strange solr version error

[Jenny Huang]

Hi,

I need to use solrj to do a full data import from a table in database, and
encountered the solr version error: "java.lang.RuntimeException: Invalid
version (expected 2, but 60) or the data in not in 'javabin' format".  To
figure out what went wrong, I stripped the program to bare bone and let it
run data import for the 'db' in solr tutorial example-DIH
(\solr-4.3.0\example\example-DIH), and experienced the same version error.

I downloaded and run the most recent solr-4.3.0 in window 7, and pulled the
same version of solrj when writing the small solrj program for data import
(see below maven import).

        <dependency>
            <groupId>org.apache.solr</groupId>
            <artifactId>solr-solrj</artifactId>
            <version>4.3.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.solr</groupId>
            <artifactId>solr-core</artifactId>
            <version>4.3.0</version>
        </dependency>


The main part of data import solrj program is very simple, see below.

public class DbDataImportClient {
    public void fullImport(String url) {
        try {
           HttpSolrServer server = new HttpSolrServer(url);
           ModifiableSolrParams params = new ModifiableSolrParams();
           params.set("qt", "/dataimport");
           params.set("command", "full-import");
           server.query(params);
         } catch (Exception e) {
            e.printStackTrace();
          }
    }

    public static void main(String[] args) {
        String url = "http://localhost:8983/solr/#/db";;
        new DbDataImportClient().fullImport(url);
    }
}

I have been going through almost all the pieces of internet search for that
error for two days.  Majority of them are about incompatible versions.  I
don't think it's my case.  I am at my wits end on what went wrong, and
really need help in the problem.


Thanks ahead.
