Can we override the jspService method?

Can we override the jspService method in jsp file?

You can. But the use depends on the webcontainer used. For every kind of webcontainer you likely have to rewrite the stuff.
In case of Tomcat, you simply have to extend the HttpJspBase and implement accordingly.

How to override the create method invoked by a create form?

Hello everyone, I'm using ADF Faces and have the next question:
How can I override the create method which is invoked by a create form to preset an attribute in the new row (the preset value is not fixed, I have to send it to the method as a parameter as it is obtained using an EL expression)?
In the ADF guide I read how to override a declarative method (Section 17.5.1 How to override a declarative method), but this explains how to do it with a method that is called by a button. I don't know how to do the same with a method which is called automatically when the page is loaded.
I also tried overriding the view object's createRow() method to receive a parameter with the preset values but it didn't work, I believe that was because the declarative create method is not the same as the view object's createRow. This caused the form to display another row from the viewobject and not the newly created one (I also set the new row into STATUS_INITIALIZED after setting the attribute).
Well, I hope my problem is clear enough for somebody to help me.
Thank you!

Hello,
I'm not sure you can do it with standard generated Create Form.
In your view object you'll need to create your own create method with parameters, publish it to client interface and invoke instead of standard generated create action in page definition.

Help needed in overriding the finalize() method!

Hi
I need some help in overwriting the finalize() method.
I have a program, but at certain points, i would like to "kill" a particular object.
I figured that the only way to do that is to make that object's class override the finalize method, and call it when i need to kill the object.
Once that is done, i would call the garbage collector gc() to hopefully dispose of it.
Please assist me?
Thanks
Regards

To, as you put it, kill an object, just null it. This
will be an indication for the garbage collector to
collect the object. In the finalizer, you marely null
all fields in the class. Like this:
public class DummyClass
String string = "This is a string";
Object object = new Boolean(true);
public void finalize() throws Throwable
super.finalize();
string = null;
object = null;
public static void main(String[] args)
//Create a new object, i.e allocate an
te an instance.
DummyClass cls = new DummyClass();
//Null the reference
cls = null;
This is a pointless exercise. If an object is being finalized, then all the references it contains are about to cease being relevant anyway, so there's no purpose to be served in setting them to null.
All that clearing a reference to an object does is to clear the reference. Whether the object is subsequently finalized depends on whether the object has become unreachable.
Directly calling finalize is permitted, but doesn't usually serve any purpose. In particular, it does not cause the object to be released. Further, calling the finalize method does not consitute finalization of the object. Finalization occurs when the method is called as a consequence of a garbage collector action.
If a variable contains a reference to an object (say a table), and you want a new table instead, then create a new table object, and assign its reference to the variable. Assuming that the variable was the only place that the old table's reference was stored, the old table will, sooner or later, get finalized and collected.

Can we override the Desktop LAF for Pages using backing Files ?

Hi
I have the following Look And Feel related requirement.
We have an global application level Skin which was applied at the desktop level using the .laf file.
But some of the pages require a totally different Look and Feel apart from the one defined at the desktop level.
To put the question in the other way,
Can we override the skin & skeleton defined at the Desktop level using the backing file (for page or portlet) ?
The following is the code snippet, which i used in the backing file to achive the above.
LookAndFeel lookAndFeel = LookAndFeel.getLookAndFeel(request);
lookAndFeel.setSkin(y_skin);
lookAndFeel.setSkeleton(y_skeleton);
lookAndFeel.reinit();
Here the y_skin & y_skeleton are the new set of skin & skeletion which i have created for the page.
when i ran the above snippet in the portal framework, i found the desktop level skin is getting applied
to the pages insted of the y_skin & y_skeleton.
Any help or directions .... for dynamically changing the skin & skeletion for pages will be appreciated.
Thanks & Regards
- Sachi

What you are doing looks valid.
this is the code that i have
public void init(HttpServletRequest request, HttpServletResponse response)
// Get the session from the request
HttpSession session = request.getSession();
// Get the LookAndFeel object from the PrimaryTheme in the request
LookAndFeel lookAndFeel = LookAndFeel.getLookAndFeel(request);
if (request.getParameter("defaultButton") != null)
//System.out.println("default skin selected");
session.setAttribute("skin", "default");
if (request.getParameter("textButton") != null)
//System.out.println("text skin selected");
session.setAttribute("skin", "text");
if (request.getParameter("classicButton") != null)
//System.out.println("classic skin selected");
session.setAttribute("skin", "classic");
String selectedSkin = (String) session.getAttribute("skin");
if (selectedSkin != null)
//System.out.println("setting skin and skeleton to: '" + selectedSkin + "'");
lookAndFeel.setSkin(selectedSkin);
lookAndFeel.setSkeleton(selectedSkin);
lookAndFeel.reinit();
}

