linux 为什么我的eclipse里面没有java project

我安装tomcat运行时JRE——HOME不对，但进了8080了，提示成功安装配置，但页面就只有纯文字，不知到JAVA_HOME有没有配置成功。pyt@pyt-Ideapad-S205:/usr/share/tomcat7/bin$ sudo ./startup.sh
Using CATALINA_BASE:   /usr/share/tomcat7
Using CATALINA_HOME:   /usr/share/tomcat7
Using CATALINA_TMPDIR: /usr/share/tomcat7/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/share/tomcat7/bin/bootstrap.jar:
pyt@pyt-Ideapad-S205:/usr$ ps -ef|grep tomcat
tomcat7   5040     1  3 15:23 ?        00:01:25 /usr/lib/jvm/default-java/bin/java -Djava.util.logging.config.file=/var/lib/tomcat7/conf/logging.properties -Djava.awt.headless=true -Xmx128m -XX:+UseConcMarkSweepGC -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/share/tomcat7/endorsed -classpath /usr/share/tomcat7/bin/bootstrap.jar:/usr/share/tomcat7/bin/tomcat-juli.jar -Dcatalina.base=/var/lib/tomcat7 -Dcatalina.home=/usr/share/tomcat7 -Djava.io.tmpdir=/tmp/tomcat7-tomcat7-tmp org.apache.catalina.startup.Bootstrap start
pyt      10263  2210  0 16:03 pts/1    00:00:00 grep --color=auto tomcat
pyt@pyt-Ideapad-S205:/usr$ 
然后我安装进入eclipse但new project 里面没有java project ,只有简单的两项，新手，谢谢
