Re: Fwd: Can't get project to work with tomcat7
Mark, That helps a lot. I was able to manually start tomcat7, clean and build the site, and manually deploy the war file, trap the exception, change one line of code (add 33 characters), and the site works on my development machine. I now need to get a large bottle of bourbon, drink 1/2 of it for courage, deploy the new war file on my production server, and if it all works, then finish the bottle in celebrationif it breaks, then, well..., finish the bottle anyway... I am going to try to update the application to the latest standards (Java, JSP, Tomcat) and see how far I get. I have to admit, I left java quite a while ago for Python and the Django framework. I have thought of just keeping the db and rebuilding the site from scratch using Django...but that seems to be as large a project as updating the java site to the latest versions of everythingpass the bourbon!

Re: Can't get project to work with tomcat7
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.

Re: Can't get project to work with tomcat7
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.

Can't get project to work with tomcat7
I have the latest netbeans on Ubuntu (at least it says it is up to date). I open an old project, and it says the tomcat server is missing. I click on Resolve Missing Server, go through the steps to let netbeans know where my tomcat 7 server is located, and click finish. I end up back at the same place - "the target server has not been set or has been removed." If I go to the Services tab, click on Apache Tomcat, and then start, tomcat starts. I still can't get the project to associate with Tomcat. I remove the tomcat instance from Services, restart netbeans, and the same thing happens. How do I get out of this endless and unproductive loop? Mark
Issues with Netbeans Project Recognising Tomcat Installation
I am running Apache NetBeans IDE 11.2 with Java: 1.8.0_201 on Debian (Linux version 5.0.0-32-generic running on amd64). I have a tomcat 7.09 server installed and running. I can deploy war files from the tomcat manager app and I can see the tomcat log files in the Netbeans app. However, I cannot find a way to associate the tomcat server with my Netbeans project. Tomcat shows up in the list of servers, and I can start and stop it from Netbeans Services tab. The project says I am missing a server association, but when I click on Resolve Missing Server the resulting dialog does not have my tomcat 7 server listed. I have tried removing my tomcat installation from Netbeans and adding it from the Resolve Missing Server dialog, but I still cannot deploy directly from Netbeans because, you guessed it, I have a Missing Server Problem! I have also restarted Netbeans to no avail. I have fiddled with permissions for the tomcat7 installation to the point of chmod 755 for the whole directory (this is my development laptop and I only run instances locally), and that has not helped. Tomcat is installed in /var/lib/tomcat7. The user and group is tomcat7. Tomcat 7 should work with JDK 1.8, as it is certified for Java 6 and above. I also have issues with installing two tomcat servers - still can't deploy not does the project recognize any of them. I installed tomcat 9 in /var/lib/tomcat9 with user and group tomcat9. What I dream of is two tomcat instances, one tomcat 7 and the other tomcat 9, and the ability to deploy from Netbeans to test my project with both servers. How can I do that, or is that not possible? How do I get at least one server running so I can deploy from Netbeans? Thanks! Mark
