Call to java bean but code not being executed.

Making a call to my javabean class called ch06_03.java from a jsp program shown below:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Using a java package.</title>
</head>
<body>
<% beans.ch06_03 messager = new beans.ch06_03(); %>
The message is: <%= messager.msg() %>
</body>
</html>
The call from jsp to javabean program is only returning the hello from java and NOT EXECUTING ANY OF THE CODE in the msg() method. I am checking my table landings_hold and nothing is there, my log file shows nothing. Why is the code not being executed except for the return statement?
My javabean program is shown below:

Since you didn't use code-formatting tags ([ code ] and [ /code ] without the spaces) it's kinda hard to look at it. But I'm sure it DID execute much more than just the return statement - maybe you're not closing a file or db connection, or maybe you're seeing a cached page, so it actually isn't executing ANYTHING on the server (is your browser set to never check for newer pages so it (almost) always returns from cache, for example?)

Jsp code not being executed in browser

Even though my applications deploy and redeploy, I can see .html files but not .jsp files. The server presents the path, i.e. http://localhost:7001/ITDC/index.jsp, but the jsp code is either not being compiled and exceuted in a client browser or the .jsp is being compiled but not executed in the client broswer.

          How about you tell us exactly what happens, and what you expected to happen. I
          can't tell if you're getting error messages, or whether you just don't see what
          you expect on the screen.
          Note that JSP code is not ever executed in the browser. It's only ever executed
          in the appserver, and the generated output is viewed in the browser.

Code not being executed????

Am using a session varible to test an if statement, if true then statement is executed, else nothing. The session variable appears to be false but the statement is still being executed, any suggestions. Possibly a browser specific problem?
The code in question is as follows....
if((session.getAttribute("accessrights")!=null)&&(session.getAttribute("accessrights").equals("3"))) { %>
<html statement >
<html statement>
<% } %>
The value of accessrights prior to the If statement is '1' and it is still being executed. Any suggestions very gratefully recieved!!!!!

Correction: the code should be as follows. It always displays the class and value of that attribute. So you can see if that is what you expect. If it is, then the problem is fixed. Could you also show what you see on your browser when using the following code?
<html>
<p> attribute class is <% = session.getAttribute("accessrights").getClass().getName() %> value is <% = session.getAttribute("accessrights").toString() %> </p>
if (session.getAttribute("accessrights")!=null) {accessRights = (String)session.getAttribute("accessrights"); }
<% if(accessRights.equals("3")) {%>
<% } %>
</html>

When I tried to log into my itunes account, I was asked to update my credit card information. When I confirmed my credit card info, I got a response about my security code not being accurate -which is not the case-it is 100% accurate. How do I fix?

I keep getting a message about my security code not being accurate. I tried 3 different cards & have the same issue. Is this a systems issue? I need to get my apps installed on my new iPhone 4. I am unable to download without confirming my credit card info- My security codes are 100% accurate.Anyone else having this issue? What is the fix for this?

Ohemod,
There are 120+ countries that have iTunes Stores, but that leaves many that do not. You can consult this document: iTunes Store: Which types of items can I buy in my country?
Opening in a new country requires a tremendous amount of legal, commercial and financial investment, but I am sure Apple would be interested in knowing where there is unmet demand. If you wish to make suggestions to Apple, you can use the iTunes Feedback page.

Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

Do you have a smaller capacity micro SD card to try? I seem to remember from past posts that users were having problems with cards larger than 32GB, however, Apple's page doesn't mention this.

My iphone 5 for some reason can receive calls, send & receive texts but can not call out

My iphone 5 for some reason can receive calls, send & receive texts but can not call out

I am not sure if this issue is going to help you but lets give it a try.
I know that where im from, which is the Netherlands, I am not able to sent e-mails from my iPhone or any other mobile device by using 3G or a random WIFI acces point. The provider only allowes you to sent e-mails when you are connected to a network of there own. Which means if you have provider "101" and your email settings are set up for this provider in your iPhone but your using the network of a friend of yours which is provider "202" you cannot sent emails from his network. Though you can receive them you may not sent.
As I said, I am not aware if this issue is the same for you totaly depents on the country and provider your using.

If you have any suggestion, please let me know!

Thanks anyhow;
The following information is sent to beginners site.
I have talked to british, belgian and others regarding this problem. They said it is very expensive and we laughed.
Hi,
Windows XP runs java application but does not compile it. I get following message:

Would you please tell me what is wrong?

Dinamic Configuration not being executed

Hi All,
   I'm working on a new interface, file2file. The new file name is not known because it depends on the mapping process so I have configured the FileName options in the Sender and Receiver channels and I can see the new
<SAP:Record namespace="http://sap.com/xi/XI/System/File" name="FileName">XXXXXXXXX</SAP:Record>
   and it uses it to write the file.
   In the mapping process, a new User-Defines function is called, it is the very same as all the posts about this option.
   The messate type is something like this:
               label1
                    RECORD
                          LINE_ITEM
                                 DATA
    If I place the new function during the DATA mapping, it works but, if I move it to the label1 it seems that it is not being called. Is there any reason for this? Due to the number of boxes for the filename calculation I moved to label1.
    Help would be appreciated for this.
    Thanks and kind regards,
       Encinas.

