How to invoke from UNIX script and pass back return code?

Though I am an experienced developer, I am new to java. I created a class containing a single method. I have performed my testing by running the class class.method from the command line in a UNIX (Solaris) environment. Now, I would like to have the class.method invoked from a UNIX shell script, and to return a success/failure indicator from the method, to the UNIX script. I modified the method to make it return char, rather than being defined as void. Within the class and method, I declared and initialized a char variable. I added a finally clause which contains a single return statement, returning the char return code variable. Within my UNIX script, I invoke the class/method as follows:
return_code = java myClass
This does not seem to be invoking the method however. Can someone please tell me what I am doing wrong? Or is more information needed in order for someone to help me out.
Please let me know.
Thanks.

stdunbar,
Using your suggestion of System.exit(retVal); seems to allow the java method to be performed successfully (Thank You). But I am still having a problem with the value being recognized by the shell script.
In my script, I'm doing the following:
java MyClass inputparameter > return_code
export return_code
echo $return_code
But return_code does not seem to contain a value. Just before the System.exit(retVal); I added System.out.println("return code = " + retVal ); and I can see that retVal. When I run the java method outside of the UNIX shell script, I can see that retVal does indeed contain a value. So I think my problem might actually be the code in the UNIX script.
Thanks again.

How to read from input file and pass to script

How can I get rid of the hard coded PATH statement and feed script based upon text file input.
Input is contained in a file..
'C:\cntprocess\ called sistemfolder.txt that has 2 fields folder
then shortname.
example:
C:\cntprocess\REW1___1~Rew1
C:\cntprocess\REW2___1~Rew2
I want the first part in each record passed to script for processing
C:\cntprocess\REW1___1
C:\cntprocess\REW2___1
Pass those values to this Script: I want values from above passed to the $Path
$path='C:\Sistemi\'
get-childitem -path $path *.spx | % {
" Starting File Process....." >> $path\sistem.log
$PDate = get-date
$date = get-date -uformat "_%d_%m_%Y_%H%M%S.bak"
#"Set backup date to $date" >> $path\sistem.log
$newname=($_.fullname -replace ".spx",$date)
$file = [System.IO.Path]::GetFileNameWithoutExtension($_.fullname)
"File backup name is $newname" >> $path\sistem.log
Rename-Item $_.fullname $newname
"Renamed file to $newname" >> $path\sistem.log
$lines = get-content $newname
foreach ($line in $lines)
$line + " " + [System.IO.Path]::GetFileNameWithoutExtension($_.fullname) | Out-File "$path\sistem.csv" -append
Write-Host $_.fullname
"Files Processed on $PDate are $newname " >> $path\sistem.log
Thanks.

OK, I was mistaken a bit on what I originally told you. After you run the command of
$myFile = Import-Csv -Delimiter '~' -Path $path -Header Path, ShortName
$myFile is actually an array of PSCustomObjects, so you cannot access it like $myFile.Path, you will actually have to loop through the $myFile first, so try changing your script to be the following and see if that helps any
param
[string]$path
$myFiles = Import-Csv -Delimiter '~' -Path $path -Header Path, ShortName
# Then you can call it like so
$myFiles.Path #Returns just the path
$myFiles.ShortName # Returns the shortname
$path='C:\AreaSistemi1\'
foreach ($myFile in $myFiles)
get-childitem -path $myFile.Path *.spx | % {
" Starting File Process....." >> $myFile.Pathsistem.log
$PDate = get-date
$date = get-date -uformat "_%d_%m_%Y_%H%M%S.bak"
#"Set backup date to $date" >> $path\sistem.log
$newname=($_.fullname -replace ".spx",$date)
$file = [System.IO.Path]::GetFileNameWithoutExtension($_.fullname)
"File backup name is $newname" >> $myFile.Pathsistem.log
Rename-Item $_.fullname $newname
"Renamed file to $newname" >> $myFile.Pathsistem.log
$lines = get-content $newname
foreach ($line in $lines)
$line + " " + $myFile.ShortName | Out-File "$path\sistem.csv" -append
Write-Host $_.fullname
"Files Processed on $PDate are $newname " >> $path\sistem.log
Also looking at your script, you said your text file contained the format of <filePath>~<shortname> but I see you doing a $myFile.Pathisstem.log, where does the Pathisstem.log come from?

