Reading from CEP http channel

How we can read from a CEP subscribed http channel through a servlet?

yes my application will be hosted by IBM in certain environment...and the URL i am going to call through AJAX is in another domain..
thing is...sometime i'll get the page but not the js and css for the external domain URL....
where as i received an input from my archietect that if i make HTTP Socket connection with that URL and specify the allotted port number as well...then we are making the call from a valid connection channel...and that will make the content come back to me....with js and css...
not sure still how it will differ from direct URL call.
is that what you are lookign for?

Web Service; Error attempting to read from file

I'm trying to connect to a web service as outlined by the book "Creating Dynamic Forms with Adobe LiveCycle Designer" which is an excellent book by the way.
I'm receiving the following error "Error attempting to read from file. http://www.webservicex.net/BibleWebservice.asmx"
I've successfully created the Data Connection to
http://www.webservicex.net/BibleWebservice.asmx?wsdl
I dragged and dropped the bookTitle, chapter & Versie onto the form. I also dragged and dropped the GetBibleWordsByChapterAndVerseResult and the GetBibleWordsByChapterAndVerseBtn.
I Preview PDF and click the button I get the above error.
Does anyone have experience using Web Services with Adobe LiveCycle ES and have advice on how to resolve this. Any Suggestions would be greatly appreciated.
-Todd

Well, I have more news on the error I'm getting. - NO I didn't find the problem. Yet
I checked and made sure that web.config had "None" selected " in authentication mode. I.E. <authentication mode="None" /> This should eliminate any authentication problems since that turns off IIS's authentication checking.
At first I was thinking the form was generating the error trying to read the result coming back from the web service, but I put in some code that writes the result to a log file when the method fires off.
I noticed that when I clicked on the button on the form, the error message would pop up from Acrobat, but when I check the log file, there was NO entry. This means that Acrobat failed before it could execute the method.
Here is the web method:
[WebMethod(CacheDuration = 30,
Description="Returns the String 'True' or 'False' whether or
not you entered a 'T' or 't'.")]
public string TF(string Tf)
string result="False";
if(Tf.Substring(0,1).ToLower()=="t"){
result= "True";}
LogFile.Write("Sent: "+result);
return result;

Why do I get IOException on nio read from channel before all data is read?

I am working on an NIO based http client library but I've noticed two problems.
#1: I have been testing against an http server that has authentication turned on. Hence, any request that comes its way will respond with a '401 Authentication Required' response. In the case of a POST, I've noticed that this particular http server does not wait for the body to arrive before responding. As soon as it gets the headers, it dumps the 401 response onto the channel and closes the connection. My library then gets an IOException on the next write to the channel even though I've received write interest event. (I'm using non blocking mode)
Whether I get the exception depends on timing. Sometimes, my writes work and the exception is averted. Sometimes not. The longer I delay since the time I get the write interest event, the more likely it is the exception will occur.
Now, in this situation, I really think it's the http server that is violating the http protocol. I give a valid content length that is not zero but it does not wait for me to finish my request. The moment I write the last empty line of the header section, it responds and closes the channel. Even though I don't think this is correct, my library has to deal with it. So in this situation, I've decided my library will abandon the write phase and move on to reading the response.
NOTE: In the majority of cases, a client would have already authenticated by landing on some page that could produce a POST in the first place. However, for technical reasons I can't mention here, I must support the case that the very first (unathenticated) request to the server is a POST.
2) After #1 above occurs, reading from the channel will also throw an IOException but only on Windows. Sometimes I get the headers only, sometimes the whole document, sometimes nothing. Again, the longer I delay reading (since the time I get the read interest event) the more likely it is the exception will be thrown. This NEVER happens on Linux. I always get the full response on Linux after the #1 happens even if I put long delays between reads.
I can understand #1 happening but #2 should not. I can always see the complete response data on the wire using a network protocol analyser. The data is there every time but my library doesn't always get it.
In situation 2, there is nothing I can do. If I don't receive the data, I have to respond with an error even though the request was successful.
I have stripped down my library to the bare essentials and can reproduce the problem in a self-contained environment every time.
Any ideas why the discrepency between Windows/Linux? Does this seem right?

I read through the section you mentioned. I realize the connection may be dropped at any time. Handling this is no problem. It is reported as an exception to the client. However, this situation is different. I still see no provision that allows a server to respond to a half written request. A request is defined to include an optional message body (Section 5). The client dictates whether it is optional, not the server. Furthermore, section 6 clearly states "After receiving and interpreting a request message, a server responds with an HTTP response message.". To me, this implies the server must wait for the entire request before responding even if its a waste of time. This particular server is attempting to short circuit what I see is the required request/response cycle. In doing so, it is causing me some pain in trying to deliver its response since it seems on windows this interferes with my ability to read it.
The simple answer to this is to process reads before writes, i.e. OP_READ before OP_WRITE. I tried this as well. Originally, I was not even registering READ interest while I was writing my request. (I saw no reason to. I don't want to give my client a response while they are writing their request.) But even when I do register READ interest while I'm writing (and process read events before write), the read event still produces no data and no eof (-1) indication on the read. The discrepency between linux and windows is bothering me. No matter what I do, I can't deliver the response even though its written to the channel by my peer. I think I will supply some code and see if anyone can get it to work on windows.Edited by: r2rossi on Sep 24, 2008 10:42 AMEdited by: r2rossi on Sep 24, 2008 10:43 AM

What should be configured as channel in Oracle CEP HTTP adapter for remote publishing?

Hi,
Below is the adapter configuration that I have for Oracle CEP HTTP adapter for remote publishing. What exactly should be configured in <channel> here? In the oracle documentation example, it only says /channel2 as an example.
Below is the HTTP adapter configuration file that I have created.
<?xml version="1.0" encoding="UTF-8"?>
<wlevs:config xmlns:wlevs="http://www.bea.com/ns/wlevs/config/application">
    <http-pub-sub-adapter>

        <channel>/RESTfulWS</channel>
        <event-type>com.wipro.event.ResultEvent1</event-type>
    </http-pub-sub-adapter>
</wlevs:config>
'/RESTfulWS' in my above configuration is the context-root of my rest service.But this is not working so I would like someone to help me understand this configuration.
Many thanks.

Sowmya

Hi, Sowmya,
From your configuration
Is the http://localhost:8080/RESTfulWS/rest/UserInfoService/post/jsonstream httppubsub server? I don't think the oep http pub adapter can publish event to rest service.
For http pub adapter, you can take a look at fx sample, it publishes events to a embedded http pub/sub server of oep.
Thanks,

About the read from http request, I think it is a bug in weblogic

Hi guys,
sorry for the previous post, I press the wrong button, I didn't finished yet.
I have experienced a problem when I try to read from http request in a web application.
the following is my code:
InputStreamReader isr = new InputStreamReader(new URL("www.myhost.com").openStream(),"8859_1");
BufferedReader bfr = new BufferedReader(isr);
String request = "";
while((request = bfr.readLine()) != null)
stringGotFromServer += request;
the problem is it always hang in there when BufferdReader reach the end.
but in java specification, BufferedReader should reture null if reaching the
end.
Does anyone have any good idea for that?
Thanks in advance.

Hi,
I think if you follow the instructions as given in the example you will not have any problems.
here are the instructions below
"This example code demonstrates one technique of handling test failures.
If this step fails, a dialog will be displayed giving options to Break, Terminate, or Retry.
The On Fail Post Action calls the HandleTestFailure sequence which is
another sequence in this sequence file.
The sequence file has the SequenceFilePreStep Callback overridden where
the initial statue of Runstate.SequenceFailed is stored in a local variable. Create a local variable in your sequence called SequenceAlreadyFailed which is a boolen.
To use this in your sequence file:
1. Copy the HandleTestFailure sequence to your sequence file.
2. For a step to use this, you
must set the On Fail Post Action to call the
HandleTestFailure sequence.
3. Override the PreStepCallback.
4. Copy the step from this example's PreStepCallback to yours.
5. Copy the TestFailureDialog.* files to the same directory as your sequence file.

