I am trying to use this code below to fix my "Error: No manifest attribute", when I try to run my jar file that has external dependencies instead of it.
<build>

<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>Driver</mainClass>
</manifest>
</archive>
</configuration>
...
</plugin>
</plugins>
However, every time I clean, then compile, then package it and run the jar. It keeps saying:
Error: Could not find or load main class com.harriott.Driver
Caused by: java.lang.ClassNotFoundException: Driver
P.S. I only have one class with a Public static void main method, and it is named Driver:

I tried to connect to MySQL database:
public class Main {
public static void main(String[] args) {
String url = "jbdc:mysql://localhost:3306/mydb?autoReconnect=true&useSSL=false";
String user = "root";
String password = "root";
try{
Connection myConn = DriverManager.getConnection(url,user,password);
} catch (SQLException e) {
e.printStackTrace();
}
}
}
And i get this error:
java.sql.SQLException: No suitable driver found for jbdc:mysql://localhost:3306/mydb?autoReconnect=true&useSSL=false
Any ideas on how to fix it?
Got it.
There's a typo in your JDBC URL. It should be 'jdbc' instead of 'jbdc'.
String url = "jdbc:mysql://localhost:3306/mydb?autoReconnect=true&useSSL=false";
I am very new to Neo4j and I'd like to get started with an embedded Neo4j in a Java Application. I try to run a HelloWorld Application as follows.
import org.neo4j.driver.AuthTokens;
import org.neo4j.driver.Driver;
import org.neo4j.driver.GraphDatabase;
import org.neo4j.driver.Session;
import org.neo4j.driver.Result;
import org.neo4j.driver.Transaction;
import org.neo4j.driver.TransactionWork;
import static org.neo4j.driver.Values.parameters;
public class HelloWorldExample implements AutoCloseable
{
private final Driver driver;
public HelloWorldExample( String uri, String user, String password )
{
driver = GraphDatabase.driver( uri, AuthTokens.basic( user, password ) );
}
#Override
public void close() throws Exception
{
driver.close();
}
public void printGreeting( final String message )
{
try ( Session session = driver.session() )
{
String greeting = session.writeTransaction( new TransactionWork<String>()
{
#Override
public String execute( Transaction tx )
{
Result result = tx.run( "CREATE (a:Greeting) " +
"SET a.message = $message " +
"RETURN a.message + ', from node ' + id(a)",
parameters( "message", message ) );
return result.single().get( 0 ).asString();
}
} );
System.out.println( greeting );
}
}
public static void main( String... args ) throws Exception
{
try ( HelloWorldExample greeter = new HelloWorldExample( "bolt://localhost:7687", "neo4j", "password" ) )
{
greeter.printGreeting( "hello, world" );
}
}
}

Unfortunately I cannot run the code it raises "Exception in thread "main" java.lang.Error: Unresolved compilation problem: at HelloWorldExample.main(HelloWorldExample.java:46)". Additionally, when hovering over the import lines I see "import org.neo4j cannot be resolved".
Can somebody provide information about this?
As documented, in order to use neo4j's Java driver, you need to specify the appropriate dependency:
<dependency>
<groupId>org.neo4j.driver</groupId>
<artifactId>neo4j-java-driver</artifactId>
<version>x.y.z</version>
</dependency>
The latest release version is 4.0.1.
[UPDATE]
Also, your pom.xml file has a lot of other issues. Try something like this instead:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

<dependency>
<groupId>org.neo4j.driver</groupId>
<artifactId>neo4j-java-driver</artifactId>
<version>4.0.1</version>
</dependency>

</project>
This example POM file uses some dummy groupId, artifactId, and version values for itself (near the top). You should replace them with your own values (not values belonging to neo4j).

I've got an embeded OSGi framework (Felix).
I'm installing the basic bundles without problem, I can access the Felix webconsole.
But starting libra-commons-osgi-core-wsbundle-1.4.0.war gives me this error :
"org.osgi.framework.BundleException: Unable to resolve hu.libra.commnos.osgi.core.wsbundle [9](R 9.0): missing requirement [hu.libra.commnos.osgi.core.wsbundle [9](R 9.0)] osgi.wiring.package; (osgi.wiring.package=hu.libra.commnos.osgi.core.service) Unresolved requirements: [[hu.libra.commnos.osgi.core.wsbundle [9](R 9.0)] osgi.wiring.package; (osgi.wiring.package=hu.libra.commnos.osgi.core.service)]"
hu.libra.commnos.osgi.core.service bundle is installed and started (Felix webconsole shows bundle as Active and shows the registered service)
hu.libra.commnos.osgi.core.service\META-INF\MANIFEST.MF contains

I installed hadoop,hbase and phoenix in ubuntu 14 and runed a simple example for connecting phoenix in eclipse. It's work and execute my query.
public static void execute() throws ClassNotFoundException {
Connection connection = null;
Statement statement = null;
ResultSet rs = null;
PreparedStatement ps = null;
try {
connection = DriverManager.getConnection("jdbc:phoenix:localhost");
statement = connection.createStatement();
// Query for table
ps = connection.prepareStatement("select * from dum.user_info where id=25 ");
rs = ps.executeQuery();
System.out.println("Table Values");
while (rs.next()) {
Integer myKey = rs.getInt(1);
String myColumn = rs.getString(2);
System.out.println("\tRow: " + myKey + " = " + myColumn);
System.out.println("" + rs.getString(3) + " " + rs.getString(4) + " " + rs.getString(5) + " "
+ rs.getString(6) + " " + rs.getString(7));
}
} catch (SQLException e) {
e.printStackTrace();
}
}
Now I'd like to run a web application that connect to phoenix.
I installed tomcat and create a web dynamic application, I can run it and view page in browser but when I add execute function, it doesn't work.
public class LoginServlet extends HttpServlet {
private LoginService userValidationService = new LoginService();
private TodoService todoService = new TodoService();
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
try {
phoenixHelper.execute();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
request.getRequestDispatcher("/WEB-INF/views/login.jsp").forward(
request, response);
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
String name = request.getParameter("name");
String password = request.getParameter("password");
boolean isUserValid = userValidationService.isUserValid(name, password);
if (isUserValid) {
request.getSession().setAttribute("name", name);
response.sendRedirect("/list-todos.do");
} else {
request.setAttribute("errorMessage", "Invalid Credentials!");
request.getRequestDispatcher("/WEB-INF/views/login.jsp").forward(
request, response);
}
}
}
I faced this error:
java.sql.SQLException: No suitable driver found for jdbc:phoenix:localhost
Can anybody tell me how to run a web application that connect to phoenix?
It's pom.xml.

Try loading the driver before creating the connection.
Class.forName("org.apache.phoenix.jdbc.PhoenixDriver");
