You should not ask questions like this.
Did you try your problem by yourself? If so, what have you tried and what were the problems you faced in that?

Giving input to jtable from a database in runtime

friends
previously i have posted an query asking how to intilize the row size of jtable in run time for which i got good rewsponce to direct me to an page in sun/components,i read the jtable page in specifie link provided in sun,but i could not figure out how to give input to jtable from a database on runtime.In that page they have used by giving input in an array and then displaying it, by that they set the no of rows in the table ,but i want to set the row size based on number of records fetched from the oracle database.kindly guide me

What you need is to develop a table model which uses a database as the data source.

Giving input to the runtime process

Hi Friends,
I want to run the java debugger programatically through java. I started the debugger by creating a Runtime Process like:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import javax.swing.JPanel;
public class RunDebug extends JPanel
public static void main(String arg[])
Runtime execEnv = Runtime.getRuntime();
String command = "";
try
Runtime rt = Runtime.getRuntime ();
command = "jdb -connect com.sun.jdi.SocketAttach:hostname=localhost,port=8000";
Process process = rt.exec (command);
catch (Exception e)
e.printStackTrace();
The debugging process is started and it is ready for input, I have to give input the above same process. I searched for giving inputs to the Process class but I cannot. I tried this with batch file which contains all the commands but it is not running properly. Reply to me if you know the procedure. Thanks in advance.
Thanks,
Sangeetha.

Thank you for your reply pa. But I tried this already like this:
OutputStream fout= process.getOutputStream();
OutputStream bout= new BufferedOutputStream(fout);
OutputStreamWriter out = new OutputStreamWriter(bout);
out.write("locals");
I have given the next command to be supplied through OutputStream. But when I am reading the inputs in the Process like:
InputStreamReader reader = new InputStreamReader ( process.getInputStream () );
BufferedReader buf_reader = new BufferedReader ( reader );
String line;
while ((line = buf_reader.readLine ()) != null)
System.out.println (line);
But the output of the command that I gave through OutputStream is not printed. So I think the command which I gave through OutputStream is not properly recognized. If it is properly recongnized then I should get the output of that command when trying to read the input stream. Whether I am correct in writing the command through OutputStream??? Waiting for your reply...

Can I create a dynamic number of inputs during runtime?

Can I create a dynamic number of inputs during runtime?
Oracle 11g
Application Express 4.0.2.00.06
Here is my problem:
We have a table that holds metadata about files (hardcopy or softcopy files).
We expect we may need more columns in the table at some point and don't want to modify the table or the application.
So in order to do this I would like to create:
A table called TBL_FILE with the columns:
TBL_FILE_ID               NUMBER                (This will be the primary key)
TBL_FILE_NAME          VARCHAR2(1000) (This will be the name of the file)
A second table will be called TBL_FILE_META with the columns:
TBL_META_ID               NUMBER               (This will be the primary key)
TBL_FILE_ID               NUMBER                (This will be the forign key to the file table)
TBL_META_COLUMN     VARCHAR2(30)     (This is what the column name would be if it existed in TBL_FILE)
TBL_META_VALUE          VARCHAR2(1000) (This is the value that record and the 'would be' column)
So a person can have as much meta data on the file with out having to add columns to the table.
The problem is how can I allow users to add as much data as they like with out having to re develop the page.
Other things to note is that we would like this to be on a single page.
I know how to add we can create multi-row inserts by using a SQL Query (updateable report),
however the TBL_META_VALUE column in the TBL_FILE_META will sometimes be a select list and other times a text box or number field.
So I don't see now a SQL Query (updateable report) would work for this and I can't create an array of page items at run time can I?
Any idea's how I could accomplish this? Is there a better way of doing this?
Also is there a term or a name for what I am doing by creating these 'virtual' columns in another table?
I found this method when looking at Oracles Workflow tables.

Creating Page Items dynamically is not available. You will have to create excess items and hide/show , etc. But you cannot change the Item Type. All in all, too many limitations in this approach.
>

The 100 item limit will hit you if you go with extra item on page. With Tabular Form that should not be a limitation, unless you are exceeding the 50 item limit of APEX_APPLICATION.G_Fnn items, and the 60 column limitation of Report region with "Use Generic Column Names (parse query at runtime only)" of Dynamic region.

