{noformat}

the method

{noformat}
public static ExternalResourceDescription createExternalResourceDescription(Class<? extends
Resource> aInterface, Object... aParams)
{noformat}
does not accept non-string parameters.

Example:
The following works:

{noformat}
ExternalResourceDescription geographicalResourceDescription = ExternalResourceFactory.createExternalResourceDescription(
					GeographicalResourceImplementation.class,
GeographicalResource.MAX_LENGTH_PARAMETER, String.valueOf(5),
);
{noformat}

Resource:
{noformat}
@ConfigurationParameter(name = MAX_LENGTH_PARAMETER)
private String maxLengthString;
{noformat}

The following fails:
Caller:

{noformat}
ExternalResourceDescription geographicalResourceDescription = ExternalResourceFactory.createExternalResourceDescription(
					GeographicalResourceImplementation.class,
GeographicalResource.MAX_LENGTH_PARAMETER, 5,
);
{noformat}

Resource:

{noformat}
@ConfigurationParameter(name = MAX_LENGTH_PARAMETER)
private int maxLength;
{noformat}


The exception is:
