I created a Java project to automate simulations in COMSOL Multiphysics. However, whenever I try to run the code, I'm hit with the following error.

It looks like the compiler is looking for the libraries associated with the methods I'm using, which is weird because I added them to the project. Here's a photo of the project:

I feel like there's something really simple that I'm missing but I can't figure it out. Thanks

I installed Gephi 0.10.1 for Windows from https://gephi.org/users/download/, but the initialization of the Overview tab takes forever and I cannot view any graphs (including the test ones like Les Miserables.gexf). The little 'no entry' sign in the lower right corner says 'Unexpected Exception' and 'java.lang.reflect.InvocationTargetException'.

The solutions proposed e.g. here (https://github.com/gephi/gephi/issues/2189) did not work for me, nor did reinstalling Gephi. How can I solve this issue?
Building gephi following the tutorial from https://github.com/gephi/gephi/wiki/How-to-build-Gephi (rather than downloading it directly) solved the problem.
I am trying to automate BUILDS with anthill3 using remoting API but am getting an error when i try to get the Workflows from a project.
It seems the jar commons-graph.jar which is required to run this is not provided in anthill3-devkit.
As per the below link it says to download the JAr from anthill 5 , but i get an error when i try to download any fixes or release of anthill5 .
So if anybody has a resolution or the required JAR it will be very helpfull.

From your question its hard to understand why you are getting the error and why you might need JAR from a newer version of Anthill. From what I know, even sending you the JAR won't do the job because of the different versions. Please try to explain what is exactly you try and maybe we can find another way of doing it without using upper version
Anyway how can I send it to you ? E-mail ?
Thanks,

I have created a java application to connect to a MySQL database.
Once through the program install creator I created an .exe .
This executable runs, and the first form is login. When he tries to access the database to confirm the details of login gives this error.
java.lang.NullPointerException
Someone can help me solve this? The path is correct, because if run the .jar the application runs normally.
I apologize for the inconvenience.
Only have this to try explain better my question :S
I'm so sorry... I'm running a executable version from my java aplication.

You have an error in this class/line
jTMainMenu.java:786
Seems you tried to load a image in this point of your code, i don't know how you are generating a executable from your java code but this may be the source of the problem. Try to put this image outside of your executable/jar and use a relative path to load the image, like './my_image'.
You also have to take care if your user make a link to your executable, in this case a relative path can't resolve your problem. A simple way to solve this in java is get the source code location.
getClass().getProtectionDomain().getCodeSource().getLocation();
And use this location to find your image.
Please check the line number from the Stacktrace where you are getting the NullPointerException.
it is straight forward to find out the null pointer exception. Object is null or not initialize on which you are calling the method
try{
// add database connection statement here
}catch(Exception e){
e.printstacktrace();
}
// run the program from the command prompt.
// you can print the e.printstacktrace() on the popup as well to get the exception details
If you make a .jar, move that jar somewhere separate from the IDE (i.e. their classpaths), and start the jar, do you receive a NullPointerException?
This can be caused by resources, getResource, getResourceAsStreem, getBundle, as they are not case-sensitive in the Windows file system, but are case sensitive in a jar(and under Linux/MacOS).
(Also File cannot be used for jar resources.)
You might look in the jar with 7zip or so to inspect all paths.
I think it is not getting image icon in defined path
at javax.swing.ImageIcon.<init>(Unknown Source)
I have the following two guesses:
There is a problem with your path or classpath and loading the resource
The lines
at sensores.forms.jTMainMenu.initComponents(jTMainMenu.java:786)
at sensores.forms.jTMainMenu.(jTMainMenu.java:57)
indicate that something is initialized. Usually Swing/AWT uses multiple threads, so you might have a race condition here: The reference to the resource is handed to ImageIcon in your ìnitComponents method before another thread could set the value to something non-null. Try using proper synchronization/locking.
I have a java applet which uses a proxy service to a WCF Service to display data. The applet compiles and runs perfectly in Eclipse but when I build and export a Jar file then run it in a html page it fails with
java.lang.NoClassDefFoundError: javax/xml/rpc/ServiceException.
I have included jaxrpc.jar in my build path and my jar file contains all necessary classes.
The stack trace seems to be complaining about the line where I instantiate the proxy service from within the applet class. Does anyone know if there is an issue calling WCF service from a java applet?

