HTMLB events in AbstractPortalComponent
Hello,
I have a portal component that inherits from AbstractPortalComponent. I'd like to use HTMLB and its controls (tableView for example) to display the data in the portal. But how do I have to do the event handling for the HTMLB controls? Usually one would say:
<hbj:tableView onNavigate="onNavigate" ... />
But how do I have to handle this event in my class that inherits from AbstractPortalComponent? Do I have to use the doRequestEvent() method? If so, what's the name of the event? Or do I have to implement a onNavigate() method - as if I would use a JSPDynPage?
Or is it not possible to use HTMLB controls and a AbstractPortalComponent together?
Kind regards, Lars
hi,
Try this.
IPageContext context = PageContextFactory.createPageContext(request, response);
// get the event
Event event = context.getCurrentEvent();
if (event.getAction().equalsIgnoreCase("onNavigate")) {
//write your event handling method
Regards,
Srinath

Handling HTMLB events in BSPs???
Hi all,

Events in AbstractPortalComponent
Hi,
My AbstractPortalComponent dynamically builds a Form component with a collection of InputFields, RadioButtons and a Button for submit.
I can handle the "submit" event just fine, but what I would like to do is retrieve an array of components (all input fields and radio buttons attached to the form). The reason is that my component ids are generated dynamically, but with a specific naming convention. I was trying to avoid having to persist the component id names.
I have tried using getComponents from IPageContext and Form.iterator, but my array is empty.
Does anyone know if this is possible or do I just need to accept having to persist the component ids?
Thanks in advance for any advice.
Regards,
AnnHi Umair,
I finally figured it out. I found a method that produced exactly what I needed.
Below is a snipet of code that will list ids of the components associated with a form. For my case, it listed my radio buttons, input fields and button. I did not "id" my text views, so I am not sure if it will list those.
Iterator nameList = context.getOldForm().getRegisteredElementNames();
if (nameList == null)
response.write("Name List is null<br>");
else
while (nameList.hasNext())
String name = nameList.next().toString();
response.write("<br>Element Name:" + name);
Thanks for your reply though!

EP 6.0 SP2: Update a HTMLB TableView after onClick Event
Hello,
i generate a TableView from a JDBC database selection.
Outside this TableView there are 3 Buttons.
Now the problem:
If one of the buttons will click, the TableView has to be updated with a new database result. Have somebody an idea, how to update the TableView?
StephanCould you be more precise?
Default behaviour/coding is that an onClick event effects a request to the server - as your component/dynpage handles this request, you should be able to present anything that you like on this occasion. Maybe you code does not react to the HTMLB event properly?

Proplem: Access HTMLB controls from java code
Hi,
I am new to iView development for EP6. So my problem should be easy to solve (for you ).
I created in the NW Dev Studio a JSP DynPage.
The following files were created or edited:
1. JSP file (created)
2. java file (created)
3. portalapp.xml (edited)
In order to make the page running (proccessing) I changed the following things:
1. JSP file Add taglib reference to HTMLB-class
2. portalapp.xml Remove the native property so the JSP file will not be accessed directly.
Now I want to do the following:
On the JSP page I placed severeal HTMLB controls (textViews).
From the java code I try to access these controls in the doProcessBeforeOutput method and change/set values.
But I get all the time a null-Exception.
Code (JSP)
<%-- mcmsprovider.jsp --%>
<%@ taglib uri= "tagLib" prefix="hbj" %>
<hbj:content id="cntMcmsProvider" >
<hbj:page title="MCMS Provider Dynpage">
<hbj:form id="frmMcmsProvider" >
<hbj:textView id="tvwScript" encode="false"></hbj:textView>
<hbj:textView id="tvwStyle" encode="false"></hbj:textView>
</hbj:form>
</hbj:page>
</hbj:content>
Code (JAVA):
public void doProcessBeforeOutput() throws PageException {
this.setJspName("mcmsprovider.jsp");
TextView tvw = (TextView) this.getComponentByName("tvwStyle");
tvw.setText("Here the dynamic text");
I also tried to add raw text to the form but also null excpetion:
public void doProcessBeforeOutput() throws PageException {
this.setJspName("mcmsprovider.jsp");
Form frmCurrent = (Form) this.getForm();
frmCurrent.addRawText("<h3>This comes from here</h3>");
My goal is to dynamically add controls to the form, but until now I think it will be a dream:
public void doProcessBeforeOutput() throws PageException {
this.setJspName("mcmsprovider.jsp");
Form form = (Form)this.getForm();
TextView tvw = new TextView("tvwDynamic");
tvw.setText("Here the dynamic control");
form.addComponent(tvw);
The normal page processing runs:
public void doProcessBeforeOutput() throws PageException {
this.setJspName("mcmsprovider.jsp");
Any help is greatly appreciated.Eike

Also, I am getting an error on the following Import statement:

Any Idea why this would be happening?

