multithreading - Random Neo4j database location for Embedded Jersey Tests -

i'm using com.sun.jersey.test.framework.jerseytest create junit tests jersey application. application uses neo4j spring data load data , return via rest api.

the test starts embedded grizzly server jersey neo4j spring data webapp. after i'm able invoke rest requests , create nodes in neo4j database. unfortunately test fixed single neo4j database location since configured within applicationcontext.xml so:

<neo4j:config storedirectory="/tmp/myapp/neo4jdb" />  

my test fail if excute similar test @ same time because same directory used , 1 neo4j can obtain lock.

i know springjunit4classrunner can't use because have neo4j instance running within embedded server.

@contextconfiguration(locations = "classpath:/spring/applicationcontext.xml") @runwith(springjunit4classrunner.class) @transactional 

the test should create neo4j database in random directory.

questions:

• is there way change storedirectory , clear neo4j database. changing storedirectory in setuponce well.
• is there way clear neo4j database. (i can't autowire in test because not part of spring context)

i'm using java-based bean configuration:

package com.gentics.sandboxmanager.service;  import java.io.file; import java.io.ioexception; import java.nio.file.files;  import org.neo4j.kernel.embeddedgraphdatabase; import org.springframework.context.annotation.bean; import org.springframework.context.annotation.configuration; import org.springframework.data.neo4j.config.enableneo4jrepositories; import org.springframework.data.neo4j.config.jtatransactionmanagerfactorybean; import org.springframework.data.neo4j.config.neo4jconfiguration; import org.springframework.data.neo4j.support.neo4jexceptiontranslator; import org.springframework.data.neo4j.support.neo4jtemplate; import org.springframework.data.neo4j.support.mapping.neo4jmappingcontext;  @enableneo4jrepositories(basepackages = "com.gentics.sandboxmanager.repository") @configuration public class neo4jconfig extends neo4jconfiguration {      private static file databaselocation;     private static embeddedgraphdatabase neo4jdb;      /**      * returns neo4j database      *       * @return      */     public static embeddedgraphdatabase getneo4jdatabase() {         return neo4jdb;     }      @bean     public embeddedgraphdatabase graphdatabaseservice() throws ioexception {          // todo use properties app not use temp dir         databaselocation = files.createtempdirectory("neo4j").tofile();         databaselocation.deleteonexit();          neo4jdb = new embeddedgraphdatabase(databaselocation.getabsolutepath());         return neo4jdb;     }      @bean     public neo4jtemplate neo4jtemplate() throws ioexception {         return new neo4jtemplate(graphdatabaseservice());     }      @bean     public neo4jmappingcontext neo4jmappingcontext() {         return new neo4jmappingcontext();     }      @bean     public jtatransactionmanagerfactorybean transactionmanager() throws exception {         return new jtatransactionmanagerfactorybean(graphdatabaseservice());     }      @bean     public neo4jexceptiontranslator exceptiontranslator() {         return new neo4jexceptiontranslator();     }  } 

each jerseytest testcase restart webapp. neo4j therefore use empty neo4j database.
