Java Web Start support in Java 9 and beyond

2643536Oct 24 2017 — edited Oct 30 2018

I'm confused about the status of Java Web Start. On Oracle's Support Roadmap we can read this:

Support of Deployment Technology

The web deployment technology, consisting of the Java Plugin and Web Start technologies, has a shorter support lifecycle. For major releases through Java SE 8, Oracle provides five (5) years of Premier Support for these technologies. Extended Support is not available for the deployment stack, and will not be available for support beyond Java SE 9. See the Oracle Lifetime Support Policy for details.

Deployment Technology for Java SE 6 and Java SE 7 may be removed at any time after Jun 2017.  Although the deployment stack may be included in Java SE 9 or later releases, Java SE 8 is the recommended and only supported version of the deployment stack.

Now, we have known for quite some time that applets and the Java Plugin were to be removed in a future version of Java, but I had never read about Java Web Start being a candidate for removal.

In Oracle's Java Platform, Standard Edition Deployment Guide#Getting Started (a Java 9 documentation page), Java Web Start is advertised as an alternative to the deprecated applet technology:

Although available and supported in JDK 9, the Applet API and the Java Plug-in are marked as deprecated in preparation for removal in a future release. Alternatives for applets and embedded JavaFX applications include Java Web Start and self-contained applications.

Am I worrying for nothing or I have missed an announcement about the deprecation of Java Web Start?

The upgrade to a 2007+ file format?

XLS is a different format than XLSX.

They are both different than CSV.

Many times I have seen CSV files with the XLS/XLSX file extension.  This is wrong.  This is Sooo wrong.  Please ensure this is not the case.

I don't use the Data Load Wizard.  But I heard that it now supports the XLSX format.

XLS format should no longer be in use.  As such, I doubt the Data Load Wizard will ever support XLS format.

Workaround

Save the file as an XLSX file and try again.

File is XLSX.

Is it really an XLSX file? can you change the extension to ZIP and open it? (this question is a habit of mine.  I've seen too many people claim their CSV file is an XLSX file)

Does the XLSX file actually contain the correct worksheet name that the Data Load Service is looking for?

Is it spelled correctly?  (don't laugh - I once had someone misspell RAT)

Case matches? (I'm not sure if this is the case.  As I've said, I don't use Data Load Service)

Without trailing spaces?

What does the debug log say?

@Tomek,

File is XLSX sure? You can try again by changing the file extension. or Please re-edit the file and save it in the same format and try to upload and then upload the file.  I also had a similar problem once.

Found the solution...

By opening it in a special repair mode and saving it, I can then open it with Apex.

On Data Load Definition > Data Profile > Advanced found Default Sheet Name as sheet2.xml, changed to sheet1.xml and error disappear. I did never change that property to sheet2.xml.
