Using parameters of PearSpecifier for configuring wrapped analysis engine description

The PearSpecifier provides functionality for setting parameters, which could be used for configuring the wrapped analysis engine description.

I want to configure a PEAR dynamically. (I install the pear and want to produce the analysis engine with different parameters than in the xml).
Is this possible? Can I use the additionalParameters? I have seen that the PearSpecifier has an instance variable for parameters, but no one is using (calling) it.

I want to produce the analysisEngine with: UIMAFramework.produceAnalysisEngine(resourceSpecifer, resourceManager, params);

In this specifier there should be one or more pearSpecifiers that should be configured.

I have overridden the PearAnalysisEngineWrapper and built a loop that configures the following specifier over the configurationParameterSettings. It takes the parameters from the pear specifiers.

line 257-258
// Parse the resource specifier
ResourceSpecifier specifier = UIMAFramework.getXMLParser().parseResourceSpecifier(in);

==> added code
AnalysisEngineDescription analysisEngineDescription = (AnalysisEngineDescription) specifier;
AnalysisEngineMetaData analysisEngineMetaData = analysisEngineDescription.getAnalysisEngineMetaData();
ConfigurationParameterSettings configurationParameterSettings = analysisEngineMetaData.getConfigurationParameterSettings();
for (Parameter parameter : Arrays.asList(pearSpec.getParameters()))

Unknown macro: { configurationParameterSettings.setParameterValue(parameter.getName(), parameter.getValue()); }