Hi,
The Java Secure Socket Extension (JSSE) library from Sun Microsystems lets you access a secure Web server from behind a firewall via
proxy tunneling. To do this, the JSSE application needs to set the https.ProxyHost and https.ProxyPort system properties. The
tunneling code in JSSE checks for "HTTP 1.0" in the proxy's response. If your proxy, like many, returns "HTTP 1.1", you will get an
IOException. In this case, you need to implement your own HTTPS tunneling protocol.
In this article, I will show you how to create a secure socket that tunnels through the firewall, and pass it to the HTTPS stream handler to
open HTTPS URLs using the URLConnection class.
Open the http tunnel socket to the proxy
The first step to creating your secure socket is to open the tunneling socket to the proxy port. The code needed to do this proxy
handshaking can be found in the sample code SSLClientSocketWithTunneling.java that comes with the JSSE distribution. First, a normal socket is created that connects to
the proxy port on the proxy host (line 65). After the socket is created, it is passed to the doTunnelHandshake() method where the proxy's tunneling protocol is called:
54 SSLSocketFactory factory =
55 (SSLSocketFactory)SSLSocketFactory.getDefault();
56
57 /*
58 * Set up a socket to do tunneling through the proxy.
59 * Start it off as a regular socket, then layer SSL
60 * over the top of it.
61 */
62 tunnelHost = System.getProperty("https.proxyHost");
63 tunnelPort = Integer.getInteger("https.proxyPort").intValue();
64
65 Socket tunnel = new Socket(tunnelHost, tunnelPort);
66 doTunnelHandshake(tunnel, host, port);
In doTunnelHandshake(), an http "CONNECT" command is sent to the proxy, with the secure site's hostname and port number as the parameters (line 161). In the original
tunneling code on line 206 in JSSE, it then checks for "HTTP/1.0 200" in the proxy's reply. If your organization's proxy replies with "HTTP 1.1", an IOException will be
thrown. To get around this, the code here checks for the reply "200 Connection Established", which indicates that tunneling is successful (line 207). You can modify the
code to check for the expected corresponding response from your proxy:
139 private void doTunnelHandshake(Socket tunnel, String host, int port)
140 throws IOException
141 {
142 OutputStream out = tunnel.getOutputStream();
143 String msg = "CONNECT " + host + ":" + port + " HTTP/1.0\n"
144 + "User-Agent: "
145 + sun.net.www.protocol.http.HttpURLConnection.userAgent
146 + "\r\n\r\n";
147 byte b[];
148 try {
149 /*
150 * We really do want ASCII7 -- the http protocol doesn't change
151 * with locale.
152 */
153 b = msg.getBytes("ASCII7");
154 } catch (UnsupportedEncodingException ignored) {
155 /*
156 * If ASCII7 isn't there, something serious is wrong, but
157 * Paranoia Is Good (tm)
158 */
159 b = msg.getBytes();
160 }
161 out.write(b);
162 out.flush();
163
164 /*
165 * We need to store the reply so we can create a detailed
166 * error message to the user.
167 */
168 byte reply[] = new byte[200];
169 int replyLen = 0;
170 int newlinesSeen = 0;
171 boolean headerDone = false; /* Done on first newline */
172
173 InputStream in = tunnel.getInputStream();
174 boolean error = false;
175
176 while (newlinesSeen < 2) {
177 int i = in.read();
178 if (i < 0) {
179 throw new IOException("Unexpected EOF from proxy");
180 }
181 if (i == '\n') {
182 headerDone = true;
183 ++newlinesSeen;
184 } else if (i != '\r') {
185 newlinesSeen = 0;
186 if (!headerDone && replyLen < reply.length) {
187 reply[replyLen++] = (byte) i;
188 }
189 }
190 }
191
192 /*
193 * Converting the byte array to a string is slightly wasteful
194 * in the case where the connection was successful, but it's
195 * insignificant compared to the network overhead.
196 */
197 String replyStr;
198 try {
199 replyStr = new String(reply, 0, replyLen, "ASCII7");
200 } catch (UnsupportedEncodingException ignored) {
201 replyStr = new String(reply, 0, replyLen);
202 }
203
204 /* We check for Connection Established because our proxy returns
