I agree with Dina, I think the cagrid-activity does not directly
interact with the password provider. It only instantiate a credential
manager.

Hi Dina,
Looks like caGrid activity is trying to pop-up a dialog and you are
running in "the server mode" i.e. in a headless environment.
Yes, I am running it from the command-prompt (server mode). But isn't
adding my own SPI implementation (MyMasterPasswordProvider.java) the
way to override the pop-up dialogs? When I am running it in the Server
mode, my project has a master password provider:
public class MyMasterPasswordProvider implements CredentialProviderSPI {
....(you can see the implementation below from my previous email).
This is how I got it working in 2.1.1 (and 2.1.0). But it looks like
the CredentialManager is not getting my MyMasterPasswordProvider when
it is looking for a Master Password??
Is there anything I need to do differently in 2.1.2 to provide my own
Master password?
Thanks,

Look at the line
at
net.sf.taverna.cagrid.activity.CaGridActivity.initializeSecurity(CaGridActivity.java:752)
Check first if you are running headlessly and then make sure there
are no GUI pop-ups - I think that remained from the caGrid activity
when it was only ran in a Workbench. If you are running headlessly
you have to provide passwords some other way and not ask user for
them. I think it is asking for a Java truststore password when you
get that error but I do not have the latest code to check it.
Cheers,
Alex

Hi,
I am upgrading our TavernaExecutor to T2.1.2 jars and it looks like
the changes in the CredentialProviderSPI interface is giving some
errors. I have added my own master password provider with higher
priority but after a quick debug, it looks like
"MyMasterPasswordProvider" isn't getting picked!!
List<CredentialProviderSPI> masterPasswordProviders =
findMasterPasswordProviders();
the list above in CredentialManager.java doesn't have
mymasterpasswordprovider that I have added in my project. It worked
fine in the previous versions (2.1.1 and 2.1-beta2).
I have checked in the Executor project at svn for you to take a
quick look: https://svn.ci.uchicago.edu/svn/caBIG/TavernaExecutor
MyMasterPasswordProvider.java looks as pasted below.
public class MyMasterPasswordProvider implements CredentialProviderSPI {
public boolean canHandleTrustConfirmation(X509Certificate[] arg0) {
return false;
}
public boolean canProvideJavaTruststorePassword() {
return false;
}
public boolean canProvideMasterPassword() {
return true;
}
public boolean canProvideUsernamePassword(URI arg0) {
return false;
}
public String getJavaTruststorePassword() {
return null;
}
public String getMasterPassword(boolean arg0) {
return "somePass";
}
public int getProviderPriority() {
return 500;
}
public UsernamePassword getUsernamePassword(URI arg0, String arg1) {
return null;
}
public TrustConfirmation shouldTrust(X509Certificate[] arg0) {
return null;
}
}
I get the following error when I try to run any workflow that has
secure workflows and requires cagrid-activity and credential-manager:
