Question on HTMLB

Hi,
I have a list of data in a Iterator.
I want to iterate through it and sisplay the values in grid layout cells within the grid layout.
For this I need grid layout cells to be created dynamically. So can the rowIndex property be set to say "<% =counter %>" where counter is an incrementing variable during the iteration.
When I did this I get this error:
An exception occurred while processing a request for :
iView : DynOne.DynOne
Component Name : DynOne.DynOne
For input string: "".
Exception id: 03:13_18/09/06_0177_17835450
See the details for the exception ID in the log file

Hi,
Yes the row index can definetely be set to the jsp expression as you said like <%=counter %>.
I think the counter variable you used is of integer type,try converting it to string and use the string variable bcoz rowIndex property shud be set to string only.
Hope it works..
Also Can you post the detailed error?
Cheers,
Santhosh

Question about HTMLB:tableView with nested tag

Dear experts.
1. I have one question that can I code like below.
2. And what is the mean of "$something$". when I run the page I met the error $TVCID$ is no more supported from design2003.
<htmlb:tableViewColumn columnName = "myicon"
 type = "user"
 title = "Image"
 horizontalAlignment="center" >
 <htmlb:link id = "$TVCID$"
 onClick = "$CARRNAME$"
 tooltip = "$CARRNAME$">
 <htmlb:image src = "$TVCVALUE$"
 alt = "$TVCVALUE$"
 tooltip = "$CARRNAME$" />
 </htmlb:link>
</htmlb:tableViewColumn>

Hi.
You have more options to solve the problem.
First you can set your design to 2002.
<htmlb:content design = "DESIGN2002" >
or
you can use an iterator
or
you can use the following code
<htmlb:tableViewColumn columnName = "TVCVALUE"
 type = "LINK"
 linkClickTarget = "ONCLICK" (<- InputProcessing)
 title = "Image"
 horizontalAlignment = "center"
 tooltip = "CARRNAME" >
</htmlb:tableViewColumn>
Hope this helps

Question on HTMLB page form Validation

Hi Group,
How to validate a HTMLB page?
Like suppose, I have a few input fields and I hope we can go with using a Java Script in it to validate the form. But, how to do validate?
Please let me know how to valid some input fields in HTMLB page?
Thanks in advance.
Regards,
Vishnu.

ok what you are asking is,
if the check is successfull the form should get submitted and else it should not get submitted and stay on the same page.
define the htmlb:button with both onclientclick and onclick.
in on clientclick add your js.
in that js, if the check fails add the following line
htmlbevent.cancelSubmit = true;
sample code.
onClientClick = "var Check = false; Check = confirm('k2?');if(Check == false){ htmlbevent.cancelSubmit = true; }"

Webdynpro interview questions and answers

hi friends
i need webdynpro interview questions and answers
urgently
thanks

Hi Ramachandran,
There is a seperate book in sap Press for interview question but will cost a lot and i dont think it is easily available in India.
But then, if you are aware of Webdynpro for Java, you dont have to worry a lot. Since Webdynpro is a new technology, People who really want to recruit people will stick to basic questions.
I can give some examples below
1. What is adaptive RFC and How to Use it
2. What are the table variants and how to use each of them
3. Can ask about tree and trees in table.
4. What is singleton and supply function
5. Some basic Portal Admin Question.
6. basic customization question using HTMLB
7. What is the diff between Adaptive rfc and adaptive web servie and who to use both.
8. Diff between drop down by key and drop down by index.
9. diff between Link by action and link by url and other Basic UI questions.
10. Might ask about merge functionality of NWDI if used.
11. Might ask about dynamic Ui and Context Generation
12. and So on.
I have attended Few interviews and know many of those questions. I cannot put every thing here.
But Dont worry. If the interview is for Selecing people and not to show ego of how good the person who is interviewing is , will ask basic to understnd how good the candidate is in understanding basics as rest all have the document in SDN.
Hope it helps.

Hbj:button properties

Hi,
I have a quick question about htmlb buttons in JSPs. I just have a test JSP like so:
<hbj:content id="myContext" >
<hbj:page title="PageTitle">
 <hbj:form id="myFormId" >
 <%-- used in the JSP DynPage to access the input field and retrieve the input of the user --%>
 <hbj:inputField
 id="user_name_input"
 type="STRING"
 design="STANDARD"
 width="250"
 maxlength="30"
 />
 <hbj:button id="change_pass_button"
 text"Change Password"
 tooltip="Change Me"
 width="100"
 design="EMPHASIZED">
 </hbj:button>
 </hbj:form>
</hbj:page>
</hbj:content>
And I am unable to see the button. Does there need to be an onclick method associated with this button to see the actual button? Do I need to set myFormId.defaultButton(...) to the change_pass_button. When I did that, the PRT generated an error saying that change_pass_button was an unresolvable symbol. I just want to see what HTMLB buttons look like. Thanks!

Hello,
You get very good help in Java Development ---> examples section. Here is the example
<hbj:button
id="Send_Button"
text="Save"
onClick="onSendButtonClicked"
width="70"
design="EMPHASIZED" >
</hbj:button>
Thanks,
Praveen
if you want to validate with javascript u need to use onClientClick event.
<hbj:button
id="Send_Button"
text="Save"
onClick="onSendButtonClicked"
onClientClick="confirm_save()"
width="70"
design="EMPHASIZED" >
</hbj:button>

HTMLB classlib question...

Hi, I have a question relating to the HTMLB library,
Currently my iView JSP has:
<hbj:link
 id="link1"
 text="Link to google"
 reference="http://www.google.com"
 target="_TOP"
 tooltip="this takes you to: http://www.google.com"
 onClick="LinkClick"
 />
If I wanted to add the fontSize attribute, how can I do this? I know I have to use the java command "setFontSize (LinkFontSize.fontsize)", but where would I do this? I currently have a JSPDynPage.java that does calls my jsp's is this where I am suppose to put code?
Or do I have to create entire page in Java code(servlet?) or I can create the JSP page, and then in Java use the attribute-changing methods like above?
I am a beginner in all of this and would greatly appreciate any code examples or suggestions you may have. Thank you for your help and patience.
Thank you very much,
Baggett.

Hi Prakash, I'm trying to make the font size 16px, how can I do this? I am trying:
<% LinkFontSize size = new LinkFontSize("16");
link1.setFontSize(size);%>
I see that there is a constructor available but it is protected, how would I be able to use it?
Thanks so much!
Baggett.

HTMLB Link usage, question

I am new to HTMLB, question
   Button myButton = new Button("submitButton");
   myButton.setOnClick("sendName");
   myButton.setText("Go to Yahoo");
   myButton.setTooltip("Click here to go to Yahoo.");
the implementation of onSendName
public void onSendName(Event myName) throws PageException {
           String url = "http://www.yahoo.com";
           Link lk = new Link("mylink", "yahoo");
           lk.setReference("http://www.yahoo.com");
           lk.setTarget("_blank");
                  ??????? now what???
                 //How do I get to the link?
                 Please help fill in, appreciate:
   If this is the not the right way, any other way to achieve this?
thanks much.
Dave Wang

Yes, Eric, thanks for the answer. in this case. I can substitute the button with a link. But
In another scenario, I have a tableview, then every cell clicked will lead to a url generated based on the content of the table cell,
for example, cell(1,2)="userABC", onCellClick() funciton will generate a Link to: "http://xxx?userid=userABC". When user clicks cell(1,2), it should go to the generated URL.
It would be great if I can generate the link then direct the browser to the URL at onCellClick().
How do I handle this case?
thanks for any suggestions.

Java iview htmlb & jco question

hello all,
I am writing an Java iView to pull some data from an
R/3 table & displaying that as a LINE chart.
I've already got the portion of getting data from R/3
by creating a shim function that returns the table.
Now i want to display that using htmlb.Chart
I can seet the JCO.Table as my JCOChartModel easily enough
however the Table returns to me multiple rows
(data that will be used elsewhere) but there are only
two rows i want to use as the source for the Chart.
Is there any way to limit the Chart to those two rows
or do i need to (in my opinion wastefully) create
a Vector and duplicate the data from those two
rows to use for Chart?

Hi Srivatsan,
I need to write a java iview to pull some data from an R3 table. But I dont know how :S
I did something with jco in EP 5, but now with EP 6 I'm confused with the term JCA.
What do you do to connect to R3 ? Could you share your code ?
Thanks and regards from Mexico !!!

