Required Java Code for Validation

Hello Everybody
I need a java Code To validate the value exist in system
For an user Defined Function.
                        System A value Need to Compare in System B.
                          IF the value exist in System B Then need to sent to System C.
                  early answer would be great

HI,
Lookup has to be use in this case.
Steps to be done:
1) Get the value from the file and pass that value to R3 system using JAVA lookup.
2) In R3 end under the function module write a code which checked the PO with the PO which is present in R3.
3) Return the value of the comparision to UDF and then pouplate the value in IDOC.
I hope this is what u want.
Lookup links are below:
Some use cases:
     Look up material number from table MARA.
     Look up cost center budget.
     Look up employee information.
     Look up unit-of-measure (UOM) information from table t006a.
     Lookup for raising an alert.
There are two ways in which we can do lookup:
     Call lookup method from GUI mapping.
     Call lookup method from XSLT mapping.
Lookup method from GUI mapping can be called using any of the following ways.
     RFC lookup using JCO (without communication channel)
      /people/sravya.talanki2/blog/2005/12/21/use-this-crazy-piece-for-any-rfc-mapping-lookups
     RFC lookup with communication channel.
                 /people/alessandro.guarneri/blog/2006/03/27/sap-xi-lookup-api-the-killer
     Lookup using JDBC adapter.

      /people/sap.user72/blog/2005/12/06/optimizing-lookups-in-xi
     CSV file lookup.
      /people/sundararamaprasad.subbaraman/blog/2005/12/09/making-csv-file-lookup-possible-in-sap-xi
Call lookup method from GUI mapping: Use this for ur scenario:
The steps are as follows:
     Develop and test ABAP function module.
     Develop and test Java method within Integration Repository/message mapping tool.
Check this weblogs with some screenshots on how to achieve this:

Safari Update required security code for validation

I have an I Phone 5 & 6. Received a request for a Safari update. First asked for phone number. None entered were accepted. Then asked to enter security code sent to you in order to complete validation. Did not receive a security code. Don't know what this is asking for. Any suggestions?

I had this problem this morning on my iPhone 5. I went into Settings>>Safari>>Clear History and Website Data and clicked that. Unfortunately you'll lose any pages you had open as well as browsing history. However, this solved the problem immediately.

Provide the java code for the following scenario.

Hi Experts,
I have tried with all the combinations for this scenario. As per my understanding i require java code for the following scenario
so that it becomes easy........
I require a Message mapping for this Logic.
In the Source there are 4 fields and, the Target side, the fields should appear like this.
Source Structure- File
Record
|-> Header
Order_No
Date
|-> Item
Mat_No
Quantity
Target Structure-IDoc
IDoc
|-> Header
|-> Segment
Delivery_Order_No
Recv_Date
|-> Item
|-> Segment
Delivery_Order_No
Material_Num
Recv_Quantity.
The Logic is for every Order number an IDOC is generated.And if the Material num matches then the quantity should be added. and important note is that the material numbers are different for every order number. That means if a material number is 2 in the order number A. Then the material number can never be 2 in any of the order numbers.Here is the following with an example for the above scenario.
For example:-
we have
Source Structure- File
Order-no Date Mat_No Quantity
1 01/02/2011 A 10
1 01/02/2011 B 15
1 01/02/2011 A 10
2 01/02/2011 C 10
2 01/02/2011 C 10
3 01/02/2011 D 20
3 01/02/2011 D 10
3 01/02/2011 E 25
Target Structure-IDoc
Delivery_Order_No Recv_Date Material_Num Recv_Quantity
1 01/02/2011 A 20
1 01/02/2011 B 15
2 01/02/2011 C 20
3 01/02/2011 D 30
3 01/02/2011 E 25
So for this example total of 5-Idocs created. That means for this example if Order_No is 1 When the Mat_No is A the quantity gets added. For this Scenario 1 IDoc with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) is generated by adding the quantity field in the Target Side. Similarly if Order_No is 1 when the Mat_No is B then separate IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) in the Target Side. Similarly, if Order_No is 2 when the Mat_No is C, an IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) by adding the quantity field in the Target Side. ike wise the process goes on upto 3.Kindly do the needy..
Kindly provide the java code.
Thanq very much in advance..

