Please be more specific.

Is there an error occurs? If yes, please post.

Does your change_karo() method ever get called when the onclick event happens on your button?

Let's target one problem at a time.

rajesh.ghosh

Yeah Vadim,

Sorry to mess it Up...........

My issue is actually chnage_karo() method is not getting called, I want to call it through JSP

What I wanted to DO is to display  results of select object_name,r_object_id "+   " from dm_document where "+   "owner_name = "+"'"+getDocbaseSession().getLoginUserName()in DATA GRID and once displayed There is Button is JSP called GADDI onlCLick of this Button I want to navigate to Server Side JAVA class and from there a Clinet side even I want To call Which is  a simple Alert, But I am Not able to Do that :::::::::

Firstly, use DQL query tool in WebTop and DA as a reference example for datagrids. It dynamic but it is still very simple. See wdk.war for the source

Once you have that figured out then start playing with more advanced grids, which give fancy full row selects, and column resizing

Actually my final Work  is, watever is Displayed in DATAGRID I want to EDIt it in CLinet Side JSP, and then Update the Records fetched using THe JAVA CLass......

Not possible!!! with out of the box WDK data grids.

Time to start investigate an AJAX framework (dojo, scriptalicous, Ext-JS ...)

 YES I have DONE THAT , I am Able to See the Clent side EVENt where the JSP is getting Populated with this QUERY, buit LAter Part of my JOB is To EDIT those attribute Value,,,,,,  and Then UPDATE The same in REPOSITORY,......... Please suggest the Best way To Do it.......


 In that CONTEXT the LINK That you sent Will that be helpful?

VadimYakovlev

Let's try

JSP:


<dmf:button runatclient="false" onclick="customMethod"

Component class

 public void customMethod(Button button, ArgumentList argumentList) {....

rajesh.ghosh

Yes Now what I need is To Process the Info That I changed in The First JSP and Populate it back to Content Serevr And Assure the CLinet That it has been Chnaged (May be with Alert)

VadimYakovlev

Were you able to get the chnage_karo() method called?

rajesh.ghosh wrote: Assure the CLinet That it has been Chnaged (May be with Alert)

Please re-state your question in the less confusing way. What exactly seems to be the problem?

Thank you

rajesh.ghosh

Yes that Method is being Called .... But Now the requirement is I want to get the Attribute Value(Existing Value from The JSP) into the JAVA Class and Update the Value into Docbase, then I want to confirm The user that Update has been Done inside Docbase... with an Alert on Client side....Hope I made myself Clear .this time.

VadimYakovlev

Yes, rajesh, now I understand the requirement.

But where exactly do you need help?

-Getting the value from the JSP?

-Updating value in the docbase?

-Notifying/Confirming the user?

With respect to the notifying/Confirming the user, the more "common/traditional" way would probably be to use the WDK Message Service. It will display the message in the standard message bar.

That is unless you absolutely have to use alert();

Example

MessageService.addMessage(this, "NLS_ID_OF_YOUR_CUSTOM_MESSAGE");

Where "this" is the reference to the Component Class

NLS_ID_OF_YOUR_CUSTOM_MESSAGE - is the nls bundle property name defined in one of the .properties file in your customization

What WDK client is it btw? Taskspace? Webtop?
