java项目安装注意事项

安装注意事项：

1、所有的jdk和tomcat版本保持一致

2、检查library java包是否正确导入

3、编码格式为UTF-8

4、如果eclipse反应过慢可将eclipse下面的eclipse.ini文件改为以下内容，对eclipse进行优化。

-startup

plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar

--launcher.library

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20140603-1326

-product

org.eclipse.epp.package.jee.product

--launcher.defaultAction

openFile

--launcher.XXMaxPermSize

256M

-showsplash

org.eclipse.platform

--launcher.XXMaxPermSize

256m

--launcher.defaultAction

openFile

--launcher.appendVmargs

-vmargs

-Dosgi.requiredJavaVersion=1.6

-Xms40m

-Xmx512m

 

5、若报一下错误证明tomcat版本不对，换一个32位的tomcat

java.lang.UnsatisfiedLinkError:

D:\apache-tomcat-7.0.65\bin\tcnative-1.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

 

java.lang.UnsatisfiedLinkError: D:\duowan\apache-tomcat-7.0.65\bin\tcnative-1.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

 

6、Tomacat7启动报错如下：

解决方法为：在Tomacat7的context.xml文件里的<Context>中加上<Loader delegate="true" />

路径为：apache-tomcat-7.0.65\conf

更改以下位置：

<Context>

 

    <!-- Default set of monitored resources -->

    <WatchedResource>WEB-INF/web.xml</WatchedResource>

<Loader delegate="true" />
