Users may also use the EntityManager API outside the container by creating a EntityManagerFactory for a given persistence unit name and properties map (includes database information etc.)
EntityManagerFactory emf = Persistence.createEntityManagerFactory(persistenceUnitName, propertiesMap); EntityManager em = emf.createEntityManager();
JavaSE Configuration using Property Map
When a simple persistence unit configuration is defined which relies on container deployment:
<persistence-unit name="employee" transaction-type="RESOURCE_LOCAL"> <non-jta-data-source>jdbc/MyDS</non-jta-data-source> </persistence-unit>
In order to test this persistence unit outside of the container the JavaSE bootstrapping API must be used. the following code can be used to customize the configuration:
Invalid language.
You need to specify a language like this: <source lang="html4strict">...</source>
Supported languages for syntax highlighting:
4cs, 6502acme, 6502kickass, 6502tasm, 68000devpac, abap, actionscript, actionscript3, ada, algol68, apache, applescript, apt_sources, arm, asm, asp, asymptote, autoconf, autohotkey, autoit, avisynth, awk, bascomavr, bash, basic4gl, bf, bibtex, blitzbasic, bnf, boo, c, c_loadrunner, c_mac, caddcl, cadlisp, cfdg, cfm, chaiscript, cil, clojure, cmake, cobol, coffeescript, cpp, cpp-qt, csharp, css, cuesheet, d, dcl, dcpu16, dcs, delphi, diff, div, dos, dot, e, ecmascript, eiffel, email, epc, erlang, euphoria, f1, falcon, fo, fortran, freebasic, freeswitch, fsharp, gambas, gdb, genero, genie, gettext, glsl, gml, gnuplot, go, groovy, gwbasic, haskell, haxe, hicest, hq9plus, html4strict, html5, icon, idl, ini, inno, intercal, io, j, java, java5, javascript, jquery, kixtart, klonec, klonecpp, latex, lb, ldif, lisp, llvm, locobasic, logtalk, lolcode, lotusformulas, lotusscript, lscript, lsl2, lua, m68k, magiksf, make, mapbasic, matlab, mirc, mmix, modula2, modula3, mpasm, mxml, mysql, nagios, netrexx, newlisp, nsis, oberon2, objc, objeck, ocaml, ocaml-brief, octave, oobas, oorexx, oracle11, oracle8, otj, oxygene, oz, parasail, parigp, pascal, pcre, per, perl, perl6, pf, php, php-brief, pic16, pike, pixelbender, pli, plsql, postgresql, povray, powerbuilder, powershell, proftpd, progress, prolog, properties, providex, purebasic, pycon, pys60, python, q, qbasic, rails, rebol, reg, rexx, robots, rpmspec, rsplus, ruby, sas, scala, scheme, scilab, sdlbasic, smalltalk, smarty, spark, sparql, sql, stonescript, systemverilog, tcl, teraterm, text, thinbasic, tsql, typoscript, unicon, upc, urbi, uscript, vala, vb, vbnet, vedit, verilog, vhdl, vim, visualfoxpro, visualprolog, whitespace, whois, winbatch, xbasic, xml, xorg_conf, xpp, yaml, z80, zxbasic
import static org.eclipse.persistence.config.PersistenceUnitProperties.*; ... Map properties = new HashMap(); // Ensure RESOURCE_LOCAL transactions is used. properties.put(TRANSACTION_TYPE, PersistenceUnitTransactionType.RESOURCE_LOCAL.name()); // Configure the internal EclipseLink connection pool properties.put(JDBC_DRIVER, "oracle.jdbc.OracleDriver"); properties.put(JDBC_URL, "jdbc:oracle:thin:@localhost:1521:ORCL"); properties.put(JDBC_USER, "scott"); properties.put(JDBC_PASSWORD, "tiger"); properties.put(JDBC_READ_CONNECTIONS_MIN, "1"); properties.put(JDBC_WRITE_CONNECTIONS_MIN, "1"); // Configure logging.

Now the PU can be instantiated for testing using:
Persistence.createEntityManagerFactory(unitName, properties);
