Hi,
How can I input an excel file into the java servlet program? I am using POI HSSF programming to read the content of that excel file.I have created a form that will accept the path from the user and in the servlet program, I have called a post method to retrieve the path of the file. I am getting the path of the file as a string.Then I have to access the file to read the data. But it is not working. What should I do?.Please help me.
I have created an html file to create a form that will ask the path of the file to be loaded into the servlet program.Please give me a solution,thanks in advance. The servlet program that receives the file is shown below. It just only take the name of the file and prints if that is ok.

How to customize the Java Concurrent Program(PO Output for Communication)
I need to add the Line level Ship To Address ,Line Notes and Extended Price fields on Java Concurrent Program.
Please any body help/guide me in this regard.

Hi,
Changing Java Conc. program for "PO Output for Communication" is difficult.
Actually, if you observe closely, "PO Output for Communication" program uses PO<HEADER/LINES..>_XML views.
So if you could change these views and add your requireed columns to it, you can automatically see your changes in XML data file.

Application Server 4.0 caching the Java Servlet Program

Hi all,
I am working with Oracle8i databse and Oracle Application Server 4.0. Now I need to develop some Java Servlet's Program. I successful configure the server and my Servlet program can connect to the Oracle database.
However, when I make some modification to the program and recompile it. The browser cannot refresh to the modified program. This mean that the content is't update. I think the reason may be the previous program is cached in server.
Later, I discover using the 'owsctl' utility to reload the application server can solve this problem. However, it is quite inconvenience and not favour to reloasd the server very frequently. And I guess there may have some configuration parameters in the 'OAS Manager' can help me to solve my problem.
So, anyone can tell me how to solve this problem? Thank you very much.
Regards

OAS 4.0.8.1 supports servlets. You need a patch if you implement extra path info feature of servlets. In addition, you have to bounce OAS everytime you upload new servlets. This behavior does not follow the Servlet spec and I don't know when Oracle will fix it. It is a big problem for sites trying to run 24x7.

Help needed in executing the java/jsp program from UCM .

I have a .jsp program running in my Jdeveloper which when executed pops a window to browse and select files and with few custom options .
But i want to execute that Program from within UCM (create a new jsp page in UCM OR provide link ? i am not sure .... ) , could anyone help on how i can execute/run the program from UCM ?
thanks in Advance
Plaxman

If your jsp makes use of jars you may want to look into using a WAR instead. You can check the WAR into content server and there is even a link on the administration page for JSP Web App Admin. Treating the JSP(s) and jar(s) as an entity may be a more successful path for you.
You can find some jsp examples and ever a war example in this directory: <install root>\samples\JspServer

Error occurred during execution of java concurrent program in R12.2 instance

Hi All,
The R12.2 instance is a cloned instance. I am getting the below error while compiling the java concurrent program in R12.2 instance.
Has anybody had this error before?
Any help or advice will be really appreciated.
Thanks in advance.
Kind regards,
Ranjan

Hi,
The error could be because of the XSD attributes.
In the Source message CustomerDetails, check the XSD attributes of the DataType CustNumber in the 'Detail' column in the IR. For example, it may have a pattern or whiteSpace or some other attribute.
Then check the input file contents for the CustNumber node. One of those values may not match these attributes.
Hope this helps,

Java Concurrent Program issue

Hello,
I am fairly new the Java Concurrent Programs concept. I was just trying a simple Hello World example but I cannot seem to run it from the operating system. Here is my Hello World java program I created using Jdeveloper:
package oracle.apps.fnd.cp.request;
public class Hello implements JavaConcurrentProgram {
public static final String RCS_ID = "$Header$";
public void runProgram(CpContext ctx) {
ctx.getLogFile().writeln("-- Hello World! --", 0);
ctx.getOutFile().writeln("-- Hello World! --");
ctx.getReqCompletion().setCompletion(ReqCompletion.NORMAL, "");
It compiles fine in Jdev generating the class file. Here is what I did :
1) Created directory under $JAVA_TOP as follows :
mkdir $JAVA_TOP/oracle/apps/fnd/cp/sample
2) moved the Hello.java file there under sample directory
3) compiled java file using avac $JAVA_TOP/oracle/apps/fnd/cp/sample/Hello.java ( It compiles fine generating the class file )
4) Now I wanted to test running it : I tried using jre command first as I saw in other posts but this is not working :
jre -Ddbcfile=$FND_TOP/secure/k021kp-6180_r115dev1.dbc -Drequest.outfile=/export/home/sqadri/outfile oracle.apps.fnd.cp.request.Run oracle.apps.fnd.cp.sample.Hello
Error :
ksh: jre: not found
Then I tried using the other way I saw on posts which is using the java command :
java -cp $AF_CLASSPATH -Ddbcfile=$FND_TOP/secure/k021kp-6180_r115dev1.dbc -Drequest.outfile=/export/home/sqadri/outfile oracle.apps.fnd.cp.request.Run oracle.apps.fnd.cp.sample.Hello
This gives me the following error :

