my local neo4j db path is C:\neo4j-community-1.9.3_bup
I have created a simple java program to connect to neo4j DB and insert some nodes.
But after insertion when
i am trying to retrive these nodes through Neo4jDataBrower these are not listing.
The code i have used is taken from neo4j portal itself,
String DB_PATH = "C\\neo4j-community-1.9.3_bup";
Map<String, String> config = new HashMap<String, String>();
config.put( "neostore.nodestore.db.mapped_memory", "10M" );
config.put( "string_block_size", "60" );
config.put( "array_block_size", "300" );
graphDb = new GraphDatabaseFactory().newEmbeddedDatabaseBuilder(DB_PATH).setConfig(config).newGraphDatabase();
registerShutdownHook( graphDb );
Transaction tx = graphDb.beginTx();
try
{
firstNode = graphDb.createNode();
firstNode.setProperty( "message", "Hello, " );
secondNode = graphDb.createNode();
secondNode.setProperty( "message", "World!" );
relationship = firstNode.createRelationshipTo( secondNode, RelTypes.KNOWS );
relationship.setProperty( "message", "brave Neo4j " );
tx.success();
}
finally
{
tx.finish();
}
Why its not working?
please suggest me..is there some problem vth path i have given or problem vth code?

C\\neo4j-community-1.9.3_bup is not a valid path. It should be C:\\neo4j-community-1.9.3_bup.
But still, it may not be valid, if you are pointing to your Neo4J installation directory, and not the database directory itself. If that is the case, the path should be C:\\neo4j-community-1.9.3_bup\data\graph.db
Edited:
To prevent the locking situation, stop your running Neo4J instance, and start your own database with its own web console, by inserting these lines after the line where you initialize your embedded database:
Configurator configurator = new ServerConfigurator((GraphDatabaseAPI)graphDb);
configurator.configuration().setProperty(Configurator.WEBSERVER_ADDRESS_PROPERTY_KEY, "127.0.0.1");
configurator.configuration().setProperty(Configurator.WEBSERVER_PORT_PROPERTY_KEY, 7474);
WrappingNeoServerBootstrapper bootstrapper = new WrappingNeoServerBootstrapper((GraphDatabaseAPI)graphDb, configurator);
bootstrapper.start();

I newly start to work with neo4j.when I want to connect to existing db on windows everything work fine, my app find db and run my business, but in Linux I catch Error starting org.neo4j.kernel.impl.factory.CommunityFacadeFactory, /opt/neo4j-community-3.0.0-M04/data/databases/graph.db exception.
I use version 2.3.3
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j</artifactId>
<version>2.3.3</version>
</dependency>
my code:
GraphDatabaseService graphDb = null;
try {
// graphDb = new GraphDatabaseFactory().newEmbeddedDatabase("/opt/neo4j-community-3.0.0-M04/data/databases/graph.db");
graphDb = new GraphDatabaseFactory().newEmbeddedDatabaseBuilder(new File("/opt/neo4j-community-3.0.0-M04/data/databases/graph.db")).
setConfig("org.neo4j.server.database.location", "/opt/neo4j-community-3.0.0-M04/data/databases/graph.db").
setConfig("allow_store_upgrade","true").
// loadPropertiesFromFile("/opt/neo4j-community-3.0.0-M04/conf/neo4j.conf").
newGraphDatabase();
} catch (Exception e) {
System.out.println("e = " + e.getMessage());
e.printStackTrace();
}
registerShutdownHook(graphDb);
how can I connect to existing db in linux.
thank you.

I assume it is caused by a timeout, as it only appears when instantiating a large number of nodes (> 100K). However, I do not find a way to set up any timeout using the setConfig/GraphDatabaseSettings APIs (unfortunately we cannot use a property file):
public GraphDatabaseService graphDatabaseService() {
GraphDatabaseService graphDb = new GraphDatabaseFactory()
.newEmbeddedDatabaseBuilder("db/my.db")
.setConfig( GraphDatabaseSettings.nodestore_mapped_memory_size, "10M" )
.newGraphDatabase();
Do you know what is the root cause of the issue and how to circumvent it?
Thanks

