org.apache.*.*.... class not found exception in Internet Explorer
Hi,
I'm trying to query solr indexer thru a web page and trying to display the
result. I've the following class to query solr [I'm using the query(string)
method],
import org.apache.solr.common.SolrDocumentList;

import java.util.Map;
import java.util.Iterator;

try

}
catch(Exception e)
{
e.printStackTrace();
}
SolrQuery query = new SolrQuery();
query.setQuery(q);
query.setQueryType(dismax);
query.setIncludeScore(true);
try
{
QueryResponse qr = server.query(query);
SolrDocumentList sdl = qr.getResults();
//System.out.println(Found: + sdl.getNumFound());
//System.out.println(Start: + sdl.getStart());
//System.out.println(Max Score: + sdl.getMaxScore());
//System.out.println();
//System.out.println(Result doc : + sdl);
return sdl.toString();
}
catch (SolrServerException e)
{
e.printStackTrace();
return null;
}
}
}
and the following to pass the queries to solr, get results and display it on
the browser,
import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Font;
public class ControlJava extends Applet {
Font f = new Font(TimesRoman, Font.BOLD, 20);
String Message;
public void init() {

public void SetMessage(String MsgText) {

Message = solr.query(MsgText);
repaint();
}
public void paint(Graphics g) {
g.setFont(f);
g.drawString(Message, 15, 50);
}
}
and finally the html page is this,

When I'm trying to access this page and putting the query in the box that
this html shows, the browser [IE] gives some error and after checking I
found that the error is some class not found exception, its not able to find
the org.apache.*.* classes and hence giving errors. Now instead of
calling that I wrote a simpe class not using any apache.solr classes and
called the method therein [just returns a string] and it worked fine. I
added both both the classes [.class files] given above to the same location
where this web page resides.
The problem is that browser is not able to find those org.apache.*** classes
and creating the mess. Can anyone help this newbie fixing the problem.
Thanks a lot.
Do let me know if some information is missing/want some extra information on
this issue.

How to iterate the solrdocumentlist result
Hi All, I'm able to get the whole result bundle by using the following method, QueryResponse qr = server.query(query); SolrDocumentList sdl = qr.getResults(); but I'm not able to iterate over the results. I converted this to string and displayed that and that is a full result bundle, I think its in XML. Actually I want to display the result in a browser and each one separately, I mean not as a bundle. There must be some standard methods for this, right ? Can some one give me some pointers in this regard... I'm trying to integrate the java method calls withing html code itself[ the solr server is on my box, and I want to do the testing on my box, so I want to access the indexer from my local box's browser only]. Any good ideas on this? Thanks, Ahmed.
Addition of new field to Solr schema.xml not getting reflected properly
Hi All, I'm trying to add a new field to Solr, so I stopped the tomcat[I'm working on Windows] using the Configure Tomcat menu of Tomcat, then added the following field field name=pageContent type=string indexed=true stored=true/ After restarting Tomcat, I couldn't see the changes, so I did the restart couple of times, and then the schema showed me the changes. Now I tried to change the type to text from the current string. I did that and restarted tomcat many times but the changes are still not getting reflected. I've used Solr1.2 earlier on linux, and every time I just had to touch the web.xml in webapp directory thereby forcing tomcat to restart itself for changes in schema.xml to take effect, but in windows I'm not able to figure out whats the issue. Is there anything wrong, I'm I supposed to restart tomcat in some other way instead of using the Configure tomcat menu. Has anyone faced similar issues with solr1.3 on windows? Any suggestion would be appreciated. Thanks, Ahmed.
Re: Addition of new field to Solr schema.xml not getting reflected properly
I added some new documents, and for these docs I can use the new field, right? Though to reflect the changes for all docs I need to delete the old index and build a new one. As I mentioned earlier after a couple of restarts its worked. Still don't know whats the issue. :-) Thanks, Ahmed.

