My servlet is running in weblogic server.
But when I am running this program in weblogic server side there is no log.

I would run both sides in a debugger and see what code is getting invoked

Problem while invoking popup from backing bean

I am invoking a popup from backing bean method.
The same backing bean method has the business logic which depends on the data collected from popup(user enters some data on popup).
So I need the business logic to be executed after popup comes up.
The popup is coming after the execution of return statement in backing bean method . How do i make popup trigger at earlier point in the method.
<af:commandToolbarButton text="#{corePostupgradeuiBundle.SIGN_OFF_MIG}"
id="socb52"
partialSubmit="true"
actionListener="#{viewScope.signoffBean.signOffAgents}"
partialTriggers="t3"/>
public void signOffAgents(ActionEvent event) throws SQLException {
DCBindingContainer bc =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding summaryIter =
bc.findIteratorBinding("Signoff1Iterator");
showPopup("credentials"); //will get credential details from user and store in credential Bean
//Following logic uses the data collected from popup
EMCredentialReference credRef= credentialBean.getCredReference();
submitJOb(credRef);
public static void showPopup(String popupId) {
FacesContext context = FacesContext.getCurrentInstance();
StringBuilder script = new StringBuilder();
script.append("AdfPage.PAGE.findComponent(\"").append(popupId).append("\").show();");
ExtendedRenderKitService erks =
Service.getService(context.getRenderKit(),
ExtendedRenderKitService.class);
erks.addScript(context, script.toString());
UIComponent component = context.getViewRoot().findComponent(popupId);
RequestContext.getCurrentInstance().addPartialTarget(component);
}

Well, your work flow is wrong.
What you try to accomplish should work out of the box as
1) user hit toolbar button
2) this opens a popup "credentials" which have listeners for ok and cancel
3) use fills in data in popup and hit ok or cancel
4) one of the listeners gets fired
5a) if OK listener you do your business logic
5b) if cancel you do something else
So all you have to do is the use a af:af:showPopupBehavioron the toolbar button, add a popup canel listener (if you need to act on canel) dependign on your popup design (dialog or simple button) add the appropriate listeners and in the listener method so your business logic.

UIX Problem: How call a nonstatic java bean?

Now with a better subject! It's the same Problem like my post:
How can I call a nonstatic class
Hello All,
I've wrote a simple bean for my testcase that count a value (e.g. site access):
public class Bean1 {
private int accessCount = 1;
public int getAccessCount() {
return (accessCount++);
If I call the bean with a jsp-site, it works fine with different scope. e.g. session and application.
With session scope different browser count different. With application scope different bowser count together. Thats the normal attitude.
My jsp code:
<jsp:useBean id="counter" class="ml.view.Bean1" scope="session" />
<jsp:getProperty name="counter" property="accessCount" />
This don't work with a static bean (normal too), but I can only call a static class in my UIX site.
I call the bean from uix with the invoke element. Is that correct? How can I call a nonstatic class with a special scope? Which other solution ist possible?
My uix code:
<invoke method="getAccessCount" result="${uix.eventResult.getAccessCount}" instance="${sessionScope.Bean1.getAccessCount}" exception="${uix.eventResult.error}" javaType="ml.view.Bean1"/>
Thank you for any solution!
The error messages are:
java.lang.NullPointerException
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
at java.lang.reflect.Method.invoke(Method.java)
at oracle.cabo.servlet.event.InvokeEventHandler._invoke(Unknown Source)
at
and so forth...

Hello,
try right clicking on the bean and select Create Data Control.
The bean will then appear on your data control pallet and you can drag the field onto your UIX page.
you may be able to acheive this using EL in your example, but i am not sure how to do this. I know the above solution works. You can also use the binding container in any struts action to get hold of your bean and perform any actions on it.

