使用jsp:useBean的時候出錯！

JSBean
其他jsp頁面正常
有一個頁面是
<%@ page contentType="text/html"%>
<jsp:useBean id="test" scope="session" class="testBean"/>
<%=test.getUserid()%>
<%=test.getPassword()%>

類testBean程式碼為
public class testBean implements java.io.Serializable{
private String userid = "init";
private String password = "init";

public String getUserid() {
return userid;
}
public void setUserid(String userid) {
this.userid = userid;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
並且編譯透過

但是執行的時候報錯
HTTP Status 500 -

org.apache.jasper.JasperException: Unable to compile class for JSP

No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
If using an alternate Java compiler, please check its installation and access path.

note The full stack trace of the root cause is available in the Tomcat logs.


應該是找不到編譯所需的類包，但是所需要的類我都在CLASSPATH中宣告瞭啊
我的CLASSPATH是
.;%JAVA_HOME%\lib\tools.jar;%JAVA_HOME%\lib\msbase.jar;%JAVA_HOME%\lib\mssqlserver.jar;%JAVA_HOME%\lib\msutil.jar;%JAVA_HOME%\lib\msutil.jar;%JAVA_HOME%\lib\jbcl.jar;%JAVA_HOME%\lib\servlet-api.jar;%JAVA_HOME%\jre\lib\

我的JAVA_HOME是
c:\j2sdk1.4

請問哪出錯了，謝謝
