Exception In getting Response from Databse ..

Hi friends,
I am getting a very unusual problem.I have a Webdynpro application which is using WebService Model.
It usually works fine, but whenever I am restarting the server. My application throws an null pointer exception, whenever there is a ejbFinder method call.
And when I stop and start the application again from Administrator Console, than again it starts working fine.
Kindly suggest me some way, So that i don't have to perform this activity again and again.
Thanks and Regards
Yajush Mishra

It is likely your application is starting too quickly or has a soft dependency rather than a hard to something it needs. I would read up about these in the J2EE developers guide and put a dependency in your app to one of the last appications to start and that way it starts late in the deployment. You can see when apps start in the logviewer... I think it is the server log

How to get response from an asynchronous BPEL process in Java

I'm experimenting with BPEL and doesn't seem to be able to get response from an asynchronous BPEL process. Here's the deal:
I have a BPEL process that takes a string as input, and gives another string as output. This is a asyncronous process.
I want to initiate this BPEL process as a web service so I generate a Webservice Proxy in JDeveloper 10g (10.1.3.0.4). The function to call the process is now called "initiate" and takes three arguments: the input string, a "org.xmlsoap.schemas.ws._2003._03.addressing.EndpointReferenceType replyTo" and a
"org.xmlsoap.schemas.ws._2003._03.addressing.AttributedURI messageID".
HTTP-Analyzer shows that invoking the BPEL process with initiate("somestring", null, null) results in sending a SOAP message to the BPEL process, which returns a "202 Accepted". How do I get the response from the process? My intuition tells me that I have to use that second argument, that EnpointReferenceType thing. How do I use that?
Another question: If a asynchronous BPEL process does not exists (so the endpoint does not exist) the Java proxy does not throw an error when runned. It does not even sends a message. It exits with status 0! (This happens for example when deploying a new version of a process and when the "old" version is undeployed). Calling a non-existing synchronous BPEL process, the Java proxy DOES throw an error.

Clemens,
That all sounds logical. But somehow it is still a mystery for me ... Somehow I don't see what should be done.
To call the async BPEL process I have the following procedure:
initiate(String input, org.xmlsoap.schemas.ws._2003._03.addressing.EndpointReferenceType replyTo, org.xmlsoap.schemas.ws._2003._03.addressing.AttributedURI messageID)
The first argument is the input for my BPEL process. The second is the address to a webservice that should handle the callback, right? The third is a messageID (makes sense, but why of the type AttributedURI?).
Here lies my problem. It is not clear to me how these EndpointReferenceType & AttributedURI work. I can't find anything on the net about it. The AXIS examples as where mentioned earlier use other types (namely the "org.xmlsoap.schemas.ws.addressing.MessageID" and "org.xmlsoap.schemas.ws.addressing.ReplyTo") which are completely different.
What I did so far:
- I created an webservice proxy that listens on the onResult endpoint of the BPEL process.
- I created an webservice proxy that calls the BPEL process through the initiate procedure, but it is not completely clear to me how to construct the EndPointreferenceType replyTo, and the MessageID. I did something like this:
EndpointReferenceType replyTo = new EndpointReferenceType();
// callback service running on local machine
// This URI class is the java.net's version
URI replyToURI = new URI("http://vaccinatie:8988/syncro-callback-context-root/stringconcatCallbackBindingPort");
// This AttributedURI is the org.xmlsoap.schemas.ws._2003._03.addressing's version
AttributedURI address = new AttributedURI();
// the only public methos that made sense to me:
address.set_value(replyToURI);
replyTo.setAddress(address);
// call the BPEL process
myPort.initiate("test123", replyTo, address);
But the above doesn't work (largely because I don't know what I'm doing here prob.:-) ) It does send the "test123" message, and the BPEL process does process it, but I don't seem to get the callback right.
I hope this makes my problems somewhat clearer. I hope someone can help me, because I'm just a beginner in this whole "web service area" and seems to do something terribly wrong here, because it should be very simple. Thx.