Brenden

C:import tag - Query string while calling servlet from JSP

Hi,
From my JSP I am calling a servlet to write back to the response stream of the JSP. From the JSP i am trying to pass some values into the query string as follows
     <%
     String strGetParameters = "/servlet/MyServlet?path=" + strPath;
      %>
     <pre><c:import url="<%=strGetParameters%>" /></pre>In the servlet I try to get the path from the query string by using
request.getParameter("path")But in the servlet the query string doesnt have the "path" parameter that I added in the strGetParameters string (in the JSP).
Am i missing something? Do i have to use something else or do something else?
Any help is appreciated.

I've taken some time to do a simple test and it just works.
Here is the test code, it was tested in Java EE 5 + JSTL 1.2 + Tomcat 6.

Calling Servlet from Java-Class

Hi,
I have a normal java-class that is working with request/response Objects. From within this class I want to call a local servlet, let it do some work with the request and the response and then return it to the class.
I guess the RequestDispatcher can only be called from within a Servlet, but my class is not a servlet.
The getServlet()-method is not working any more.
Maybe somebody has an idea.
Thanks a lot,
Matthias

MatthiasThis is not very pretty, so I think you should redessign, but you can open a URLConnection from your class pointing to the URL of the servlet. As far as I know you can't invoke a servlet directly, because you can't get a reference to it, it can only be invoked by the container...

Problem while calling RFC in java

hi,
I writed a java program calling a batch input RFC. The RFC return an internal table which storing the system messages of the batch input process. My problem is:
When i debug the java program,the RFC excecuted and return the correct internal table to me.
But when i executed it not in debug mode, there is no batch input messages return to me.

hi,
i had resolved my problem in other way.I don't upload my data using ws_upload now,but upload with table.
here is my code.Maybe helpful to somebody:
       JCO.Table C_XYORDERTable;
     JCO.Table C_XYORDPR_FINALTable;
     public void getXyordprFinalElement(Element e) {
          try {

                    Element child = (Element) i.next();
                    if (child.getName().equals("ORDER_ID"))
                         C_XYORDPR_FINALTable.setValue(child.getText(), "ORDER_ID");
                    else if (child.getName().equals("ID"))

Authentication failure message while calling UMWebService from Java

Hi All:
I am trying to consume UMWebService published in EP. The URL for this webservice is:
"http://<server>:<port>/irj/servlet/prt/soap/UMWebService?Wsdl".
I ceated a web reference to this WebService in my WebDynproJAVA project. But when I called one of the methods(getMapping()) on this webservice, a SOAP Exception has occured with the following message: "The User Authentification is not correct to access to the Portal Service UMWebService or the service was not found."
How would I solve this problem to provide the Authentication for the webservice.
Thanks in advance,
Munna_SAP

Hi Munna,
if your WAS requires user authentication you should do this:
1. set-up security options of Logical Port in you WS Model (Security tab > set HTTP Authentication)
2. before WS executing set user name and password:
wdContext.currentRequest_UMWebService_getMappingElement().modelObject()._setUser("user");
wdContext.currentRequest_UMWebService_getMappingElement().modelObject()._setPassword("pwd");
Let me know if this help,
regards

Bad Request while calling servlet from MIDlet

Hi All,
I am trying to call a servlet(running on Tomcat) thru my MIDP application using HttpConnection. But I am getting "Bad Request" error 400. The code is as given below:
package myTests;
import java.io.*;
import javax.microedition.io.*;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public class Hello extends MIDlet implements CommandListener {
private Display display;
private Form props;
private StringBuffer propbuf;
private Command exitCommand = new Command("Exit", Command.EXIT, 1);
* Construct a new HelloObject.
public Hello() {
     display = Display.getDisplay(this);
public void startApp() {
     propbuf = new StringBuffer(50);
     props = new Form("System Properties");
HttpConnection c = null;
InputStream is = null;
StringBuffer b = new StringBuffer();
try {
c = (HttpConnection)Connector.open("http://127.0.0.1:8080/gsf/servlet/HelloServlet", Connector.READ);
c.setRequestMethod(HttpConnection.GET);
c.setRequestProperty("User-Agent", "Profile/MIDP-1.0 Configuration/CLDC-1.0");
c.setRequestProperty("Content-Language", "en-US");
is = c.openInputStream();
props.append(c.getResponseMessage());
props.append(c.getURL());
props.append(c.getRequestMethod());
props.append((new Long(c.getLength())).toString());
catch( Exception e)
props.append(e.getMessage());
     props.addCommand(exitCommand);
     props.setCommandListener(this);
     display.setCurrent(props);
public void commandAction(Command c, Displayable s) {
     if (c == exitCommand) {
     destroyApp(false);
     notifyDestroyed();
public void pauseApp() {
     display.setCurrent(null);
     propbuf = null;
     props = null;
* Destroy must cleanup everything.
public void destroyApp(boolean unconditional) {
ANY HELP ON THIS WOULD BE APPRECIATED.
Thanks,
Neel