Handling events in BSP application using WML tag Extensions
Hello Everyone ,
We are developing a BSP applications for Mobile handheld using WML tag library. I am looking for some code samples to know how we can handle evevents inside the BSP using the WML tag library.
Can any one of you plesae help us by placing a code snippet for handling onInputprocessing() methods (BSP Using WML Tag extensions).
I mean to ask how we can handle events inside the BSP applications that uses the WML tag library.
I know about how to handle BSP events using HTMLB and XHTMLB tags frameworks.
Thanks for your help in advance.
Thanks,
GreetsonIs this WML tag library something that is supplied by SAP u2013 as a BSP Extension Element? Or are you just using WML tags directly in your layout? I can tell you in general that if you want to generate HTMLB events from regular HTML code you can generate the JavaScript calls using the htmlbEvent tag of the BSP extension library. However your tags have to be running within an HTMLB Content tag for this to work.
If you want to work totally without HTMLB then you need to use the simple HTTP Post but format the input name as OnInputProcessing(<function code>) like this:
<input type="submit" name="OnInputProcessing(ok)" value="OK">
This will cause the OnInputProcessing event handler to trigger without needing any HTMLB tags (this is how it was done in WebAS 6.10 before we BSP Extensions). -
I cant import com.sapportals.htmlb.*
Hi!
I just installed netweaver and started out by making a new portal application project. After that I made a new portal application object but when I compile my java-file I get errors regarding the following imports.
import com.sapportals.htmlb.*;
import com.sapportals.htmlb.enum.*;
import com.sapportals.htmlb.event.*;
import com.sapportals.htmlb.page.*;
import com.sapportals.portal.htmlb.page.*;
import com.sapportals.portal.prt.component.*;
Error: The import com.sapportals.htmlb cannot be resolved.
I know that the error might be about me missing af reference to some jar-file which contains the packages. Am I wrong?
Regards AndersHi Anders,
Have you downloaded the PDK plugin for EP6? If so, assign yourself the Java Developer role, and download the required jar files. Login to the portal Java Development>Development>Downloads. Download and unpack the Portal Archive Wizards into your eclipse\plugins directory. Then create classpath references to the required jar files in your par file .classpath file. For example, htmlb.jar
<classpathentry kind="lib" path="C:/portal/eclipse/plugins/com.sap.developmentTools.libs_1.2.0/htmlb.jar"/>
Hope this helps,
Marty
PS.
If you dont have the pdk plugin, here is a workaround (assuming you have a portal installed). You can copy the jar files to your local directory in order to successfully compile a par project. For example the following three jar files to your eclipse\plugins directory on your local machine. Then in your classpath, create entries for the ones you require (in your case, htmlb.jar). So something like:
<classpathentry kind="lib" path="C:/portal/eclipse/plugins/com.sap.developmentTools.libs_1.2.0/htmlb.jar"/>
Under your portal, C:\usr\sap\<instance>\j2ee\j2ee_00\cluster\server\services\servlet_jsp\work\jspTemp\irj\root\WEB-INF\portal\portalapps\com.sap.portal.htmlb\lib contains an htmlb.jar and an htmlbbridge.jar
C:\usr\sap\<instance>\j2ee\j2ee_00\cluster\server\services\servlet_jsp\work\jspTemp\irj\root\WEB-INF\portal\system\lib contains a prtcore.jar file -
Hi,
I have developed a BSP and implemented the way Brian described in the Apprach 3 of the weblog mentioned below. In the method of new class that handles the server event(method name is same as server event), How do I access the model instance that I used in my BSP?
BSP Programming: Handling HTMLB Events
/people/brian.mckellar/blog/2004/07/28/bsp-programming-handling-htmlb-events
Thanks,
SureshBrian it's Good Idea to create in Controller Class or creating event handling methods within the model class. But I would like to create s separate class just for Even handling alone, so that I can use wherever I want(in different BSP Applications).
1.I have created ZCL_EVENT_HANDLER_FORME.
2.Created Method HANDLE_MYBUTTONCLICK and passed
event_object as a parameter.
3. I have ZCL_MY_CONTROLLER and ZCL_MODEL for BSP.
4. Created instance of ZCL_MODEL and assigned it to the Controller Attribute.
5. Successfully dispatced the event from DO_HANDLE_EVENT to HANDLE_MYBUTTONCLICK method of CL_EVENT_HANDLER_FORME.
6. I don't know how to get the reference to the model in
HANDLE_MYBUTTONCLICK method of CL_EVENT_HANDLER_FORME.
Am I missing some thing....
