java.lang.NoSuchMethodError: org.apache.commons.httpclient.HttpConnectionManager.getParams()Lorg/apache/commons/httpclient/params/HttpConnectionManagerParams;

[Sulman <su...@gmail.com>]

Hi, 

I am developing a search application. When I try to create an instance of
CommonsHttpSolrServer I  get an Error: java.lang.NoSuchMethodError:
org.apache.commons.httpclient.HttpConnectionManager.getParams()Lorg/apache/commons/httpclient/params/HttpConnectionManagerParams;


Strangely i dont get this error when i execute this code from command line.
This error only occurs when i access it from a web application. Secondly,
this same method works fine with another web application. Both web
applications are deployed on tomcat 6. One application works fine and the
other one crashes. I have read on forums to check for the versions of
commons-httpclient and solrj. I have attached my pom entries below as well.
They seem fine (as the same code works fine from command line and from web
application for first application) . Any suggestions?

-----
Code
------
String serverUrl = "http://localhost:8080/solr-scots/";
CommonsHttpSolrServer server = new CommonsHttpSolrServer(serverUrl);


--------
pom.xml
----------

       <dependency>
		<groupId>commons-httpclient</groupId>
		<artifactId>commons-httpclient</artifactId>
		<version>3.1</version>

    	<version>1.3.0</version>

...if you only get this problem in some enviornments, then i suspect there 
is something wrong with those environments (and clearly not with the 
code).    I would start by checking every jar in all of your environments 
and making sure you don't have multiple copies of hte same jar (in 
different versions) mistakenly installed.
