Communication Protocols while Calling a BPEL from another BPEL

Hi,
I was just curious to understand that what is the protocol that gets used when a BPEL WS is called from another BPEL using Partner Link ?
Is it SOAP over HTTP or some internal network call in the BPEL engine.
If someone can point to a detailed documentation for it, that would be helpful.
Thanks,
Saurabh

Hi Veejai24 and soa_adf,
Thanks for your replies. My question here was more to analyze if an internal call of BPEL to another BPEL takes the same amount of time as if a BPEL is called from any external application over HTTP. Or the BPEL Engine reduces this time while internal calls and optimizes the performance?
Thanks,
Saurabh

OC4J_10.1.3 (Exception while calling a webservice from another webservice)

I have the following situation --
1. I have two WebServices A and B deployed onto OC4J_10.1.3
They both work when I test them using the test service
2. My real need is to call webservice A from B. So I created a proxy for A using JDEV
and deployed into OC4J. Now when I use the test service and call methods on B as before it does not work. I get the following exceptions when I try to instantiate the stub.
WebServiceASoapHttpPortClient myPort = new WebServiceASoapHttpPortClient();
SEVERE: caught exception while handling request: java.lang.NoSuchMethodError: oracle.j2ee.ws.common.encoding.literal.LiteralFragmentSerializer.<init>(Ljavax/xml
/namespace/QName;ZZLjavax/xml/namespace/QName;Ljava/lang/String;Z)V java.lang.NoSuchMethodError: oracle.j2ee.ws.common.encoding.literal.LiteralFragmentSerializer.<init>(Ljavax/xml/namespace/QName;ZZLjavax/xml/namespace/QName;Ljava/lang/Stri
ng;Z)V
It seems as though OC4J is not able to find LiteralFragmentSerializer methods. But wsclient.jar must be available on OC4J's CLASSPATH.
My webservice is very simple and the encoding is SOAP1.1 (Document/Literal).
Any insights ?
Thanks very much.

Have you tried downloading and installing wsclient_extended.jar instead of wsclient.jar?

Error Invoking BPEL from another BPEL

Hi,
I was trying to invoke a BPEL process deployed on the server from another via the partner link activity. In the WSDL URL I gave the server URL for the WSDL, but upon attempting to parse it, the composite gave an error http 502. However, when I try to invoke services that aren't in the SOA contanier, they work out fine. Could anybody say what I'm doing wrong?

Hi,
Spoke with the network team, and it is indeed a proxi server problem, I just had to apply for some previlagess, and turn off the proxy checking on Jdev, and I'm home free. Thanks anyway, all.
Bye for now.

Error while calling a form from another form's menu item

I created a main form and menu module for this form.
I am calling another form from main form menu item.
i moved both the forms and menu and compiled them.
But, when i run this form i am getting an error saying
FRM 92100: Your connection to the server was interrupted
This may be the result of a network error, or a failure on the server.
You will need to establish your session.
I set the seperateframe = true
networkentries = 30
But still getting the same error.
Is there any parameter that i am missing.
I will greatly appreciate if anybody can direct me to the solution.
Thank you.
Navya.

Error while calling oracle reports from another report

Hello everyone,
I have a problem running oracle reports. In one report I have a button
that calls another report. There is a button for each row of the result
in the first report , and i have used Srw.run_report to call the second
report.
My problem is, when I run the report, at the first time i can push the
button and the second report opens and works correctly. But if i close
the second report and come back to the first one, when i push the
button for a different row ,the second report starts to run but then I
get some oracle errors like table does not exist or... while the first
time the report worked correctly.
It seems that when i close the second report and go back to the first
one, sth happens that changes my session or connection. I don't know
what can be the problem.
By the way, when I log in with the user that owns the tables and has
all the privileges, I don't get this problem. It only occurs when I
use other users ( which have all privileges on all of the tables
needed in the report )
I am using Report Builder 6.0.5 and the DB is Oracle Database 10g.
Can anyone please help me with this problem?
Thanx in Advance.
Maryam.

6.0.5 is not certified against 10g database, so I suggest to upgrade to 6.0.8.26 (6i patch 17) first to see if the problem is gone.

