Controlling Access to Classes

Hi,
I know that you can use the keywords private and protected for methods and variables, but can you also use these keywords at the class level? I understand that the public modifier enables a class to be accessed outside of its package, and that if no modifier is used, then the class can be accessed by any class within the same package. But what would the private and protected keywords mean at the class level?
Thx.

It's can be explained.
private modifer forbid(? a don't know how to translate :) ) access to class, why you must need class that you can't access?
protected modifer used when you inheritr something/ but tou newer inherite class. You inherit it'as member.
It was simple question :)

Class not Found when accessing Proxy class from backing bean in VC.

Hi All,
I'm attempting to access a class of a webservice(generated as a proxy) within my ADF application and invoke the method within a backing bean of the View Controller(bean scope : backing bean). The proxy has generated an ObjectFactory class among other classes. When I access this Object factory class from within the backing bean, the application throws a Class not found error.
I don't know where the error lies since I've declared the View Controller of the ADF application dependent on the Proxy and I've imported the class and accessing it within a backing bean. How would you suggest I approach resolveing this.
JDev : 1.1.1.4
Thank you.
Regards
PP.

Hello Arun,
Thank you for suggesting a Data control, but my requirement isn't to drag and drop the method as a button. It's more of a behind the scnes updating data via a database adapter requirement.
I've resolved the issue. turns out, my deployment archive didn't include the proxy.jpr. Once included it works likea charm.
Thanks
PP.

Accessing Java Classes from Forms

Is is possible to access a Java class from Forms? I have been
creating an Active X control that returns a Java object, and from
that I can call methods on that object, but I would really like
to do that without having and Active X control in the mix. Any
suggestions?

Problem with Dynamically accessing EJB Class objects in WL 7.0 SP1

I am trying to build a component which has the ability to instantiate and execute
an known EJB method on the fly.
I have managed to build the component but when I try and execute it I get a ClassNotFoundException.
I know that the EJB I am trying to invoke is deployed and available on the server,
as I can see it in the console, I also seen to have been able to get the remote
interface of the object, my problem occurs when I try and access the class object
so I can perform a create on the object and then execute my method
The code I have written is below:
private Object getRemoteObject(Context pCtx, String pJNDIName, String pHomeBean)
throws Exception {
 String homeCreate = "create";
 Class []homeCreateParam = { };
 Object []homeCreateParamValues = {};
try {
//This call seems to work and doesn't throw an exception
Object home = pCtx.lookup(pJNDIName);
//However this call throws a java.lang.ClassNotFoundException
Class homeBean = Class.forName(pHomeBean);
Method homeCreateMethod = homeBean.getMethod(homeCreate,homeCreateParam);
return homeCreateMethod.invoke(home, homeCreateParamValues);
} catch (NamingException ne) {
logStandardErrorMessage("The client was unable to lookup the EJBHome.
Please make sure ");
logStandardErrorMessage("that you have deployed the ejb with the JNDI
name "+pJNDIName+" on the WebLogic server ");
throw ne;
} catch (Exception e) {
logStandardErrorMessage(e.toString());
throw e;
Any advice would be really appreciated, I'm fast running out of ideas, I suspect
it has something to do with the class loader but I'm not sure how to resolve it

Hello Joanne,
Congratulations! I'm very happy that you've managed to fix your problem. It's
always essential to understand how to package applications when deploying on BEA
WebLogic. Usually, by throwing everything into an EAR file solves just about all
the class loader problems. :-) Let us know if you have any further problems that
we can assist you with.

The class loader was the culprit which is what I suspected all along.
As soon

away!!!!!

Hello Joanne,
As Mr. Woollen mentioned, I also believe it's a problem with the class
loader.
You need to be careful how you arrange your EJBs, because WebLogic has
a specific
method in which it loads classes in an EAR, JAR, and WAR file(s). Please
refer
to http://dev2dev.bea.com/articles/musser.jsp for more information about
BEA WebLogic
class loading mechanisms and caveats. Also, try printing out the various
methods
that are available on the object that was returned to you via reflection.
For
example, use the getMethods() method, which returns an array of Method
objects
that you can subsequently cycle through and print out the various method
names.
This way you can discover if the class found/returned to you is indeed
the one
you intend to locate.
Hope this helps,

I believe the issue is the home interface class for this EJB is not

If you do:
getClass().getClassLoader().loadClass(homeInterfaceClassName)
I suspect it will fail. Reflection still requires that the class be
loadable.

