tomcat7無法運行JPA

我正在使用JSF（使用JSF Majorra 2.1.6）和JPA（使用EclipseLink Juno的庫）和Tomcat 7服務器的Java EE應用程序。問題是，當我一個JPA應用程序添加到tomcat，Tomcat的運行失敗，我必須在控制檯的末尾以下信息：tomcat7無法運行JPA

這應該回答你：http://stackoverflow.com/questions/88235/dealing-with-java-lang-outofmemoryerror-permgen-space-error – szegedi

另外，你可以重新格式化你的代碼嗎？ –

看起來你正在耗盡內存。

您需要增加堆或燙髮大小。