Urgent:Error While calling one form from another form

Hi,
i am using a form in which zoom functionality is enabled.From this form if i am clicking view->zoom it should open another form which should accept two parameters from the first form.But whenever i am clicking on zoom its giving the following error.
FRM-47023:No such parameter named G_QUERY_FIND exists in form
XX_EMPLOYEE_CONVERSION(Name of the form which i am calling from first form)
When i am clicking 'ok' then it shows the error
FRM-40105:Unable to resolve reference to item PARAMETER.G_QUERY_FIND
Eventhough i have developed my form using template.fmb which uses the parameter G_QUERY_FIND why this error is coming?
Can anyone suggest a solution for this.
Thanks in advance

PARAMETER.G_QUERY_FIND is one of he objects in the APPSTAND.fmb. You will need to Subclass all of the objects in APPSTAND.fmb in your custom form. If you do not have a copy of this file in your FORMS60_PATH, I suggest you put a copy there. If you don't have a FORMS60_PATH specified then I would highly suggest adding this entry to your Forms Home in the Registry. Also, you will want all of the libraries in the AU_TOP/Resources folder as well.
I also suggest looking at the Oracle Applications Developer's Guide (http://download.oracle.com/docs/cd/B25284_01/current/acrobat/115devg.pdf) as it outlines all of the required objects you must have in your form and reports.
Hope this helps.

Compilation error while calling static method from another class

Hi,
I am new to Java Programming. I have written two class files Dummy1 and Dummy2.java in the same package Test.

package Test;
import java.io.*;
public class Dummy1
public static final int var1= 10;
public static int varDisp(int var2)
return(var1+var2);
This is program is compiling fine.
I have called the static method varDisp from the class Dummy2 and it is as follows
package Test;
import java.io.*;
public class Dummy2
public int var3=15;
public int test=0;
test+=Dummy1.varDisp(var3);
and when i compile Dummy2.java, there is a compilation error <identifier > expected.
Please help me in this program.

public class Dummy2
public int var3=15;
public int test=0;
test+=Dummy1.varDisp(var3);
}test+=Dummy1.varDisplay(var3);
must be in a method, it cannot just be out somewhere in the class!

How to call a servlet from another servlet

hi everybody,
i have a problem, i have to call one servlet from another one.
Everything works on my pc, but when i install the application on the customer's server i got an error about an Uknown URL followed by the name of the machine.
Wjat i do is the folloqing :
String urlString = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+"/"+servletName;
URL url = new URL(urlString);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
the variable servletName is the name of the servlet i have to call.
Is there another way to call the servlet ?
All the servlet are installed in the same server.
Any suggestion ?
Cheers.
Stefano

Sweep is correct about requestDispatcher being another approach for inter-servlet delegation; the only issue that i recall with this approach is that it defaults the method of the destination servlet to the one it was called from...for example, calling servlet2 from within servlet1.post() resulted in the dispatcher attempting to utilize servlet2.post() - i believe that i searched for a parameterize solution to no avail :( (ended up handling the request by placing a "fake" doPost() in servlet2 that simply called servlet2.doGet())
however, if your application is functioning correctly on your pc/webserver then the problem may be external to servlet communication (e.g. client webserver's ports not configured or blocked, missing runtime classes, etc.)
my suggestion would be to set aside the programmatic concerns for the moment - what is the response if you open a browser on a client's machine and access the URL in question (i.e. http://clientserver:port/stefanoServlet)? If it will not respond to access in this manner then it certainly won't when your application calls for it.
It's possible that there is a coding error but, given the info supplied, i'd start examining the environment, first. Let us know if you have any luck with the test i recommended or not (please provide abundant detail). Or, if you've found the solution then you may want to post back with a quick blub so the next person knows how to escape the trap.

Calling a method from another file

This is pretty basic stuff but i can't seem to get it right. I am calling a method from another file. The other file IS located in the same folder BUT when i compile i get errors
"cannot find symbol" <===referring to limit and sieve i believe.
The method name is "sieve" the file name is "PrimeSieve2008" and "limit" is the variable in brackets in the real method.
     public static void main (String [] args) {
final int [] PRIMES;
int sieve = PrimeSieve2008.sieve(limit);
     PRIMES = sieve(getValidInt());
          for (int j = 0; j<PRIMES.length; j++) {
               System.out.println("Prime[" + j + "] = " + PRIMES[j]);
Is "int sieve = PrimeSieve2008.sieve(limit)" the wrong way to call a file?
Thanks a million,
Alex

I really am clueless here.in this one you are passing in limit.
in the other one you are getting limit from somewhere outside of main.

Invoking bpel process from another bpel process in same app server

Hi,
When I invoke a bpel process from another bpel process in the same oracle AS
1. Is it a SOAP call or is there any optimization?
2. If there is some optimization where can I configure this?
3. Is there any similar optimizations if I invoke a bpel process from a
java application deployed in the same server? If so can you please provide
a sample?

By default the BPEL 10.1.2, it will do a local call to the process. It will not execute a SOAP request, no network access is done.
It can be configured at domain level:
Parameter: optSoapShortcut (SOAP local optimization)
Turns on "short-cut" for local SOAP request; local SOAP calls are normally done via an internal call instead of sending a message through the SOAP stack.
The default behavior for the engine is to optimize all. To disable optimization specify a value other than "true" or "yes".
