i think i can give you an explanation. weblogic runs under restrictive security environment. this prevents one of the pre-java 1.4 reflection bug workarounds from working. what you can see should be just a warning (rather than an error).
digester should still run fine after this warning but if you're running java 1.3 and things break when you run in weblogic, then you might need to upgrade since the reflection code in java 1.4 has far fewer bugs in.
unfortunately, the last release of beanutils repeats the warning message every time. you'd be well advised to upgrade to a recent nightly build - or CVS HEAD - of beanutils since this will only issue the warning once.

hi all,
i have downloaded digester 1.3 and i would like to use
it inside my application in weblogic 5.1.
i have written following XML file
<?xml version="1.0"?>
<myServices>
<serviceGroup name="My Personal Data">
<service name="Current Position">
<joltservice>
<jolt name="Current1" isHB="true"/>
<jolt name="Current2" isHB="true"/>
</joltservice>
<configtool>
<config name="CurrentPos"/>
<config name="DateSpec"/>
</configtool>
<field name="ADDRESS_CONAME"/>
<field name="ADDRESS_NAMEOFCOUNTRY"/>
<field name="ADDRESS_EMPLOYEENO"/>
</service>
</serviceGroup>
</myServices
for this XML file, i have written following classes part
of the com.xml package
- MyServices
- ServiceGroup
- Service
- JoltService
- Jolt
- ConfigTool
- Config
- Field
i am using this simple class for getting servicegroups/fields etc
based on rules
public class DigesterTest {
private Digester digester;
private String configFile;
public DigesterTest(String fileName) {
digester = new Digester();
digester.setValidating(false);
setRules(digester);
configFile = fileName;
}
/**
* Set the rules to be used to parse
* the XML file.
*/
private void setRules(Digester digester) {
/** Whenever we need to change rules, we must
* edit following section.
*/
// Adding rules to be used when <myService> element is encountered.
digester.addObjectCreate( "myServices", MyServices.class );
// Adding rules to be used when <serviceGroup> element is encountered.
digester.addObjectCreate( "myServices/serviceGroup", ServiceGroup.
class );
digester.addSetProperties( "myServices/serviceGroup", "name", "name" );
digester.addSetNext("myServices/serviceGroup", "addServiceGroup" );
// Adding rules to be used when <service> element is encountered.
digester.addObjectCreate("myServices/serviceGroup/service", Service.class);
digester.addSetProperties("myServices/serviceGroup/service","name"
, "name");
digester.addSetNext("myServices/serviceGroup/service" , "addService");
}
/**
* @return all services available in the
* configuration file.
*/
public MyServices getAllServices() throws Exception {
MyServices mp = (MyServices)digester.parse("myProfile.xml");
return mp;
}
but when i run this program in a servlet under weblogic 5.1 i got following exception
