Thrift interface

see thrift/BoilerpipeService.thrift

enum ExceptionCode{
    ENCODING = 2,
    GENERIC = 3,

exception ExtractorException{
    1: ExceptionCode code,
    2: string message,
    3: string trace,

enum ExtractorType{
    DEFAULT = 1,
    ARTICLE = 2,
    DEBUG = 5, // dummy keep everything extractor

service ExtractorService{

    // debugging utility
    string ping(1: string input),

    // service endpoint
    string extract_string(1: string html_string, 2: ExtractorType etype)
        throws (1: ExtractorException e),

    // service endpoint
    string extract_binary(1: binary html_data, 2: string encoding, 3: ExtractorType etype)
        throws (1: ExtractorException e),


Use maven to generate java source files via thrift compiler

mvn generate-sources

or just run the usual

mvn install

Maven was also configured to produce a single .jar archive with a runnable endpoint indicated in its manifest file.

Now we can take a look at the help text

$ java -jar target/boilerpipe-thrift-x.x.x-jar-with-dependencies.jar -h

usage: Thrift
 -c,--compact      Use the compact protocol
 -f,--framed       Use framed transport
 -h,--help         Print help information
 -threadpool       Use the TThreadPoolServer. This is the default.
 -hsha             Use the THsHaServer. This implies the framed transport.
 -nonblocking      Use the TNonblockingServer. This implies the framed
 -p,--port <arg>   Port to bind to [default: 9999]

Notice that you can use the command line flags to configure your server. This configuration mechanism currently supports (similar to the Hadoop HBase thrift service configuration):


  • thread pool server
  • non blocking server
  • HsHa server (Half-Sync/Half-Async)


  • compact protocol
  • binary protocol


  • framed transport
  • server dependent transport

Example: to fire up a nonblocking server on port 9988 using the required framed transport, do

$ java -jar target/boilerpipe-thrift-x.x.x-jar-with-dependencies.jar -nonblocking -p 9988

This will imply the framed transport without using the additional flag.
