Question

使用

运行Java EE应用程序

GlassFish Server 4.1 / Java EE 7
具有JPA 2.1的EclipseLink 2.6.0
Mojarra 2.3.0-m02
PrimeFaces 5.2 final
OmniFaces 2.1 final
MySQL 5.6.11
JDK 8u45

在重新部署应用程序时，偶尔会发生java.lang.NullPointerException抛出，但不会对应用程序造成任何损害。

它来自哪里以及为什么？我没有这个例外背后的原因，也没有申请似乎负责。

我遇到了这个问题，直到我创建了一个专门用于运行GF的新用户并安装了最新版本的JDK 1.8（我正在运行linux作为我的操作系统）

我创建了一个用户：gfadmin

创建新用户：useradd -d /home/gfadmin -g staff -s /bin/bash gfadmin

然后从oracle下载了JDK 1.8.0_91： （获取适用于您的操作系统和硬件的tar.gz文件） http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

将tar.gz文件放在/home/gfadmin

中

gunzip并取消tar文件。它应该创建一个目录：

/home/gfadmin/jdk1.8.0_91

编辑gfadmin用户.bash_profile文件并添加以下三行：

JAVA_HOME="/home/gfadmin/jdk1.8.0_91"
PATH="$JAVA_HOME/bin:$PATH"
export JAVA_HOME PATH

来源.bash_profile：

. ./.bash_profile

确认您使用的是刚刚安装的java版本，1.8.0_91：

java -version

在GlassFish Server上运行Java EE应用程序时偶尔会出现java.lang.NullPointerException
