I’m running some graphs from java.

How can I add or override the values in the graph’s parameters (workspace.prm or internal parameters)?

Is the answer to call GraphRuntimeContext.setAdditionalProperties()?

Thanks.

Hello,  
method _org.jetel.graph.runtime.GraphRuntimeContext.setAdditionalProperties(Properties)_ clears all parameters and sets the new ones, method _org.jetel.graph.runtime.GraphRuntimeContext.addAdditionalProperties(Properties)_ adds new parameters to the existing ones (if the name of a new parameter is the same as the existing one, it will be replaced by the new value).
