环境配置问题

楼主hidejay（海带jay）2006-08-22 22:38:55 在 Java / Eclipse 提问

环境ＥＣＬＩＰＳＥ　３．２
ＭＹＥＣＬＩＰＳＥ　５．０
ＪＤＫ　５
ＴＯＭＣＡＴ　５．０

在ＭＹＥＣＬＩＰＳＥ中配置ＴＯＭＣＡＴ服务器，总会在配置的ＪＤＫ这里报错

to launch an application server,a full JDK(not just a JRE)must be specified.
if the selected JRE is actually part of a full JDK,please update its configuration to point to the JDK installation
root directory,not to its included jre subdirectory

郁闷中，为什么会找不到ＪＤＫ呢？问题点数：100、回复次数：15Top

会不会环境变量没有写好
claspath=C:\j2sdk1.4.2_04\lib\tools.jar;
JAVA_HOME=C:\j2sdk1.4.2_04;C:\Borland\JBuilder2005
path=%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\j2sdk1.4.2_04\bin;C:\Program Files\Microsoft SQL Server\80\Tools\BINN;c:\borland\JBuilder2005;Top

SERVLET问题
<servlet>
<description>This is the description of my J2EE component</description>
<display-name>This is the display name of my J2EE component</display-name>
<servlet-name>MyServlet</servlet-name>
<servlet-class>MyServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>MyServlet</servlet-name>
<url-pattern>/MtPack</url-pattern>
</servlet-mapping>

这个是XML下面的代码Top

你在添加tomcat服务的时候，打开jdk，重新命名一个jdk就可以了，不要它默认，选择你安装jdk的路径，一切搞定
