Error getting response from Webservice
Hi
I created a webservice from a WSDL file and deployed it to my weblogic 10.3
Now when I invoke the webservice from my weblogic test client, I get the following as the response.

It is not finding the correct URL - hence the 404 - page not found error.
Correct the URL and try again.

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. -
Response from webservice needs to send as Mail content
Hello,
i have to configure a scenario as given below
IDOC --> JDBC --> WebService and response from WebService to SMTPmail receiver.
now i got strucked at Webservice response. after i got the response from WebService(SOAP), i need to send the both Request and response to Mail Receiver. So Please let me know how to capture request and response both to my SMTPmail adapter(as content or attachment).let me know the steps to proceed for SMTPmail Receiver
Regards,SARANHi Raj,
Thanks for teh reply.
i have already configured teh above mentioned scenario.but i am not able to get Request and response.
Could you pelase provide teh steps how to configure BPM in this scenario..(as ia m not handson with BPM)

Hi, well i read file and want to send data to WS while getting info back, that data is transmitted. But because it should be synchronous i don't get any response from WS.
What might be wrong?! even if the WS would answer, there should be an entry in Monitor!?
brUr sender is file which could not be sync. If u want to get the response from webservice, then u need to configure Async-Sync bridge using BPM.
Regrads,

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 PMhi,
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,

How to refresh AdvancedDataGrid in flashbuilder 4, getting data from webservice
I have tried many things like below to get my grid updated when it gets data from webservice ,
myGridName.ValidateNow(),
myGridName.InvalidateList(),
if(myGridName.updateCompletePendingFlag)
the problem is I have two buttons that can show hourly, and daily data in one grid, when activating daily button, I got the data in the grid but with delay of maybe 2 to 5 seconds(to get data from webservice) and within this period if user clicks on hourly button, to see the hourly data, then user will see the daily data attached to the end of the hourly data in the grid, please notice that there is just one grid. the problem is I don't know how much to wait for the first set of data to show up on the grid (daily data) and then enable all other buttons so user can only just choose Hour button when all the daily data has been shown in the grid, so when user click on hour button, the daily data will not attached to the end of hourly data in the grid.
any help is appreciatedThanks for the answer,
I do disable other controls when one of the buttons are clicked and waiting for the data, and in my retrieved data function from webserver , at the very end after I retrievd all the data from webserver and add it to the dataprovider of the grid, I enable all the controls, but the problem is in reality , I see that all other controls are enabled sooner than I see the data show on the grid, and because of that user can think there is no data in the grid and click on the hour buttons , causing that the daily data to be attached to the hourly data in one grid.
I appreicate if you could still help me -
Error - no response from the server
Attempting to upload my first file (18,888 KB) to the acrobat.com server with this consistent error message:
"Error: Acrobat did not get a response from the server. Try again later or contact your system administrator." When I cancel the message after a retry, the following message appears: "The following files were not uploaded due to an unknown error."
Support yesterday indicated to restart my machine - same result. A bit desperate to get this up and running since I like the whole concept of sharing and presenting technical information. Help!
CharlesDid you ever figure out a solution to this problem? I am getting the same message and can't figure out how to fix it. Thanks!

Error "No Response from Application Web Server"
Hi folks,
When i'm trying to access the database through grid contorl... i'm getting the following error... Any ideas to resolve it?
No Response from Application Web Server
There was no response from the application web server for the page you requested.
Please notify the site's webmaster and try your request again later.Hello,
Is it possible that not all of your iAS services are started ?
Try to run $ORACLE_HOME/opmn/bin/opmnctl status -l
to see if for example the Http server process is down...
If it is down, then restart it up with the command :
opmnctl startproc ias-component=HTTP_Server
(same for any other mid-tier process).
Hope this can help you.

Proxy error - Invalid response from upstream server
We are using Oracle Application Express Listener for requests between a Web browser and Oracle Application Express engine.
Tomcat and Java version on the web server (Windows 2008):
TomCat v 6.0
Java version "1.6.0_25"
Application Express version - 4.0.2.00.07
Access to APEX site happens via Reverse Proxy.
One of the reports is giving following error message from past few days and there are no log entries in Tomcat server.
Proxy Error+
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /appname/f.
Reason: Error reading from remote server
What could be possible reasons for this proxy error? Please help with the possible solutions to this problem.
I have tried restarting Tomcat service, used different browsers, cleared browser cache but for no avail. Error is only on one particular report page.Hi,
Have you tried to access the page directly via tomcat without the reverse proxy? This way you can determine if the problem arises at the reverse proxy or tomcat.
You say it happens only on 1 specific report page, this makes me think there is something with that page and not with the reverse proxy or tomcat. Arises the error when you access the page directly or via a menu option? Maybe the menu link is not correct otherwise i suggest that you take a good look at that page.

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. -
How to update the Sent Idoc Status based on the Response From Webservice
Hi All,
I have to develop Idoc--SOAP Sync Process Scenario Using BPM .
I have configured every thing using BPM and mapped
MATMAS----SOAP Request
SOAP Resp----STATUS.SYSTAT01
In R/3 the Main Idoc Number(MATMAS) Status needs to be update , but it is creating the new Idoc with STATUS.SYSTAT01.
I have used STATUS.SYSTAT01 Idoc to Update the status of the Original idoc based on the Response that is coming from webservice .
I was posted the same thread a days ago and there Bhavesh suggested me some sugessions.
How can we make the status of the Idoc based on some response Text
iam unable to follow OR not able to clear my self on this.
Please suggest me or give some over view kind of thing on this
RegardsHi Suman,
It is clearly mentioned in SAP help that "SAP Intermediate Documents (IDOCS) are EDI like documents that are asynchronous in nature."
So Your Scenario is Asynch(receive) - Synch(WS call) -Transformation (Multimapping)- Asynch(Send to R/3).
now go in this way:
you can develop all the message Interfaces of Abstract catagory (not manditory )
MI_AA_MATMAS -> Abstract Asynchronous message interface for your Matmas IDOC
MI_AS_SOAP_ReqandResp -> Abstarct Syncronous MI for SOAP request and response.
MI_AA_STATUS ->Abstract Asyncronous MI for Status Idoc
MI_AA_SOAP_Req -> Abstarct Asyncronous MI for SOAP request .
MI_AA_SOAP_Res -> Abstarct Asyncronous MI for SOAP response .
Thats all in Message interface.
your first reciever :
(This will receive the message asynchronously from R/3)
create a conatainer varaiable (say preceive) and assign it message interface MI_AA_MATMAS
Now in thw Propert TAB of this step: give this message name.
Step2: Synchronous call :
create container Variable psoaprequest and psoapresponse give abstract message interface MI_AA_SOAP_Req and MI_AA_SOAP_Req resp.
Now in thw Propert TAB of this step:
Synchronous Interface : MI_AS_SOAP_ReqandResp
Request Message : psoaprequest
Response Message: psoapresponse
Transformation Step :
Here you will specify Interface Mapping that will conatain Multimapping between Synch Response - MATMAs and STATUS
Let's name it as IM_ResandMatmasToStatus
create a container variable as pstatus and assign it abstract interface MI_AA_STATUS.
In Property pan of this step :
Interface mapping :IM_ResandMatmasToStatus
Source Message :psoapresponse
preceive
(IT will ask you for two source messages as IM selected in this transformation has 2 source messages)
Target Message :pstatus
Send step:
Select a message as pstatus.
thats all in IR.
If have doubt in ID just let me know.
Thanks

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.

}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.

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) -
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.
