在weblogic使用javabean错误

我用的是jbuilder9,tomcat4.0,weblogic7.0

如下代码在tomcat中没有任何问题，但在weblogic中却问题很多

<%@ page contentType="text/html; charset=GBK" %>
<jsp:useBean id="bean" scope="session" class="com.wsg.dbase.bean" />

<html>
<head>
<title>
index
</title>
</head>
<body bgcolor="#ffffff">
<h1>
JBuilder Generated JSPaaaaaaaaaaaaaaaaaaaaaaaaaaaa<br>
aaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
</h1>
</body>
</html>

以上代码在weblogic中编译出错，信息如下：

C:\bea\jdk131_03\bin\java -classpath "C:\bea\weblogic700\server\lib\weblogic.jar;
C:\bea\weblogic700\server\lib\webservices.jar;E:\JBuilder9\lib\jdsremote.jar;
E:\JBuilder9\lib\webserverglue.jar;E:\javaxx\wlf\classes;
C:\bea\weblogic700\server\lib\weblogic.jar;C:\bea\weblogic700\server\lib\webservices.jar;

C:\bea\jdk131_03\jre\lib\rt.jar;C:\bea\jdk131_03\jre\lib\sunrsasign.jar;
C:\bea\jdk131_03\lib\dt.jar;C:\bea\jdk131_03\lib\htmlconverter.jar;
C:\bea\jdk131_03\lib\tools.jar" weblogic.jspc -d "E:/javaxx/wlf/classes/Temporary_Files/
.jsp/webf" -docroot "E:/javaxx/wlf/webf" -keepgenerated -compilerclass
com.borland.jbuilder.webserverglue.weblogic.jsp.NadaJavac "E:/javaxx/wlf/webf/index.jsp"

"index.jsp": java.lang.UnsupportedClassVersionError: com/wsg/dbase/bean (Unsupported major.minor version 48.0)
Exception in thread "main"

把以上代码改为如下：
<%@ page contentType="text/html; charset=GBK" %>
<%@ page import="com.wsg.dbase.bean"%>
<%!
bean b=new bean();
%>
<html>
<head>
<title>
index
</title>
</head>
<body bgcolor="#ffffff">
<h1>
JBuilder Generated JSPaaaaaaaaaaaaaaaaaaaaaaaaaaaa<br>
aaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
</h1>
</body>
</html>

在weblogic中编译，部署成功，但ie浏览的结果为：
