XMLDB Restet Adapter/Lucene/Maven - Running/Testing
- Starting Jetty to debug these services outside OJVM
This Maven target provides a client side environment to test and debug REST WS without installing it inside the OJVM. Note that in this server side implementation of REST WS we are using a unique entry point to get the SQL connection, this connection when running outside the database use System’s properties to get user, password and SQLNet connect string to connect to the target database.

Note that LUCENE user is configured in pom.xml file, so it will passed to Jetty as System properties and used by XMLDB Restlet adapter as effective user. If you will try to test LuceneApplication using telnet scripts change LUCENE/LUCENE to scott/tiger into pom.xml file.
You can debug and test LuceneApplication.java using Restlet default servlet engine starting it as a simple Java application, but this scenary will not test XMLDB Restlet stack.
- Testing with telnet
Directory src/main/scripts have several .txt file which includes HTTP content information to test Lucene REST WS API. For example to get all Lucene Domain Indexes at SCOTT’s schema you can execute:
[mochoa@mochoa lucene-restlet]$ cat src/main/scripts/test_get_scott.txt GET /lucene/ HTTP/1.0 Authorization: Basic c2NvdHQ6dGlnZXI= Host: localhost:8080 [mochoa@mochoa lucene-restlet]$ telnet localhost 8080 Trying 127.0.0.1... Connected to live.dbprism.mochoa.dyndns.org (127.0.0.1). Escape character is '^]'. GET /lucene/ HTTP/1.0 Authorization: Basic c2NvdHQ6dGlnZXI= Host: localhost:8080 HTTP/1.1 200 OK MS-Author-Via: DAV DAV: 1,2,<http://www.oracle.com/xdb/webdav/props> Date: Wed, 18 Jun 2008 23:08:06 GMT Server: Noelios-Restlet-Engine/1.1.snapshot Content-Type: application/atomsvc+xml; charset=ISO-8859-1 Vary: Accept-Charset, Accept-Encoding, Accept-Language, Accept Content-Length: 330 Expires: Wed, 18 Jun 2008 23:08:16 GMT<?xml version="1.0" encoding="ISO-8859-1"?> <service xmlns="http://purl.org/atom/app#"> <workspace title="Lucene Web Service"> <collection href="SOURCE_BIG_LIDX/" title="Index Name: SOURCE_BIG_LIDX status: VALID"> <member-type>entry</member-type> </collection> </workspace> </service>Connection closed by foreign host.
Note that the Authorization header have a B64 encoding information of scott:tiger user/password, if your database have different values it will not work. Also we are using XMLDB default HTTP port (8080). The example shows that scott have one Lucene Domain Index named SOURCE_BIG_LIDX. This index was created using a table and index creation SQL script like:
SQL> create table test_source_big as (select * from all_source);
SQL> create index source_big_lidx on test_source_big(text)
indextype is lucene.LuceneIndex
parameters('AutoTuneMemory:true;Analyzer:org.apache.lucene.analysis.StopAnalyzer;\
MergeFactor:500;FormatCols:line(0000);ExtraCols:line "line"');

- Measuring performance using Apache JMeter
Using some of the JMeter templates at directory src/test/jmeter you can perform performance test of Lucene REST WS API over Lucene Domain Index.