How can I call the create method in BO from Application Service

Hello!
When I create a Business Object, CAF generates some methods automatically.
How can I call the create method in the BO from Application Service logic?
When i call the method then the entityManager and the sessionContext is NULL.
How can I initialize this?
Can anybody help me?
Thanks, Thomas

If you are using CE 7.11...
1) In the Application Services, add the BO as dependant object in dependencies tab.
2) In the implemention, add the following codes to call create method of the BO:
this.get<BO>.createMethod();

Can't override Button component methods

I've got a custom class that extends the Button UIComponent. I'm trying to override the drawEmphasized() function and a few public get/set functions. I get "1020: Method marked override must override another method." for each thing I try to override. The SWF that uses the custom button will compile and work, but I don't know if the failure is creating some of the strange behavior I see. The errors appear when I drag a component onstage, or save the FLA. This seems related: http://bugs.adobe.com/jira/browse/SDK-13877 but I don't know, I can't understand the fix. Any ideas? Thanks.

I found a workaround. Do not use the same class for Component Definition. Make a different class for use as a Component Definition. Make sure the same Inspectable tag and var declaration are in each class. So for the above extended button class, if you wanted to add a "myvar" inspectable variable, the code would be in another class as follows.
package
import fl.controls.Button;
public class testButtonDEF extends Button
[Inspectable(name="myvar", variable="myvar", type="String", defaultValue="")]
public var myvar:String = "";
Also see my related thread about Inspectable properties: http://forums.adobe.com/thread/453659

How can i invoke the set method before value change listener?

Hi,
My code is like this:
<af:selectManyCheckbox value="#{bean.statusList}"
                                 binding="#{bean.statusCheckBox}"
                                 label=" " autoSumit="true"
                                 valueChangeListener="#{bean.changeStatusList}"
                                 id="dc_smc1" layout="vertical"">
            <f:selectItems value="#{bean.statusBuckets}"
                           id="statusBuckets"/>
          </af:selectManyCheckbox>
public void changeStatusList(ValueChangeEvent valueChangeEvent)
//in this method, i want to set the statusList by myself, this is not the same with the ui.
public void setStatusList(List<String> statusList)
        this.statusList = statusList;
    public List<String> getStatusList()
        return statusList;
As i set the autoSumit="true", then no matter what i set the statusList in the method changeStatusList, it will be reset the value after invoke the method setStatusList, Therefore, it will always change the checkbox status through ui operation, i cannot change it through code.
Pl help me!
Thanks,
Emma

Emma, which jdev version do you use?
As you have set the value property to the list you try to change in the valueChangeListener method this is expected behavior. If the list is bound to the af:selectManyCheckbox values you can't change it with a set method.
It would help if you tell us what you are trying to do in a broader scope.

How can I override the startup window position?

Can I override a compiled labview 7 app with ini settings, command line options, via a registry edit, or other option?
Thanks,

Hello Mike
Besides saving the vi in a position, you also have a property node to determine window position at startup app.
Values can be fix, calculated from monitor specs, etc.
See attached doc.
Hope it helps

Can I override the default ReadObjectQuery for an entity and specify my own call

Hi,
I am trying to override the default ReadObjectQuery and the ReadAllQuery for an entity and supply my own call.The entities have to be read from the database using a StoredProcedure.I tried doing something like
Descriptor desc=evt.getSession().getDescriptor(Configuration.class);
desc.getQueryManager().setReadObjectQuery(new ReadObjectQuery());
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("CONFIGSVC");
call.addUnamedArgument("CATEGORY");
call.addUnamedArgument("CFGKEY");
call.addUnamedArgument("VALUE");
desc.getQueryManager().getReadObjectQuery().setCall(call1);
desc.getQueryManager().getReadObjectQuery().addArgument("CATEGORY");
desc.getQueryManager().getReadObjectQuery().addArgument("CFGKEY");
desc.getQueryManager().getReadObjectQuery().addArgument("VALUE");
When I try to execute the query
ExpressionBuilder builder = new ExpressionBuilder();
Expression expr = (builder.getField("category").equal("GOESVC.GETTDEV")).and(
new ExpressionBuilder().getField("configKey").equal("GOESVC.REQ")).and(
new ExpressionBuilder().getField("value").equal("$ENV.$ORIGIN.GOESVC.REQ"));
ReadObjectQuery query = new ReadObjectQuery(Configuration.class, expr);
session.executeQuery(query);
I can see in the log that it completely ignores the call I set and tries to execute using the default call and that too with incorrect mappings between the "entity" field names and the actual database field names.

