.taverna.t2.security.credentialmanager.UIMasterPasswordProvider using
loader{net.sf.taverna.t2.tave
rna-workbench.plugins:components-plugin:2.1.0} from 2003979
java.lang.ClassNotFoundException:
net.sf.taverna.t2.security.credentialmanager.UIMasterPasswordProvi
der
Any idea?
