挂毯+ JDO + GAE

我试着在GAE上运行Tapestry。过了一段时间，我能够解决最后的错误，至少显示一个简单的页面。但是，说实话，某种数据存储会很好。我试图使用tapestry-jdo，但是有我的问题：我无法使用JDO的任何部分，并且我已经尝试了几天。挂毯+ JDO + GAE

我会发布我的pom.xml文件，我已经工作了。我尝试了很多版本号的组合，但主要是测试JDO的actionlink失败，因为找不到org.datanucleus.store.appengine.jdo.DatastoreJDOPersistenceManagerFactory。剩下的时间，我从tapestry得到一个未捕获的异常，这是由另一个缺少的JDO类引起的，但是这次不是在构建JDOEntityManagerSource的时候，而是在更深的地方。

我没有学过编程，我自己教过，所以我的知识面很有限。此pom.xml可能包含针头条目。

如果我用maven构建它，在某些情况下我得到Could not transfer metadata asm:asm/maven-metadata.xml from/to local.repository (file:../../local.repository/trunk): No connector available to access repository local.repository。

的DataNucleus将-的AppEngine插件V2应该通过DataNucleus罐V3.0使用。*与javax.jdo JDO-API V3.0.1 ......在 http://code.google.com/p/datanucleus-appengine/wiki/UpgradingToVersionTwo

按照该文档为GAE

我想这就是解决方法，虐待它尽快尝试。你的链接说我应该使用org.datanucleus.api.jdo.JDOPersistenceManagerFactory，但官方文档仍然包含org.datanucleus.store.appengine.jdo.DatastoreJDOPersistenceManagerFactory – Quurks 2012-03-11 12:41:49
