Worklist send-xml-to-client functionality

Hi there
Quick question on wli 8.1. I have made extensive use in the past of the
send xml to client business operation in WLI 7. Is there any sort of
equivalent/how would this be achieved. Does the new worklist actually
support this kind of functionality?
Regards

A co-worker of mine got the sendxmlclient to work with the worklist web
application. It works the same way it does for the swing tasklist
application, it just wasn't in the documentation that I could find. I must
have missed a step the first time I tried it. Anyway, it appears to work.
Maybe the query.jsp you mention that the docs refer to should actually be
the setvariables.jsp.

My guess is that it's not quite there yet. As you say, message.jsp isthere
and the docs(http://e-docs.bea.com/wli/docs70/devclient/intro.htm#1052730)
refer to a query.jsp but it isn't in 7.02. We're currently using the
lightweight client sample for an equivalent mechanism but can't really
recommend this as it's deprecated and disappearing in 8.1

Struggling with Send XML to client

Hi,
I am using WL Process Integrator 2.1 with WL 6.1.
I am trying to do do an example of the "Client Call Addin Response DTD" i.e. pass
an XML document to an external java
program.
As given in docs :
http://e-docs.bea.com/wli/docs70/devclient/appa.htm#1120726
1. I have created a template definition
2. Defined a XML doc. (as per the Client Callin Request DTD) and attached to ActionSendXMLToClient
event as shown below.
<call-addin name="mywlpi.addinimpl" mode="async">
<actionid>959395846210</actionid>
<parm>itemNumber</parm>
</call-addin>
3. "mywlpi.addinimpl" is a java program I created
4. Now, the problem I run into is when I run from Worklist (Swing client program),
it errors out saying it cannot find this
class file:
ClassNotFoundException: mywlpi.AddInImpl
java.lang.ClassNotFoundException: mywlpi.AddInImpl
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
5. I have included the class file in a .jar and included in the
SVRCP of startWebLogic.cmd file. Also, when I create a Business
Operation from Studio, I can locate this Java class. So, I am
not sure what is missing. The strange part is when I run from the
Worklist JSP page, it errors out saying :
"Cannot execute this task, because it is already done." The task
is not yet done.
Is there someone who can help me here? Any suggestions
appreciated!!
Thanks,
SLN

Hi Sudhar.
I don't think your workflow will execute the next node before you mark the current
node as done. Conseqently setting the done in the decision box isn't possible.

Send XML to client: message box

Hi,
In a BPM workflow I'm putting together, I need to open a message box for information
(title, message, OK button). In the documentation, I found that I should send
an XML document to a client that looks like this:
<message-box title="title" style="information" options="ok">
<actionid>"1013679664318"</actionid>
</message-box>
Which I did: I added a "Send XML to client" action in the "True" part of a decision
node with a message-box element and its attributes, and actionid as a nested element.
When I trigger the workflow, it goes through all the expected steps but the window
does not pop up at all. I could not find the reason why anywhere. So has anyone
experienced the same problem ? If yes, how did you solve it ?
Cheers,
Yann

Send XML to Client: call-program cannot pass ampersand in parameter

In WLI Studio, I have tried to use the action "Send XML to Client" with
following information:
<call-program mode="async" name="IEXPLORE.EXE">
<actionid>1027425345078</actionid>
<parm>http://pttserver:7001/pttWebApp/Test.jsp?First=a&Second=b&Third=c</par
m>
</call-program>
The problem is that the ampersand (&) of call-program parameter will always
shift three character right on any program (e.g., IE, Notepad, etc.).
From the above example, IE can be called correctly, but its parameter -- a
string
"http://pttserver:7001/pttWebApp/Test.jsp?First=a&Second=b&Third=c", will be
passed as
"http://pttserver:7001/pttWebApp/Test.jsp?First=aSec&ond=bThi&rd=c".
I have also tried to use the string "&" instead of an ampersand, and the
parameter was passed as
"http://pttserver:7001/pttWebApp/Test.jsp?First=aamp&;Second=bamp&;Third=c".
What should be used in order to pass the ampersand character correctly?
If it is a bug, can any one suggest the workaround?
Thankyou in advance,
Suwanee Suwanapong