Your code should look like

Are the EJBs that you are trying to access accessible via your
system
classpath?
Try to avoid having them accessible via the main system classpath,and
only bundle
them in your appropriate EJB jar files (contained in an EAR file,for
example).Maybe I should have laid the problem out a little clearer.
I have a number of EJB's bundled up in a JAR file which is hot deployedto
the
server. Within this first JAR file is an EJB (SSB) component that
needs
to
be
able to invoke a known method on another EJB. This second EJB may
or
may
not be
within the first JAR file but it also will be hot deployed.
The component trying to invoke the method on the 2nd EJB has to
be
able to
create
an instance of the 2nd EJB without actually knowing anything bar
a
JNDI
Name which
is passed in at runtime.
I can get as far as doing the
Object home = pCtx.lookup(pJNDIName);
This returned a class with the name
"com.csc.edc.projects.allders.httppostoffice.postman.PostmanBean_mp8qy2_Home
Impl_WLStub"
My problem seems to occur when I try and invoke the create method
Method homeCreate = home.getClass().getMethod("create", new Class[0]);
My code throws a java.lang.NoSuchMethodException at this point so
I
am
unable
to progress to the next step of :
Object bean = homeCreate.invoke(home, null);
So I can return the instantiated bean back to the calling client.
Why am I getting the NoSuchMethodException, is is because I am gettinga
stub
back rather than the home interface and if so how do I get the truehome
interface
from the bean
Thanks in advance

How to access a class file outside the package?

created a two java files Counter.java and TestCounter.java as shown below:
public class Counter
     public void print()
          System.out.println("counter");
package foo;
public class TestCounter
     public static void main(String args[])
          Counter c = new Counter();
          c.print();
Both these files are stored under "D:\Test". I first compiled Counter.java and got Counter.class which resides in folder "D:\Test"
when i compile TestCounter.java i got the following error message:
D:\Test>javac -classpath "d:\Test" -d "d:\Test" TestCounter.java
TestCounter.java:6: cannot find symbol
symbol : class Counter
location: class foo.TestCounter
Counter c = new Counter();
^
TestCounter.java:6: cannot find symbol
symbol : class Counter
location: class foo.TestCounter
Counter c = new Counter();
^
2 errors
what could be the problem. Is it possible to access a class file outside the package?

ya that's fine..if we have two java files where both resides in the same package works fine or two java files which donot have a package statement also works fine. But my doubt is, i have a Counter.class which does not reside in a package and i have a TestCounter.class which resides in a package "foo", in such a scenario, how do i tell to the compiler that "Counter.class resides in such a path, please look at that and give me TestCounter.class". i cannot use import statement to import Counter.class in TestCounter.java because i donot have a package for Counter.java.

How can I access another class in a MembershipRule's Expression

Hello,
I want to create an InstanceGroup using Module Microsoft.SystemCenter.GroupPopulator.
I need to collect all Logical Disks which contain an MS SQL DB Log File.
I would start as follows:

<GroupInstanceId>$Target/Id$</GroupInstanceId>
<MembershipRules>
 <MembershipRule>

<Expression>
 <And>
 
 <Expression>
 <SimpleExpression>
 <ValueExpression>
 <Property>$MPElement[Name="Windows!Microsoft.Windows.LogicalDevice"]/Name$</Property>
 </ValueExpression>
 <Operator>Equal</Operator>

In the first expression you "see" my question:
I want to compare the LogicalDisk's Name Property with the DB Log File's Drive property.
But how can I access the DB Log File's Drive property in this MembershipRule ?
Furthermore LogicalDisk and DB Log File must be hosted on the same Windows Computer.
Would be great if somebody could help.
Thanks
Sebastian

Hi Niki,
thanks for the idea, but that will not work. $Target/Id$ refers always to the group to be discovered.
On last week end I was given following idea, hope it will work:
Step 1
Collect all the DB SQL Logfile Objects and write computername (PrincipalName?) and Driveletter into a textfile, line by line. Shouldn't be a problem, PowerShell is your friend.
Step 2
Read the file from Step 1, build discovery data for each disk drive as object of class "Logical Disk (Server)",
and then discover the containment-relationships from those Logical Drive(Server) Objects to the InstanceGroup.
Perhaps I must do it for the OS-Version related Disks, because I need the target classes of the Logical Disk Freespace monitors. Some more work. "Risks": I donot know the discovery algorithm for the Logical Disk(Server) Objects, but a "deep
dive" into the MPs should help.
Thanks to all, who have read.
I will inform you about progress and success

Load Jar and access a class in jar at run time

Error Message : ClassCastExcption : jartest1 cannot be cast to ThingPresumably we can only hope that that is a transciption error. It always helps to use copy and past actual errors and code rather than manually typing them.

The interface class and plugable class must not be in the same jar.
A plugable interface requires two components
- Interface (generic sense)
- Functional components.
The Interface must be independant (own jar) so that it is available to the framework (user of plugin) and to the functional components. And the plugable component must not be on the java class path.
This also means that we know for certain that the plugable component is also on the system class path. That is a bad idea as well.
Given that it is pretty pointless to even speculate as to why this error is showing up. Create the correct jar layout. Test using the command line. Then test using servlets. Insure that the plugable jar is NOT on the java classpath for both tests.

Control Access in Message Monitoring

Can I control access to payload within PI-Message-Monitoring? The topic has been discussed already: How to Control Access To Payload
By using the "S_XMB_MONI-authorization-object" I can protect access to payload for certain messages, regardless of viewing it with Transcation "SXMB_MONI" or with "RuntimeWorkbench";
For me it is not clear, whether the "S_XMB_MONI-authorization-object" does only affect messages within the Integration-Server, or does it also work for messages in adapter-engine-message-monitoring? I mean, when using "Runtime-Workbench --> Message-Monitoring --> AdapterEngine..."?
Regards, Josef

Hi,
It works only for SXMB_MONI (ABAP stack), user on adapter engine can still see payload.
One hint I can give you to explore further, authorization on RWB are controlled by Visual Admin, you can explore something there to block user to view payload on RWB.
I am exploring it and will update you.

