i've got a problem when i try to deploy a job to my talend enterprise server. When i run the job in the talend administration center i get the following error:
java.lang.NoClassDefFoundError: javax/xml/rpc/encoding/SerializerFactory

In this job im using some external jar files (axis.jar and jaxrpc.jar) and i added a tLibraryLoad in the job but without any import commands. I used a locate on the Talend Server to ensure that the needed files are located on the server. I found them in different directories and now im not sure if they have to be relocated. The directories are the followed:
{Talend-Installation}/cmdline/studio/commandline-workspace/.Java/lib/jaxrpc.jar
{Talend-Installation}/cmdline/studio/configuration/lib/java/jaxrpc.jar
{Talend-Installation}/cmdline/studio/plugins/javax.xml.rpc_[version]/lib/jaxrpc.jar
{Talend-Installation}/studio/plugins/javax.xml.rpc_[version]
On my client the job runs without any errors. Can someone help me with that?
Don't hesitate to ask me for additional content if needed.
Cheers.
External libreries have to be in the same machine where the job will be executed, therefore in order to make it run,
Use a context variable in the component tLibraryLoad : context.my_jar_path+"/jaxrpc.jar"
Put the jars files in the execution server
Depending to how you load your context, make the context variable have the value of the jar path: context.my_jar_path = /Data/Talend/ExtJars/

I've got a serious problem with my Raspberry Pi (OS: Raspbian) and Java (JDK-7-Armhf). My code wont execute without creating a Exception.
I'll been reading and trying several proposals and nothing have worked yet.
So now i am confused of what went wrong..?
So it goes like this:
I've got a Java source code that will run in my Eclipes IDE.
But when i export the .jar-file, even with library (JRE System lib. _86, JavaSE1.7, JAVAX.comm), as "Runnabel JAR" or just .JAR and execute it om my Raspberry pi, i've got "NoCLassDefFoundExecption: SerialPortEventListener..!
I just don't know why, it won't find the library and use it..!
On my Pi i have librxtx-java installed and JDK-7-oracle-armhf.
librxtx-java should be setting its JAVA_PATH on it's own when installed, but not sure that is done correct!
(I've got a folder /usr/jni and it contains: librxtxSerial.so and
/usr/lib/jvm/jdk-7-oracle-armhf/).
Looking at the library Javax.RXTXcomm in Eclipse, i've got RXTXcomm.jar, that contains SerialPortEventListener, so it is defininated i the .jar.
I'm thinking about, could it be, that there is a missing link between my Java JVM and linux serialport driver? My JRE is working in some way, because it will execute a code to readout HOSTNAME & IP-Adress.
So is there some one who knows how to fix this..?
This is a readout of Java Exception:

A copy of my code. "SimpleRead.java" The original from java comm API samples
You have to change the reference from javax.comm to gnu.io in your source code.
Try following:
Switch to root and run the program you created
If that helps do following
sudo adduser username dialout
then log out and log in from all terminals and GUIs
I tried to execute CreateTextFileTest.class file with classpath in the terminal as the following:
java -classpath ..:"/home/fatih/NetBeansProjects/Unit17 - CreatingTextFile/src/unit17/unit17/creatingtextfile" CreateTextFileTest
My class files in this directory : /home/fatih/NetBeansProjects/Unit17 - CreatingTextFile/src/unit17/unit17/creatingtextfile .
I have 3 classes in the directory: AccountRecord.class , CreateTextFile.class, and CreateTextFileTest.class
But, when I executed the CreateTextFileTest from the terminal with the code above, an error occured like that:
Exception in thread "main" java.lang.NoClassDefFoundError: CreateTextFileTest (**wrong name**: unit17/creatingtextfile/CreateTextFileTest)

