Error in executing Solr query using JNI in C using java class

[piyush gururani]

I have a java class which executes Solr query and prints the output , which
is working perfectly well .
I am using EmbeddedSolrServer , snippet is below :


        String solrDir =
"/Users/TheRoot/Downloads/solr-4.7.0/example/solr/";
        CoreContainer container = new CoreContainer(solrDir);
        container.load();
        EmbeddedSolrServer server = new EmbeddedSolrServer(container,
"collection1");
        ModifiableSolrParams solrParams = new ModifiableSolrParams();
        solrParams.add(CommonParams.Q, "*:*");
        QueryResponse queryResponse = null;
        try {
            queryResponse = server.query(solrParams);
        } catch (SolrServerException e) {
            e.printStackTrace();
        }
        for (SolrDocument document : queryResponse.getResults()) {
            System.out.println(document.getFieldValueMap().toString());
        }
        server.shutdown();
        container.shutdown();


But when I try to access main from my C code , it throws error saying :


*Invalid memory access of location 0x0 rip=0x109fbdfac*

When I comment out

        try {
            queryResponse = server.query(solrParams);
        } catch (SolrServerException e) {
            e.printStackTrace();
        }
        for (SolrDocument document : queryResponse.getResults()) {
            System.out.println(document.getFieldValueMap().toString());
        }


error is not thrown .
My C code snippt is below :


     EmbeddedSolrExample_Class = (*env)->FindClass(env,
"EmbeddedSolrExample");
     main_method = (*env)->GetStaticMethodID(env,
EmbeddedSolrExample_Class, "main", "([Ljava/lang/String;)V");
      (*env)->CallStaticVoidMethod(env, EmbeddedSolrExample_Class,
main_method, NULL);


*Although I am able to access and get output from other functions from the
java class . *
