I know is dependency mismatch and gave tried every permutation of firebase admin and firestore + guava version but no luck .
My current POM is :

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?

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:

public class TestConnect {
private static String instanceConnectionName = "sampleInstanceName";
private static String databaseName = "sampleDatabaseName";
private static Connection connection = null;

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);

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.
I have used all poi jars but still i ame getting this error

Sounds like you do not have the correct dependencies in you project.
POIXMLTypeLoader comes with POI 3.14-Beta1 and the ooxml-schemas:1.3 reference that class.You have the following options, you can add any of this dependency in your project:
use poi 3.14 beta1
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.14</version>
</dependency>
use ooxml-schemas 1.2

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
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
at com.my.package.jmx.JMXServer.main(JMXServer.java:9)
Caused by: java.lang.ClassNotFoundException: org.eclipse.jetty.util.thread.ThreadPool

I added this to my pom.xml:
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-util</artifactId>
<version>9.1.3.v20140225</version>
</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:
Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/jetty/server/nio/SelectChannelConnector
at com.mu.package.jmx.JMXServer.main(JMXServer.java:9)

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>
<artifactId>simplejmx</artifactId>
<version>1.8</version>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-util</artifactId>
<version>${jetty-version}</version>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-server</artifactId>
<version>${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.
