I just made a Gui builder project, designed a login form but whenever I try to build or compile, i get the below exception

The problematic line seems to be <generateGuiSources srcDir="src" encoding="UTF-8" guiDir="res/guibuilder" /> in the build.xml file.
I have tried both JDK 8 and 11, still same results. My Netbeans version is also 11. I have updated project files in the codenameone settings, refreshed libs but still got the same result. Any solution to this will be appreciated.

I have a program in Apache Flink. I tested and ran it on the local machine and every thing works fine. To run the program on a remote cluster, I did necessary changes as mentioned in Apache Flink Official Website.
I did the following changes:
The two points below
ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
ExecutionEnvironment env = ExecutionEnvironment.createRemoteEnvironment("taskManagerName",
portNo,paralelismNo);
Fixing the necessary paths to read input files and write outputs.
Generate a thin jar out of the program and put the necessary jar
libraries into a folder besides my project jar file called
myproj.jar.
copying the data and the jar library and myproj.jar into the cluster
and run the following command remotely on the cluster:
java -cp pathToJarLib \\* -jar myproj.jar
But, I get the below error and I don't have any clue to fix the issue. There are no relevant log files which can aid me in fixing this issue.

Your classpath is obviously not complete. Try to submit via bin/flink run myproj.jar. This sets up the classpath correctly.
I have a big application that worked perfect inside eclipse, I create an executable jar file for my application, My application use jython to define some resources. Also I create `the following .bat file to run the file:

When execute the .bat file an exception appeared, this is a part of this exception:

The vecmath.jar file and other external lib are founded inside a folder called externalLib which in the same folder of the Myprog23.jar and .bat files
How to solve the problem and what is need to be set?
You need to add all jars used in program to classpath. So, in your case all jars present in externalLib directory should be added in classpath.
For adding jars in classpath you may refer Setting multiple jars in java classpath
I am assuming that you have correctly set your CLASSPATH variable. Also assuming you have correctly installed JyThon. You should really make sure to TEST JyThon hello world OUTSIDE of your application environment as well. You need to take this step by step, Alice is a complex system, and so it is difficult to debug your issue without making sure basic structure of libraries is in place.
With these assumptions, you can proceed with JyThon documentation FAQ:
Jython cannot find your Java class, even though it exists in the class path.
Jython cannot find your Java class, even though it exists in the class
path. This shows up as "ImportError: cannot import name xxx" or
"AttributeError: java package xxx' has no attribute 'yyy'"
This happens when Jython is installed as a Java extension (i.e. when
jython.jar is installed in java\jre\lib\ext) and your classes are
installed in the classpath.
The reason is Java extensions can only see other extensions, not other
classes defined in the CLASSPATH or passed in to java using the
--classpath option.
There are two ways to fix this:
Move your classes to the java\jre\lib\ext directory.
Remove jython.jar from the java\jre\lib\ext directory and put
jython.jar in the CLASSPATH or use the java --classpath option.

I have kept Firefox to version 15 so that it is supported by Selenium Webdriver but suspect that the issue is to do with not able to read profile directory.
Your assistance would be very much apprecaited.
Many thanks,
George
The problem you are seeing has nothing to do with your Firefox profile.
Actually, it is the JVM classloader that complains that it can't find the com.google.common.collect.Maps class.
This usually means that you don't have Guava (which is a dependency for Selenium) on your classpath. Clean and rebuild your project, check your classpath, check the various versions of libraries that might be there. If you're using some kind of dependency management system (Maven, Ivy etc.), check it's configured right.
Import the .jar file to Eclipse downloaded from here (depending on the current version).
open this link https://www.seleniumhq.org/download/ and download Java 3.11.0(current version) open zip file to desktop on netbeans or eclips click add jars/file in selenium-java-3.11.0\libs select all file also in selenium-java-3.11.0 select client-combined-3.11.0.jar you will be ok. dont remember to add System.setProperty("webdriver.chrome.driver", "C:\\chromedriver.exe"); code. you can download chromedriver this link https://chromedriver.storage.googleapis.com/index.html?path=2.38/
In my case the Guava dependency was corrupt. Worked fine after I deleted the corrupt jars and rebuilt whole project.
Thank you for offerring your suggestion for a solution to this issue. I have found the exact answer from Selenium 2 WebDriver NoClassDefFoundErrorS which has resolved the underlying issue.
George
add below maven dependency and clean and compile your code.

Any help would be appreciated.
This exception is caused by compatibility issues between asm-4.0.jar and asm-3.1.jar. With the new Version of AppEngine, asm-4.0.jar is used and it is not compatible with Jersey, which relies on asm-3.1.jar. To make Jersey still work on GAE 1.7, you have to remove the dependency on asm-4.0.jar.
See this post : http://cloudvane.com/2012/09/23/problem-with-google-appengine-and-jersey-with-java/
It s tested and verified, like that:
add asm-3.3.1.jar to your war->lib
add it to you re build path
remove physically the asm-4.0.jar
Project -> Properties -> Google -> AppEngine: switch Datanuclueus to v1
That s it!
The instructions on this post took care of my problem.
Apparently the jersey-server 1.13 jar is compatible with asm3.1 and GAE 1.7.1 needs ASM 4.
Using the Jar repackaging tool jarjar you can deploy a asm 3.1 jar that will play with asm 4.
You may need to use JarJar version 1.3 if 1.4 gives an error message.
The new Jersey version 1.18.1 doens't depend on Asm 3, so it's compatible with GAE!
Maybe this will help: java.lang.IncompatibleClassChangeError: Implementing class Mongo
It's not exactly the same class, but the problem occurs when you have a library with 2 different version jars. Make sure you did not include any extra libraries or (I'll explain what happened to me):
You have A-1.0.jar and A-1.0.jar has inside another jar, let's say B-1.0.jar, but you have included separately a B-2.0.jar and in this way the two different version B jars are the problem.
Make sure you did not make this.
Same problem here, but I believe I've fixed it!
The trick was running a clean inside of eclipse, which notified me of the following error:

Apparently, GAE does not like having two versions of ASM loaded. On a whim, I went into the eclipse project properties and changed the datanucleus version from v2 to v1. I redeployed and now my app works. So much for catching these kinds of issues in the local dev environment . . .
I think I spent more time configuring GAE to run with jersey than I did actually writing the app. This may be my first and last GAE hosted app.
Did you update your App engine's SDK? (Recently the App engine SDK was updated from 1.7.0 to 1.7.1.)
Try to revert your app engine's SDK to 1.7.0. I have tried many solutions that I found on the Internet, none of them worked for me, but this one worked.
I have no idea how I can safely change my app engine project's sdk version for now. If anyone knows how to change the SDK version of the app, please let me know.
I got this error working on a maven project using Jersey-1.11 to develop a REST service:
cglib-3.0 depends on asm-4.0, and so I excluded it, leaving asm-3.0 to stand. This is because the Jersey version I am using uses asm-3.0.

I have tried lot, but cannot resolve the issue.
Please check this file: jasper-jdt.jar. If it doesn't exist in your /lib directory, than you should get one.
Probably means exactly what it says, you don't have a Java compiler. You need to install a SDK so that it can compile JSPs . Check for Java SDK and don't forget to set JAVA_HOME .
See this discussion for troubleshooting your problem.
