How to open external files in a Java stored procedure?

Hi y'all,
I'm trying to open an external text file from a Java stored procedure. The java sp has been successfully loaded, resolved, published, etc. in Oracle. I'm using the following statement to try to open the file (enclosed in a try/catch block):
BufferedReader fileObj = new BufferedReader(new FileReader("fileName.txt"));
I'm getting a file not found error. Where is Oracle looking (i.e., what directory)?
Your help is greatly appreciated,
Gary

Hi Gary,
you must use a "database directory", e.g:
SQL>create directory WORKING_DIR as '/home2/common/';
SQL> select * from all_directories;
OWNER DIRECTORY_NAME
DIRECTORY_PATH
SYS WORKING_DIR
/home2/common/

Open a file into a java app - HOW DO YOU DO IT!!

I have written an html/php editor - I want to set it up so that when you double click on a php file in windows it will open the file into my java ide.
I know this can be done - but how!!! There does not seem to be any info on the web about it - can anyone give me some pointers.
Thanks

Yeah - but the problem is: You can only set files to
open with a .exe file - if you go to the settings and
set the .php file to "open with" you have to select a
.exe file e.g. notepad.exe
However you can't create .exe files in java!!!! So how
do you do it?You have to spend $$$'s
However many /most converters don't work without the relevant updated JVM (but they are *.exe, kind of)

I can`t open jar files though my java version is updated

Hello everybody, I`m using Macbook Pro 13` with Lion on it.
As it says in the title, I can`t open jar files though, my java version is updated.
It says, I shuld check the console.
Right now, my java version is, "1.7.0_15", and i`m trying to open a jar file created 3 days ago, by some developer.
Although, if im trying to open jar file created 1 year ago, it doe`s open.
Why is that? and, How can i fix it?
Thanks.

With Java 6 and prior, you had to enable logging first before you could view error messages in Console. I am guessing that you need to check the Java Control Panel to see if logging is turned on.

How to use .properties files in Webdynpro Java code?

Hi all,
I want to use a logon.properties file when I initial a JCO connection pool in my webdynpro DC (JCO.addClientPool()),but I found when I deployed this DC to the server, it always giv e me an FileNotFoundException. So I donot know how to deploy a .properties file to the server and how to access this file in my Java code?
Thans and Best regards
Deyang

Hi,
1) put .properties file to your packege under src\packages folder (src\packages\com\sdn\properties\jco.properties)
2) load property:
     final InputStream is = getClass().getClassLoader().getResourceAsStream("com/sdn/properties/jco.properties");
     final Properties properties = new Properties();
     try
          properties.load(is);
     catch(Exception e)
          wdComponentAPI.getMessageManager().reportException(new WDNonFatalException(e), false);

How to compile and run a .java file from another java program

hello,
can any one tell me how to compile and run a *.java* file from another java program which is not in same directory?

Well a smarter way of implementing this is by using a solution provided by Java Itself.
If you are using J2SE 6.0+ there is an in built solution provided along with JDK itself and inorder to go ahead with solution the below are set of API which you;d be using it for compiling Java Programs (Files)
http://java.sun.com/javase/6/docs/api/javax/tools/package-summary.html
How do i do that ??
Check out the below articles which would help you of how to do that
http://www.ibm.com/developerworks/java/library/j-jcomp/index.html
http://www.javabeat.net/javabeat/java6/articles/java_6_0_compiler_api_1.php
http://books.google.com/books?id=WVbpv8SQpkEC&pg=PA155&lpg=PA155&dq=%22javax+tools%22+compiling+java+file&source=web&ots=XOt0siYe-f&sig=HH27ovuwvJgklIf8omTykUmy-eM
Now once we are done with compilation.In order to run a Specific class all you ought to do is create an object and its specific methods of a specified class included in the CLASSPATH which you can manage it easily by usage little bit reflections.
Hope that might help :)

Hi Ram,
Following information might help you to resolve the issue.
After logging into Desktop Intelligence, you may be presented with a message stating:
u201CYou have received 1 document from users"
Examining the Inbox from within the Desktop Intelligence client shows no objects visible in your Inbox.
The object in your Inbox is in a format other than Desktop Intelligence format such as, PDF, XLS or other format. Therefore the object is not recognized by the Desktop Intelligence client inbox browser.
Log in to Info View or the Central Management Console, browse to your Inbox and verify the file name and format that has been sent to your Inbox. The object may be saved, copied, moved or deleted as necessary.

How to open a file created at the server through form/report at client end

How to open a file created at the server through form/report at client end
Dear Sir/Madame,
I am creating a exception report at the server-end using utl file utility. I want to display this report at the client end. A user doesn't have any access to server. Will u please write me the solution and oblige me.
Thanks
Rajesh Jain

One way of doing this is to write a PL/SQL procedure that uses UTL_FILE to read the file and DBMS_OUTPUT to display the contents to the users.
Cheers, APC
