All,
I am getting the com.mysql.jdbc.Driver exception when trying to load the Driver class using Class.forName("com.mysql.jdbc.Driver"). I have written a custom Eclipse plugin and wanted to access the database in my custom Eclipse plugin.
I have tried following 2 options, both obviously failed:
1 > Adding the mysql connection JAR file to the Eclipse plugin build path
2 > Adding the connector JAR file as library and adding to the plugin's runtime classpath
Can anyone please help me out on this?
Here is the log:

I recommend to create your own OSGi-Bundle for the MySQL Driver, see http://wiki.eclipse.org/Create_and_Export_MySQL_JDBC_driver_bundle for a how-to. Afterwards you have to set a dependency in your plugin.xml of your bundle to the created mysql-bundle.
In addition: Please use in an OSGi environment not the DriverManager but an implementation of DataSource.

Below is the complete error message that Gephi gives me - when I try to upload a csv file.
I have java version: java version "1.8.0_221" and gephi version 0.9.2.
My java works very well,I set the environment variables and tested it.And I also configure the --jdkhome path settings as following
jdkhome="C:\Program Files\Java\jdk1.8.0_221" // in gephi.conf file.
But that didn't work for me.After that I've tried that right click on Gephi icon,choose properties,edit target as following
"C:\Program Files\Gephi-0.9.2\bin\gephi64.exe" --jdkhome "C:\Program Files\Java\jdk1.8.0_221"
I read that sentence also in Gephi.com "Java is bundled with the application so it doesn't have to be installed separately. On Windows and Linux, the system must be equipped with Java." what does it mean?
But that also didn't work. Any help will be appreciated !!
I've searched all of the internet generally people get the Error: " Java has not been found ".But this is not my problem mine is opening without any error. And then when I try to upload for example Nodes1.csv file it gives the following error.

I had a java version 1.8 both JDK and JRE in program files. I just removed java and just download JRE 1.8 runtime environment and it worked. And please pay attention that When multiple JRE or JDK are installed on the same machine, you can specify to Gephi to use a particular path. Edit gephi.conf as described in the upper section, uncomment the jdkhome line and set the JRE or JDK path.
I am using Win 7 and downloaded Junit 4.13 and hamcrest 2.1 from
https://github.com/junit-team/junit4/wiki/Download-and-Install
and put them in a folder named JUnit under C.
I have added the variable: JUNIT_HOME with value C:\JUnit.
I have also added the following to my classpath:
%classpath%;.;C:\Program Files\Java\jre1.8.0_171\bin;%CLASSPATH%;
%JUNIT_HOME%\junit-4.13-beta-1;.; %JUNIT_HOME%\hamcrest-core-2.1.jar;
Following https://github.com/junit-team/junit4/wiki/Getting-started,
I added the java files Calculator.java and CalculatorTest.java to my practice folder.
The command
javac -cp .;junit-4.13-beta-1.jar;hamcrest-core-2.1.jar CalculatorTest.java
is executed successfully. However, the command
java -cp .;junit-4.13-beta-1.jar;hamcrest-core-2.1.jar org.junit.runner.JUnitCore CalculatorTest
Fails, giving an error message like

Please note I have checked posts like java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing, but they have not been helpful. Could you please help?
The correct hamcrest jar is hamcrest-2.1.jar, not hamcrest-core-2.1.jar. You can download it from here.
According to mentioned guide it is assumed you have downloaded jars in the same package as your project:
Create a new folder junit-example and download the current
junit-4.XX.jar from JUnit's release page and Hamcrest to this folder.
If you decided to put jars separately probably you need to correct the command line correspondingly to take these jars files from %JUNIT_HOME%:
java -cp .;%JUNIT_HOME%\junit-4.13-beta-1.jar;%JUNIT_HOME%\hamcrest-core-2.1.jar org.junit.runner.JUnitCore CalculatorTest

I added all needed dependencies and it works - but - I dont think that this is correct behaviour.
Dependencies:
pegdown-1.1.0.jar
parboiled-core-1.0.2.jar
parboiled-java-1.0.2.jar
asm-all-3.3.1.jar
I have used eclipse Indigo and Juno to set up jalopy according to the jalopy installation guide.My Jalopy version is 1.9.4. I can format the code in Indigo without any problem. But I can't format the code
in Juno. In error log view, I can see Unhandled event loop exception in org.eclipse.ui plugin, when I try to format the code in Juno.

what is the reason for this exception? how to prevent this?
EDIT :same exception arise in Eclipse Kepler
The version you have is not compatible with Juno or Kepler. A more recent build fixes the problem.
