I created a Java project in Eclipse and created a simple class with a main method.
Problem: when I run the program(without any server etc), I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/codec/DecoderException
at autoPEC.main(autoPEC.java:6)

What I tried to solve the problem: included path to commons-codec.jar in the environment variables JAVA_HOME by putting a semicolon after the jdk path
Result: class still does not run
I think that the problem could be that I am not correctly including the classpath. How should I do this?
Google the missing jar and include it in the Java Build path
Reason for this exception is missing of a jar.
please add the jar(Commons-codec.jar) file needed for this org.apache.commons.codec.DecoderException
Download it from here
http://commons.apache.org/proper/commons-codec/download_codec.cgi
then put it in your classpath

I have manually downloaded and added the libraries log4j, jsoup and neo4j for a project in Intellij Idea.
Before adding neo4j, I could build a jar as an artifact with all the libraries extracted to it so i could directly copy it somewhere and run with java -jar file.jar.
When I run the application in IntelliJ Idea it always works!
Now i get the following error when running the jar:

I already searched for the error and found that a library seems to be signed and I can't just pack it into another jar, because it thinks it was modified then.
The suggested solution was to exclude the signing files through the build system.
I tried to manually delete the BCKEY.dsa and the BCKEY.sf files (only signing files in META-INF folder) in the resulting jar but then I get the following error:

I also searched that error, a META-INF/services/org.neo4j.kernel.extension.KernelExtensionFactory file exists in my jar, there are also the jars lucene-analyzers-commen, lucene-codecs, lucene-core, lucene-queryparser, neo4j-lucene-index and neo4j-lucene-upgrade all integrated in the über-jar and the build in IntelliJ Idea seems to have enough dependencies, too.
So I'm a bit clueless why the jar doesn't work as opposed to the build in the IDE.
Long term I'm willing to switch to a build system but for now:
Is there a way to get the jar to run?
Any help or pointers in the right direction are appreciated! :)

The error is java.lang.NoClassDefFoundError
Now the Obvious reason of NoClassDefFoundError is that a particular class is not available in Classpath, so we need to add that into Classpath or we need to check why it’s not available in Classpath if we are expecting it to be.
Now the files that I have added to the classpath are the following.
export CLASSPATH=$(JARS=(./lib/*.jar); IFS=:; echo "${JARS[*]}")
export CLASSPATH=$CLASSPATH:~/.m2/repository/org/apache/httpcomponents/httpclient/4.0.1/httpclient-4.0.1.jar
export CLASSPATH=$CLASSPATH:~/.m2/repository/org/apache/httpcomponents/httpcore/4.0.1/httpcore-4.0.1.jar
export CLASSPATH=$CLASSPATH:~/.m2/repository/commons-logging/commons-logging/1.1.1/commons-logging-1.1.1.jar
export CLASSPAHT=$CLASSPATH:~/ms_thesis/ONOS/httpcore-4.1.jar
#export CLASSPATH=$CLASSPATH:~/ms_thesis/ONOS/lib/httpclient-4.2.jar
export CLASSPATH=$CLASSPATH:~/google-gson-2.2.4/gson-2.2.4.jar
What jar file should I add to find "org/apache/http/params/SyncBasicHttpParams" I am very new to java and don't know how to debug this issue.
According to the official documentation, the class that you seek is only in httpcore since 4.1. You'll want to pull a new JAR.
org/apache/http/params/SyncBasicHttpParams class is under httpcore-4.1-alpha1.jar , which can be downloaded from
http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/httpcomponents/httpcore/4.1-alpha1/httpcore-4.1-alpha1.jar
In future if you need to find a jar for a class, then you can use this link, this is generally helpful:
http://www.findjar.com/
In your case it seems to br you missing out some necessory jar files to include in your project
otherwise you any one of your linked is giving an exception mainly because of static method invocation or intialization
Here's the link to get the jar file httpcore-4.1

Now what I have done so far:
I created a libs folder in my project folder and added the Jsoup.jar there. Then in eclipse I click properties, add external Jar and added it. I see the referenced library.
But the issue still persist. I dont get compilation errors. So this is a runtime issue. Appreciate the help.
Edit:
I have found the following
If I compile using
javac -classpath /path/to/jsoup.jar myclass.java
and then
java -classpath /path/to/jsoup.jar myclass
It runs perfect.
Now. This is not working for me because I am going to use my application on a computer that does not have Jsoup. So how to I resolve this runtime issue?
Go to Run configurations... menu and check classpath for Run task. It looks like you add library for Compilation step, but it doesn't set at Run step.
Edit (after comment)
I dove into the issue and found that this dependency is needed for application container. So you just need to add this library to classpath of your app server. If you use Tomcat, just put the library to the %CATALINA_HOME%\lib directory.
I am using Ubuntu 11.04, when i start RubyMine3.1 it gave this error.

I tried every thing, i also have sun-java installed, set it default by update-java-alternatives, also my JAVA_HOME, JDK_HOME, RUBYMINE_JDK points to the sun-java directory, but still no success.
Does any one have any idea about it?
Damaged download or some classes left from older version? Try to download again and unpack into an empty directory.
Did you install any third-party plug-ins? In this case you should try to delete them from the plugins directory.
The class which fails to load is located in RubyMine/lib/util.jar. Maybe you are using an old version of rubymine.sh which doesn't add util.jar to the classpath?
I got some problems with the java. Check it out.

Wat the heck? Any idea why the first works and not the 2nd? How do I -jar my scala??
My thanks in advance, brother.
If you define -jar the -classpath is ignored:
Java manual:
-jar When you use this option, the JAR file is the source of all user
classes, and other user class path
settings are ignored.
You can define the classpath dependencies in the Manifest metadata.
The easiest way to start your app is using the scala scripts:
scala -classpath target/scaaaaaaaaala-1.0.jar scaaalaaa.App Hello World!
Simply running
scala scaaaaaaaaala-1.0.jar
works for me with 2.11.6
use sbt-assembly sbt plugin to produce a jar containing all dependencies
sbt-assembly github
e.g. add a line in project/plugins.sbt:
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.10")
adjust your build.sbt e.g. with
mainClass in (assembly) := Some("mypackage.mysubpackage.MyMainClass")
assemblyJarName in assembly := "my_assembly.jar"
then build your assembled jar with
sbt assembly
and launch it with
java -jar ./target/scala-2.12/my_assembly.jar
Et voilà, no class-path this & thats needed any more. only 1 jar.
For an executable jar, the classpath should be in the jar's manifest. For help on doing that, look through the answers to Stackoverflow: How to create an executable jar with dependancy jars.
Below is the way to execute the Scala Executable Jar
We need scala installed in your system.
Here first will give the jar path and jar name
If your code needs any dependency jar then keep all jar in one directory and give a path of this in command like below after the ":".
At last give your class/object name.
scala -cp "/your/jar/path/jar_name.jar:/your/dependency/jar/path/*"