Problem adding unicoded docs to Solr through SolrJ
Hi All,
I'm trying to automate the process of posting xml s to Solr using Solrj.
Essentially I'm extracting the text from a given Url, then creating a
solrDoc and posting the same using the following function,
public void postToSolrUsingSolrj(String rawText, String pageId) {
String url = http://localhost:8983/solr;;
CommonsHttpSolrServer server;
try {
// Get connection to Solr server
server = new CommonsHttpSolrServer(url);
// Set XMLResponseParser : Reqd for older version of Solr 1.3
server.setParser(new XMLResponseParser());
server.setSoTimeout(1000); // socket read timeout
server.setConnectionTimeout(100);
server.setDefaultMaxConnectionsPerHost(100);
server.setMaxTotalConnections(100);
server.setFollowRedirects(false); // defaults to false
// allowCompression defaults to false.
// Server side must support gzip or deflate for this to have
any effect.
server.setAllowCompression(true);
server.setMaxRetries(1); // defaults to 0. 1 not
recommended.
// WARNING : this will delete all pre-existing Solr index
//server.deleteByQuery( *:* );// delete everything!
SolrInputDocument doc = new SolrInputDocument();
doc.addField(id, pageId );
doc.addField(features, rawText );
// Add the docs to Solr Server
server.add(doc);
// Do commit the changes
server.commit();
}catch (Exception e) {}
}
In the above the param rawText is just the html stripped off of all its
tags, js, css etc and pageId is the Url for that page. When I'm using this
for English pages its working perfectly fine but the problem comes up when
I'm trying to index some non-english pages. For them, say pages in tamil,
the encoding Unicode/Utf-8 seems to create some problem, because after
indexing some non-english pages when I'm trying to search those from solr
admin search interface, it gives the result but the content is not showing
in that language i.e tamil rather it just displays just some characters, i
think in unicode. The same thing worked fine for pages in English.
Now what I did is just extracted the raw text from that html page and
manually created an xml page like this
?xml version=1.0 encoding=UTF-8?
add
doc
field name=idUTF2TEST/field
field name=nameTest with some UTF-8 encoded characters/field
field name=features*some tamil unicode text here*/field
/doc
/add
and posted this from command line using the post.jar file. Now searching
gives me the result but unlike last time browser shows the indexed text in
tamil itself and not the raw unicode. So this clearly shows that the string
that I'm using to create the solrDoc seems to have some encoding issues,
right? Or something else? I tried doing something like this also,
// Encode in Unicode UTF-8
utfEncodedText = new String(rawText.getBytes(UTF-8));
but even this didn't help eighter.
Its seems some silly problem some where, which I'm not able to catch. :-)
I appreciate if some one can point me the bug...
Thanks,
Ahmed.
Re: How to post in-memory[not residing on local disks] Xml files to Solr server for indexing?

How to post in-memory[not residing on local disks] Xml files to Solr server for indexing?
Hi All, I'm trying to post some files to Solr server. I've done this using the post.jar files for posting xml files residing on my local disk[I tried posting all those xml files from example directory]. Now I'm trying to generate xml files on the fly, with required text to be indexed included therein though, and want to post these files to solr. As per the examples we've used SimplePostTool for posting locally resinding files but can some one give me direction on indexing in-memory xml files[files generated on the fly]. Actually I want to automate this process in a loop, so that I'll extract some information and put that to xml file and push it off to Solr for indexing. Thanks in appreciation. --Ahmed.

How to indexing non-english html text in unicode with Solr?
Hi All, I'm trying to index some regional/non-eng html pages with Solr. I thought of indexing the corresponding unicode text for that page as Solr supports Unicode indexing, right? But I'm not able to extract Xml from the html page, because for posting to Solr we require Xml. Can anyone tell me any good method of extracting Xml from html or just let me know how to index non-english html pages with Solr that will enable me searching with unicode queries (for corresponding regional query). Thanks in advance. --Ahmed.
