classpath

In spark job, I don't know how to import and use the jars that is shared by method SparkContext.addJar() . It seems that this method is able to move jars into some place that are accessible by other nodes in the cluster, but I do not know how to import them. This is an example: package utils; public class addNumber { public int addOne(int i){ return i + 1; } public int addTwo(int i){ return i + 2; } } I create a class called addNumber and make it into a jar file utils.jar . Then I create a spark job and codes are shown below: import org.apache.spark.SparkConf import org.apache.spark

I want to load xml files which contains some error definitions of several modules in a Spring Maven project. I want to load and then pass the file to a JAXB unmasheller.

I'm setting up a simple JDBC connection to my working MySQL database on my server. I'm using the Connector-J provided by MySQL. According to their documentation, I'm suppose to create the CLASSPATH variable to point to the directory where the mysql-connector-java-5.0.8-bin.jar is located.

But then when I open a new terminal and type echo $CLASSPATH it's no longer there. I think this is the main reason why my Java server won't connect to the

I'm using the eclipse jetty plugin in my project: <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>9.0.3.v20130506</version> I have my application that read a file in the classpath of the server, but I can't manage to put it in the Jetty classpath... I would to put it in a folder in my project and make that folder part of the Jetty classpath, how can I do it? Is there a better solution to make that file external to the application? It was just a matter of configuration of the maven plugin <configuration> <scanIntervalSeconds>10</scanIntervalSeconds>

I made a project in Eclipse and am now trying to ensure that the .java files compile from the command line. I've been trying to compile using javac *.java in the folder with all my .java files. However, this results in errors due to a reference to a class from an external library, Joda-time.
