Solrj problem
Hello, I'm struggling to retreive some data from my localhost Solr from an
Android Application. but i'm still having the same error.
/05-06 18:22:09.036: E/AndroidRuntime(1628): java.lang.NoSuchMethodError:
org.apache.http.conn.scheme.Scheme.<init>
05-06 18:22:09.036: E/AndroidRuntime(1628): at

org.apache.http.impl.client.AbstractHttpClient.getConnectionManager(AbstractHttpClient.java:221)/
I'm using these Jars :
- Commons-io-2.1.jar
- httpclient-4.3.1.jar
- httpcore-4.3.jar
- jcl-over-slf4j-1.6.6.jar
- jul-to-slf4j-1.6.6.jar
- log4j-1.2.16.jar
- slf4j-api-1.6.6.jar
- slf4j-log4j12-1.6.6.jar
- solr-solrj-4.8.0jar
and this is the code I wrote :
/package com.example.secondapp;
import java.net.MalformedURLException;
import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.SolrServer;
import org.apache.solr.client.solrj.SolrServerException;

import org.apache.solr.client.solrj.response.QueryResponse;
import org.apache.solr.common.SolrDocumentList;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends Activity {
Button btn1;
EditText etxt1;
public void RunIt() throws MalformedURLException, SolrServerException
{
String urlString = "http://localhost:8983/solr/collection1";
SolrServer solr = new HttpSolrServer(urlString);
SolrQuery parameters = new SolrQuery();
parameters.set("qt", "/select");
parameters.set("q", "mem");
QueryResponse response = solr.query(parameters);
SolrDocumentList list = response.getResults();
// for (int i = 0; i < list.size(); ++i) {
// etxt1.setText((CharSequence) list.get(i));
//}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn1=(Button)findViewById(R.id.button1);
etxt1=(EditText)findViewById(R.id.editText1);
btn1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
etxt1.setText("a fin111");
try {
RunIt();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SolrServerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
}/

SOLVED,
I didn't use SOLRJ, just normal Httpclient methodes + asynktask
HttpClient client = new DefaultHttpClient();
URI uri = new URI(params[0]);
HttpGet Gett = new HttpGet(uri);
HttpResponse response= client.execute(Gett);
InputStream stream = response.getEntity().getContent();
reader = new BufferedReader(new InputStreamReader(stream));
StringBuffer buffer = new StringBuffer("");
String line="";
String newline=System.getProperty("line.separator");
while ((line= reader.readLine())!=null)
{
buffer.append(line + newline);
}
reader.close();
data= buffer.toString();
return data;

I committed this patch to Solr. It upgraded the HttpClient jars used in
Solr to 4.3.1.
This change reached users with the 4.7.0 release. No code changes were
required -- Solr and SolrJ were already compatible with the newer
HttpClient version. It should also work with HttpClient 4.2.x, as well
as the newest release.
Thanks,
Shawn

Hello Shawn,
according to this : https://issues.apache.org/jira/browse/SOLR-5590
I understand that solrj is still depends on the old httpclient shipped with
android tools, and this is my problem too. KARL has made an patch, could you
please explain what that patch for,
how can I use it in to solve my problem?

The class/method that it says it can't find is in httpclient-4.3.1.jar.
I think there are two possibilities here: 1) This jar is not in the
classpath at runtime. 2) You have a different version of httpclient in
your classpath that does not a method with a precise match on the signature.
Thanks,
Shawn
