How to Use Exec function in Java Code

How to Use Exec method
I want to Execute command
net Start "some service"
using exec method of runtime class
or i use some other way if suggest

Assuming you have read http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html#exec(java.lang.String) already, I can only suggest to be more specific in what your problems are. If you are after just some example code, then download ftp://ftp.ebi.ac.uk/pub/software/textmining/monq/monq.tar.gz and have a look at the source code of monq.stuff.Exec. It does all those things which are necessary to keep track of a Process after it was created with exec.

How to use Oracle objects in java code

Hi all!
I'm reading an xls and i need to fill me oracle objects with java code:
OBJECT_NAME OBJECT_TYPE
LETTURA_OBJ TYPE
LETTURA_OBJ TYPE BODY
In the past weeks i've been using both java code into oracle and oracle objects, but new i need to write those objects with data i read with java, anybody can help me?
I know that the easiest work around would be to put the data i read from the excel file into a table and then fill the oracle objects, but now i want to learn how to write directly those objects with a command like the following one:
a sample of the code i'm tryng to write:
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED REPORT."Manage_Excel_ASMBS" AS
import java.io.*;
import java.io.IOException;
import jxl.*;
public cass ....

How to use odi variable in java code.

Hi,
I am trying to calculate check sum of a file and need to capture that in a odi variable...
I wrote code like this(selected technology as java bean shell)
<@
import java.io.*;
import java.util.zip.*;
public class checksum {
public static void main(String[] args) throws Exception {
FileInputStream fis = new FileInputStream(new File("c:/dummy.txt"));
CheckedInputStream cis = new CheckedInputStream(fis, new CRC32());
BufferedInputStream in = new BufferedInputStream(cis);
while (in.read() != -1) {
#checksum = cis.getChecksum().getValue();
}@>
But I am not able to get that value...
I tried in another way like this
<@
import java.io.*;
import java.util.zip.*;
public class checksum {
public static void main(String[] args) throws Exception {
long result;
FileInputStream fis = new FileInputStream(new File("c:/dummy.txt"));
CheckedInputStream cis = new CheckedInputStream(fis, new CRC32());
BufferedInputStream in = new BufferedInputStream(cis);
while (in.read() != -1) {
result= cis.getChecksum().getValue();
@>
In odi variable refreshing mode i selected schema as memory_engine and wrote
select '<@=result@>' from dual;
even this wont work for me :(
Anyone pls help me in this...
Thanks in advance
Pavan

Hi Phani,
Thanks for the reply. I resolved this. The mistake is I wrote java code in a class,in main function. I removed class and main function. Now I am able to capture value into Odi variable...
I modified code as
<@
import java.io.*;
import java.util.zip.*;
long result;
FileInputStream fis = new FileInputStream(new File("C:/dummy.txt"));
CheckedInputStream cis = new CheckedInputStream(fis, new CRC32());
BufferedInputStream in = new BufferedInputStream(cis);
while (in.read() != -1) {
result=cis.getChecksum().getValue();
@>
finally retrieving result value from dual
select '<@=result@> from dual

How to use the XULRunner with JAVA Code

Hi, all
I have a big problem about XULRunner. I can not find a nice solution on the internet. So I have to request you to give me some ideas.
We know the XULRunner is nice solution when we want to embed a browser into desktop program which is thunderbird, firefox and so on.
My questions are the following:
1. Can I execute a Java function accross the JAVASCript? We can execute javascript code in the JAVA, but I'm not sure I can do opposite it.
2. What is javaxpcom?
If you did program like this, please give me some ideas, thanks very much.

I marked this as "off-topic" since it's not a Firefox support question.
Another place for discussion related to XULRunner, besides the Mozilla community links at https://developer.mozilla.org/en-US/docs/Mozilla/Projects/XULRunner might be one of the [http://forums.mozillazine.org/ MozillaZine forums], such as the Mozilla Development forum:
*http://forums.mozillazine.org/viewforum.php?f=27
EDIT: I'm leaving this question open since it's about another Mozilla product and I'm escalating it to the Helpdesk in case anyone over there has a suggestion.