If you think you're encountering URL length issues make sure you are using POST and not GET, although it looks like there may be additional issues: http://www.javaworld.com/community/node/2307

Server to Rich Client sending XML over Http

I need to send XML data from a Servlet to a rich client over http.
Currently I am using HttpURLConnection and SaxTransformerFactory to do this.
Is it better to use SOAP or XML-RPC in this scenario?
Are there any good online tutorials comparing SOAP, XML-RPC and AXP-Java Net API?
What are the factors that I need to consider for choosing between these alternatives?
Please advice. Thanks in advance.

XML-RPC and SOAP use XML as a way to communicate, but they are used to invoke certain function calls in an application independend manner, not to be used to send XML data. So I'd say it depends on:
a) what do you do with the XML data?
b) will you be expanding the application?
c) how difficult is it to rework the current implementation?

Sending xml file from client to servlet

Hi,
I am writing the server component of an applcation, such that it will receive xml files from the clients(standalone application similar to javaSwing stuff but it's coded in C#), and the servlet will have to extract the data from the xml file and update the mySql database. it will also fulfill the client's request for xmlFiles (and extract data from DB, format to xml file and send back to client)
I'm new to implementing the servlet receiving files from clients so would need some help.
I've got 3 questions to ask:
1) How does the servlet receive/returns the xml file from the client as a series of httpPost request/response. Do i send a File or the file's contents as a String to/from the client?
2) Is it also a must to use socket for the file transfers? I have read in other posts about sockets as well as HttpURLConnection but i don't quite understand.
3) When I send a file back to the client(client is standalone application written in C# whereas server is coded in java), what do i specify for the HttpResponse.setContentType() in my servlet? (i'm returning the xml file to client)
Would really appreciate for any help rendered. If you have any useful links, would appreciate them too. Thanks a lot.
Karen

I've got 3 questions to ask:
1) How does the servlet receive/returns the xml file
from the client as a series of httpPost
request/response. Do i send a File or the file's
contents as a String to/from the client?The server will listen on some port for requests. The client has to open a socket to this server to send the file as string to the server.
see http://java.sun.com/docs/books/tutorial/networking/index.html

2) Is it also a must to use socket for the file
transfers? I have read in other posts about sockets as
well as HttpURLConnection but i don't quite
understand.You use HttpURLConnection to make a request using the http protocol, instead of opening a socket and then writing the html headers yourself.
3) When I send a file back to the client(client is
standalone application written in C# whereas server is
coded in java), what do i specify for the
HttpResponse.setContentType() in my servlet? (i'm
returning the xml file to client)Its up to your receiving program how to interpret this though, so you probably dont need this.

How do I Send a xml to client?

Hi friends:
It is possible to send a xml to client without a xml file in the server?
I create a Document in the server and the code is :
                                                               DocumentBuilderFactory df=DocumentBuilderFactory.newInstance();
               DocumentBuilder db=df.newDocumentBuilder();
               Document doc=db.newDocument();
               Element el=doc.createElement("root");
               doc.appendChild(el);
               Comment co=doc.createComment("This is a comment");
               el.appendChild(co);I want to write the Document to a Stream and send the XML stream to client ,so the client can display a xml.
The code is:
                                                               resp.setContentType("text/xml");
               resp.setContentLength(200);
               resp.setHeader("Content-Disposition","inline;filename=address.xml");
               ServletOutputStream so=resp.getOutputStream();
               PrintStream ps=new PrintStream(so);
               System.out.println(doc);
               ps.print(doc);
               so.flush();
               ps.close();I don't want to create a xml in the server so I can do this only use stream .But what client get is a momery address! It is org.dom.xml....@sd7fs87d What wrong with my code ? How to send the xml to client without create the xml file in server?
Thks in advanced!

