Unable to connect to Google Cloud SQL with eclipse - java

I'm having trouble connecting to my database from eclipse. The mysql java connector & the mysql socket factory connector jar files are included in the build path. I'm not sure what is causing the NoClassDefFound error. The credentials are correct and omitted in the code.
My code:
import java.sql.*;
public class TestConnect {
private static String instanceConnectionName = "sampleInstanceName";
private static String databaseName = "sampleDatabaseName";
private static Connection connection = null;
private static String userName="sampleUserName";
private static String password="samplePassword";
private static String dbURL = String.format("jdbc:mysql://google/%s?cloudSqlInstance=%s&"
+ "socketFactory=com.google.cloud.sql.mysql.SocketFactory",
databaseName, instanceConnectionName);
public static void main(String[] args) {
// TODO Auto-generated method stub
try {
Class.forName("com.mysql.jdbc.Driver");
} catch (Exception e) {
System.out.println("Where is your MySQL JDBC Driver?");
e.printStackTrace();
return;
}
System.out.println("MySQL JDBC Driver Registered!");
CreateConnection();
}
public static void CreateConnection() {
try {
// connect
connection = DriverManager.getConnection(dbURL,userName, password);
} catch (SQLException ex) {
System.out.println("Connection Failed! Check output console");
ex.printStackTrace();
}
}
}
Here is the pom.xml:

com.mysql.cj.api.io.SocketFactory is part of the MySQL Connector/J version 6. This is used by the SocketFactory in the mysql-socket-factory-connector-j-6. However the pom.xml you shared, uses mysql-socket-factory which is the version 5 packet and shouldn't use it.
Is it possible that you used mysql-socket-factory-connector-j-6 previously and it is in your libraries from that? This could allow the v6 SocketFactory to be loaded by mistake, causing this issue. If so try mvn clean to get rid of the old jar file and try running again.

Simple Spring Cloud config server is not starting up-java.lang.ClassNotFoundException: ConfigDataMissingEnvironmentPostProcessor

I downloaded one config project from start.spring.io. added #EnableConfigServer added 3-4 properties git URI, application name and port but while starting up the server is not getting started. I tried with 3 different spring boot version, everywhere I am getting error. What can be done?

looks like you have a dependency missing in your pom.xml
try adding spring-cloud-commons:
<dependency>

ClassNotFoundException: org.apache.xerces.parsers.AbstractSAXParser when using boilerpipe

I am very new to boilerpipe and I am trying out the following basic code:
package contentExtraction;
import java.net.URL;
import de.l3s.boilerpipe.extractors.ArticleExtractor;
public class ContentExtractor {
public static void main(String[] args) throws Exception {
final URL url = new URL(

"http://www.dn.se/nyheter/vetenskap/annu-godare-choklad-med-hjalp-av-dna-teknik"
);
System.out.println(ArticleExtractor.INSTANCE.getText(url));
}
}
But I am getting the following error when trying to run the above piece of code:

I googled the error and came across this link. I thought that I was missing xercesImpl.jar in my dependencies. I included the same, still my code is giving the same error. What is the issue?

I figured the solution myself. The boilerpipe jar has further dependencies. I converted my project to maven project, included the dependency:
<dependency>
<groupId>com.syncthemall</groupId>
<artifactId>boilerpipe</artifactId>
<version>1.2.1</version>
</dependency>
When I build the above project, I can see there are actually 4 jars that are imported in Maven Dependencies folder:
boilerpipe-1.2.1.jar
nekohtml-1.9.18.jar
xercesImpl-2.11.0.jar
xml-apis-1.4.01.jar

ClassNotFoundException when starting Spring Boot app

I am getting ClassNotFoundException exception when I package my code with maven and then start it with:

I can see that in my "fat jar" is folder lib with all dependencies and I can find there manually the class which throws ClassNotFoundException.

And it works when I run the class from my IDE but it throws ClassNotFoundException when I run it from command line.
Any ideas what may cause this?
Thanks

EDIT 2
I can see this line in the log file and the jar(activejdbc-1.4.10-SNAPSHOT.jar) with org.javalite.activejdbc.Model is there. JarLauncher must be somehow unable to load it.

I found the issue. The problem was in Guava Reflection. I use it to find all entities but classInfo.load() throws NoClassDefFoundError for "fat jar".
I fixed like this: (see NEW LINE and ORIGINAL LINE)
public static Set<Class<? extends Model>> getAllEntities() throws ClassNotFoundException {
Set<Class<? extends Model>> allEntities = new HashSet<>();
Set<ClassPath.ClassInfo> classes;
try {
classes = ClassPath.from(Application.class.getClassLoader()).getTopLevelClassesRecursive("me.factorify.server");
} catch (IOException e) {
throw new RuntimeException(e);
}
for(ClassPath.ClassInfo classInfo : classes) {
// NEW LINE
Class<?> clazz = Application.class.getClassLoader().loadClass(classInfo.getName());
//ORIGINAL LINE Class<?> clazz = classInfo.load();
if (Model.class.isAssignableFrom(clazz)){
allEntities.add((Class<? extends Model>) clazz);
}
}
return allEntities;
}

java.lang.NoClassDefFoundError: org/eclipse/jetty/server/nio/SelectChannelConnector using com.j256.simplejmx.web.JmxWebServer

I am trying to implement simple JMX Client/Server using com.j256.simplejmx. I want to spy my objects using Web Browser. I copied a really simple piece of code:
package com.my.package.jmx;
import com.j256.simplejmx.web.JmxWebServer;
public class JMXServer {
public static void main(String[] args) throws Exception {
JmxWebServer jmxWebServer = new JmxWebServer(8123);
jmxWebServer.start();
}
}
When I run it I have got an exception:
Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/jetty/util/thread/ThreadPool

</dependency>
I run it once again and I have got an another excpetion:
Ex

So once again, I update my pom.xml:
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-server</artifactId>
<version>9.1.3.v20140225</version>
</dependency>
And it gives me an error once again:

and I cannot find any solution for that. What else I should add to my pom.xml file? Maybe it is an issue with versions of dependencies?
Thank you in advance.
I edited my pom.xml
<project...>
<properties>
<jetty-version>8.1.9.v20130131</jetty-version>
</properties>
<dependencies>
<dependency>
<groupId>com.j256.simplejmx</groupId>

<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-server</artifactId>
<version>${jetty-version}</version>
<optional>true</optional>
</dependency>
</dependencies>
</project>
Now, I can run this server:
INFO Server - jetty-8.1.9.v20130131
INFO AbstractConnector - Started SelectChannelConnector#0.0.0.0:8123
but when I go to my Web Browser and I put:
localhost:8123
it thows an exception:

So right now SimpleJMX has an optional dependency for 8.1.9.v20130131 Jetty to support publishing JMX over web/HTTP. If you check out the pom.xml you'll see:
<jetty-version>8.1.9.v20130131</jetty-version>
...
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-server</artifactId>
<version>${jetty-version}</version>
<optional>true</optional>
</dependency>
Can you try this version of Jetty? I'm not sure there is a way for me to support both 8.X.X and 9.X.X but I'll look into it.