I created sample class Testws with one simple method sayHi(String name) that simply showing welcome message. The target is to create web service application for this class and applying OWSM policies.
All the needed file is generated from Jdeveloper 11.1.1.7 and I added the oracle/wss_username_token_client_policy to the client side in TestwsPortClient. Problem is that when I run the main method from TestwsPortClient I got the following error:
SEVERE: java.io.FileNotFoundException: .\config\jps-config.xml (The system cannot find the path specified)
Although I tried (But it did not work) to set the system propriety to find the missing file as follow:
System.setProperty("oracle.security.jps.config",
"C:\\Users\\user\\AppData\\Roaming\\JDeveloper\\system11.1.1.7.40.64.93\\DefaultDomain\\config\\fmwconfig\\jps-config.xml");
Here is the Client Class TestwsPortClient:
public static void main(String[] args) {
testwsService = new TestwsService();
SecurityPoliciesFeature securityFeatures =
new SecurityPoliciesFeature(new String[] { "oracle/wss_username_token_client_policy" });
Testws testws = testwsService.getTestwsPort(securityFeatures);
// Add your code to call the desired methods.
System.setProperty("oracle.security.jps.config",
"C:\\Users\\user\\AppData\\Roaming\\JDeveloper\\system11.1.1.7.40.64.93\\DefaultDomain\\config\\fmwconfig\\jps-config.xml");
List<CredentialProvider> credProviders =new ArrayList<CredentialProvider>();
String username = "weblogic";
String password = "weblogic1";
CredentialProvider cp =new ClientUNTCredentialProvider(username.getBytes(), password.getBytes());
credProviders.add(cp);
Map<String, Object> rc = ((BindingProvider)testws).getRequestContext();
rc.put(WSSecurityContext.CREDENTIAL_PROVIDER_LIST, credProviders);
testws.sayHi("Salman");
}
Here the exception stack trace:
Note: the stack trace is too long this is just part of it where I think it will gives an idea about the error

I have a Sonar server which is used once a day from maven/jenkins and every few days, say every 4 or 5 days, it crashes and and shows the message "We're sorry, but something went wrong".
In the log, the error is always about a jdbc connection problem. I thought that it was a problem with the database but then if I restart the sonar server everything goes fine again.
So, it looks like a memory leak or something in the sonar server that makes it crash every few days until someone restarts it. Does that makes sense?. This is the configuration I have:
sonar.jdbc.username: xxxx
sonar.jdbc.password: xxxx
sonar.jdbc.url: jdbc:mysql://x.x.x.x:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true
#----- Connection pool settings

sonar.jdbc.timeBetweenEvictionRunsMillis: 30000
sonar.updatecenter.activate=true
http.proxyHost=xxxx
http.proxyPort=3128
sonar.notifications.delay=60
That's it. And this is the error log:

Any help will be appreciated :)
This sounds familiar to me :P Try asking your operators if they have some automated 'cleansing' operation that just kills periodically open database connections automatically in order to prevent leaked connections to the database.
It happened to me, in a Windows 2012 Server and SQL Server 2012 database in a different server. It seems that sonar service maintains a connection open, created at start up time, so any disconnection (networking, database restart, etc.) causes this unrecoverable connection problem. Restarting the Sonar (SonarQube) Windows service solved the problem to me. But, if this problem is frequent, as in your case, it would be a good idea to schedule a service restart task, or find out what is taking the connection down.
I'm a newbie of java programming, and I'm trying to learning.
I have a database mysql and I manage the connection with connection Pool, BoneCP is the library that I use.
The code for create a Pool is this:
BoneCPConfig config = new BoneCPConfig(); // create a new configuration object
config.setJdbcUrl( R.database.url + R.database.dbName ); // set the JDBC url
config.setUsername( R.database.userName ); // set the username
config.setPassword( R.database.password ); // set the password
config.setMinConnectionsPerPartition(2);
config.setMaxConnectionsPerPartition(5);
config.setPartitionCount( 3 );
try{
connectionPool = new BoneCP( config ); // setup the connection pool
}catch( Exception e ){
System.out.println( e );
}
When i need the connection for send query to DB i catch the connection with this line of code:
conn = R.database.connectionPool.getConnection();
I think is all ok at this point and I haven't any errors.
After a min the console say this:

This is the strange problem!!
Thank very much!!
No suitable driver found for jdbc:mysql://localhost:3306/test_db
This seems to imply that you don't have a java MySQL JDBC driver on your classpath, have a look at the available connectors for MySQL and make sure the appropriate JAR including this driver is on your classpath.
