LinkToAction how to use it with parameter?

Hello,
searching for tutorials about the use of the LinkToAction I have seen that here is a possiblity in WD4J to use a context-node.
How can you pass a parameter in WD4A? (I am using a rowrepeater for a list of books and would like to pass the bookID to the event)
How can I do this?
Thanks a lot,
Vanessa

Thanks for your answer Lekha,
unfortunaltely I don't get the point.

Somehow I don't get the point. How can I pass the bookid to the method?
I have a rowrepeater. One of the elements is the link to the action. I will add the bookid as parameter. That is clear.
My problem is how to connect the bookid of the row that is displayed to the method? Is it just because of the name? I don't see any context I can associate?
Could you please go a little bit more in detail,
Vanessa

How to use the out parameter in client?

Does this error only occurs if you pass "lxh" or always?
Did you try passing a StringHolder Object rather than a NULL Object?
Perhaps you can post the error message!?

How to use ET_ATTACH importing parameter Function module BBP_PD_SC_CREATE

hi,
how to use ET_ATTACH importing parameter of Function module BBP_PD_SC_CREATE, my requirement is to create SC with attachment.
an example would really help.
Kind Regards,
Kailash.

Hi,
Generally we create the SC from ITS or Portal, and there in the Create SC screen , once you add the item into the shopping cart , in the Item details, there is the section called , Documents and Attachements, where in you can upload the attachments which ever you want. Sometimes the extn .DOC, .pdf and .xls are allowed. but that also you can check which are the Authorized files extns avaialbe in Backend R/3.
Using the FM RFC_READ_TABLE, in table pass TDWP and in the i_field pass 'APPSFX' and then you can get the authorized file formats. in Backend Transaction DC30 you can verify which are the allowed file formats.
Moreover for restricting the User from uploading the attachment BADI BBP_ITEM_CHECK_BADI can be implemented for raising the error message if required.
Regarding the ET_ATTACH, it is the structure of type BBPT_PDS_ATT_T, so you have to provide the complete details for this structure. Like : GUID, P_GUID ,LOGICAL_SYSTEM, DESCRIPTION, URL, TYPE,DISP_URL, PHIO_EXT ,etc.
Once all the entries are fine.
You can create the SC, but the recommeded way for creating the SC is thru ITS or Portal.
I hope this will help. Feel Free while asking questions.
Thanks and Regards,
Ankur Goyal

How to use Terminal with KeySpan USB serial adaptor cable?

I own a KeySpan model USA-19HS to use with our MacBookPro when working on clients networking equipment that require serial communication. I have used ZTerm with excellent luck, but it costs, and is yet another application that I dont really want. I would like to know if any one out there has exacing instructions on how to use Terminal with this adaptor. If I could write a file that had, say, the couple most common settings (9600-8-n-1, 57600-8-n-1, et cetera) that I could simply click on, to open a new Terminal window with those settings, then simply close that, and open a new window (apple+n) in order to get back to a default settings terminal window. All feedback is most appreciated.
Thanks so much, Jason Sjobeck

Hi, Jason. Welcome to the Discussions.
You wrote: "All feedback is most appreciated."OK.
1. Have you considered discussing this with Keyspan Support?
2. Have you read the section "OSX has Terminal.app - why do I need ZTerm?" on the ZTerm Home Page? That seems to explain why one needs an app like ZTerm.
3. A quick search of Keyspan's FAQ for your product and terminal doesn't yield much more than how to find the serial ports using Terminal.
Likewise, this Google search also yields little, and variants of that search of such weren't particularly help either.
It appears your inquiry seems to be a somewhat esoteric topic.
4. Apparently, ZTerm X is a bit long in the tooth and there's no Universal Binary for it. It sounds, however, like you've tried it running on your MBP under Rosetta, yes?
5. In researching alternatives to ZTerm for you, I note the followng:• The comment from "Reverb" on this page suggests C-Kermit or Kermit as a free alternative.
• This tip on Mac OS X Hints cites Minicom as another option.6. You may want to try your question on the Unix Discussion.
Good luck!

How to use variables with

I need to get the number of lines in internal table, which would
be easy, using DESCRIBE TABLE itab LINES lines. But the problem
is, that I get the name of this internal table in the field of
another internal table, so I have to use the name of internal
table as variable, but I don't know how to use variables with
DESCRIBE TABLE (or if this is possible).

Hi,
REPORT ZPRUEBA782 .
define two tables with diferent structures.
data: begin of table1 occurs 0,
registro type i,
end of table1.
data: begin of table2 occurs 0,
registro type i,
repid like sy-repid,
end of table2.
data: rows type i.
start-of-selection.
fill them with data
do 1000 times.
table1-registro = sy-tabix.
append table1.
enddo.
do 1757 times.
table2-registro = sy-tabix.
table2-repid = sy-repid.
append table2.
enddo.
call a form that receives as input the table and returns the number
of rows as output.
perform howmanyrows tables table2 changing rows.
break-point. "evaluate the number of rows

You can try it if you don't find a better solution.

How to use the out parameter of a transformation

Hi All,
I have a requirement where I need to move all the transformations from process flows to map.SO for each transformation I need to have 1 map which calls this transformation.I have 1 transformation which has both input and output parameter.If I use this transformation in mapping then how to use the out parameter of thsi transformation.This out parameter needs to beused in other mappings.Can soemone please help me.
Thansk in advance

Hi,
I'm not quite sure what you are trying to do.
What works: Connect the outgroup of a pre- or post-mapping process operator to the mapping output parameter operator..
What does not work: Connect the outgroup of an operator that can return more than one row (e.g. table operator, filter, joiner ,...) to the mapping output parameter operator. The mapping output parameter just returns "one row", like a pl/sql function call.
You cannot pass a "data stream" from one mapping to another. Maybe the pluggable mappings is what you are looking for.

