How to read a user defined java method inside a javascript
I have a scenario where I have a form with 2 fields and a submit button. On clicking submit button, I call a javascript which needs to call a user-defined method.
Please provide solution to do this and also please provide any useful links that i can go follow.
Thanks
Java != javascript.
You can not call java directly from javascript.
The lifecycle:
Request received
Java/JSP runs produces an HTML page
Java stops running
Javascript runs on page when page is loaded.
The only way to call java code again is to submit a request and get the result back in a response. Traditionally the response is a new JSP page to replace the old one.
Using AJAX the response can be just information that you then alter the current page with.
The first example given by skp71 will probably NOT be what you are after. The java code is executed when you load the page, NOT when you push the button which is most probably what you are after.
AJAX is a solution, as is loading a new page.

How to read static variable defined java class from flex?
This is a beginner question. If I use remoteClass to map a java class and a flex class, how can I access a static variable defined in java class from the flex code?
Thanks!Static propeties are by default ignored in the blazeds for serialization. You can try using another global property in the java bean which maps to the value stored in the static property( Hopefully it should work)
eg,
public String instanceValue = ClassName.staticValue;

How to use a user defined function in XI
Hi Experts,
I would like learn how to use a user defined function in Xi during mapping . Is there any step by step on that.
Besides during when me make communcaton channels I see the following tabs...Paramters ..Identifiers ...Module...
The module that is given here ...where and how it is used.Hi,
You can write UDFs in java in Graphical mapping to enhance your XI Graphical mapping functionality
The steps for doing it would be:
1. Click on Create New function Button found on Bottom left corner on your XI Mapping window.
2. Write your java code.
3. Run the Mapping Test as usual.
>>The module that is given here ...where and how it is used.
The adapters in the Adapter Framework convert XI messages to the protocols of connected external systems and the other way around. When doing so, some
functionality might need to be added specific to a situation which is possible with the use of custom modules.
Typical example would be validation of file content when using a File Adapter or modification of the message payload to a common content structure which is not supported by any of the standard SAP modules.
An Adapter module is developed as an Enterprise Java Bean and is called locally by the Adapter.
An example on modules :

How to catch the user defined exception in application service
Hi All,
How to catch the user defined exception in application service when it is throwed by the external service..
Regards,
Thirumurugan.Hi,
Thanks for your reply,
Actually I am calling validate Login method of External service from the application service. When the login fails, my external service will throw user defined Exception.I want to catch the user defined Exception.
But in the application service , validate Login method can catch only Invocation Exception and Engine Exception.
These two exception are present in the Application service remote interface.
public com.sap.comptest.extsrv.accrjavawsvi__document.output.
Ns1_validateLoginResponse validateLogin(com.sap.comptest.extsrv.accrjavawsvi__document.input.Ns1_validateLogin input) throws com.sap.caf.mp.base.exception.InvocationException, com.sap.caf.mp.base.exception.EngineException;
User defined exception is not present there. When i include the webservice as external service in CAF, it suppossed to generate the java file for the custom exception of validate Login method and this generated file should be included in the application service remote interface..
public com.sap.comptest.extsrv.accrjavawsvi__document.output.
Ns1_validateLoginResponse validateLogin(com.sap.comptest.extsrv.accrjavawsvi__document.input.Ns1_validateLogin input) throws com.sap.caf.mp.base.exception.InvocationException, com.sap.caf.mp.base.exception.EngineException,
(generated file name of user defined Excpetion.
Then only validate login method of application service can catch the user defined Exception which is thrown by the external service.

How to let the user define the colors for each plots in the graph (I use LabVIEW 7)?
How to let the user define the colors for each plots in the graph (I
use LabVIEW 7)?Hi,
Take a look at this example, it uses property nodes to select tha
active plot and then changes the color of that plot.
If you want to make the number of plots dynamic you could use a for
loop and an array of color boxes.
I hope this helps.

How can I use User-Defined Aggregate Functions in Timesten 11? such as ODCI
Hi
we are using Timesten 11 version and as per the documentation, it doesn't support User-Defined Aggregate Functions.
So we are looking for alternatives to do it. Could you please provide your expert voice on this.
Thanks a lot.
As the following:
create or replace type strcat_type as object (
cat_string varchar2(32767),
static function ODCIAggregateInitialize(cs_ctx In Out strcat_type) return number,
member function ODCIAggregateIterate(self In Out strcat_type,value in varchar2) return number,
member function ODCIAggregateMerge(self In Out strcat_type,ctx2 In Out strcat_type) return number,
member function ODCIAggregateTerminate(self In Out strcat_type,returnValue Out varchar2,flags in number) return
number
How can I use User-Defined Aggregate Functions in Timesten 11? such as ODCIAggregateInitialize ?Dear user6258915,
You absolutely right, TimesTen doesnt support object types (http://docs.oracle.com/cd/E13085_01/doc/timesten.1121/e13076/plsqldiffs.htm) and User-Defined Aggregate Functions.
Is it crucial for your application? Could you rewrite this functionality by using standart SQL or PL/SQL?
Best regards,

How to add a user defined HTTP header field?
Hi, everyone!
I want to add a user defined HTTP header field to a HTTP
response header.
I use the following statements in testHeader.jsp
response.addHeader("myheader", "123");
response.sendRedirect("middleHeader.jsp");
in middleHeader.jsp,
out.print(request.getHeader("myheader"));
But the output in middleHeader.jsp is null!
How to add a user defined HTTP header field to a HTTP
response header? Are there some sample codes?
Cheers,
Georgethe send redirect actually creates a new request (through the client) and thus a new response
thus the headers you set in the response are gone for the next request/response

How to send a user defined parameter to a web form?
Hi,
I4m looking for a solution how to send a user defined parameter to a web form when I start the form from a html-page.
I think that it should work to add the parameter to the URL.
Example: I added myparam=myvalue at the end oft the URL
http://my.server.com:7777/f60cgi?form=myform.fmx&userid=scott/tiger@mydb&otherparams=useSDI=NO&lookAndFeel=generic&colorScheme=teal&myparam=myvalue
How can I fetch the parameter myparam in forms?You have the user the otherParams parameter, which you can specify in the formsweb.cfg file, or override on the url. e.g. http://myhost/servlet/f690servlet?config=myApp&otherParams=myParam=myValue
In the Forms Builder, in the Navigator window, there is a node called Parameters. Create one in there, and then you can refer to it like a block variable. e.g. if :myparam = 'myvalue' then...
At runtime, Forms will match up any parameters on the command with parameters defined in your form, and populate them for you. You don't have to do anything.

Robin Zimmermann

How to read system eventlog using java program in windows?
How to read system eventlog using java program in windows?
is there any java class available to do this ? or any one having sample code for this?
Your friend ZoeHi,
There is no java class for reading event log in windows, so we can do one thing we can use windows system 32 VBS script to read the system log .
The output of this command can be read using java program....
we can use java exec for executing this system32 vbs script.
use the below program and pass the command "eventquery"
plz refer cscript,wscript
import java.io.*;
public class CmdExec {
public static void main(String argv[]) {
try {
String line;
Process p = Runtime.getRuntime().exec("Command");
BufferedReader input =
new BufferedReader
(new InputStreamReader(p.getInputStream()));
while ((line = input.readLine()) != null) {
System.out.println(line);
input.close();
catch (Exception err) {
err.printStackTrace();
This sample program will list all the system log information....