Can anyone tell me what I am doing wrong ? I have tried everything even tried ftp the class file from my local but I get the same error. Any help would be appreciated.
Thanks

Ajay,
Yes you are right. I did not register my java program yet in the concurrent programs.
I thought I could test it out from the operating system command line before registering it. But looking at your document you sent me it seems I have to do all the steps i.e. define concurrent program etc before I can test it from the operating system. If that's the case then what's the use of trying to test it via operating system using
java -cp $AF_CLASSPATH -Ddbcfile=$FND_TOP/secure/k021kp-6180_r115dev1.dbc -Drequest.outfile=/export/home/sqadri/outfile oracle.apps.fnd.cp.request.Run oracle.apps.fnd.cp.sample.Hello
Thanks

PL/SQL log messages are not printing from Java concurrent program

Hi,
I have a strange issue while submitting the Java concurrent program through PL/SQL.
I have a PL/SQL concurrent program which will invoke the Java concurrent program inside the package by use of "FND_GLOBAL.SUBMIT_REQUEST". It worked and submitted successfully. From that Java concurrent program we are calling some other PL/SQL packages and printing some log messages over there. But problem here is the request is only printing the Java log messages in view log but not the PL/SQL log messages. But if I submit the Java concurrent program directly from SRS form at that it is printing both Java and PL/SQL log messages.
I am just wondering how the log messages has not printed. Please provide your inputs to solve this problem.
Thanks
Suriya

Invoke Java Concurrent program from PL/ SQL

Hi Experts,
I 've a requirement to invoke a Java Concurrent program form PL/ SQL. I 've defined default values for some of the parameters in the Java Concurrent program definition and some parameters do not have a default value. I would like to provide only the mandatory attributes that do not have a default value set from my PL/ SQL code. Can you please suggest how this can be achieved?
I tried giving null for those attributes. But, the java program takes a "" value instead of the default values. Any inputs here will be immensely helpful.
Thanks,
Ganapathi

Updating the correct format to be used for reference:
The correct format is:
fnd_request.submit_request(
application => 'PDT_CODE',
program => 'PGM_NAME', --program IN varchar2 default NULL,
start_time=> SYSDATE, --start_time IN varchar2 default NULL,
sub_request => FALSE, --sub_request IN boolean default FALSE
argument1 => rowdata,
argument2 => xxx
Note: the parameter name should be "argument1...n" (and not the actual argument name).
But I noticed that for parameters that are missed out, the default values still do not take effect. Can anyone please confirm this behavior?
Thanks,
Ganapathi

How to pass input parameter (parameterized mapping) to java mapping program

Hello
I have a question about the parameterized mapping with Java (PI 7.1).
In the operation mapping (using Java-class) I defined a inputer parameter (string). I think I am supposed to retrieved the value using:
arg0.getInputParameters().getString("myInputParameterName");
where arg0 is the TransformationInput object.
However I am not able to get the value, I got runtime exception saying the inputer parameter doesn't exit.
Then I figured out maybe I need to bind the OM input parameter to Java mapping parameter, just like in case of message mapping, you need to bind OM parameter to MM parameter. However there is no way to define input parameter for the java mapping program.
Anybody has done java mapping with parameterized mapping?
Anybody can give any hint for this?
Thanks
Jayson

InputParameters params = container.getInputParameters();
DynamicConfiguration conf = (DynamicConfiguration) params.getValue(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
