Could you provide a stack trace for the NullPointerException? I was able to run the example without issue just now.

Also, please indicate which version of the AdWords API you are using (v201406 or v201409).

Thanks

Hi Josh,

Exception in thread "main" java.lang.NullPointerException
at
adwords.axis.v201409.optimization.EstimateKeywordTraffic.runExample(EstimateKeywordTraffic.java:144)
at
adwords.axis.v201409.optimization.EstimateKeywordTraffic.main(EstimateKeywordTraffic.java:70)

this is what I get every time that I try to compile the
EstimateKeywordTraffic example, every other one works just fine in my
machine.

Thanks for your reply,

Best

Jorge

Thanks - a NullPointerException at that point means that the keyword you were searching for resulted in a KeywordEstimate with null attributes.

// Find the mean of the min and max values.
double meanAverageCpc =
    (keywordEstimate.getMin().getAverageCpc().getMicroAmount() + keywordEstimate.getMax()
        .getAverageCpc().getMicroAmount()) / 2.0;

Which keywords did you include in your request (starting at line 83)? I haven't been able to produce a request that results in null attributes on a KeywordEstimate.

Hi Josh,

I haven't change the code, the keywords are exactly the ones from the
example.
I also have this warning message
log4j:WARN No appenders could be found for logger
(org.apache.commons.configuration.PropertiesConfiguration).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for
more info.

and since the issue is that I'm receiving a null answer from the API could
that be the issue?

Let's continue the discussion on your forum post, as it looks like this is a problem with your setup, not the Java library.