HTMLB Tableview: questions..;

Hello,
Simply I output my table as follows :
<htmlb:form>
<htmlb:tableView id = "tv1"
 visibleRowCount = "10"
 selectionMode = "lineEdit"
 table = "<%=mytable%>"
 iterator = "<%=iterator%>" />
</htmlb:form>
(NOTE: where iterator is type IF_HTMLB_TABLEVIEW_ITERATOR)
Ok, its nice, but I need to customize things a bit. I have 5 fields... and I want 4 uneditable, and the 5th able to be updated and modified back into the SAP table.
How can I do this?
Thanks,
Timothy

Hello,
I have read many times the iterator weblogs, especially 830. I understand most but still have trouble. Allow me to show you what I have, and please tell me what is wrong.
My BSP, index.htm:
<%@page language="abap" %>
<%@extension name="htmlb" prefix="htmlb" %>
<htmlb:content design="design2003" >
<htmlb:page title="EPCOT" >
 <%
SELECT * FROM ZEPCT002 INTO TABLE epcots
 WHERE ZANNE = anne
 AND ZPAYS = pays.
 %>
 <htmlb:form>
 <htmlb:tableView id = "tv1"
 visibleRowCount = "12"
 selectionMode = "lineEdit"
 table = "<%= epcots %>"
 iterator = "<%= iterator %>" />
 </htmlb:form>
</htmlb:page>
</htmlb:content>
For my iterator, I have made the 5th field an input field (CL_HTMLB_INPUTFIELD). And the 6th field an ICON:
image2->onclick = 'OnSaveClick'.
 image2->src = cl_bsp_mimes=>sap_icon( `ICON_SYSTEM_SAVE` ).
I want, when user selects a line, enters text in this 5th field, and then clicks the icon... an event to write/modify directly this change into my table (SAP table I created). So, for index.htm, in OnInputProcessing, I have:
DATA: event TYPE REF TO CL_HTMLB_EVENT,
 id type string,
 row type string,
 col type string,
 other type string.
CLASS cl_htmlb_manager DEFINITION LOAD.
clear: event, id, row, col, other.
event = CL_HTMLB_MANAGER=>get_event( runtime->server->request ).
id = event->id.
split id at '_' into other row col.
case col.
WHEN '6'.
?????
endcase.
My ????? is where I have tried many things and just dont get it. In weblog 830, I see what he is doing, but some things he does don't work for me, like:
id = htmlb_event->id.
 case htmlb_event->server_event.
 when 'OnUpdateUserClick'.
 data: event1 type ref to cl_htmlb_event_selection.
 event1 ?= htmlb_event.
 read table model->ug_users index i_row assigning <irow>.
this htmlb_event->id, htmlb_event, and model->ug_users... for these I get syntax errors.
So, could you tell me what I need to do here?
Any guidance would be greatly appreciated,
Thanks,
Tim

this error is not coming only with one control, any code we written after the last control that is checkbox group.
i don't think it is a controls error or any syntax error.
is there any code length limit in the jsp pages? if not what might be the problem?
kindly consider the error.

HTML Tags in HTMLB or How to shrink HTMLB ?

Hi,
I have a JSP page using HTMLB tags, which works fine in EP5. I am migrated this JSP in EP6 SP6 and now it gives me the following message:
Error in executing a process for compilation, C:/usr/sap/EP6/JC00/j2ee/cluster/server0/apps/sap.com/irj/servlet_jsp/irj/root/web-inf/portal/portalapps/com.suncor.ci.continuousimprovement/work/pagelet/_sapportalsjsp_recordinputform.java:5262: code too large for try statement } catch(IOException jspioex) {} ^ C:/usr/sap/EP6/JC00/j2ee/cluster/server0/apps/sap.com/irj/servletjsp/irj/root/WEB-INF/portal/portalapps/com.suncor.ci.continuousimprovement/work/pagelet/_sapportalsjsp_recordInputForm.java:4303: code too large for try statement try { ^ ...

The error is because of intense use of HTMLB.
The whole JSP page is one form.
I did some research and found out that the Servletsize is limited to 65k Byte.
Indeed, when i removed some HTMLB tags, it was working fine....
The suggestions was to use the Include Directive
<@ include page="other.jsp" > This will load the other jsp at Runtime.
When i did this, the content of the HTMB was not converted to HTML, but it only copied the HTMLB tags directly after the <body>. (I included the <%@ taglib uri="tagLib" prefix="hbj" %>)
When writing <tr> or <td> directly (to compress the HTML lines) using the JSPWriter (out) instead of the HTMLB tags, my HTML was ignored and did not appear in the HTML output.
My question is: How can I add HTML in HTML or how can I shrink a huge HTMLB form ?
Any ideas are welcome...
Kai

Hallo Kai,
Asking about JSP in the BSP forum is about 66% correct. Both have SP in the name. Unfortunately the B is very important for us, and we are shy when it gets to gets about J. BSP is an environment similar to JSP, but based on ABAP. We also have a rendering library called HTMLB. But after that, the similarities stop.
Unfortunately, we can not help you more, and would recommend any of the Java programming forums.