205 * HTTP/1.1 instead of 1.0 */
206 //if (!replyStr.startsWith("HTTP/1.0 200")) {
207 if(replyStr.toLowerCase().indexOf(
208 "200 connection established") == -1){
209 throw new IOException("Unable to tunnel through "
210 + tunnelHost + ":" + tunnelPort
211 + ". Proxy returns \"" + replyStr + "\"");
212 }
213
214 /* tunneling Handshake was successful! */
215 }
Overlay http tunnel socket with SSL socket
After you have successfully created the tunneling socket, you overlay it with the SSL socket. Again, this is not difficult to do:
54 SSLSocketFactory factory =
55 (SSLSocketFactory)SSLSocketFactory.getDefault();
56
57 /*
58 * Set up a socket to do tunneling through the proxy.
59 * Start it off as a regular socket, then layer SSL
60 * over the top of it.
61 */
62 tunnelHost = System.getProperty("https.proxyHost");
63 tunnelPort = Integer.getInteger("https.proxyPort").intValue();
64
65 Socket tunnel = new Socket(tunnelHost, tunnelPort);
66 doTunnelHandshake(tunnel, host, port);
67
68 /*
69 * Ok, let's overlay the tunnel socket with SSL.
70 */
71 SSLSocket socket =
72 (SSLSocket)factory.createSocket(tunnel, host, port, true);
73
74 /*
75 * register a callback for handshaking completion event
76 */
77 socket.addHandshakeCompletedListener(
78 new HandshakeCompletedListener() {
79 public void handshakeCompleted(
80 HandshakeCompletedEvent event) {
81 System.out.println("Handshake finished!");
82 System.out.println(
83 "\t CipherSuite:" + event.getCipherSuite());
84 System.out.println(
85 "\t SessionId " + event.getSession());
86 System.out.println(
87 "\t PeerHost " + event.getSession().getPeerHost());
88 }
89 }
90 );
The code had called the SSLSocketFactory's getDefault() method earlier to get an instance of the SSLSocketFactory (line 54, repeated above). Next, it passes the
tunneling socket that was created in the previous step to the createSocket() method of the SSLSocketFactory. The createSocket() method returns an SSLSocket that is
connected to the destination host and port via the proxy tunnel. You can optionally add a HandshakeCompletedListener to the socket if you wish to be informed when the
SSL handshaking is completed.
The SSLSocket created is basically ready for use to transfer secure contents. The startHandshake() method is called to start the SSL handshaking (line 98). After which, you
can issue the http "GET" command to retrieve the secure pages (line 105):
91
92 /*
93 * send http request
94 *
95 * See SSLSocketClient.java for more information about why
96 * there is a forced handshake here when using PrintWriters.
97 */
98 socket.startHandshake();
99
100 PrintWriter out = new PrintWriter(
101 new BufferedWriter(
102 new OutputStreamWriter(
103 socket.getOutputStream())));
104
105 out.println("GET http://www.verisign.com/index.html HTTP/1.0");
106 out.println();
107 out.flush();
However, issuing http commands to the tunneling SSL socket to access Webpages is not ideal because it would mean having to rewrite the whole http protocol handler from
scratch. Instead, you should use the HTTPS URL APIs that the JSSE already includes for that purpose. To do this, you have to pass the tunneling SSL socket to the HTTPS URL
stream handler.
Pass SSL socket to HTTPS URL stream handler
The JSSE library has an HttpsURLConnection class that is in the com.sun.net.ssl package, which extends the java.net.URLConnection class. An HttpsURLConnection object
is returned by the URL object's openConnection() method when "HTTPS" is specified as the protocol. The HttpsURLConnection class has a method, setSSLSocketFactory(),
that lets you set an SSLSocketFactory of your choice. To pass the tunneling SSL socket to the HTTPS URL stream handler, you would set the setSSLSocketFactory()
method's parameter with a socket factory that returns the tunneling SSL socket that you created previously.
To do this, you would wrap the code discussed previously in an SSLTunnelSocketFactory class that extends from the SSLSocketFactory class. The SSLSocketFactory is an
