Dear Solr Team,
I am trying to index Word and PDF documents with Solr using SolrJ, but
most of the examples I found on the internet use the SolrServer class
which I guess is deprecated.
The connection to Solr itself is working, because I can add
SolrInputDocuments to the index but it does not work for rich documents
because I get an exception.
public static void main(String[] args) throws IOException,
SolrServerException {
String urlString = "http://localhost:8983/solr/localDocs16";;
HttpSolrClient solr = new
HttpSolrClient.Builder(urlString).build();
//is working
for(int i=0;i<1000;++i) {
SolrInputDocument doc = new SolrInputDocument();
doc.addField("cat", "book");
doc.addField("id", "book-" + i);
doc.addField("name", "The Legend of the Hobbit part " + i);
solr.add(doc);
if(i%100==0) solr.commit(); // periodically flush
}
//is not working
File file = new File("path\\testfile.pdf");
ContentStreamUpdateRequest req = new
ContentStreamUpdateRequest("update/extract");
req.addFile(file, "application/pdf");
req.setParam("literal.id", "doc1");
req.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);
try{
solr.request(req);
}
catch(IOException e){
PrintWriter out = new
PrintWriter("C:\\Users\\mareike\\Desktop\\filename.txt");
e.printStackTrace(out);
out.close();
System.out.println("IO message: " + e.getMessage());
} catch(SolrServerException e){
PrintWriter out = new
PrintWriter("C:\\Users\\mareike\\Desktop\\filename.txt");
e.printStackTrace(out);
out.close();
System.out.println("SolrServer message: " + e.getMessage());
} catch(Exception e){
PrintWriter out = new
PrintWriter("C:\\Users\\mareike\\Desktop\\filename.txt");
e.printStackTrace(out);
out.close();
System.out.println("UnknownException message: " +
e.getMessage());
}finally{
solr.commit();
}
}
I am using Maven (pom.xml attached) and created a JAR file, which I then
tried to execute from the command line, and this is the output I get:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for
further details.
SLF4J: Failed to load class "org.slf4j.impl.StaticMDCBinder".
SLF4J: Defaulting to no-operation MDCAdapter implementation.
SLF4J: See http://www.slf4j.org/codes.html#no_static_mdc_binder for
further details.
message: *UnknownException message: Error from server at
http://localhost:8983/solr/localDocs17: Bad contentType for search
handler :application/pdf request={wt=javabin&version=2}*
I hope you may be able to help me with this. I also posted this issue on
Github