Can I launch a new JSP on a popup window, when cliking a HTMLB button ?

Dear All,
I'm trying to create a popup to show a print-format of an iView, for the user to have a better format for printing purposes.
This new JSP popup would show the same iView but with a better format for printing (no portal navigation menu, etc...)
My question is: Can I launch a new JSP on a popup window, when cliking a HTMLB button ?
Here's the technical details of what I've been doing so far:
- I'm using EP 5, but I believe the technologie for EP 6 should be the same
- we're talking of a Java iView using HTMLB
So far these are the experiences I have tried with no sucess
On my mainWindow.jsp I have this piece of code, but it doesn't work:
(etc...)
<%
ResourceBundle res = componentRequest.getResourceBundle();
IResource rs = componentRequest.getResource(IResource.JSP, "printFormat.jsp");
String JSP_URL = rs.getResourceInformation().getURL(componentRequest);
%>
(etc...)
<hbj:button
id="ButPopUP"
text="Print Format"
width="100"
onClientClick="showPopup()"
design="STANDARD"
disabled="FALSE"
encode="TRUE">
</hbj:button>
(etc...)
<script language="Javascript">
function showPopup(){
mywindow = window.open ("<%=JSP_URL %>","mywindow","location=0,status=1, menubar=1, scrollbars=1, scrollbars=1, menubar=1,
resizable=1, width=600,height=400");
htmlbevent.cancelSubmit=true;
</script>
(etc...)
Thank you very kindly for your help.

