I am getting java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory when I start my web application.
As you can see in the image below, I have tomcat-juli.jar in my classpath for the Tomcat server configuration but it's still not working.

How can I solve this?
Put the tomcat-juli.jar in a path (the lib directory) that Tomcat use to load classes. If your Tomcat does not find it you can copy the jar in the lib directory of the JRE that you are using.
Okay, I had to add the tomcat-juli.jar to the classpath in the run configuration for the actual Java Application. All the answers I saw on the internet just pointed out that the Tomcat server needs this in his classpath (see my question).
Try export CLASSPATH=/usr/share/tomcat8/lib/tomcat-juli.jar.
You can find more information Here
I am seeing you are adding path as /usr/share/tomcat8/bin instead of /usr/share/tomcat8/lib/ Please check this also

I am not particularly well experienced with Java at all and try to get a jar file running on my Ubuntu machine (https://sites.google.com/site/communitydetectionslpa/home).
However once I run the jar file with the command suggested by developers I receive the following error:
java -jar GANXiSw.jar -i test.ipairs

Apparently java is not able to import the org.apache.commons class properly. After some researching I checked if I have libcommons-collections3-java installed, which however is the case.
I read something about adding the library explicitly to my CLASSPATH, which however I also read to be not good practice.
What is the best approach to fix my issue?
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! :)
I am using hadoop 2.4.1 version. I am trying to run a mapreduce job which moves data from local system to hdfs cluster(output directory). If I set the output directory as my local system path, the program is running fine. But when I set the output directory as a path in hdfs cluster I am getting the below error

I saw some posts which stated the issue could be related to protobuf dependecy.
Hadoop 2.2.0 mapreduce job not running after upgrading from hadoop 1.0.4
I am using hadoop commons jar 2.5.2 which has the protobuf. Any help to solve this would be appreciated.
Made it working ! Found that there were some jars of 2.2 version which were incompatible with the current version. When i updated those, the program works fine.
if you compile zhe *.java use default java CLASSPATH is ok.
Edit the hadoop_env.sh
export HADOOP_CLASSPATH=${CLASSPATH}
restart the hadoop server
NoClassDefFoundError is thrown by jvm at runtime when a class is not present in classpath.
Check your classpath.
Check also this answer. Could be useful if you solved the NoClassDefFoundError link

I've seen on the other posts that this is due to the fact that the driver is not in the lib directory of the JDK. I tried that and it still doesn't work. I added the *.jar file to my "/usr/lib/default-java/lib/" folder on Xubuntu. I am not using any kind of servers. Here is my code that connects to the database:
Class.forName("com.mysql.jdbc.Driver");
Does anyone know what I am missing here?
Thanks for all the help in advance.
If you are using eclipse or some ide you can add the jar files to your build path.
It can be done by checking this link for eclipse. https://stackoverflow.com/a/27085441/4083590
If you are using command prompt you should add the jar files to your CLASSPATH. It can be done as shown below.
Linux:
CLASSPATH=$CLASSPATH;{Current working directory};{Direct Path to .jar file}
CLASSPATH=$CLASSPATH;/home/users/xyz/workspace/;/home/users/xyz/workspace/xyz.jar
Note: ./ can be used to signify current working directory
Windows:
set CLASSPATH=%CLASSPATH%:{Current working directory}:{Direct path to .jar file}
set CLASSPATH=%CLASSPATH%:C:\users\xyz\workspace:C:\users\xyz\workspace\xyz.jar
After doing this you would be able to compile your program.

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
