Java Exceptions error when trying to execute .jar on Debian Jessie

A teacher of mine created a program on java around 2005, he has always used MacOS. He sent the .jar to me and a classmate, both linux (me Debian 8 and him Ubuntu) and we can't execute the program because it returns a lot of exceptions.
At first I thought it could have been because the program was too old but my teacher can run it in his 1 year old updated mac perfectly fine.
Checked and Debian comes with OpenJDK as default. Havent installed anything, is there anything I should be installing for it to run?
PS: if I double click the .jar I can see the folders.
The exceptions are:

I don't know anything about java so please if you can try to be as basic as you can. I am also new to Debian, so I really don't know if there's a package missing from the default installation.
Edit:
The MANIFEST.MF file is
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.2
Created-By: 1.6.0_24-b07-334-10M3326 (Apple Inc.)
Class-Path: lib/Jama-1.0.2-ed.jar lib/jfreechart-1.0.6.jar lib/ant.jar
lib/jcommon-1.0.10.jar
X-COMMENT: Main-Class will be added automatically by build
Main-Class: com.cmcweb.electronicstructure.CompleteDOSPlotter

You have to download JFreeChart.jar libary (http://www.java2s.com/Code/Jar/j/Downloadjfreechartjar.htm) because your teacher didn't include external classes in his jar file.
Put JFreeChart.jar into /your_linux_path/jre/lib/ext folder and after that it should works.
P.S. The same you have to do with Jama.jar and jcommon.jar

Make sure you have all jars with the version from the manifest file downloaded in a lib directory. Lib directory should be placed in the same directory as your jar, the names of dependency jars should be exactly the same as these from classpath in manifest.
So in your case, it may not work with the newest JFreeChart version. You need to find and download version 1.0.6

Apache Ant: NoClassDefFoundError when using Junit

I just can't seem to get my junit tests run by Ant. Here's my setup:
build.xml
http://pastebin.com/c7n4cdJ6
What am I trying to do? I run ant main or ant package respectively. The compile target compiles my code. First the classes of my webapp and afterwards my test classes:
javac: source: webapp java files, destination: ${web.classes.dir}
javac: source: test java files, destination: ${web.testclasses.dir}
For dependency management I use Apache Ivy, which is working fine.
So let's take a look at my junit target. You can see that the classpath is defined in junit.classpath. It contains:
My Ivy dependencies with the test scope: <path refid="test.path"/>
The compiled class files of my tests: <pathelement location="${web.testclasses.dir}"/>
The compiled class files of my webapp: <pathelement location="${web.classes.dir}"/>
Also it contains a dirset of my compiled test classes (you see I was desperate).
So when I run the ant script it compiles well, the class files are all there. But when it comes to junit target and the first test is being executed, I get this error in the console:
[junit] Running CreateStopwordSqliteDBTest
[junit] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0 sec
BUILD FAILED
In the result xml file I get further information:
<error message="CreateStopwordSqliteDBTest (wrong name: de/mycompany/myproduct/CreateStopwordSqliteDBTest)" type="java.lang.NoClassDefFoundError">

</error>
NoClassDefFoundError tells me that the class could be found at compile time but not on runtime. Please note that the affected class is the actual JUnit test. Why can't it be found even though I made sure it is part of my junit classpath?
Fyi: When I remove the lines 131 - 133 from my build.xml (the dirset in my junit classpath), I would get a ClassNotFoundException:
<error message="CreateStopwordSqliteDBTest" type="java.lang.ClassNotFoundException">

Could you help me out here?

The source directories are wrong. Here are the correct properties:
<property name="src.dir" location="${basedir}/src" />
<property name="testsrc.dir" location="${basedir}/testsrc" />

I've run across a few notions that suggest this is an issue with the scala version. Current library list:

com.typesafe.akka:akka-osgi_2.11:2.4.0
com.typesafe.akka:akka-slf4j_2.11:2.4.0
Suggestions on where I've run astray?

The problem is indeed a Scala version mismatch. You're mixing dependencies which are built for Scala 2.11, e.g. org.apache.kafka:kafka_2.11:0.8.2.2 with Flink dependencies which are built by default for Scala 2.10.
One of the dependencies built for Scala 2.11 pulls in the scala-library:2.11 jar which replaces the scala-library:2.10 dependency required by the Flink dependencies. You either use the binaries built for Scala 2.10 for the non-Flink dependencies or you build and install Flink using Scala 2.11. See https://ci.apache.org/projects/flink/flink-docs-master/setup/building.html#build-flink-for-a-specific-scala-version for how to build Flink with different Scala version.
Kafka example
If you just want to bump the version of the referenced Kafka example to 0.10-SNAPSHOT you have to change the Flink version in the pom.xml file and you have to use the FlinkKafkaProducer instead of the KafkaSink in the WriteIntoKafka.java file. You don't need the SimpleStringSchema then anymore. That is all you have to change (no additional dependencies are required).