Accessing Java Classes from Webservice Stubs

So far I have been able to call a web service and copy the appropriate directories and files to the designated class path. I can also successfully access a class file like this:
MyObject = CreateObject("java", "ca.x.y.z.TestCollection.TestItem");
However, whenever I try to do something with that variable, I get a white screen. Any text that should have appeared before the command, will appear, but nothing appears afterwards, not even debugging info. Here are a couple of commands that will cause this to happen.
<cfdump var = "#MyObject#">
MyObject = CreateObject("java", "ca.x.y.z.TestCollection.TestItem").init();
x = MyObject.init();
Anybody have any ideas?

Ah, nothing like a fresh set of eyes to remind of the fundamentals. Thank you for that.
I actually could create a normal error by calling a method incorrectly. I would see the grey box and my debgging info would appear. However, if I did something I expected to succeed, it would seem to stop. Any text above that command would appear. No error message, no de-bugging.
But I didn't think to look in our error log. I see things like:
Could not initialize class com.microsoft.schemas._2003._10.Serialization.Arrays.ArrayOfstring
or
org.apache.axis.description.TypeDesc.(Ljava/lang/Class;Z)V
At least it's not a mystery anymore. Thanks again for suggesting the error log.

Accessing java classes from javascript

Hi,
I have the following javascript function
function testjava {
    var myString = new java.lang.String("Hello world"); // line 1
    alert("len:"+myString.length()); // line 2
}It gives me a error at line 1 saying "'java' is undefined" in IE browser 5.5 sp2. But, both the lines execute correctly in netscape 6.
Can someone please help..
Thanks,

It seems that IE 5.5 doesn't support accessing java classes in JavaScript, so try to install IE 6 to see if it works or maybe, you doesn't have installed propertly support for JVM in IE.

Accessing utility classes from ebj

I have a session bean trying to access a utility class in the lib directory (same
directory as weblogic.jar). I have packaged it into a jar file and set the classpath
pointing to the file in the startWeblogic.cmd file. I compiled and depolyed the session
bean and it runs fine until it starts to access the class. I got NoClassFoundException.
I have tried to shut down and restart the server without any success. Anyone can

Either you have a typo and the class is not in the classpath. You can prove
this by running
javap on the class using the same classpath as your startWebLogic script.
Or, as I suggested in the last response, it's not really standalone. The
jar probably has a

Accessing IFS classes from Weblogic

Can I access the classes of IFS from within Weblogic by adding the IFS jars to the Classpath of Weblogic?
Also how does EJBs work with IFS?

I'm doing exactly the same thing that you are asking. first install ifs client on weblogic server, so that all ifs jar files are on weblogic. then do this in the weblogic class path file:
REM ------------------ IFS CLASSPATH ------------------------
SET IFS_CLASSPATH=d:\Oracle\Ora81\ifs1.1\lib\adk.jar;d:\Oracle\Ora81\ifs1.1\lib\clientlib.jar;d:\Oracle\Ora81\ifs1.1\lib\cmdlineutils.jar;d:\Oracle\Ora81\ifs1.1\lib\cup.jar;d:\Oracle\O ra81\ifs1.1\lib\http.jar;d:\Oracle\Ora81\ifs1.1\lib\oemadmin.jar;d:\Oracle\Ora81\ifs1.1\lib\release.jar;d:\Oracle\Ora81\ifs1.1\lib\repos.jar;d:\Oracle\Ora81\ifs1.1\lib\utils.jar;d: \Oracle\Ora81\ifs1.1\lib\webui.jar;d:\Oracle\Ora81\ifs1.1\settings
and include IFS_CLASSPATH in your weblogic path.
restart weblogic and u'll have all ifs classes for your use.

In onLoad JavaScript, I'm getting "Error: Permission denied to access property 'classes'" when I access Components.classes; how do I enable that permission?

I need to emulate several ActiveX functions in my client's web application. I have located several Mozilla web pages that describe how to do the things I need, and I have attempted to implement those instructions. However, I can't seem to get past the first line of code. In my web page, I am calling a JavaScript function using the onLoad attribute of the <body> tag. I am using the Navigator object to determine that the browser is Firefox. I then attempt to access the extension classes using the following code on lines 51 and 52 of the Download.js file:
var C = Components;
var CC = C.classes;
The Web Console gives me these two messages:
[13:51:55.621] The Components object is deprecated. It will soon be removed. @ http://distribution:781/NewDDI/DownLoad.js:51
[13:51:55.621] Error: Permission denied to access property 'classes' @ http://distribution:781/NewDDI/DownLoad.js:52
How do I enable adequate permission to be able to access the Components classes?

I think Components is available only in extensions (or otherwise privileged code) and not in ordinary web pages.