Tcl proc with input argument run from UNIX script...how

Environment:
OWB 10g Client on Windows XP Professional
Repository - 9.2.0.4 on UNIX (AIX 5.2)
Target - 9.2.0.4 on UNIX (AIX 5.2)
I need a little tcl advice, please!
I have a tcl script (proc, I guess) that takes one argument, in this case a mapping name.
I would like to execute this tcl script from a UNIX shell script and pass the name of the mapping as an argument to the UNIX shell script. Something like:
OMBPlus.sh omb_deploy.tcl $1
where omb_deploy.tcl is the script that has all the OMBPlus commands in it to create the deployment plan and execute it.
I'd like to pass the mapping name as a command line argument to the UNIX shell script but it doesn't like it.
When I execute the script as above, I don't see any output and the mapping does not get deployed.
So, I need a little help on two (2) issues:
1- How do I generate a log file of the output of the tcl script?
2- How do I pass the mapping name as an argument to the UNIX shell script?
For #1 I have tried using the 'open logfilename w' at the top of the tcl script but it produces no output.
I saw another example from this forum where the author used a 'putslog' command in the script. I can't find any documentation on that command, what does it do?
That same script set a global OMBLOG variable at the top of the script and used the 'putslog' command in the body.
Is OMBLOG some special reserved word for logging? I couldn't find anything on it.
I'm trying to learn tcl but struggling to put all the tcl stuff together with all the OMBPlus stuff and make it all work is getting the best of me.
Any assistance, with examples (I learn best from them), is greatly appreciated.
Gary

Well duh!
I ended up just logging everything from the UNIX shell script and letting the tcl script write everything to stdout.
I also finally found the $argv parameter and have used that to pick up the name of the mapping being passed to OMBPlus.
It seems to be working so far.

How can i run unix script from my apex page

how can i run unix script from my apex page and take the output of unix script as a hidden variable and display it on the report region of that page

I had a requirement to run a Fortran program against some data that woudl be extracted from the database after the user set up their filtering criteria and made some additional input. SInce the program was to complex to conver to PL/SQL, we decided to try and invoke it from Apex. This is how I did it.
1. I followed the steps in Tim Archer's excellent article "Oracle External Procedure to Run Host Commands" (http://www.timarcher.com/?q=node/9). If the link does nto work, google the article's title.
Using this steps I created a function which accepts any OS command, including calling my own shell scripts, and runs them. I called my PL/SQL function "shell" instead of "USF_RUN_HOST_CMD " as Tim did in his example (step 9).
2. In Apex,
a. I created a button to run my shell command. (I named it P2_RUN_SHELL)
b. I created a PL/SQL process whose source looks as follows:
shell('/home/ackness/scripts/cr_xcf_file.sh > /tmp/cr_scfp_file.log');
and which was conditioned on the the button P2_RUN_SHELL.
It works like a charm.
Note: since you can run your own scripts using this method, you can encapsulate a series of commands in a UNIX shell script and invoke that script from Apex. This allows you to be able to test or run you commands from the command line as well as Apex and makes it easier to develop/debug/enhance the scripts in the future.

How to open a page from a Form and pass parameters to the form on that page

I found a similar example on this forum, but it did not work for me:
declare
l_names owa.vc_arr;
l_values owa.vc_arr;
i number;
begin
PORTAL.wwpro_api_parameters.retrieve(l_names, l_values);
FOR i in 1..l_names.count
LOOP
htp.p(l_names(i) || ' ' || l_values(i));
END LOOP;
end;
By using this method i get the parameters for the Form, like the session ID, but not the parameters for the Page that the form is displayed in.
Another method I tried:
To open a Form from a Form and pass parameters works fine like this:
--In the After processing page PL/SQL event.
declare
v_id number;
blk varchar2(10):='DEFAULT';
Begin
v_id:=p_session.get_value_as_number (p_block_name=>blk,p_attribute_name=>'A_ID');
if v_id > 0 then
htp.formOpen('PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=2649500412&p_arg_names=_show_header&p_arg_values=YES&p_arg_names=ID&p_arg_values='||to_char(v_id),'post');
htp.formSubmit(NULL,'Upload Files');
htp.formClose;
end if;
End;
But I want to open a Page containing the Form instead of just opening the Form. Is this possible to open a Page and pass paramters to the page, and then let the form inside the Page access the passed paramters. The reason for this is that a Form cannot be based on a page template, or can it? When opening the form i want to keep the left menu, which I can if it is a page based on my template with the left menu.
Best regards
Halvor