Deploying web app using Ant results in NoClassDefFoundError

I'm using Ant 1.9.3 and Tomcat version 8.0. I'm using the Ant deploy target to deploy web apps in the Apache Tomcat using the manager credentials. The deploy target fails with the following exception:

When I tried to find the class Base64 in the package org\apache\tomcat\util\codec\binary\ which is in tomcat-util.jar, and it is in the classpath which I've verified by an echo in Ant build file.
I'm not able to solve the issue.

Just in case someone runs into the same problem I was having:
I was following the tutorial on the Tomcat website and I ran into the same NoClassDefFoundError issue when I tried to run ant install.
The tutorial mentions that you have to copy $CATALINA_HOME/lib/catalina-ant.jar1 (which contains the implementation code for the Ant custom tasks) to the lib directory of your Ant installation.
It does not mention, however, that you need to do the same thing for tomcat-util.jar. As soon as I copied tomcat-util.jar to my Ant directory, things started working (source).
1$CATALINA_HOME is the directory of your Tomcat installation, e.g. /usr/share/tomcat8

Please make sure you have added the tomcat-util.jar in the classpath as below.
<path id="catalina-ant-classpath">
<!-- We need the Catalina jars for Tomcat -->
<!-- * for other app servers - check the docs -->
<fileset dir="${appserver.lib}">
<include name="catalina-ant.jar"/>
<include name="tomcat-util.jar"/>
</fileset>
</path>

java.lang.NoClassDefFoundError: org/apache/axis2/client/Stub

I've added a Web Service using Axis2 to my project and now I can't run my application.
This is the classpath I am using:
<property name="classpath" location="bin:EventReservationCore/bin:EventReservationCore/db:EventReservationCore/lib/*:EventReservationCore/lib/util_iso2.jar:EventReservationCore/lib/sqlitejdbc-v056.jar:AuthorizationRMI/lib/AuthorizationService.jar:EventReservationCore/lib/activemq-all-5.4.3.jar:/home/ander/axis2-1.6.1/webapp/axis2.war"/>
And this is the target that runs until I add the Axis2 Web Service.
<target name="run.besocial">
<java classname="eventReservationServer.ReservationEventServer" classpath="${classpath}" fork="true">
<jvmarg value="-Djava.rmi.server.codebase=file:EventReservationCore/bin/ file:EventReservationCore/lib/util_iso2.jar"/>
<jvmarg value="-Djava.security.policy=EventReservationCore/java.policy" />
</java>
</target>
As a result I get this error:

If you are using tomcat, copy all the jar files located under axis2/lib folder to the tomcat/lib folder and also add them to the classpath like this D:\axis2-1.6.2\lib*

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/axis2/client/Stub
Above error can be removed by adding axis2-kernel-1.6.2 to the class path, but you might start getting other errors after you have generated the stubs with wsdl2java.bat.
So you better add all the axis2-jars to classpath while compiling the client.
Hope this helps

None of the answers helped me. Here is then what I did.
I used eclipse to generate Runnable Jar(right click->Export->Runnable Jar) with all the libraries added as package.
It gave me a JAR that I could run from command line.
Then I did diff between Jar from eclipse and Jar that my build created. I was able to find the missing dependencies that my build was not putting in Jar.

If you faced the same issue for JBoss class loader, follow the tips on here and here.
The most important part is to define a new module in JBoss module configurations, and also locate the module in you MANIFEST.MF file.
Maven will help you to do the later part. Following is a sample configuration to add axis module to your Manifest file.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-ejb-plugin</artifactId>
<configuration>
<archive>
<manifestEntries> <!--Manually added JBoss Modules (that are not found by JBoss class loader) must be loaded here-->
<Dependencies>axis.axis</Dependencies>
</manifestEntries>
</archive>
</configuration>
</plugin>
Depending to your packaging type, you would use other maven plugins like maven-jar-plugin or maven-war-plugin.
The dependency package name must match the name that you have specified to your module name in JBoss modules. The above axis module is defined in JBoss models as explained in the links above.
<module xmlns="urn:jboss:module:1.1" name="axis.axis">
<properties>
<property name="jboss.api" value="private"/>
</properties>
<!-- ... -->
</module>