Hi,
The "ReadObjectQuery" in a descriptor's query manager can only be used to change the primary key read query. It will be used only for a ReadObjectQuery that either has a selection key, selection object, or an expression that exactly matches the primary key.
If you have a non-primary key query that you want to use, you can add it as a named query to the descriptor's query manager.
I'm not sure of the primary key of your descriptor, assuming that it is a 3 part composite key, then your ReadObjectQuery procedure is defined correctly in the descriptor. However the ReadObjectQuery is incorrect, you must use "get" not "getField", also you must use a single expression builder.
i.e.
ExpressionBuilder builder = new ExpressionBuilder();
Expression expr = (builder.get("category").equal("GOESVC.GETTDEV")).and(
builder get("configKey").equal("GOESVC.REQ")).and(
builder.get("value").equal("$ENV.$ORIGIN.GOESVC.REQ"));
ReadObjectQuery query = new ReadObjectQuery(Configuration.class, expr);
session.executeQuery(query);
you could also do,
Vector key = new Vector(3);
key.add("GOESVC.GETTDEV");
key.add("GOESVC.REQ");
key.add("$ENV.$ORIGIN.GOESVC.REQ");
ReadObjectQuery query = new ReadObjectQuery(Configuration.class);
query.setSelectionKey(key);
session.executeQuery(query);
If the descriptor primary key is not 3 part, then add this query as a named query.
Descriptor desc=evt.getSession().getDescriptor(Configuration.class);
ReadObjectQuery query = new ReadObjectQuery();
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("CONFIGSVC");
call.addUnamedArgument("CATEGORY");
call.addUnamedArgument("CFGKEY");
call.addUnamedArgument("VALUE");
query.setCall(call);
query.addArgument("CATEGORY");
query.addArgument("CFGKEY");
query.addArgument("VALUE");
desc.getQueryManager().addQuery("findConfigSVC", query);
To execute the query,
Vector arguments = new Vector(3);
arguments.add("GOESVC.GETTDEV");
arguments.add("GOESVC.REQ");
arguments.add("$ENV.$ORIGIN.GOESVC.REQ");
session.executeQuery(Configuration.class, "findConfigSVC", arguments);

How can I override the DNS Servers and Domain Name used by my Airport Time Capsule?

The defaults picked up from my ISP's DHCP are to use the ISP's DNS servers and ISP's domain. I do not want this.
With my prior router I set the DNS servers to Google's Public DNS (8.8.8.8 and 8.8.4.4) and my domain to either "bannister.us" (which I own) or "bannister.home". I do not want simple names resolving to some ISP default. (Yes, I know exactly what this does.)
In the Apple AIrport Utility (version 6.3.2) the fields for DNS and Domain do not allow editing. (Why??)
Is there some way to override this?

Unfortunately not one that will work with the latest version TC.
The way around it is to use a different router.. It can be a very simple router.. I usually recommend units like the TP-Link WDR3600 as they take good third party firmware like gargoyle, openwrt, dd-wrt.. ie they have real controls and beyond that a proper Linux firmware with command line interface.
You can then change the TC over to static IP. It will not be the router.. but it will effectively become the local dhcp server.
I have adsl so I cannot reproduce your system.. I have a bridged modem.. a router.. AC66U.. and a TC.. but the TC is not in bridge.. it is in static IP mode.
Let me demonstrate.
By setting a range on the main router from 1-199 (leave a space.. ) so set the TC to 192.168.2.201 and then you can set DNS and domain as you like. Set the dhcp range (leave a space) you could use 203-253.. then I use the main router as 254.
It is brilliant.. all computers behind the TC receive the IP from the TC with whatever IP and dns (and domain although I haven't changed it).. Effectively the TC works as its own dhcp device.. but is merely a secondary dhcp server to the main unit.
(This gives me netflix which is why I do it.. from well outside the US).
It may be of use.
Why leave a space.. well it helps it to work.. I have not tested it but another person reported issues and found leaving a space .. ie last ip in the router.. 199, static ip 201.. first dhcp 203 (i used 205 to help me keep count!!). worked.. I have not tried to reproduce the problem.. so I reproduce the solution.. it might be like sheep jumping over the fence.. even if the fence was removed the sheep keep jumping over at the same place. Just say bahhh and do likewise.
