All the applications that we run work fine on Tomcat 7 - Tomcat 9 (after we modify context.xml). Most of our apps are pretty simple, but we do have a few with either complex calculations or complex REST APIs. Your challenges with Tomcat 9 should probably be taken up on the Tomcat mailing list (great place, BTW). If you go under Project->Properties->Run, what does the Java EE Version say? If you have a web.xml (most likely), what is the web-app version attribute value? Just looking at the drop-down menu for Java EE Version, it doesn't look like NetBeans supports anything lower than Java EE 5. If you have a really old web application running servlet spec 2.4, NetBeans 12 may not recognize it. In that case, you should be able to build your application in NetBeans 12, run Tomcat separately, and deploy using the manager application. Please note that if you use Maven and run NetBeans on Java 11, you'll need to configure a JDK 8 Java Platform (under tools). Technical debt is really dangerous. If there is a security issue with unsupported platforms, the resulting fire drill is unpleasant at best (speaking from personal work experiences).

Mark,

My project is old, and is running on tomcat7 in production. It seems mysql
was updated on the production server, and now I cannot add data to
mysql/the application because of this error message:

Generated keys not requested. You need to specify
Statement.RETURN_GENERATED_KEYS to Statement.executeUpdate(),
Statement.executeLargeUpdate() or Connection.prepareStatement().

I need to update the java files for db access, so I need netbeans to work
with this project so I can make a new .war file and update the production
server.

I realize that I am using old stuff, but it works and I don't have time
right now to upgrade the entire site (launched in 2000). I tried running
the site on tomcat 9 when it came out, and there were too many issues to
resolve at that time, so I left it on tomcat7.

I still think there is something screwy with netbeans if it will allow a
tomcat7 server to be added, and run, but won't associate it with a project.

Thanks,

Mark

Mark,

What servlet specification is your project? Tomcat 7 (which is EOL BTW)
will handle up to servlet specification 3.0 (J2EE 6 Web). Anything later
will require a later version of Tomcat. Tomcat 9 is probably the best
choice until you're ready to switch to the Jakarta namespace.

Mark,

I tried that. The problem is the server list in the project run

properties

isn't populated with my tomcat installation. There is nothing in the list
to select.

I have the latest netbeans on Ubuntu (at least it says it is up to

I still can't get the project to associate with Tomcat. I remove the

How

do I get out of this endless and unproductive loop?

Mark

Did you change the project run properties?