what i have understood from ur example is that u want to generate an idoc for unique combination of Order-no and Mat_No
if yes then chk the below mapping..
change the context of Order_No, Date, Mat_No and Quantity to Record (right click-> context)
1)
Order-no
----------------------concat[;]---sort----splitbyvalue(valuechanged)-----collapse context---IDoc
Mat_No
2)
Order-no
--------concat[;]---sort----splitbyvalue(value changed)---collapse context---UDF1--splitbyvalue(each value)--Delivery_Order_No
Mat_No
3)
Order-no
-----------concat[;]---sortbykey----------------------- \
Mat_No                       /                            \
Date--------------- /                                       \
----------------------------------------------------------FormatByExample-----collapsecontext---splitbyvalue(each value)----Recv_Date
Order-no                                                 /
-----------concat[;]---sort----splitbyvalue(value changed)
Mat_No
4)
Order-no
--------concat[;]---sort----splitbyvalue(value changed)---collapse context-UDF2--splitbyvalue(each value)--Material_Num
Mat_No
5)
Order-no
-----------concat[;]---sortbykey
Mat_No                       /
Quantity --------------- /
----------------------------------------------------------FormatByExample-----SUM(under statistic)----Recv_Quantity

Creating Java code for the function module

Hi Colleagues,
I have a fuction module in ABAP system. Now I want to Generate java code for the FM.
I cam to know that we can achive that using AXIS, By getting the XML file for the fuction module and generate Java
Class file using that XML file.
Can any one tell me how to achive it.
Or any other way to do that?
Please provide you valid suggestions.
Regards,
Sathya

Hi,
You can integrate axis2 in eclipse. I think you have to find the plugin for that.
After that you can let axis generate the jave code (stubs and proxies) for your web service via the wsdl file.
Kind Regards,
Robin

I Need Java code for following Algorithm

* I Need Java code for following algorithm. Kindly any one help.
1. Read the contents (ideas and its corresponding scores) from two files named as 'a' and 'b'.
2. Stored the file 'a' contents in array a[].
3. Stored the file 'b' contents in array b[].
4. compare both files like
if(a.equals(b[j])
Writing the common idea and add the score from file 'a' and 'b'.
else
write the uncommon idea and its score..
For example :
Form Agents.txt
action,65
architecture,85
eco-,15
essay,30
form,85
form,85
link,40
tangent,25
Form Agents1.txt
Black holes,69
essay,78
Herewith i have above mentioned two files named as Form Agents and Form Agents1.
Form Agents has eight fields
Form Agents1 has two fields
--> 'essay' is common in two files, so store the idea 'essay' and add the score from Form Agents score is '30' and Form Agents1 has 78 (essay 108).
Finally it stores idea in another file with uncommon fields also.
Please help us.

We have tried with following code.
But we cant add the scores.
For Example:
Form Agents.txt --> has "essay,30"
Form Agents1.txt --> has "essay,78"
Result is: essay,108
Finally it stores idea in another file with uncommon fields also.
So Any one pls correct the following code.
try

Do we require Java stack for ADS?

Hello Experts
i am planning to work on Adobe forms on ECC6. Since it is our ECC system we don't have ABAP stack to that.
i went through some ADS documentation which says to add java hostnames and port numbers to the ADS Comm channel. also it seems from the architecture that ADS runs into the java stack.
hence do we require java stack for running ADS or we can install a patch of the same.
Thanks in advance.
Regards
Rajeev

Hello,
the ADS is a JAVA Webservice >> You need the Java stack.
Please use the search function!
Best regards,
Dezso

Weblogic 6.0 (SP2) generates incorrect java code for JSP with response.sendRedirect()