Yashnoo,
What XML package that you used?
It should have a class for outputing xml
example using JDOM
XMLOutputter writer = new XMLOutputter(Format.getPrettyFormat());
OutputStream out = new FileOutputStream("dummy.txt");
writer.output(doc, out);
//this case it write to a file but in your case you can pass in ServletOutputStream
or ByteArrayOutPutStream then use method writeTo() to send it to ServletOutputStream
another thing, make sure to set your content length corretly,
resp.setContentLength(200);
how do you know its length is 200
if you are going to use ByteArrayOutPutStream, it will give you the correct length
for instance
ByteArrayOutPutStream out = new ByteArrayOutPutStream ();
XMLOutputter writer = new XMLOutputter(Format.getPrettyFormat());
writer.output(doc, out);
int len = out.size();
now you can do this
resp.setContentLength(len);
finally,
out.writeTo(resp.getOutputStream());
it should send a stream out to the client.
bottom line is, find out your package API or you can post the package you use, I can take a look
here is a sample of using JDOM to create a document then output it out to System.out
good luck
public static void createXMLFile()
          Element root = null;
          Document doc = new Document();
          try
               String[] arr = {"MainElement ","SubElement1","SubElement2","SubElement2"};
               String[] arr1 = {"MainElement ","SubElement111","SubElement22","SubElement332"};
               root = new Element("root");
               doc.setRootElement(root);
               //for each array do the following
               Element e = new Element(arr[0].trim());
               root.addContent(e);     //<MainElement>
               for (int i = 1; i < arr.length; i++)
                    e.addContent(new Element(arr.trim()));     //<SubElement1>
               //finally output to a file as your choice
               XMLOutputter writer = new XMLOutputter(Format.getPrettyFormat());
//               OutputStream out = new FileOutputStream("dummy.txt");
               writer.output(doc, System.out);
//               out.flush();
//               out.close();
          catch (Exception e)
               e.printStackTrace();

How to send XML files through Business Connector to client URL

Dear ALL
I am new to SAP BC. We have setup BC 4.8 and would like to send out a XML file from BC to Client URL. Could someone please guide me.
Please suggest solutions.
Thanks
Ahmed

Hello Mickael
Thanks for your reply. No, we do not have PI. This BC will be used for point to point communication with client.
Scenario:
R/3 server to send XML files to BC. BC will load these files ( using pub.getfile service), this file is to be parsed using pub.loaddocument service and then sent to client in XML format wrapped with digital signature. As i am new to BC i am unable to parse this file and wrap it with the digital signaature to send it.
Kindly advise on how best can we perform this action.
Thanks

Also, in below link, you can ignore XI specific part and observe how its sending XML to external URL:-
(I know it describes call to SAP XI server's URL, but it can be used to call any URL)

In addition to all above, following configs to be present at ABAP application server: -
1. The hostname used to URL should be present in SAP ABAP application server's 'hosts' file.
2. Security certificate (if available) for URL to be called must be installed in SAP ABAP application server.
Let me know if you achieve any progress with it...

Client function works once and then cannot be found

Hi all,
I am having a strange problem where:
1) A flash client successfully connects to FMIS and successfully makes a nc.call command and receives a response.
2) You can then send in a call to the server with: nc.call("startRecording", myResponder);
-- The recording starts, I get my updateState command fired off (via broadcastMsg) to the client and everything seems fine...
3) But when I call: nc.call("stopRecording", myResponder);
-- The recording stops as it should, and there are no errors on the server side... but, I get the following output on the client:

Relative file pathnames in FM book files
This, by the way, is not a bug.
It's an intractable consequence of the dissonance between Unix-like (common root) and DOS-like (multiple root / logical drive) file systems.
Newer versions of Frame may have an "archive" capability to save out a complete book with restructured fs hierarchy. Aftermarket products exist for older versions. We wrote our own archive script for translation export, that even gathers the imports.
Of course, when you are the recipient of some random .book, archiving was almost never done by the exporter .

