New ObjectDB/JPA tutorials have been published today: Eclipse/JPA Web Application Tutorial NetBeans/JPA Web Application Tutorial The new tutorials demonstrate how to build a simple database driven web application using ObjectDB and JPA. Understanding these tutorials requires some familiarity

Am getting inconsistent results with the "objectdb.temp.no-enhancement-crc-check" system property of objectdb-2.6.9_02 in a Glassfish web app. Can see correct version of objectdb-2.6.9_02 in /build/ web / WEB -INF/lib. When one runs the enhancer (which I am doing post-compile, pre-deploy

Hello guys, I have a question about creating small new web application, I am almost done with researching and studying and I have covered all the important concepts e.g. # Starting from web technologies: HTML, CSS, JS, JQuery. # Moving to Java Technologies:  Core Java, Servlet, Managed Beans

ObjectDB: 2.7.1_06 [EDIT: Glassfish4.1.1 or Payara payara-4.1.2-174] I have been profiling a large web app with the NetBeans 8.2 Profiler. I can see that exactly one instance of each entity is present in memory, at web app startup, before I've loaded anything, and they won't garbage collect

I followed each and every step of NetBeans/JPA Web Application Tutorial but when i am trying to run the web application the following error is prompted on the run console: Start is in progress... start?path=/GuestBook FAIL - Application at context path /GuestBook could not be started C:\GuestBook
