Some years ago I wrote an inventory application using the NetBeans platform modular framework. In the ensuing years it’s gone by the wayside. I haven’t programmed in Java for years now. I find it’s not like riding a bicycle. I have a renewed interest.
My application is in working order; Postgresql back-end, Swing front-end, its all humming away but I’d like to do a bit more with it so to re-familiarize myself with this environment I thought I would walk through the CRUD Tutorial at: https://netbeans.apache.org/tutorial/main/tutorials/nbm-crud/ <https://netbeans.apache.org/tutorial/main/tutorials/nbm-crud/> It’s old, written for Java 1.7 I think and for Netbeans I’m using: Product Version: Apache NetBeans IDE 9.0 (Build incubator-netbeans-release-334-on-20180708) Java: 9.0.4; OpenJDK 64-Bit Server VM 9.0.4+11 Runtime: OpenJDK Runtime Environment 9.0.4+11 System: Mac OS X version 10.16 running on x86_64; UTF-8; en_US (nb) EclipseLink (JPA 2.1) jar:nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/org.eclipse.persistence.core-2.5.2.jar!/ <nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/org.eclipse.persistence.core-2.5.2.jar!/> jar:nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/org.eclipse.persistence.asm-2.5.2.jar!/ <nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/org.eclipse.persistence.asm-2.5.2.jar!/> jar:nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/org.eclipse.persistence.antlr-2.5.2.jar!/ <nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/org.eclipse.persistence.antlr-2.5.2.jar!/> jar:nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/org.eclipse.persistence.jpa-2.5.2.jar!/ <nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/org.eclipse.persistence.jpa-2.5.2.jar!/> jar:nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/org.eclipse.persistence.jpa.jpql-2.5.2.jar!/ <nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/org.eclipse.persistence.jpa.jpql-2.5.2.jar!/> jar:nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/javax.persistence-2.1.0.jar!/ <nbinst://org.netbeans.modules.j2ee.eclipselink/modules/ext/eclipselink/javax.persistence-2.1.0.jar!/> … I’ve been through this every which way I can think of and it’s really bugging me I can’t get it going. I was hoping someone might be able to help me with the error I get when running the resulting DBManager application: [EL Info]: connection: 2024-11-07 12:57:10.479--ServerSession(647762109)--file:/.../DBManager/build/cluster/modules/ext/CustomerLibrary.jar_CustomerLibraryPU login successful [EL Warning]: metamodel: 2024-11-07 12:57:10.497--The collection of metamodel types is empty.