Hi,
You can do this by calling the url of the page with the form. You can then use p_arg_names and p_arg_values to pass parameters. In the called form you can get the value from p_arg_names and p_arg_values and assign it to the form field.
You can call this code in the success procedure of the calling form.
declare
v_id number;
blk varchar2(10):='DEFAULT';
v_url varchar2(2000);
Begin
v_id:=p_session.get_value_as_number (p_block_name=>blk,p_attribute_name=>'A_ID');
v_url := <page_url>;
if v_id > 0 then
call(v_url||'&p_arg_names=id&p_arg_values='||v_id);
end if;
End;
In the called form in "Before displaying form" plsql section write this code.
for i in 1..p_arg_names.count loop
if p_arg_names(i) = 'id' then
p_session.set_value(
p_block_name => blk,
p_attribute_name => 'A_ID',
p_value => p_arg_values(i)
end if;
end loop;
This code picks up the value from p_arg_values and assigns it to the form field.
Hope that helps.
Thanks,
Sharmila

Unix Script and Jar files

I am in the process of designing a new system and wonder if the following is possible.
I want a UNIX script to execute a Jar file with a status of 1 or 0 (based of success/failure) being passed back from the Jar to the UNIX script.
I know a Jar file can be executed from a UNIX script but not sure about the passing of a message.
Would public static void main(String[] args) make it impossible to pass a message or is there some way around this ?
If a message can be passed back to the Script how would it pick it up ? - `echo $?` ?
Message was edited by:
palmeal

Right, in the shell script you have in $? the return
code of the last command.
java ...
if test $? -eq 0
then
echo java was ok
e
echo java oops
If a message can be passed back to the Script howwo
However the return code is no message.I really don't understand! Are you saying you just want to read something in the shell script that is generated by the Java program but the Java program must keep running and not terminate? If so then use stdout or stderr (as BIJ001 says).

Call tcode from alv report and passing group of values

hi all .
i want to call tcode from alv report and passing an internal table or group of values to a selection option of that t code ? how
ex. passing group of GL to fbl3n and display the detials of all .
thank you

Dear,
You have done a small mistake
--> rspar_line-option = 'EQ'.
rspar_line-HIGH = PDATE-HIGH.
u r passing "high" value and in "option u r passing "EQ" so how it will work!!!
So if u r passing only 1 date or more dates like 01.01.2010 , 15.02.2010 , 10.03.2010 then pass
rspar_line-selname = 'SO_BUDAT'.
rspar_line-kind = 'S'.
rspar_line-sign = 'I'.
rspar_line-option = 'EQ'.
rspar_line-LOW = PDATE-HIGH.
APPEND rspar_line TO rspar_tab.
or if u r passing low & high date means in range like 01.01.2010 to 30.01.2010, then pass
rspar_line-selname = 'SO_BUDAT'.
rspar_line-kind = 'S'.
rspar_line-sign = 'I'.
rspar_line-option = 'BT''.
rspar_line-LOW = PDATE-LOW.
rspar_line-HIGH = PDATE-HIGH.
APPEND rspar_line TO rspar_tab.
try above code , hope it helps...
i think u cannot use "call transaction using bdcdata" in ur case bcoz as u said in ur 1st post u want to display the details of all but still if u want to use then u should pass all parameters in loop.

DYNBEGIN
FNAM
FVAL
ex:-
LOOP AT GT_TEMP INTO GS_TEMP.
CLEAR bdcdata_wa.
bdcdata_PROGRAM = 'SAPXXXX'.

bdcdata_DYNBEGIN = 'X'.

CLEAR bdcdata_wa.

How do I get my photos and music back into new version iTunes from my iPad?

I have the new version of iTunes (11 0 2 26) for Windows which installed over my old copy. I see none of my music etc even after it claims to have synced and backed up. How do I get my photos and music back into iTunes from my iPad? It syncs OK with calendar and contacts from Outlook and I can force copying of apps and books but why does it not show music and photos in the iTunes library? help please.

Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. Note that in iTunes 11 an "empty" library may show your past purchases with links to stream or download them.
In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
Alternatively, depending on exactly when and why the library went missing, there may be a more recent .tmp file in the main iTunes folder that can be renamed as iTunes Library.itl to restore the library to a recent state.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!
Should you be in the unfortunate position where you are no longer able to access your original library, or a backup of it, then see Recover your iTunes library from your iPod or iOS device.