abstract class. To extend it, you must implement the createSocket() method to return the tunneling SSL socket that you created earlier:
12 public SSLTunnelSocketFactory(String proxyhost, String proxyport){
13 tunnelHost = proxyhost;
14 tunnelPort = Integer.parseInt(proxyport);
15 dfactory = (SSLSocketFactory)SSLSocketFactory.getDefault();
16 }
44 public Socket createSocket(Socket s, String host, int port,
45 boolean autoClose)
46 throws IOException,UnknownHostException
47 {
48
49 Socket tunnel = new Socket(tunnelHost,tunnelPort);
50
51 doTunnelHandshake(tunnel,host,port);
52
53 SSLSocket result = (SSLSocket)dfactory.createSocket(
54 tunnel,host,port,autoClose);
55
56 result.addHandshakeCompletedListener(
57 new HandshakeCompletedListener() {
58 public void handshakeCompleted(HandshakeCompletedEvent event) {
59 System.out.println("Handshake finished!");
60 System.out.println(
61 "\t CipherSuite:" + event.getCipherSuite());
62 System.out.println(
63 "\t SessionId " + event.getSession());
64 System.out.println(
65 "\t PeerHost " + event.getSession().getPeerHost());
66 }
67 }
68 );
69
70 result.startHandshake();
71
72 return result;
73 }
Notice that the SSLTunnelSocketFactory contains a default SSLSocketFactory object. The default SSLSocketFactory object can be instantiated from a call to the static
method getDefault() (line 15). You need this SSLSocketFactory object to overlay the tunnel socket with the SSL socket, as discussed earlier. You also call the default
object's getDefaultCipherSuites() and getSupportedCipherSuites() methods when implementing the corresponding abstract methods of the SSLSocketFactory super
class. For implementation details, please refer to the complete source code for the SSLTunnelSocketFactory in Resources.
Tunnel through the proxy via URLConnection
To tunnel through the proxy via URLConnection in your JSSE application, after you call the openConnection() method, check if the returned object is that of the
HttpsURLConnection. If so, you instantiate your SSLTunnelSocketFactory object and set it in the setSSLSocketFactory() method (lines 22 through 25):
10 public class URLTunnelReader {
11 private final static String proxyHost = "proxy.sg.ibm.com";
12 private final static String proxyPort = "80";
13
14 public static void main(String[] args) throws Exception {
15 System.setProperty("java.protocol.handler.pkgs",
16 "com.sun.net.ssl.internal.www.protocol");
17 //System.setProperty("https.proxyHost",proxyHost);
18 //System.setProperty("https.proxyPort",proxyPort);
19
20 URL verisign = new URL("https://www.verisign.com");
21 URLConnection urlc = verisign.openConnection(); //from secure site
22 if(urlc instanceof com.sun.net.ssl.HttpsURLConnection){
23 ((com.sun.net.ssl.HttpsURLConnection)urlc).setSSLSocketFactory
24 (new SSLTunnelSocketFactory(proxyHost,proxyPort));
25 }
26
27 BufferedReader in = new BufferedReader(
28 new InputStreamReader(
29 urlc.getInputStream()));
30
31 String inputLine;
32
33 while ((inputLine = in.readLine()) != null)
34 System.out.println(inputLine);
35
36 in.close();
37 }
38 }
You can then access the HTTPS URLs using the APIs provided by the URLConnection class. You don't need to worry about the format of the http GET and POST commands,
which you would if you used the SSL Socket APIs.
The complete source code for the SSLTunnelSocketFactory and the application code that connects to a secure URL using proxy tunneling is included in Resources. To
compile and run the application, you would need to download and install Sun's JSSE from its Website, also listed in Resources.
Conclusion
If your JSSE application could not tunnel through your organization's firewall, you need to implement your own tunneling socket. The sample code included with the JSSE
distribution shows you how to open an SSL socket tunnel. This article goes one step further to show you how to pass the tunneling socket to the HTTPS URL stream handler,
and saves you the trouble of rewriting a http handler
I hope this will help you.

