Thanks Konrad,


Good catch!  I think it’s my startup scripts that need to be looked at.


I’ll double check, and let the list know if it works.

Hi Adrian,


it looks like a class it not found. Can you check your JARs for current http components (available from httpcore-4.4.4.jar does contain the missing class.


You may also want to check the order of the JARs in the classpath when starting ManifoldCF.


Hope that helps

Hi List,


I’ve just started experimenting with using ManifoldCF 2.4 in our deployments and I’m coming across a problem.


None of the jobs are progressing at all, past deciding that they have a single document to process, and my logs are being flooded with the following:


FATAL 2016-05-06 15:09:38,350 (Worker thread '0') - Error tossed: org/apache/http/util/Args

java.lang.NoClassDefFoundError: org/apache/http/util/Args

        at org.apache.http.conn.ssl.SSLConnectionSocketFactory.<init>(

        at org.apache.manifoldcf.agents.incrementalingest.IncrementalIngester.getOutputDescription(

        at org.apache.manifoldcf.crawler.system.PipelineSpecification.<init>(



Any ideas where to look?  The scripts I’m using for deployment are exactly the same as I’m using with v2.3.  I’m assuming I’m missing a step somewhere…


Thanks for any help received!
