	export JAVA_HOME=/usr/local/jdk1.7.0_45
	export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

</pre><pre code_snippet_id="367718" snippet_file_name="blog_20140528_5_9233168" id="best-answer-content" class="reply-text mb10" name="code" style="white-space: pre-wrap; word-wrap: break-word; color: rgb(51, 51, 51); line-height: 22px; background-color: rgb(255, 252, 246); margin-top: 0px; margin-bottom: 10px; padding: 0px; font-family: Arial; zoom: 1;">4、使配置生效：
