Hi Mudit,
I tried the code as advanced UDF but it gave me
Source code has syntax error:

Same filename from a sender to receiver :: DO we really need UDF ?

Hi
This is in refrence of Weblog " same filename from a sender to a receiver file adapter " by Michal Krawczyk.
/people/michal.krawczyk2/blog/2005/11/10/xi-the-same-filename-from-a-sender-to-a-receiver-file-adapter--sp14
Actually I worked on another weblog by " Shabarish Vijayakumar "-->
/people/shabarish.vijayakumar/blog/2006/04/03/xi-in-the-role-of-a-ftp
And I am getting file created on the receiver side with the same file name as on the sender side without using the user-defined function mentioned in Michal's weblog.
Now my question do we really need UDF for same file name when on the sender we are polling for one file only by its name.
I am not exaclty getting the benefit of this feature. Can you tell me why do we need this feature as in whatever scenarios I worked I mentioned the file names in both Sender & Receiver File Adapters.
So I am not getting what is the use of using this UDF, when we mention the name of file needs to be created on Receiver side.

Hi
I put this code for UDF -->
String valueNew;
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String valueOld = conf.get(key);
if (valueOld != null)
valueNew = valueOld.replaceAll("input123",name);
conf.put(key, valueNew);
return valueNew;
Signature of UDF is this :: public String GetFileName(String name,Container container)
But when I am testing this UDF, I am getting following RunTime exception -->
Runtime exception during processing target field mapping /ns0:FileFTP_InOut_MT/File_nm. The message is: Exception:[java.lang.NullPointerException] in class com.sap.xi.tf._FileFTP_MsgMapping_UDF_ method GetFileName$[lalit, com.sap.aii.mappingtool.tf3.rt.Context@735df3b0] com.sap.aii.mappingtool.tf3.MessageMappingException: Runtime exception during processing target field mapping /ns0:FileFTP_InOut_MT/File_nm.

Need help with getResource() problem under weblogic 6.1

Hey all,
 I've got a serious problem that I can't figure out. This should be really
 simple - but it's alluding me. I have an ear file with a number of servlets
 inside it. This ear file also contains a resource that my servlets want to
 read from. This resource is located (within the ear file) at:
 "/content/structure/a.txt". The file contains raw ascii.
 To have my serlvet read from this file, I thought it would be as simple as:
 URL content =
 servlet.getServletContext().getResource("/content/structure/a.txt");
 // pw is an instance of PrintWriter
 pw.print(content.getContent());
 However, when I execute the above I get the following exception:
 java.lang.NullPointerException
 at
 java.net.URLConnection.stripOffParameters(URLConnection.java:1011)
 at java.net.URLConnection.getContentHandler(URLConnection.java:979)
 at java.net.URLConnection.getContent(URLConnection.java:581)
 OK, so fine - I figure that I'm new to this. The documentation for the URL
 class tells me there is another way around this. It says that rather then
 calling getContent() directly, I can open a stream on the URL and read from
 that, like so:
 URL content =
 servlet.getServletContext().getResource("/content/structure/scenario2resourc
 es.txt");
 FileInputStream fis = content.openStream();
 but when I do this I get the following different exception:
 java.lang.ClassCastException: weblogic.utils.zip.SafeZipFileInputStream^M
 at Utility.writeFileToOutput(Utility.java:134)^M
 Apparently this thing is trying to return a web-logic-specific stream (which
 is incompatible with an FileInputStream) - which I don't want to use or
 learn about since I want my stuff to work under other webservers.
 Can anyone tell me what I'm doing wrong? This should be simple.