          Hi,
          Here are the steps to reproduce the problem with the examplesWebApp application
          bundled with wlserver6.0(sp2):
          Product: Weblogic server 6.0 (sp2)
          Browser: IE 5.0
          1. Add index.jsp as the welcome file in WEB-INF/web.xml
          2. Create index.jsp as below:
          <%
          response.sendRedirect("index.html");
          return;
          %>
          <html>
          <head>
          <title>Index JSP file</title>
          </head>
          <body>
          <font color="red">This is index.jsp file </font>
          </body>
          </html>
          3. Create index.html as below:
          <html>
          <head>
          <title>Index HTML file</title>
          </head>
          <body>
          <font color="red">This is index.html file </font>
          </body>
          </html>
          4. Run the examples server and make sure examplesWebApp is deployed on the examples
          server using the console
          5. Access the URL http://localhost:7001/examplesWebApp
          The page will display a compilation error as below:
          C:\bea\wlserver6.0\config\examples\applications\examplesWebApp\WEB-INF\_tmp_war_examplesServer_examplesServer_examplesWebApp\jsp_servlet\_index.java:89:
          unreachable statement
          out.print("\r\n<html>\r\n<head>\r\n<title>Simple html</title>\r\n</head>\r\n<body>\r\n<font
          color=\"red\">This is index.jsp page</font>\r\n</body>\r\n</html>\r\n");
          ^
          and a look at the generated java code for index.jsp (_index.java) will reveal
          the erroneous code snippet below in the jsp service method:
          try { // error page try block
          //[ /index.jsp; Line: 1]
          response.sendRedirect("index.html"); //[ /index.jsp; Line: 2]
          return; //[ /index.jsp; Line: 3]
          out.print("\r\n<html>\r\n<head>\r\n<title>Simple html</title>\r\n</head>\r\n<body>\r\n<font
          color=\"red\">This is index.jsp page</font>\r\n</body>\r\n</html>\r\n");
          } catch (Exception __ee) {
          while (out != null && out != _originalOut) out = pageContext.popBody();
          pageContext.handlePageException(__ee);
          The above web application works fine in Tomcat 3.2.X environment. The Weblogic
          server 6.0 servlet engine should not generate the "out.println()" corresponding
          to the html section of index.jsp. The moment it sees the "return", it should stop
          processing further.
          Can someone from Weblogic support team please verify this and let me know when
          this bug will be fixed?
          One interesting thing I noticed was when we last tried weblogic 6.0 at its beta
          stage, it worked fine after we put in a special patch jar file called "redirectfix.jar"
          we received from weblogic team but somehow it got re-introduced by the time it
          was released!!
          We are planning to migrate our product from tomcat 3.2.x to weblogic 6.0. Our
          product has a lot of pages with such conditional {response.sendRdirect("page.jsp");return;}
          blocks. We would really appreciate a faster response form weblogic team.
          Thanks in advance.

Why should it stop when it sees a return? Is that in the spec?

And no one here is just simply going to give you code anyway. We'll help you correct yours, and give you advice and tips, but we are not going to do your work for you. And urgent it is not, not to us. And your insisting that it is, is rude. We definately are not going to drop everything we might be doing to "help" you, especially when your essentially demanding that we do your work for you, with no effort on your part, besides.

How to convert these java codes (for a feedback) to javabean?

Can anyone please help me to convert these java codes (for feedback) to javabean using the MVC Model-View-Controller pattern design?

int newTrashCanMsg = 0;
String currentUserID = 1+"";
String adminID = 1+""; //change this ID to your adminID in the db
try
//Load the JDBC driver
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
//Get the connection getConnection("access driver", "userID", "password")
con = DriverManager.getConnection("jdbc:odbc:FREN_DB","","");
stmt = con.createStatement();

Okay, first suggestion is to never create database connections in JSP/Servlet. SInce you mentioned MVC, JSP is the View, and a servlet can be the controller to process requests and redirect accordingly.
This piece of code should be in a class invoked from the model layer (business logic components) preferably with some abstraction. Maybe you should search around for DAO pattern. That might give you an idea.