Carsten.

How to use Count with Date Parameters

Hello,
I am having issues using the Count() function in conjunction with date parameters.
This is a Siebel report and in my report I have 2 date parameters(From Date, To Date). In a nutshell I am basically trying to count Opportunities that has a start date within the given date period. However I don't see a reasonable way to put my date parameters within the Count() function. The reason being is that I need to have a huge chunk of code to convert the dates into a common format that can be compared, and it won't even fit within the code block in my rtf template. I am not even sure how to put multiple conditional statements inside a Count() function since all the examples I have seen are very simple.
Anyone have a suggestion on how to use Count() with date parameters?
Thanks.

Any chance you can get the date formats in the correct format from siebel?
I don't know Siebel - so I can't help you with that. If you get the correct format it is just
<?count(row[(FromDate>=date) and (date<=ToDate))?>
Otherwise the approach would probably need to use string function to get year/monthd/day from the date
and store it into a varialbe and compare later the same way
<?variable@incontext:from; ....?>
<?variable@incontext:to; ...?>
<?count(row[($from>=date) and (date<=$to))?>
Potentially you can use the date functions such as xdofx:to_date to do the conversion
[http://download.oracle.com/docs/cd/E12844_01/doc/bip.1013/e12187/T421739T481158.htm]
But I am not sure if they are available in your siebel implementation.
Hope that helps

How to use log4net with C# clients

Hi,
Can anybody please give an example of how to use log4net with C# clients? Foe java clients you can use the
<logging-config>
<destination>log4j</destination>
How do we use it with C# clients? Any example will be appreciated.
Thanks.
-ali

Ali,
The following is an example on how to define a custom logger (including log4net) in tangosol-coherence-override.xml for coherence .NET client; you need Coherence .NET client 3.7.1 patch 1.
<coherence xmlns="http://schemas.tangosol.com/coherence">
<logging-config>
<destination>common-logger</destination>
<logger-name>log4net</logger-name>
<severity-level>9</severity-level>
<message-format>(thread={thread}): {text}</message-format>
<character-limit>8192</character-limit>
</logging-config>
</coherence>
You also need to configure log4net in app.config. Please see the following web page for more information:

How to use assert with wireless toolkit?

Hi,
I am trying to find out how to use assert with wireless toolkit. I have found that I need to pass "-source 1.4" to the java compiler. But I can't find any documentation on how to do it.
I'm using J2ME Wireless Toolkit 2.2.
thanks
Ludde

Here's a quote from an article on Java World at http://www.javaworld.com/javaworld/jw-11-2001/jw-1109-assert.html
"To support the new assertion facility in J2SE 1.4, the Java platform adds the keyword assert to the language, an AssertionError class, and a few additional methods to java.lang.ClassLoader."
So I really think it's part of 1.4.

How to use setSoTimeOut() with socket ??

HI All!
I eagerly need to know how to use setSoTimeOut() with socket (on server side).
Actually the scenario is that My Server accepts connection and waits for connected client to send data to it. I WANT TO KEEP, IF CLIENT DOENS'T SENDS ANY DATA TO SERVER WITHIN 5 min. THEN SERVER MUST CLOSE THE CONNECTION, BUT IF SERVER RECEIVES STILL A BYTE FROM THE CLIENT WITHIN 5 mins., THE SERVER MUST RESET CHECKING TIME OUT FOR NEXT 5 MINUTES.
How can i do that??
Any help with example will be appreciated!!
Thanx in advance

you'd have to do something like this:
(this is all assuming you want to read Strings from the socket. setSoTimeout works for any read() call to the InputStream associated with the Socket)
ServerSocket ss = new ServerSocket(myPort);
Socket s = ss.accept();
s.setSoTimeout(5*60*1000); // 5 mins * 60 secs * 1000ms
BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
boolean running = true;
while(running)
try
String readIn = in.readLine();
// do whatever you want with the data read
catch(SocketTimeoutException)
running = false;
Now. That's what I think needs to be done. I don't have Java on the machine I'm currently on, so I can't test/verify it, but it goes something like that.
Good luck,
Radish21

How to use I18N with a custom validator?

This is my custom validator:
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException
        Pattern pat=Pattern.compile(".+@.+\\.[a-z]+");
        Matcher m= pat.matcher(value.toString());
        if(!m.find())
            FacesMessage message = new FacesMessage("Not a valid e-mail address");
            throw new ValidatorException(message);
    }Instead of providing the text "Not a valid e-mai address", I'd like to get the text out of my ApplicationResources property file.
How can I do this?
I know how to use it with the provided validators, but not with own custom ones
Please help me out, thanks

I found a solution for this problem, I don't know it's best practice but here it is :
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException
        String errortext;
        Pattern pat=Pattern.compile(".+@.+\\.[a-z]+");
        Matcher m= pat.matcher(value.toString());
        if(!m.find())
            ResourceBundle bundle =
            ResourceBundle.getBundle("be.vdab.resources.ApplicationResources", context.getViewRoot().getLocale());
            errortext = bundle.getString("erroremail");
            FacesMessage message = new FacesMessage(errortext);
            throw new ValidatorException(message);
    }

How to use x264 with FCPX

I used the automatic installer for x264.
There were no instructions on how to use it with FCPX or compressor.
Can someone offer a tip?
Thanks

Youn can't use it in FCP, only with Compressor. In Compressor make a new QuickTime preset or duplicate an Apple preset and change the codec to x264.