How to use protected method in jsp code

Could anyone tell me how to use protected method in jsp code ...
I declare a Calendar class , and I want to use the isTimeSet method ,
But if I write the code as follows ..
========================================================
<%
Calendar create_date = Calendar.getInstance();
if (create_date.isTimeSet) System.out.println("true");
%>
============================================================
when I run this jsp , it appears the error wirtten "isTimeSet has protected access in java.util.Calendar"

The only way to access a protected variable is to subclass.
MyCalendar extends Calendar
but I doubt you need to do this. If you only want to tell if a Calendar object has a time associated with it, try using
cal.isSet( Calendar.HOUR );

it gives error message... how can � use struct model in java applets???
if you help me i will be greatfull....

� use import but it doesn't work.
i add: import renk; or import class renk;
how will � add import I assumed based on your initial post that the renk and benek classes were in the same file. Apparently you're saying they are not. So for another thing, make your renk class "public class renk", and add the "public" keyword to the 3 members of that class. Then if your code still doesn't see the "renk" class, it would just be that you don't have the directory that contains the compiled "renk.class" in your classpath.

Search information using a VO by java code..?

Search information using a VO by java code.
Hi to all
Im trying to retrieve specific information by java using the VO object that I have attaché to the EO. I need to know if this is possible and how to.
For example lest say that I have the following information user name and password and I wand the telephone and other information.
Can some pls help me with a link of an example of how to do this.
Tanks to all.

Hi JulianeE
Yes it is possbile, please generate the VORowImpl file on the corresponding VO object. Even if your query return multple rows, it can . see the sample code below
OAViewObject vo1 = (OAViewObject)am.findViewObject("EmployeeEOVO1");
vo1.reset();
if (vo1 != null)
do
if(!vo1.hasNext())
break;
vo1.next();
EmployeeEOVORowImpl lcerl = (EmployeeEOVORowImpl)vo1.getCurrentRow();
lcerl.getFullName();

How to use host variable in Java?

How do I use host variable in java? I am getting SQL code of -404 and description of SQL code is The UPDATE or INSERT statement specifies a String that is too long column-name SQLSTATE=22001. Below is my code:
* i n s e r t M e s s a g e

public final Collection insertMessage(String businessId,String messageNumber,String messageType,

String approverId,String lastUpdateId,String longMessage) {
MessageTransport msi = new MessageTransport();
PreparedStatement ps = null;

Connection connection1 = null;
ArrayList list = new ArrayList();
try {

int k = len % constant; //k will hold value that has number of loops including initial insert.

return list;
if my longMessage is smaller like one line then everything works fine, but as soon as my longMessage if greater than 254 it starts giving me -404. How do I work around or Is there any way to use host variable in Java?
All kind of help is appreciated. Any question then please email me at [email protected].
Thank you.

This is what you got to do to insert a larger value.
//Assuming that message length is less than 254+ 254 characters.
//If larger then run the update loop that many times.
String longMessage = "Blah blah ... ";
String firstPart = "";
String secondPart = "";
int messageLength = longMessage.length();
if (messageLength > 254)
     try
          firstPart = longMessage.subString(0, 253);
          secondPart = longMessage.subString(254, message);
     catch (IndexOutOfBoundsException e)
//In the first insert set the first 254 characters
ps.setString(1, firstPart);
int result = ps.executeUpdate();
if (result != 0)
       System.out.println("Insert sucessful ");
       if (messageLength > 254)
            //now update with the second part.
            static String UPDATE_SECOND_PART = UPDATE my.table SET LONG_COL = LONG_COL || ? WHERE KEY_COL = ?;
            ps2 = connection.getPreparedStatement(UPDATE_SECOND_PART);
            ps2.setString(1, secondPart);
            ps2.setString(2, businessId); //assuming that businessId is the primary key.
            int result2 = ps2.executeUpdate();
            if (result2 != 0)
                  System.out.println("Update sucessful ");
            else
                 System.out.println("Update failed ");
else
       System.out.println("Insert failed ");
}Hope this helps.
