[linwaterbin]

看下tomcat.log

[zjw3zjw]

修改catalina.bat的配置

[Wentasy]

修改JVM参数。

[sych888]

占个位置......

[川哥119]

按照网上的说法：在catalina.bat中添加了如下内容，但是还是不行 set JAVA_OPTS=%JAVA_OPTS% -server -Xms1024m -Xmx1024m -XX:MaxNewSize=256m eclipse的eclipse.ini参数也修改了,依然还是不行。 -vmargs -Dosgi.requiredJavaVersion=1.5 -Dhelp.lucene.tokenizer=standard -Xms512m -Xmx1024m

[Rotel-刘志东]

看一下tomcat日志文件报的什么错误。