How can I select events from two different channels?

Hi everybody, I have another question! :)
When processing events in config.xml, using a CQL sentence, Eclipse compiler doesn't allow me to select more than one event.
I paste here my app.context.xml and my config.xml:
app.context.xml:
<wlevs:event-type-repository>
<wlevs:event-type type-name="HorseEvent">
<wlevs:class>com.bea.wlevs.event.example.sevenhorses.HorseEvent</wlevs:class>
</wlevs:event-type>
<wlevs:event-type type-name="GunmanEvent">
<wlevs:class>com.bea.wlevs.event.example.sevenhorses.GunmanEvent</wlevs:class>
</wlevs:event-type>
</wlevs:event-type-repository>

<wlevs:adapter id="sevenhorsesAdapter" class="com.bea.wlevs.adapter.example.sevenhorses.SevenHorsesAdapter" >
<wlevs:instance-property name="messageHorse" value="I am the horse number: "/>
<wlevs:instance-property name="messageGunman" value="I am the gunman number: "/>
</wlevs:adapter>
<wlevs:channel id="horseInputChannel" event-type="HorseEvent" >
<wlevs:listener ref="sevenhorsesProcessor"/>
<wlevs:source ref="sevenhorsesAdapter"/>
</wlevs:channel>
<wlevs:channel id="gunmanInputChannel" event-type="GunmanEvent" >
<wlevs:listener ref="sevenhorsesProcessor"/>
<wlevs:source ref="sevenhorsesAdapter"/>
</wlevs:channel>

<wlevs:processor id="sevenhorsesProcessor" />
<wlevs:channel id="horseOutputChannel" event-type="HorseEvent" advertise="true">
<wlevs:listener>
<bean class="com.bea.wlevs.example.sevenhorses.SevenHorsesBean"/>
</wlevs:listener>
<wlevs:source ref="sevenhorsesProcessor"/>
</wlevs:channel>
<wlevs:channel id="gunmanOutputChannel" event-type="GunmanEvent" advertise="true">
<wlevs:listener>
<bean class="com.bea.wlevs.example.sevenhorses.SevenHorsesBean"/>
</wlevs:listener>
<wlevs:source ref="sevenhorsesProcessor"/>
</wlevs:channel>
And here you are the two config.xml, I have tried two different ones and none of them runs.
The first one is:
<?xml version="1.0" encoding="UTF-8"?>
<n1:config xmlns:n1="http://www.bea.com/ns/wlevs/config/application">
<processor>
<name>sevenhorsesProcessor</name>
<rules>
<query id="horsesRule">
<![CDATA[ select * from horseInputChannel
        ]]>
</query>
<query id="gunmansRule">
<![CDATA[ select * from gunmanInputChannel
        ]]>
</query>
</rules>
</processor>
</n1:config>
As you can see, I use here TWO CQL sentences from the two channels that are defined in app.context.xml.
The other one is:
<?xml version="1.0" encoding="UTF-8"?>
<n1:config xmlns:n1="http://www.bea.com/ns/wlevs/config/application">
<processor>
<name>sevenhorsesProcessor</name>
<rules>
<query id="horsesRule">
<![CDATA[ select * from horseInputChannel, gunmanInputChannel
        ]]>
</query>
</rules>
</processor>
</n1:config>
I use here only ONE CQL sentence in which I try to get events from the two channels that are defined.
None of them works.
Can anybody help me?
Thank you!

Read from serial-usb converter?

I have an oxygen detector with serial out
link to the owners manual with serial info
http://www.yokogawa.com/an/download/manual/IM11M10B01-01E.pdf
and I want to hook it up to my laptop to record the data but i am having trouble as my laptop has no serial port. so i bought this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16812120901&nm_mc=OTC-Channel&cm_mmc=OTC-channel...
How do i read from the usb converter? I can program serial in with the visa on an old pc no problem, but this is giving me some trouble. Any advice would be appreciated thankyou.

