问题 I want a file in my repository to be automatically updated (with any value, I just want its timestamp to be changed) with every git commit. How can I do this? My reason is to force my Glassfish appserver to reload my webapp when I build it on the server. I need to touch a file called .reload for this to happen. Rather than doing so manually, I want git pull origin; mvn build on my server to also touch the .reload file. 回答1: You could just use the Maven Antrun Plugin or the Groovy Maven Plugin

问题 As everyone knows jsp can't work with classes outside current osgi web archive bundle. This is a bug in GF. The developers of glassfish for workaround of this bug https://java.net/jira/browse/GLASSFISH-11208 offer to use offline jsp compiler (by other words to compile jsp files not during deployment time but during archive building time). Ok, and I used jspc-maven-plugin to compile my jsp during wab building. <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>jspc-maven-plugin<

问题 Similar to What to put into jta-data-source of persistence.xml? and How to map jpa datasources in WildFly? However, I am asking for something that would work on all vendors or at least WildFly, Glassfish/Payara, WebSphere Application Server classic, WebSphere Application Server Liberty, TomEE.

问题 I’ve come to an hold with my programing because I’m getting an error from glassfish. I’m using NetBeans IDE 7.3 for this project. And I’ve built a simple program which runs over the web(jsp file etc). But I keep on getting the weirdest error display from glassfish.