Hi,
it means that you're label mapping is not being executed
try adding a trance in your user defined function
and you'll be able to see it this will be executed during the mapping
(in the test tab)
how to add trace:
/people/michal.krawczyk2/blog/2005/02/25/simple-java-code-in-graphical-mapping--xi
basically you can put it anywhere in your mapping as long as the user defined function will be executed

Transform not being executed

Hi,
I have a mapping as shown here:
http://sourcebase.sourceforge.net/iviewcapture_date_12_05_2004_time_18_55_52.png
It is a fairly simple one: there is a main table BC_DEPT from where I'm populating the ODS_DEPT table, and there is a delta table D_BC_DEPT from where I need to get the maximum watermark value and call a package procedure called SET_WATERMARK with this as the parameter.
The problem is that the procedure SET_WATERMARK is not being executed. I have checked in the debugger and the execution stops after output from the Aggregate operator. Plus, I searched for SET_WATERMARK in the generated mapping code and there is no reference to it in the code ! Executing the Main() procedure of the mapping also does not run this transform.
The only significant thing about the transform procedure is that it is a synonym which points to the actual package in another instance over a DB link.
Any help / pointers would be appreciated.
Thanks in advance,
Biswa.

Yes, basically I want to call a procedure with the output of the AGG operator on a table. I ftransformations must have a output, how do I achieve this ? I have currently worked around it by creating an output table to store the output and then calling a wrapper procedure from the post mapping which reads the parameters from the table. But this seems a rather messy way to achieve something rather simple and obvious: read data from a table; do some stuff; call a procedure with the output !
Can it be done in a simpler manner in this release ?
Regards,
Biswa.

XSLT for adding Namespace is not being executed at runtime

Hi Gurus,
I am trying to add a Namespace to inbound xml and I wrote a simple XSLT mapping as below, when I execute this using XML spy or in Operation mapping manually it is working fine and giving me output as expected but at runtime it is not executing, I am getting same input xml as output xml and receiver agreement is failing...
Appreciate your thoughts..
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:output method="xml" encoding="UTF-8"/>
        <xsl:template match="*">
          <ns0:SalesXmlExtended xmlns:ns0="urn:/company.com/H/sndr">
          <xsl:copy-of select="//SalesReportInfo"/>
     </ns0:SalesXmlExtended>
     </xsl:template>
</xsl:stylesheet>
input xml is as below....
<?xml version="1.0" encoding="UTF-8"?>
<SalesXmlExtended>
     <SalesReportInfo>
          <SalesReport>
               <Detail>
                    <deptNum>0270</deptNum> etc...
output I am getting in XMLSpy and OM is as below, this is exactly what I need...
<?xml version="1.0" encoding="UTF-8"?>
<ns0:SalesXmlExtended xmlns:ns0="urn:/company.com/H/sndr">
     <SalesReportInfo>
          <SalesReport>
               <Detail>
                    <deptNum>0270</deptNum>
Thanks...

Hi Baskar,
Yeah, that is what my issue is , it shouldn't be failing but it is...
I tried by manipulating the required namespace in the input file and it is working fine with out any errors....so I am guessing the XSLT is not being executed...
I am getting below error which is valid because the transformation is not happening
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">

Validation function, PL/SQL is not being executed

Hello there,
In one of my APEX listener setups I want to give access to only one application and block the rest. Basically I am following this nice post from Kris Rice: http://krisrice.blogspot.com.ar/2013/01/apex-listener-plsql-validations.html
My problem is that my validation function is not being executed:
- In ${config.dir}/apex/conf/apex.xml
<entry key="security.requestValidationFunction">MY_SCHEMA.MY_PACKAGES.is_allowed(flow_id=>:P_FLOW_ID,page_id=>:P_FLOW_STEP_ID)</entry>- The function code:
FUNCTION is_allowed(
    flow_id IN VARCHAR2,
    page_id IN VARCHAR2)
RETURN BOOLEAN
AS
BEGIN
insert into MY_SCHEMA.logs values (sysdate, flow_id);
IF ( flow_id = 141 ) THEN
    RETURN true;
END IF;
RETURN false;
END;But the logs table remains empty, snif...
Any ideas?
Thanks in advance,
Luis

SubQuerry Not being executed

Hi Gentelmen;
I have posted this question in the Test and Playground Forum but no one has responded.
Any of you experts in this forum may be able to help me please...
I have this problem where I am selecting records to display on the report from table customer and trying to count how many booking are there for each customer in booking table based on the customer id from booking table.
here is my query code below...
select id name city custtype discount into (wa-scid, wa-scname, wa-sccity, wa-scctype, wa-scdisc) from customer
where city = 'CityName' and
country = 'CountryName' and exists (
select count( distinct custid ) as wa-cnt from bookings group by custid ).
WRITE: /1 wa-scid, 11 wa-scname, 40 wa-sccity, 70 wa-scctype, 78 wa-scdisc,'%', 90 wa-cnt.
endselect.
I have tried to debug the issue and seems like the sub query is not being executed. The reason i say that because the value of wa-cnt which is a counter of type i is not changing.
Any one can shed some light in this matter/problem please...
Many Thanks.

You are using AS addition in the subquery to determine whether the subquery is being executed or not, and I think this is wrong. AS addition has only meaning when your using wither INTO or APPENDING, it wouldn't change the value of wa-cnt.
I suggest you to try to change the subquery to
and exists ( select count( * ) from bookings ).
As you're using only the COUNT aggregation expression int the subquery, a GROUPING is not necessary.
