When trying to submit and order using this code

engine.submitOrder("jh", selectedInstrument, IEngine.OrderCommand.BUY, 0.1, 0, 0, askPrice-SL*instrument.getPipValue(), askPrice+TP*instrument.getPipValue());

I get this error message

23:51:21 Strategy tester: java.lang.SecurityException: class "com.dukascopy.api.IOrder$State" does not match trust level of other classes in the same package @ jforex.FileRead.onTick(FileRead.java:208)

Sorted it out, in case any one is wondering it had to do with the java security level settings on the computer, after changing them I had to restart which I wasn't doing.

I have the same problem but I could not figure out where to change those security settings.
I have the following:

public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
        // Check instrument
        if(instrument != Instrument.EURUSD)
            return;
        // Check if previous close is higher or not
        IBar prevBar = history.getBar(Instrument.EURUSD, Period.ONE_MIN, OfferSide.BID, 1);
        if(bidBar.getClose()<prevBar.getClose()){
            console.getOut().println("Bear");
        }
        else{
            console.getOut().println("Bull");
        }
    }

When this method gets called, the following error is printed in the Messages tab:

16:43:40 java.lang.SecurityException: class "com.dukascopy.api.impl.j" does not match trust level of other classes in the same package @ MyInitialStrategy.onBar(MyInitialStrategy.java:45)

Line 45 is mapped here to Line 6:

IBar prevBar = history.getBar(Instrument.EURUSD, Period.ONE_MIN, OfferSide.BID, 1);

Why is this message raised and what can I do about it?
Please help.

We could not replicate the issue.
Could you please provide the Java security settings that fixed the problem?

Ok, for now I have found that it is no good idea to have the strategy file saved in the eclipse workspace.
If you copy it to another empty location where it does not interfere with other project files, then the problem may disappear.
At least this solved my problem for now.
I think it has something to do with mixed mode security issues, see here.