Hi Kiran,
sorry for the late reply.
Thank you so much for your JAR file.
Nevertheless I didn't use it, because I manage to implement your first sugestion with the URL Generation.
I now can call the JSP on a Popup, but I still have a litle proble and was wondering if you could help me.
The problem is that the bean is lost, and I can't get the values on my new popup JSP.
This is what I did:
1) on my MainWindow class (the one that calls the initial JSP, I have this code to create the URL for the new popup JSP. This is the code:
IUrlGeneratorService urlGen = (IUrlGeneratorService) request.getService(IUrlGeneratorService.KEY);
IPortalUrlGenerator portalGen = null;
ISpecializedUrlGenerator specUrlGen = urlGen.getSpecializedUrlGenerator(IPortalUrlGenerator.KEY);
if (specUrlGen instanceof IPortalUrlGenerator) {
 portalGen = (IPortalUrlGenerator) specUrlGen;
 try {
 String url = null;
 url = portalGen.generatePortalComponentUrl(request, "Forum_IS.popvalues");
 myBeanDados.setPopupURL(url);
 } catch (NullPointerException e) {
 log.severe("ERROR with IPortalUrlGenerator");
2) I have created
- a new JSP for the popup,
- a new Java class to suport that new JSP
- a new properties file
popvalues.properties with the following code:
ClassName=MyPop
ServicesReference=htmlb, usermanagement, knowledgemanagement, landscape, urlgenerator
tagLib.value=/SERVICE/htmlb/taglib/htmlb.tld
MyPop is the new class that is associated with the new JSP popup.
The problem now is that the bean was lost.
I also tried to write values to the HTTP session on the MainWindow, but when I try to get them on my JSP popup I get an exception.
How can I pass the values (or beans) to my new popup JSP ?
Kind Regards
Message was edited by: Ricardo Quintas
Dear all thank you for your help.
I have managed to solve the problem I had.
Here's the problem + solution sumary.
I have to remind you that we are talking of EP 5, PDK 5 (Eclipse version 2.1.0), with JAVA JDK 1.3.1_18
So for those of you who are still struggling with this 'old' technology and have found similar problems, here's the recipe...
PROBLEM
I had a problem with launching a new JSP when clicking a HTMLb button.
I wanted to create a JSP to present a 'print-format' of an iView.
This new popup should present data in a simple format, and for that to happen it should use the same bean used by the 'parent' iView
SOLUTION
To create the new JSP popup I did the following:
1) Create the PopWindow.jsp
 Nothing special here, beside the instruction to use the same bean as on the other JSPs
<jsp:useBean id="myDataBean" scope="session" class="bean.DataBean" />
 2) Create the associated JAVA class
MyPop.java. This class will be used to call the PopWindow.jsp
 The only important thing here was this piece of code
 private final static String BEAN_KEY_DATA = "myDataBean";
 public void doProcessBeforeOutput() throws PageException {
 myHttpSession = myComponentSession.getHttpSession();
 myDataBean = (DataBean) myHttpSession.getAttribute(BEAN_KEY_DATA);
 myComponentSession.putValue(BEAN_KEY_DATA, myDataBean);
 this.setJspName("PopWindow.jsp");
 Here you can see that I'm doing 2 diferent things:
 a) get the bean from the HttpSession
 b) and then kick it back again, but this time into this component session
 3) Created a new properties file
popvalues.properties. This file contains the follwing code:
 ClassName=MyPop
 tagLib.value=/SERVICE/htmlb/taglib/htmlb.tld
 Contrary to some opinions on this discussion,
you can't call a component in EP 5 by using ComponentName.JSPname.
Or at least that didn't work for me.
You nee to use an aproach like this one ComponentName.NewProperiesFileName
4) On my main class MainClass.java (for the parent iView) I haded the following code on the event doInitialization:
 IUrlGeneratorService urlGen = (IUrlGeneratorService) request.getService(IUrlGeneratorService.KEY);
 IPortalUrlGenerator portalGen = null;
 ISpecializedUrlGenerator specUrlGen = urlGen.getSpecializedUrlGenerator(IPortalUrlGenerator.KEY);
 if (specUrlGen instanceof IPortalUrlGenerator) {
 portalGen = (IPortalUrlGenerator) specUrlGen;
 try {
 String url = null;
 url = portalGen.generatePortalComponentUrl(request, "MyMainApplication.popvalues");
 myDataBean.setPopupURL(url);
 } catch (NullPointerException e) {
 etc...
 The idea here was to build dinamicaly a URL to call the popup.
 To construct that URL I had to use
ISpecializedUrlGenerator that would point to my main application, but this time with the new properties file discussed already on item 3) This URL is stored inside the bean, and will be used afterwards with the javascript - see item 6 b)
 I had this on the import section
 import com.sapportals.portal.prt.service.urlgenerator.IUrlGeneratorService;
 import com.sapportals.portal.prt.service.urlgenerator.specialized.IPortalUrlGenerator;
 import com.sapportals.portal.prt.service.urlgenerator.specialized.ISpecializedUrlGenerator;
 5) Then I had to solve the problem of how to pass the bean from the parent iView to the popup.
 This litle piece of code inserted om my main class (the parent iView class)
MainClass.java solved the problem:
 import javax.servlet.http.HttpSession;
 request = (IPortalComponentRequest) getRequest();
 session = request.getComponentSession();
 session.putValue(BEAN_KEY_DATA, myDataBean);
 myHttpSession = session.getHttpSession();
 myHttpSession.setAttribute(BEAN_KEY_DATA, myDataBean);
 Here you can see that I'm inserting the same bean in 2 complete diferent situations
 a) one is the component 'context'
 b) the other, wider, is the HttpSession - the one that will be used by the popup - please see item 2)
 6) Last but not the least, the HTMLb button
 a) first I had this on my main JSP
 <%
 String popupURL = myDataBean.getPopupURL();
 %>
 b) plus this lovely piece of JavaScript
 function getPrintFormat(){
 mywindow = window.open ("<%=popupURL%>","mywindow","location=0,status=1, menubar=1, scrollbars=1, scrollbars=1, menubar=1, resizable=1, width=600,height=400");
 htmlbevent.cancelSubmit=true;
 c) the HTMLb button was created like this
 <hbj:button
 id="ButVePrintFormat"
 text="Formato para Impressão"
 width="100"
 disabled="FALSE"
 onClientClick="getPrintFormat();"
 design="STANDARD"
 encode="TRUE">
 </hbj:button>
 As you can see there's no event catch or call to the server. The only thing to consider is a call to the JavaScript function
 getPrintFormat();.
 Está todo lá dentro.
 That's all there is to it.

Using library com.sapportals.htmlb.*;

Hi,
i had created a portal aplication in the wizard. And i had joined this library (com.sapportals.htmlb.*;) to my program, meanwhile i had initialized my new form and other components of my form...such as textviews,labels, buttons and so on..
The question is, when i make the deploy in a file '.par' to the portal i can´t see the changes i had made in the components of my form...can anybody tel me why? can you give references to study implementations of this library?
Regards,
Hugo

Hi Hugo,
Assuming that you have installed the PDK for Java,
have you tried cleaning the par file and re-deploying?
This is done via: Java Development>Development>Component Manager>Archive Remover> From here select your particular project and hit clean. This removes the old code entirely from the system and you can redeploy with satisfaction that the old code will not be referenced.