Wenjin,
 I appreciate your response. I tried treating it as a normal InputStream -
 but it didn't make any difference. Here's what I did:
 URL content =
 servlet.getServletContext().getResource("/content/structure/scenario2resourc
 es.txt");
 InputStream is = (InputStream)content.getContent();
 And here's the exception:
 java.lang.NullPointerException^M
 at
 java.net.URLConnection.stripOffParameters(URLConnection.java:1011)^M
 at
 java.net.URLConnection.getContentHandler(URLConnection.java:979)^M
 at java.net.URLConnection.getContent(URLConnection.java:554)^M
 at java.net.URL.getContent(URL.java:807)^M
 at Utility.writeFileToOutput(Utility.java:134)^M
 You can see that it is definitely breaking somewhere in getContent().
 If you have any other ideas, I'd appreciate hearing about them.

What needs to be changed to run Weblogic as a service and not as an application?

The server is running Windows 2000. Weblogic was installed on the server as an
application and not as a service. We need Weblogic to run as a service, could
someone please provide me with information on the easiest way of doing this, as
we can not re-install the Weblogic at this point. Any assistance would be greatly
appreciated.

Mapping issue, maybe need UDF

Hi Gurus,
I am having a source message like this:
ITEM (1..unbounded)
>SOURCEFIELD (1..1)
Sourcefield is below Item.
In the target side, there is a field called TARGETFIELD (1..unbounded) that needs to be created with next condition:
for each nonrepeteable sourcefield value, one targetfield must be created. For example:
<Item>
 <Sourcefield>1</Sourcefield>
</Item>
<Item>
 <Sourcefield>1</Sourcefield>
</Item>
<Item>
 <Sourcefield>2</Sourcefield>
</Item>
<Item>
 <Sourcefield>2</Sourcefield>
</Item>
<Item>
 <Sourcefield>3</Sourcefield>
</Item>
In this example, 3 TARGETFIELD must be created, since there are only 3 non repeteable values (1, 2 and 3).
Something important to notice is that values will ALWAYS come sorted.
How can I do this in mapping? Should I develop an UDF? Or can I use PI's common functions?
Thanks!
Edited by: chapa_akd on Mar 31, 2011 12:18 AM

Hi,
You can use
Source Segment -
>Removecontext-->Splitby value(Value Change)--
>Target Segment
and
Source Field--->Removecontext>Splitby value(Each Value)--
>Target Field

I need the server run time for weblogic server. Please help

Hi ^^,
I am trying to create a web project in Eclipse WTP europa. I do not have the bea weblogic server installed on my desktop. My organization has issues running it locally. I need to first create a project and then create a war and then deploy it on server.
I am going through the tutorial at the following website:
http://www.eclipse.org/webtools/community/tutorials/BuildJ2EEWebApp/BuildJ2EEWebApp.html
It says "To do this tutorial you will need a server runtime that is supported by WTP"
Also "During web application development, we will need a server runtime environment to test, debug and run our project".
Hence I need the link where I can download the server runtime for bea weblogic server.
I have tried to download the tomcat runtime from the following location:
http://apr.apache.org/download.cgi
But tomcat is not accepting it as a server runtime, pls help...

Need UDF for concatnating three fields

hi all,
 need java coding concatnating three fields , please help me as i dont know java
thanking you

Hi Sridhar,
use following code
public void calculate(String[] var1, ResultList result, String[] var2, String[] var3, String[] var4, String[] var5, String[] var6, String[] var7, String[] var8, String[] var9, String[] var10, String[] var11, Container container) throws StreamTransformationException{
for(int i = 0 ; i < var1.length;i++)
 if (var1.equals("true"))
 result.addValue(var11+ var2var3var4var5var6var7var8var9var10);
else
result.addValue(ResultList.SUPPRESS);
while creating this UDF:
Select Execution Type as "All values of Queue" (you will see this option when you go for creating UDF)
In signature Variable Declare 11 variable 1st will hold true or false and rest will be for concatination
First input is output of comaparison ("WE")
Now var1 will hold the output of comaparison. if it is true it will concate 10 value if false it will pass suppress (Same as if withoutelse)

Message mapping problem / experts needed / UDF?