Not getting Response from RFC

Hi,
I am doing RFC to File. I could generate the FILE successfully. But I am not getting Response from RFC. I am getting empty payload. I am doing with out BPM. I did succesfully File-RFC-File. but here RFC is the sender. I have some doubts in defining Interface mapping and Message Mapping. Is this a Syscronous scenario by default ?
If I want to get the resonse of RFC to a file. How many Receivers and Senders do i need to create?
Regards,
Varun
Edited by: Varun on Sep 9, 2008 1:00 PM

hi,
Map Rfc.response to the File; hence rfc sender adapter and file receiver adapter..one sender n 1 receiver.Remember:
1. In the report that makes the call to XI , make sure that you use call RFC in a background task.
2. Make sure you use Commit Work at the end of the report.
Follow:
Send RFC to SAP XI Asynchronous
Also pls visit
Re: RFC to FILE
for the same scenario.
Thanks,

Watched folder error - "Exception while getting principal from Directory manager"

Hi! I've been having problems with a LiveCycle ES installation.
I've configured a watched folder that starts a process with an Office
Document, converts it to PDF and applies a Rights Management Policy.
It runs on behalf of an Active Directory user.
Sometimes it works flawlessly, but most of the time it fails, giving a
ridiculously long failure log with the longest trace stacks I've ever
seen in life... resumed:

I vaguely suspect is the server's clock going out of sync with the domain controller's clock, but I tried everything I knew of about it with no consistent results.
It's LiveCycle 8.0.1 SP2 installed on a Windows 2003 Server.
Manual install, JBoss Clustered configuration (the second node is actually turned off for the time being)
SQL Server 2005 as backend Database
Users on Active Directory on a Windows 2003 Server -which is a "copy" of the main domain controller.
Watched folder is in a mounted share of another Windows 2003 Server acting as fileserver.
Any clue will be greatly appreciated!!

Hello,
sorry in advance for my english. i am beginning in Adobe LiveCycle and i think that you can help me : i want to configure a watched folder to automatically convert in pdf file and apply a right management policy. Can you tell me how you configure it ? many thanks in advance. regards

Why im getting too long time in getting response from server in RMI???

I'm using RMI architecture. On my server side I put this method getRubricHierarchy() which returns the ArrayList of Test class objects. everything is working properly fine.
Im getting response properly, problem is its taking very long time in getting the response. method populate and create ArrayList in 0 second at server side but its taking more than 20 seconds to get response at client side.
My arraylist size is 30,000.
Any suggestions to reduce the time.
below you can see the code.
public List<Test> getRubricHierarchy(String strTree,String gblCombinedRepSectionID,String gblCompleteRepSectionID,String gblCompleteRepertoryID,Map authMap) {

You have an O(N**2) algorithm at the end that is rather ill-considered. It seems to me at first glance that it could be combined int the previous loop.

Socket Programming-Not getting response from server.

Hi,
I am trying to communicate with server using java socket programming, I am getting the response for first two times third time when I am trying to write some thing I am not getting any response from the server,
I am writing to migrate the vb code to Java the vb is using a c++ dll to communicate with the server and we tried accessing the dll from java using JNI then it is working fine, this dll is dependent on windows so we want to avoid the dependency with windows that is why we are going for socket programming, Please help on this.

Hi,
I am writing the data in forms of string
like
Socket sockt = new Socket(ipAddress, portNo);
out= new DataOutputStream(sockt.getOutputStream());
in = new DataInputStream(sockt.getInputStream());
out.writeBytes("Serv");
out.writeBytes("Serv,32");
out.writeBytes("home,serv32,run.prg,sucess");
these are the strings to communicate with server.
I am trying to read the same
StringBuffer buf = new StringBuffer();
          byte b = '\0';
                    try {
               while ((b = in.readByte()) != '\0')
                    char ch = (char) b;
                    buf.append(ch);
          } catch (Exception e) {
               System.out.println(e.getStackTrace());
we are getting the response for the first two strings, but for the third string it is getting stucked for some time and returing some junk values like '???' we are sending the same string using JNI and it is working.

One socket and two ports, not getting response from the server

Hi everyone,
I am working on device which communicate through Tcp sockets, It has an IP address and one port for listening and another for sending the response.
Problem is that I am able to create a connection to Device ip+port, and i am trying to listen on the same port while the device is sending the response on other port. My problem is that i can't create another socket using this port and therefore not getting the response from the device.
Can you people tell me how to handle such socket communication in java ?
Thanks in advance.

