Is it possible to call the java compiler javac from runtime

Hi, can someone tell me if it is possible to call javac from runtime. I need to do this because the class I need to compile must be filled with some data given by the user. I plan to write the class code in a file, let the user write some code lines at runtime, add this lines to the file and then call javac in order to compile the file and check if the user wrote his lines properly. I wonder if this makes sense, thanks for reading this and for your help.

You can try using the exec method in the class java.lang.Runtime, but here are some traps to watch out for when using it:

Is it possible to call the SQL Server DB from jsp to java?

im doing a configurable system where you can create your own table using the system. i can do the creation of table by running the statement CREATE TABLE...........(with attributes) in java.
Let's say i have created tblST1 with attributes st_ID, st_Name, st_Description.
My problem is i dont know if it's possible to retrieve all the attributes from jsp to java.

jverd: i need your help. Iv read all the links u posted but im having a hard time in understanding them.
For the site http://java.sun.com/j2se/1.4.2/docs/api/java/sql/ResultSetMetaData.html , there's a code there which is...
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount();
boolean b = rsmd.isSearchable(1);
what i did was, i inserted it in my java code which is :
public boolean checkFieldTable2()
          boolean checked = false;
          try
               IRMS_DBConnect db = new IRMS_DBConnect();
               db.openCon();
               ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
          ResultSetMetaData rsmd = rs.getMetaData();
          int numberOfColumns = rsmd.getColumnCount();
          boolean b = rsmd.isSearchable(1);
               db.closeCon();
               checked = true;
          catch (Exception ex)
               System.out.println("Error on Execution: " + ex);
          return checked;
and i compiled it and there was an error that the variable stmt was not initialized. Am i doing the right way?
Can anyone help me pls? pls pls pls

Is it possible to disable the optimized compiler in LabVIEW 2010

Hello,
I have a project that take 3 minutes in LabVIEW 8.6 to build and now with LabVIEW 2010 it take 10.5 minutes. 3x more longer.
In fact my project as 61 .lvproj for a total of 4300 vi's that take 1 hour to build. If I interpolate, the entire build process will take 3 hours in LabVIEW 2010. This is not acceptable
I know that the new compiler optimize the code for better performance, but if I don't need better performance.
Is it possible to disable the optimized compiler in LabVIEW 2010 with an INI key in LabVIEW.ini.

One Application Builder setting you might try out to make builds go much more quickly is the Remove Unused Members of Project Libraries checkbox and the Modify Project Library File after Removi....
This can drastically cut down the build times. Note, however, that this option does not work well if your application will load external plug-in VIs when it runs, because the libraries of those plug-in VIs may conflict with the modified libraries in the executable file. If you don't have a plug-in architecture, this will not affect you.
The "Remove unused members of project libraries" was already selected but not the "Modify project library file after removing unused members" and selecting this cut the build time from 10.5 min to 4 min.
Thank you Jarrod for this tips

Can we call a Java Stored Proc from a PL/SQL stored Proc?

Hello!
Do you know how to call a Java Stored Proc from a PL/SQL stored Proc? is it possible? Could you give me an exemple?
If yes, in that java stored proc, can we do a call to an EJB running in a remote iAS ?
Thank you!

For the java stored proc called from pl/sql, the example above that uses dynamic sql should word :
CREATE OR REPLACE PACKAGE MyPackage AS
TYPE Ref_Cursor_t IS REF CURSOR;
FUNCTION get_good_ids RETURN VARCHAR2 ;
FUNCTION get_plsql_table_A RETURN Ref_Cursor_t;
END MyPackage;
CREATE OR REPLACE PACKAGE BODY MyPackage AS
FUNCTION get_good_ids RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'MyServer.getGoodIds() return java.lang.String';
FUNCTION get_plsql_table_A RETURN Ref_Cursor_t
IS table_cursor Ref_Cursor_t;
good_ids VARCHAR2(100);
BEGIN
good_ids := get_good_ids();
OPEN table_cursor FOR 'SELECT id, name FROM TableA WHERE id IN ( ' | | good_ids | | ')';
RETURN table_cursor;
END;
END MyPackage;
public class MyServer{
public static String getGoodIds() throws SQLException {

HT5071 Is it possible to call a locally installed ibook from a hyperlink? What about to a bookmark?

Is it possible to call a locally installed ibook from a hyperlink? What about to a bookmarked page?
I have 2 questions..
1. Can I send a link via email that when launched will open an ibook that has already been downloaded to the bookshelf?
2. If question 1 is possible, can I take it a step further and call a bookmark, i.e. chapter 3.
Our company has it's own appstore and I want to send out links to sections of the ibooks using bookmarks or at the very least take them to the start of the ibook.
I don't need to give them a link to install the ibook as they already have it installed.
Any help would be much appreciated.
Chris.

That would be cool, but it's not possible. The ibook is not accessible by URL in the user's bookshelf.

Calling the super class method from the subclass

Hi all,
I have a question about inheritence and redefinition of methods. Is it possible to call the superclass implementation of a method which is redefined in the subclass in another method of the subclass?There are possbilities like creation of an explicit super class instance or delegating the super class method implementation to another method which is also protected etc. What i mean is, is there a direct way of calling it?We have ,me, as the reference for the instance we have(which is the subclass instance in this case), is there also a way of pointing the superclass implementation(with super we can reference in the subclass redefinition, my question is if we have such a parameter in other methods of the subclass too)
Thanks in advance
Sukru

Hi,
The super reference can only be used in redefined methods to call superclass implementation . So probably what you can do is use upcasting and access the required superclass implementation. I can think of only this way...;-)
Ex data lr_super type ref to cl_superclass
lr_super = lr_subclass.
lr_super->method().

Is it possible to show the shell in linux from exec

my app needs something to be installed on the client pc. It downloads the file and then install its automatically. For win this is working, fir the linux not, i can set the permissions, and when i try to launch it like
String[] commands = {"/bin/sh","filename.bin"};
Runtime.getRunTime().exec(commands);
it starts, but it hangs. I think it's possible due to the fact that's there a license agreement in the bin file. when i true to install it manually, from the shell, it shows me the license agreement. i think that linux is waiting for input from the user and my prog hangs. so Is it possible to show the shell in linux from exec ??? so that the user can see the license agreement

it is in fact the same as the bin file for installing
java, when you extract that you see the license
agreement and the user has to press enter to go on,
that's the only input.
You're right, i should read the out and err, i
forgot, stupid of meYou have to send enter to the input stream of the process in that case.