As far as I understand because CreateTextFileTest.java uses two different classes, executing fails. How to handle this situation? How to run my java project? How to use classpath in this situation? Am I using wrongly?
The error message states that the package name declared in your compiled class doesn't match what the JVM was expecting given your classpath setup. The classpath should point to the directory from which your packages start, not the directory actually containing your .class files. Given your error message I believe that this should work:
java -classpath ..:"/home/fatih/NetBeansProjects/Unit17 - CreatingTextFile/src/unit17" unit17.creatingtextfile.CreateTextFileTest
Given the duplicate unit17 in your path I get the impression there's something else mixed up here. You'll get a better answer on Stack Overflow...
I am trying to run a hadoop job on a server. The version is 0.20.2.
I have a big amount of jars, I am running:
hadoop jar GenData.jar -libjars /path/jar1,path/jar2,...
I am getting the error below even if the corresponding classes are inside the jars:

Looks like you are getting this exception from Hadoop client side, Mapreduce driver code execution happens in Client JVM. In hadoop -libjars is a generic option which is used for adding dependent jars to mapper/reducer. In your case for adding Jars to Client set you may set the following environment variable,before executing the hadoop command.
export HADOOP_CLASSPATH=<PATH_to_jar>/Jar1:<PATH_to_jar>/Jar2;
(colon ":" can be used for specifying more than 1 jars, In your case you may add the Jar that contains the class org.apache.avro.mapreduce.AvroKeyInputFormat).
New edits
Here first of all you need to find the jar containing the class org.apache.avro.mapreduce.AvroKeyInputFormat. You can find the class inside the jar avro-mapred*.jar (Get the compatible version of avro-mapred-version.jar from internet ) include the same in your classpath using the above command.
You are missing avro-mapred dependency.
I am using Eclipse with Eclipse Maven Plugin (m2e).
My java program compiles and run correctly from eclipse interface but I am unable to compile and run it from terminal.
My Eclipse Setting:
I am using two third party APIs, for which in eclipse build path I added
"/home/syed/workspace/FirstMaven/target/resources/fuse-jna-master/build/classes" (as external class folder)
"/home/syed/workspace/FirstMaven/target/resources/apache-jena-2.11.1/lib" (as external jars)
Package:
package org.organization.upesh.FirstMaven;
My Project path:

When I try to execute myProgram via below command
syed#ubuntu:~/workspace/FirstMaven/target/classes$ java org.organization.upesh.FirstMaven.myProgram
it gives me these errors:

But my test program that do not use the third party API runs correctly via:
syed#ubuntu:~/workspace/FirstMaven/target/classes$ java org.organization.upesh.FirstMaven.test
I think myProgram is not executing because of the two APIs (class folder and jar folder) that I am using.
I have added path of class and jar folders of the APIs to /etc/environment (given below) and rested my computer, but still the same error
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/syed/workspace/FirstMaven/target/resources/apache-jena-2.11.1/lib:/home/syed/workspace/FirstMaven/target/resources/fuse-jna-master/build/classes"
Please guide me how to run my program correctly
JVM does not get libraries from PATH. It uses special environment variable CLASSPATH that can contain a list of directories or jar files separated by colon on Unix or semicolon on Windows.
So, just define CLASSPATH and put references to all your libraries there.
Aleternatively (and IMHO better) use command line switch -classpath (or its alias -cp) when running java:
java -cp mylib1.jar:mylib2.jar com.mycompany.Main
I'm trying to run some applications (both my own and tutorial-applications) to help me understanding the basics of JMS. The code in the applications should be correct (for at least some). My added libraries are: Java EE 6 API Library - javaee-api-6.0.jar, jndi-properties.jar, appserv-rt.jar, javaee.jar and JDK 1.7(Default).
But with every single application I try to start, I get the following error message:

Exception in thread "main" Java Result: 1
BUILD SUCCESSFUL (total time: 1 second)
Note that it does say BUILD SUCCESSFUL, but it's a runnable form class (with 2 textfields and a button) and I don't see my form.
I'm trying my applications in NetBeans 7.1.1 using GlassFish Server 3.1.2 1. I've configured the used connection factories and destination resources in the admin console.
As seen by other related questions, I've tried moving the javaee.jar up and down the classpath, and even removed it, with no results. The same goes for Java EE 6 API Library, but that jar is needed for my project.
Changing the javaee-api-6.0.jar to javaee-api-5.0.5.jar fixed it.