Sending xml over http

I have a WLS 6.0 servlet that receives XML transactions via a post method.
          Code snippet as follows:
          public void doPost(HttpServletRequest req, HttpServletResponse res)
          throws ServletException, IOException
          int txContentLength = req.getContentLength();
          //get entire input xml stream and store in a stringbuffer
          InputStream inp = req.getInputStream();
          BufferedReader br = new BufferedReader(new InputStreamReader(inp));
          byte[] ba = new byte[txContentLength];
          System.out.println("Reading...");
          int bytesRead = inp.read(ba);
          System.out.println("bytesRead= " + bytesRead);
          while(bytesRead < txContentLength) {
          int moreRead = inp.read(ba, bytesRead, (ba.length - bytesRead));
          if(moreRead == -1)
          break;
          bytesRead += moreRead;
          System.out.println("finished reading buffer...");
          StringBuffer sb = new StringBuffer(new String(ba));
          I have a java client on my PC that takes an XML file as input and sends the
          information to the servlet without any problems.
          The problem is a client that is connecting to our network via a T1
          connection. When they send transactions, about 1 out of every 4
          transactions makes it past the "Reading..." statement above. The other
          transactions appear to 'hang' when it hits the inp.read(ba) line above.
          From all indications, that servlet's execute thread appears 'hung' as if the
          inp.read() is waiting forever.
          I've tried using readLine() on the InputStream() and my local client program
          is unaffected - it works OK. The remote client is having problems using
          either method. The only difference I've noted with the remote client is
          that they are using HTTP 1.0 and I'm using HTTP 1.1. Initially, their
          mime-type was null but they've changed it to text/xml and no luck. I've
          even sent them my client code that is working and they are still having
          problems...
          Another strange anomoly is that req.getContentLength() is returning a valid
          number on the transactions that fail. For example, I had some debug code
          that showed the content length and it was always something like 4012 or
          3500, etc. Not -1 as I would expect...
          Has anyone run into this problem with receiving XML transactions?
          Thanks
          Rob Mason


Thanks for the suggestion - I went back and added a check on the
          contentLength to make sure it had a valid number before trying to call any
          'read' methods... still no luck.
          I did go in and put a try/catch around the read() logic below. The
          exception thrown is an InterruptedIOException. The docs say that this is
          thrown 'to indicate that an input or output transfer has been terminated
          because the thread performing it was terminated.'
          This would seem to indicate that WLS is having the problem - not the client?
          Via the console, under the Configuration section, my HTTP section has the
          following values:
          POST timeout secs: 10
          Max POST time: 10
          Max POST size: -1
          Is there anything else I can try on the server level?
          Thanks

How to send XML file into XI using sender HTTP adapter

I am using HTTP sender adapter to post the XML file into XI. I tried to form the URL by using the following String query , but I am unable to execute file.
String urlString = "http://<servername:portno>/sap/xi/adapter_plain?namespace=<namespace>&interface=<interface name>&service=<service name>&party=&agency=&scheme=&QOS=BE&sap-user=xiappluser&sap-password=satyam&sap-client=100&sap-language=EN";
How can I execute xml file by using HTTP sender adapter.
Any one with better suggestions, about this idea?
Thanks in advance for all.
Ram Raj

Hi
Just use the following parameter to send xml file using HTTP adapter.
"http://xiserver:8000/sap/xi/adapter_plain?namespace="senderNamespace"&interface=senderinterface&service=sender service";
"&party=sender party"&agency=&scheme=&QOS=BE&sap-user=userid &sap-password=password&sap-client=100&sap-language=D";
with the help of this you are able to point out which interface you would like to use.
And in payload pass the xml.
and thats it
carry on
Cheers
Regards
Piyush
