tomcat启动报错

公司用的tomcat6.0.26，而家里的版本是6.0.18，程序部署过来之后启动时显示如下错误信息

信息: Not binding factory to JNDI, no JNDI name configured

2011-8-21 18:56:28 org.apache.catalina.core.StandardContext start

严重: Error listenerStart

2011-8-21 18:56:28 org.apache.catalina.core.StandardContext start

严重:

log4j:ERROR LogMananger.repositorySelector was null likely due to error in class

 reloading, using NOPLoggerRepository.

2011-8-21 18:56:35 org.apache.coyote.http11.Http11Protocol start

信息: Starting Coyote HTTP/1.1 on http-8080

第一个问题：log4j:ERROR这里，问题原因和解决方法如下：

The reason for the error is a new listener in Tomcat 6.0.24. You can fix this error by adding this line:

org.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false

to the "conf/catalina.properties" file in your tomcat directory.

第二个问题：Context [] startup failed due to previous errors，这里看不出具体的错误，查看tomcat的logs目录下的localhost.xxxx-xx-xx.log文件发现如下问题：

2011-8-21 18:59:38 org.apache.catalina.core.StandardContext listenerStart

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

java.lang.OutOfMemoryError: Java heap space

错误很明显，需要的就是增大相关jvm内存：

在bin目录下的catalina.bat中增加下面内容：

set JAVA_OPTS=%JAVA_OPTS% -server -Xms512m -Xmx768m -XX:MaxNewSize=768m
