要查看tomcat目前用的jdk版本 进入tomcat安装文件夹的bin目录下 执行./version.sh 就可以看到了,查看如下:
Using CATALINA_BASE: /usr/java/apache-tomcat-7.0.41 Using CATALINA_HOME: /usr/java/apache-tomcat-7.0.41 Using CATALINA_TMPDIR: /usr/java/apache-tomcat-7.0.41/temp Using JRE_HOME: /usr/java/jdk1.7.0_80 Using CLASSPATH: /usr/java/apache-tomcat-7.0.41/bin/bootstrap.jar:/usr/java/apache-tomcat-7.0.41/bin/tomcat-juli.jar Server version: Apache Tomcat/7.0.41 Server built: Jun 6 2013 11:16:08 Server number: 7.0.41.0 OS Name: Linux OS Version: 2.6.32-279.el6.x86_64 Architecture: amd64 JVM Version: 1.7.0_80-b15 JVM Vendor: Oracle Corporation
单独查看jdk版本(前提是写进了/usr/bin)
java -version