Hi GaRRy,
Thanks for responding.
1) Yes, I want to use the GET method. If I type the url that I've put to Connector.open() in the browser, it gives the following output:
Servlet invoked!
Mon Sep 24 12:45:44 EDT 2001
But when I run the emulator it gives the following output
OK
http://127.0.0.1:8080/gsf/servlet/HelloServlet
GET -1
2) I don't know why, but the error log does not show any error for this request on the http server. (I am using Tomcat.). Also I am sure that the doGet method of the servlet gets called as it prints the debug message.
Thanks,
Neel

Problem with calling Webservice from Java Webdynpro

Hi,
I have a scenario where I need to call a Webservice through my Webdynpro application. I need to pass few parameters(of type string) and the Webservice is suppose to retrun a few records based on the input values.
When I run the webservice directly using the browser, the output is in XML format.
When I create a model for the webservice in webdynpro, the return value is a Node element of type java.lang.Object. From webdynpro, I am successfully able to make a call to the Webservice (as there is no exception with model execute command), but the return value is always null. I am not sure if the webservice is not returning any data or if I am not reading the correct context element. There is no documentation available for the webservice either.
Can anyone tell me what is that I am missing. Is it not possible for Webdynpro to call a webservice which can return only XML data?
Any help on this issue would be greatly appreciated.
Thanks,
Sudheer

Hi Sudheer,
You can refer to wiki link (& other links available at the end in this)

Problem while calling webservice from a plsql stored procedure

Hi everybody,
I need to call a webservice from a plsql stored procedure.
I was following documentation published in the otn at the following link.
"http://www.oracle.com/technology/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html"
I am encountering the following error on my sql prompt-
SQL> exec dbms_output.put_line(time_service.get_local_time('94065'));
BEGIN dbms_output.put_line(time_service.get_local_time('94065')); END;
ERROR at line 1:
ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1022
ORA-12545: Connect failed because target host or object does not exist
ORA-06512: at "APPS.DEMO_SOAP", line 65
ORA-06512: at "APPS.TIME_SERVICE", line 13
ORA-06512: at line 1
Has anybody worked on the same example. Please direct me.
Thanks & Regards

Kiran, were you able to solve this?
I am facing the same error.
Oracle Server is Unix and webservice is .NET.
I am able to connect to Java web service.

Problem while calling concsub from shell script

Hi All,
I am facing problem when I am trying to run CONCSUB utility from shell script.The same works well when I try it from command line.The only prob I am facing from shell script is assigning values to temporary variables.
This is how my script looks
#!/bin/bash
export PARM5="$5"
export PARM6="$6"
export PARM7="$7"
echo "INTPARM5=\"$PARM5\""
echo "INTPARM6=\"$PARM6\""
echo "INTPARM7=\"$PARM7\""
echo $FND_TOP/bin/CONCSUB $1 ONT 'Order Management Super User, Vision Operations (USA)' $3 WAIT=Y CONCURRENT ONT $PROGRAM "$INTPARM5" "$INTPARM6" "$INTPARM7"When I try to run the above shell based concurrent program it doesn't pass the parameters as expected and it errors out saying "Wrong number of arguments to call the procedure"
I tried my luck from some of the previous posts ({thread:id=2360776} ),but to vain
If anyone has any ideas,please suggest!!