I am working on device which communicate through Tcp sockets, It has an IP address and one port for listening and another for sending the response.Are you sure? That's not usual. It would be usual for it to use the same port for listening, reading, and writing.
Problem is that I am able to create a connection to Device ip+port, and i am trying to listen on the same port while the device is sending the response on other port.I would try just reading from the same socket you are sending on. I suggest you have misunderstood how the device works.

Getting response from a server

im working on a simple smtp mail sender and i want to get responses to the commands that i post to the DataOutputStream. in all examples on java.sun.com and the net, there is a while block used for reading response from the server.
while((c=is.read()) != -1)
sb.append((char)c);
this code did not work on my application, i changed a bit like below:
/**Get a response from server */
private String getResponse() throws IOException {
int CR = 0, LF = 0;
int c;
char ch;
int count = 0;
StringBuffer sb = new StringBuffer();
while (true) {
c = is.read();
count++;
ch = (char) c;
if (c == -1) {
break;
else if (ch == '\r') {
CR = count;
else if (ch == '\n') {
LF = count;
if (LF - 1 == CR) { //CRLF seen
sb.append(ch);
break;
sb.append(ch);
return sb.toString();
and i use this function in my code as
os.write( ("QUIT\r\n").getBytes());
System.out.println("QUIT : " + getResponse());
this works, because it returns a single line that has a CRLF at the and of line, but if i want to read multi-line responses like greeting messages, i tried to change the code as on the examples like:
/**Get a response from server */
private String getResponse() throws IOException {
int c;
StringBuffer sb = new StringBuffer();
while((c=is.read()) != -1)
sb.append((char)c);
return sb.toString();
this code does not work, because i cannot reach the end of stream. i want to post one command and get one response for that command.
how an algorithm i can develop to solve this problem?
thanks for all help.

i changed the code and it's working well now:
/**Get a response from server */
private String getResponse() throws IOException {
int c;
if((c=is.read()) != -1) {
byte[] b = new byte[is.available()];
StringBuffer sb = new StringBuffer();
is.read(b);
sb.append((char)c);
for(int i=0; i<b.length; i++) {
sb.append((char)b);
return sb.toString();
return "";
if you directly use is.available() when there is no response currently available, it returns 0. we wait for the first character of server response, and then use is.available(). thanks to Kay_Kadner for the idea.
(im a newbie, and dont know how to convert byte[] to String, tried b.toString() but only got meaningless values)

Not getting response from Client Proxy

Hi,
We are developing a scenario - File->PI->Proxy using ABAP Proxies.We are posting a file thru PI 7.0 to R/3 .In R/3 the server proxy(Inbound Asynchronous) will receive the message and BAPI will be called. The response from the BAPI will be reaching the server proxy and passed to the client proxy(Outbound Asynchronous).
Server Proxy(request) --> BAPI --> Server Proxy(response) --> Client Proxy(response)
The response from the client proxy has to be send to PI and a file will be generated as the output.
Can anyone provide me suggestions to call client proxy from a server proxy by passing the response message to client proxy???
Thanks in advance.
Regards,
Dibyajyoti

Hi,
I hope, you are done till the Implementation of Server Proxy, where you are calling a Bapi and passing the Input variables the Interface received and BAPI is giving a response back.
Now your question, how to send the response back Asynchronously.
I think, you have to do the same, what you do for a client proxy and at last call the method EXECUTE_ASYNCHRONOUS before the Final Commit Staement. I think this should work.
But using Synchronous Interface in such cases is always a handy and easier option.

Getting response from a Web Service

Hello, everyone,
I want MII to show the response from a Web Service it is calling through the Web Service action.
But when this Web Service return an error (as a Soap Fault response), MII simply does not show the response. It show it truncated, such as
"<?xml version="1.0" encoding="UTF-8"?>
<ReceiveMessageFromMESResponse xmlns="http://tempuri.org/"/>"
It prevents me from showing the error message to the user.
What can I do to have MII show me the complete response received from the called Web Servce?
Thanks in advance!

Hi, SB!
Yes, this would solve the problem, but it would require changes on already-implemented, working external Web Services, which should be avoided by all means.
SOAP Fault responses are part of the SOAP protocol. I expected MII to understand it.
Thanks a lot for your answer!

