You might improve your chances of getting help if you do two things:
1) Explain what "not working" means.
2) ChangeSystem.out.println(IOEx); to IOEx.printStackTrace(); (in the eventhat is in fact related to "not working").

How to execute .sql file using ODI

Hi All,
I need to execute .sql file using ODI.
I tried @{path}{file} command in ODI procedure selecting oracle technology.but it is failing.
Do any one have any other idea to execute .sql file.
Thanks in advance

Ohk...I think you can try creating batch file(.bat) if its Windows & call that from ODIOSCommand.
The bat file should contain scripts which call .sql file using sqlplus & there you can use @{path}{file} format.
See if this helps.

You can execute .exe files in JAVA using the following code.

How to execute Bat Files using Jobs?

Hello, can anyone help me?
I have created a job like this, but it's not working:
begin
dbms_scheduler.create_job(
job_name => 'job_test'
,job_type => 'EXECUTABLE'
,job_action => 'C:/temp/test.bat'
,start_date => '01/DEC/2006 08:30 AM'
,repeat_interval => 'FREQ=DAILY'
,enabled => TRUE
,comments => 'Demo for job schedule.');
end;
begin
DBMS_SCHEDULER.run_job (job_name => 'job_test',use_current_session => false);
end;
Thx!

Hi,
This will not work because a batch file is not directly executable. It is executed using cmd.exe .
So what you need to do is to set c:\windows\...\cmd.exe as the job_action and then as your arguments set
/q
/c
c:\test.bat
then enable the job. This should work.
Also make sure the job scheduler service is setup and started (it needs to be started for external jobs to run).
There is an example given by scotttig in this thread
Re: dbms_scheduler
Hope this helps,
Ravi.

How to generate .xsd file using jaxb generated java files

Hi,
We need to upgrade our applicatio to jdk1.6 which has jaxb2.0 class files in it. Our application has java files generated from .xsd using jaxb1.0.2 version. At present we dont have .xsd or .xml file with us.
We decide to generate .xsd file by using jaxb1.0.2 generated java files. I tried using schemagen.exe given by jdk1.6 to generate .xsd file. It error out. Is there any other way to generate .xsd file ?
pls let me know.
thanks,
Thiru

Object-XML mapping is a new feature in JAXB 2.0. Classes generated with JAXB 1.0 won't generate a schema.

How to execute sh file of unix in java

iam trying to execute a sh file in target machine which will startup the database from source machine..
sh file is ..
# Synopsys
# This program startup's the database.
# Parameters
# @1: tuserconnect
# @2: tenvfile
# @3: tUserHome
progname=ajstartdb
echo "ssh ${1} . ${2} \&\& ${3}"
ssh ${1} . ${2} \&\& ${3}/ajss/sql/ajstrtdb.sh
retval=$?
echo "DEBUG::${progname}--> Completing execution with return code: $retval" > $progname.out
If i try to execute this ajstartdb.sh file in target itself it is executing perfectely.So i think no prob's with sh file..
but when i try to execute this sh file from java.. the process control is remaining in the prgm itself even after the cmd is executed.. i mean prgm is not exiting.
java prgm is :
import java.io.*;
class StartShut1
public static void main(String[] args)
try {
String cmd="ssh [email protected] . /d03/AppsGOLD/golddb/9.2.0/GOLD_hydapps.env \\&\\& /home/oragold/ajss/ajstrtdb.sh";
                         System.out.println(" the cmd is: "+cmd);
     Process p =Runtime.getRuntime().exec(cmd);
     int i = p.waitFor();
     System.out.println("Exit value of process is "+j);
                         System.out.println("Output of the Cmd is : "+i);
     String s=null;
     if (i!=0){
                              System.out.println("ERROR in executing the command");
                              BufferedReader cmdr = new BufferedReader(new InputStreamReader(p.getErrorStream()));
     while ((s = cmdr.readLine()) != null) {
                                             System.out.println(s);
                                                  s = null;
     BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
                                   // read the output from the command
                                   s=stdInput.readLine();
                         System.out.println(s);
     while (s!= null)
     System.out.println(s);
InputStream in = p.getInputStream();
int ch;
StringBuffer sb = new StringBuffer(512);
while ( ( ch = in.read() ) != -1 )
{ sb.append((char) ch); }
System.out.println("output from string buffer"+sb);
}catch(Exception e)
System.out.println("ERROR :"+e);
e.printStackTrace();
}//main

Kindly Reply me if u get an idea

And also u hv specified & in the cmd ... it is executing when we specify \&\& there.
Do u hv any idea ragarding this symbol (\&\&) in unix..Let us try first without vowels (the OP tends to drop them):
& n cmmnd prmpt wll trmnt th cmmnd nd rn t n th bckgrnd.
&& wll wrk lk n C (r Jv fr tht mttr): t wll vlt th frst trm nd g n xctng nd vltn
g f t ws "tr", tht s, f t yldd "zr" s rtrn cd.
For the faint the one with vowels:
& in a command prompt will terminate the command and run it in the background.
&& will work like in C (or Java for that matter): it will evalute the first term and go on executing and evaluating if it was "true", that is, if it yielded "zero" as return code.
Thus
posman@proli:~/ivan/fnt> test -d mydir && ls -l mydir
posman@proli:~/ivan/fnt> mkdir mydir
posman@proli:~/ivan/fnt> ls >mydir/1
posman@proli:~/ivan/fnt> test -d mydir && ls -l mydir
total 4

How to print PDF files using java print API

Hi,
I was goign throw lot of discusion and reading lot of forums related to print pdf files using java api. but nothing seems to be working for me. Can any one tell me how to print pdf files using java api.
Thanks in advance

Mike,
Can't seem to get hold of the example described in your reply below. If you could let us have the URL to get then it would be great.
My GUI application creates a pdf document which I need to print. I want to achieve this using the standard Java class PrinterJob (no 3rd party APIs I'm afraid, commercial restraints etc ..). I had a stab at it using the following code. When executed I get the pretty printer dialog then when I click ok to print, nothing happens!
boolean showPrintDialog=true;
PrinterJob printJob = PrinterJob.getPrinterJob ();
printJob.setJobName ("Contract.pdf");
try {
if (showPrintDialog) {
if (printJob.printDialog()) {
printJob.print();
else
printJob.print ();
} catch (Exception PrintException) {
PrintException.printStackTrace();
Thank you and a happy new year.
Cheers,
Chris

Executing *.xml files as *.jsp files

Under other web containers this usually takes about 4 lines in a config xml file.
I am still hunting through the online doco
but I was wondering if anyone could point
me to the relevant section quicker ? ...
Basically what I am looking to do is to
tell the server to parse and execute *.xml
files as *.jsp files. It should be a simple
mapping somewhere in the config files.
Thankyou in advance,
Brian.

Chuck,
That isn't quite what I want to achieve. What I have done
elsewhere is place the following servlet mapping in the Web
Container's web.xml file.
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.xml</url-pattern>
</servlet-mapping>
which then causes all *.xml files to be processed as *.jsp files.
Servlet name being the name of the servlet that processes the
JSP files for the web container. Is there an equivalent
thing under BEA ? Does BEA have a servlet which processes
JSP files or does it use something different ?
Cheers,
Brian.

Brian,
You should be able to update the web.xml for this purpose
e.g.
<servlet>
<servlet-name>myFoo</servlet-name>
<jsp-file>SnoopServlet.xml</jsp-file>
</servlet>
See the following URL for a more detailed description
