Since ArcGIS 10 supports java for desktop development too, I tried to set up a java add-in for ArcMap. Before writing my own add-in I had a go with one of the samples provided by the Java SDK, called "simpleaddin".
I can add the add-in to ArcMap without problems, and I can see it listed in the Add-In Manager.
Unfortunately, when I bring up the add-in toolbar (SampleJava Toolbar) in ArcMap, no custom commands are shown, just a bunch of labels saying "missing". Native ArcMap commands (like Fixed Zoom Out) are visible on the toolbar though (see attached image).
I also tried to create my own add-in, following the instructions given in this video:
Now, I notice that the name of your "class" is named "Button1". Did you create that class by clicking on the "class" hyperlink, or did you browse to the class named "Button1"?
After creating the add-in, I just pushed the "Add..." button to created a Button, and the class was already named Button1. Then, I clicked the "class" hyperlink, and accepted all the default values (just clicked "Finish").
I deleted the add-in cache, but that didn't change things either.
Do you know if there is any log file I could check? I enabled the "Create console..." option from the ArcGIS Java Configuration Tool, but no error messages are shown...
I don't think you'll see anything in the logs if your class is not loading.
This is the contents of my most recent log file:
INFO::Using the following arguments to create the JVM
-Djava.class.path=C:\Program Files (x86)\ArcGIS\Desktop10.0\\java\lib\arcobjects.jar

When you clicked the "class" hyperlink to create your Button 1 class, was it created in the right project? Just checking. I suspect that something is wrong with the way the Button 1 class was created.
This should be what a generic Button Class looks like, if you override/implement the init() method.
import java.io.IOException;
import com.esri.arcgis.addins.desktop.Button;
import com.esri.arcgis.framework.IApplication;
import com.esri.arcgis.interop.AutomationException;
public class Button1 extends Button {
/**
* Called when the button is clicked.
*
* @exception java.io.IOException if there are interop problems.
* @exception com.esri.arcgis.interop.AutomationException if the component throws an ArcObjects exception.
*/
@Override
public void onClick() throws IOException, AutomationException {
// TODO Auto-generated method stub
}
@Override
public void init(IApplication app) throws IOException, AutomationException {
// TODO Auto-generated method stub
super.init(app);
}
}
when I clicked the "class" hyperlink to create my "Button 1" class, the options on the dialog were the same as yours, and the class was created in the right project. But looking at your class code I noticed that my class was missing the init method (I should have checked that in the first place, my bad)!!!
Nevertheless, after adding the missing method, I still couldn't see my button in the Customize dialog. I checked the log files, and realized that I had set the wrong JDK version (1.7) in Eclipse when I created the add-in:
INFO::Successfully created an instance of : com/esri/arcgis/addinframework/AddInFactory
java.lang.reflect.InvocationTargetException

at java.lang.reflect.Method.invoke(Method.java:597)
Caused by: java.lang.UnsupportedClassVersionError: Button1 : Unsupported major.minor version 51.0
...
So I went back to Eclipse, compiled the project with the right JDK version (1.6), and finally the command was there!
Thanks a lot for your help, very appreciated Alberto