I just ran the driver setup wizard in visa and got this error for the keyspan dongle.
That might be bad news. My company actually assigned an engineer to buy every USB to COM converter he could find and test them all with as many apps as possible. There were many models that were problematic. You might need to just try another brand (or two (dozen!)).
Still, check the Device Manger or MAX just in case you get lucky...

Message failing in SXMB_moni----Error while reading from the secure store

Hi,
The scenario is as below
A file is picked up from a folder and processed to enrich it.This enriched file is then written back in a different folder.
The message is failing in sxmb_moni while trying to write the file in the folder.
The PI system is a system copy of another system and few of the configuration objects are transported through a tpz file to this PI system.The file receiver channel used to write this file is also transported through this tpz file.
Below is the error seen in moni.:

Is this because PI system is a system copy of another system ?

Error while reading access data (URL, user, password) for the Adapter Engine
Check out Michal's reply:
Re: URL for Central Adapter Engine
As you said there was a system copy it may be the case that some things were not configured properly

Error SOAP: call failed: java.io.IOException: Read timed out; HTTP 200 OK

Hi PI gurus,
Need some suggestions on one issue below -
Scenario - proxy (SAP) to SOAP (Web based system)
In the RWB Communication Channel Monitirong we are receiving the below error
" Error SOAP: call failed: java.io.IOException: Read timed out; HTTP 200 OK"
the request from XI system is going to target system and printing the lables (as per the functionality) with no issues but the comminication channel is giving the above error and this is causing the repeated sending the same request to target sytem and the data is printing repeateadly. This issues is occuring in Quality environment.
Strangley the same Interface with the same connectivity details is working fine in Development environment. But not working in Quality environment. Checked the firewalls settings on both in XI and Target system side and confirmed that everything is fine.
Below are the Logs both from Quality and developement are as follows
Quality ( Failure Case)
17.03.2011 07:19:59 Success SOAP: request message entering the adapter with user J2EE_GUEST
17.03.2011 07:25:03 Error SOAP: call failed: java.io.IOException: Read timed out; HTTP 200 OK
Development (Success ful)
17.03.2011 07:27:55 Success SOAP: request message entering the adapter with user J2EE_GUEST
17.03.2011 07:27:58 Success SOAP: completed the processing
When we checked with basis team on user id J2EE_GUEST, they confirmed that they are same in Development and Quality.
I repeat,, that the same target url and everthing is same in XI Configuration
Thanks in Advance. Points would be rewared for the best solution.
Thanks,
Jitender

HI Jitender,
If your scenariois working in DEV and if it is not working in QAS.Could you please check if both the systems are at same patch levels..
Please refer below notes :1551161,817894,952402.

Has anyone ever successfully done a cont double buffer acq from multiple SCXI channels AND a spare AI of the MIO that controls the SCXI chassis at the same time?

I am trying do a sanity check before I order some hardware.
What I want to do is acquire from multiple channels in a SCXI chasis and as part of the same acquisition, also read from one of the "un-used" AI channels of the MIO card.
My concern is this:
All of the channels of the SCXI chassis get multiplexed down into a single channel of the MIO card that controls the SCXI chassis. This means that channel 0 has to do multiple A/D conversions to get a reading from all of the configured SCXI channels.
Meanwhile, the other AI channel of the MIO only has to do one to get it's reading. It seems that the on-boar
d clock of the MIO would have to run at two rates to be able to read all of my SCXI channels AND the other AI channel.
What I want to do:
I want to just configure a vitual channel for all of my SCXI channels AND one more for one "odd-ball" signal that is incompatable with all of the SCXI modules.
Then I just want to list all of my virtual channels when I configure and start my continuous double buffered acquisition.
I have successfully done all SCXI channels before, but I have never tried to use one of the un-used AI on the MIO at the same time. I have used the spare DIO lines previously, but that will not work in this app.
So...
If you have done this and it worked, I would greatly appreciate hearing about any special techniques that were used, etc.
Thank you for reading this question,
Ben
