I can compile and successfully use an indicator (sma over rsi from forum) but when want it to use in 'standard mode' by selected the indicator from 'my indicators' I get the message "cannot instantiate indicator".
This is all done within a live account.
What I would like to know:
- Is there a way to get more information about this error? E.g. a stacktrace?
- In which situations do I get this error? What did I do wrong?
- Is there a way to store (in the worspace.xml?) the selection of 'my indicators' so that I don't have to select them everytime I open the session?

Many thanks in advance!

Stack trace you can find in java console.

Yes, click a right mouse button on the "Workspace" label and choose save. One more option is to turn on workspace auto saving. Open Tools-> Preferences->Workspace. Click on check box "Perform Workspace Auto saving"

Many thanks for the prompt reply!

It's not clear for me, what "Stack trace you can find in java console. " means. When I try to use the indicator at an open chart in 'standard mode' there is no 'java console' - or am I wrong? The error message is displayed on the message window at the bottom of jforex. How can I get to the java console in 'standard mode'?
By the way, I can use the indicator in jforex mode, i.e. in the development environment.

Thanks!

The custom indicator "SMA over RSI" (from the forum) is selected from my "My Indicators" directory. The same error comes up when I delete the package "jforex" from the code. - the classNotFoundException remains.

Please, verify that you have a compiled version(jfx file) of your indicator that you are using.