This has been troubling me all day.
I think your issue is loading rpc jar, not call to wcf.
This post can be helpfull:
http://www.coderanch.com/t/259357/Applets/java/Applet-Axis-Client-Errors
It recomemds to sign your jar, verify you can access all your jars via browser, ensure you have all dependent.jars.
If all this will not help - i'd try to solve it as "
NoClassDefFoundError from spplet" issue.
Ok. I got this working by doing several things:
First I had to sign several of the jar files I was using:
jaxrpc.jar
axis.jar
commons-discovery-0.2.jar
but not:
javax.wsdl_1.6.2.v201012040545.jar
org.apache.commons.logging_1.0.4.v201101211617.jar
Secondly - all these files had to exist in the same directory as the html page, as I didn't specify a directory in codebase property for the applet tag.
Thirdly, within my main applet (ListProducts.class) I had to use AccessController.doPrivileged() around the code that first calls the proxy service:
EDIT: This step may not be necessary, as it now seems to work when I remove the doPrivileged block.
AccessController.doPrivileged(new PrivilegedAction() {
public Object run() {
try {
//instantiate proxy service and make rpc's
//do other stuff with results...
} catch (RemoteException e) {
// catch error
}
return null;
}
});
This combination of things got the java applet doing what it should. It was a painful slow process to discover which jar files were missing and then signing the appropriate ones.
I keep getting this error during runtime and I have no idea what is causing it. It believes there is a file missing?
Caused by: java.io.FileNotFoundException: C:\Program Files\Java\jdk1.7.0_07\lib\currency.data

I'm running my program with the JDK environment, I checked my jre7 folder and currency.data is present there! Why is it only present in the jre folder?
I got a similar error and this is just to help other people who may fall into the same trap :)
Error :
java.lang.InternalError: java.io.FileNotFoundException: null/lib/currency.data (No such file or directory)
This is because I set the global properties which turns out to be a very un-clever thing to do.
System.setProperties(new Properties());
The System properties are populated with very important data including:
path.separator
user.dir
file.encoding
file.separator
java.io.tmpdir
So basically don't do the above unless you know what you are doing.
If you want to a a property, do this instead:
System.getProperties().put("SOME_KEY", "SOME_VALUE");
or
Map myCustomMapOfProps = ...
System.getProperties().putAll(myCustomMapOfProps);
This is my solution.
You can add this in your code:
System.setProperty("java.home", "C:\\Program Files\\Java\\jdk1.8.0_60\\jre");
You must substitute the path of yours jdk version.
I had the same problem. It was caused by a Java verison conflict ("JAVA_HOME" was set to 1.7 and the property "-Djava.home" was set to 1.6).
I was using mvn to build the project and in the environment variable MAVEN_OPTS the option "java-home" was set to the WRONG value:
MAVEN_OPTS = -Xmx512m -XX:MaxPermSize=256m "-Djava.home=C:\Program Files\Java\jdk1.6.0_35\jre"
Just CORRECT it to:
MAVEN_OPTS = -Xmx512m -XX:MaxPermSize=256m
also check your other environment variables:
MAVEN_OPTS
JAVA_HOME
I found that currency.data is found in either:
C:\Program Files\Java\jdk1.7.0_17\jre\lib
or
C:\Program Files\Java\jdk1.7.0_07\lib
For some reason, when I execute my program, Java doesn't know to look one directory deeper.
In the old skool days, Sun specified that the JAVA_HOME should point to JDK_HOME/jre if a JDK was installed instead just the JRE.
This differentiation has slowly eroded for the same reason that 'exalator' is becoming an acceptable pronunciation for 'escalator': ubiquity.
At any rate some older apps still assume JAVA_HOME is the root of the JRE
JDK 1.7.0_43 does not have currency.data under lib/, only within jre/lib. That forces me to change the build scripts to use JDK for compiling and then to use JRE for unit tests. Unless there is a better way.
I had the same problem for a webapp deployed in wildfly 10 after installing a new jre while the server was running. Restarting the server resolved the problem.