How to get response from financial department

How do I get someone in financial to review an account that has bad information in it ? Someone at Verizon has mistakenly used ACH (Bank) information and entered it as debit card information. When they tried to post to it, of course it failed. As a result I am now on COD cash only for the duration of my contract. No person in their financial division or in the regular customer service can seem to correct this. Any suggestions ?

Update - I began a complaint with the BBB.
I also called Verizon again as suggested, and asked for a supervisor again after explaining the situation. For the first time I spoke with someone who not only understood the problem but fixed it by changing the status of my account from cash only to auto payment.
I received a call from an 'Executive correspondent' at Verizon regarding my complaint to the BBB. I related the entire story to her, after which she apologized and assured me she would look into why the original person I spoke with in financial services was unwilling to help, and that the assistant manager at the local store was unable to get help either. I implied that their customer service left a lot to be desired in its present form and, I agreed with her that some investigating needed to be done.
I also asked why Verizon was unable to verify billing information before the actual transaction, as is done by many other corporations - Paypal being one. They will do a small (between .01 and .15) transfer then transfer it back. She informed me that Verizon had made a corporate decision not to do this as it would 'confuse' their customers. I disagree - their current system puts the entire responsibility for any errors on their customer. She confirmed that I had provided the correct information initially and had no explanation for how things turned out as they did.

WorkFlow BADI : Get Responsi From R/3 for given WBS

Hi,
Scenario:
I am developing a Workflow BADI in SRM5.0.
For all cost centers I am getting approvers based on Z-table values.
But then for WBS... i have to get the list of approvers from R/3.
I created a Function module in R/3 dev which gets me Responsible person.
Issue:
While calling the RFC function module... by giving destination name, the Function module is working fine.
But I dont want to Hardcode Destination name.
Can I get the Destination name in some other manner ?
Helpful Answers will be rewarded.
Regards,
Ashwin.

Hi,
Please follow this logic:
1) Function Module BBP_GET_BACKEND_SYSTEMS will provide you the backend system detail (logical system name).
2) Then use the FM BBP_LOGICAL_SYSTEM_GETDETAIL to get the RFC destination of the backend system which can be used to make teh RFC call.
This would avoid hard coding and will work fine.
Sample Code:
*& Report ZKB_BACKEND_SYS
REPORT zkb_backend_sys.
DATA: lt_log_sys     TYPE TABLE OF bbps_logical_system.
DATA: lt_messages    TYPE TABLE OF balmi.
DATA: ls_log_sys     TYPE bbps_logical_system.
DATA: lv_destination TYPE rfcdest.
CALL FUNCTION 'BBP_GET_BACKEND_SYSTEMS'
TABLES
    et_logical_systems = lt_log_sys
    et_messages        = lt_messages.
CLEAR ls_log_sys.
READ TABLE lt_log_sys INTO ls_log_sys INDEX 1.
CHECK sy-subrc EQ 0.
CALL FUNCTION 'BBP_LOGICAL_SYSTEM_GETDETAIL'
EXPORTING
    logical_system = ls_log_sys-logsys
IMPORTING
    destination    = lv_destination
EXCEPTIONS
    not_found      = 1
    OTHERS         = 2.
IF sy-subrc <> 0.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
          WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
WRITE:/ 'RFC Destination is:', lv_destination.

Getting response from Database by sending in parameters

Hi,
I am providing parameter which supplies string values to query the database using adapter. I can see the invoke activity sending the string value to the database, but respnse message does not contain anthing.
Can someone please tell me how to retrieve records from database by suplying parmeter value?
Thank You
Anil

hi Anil,
use a simple stored procedure or pl/sql function and specify the input and output parameters. We can send any no of parameters to a function and a function can able to return a value. so you can achieve your requirement using pl/sql functions. Learn about that more.
when you will define ParterLink (using DBAdapter browing databse to select your function ), you shud be able to view one OUT parameter with datatype what you have mentioned earlier in pl/sql function. When you define Invoke for that Parterlink, you should get Invoke Output variable with output variable (having name of that function.)
If you cannot browse the function in your DB Adapter, just make sure that the user you have defined in DB Adapter has enough privileges to access that function.
