Subject RE: Continuous stream of errors from agents (using ManifoldCF 2.4)

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

Subject: Continuous stream of errors from agents (using ManifoldCF 2.4)

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.http.conn.ssl.SSLConnectionSocketFactory.<init>(
       at org.apache.manifoldcf.agents.output.solr.HttpPoster.<init>(
        at org.apache.manifoldcf.agents.output.solr.SolrConnector.getSession(
        at org.apache.manifoldcf.agents.output.solr.SolrConnector.getPipelineDescription(
        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!
