My program is created using Netbeans and I need to make a .exe to make a setup file using innosetup, so I used exe4j to make the exe. This is what generates in a text file when all the steps are done.

Thank you.
Verify that org.netbeans.lib.awtextra.AbsoluteLayout is available in the classpath at runtime. You can locate AbsoluteLayout.jar in the NetBeans distribution, as shown below:
$ find . -name \*AbsoluteLayout\*
./Contents/Resources/NetBeans/java/modules/ext/AbsoluteLayout.jar
./Contents/Resources/NetBeans/java/sources/org/netbeans/lib/awtextra/AbsoluteLayout.java

I try to run the .jar file with double click but it won't open...
I suspect your issue is caused by not including images in your JAR. Please see this question on how to do that: It may be that you don't include images as resources in your JAR. See this question: Add image to JAR Java

Noclassdeffound error is thrown when the Java Virtual Machine (JVM) or an instance of the ClassLoader class tries to load the definition of a class, but the definition could not be found.where a class has a dependency on some other class and that class is not accessible.
In short at if you have used any external jar file than that jar file will be required at compile time as well at Run-time also in your case it seems that JVM is unable to find external jar file that contains WebcamPanel class at run time. so you need to pack that Jar file also with your application's Jar file.
for how to add External Jar file in your project you can refer

It worked two days ago. Now it doesn't. I'm 100% sure the coding is correct. This is the way I used to connect the database. Couldn't find an answer yet to my problem. Please give me an answer as i'm a beginner for java language. (Using jdk 7u72)
public void set()
{
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String su=new String("jdbc:odbc:MOVIESURF"); //This is the database
con=DriverManager.getConnection(su,"","");
st=con.createStatement();
}
catch(Exception e2){System.out.println(e2);}

Based on the comments, your system is now running on the Java 8 JRE. The ODBC Bridge has been removed from this, and all future versions. You need to find a native JDBC driver for the database you want to connect to, and put that on your classpath.
java -classpath "[/path/to/your/driver.jar];." [yourclassname]
Alternatively, you could explicitly use the JDK 7 runtime, but I'd recommend against this. You've uncovered a compatibility problem, and it's better to solve it than to try to work around it.
Please add your jar to the class path like below.
java -cp .;C:\Program Files\MySQL\mysql-connector-java-5.1.15\mysql-connector-java-5.1.15.jar MysqlConnect
Note:Please replace msql connector with your jar file as per requirement.
I have been trying to get a slick application to work on a website for awhile now, and I have the HTML code correct, I know that for sure, however I am getting an error from the applet saying this:

Done loading
I understand that the applet won't start. I've done some excessive searching to find the answer, however, I have found none. I do not use a GameState, but use a BasicGame. Most tutorials I've read say to just write it like a normal application. So I'm confused as to how to get this to work properly. It doesn't seem like I need to make any new changes, but that I can't figure out what exactly I need to do.
Any help would be appreciated.
Thank you!
It seems as if the error happened as a naming issue.
