HTTP 500 error when invoking a REST client in Solr Analyzer
Hi All,
I am working on a custom analyzer in Solr to post content to Apache Stanbol
for enhancement during indexing. To post content to Stanbol, inside my
custom analyzer's incrementToken() method I have written below code using
Jersey client API sample [1];
public boolean incrementToken() throws IOException {
if (!input.incrementToken()) {
return false;
}
char[] buffer = charTermAttr.buffer();
String content = new String(buffer);
Client client = Client.create();
WebResource webResource = client.resource("http://localhost:8080/enhancer");
ClientResponse response = webResource.type("text/plain").accept(new
MediaType("application", "rdf+xml")).post(ClientResponse.class, content);
int status = response.getStatus();
if (status != 200 && status != 201 && status != 202) {
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatus());
}
String output = response.getEntity(String.class);
System.out.println(output);
charTermAttr.setEmpty();
char[] newBuffer = output.toCharArray();
charTermAttr.copyBuffer(newBuffer, 0, newBuffer.length);
return true;
}
When testing the analyzer I always get a HTTP 500 response from Stanbol
server and I cannot process the enhancement response properly. But I could
successfully execute the same jersey client code above in a Java
application (in main method) and retrieve desired enhancement response from
Stanbol.
Any ideas why I always get a HTTP 500 error when invoking a rest endpoint
in Solr analyzer? Could it be a permission problem in my Solr analyzer ?
Appreciate your help.
Thanks,
Dileepa

Re: HTTP 500 error when invoking a REST client in Solr Analyzer
Posted by Dileepa Jayakody <di...@gmail.com>.
This seems to be a weird intermittent issue when I use the Analysis UI (
http://localhost:8983/solr/#/collection1/analysis) for testing my Analyzer.
It works fine when I hard code the input value in the Analyzer and index. I
gave the same input : "Tim Bernes Lee is a professor at MIT" hard coded in
the Analyzer class and from the Solr Analysis UI. The UI response failed
intermittently when I adjust the field value.
This could be a problem with character encoding of the field value it seems.
Thanks,
Dileepa