Hello experts,
I have the following problem in a message mapping:
Source structure is as follows:
- Node a (min 1, max 999)
- Subnode b (min 0, max 999)
- Each Subnode b has the element "number" (1,1)
This structure must be mapped to the following target structure:
- Node c (1,999)
 - Subnode d (0,999)
 - Each subnode d has the following elements:
 - e1
 - e2
 - e3
 - e11
1 Source node a should create 1 target node c.
All numbers in all subnodes b of one source node a should be mapped to the e1, e2,...e11 elements of the target structure. As one target node d can only contain up to eleven numbers, there must be several d nodes.
I have already tried to create a UDF, but it does not work.
Any experts who would like to share their knowledge?
Thanks in advance.
CHRISTOPH
Edited by: Christoph G. on Apr 23, 2008 10:46 PM

Hello again,
meanwhile I have worked hard on it and I have found the solution (just one UDF (queue function) which gets the article numbers as well as constant(targetField). So the UDF covers the creation of the "groups" as well as the mapping of the article numbers.
It was really interesting and it made me ambitious to find the solution myself I do not have access to the system today, but I will post my solution as far as I have access again. Maybe you still want to search for a solution? It really may be fun, just like some kind of a puzzle game.
In order to make it more clear, here comes the source and target structure with an example. Let me once more explain it: In the source, there are positions, each with unlimited article numbers. Each position will create a targetPosition. The node "targetPosition" has the subNode "articlenrs" (unbounded). Articlenrs has 11 differnet elements, calles a1, a2, a3, ..., a11. That means, all article numbers from a source postion should be mapped to "groups of 11 target article numbers". Please be aware the there are 11 differnet target fields for article numbers: a1, a2, ... a11.
I think that' why the solution of Liang Ji and Rohit Kalugade will not work...
SOURCE
<position>
 <articlenr> 123 </articlenr>
 <articlenr> 456 </articlenr>
 <articlenr> 4783 </articlenr>
 <articlenr> 123 </articlenr>
 <articlenr> 456 </articlenr>
 <articlenr> 4783 </articlenr>
 <articlenr> 123 </articlenr>
 <articlenr> 456 </articlenr>
 <articlenr> 4783 </articlenr>
 <articlenr> 123 </articlenr>
 <articlenr> 496 </articlenr>
 <articlenr> 4783 </articlenr>
 . (unbounded)
</positon>
<position>
 <articlenr> 543 </articlenr>
 <articlenr> 865 </articlenr>
 <articlenr> 643 </articlenr>
</positon>
TARGET
<targetPosition>
<articlenrs>
 <a1> 123 </a1>
 <a2> 456 </a2>
 <a3> 4783 </a3>
 <a11> 496 </a11>
<articlenrs>
<articlenrs>
 <a1>4783 </a1>
</articlenrs>

<targetPosition>
 <articlenrs>

Need help regarding certification alternative to weblogic portal developnme

Hi All,
I was planning to give weblogic portal certification (1z0-110).
But I found that the 1z0-110 certification is retired.
Can anybody guide me to some other alternative.
I am a JAVA developer who is interested in doing some server certification. I am not going for admin certification because I think that will not help me as a JAVA developer.
Thanks in advance

Help Needed with wlst distributeApplication and deploy weblogic 10x

Looking for help on missing steps...
Trying to distribute an application .war from one host (adminServer host) to all cluster members.
I first distribute the app which appears to work:
PackagePath = '/opt/wls/domain1/deploy/app1.war
clusterName= 'SomeCluster'
myapp = 'app1'
distributeApplication(PackagePath, targets=clusterName)
I then execute a deploy cmd, pointing to where the distributed application should be on each host:
deploy(myapp, PackagePath, targets=clusterName)
At this point everything completes without error, but on the admin Server console I see two deploys now for app1:
1. app1 is deployed and active
2. app1.war is deployed in Prepared state with the status as distribute Defferred.
Im guessing #2 is there from the distributeApplication call... how do I deploy the app after executing the distributeApplication call?
Thanks
Edited by: user9253444 on Jul 29, 2010 5:29 AM

Ok, so it looks like I only need to call a startapplicaiton after the distribute to make this work.
