What's wrong with Http server of SunONE AS 7?

Question

I try to output something of database to a PDF file using jasperreports-0.5.2.jar and jsp file likes:
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@**:1521:**","**","**");
File reportFile = new File(application.getRealPath("test/iteminfo.jasper"));
//向报表中定义的参数赋值
Map parameters = new HashMap();
Integer i=new Integer(8);
parameters.put("pjId", i);
byte[] bytes =
JasperRunManager.runReportToPdf(
reportFile.getPath(),
parameters,
conn
The all relation jar have been included in CLASSPATH.
It work right if it's deployed in iWS6. But when I deployed it in docroot of SunONE Appliction server 7 U3 , it failed and said:
javax.servlet.ServletException: Error loading expression class : Test2
     at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:471)
     at jasper.test_jsp._jspService(_test_jsp.java:119)
     at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107)
----- Root Cause -----
java.security.AccessControlException: access denied (java.lang.RuntimePermission createClassLoader)
     at java.security.AccessControlContext.checkPermission(AccessControlContext.java:270)
     at java.security.AccessController.checkPermission(AccessController.java:401)
     at java.lang.SecurityManager.checkPermission(SecurityManager.java:542)
It seems something wrong with java security (Test2 is a middle file compiled by jasper and it's work right in command line.).
Who know why? Thanks.

Hi,
I added those two lines to my Sun Application Server 8.2 and it would not start...
Looking at the server.log I found:

I know you were suggesting it for version 7, but I have the same problem and wanted to give it a try... bad luck...
Does anyone could alaborate on the second method proposed above?

Eli.
