Getting a wierd Class Not Found Exception: SolrParams
Hi All
I have been getting this wierd error since yday evening, whose cause I am
not able to figure out.
I made a webinterface to read and display Solr Results, which is a servlet
that calls Solr Servlet.
I am
I give the query to Solr, using:
MultiMapSolrParams solrparamsmini =
SolrRequestParsers.parseQueryString(queryrequest.toString());
-where queryrequest contains all the ingredients of a Solr query.
Eg: StringBuffer queryrequest = new StringBuffer();
queryrequest.append("&q=" + query);
queryrequest.append("&start=0&rows=30&hl=true&hl.fl=text&hl.frag=500&defType=dismax");
queryrequest.append("&bq="+Field1+":["+frompercent+"%20TO%20"+topercent+"]");
It compiles and builds without errors, but I get this error
"java.lang.ClassNotFoundException:
org.apache.solr.common.params.SolrParams", when I run the app.
But, I dont use SolrParams class anywhere in my code!
Here is the stack trace:

Hi Eric
Yes, it was a classpath issue.

Re: Getting a wierd Class Not Found Exception: SolrParams

Well, MultiMapSolrParams is a subclass of SolrParams, so you actually
do use it in your code <G>....
But this looks like a classpath problem. You say your code compiles,
but do you make all the jars you path to during compilation available
to your servlet? And/or do you have any old jar files in your classpath?