Yes, you can do it. Updatable report/ Tabular Form query can be constructed from the Meta Data using PL/SQL Function Returning SQL Query . It will be a bit of coding in PL/SQL where you use the Meta Data and the Meta Data of the Meta Data to piece together your SELECT with the right APEX_ITEMs. It might have a performance penalty associated with it, but will not be a serious degradation.

Giving a new runtime a time to live

Hi
I am making a system which lets a user submit the source code to a program, the system takes the code, compiles it and then tests it.
When i run the submitted program to run some tests on it i would like to give it a time to live, incase there are any errors in it which would mean it would run indefinately (eg never ending loops etc).
At the moment i launch the program with the following code;
String cmd = "./" + testprogram + " " + input + " " + output;
Runtime ra = Runtime.getRuntime();
try{
ra.exec(cmd);
catch(java.io.IOException ew) {
System.out.println(ew);
this is under linux
many thanks for any help i get
Rich

When you call exec(string), a Process is returned. You should be able to use the destroy() method to end it.

More than a year, since the original one was posted, later I came across the same issue. What a pity, BEA wasn't interested in looking into this. I spent a little time to find out that in the javascript the variable methodString contains semicolon separated methods signature has a method
assignGroups(java.lang.String,[Ljava.lang.String;) - REMOTE
with a semicolon embeddeb in it. The signature actually is
assignGroups(java.lang.String,java.lang.String[])
This extra semicolon makes the length (26) of the methods got one more than it suppose to be.

Hi Mark,
Try out the following options.
1) Run /SAPAPO/RTO_ORD_COMP and check any inconsitencies
2) Check all the capacities (primary and secondary if any) are
maintained in the work centre and recif and try
3) Check the input-output relations in the bom/routing are defined
properly alongwith activity relationship
4) Check SAP note 1147324

Displaying input from Runtime.exec()

Hi there, after all my troubles, I'm finaly able to get all the input from the unix machine using Runtime.exec() and to have it come out pretty quick. My new problem now is that I need to take that input and display it onto a textPane. Anyone who can help me do that? here is the code I have written, along with the method I use called setPaneText():
class StreamGobbler extends Thread
InputStream is;
String type;
StreamGobbler(InputStream is, String type)
this.is = is;
this.type = type;
public void run()
try
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line=null;
while ( (line = br.readLine()) != null)
System.out.println(type + ">" + line);
} catch (Exception ioe)
ioe.printStackTrace();
private void jMenuItem13ActionPerformed(java.awt.event.ActionEvent evt) {
Object source = evt.getSource();
String serverComm;
serverComm = "";
serverComm = pp.getServerComm();
if(source == jMenuItem13)
try
String osName = System.getProperty("os.name");
Runtime rt = Runtime.getRuntime();
Process commandReturn = rt.exec(serverComm + " /usr/local/bin/dlgexec pd_rm_cm trashcan");
//StreamGobbler errorGobbler = new
//StreamGobbler(commandReturn.getErrorStream(), "ERROR");
StreamGobbler outputGobbler = new
StreamGobbler(commandReturn.getInputStream(), "OUTPUT");
//errorGobbler.start();
outputGobbler.start();
int exitVal = commandReturn.waitFor();
System.out.println("exitVal = " + exitVal);
if(exitVal == 0)
System.out.println("inside the trashcan if");
int cnt = 0;
String outText []= new String [10000];
BufferedReader buffy = new BufferedReader(new InputStreamReader(outputGobbler.is));
while((outText[cnt]=buffy.readLine()) != null)
cnt++;
if(cnt == 9000)
break;
TextAreaPanel tp;
tp = new TextAreaPanel();
for(int cnt2 = 0; cnt2 < cnt; cnt2++)
String temp;
temp = outText[cnt2] + "\n";
tp.setPaneText(temp);
jPanel1.removeAll();
jPanel1.add(tp, BorderLayout.CENTER);
jPanel1.validate();
this.repaint();
catch(Throwable t)
t.printStackTrace();
and here is the method that I call
public void setPaneText(String message)
jTextArea1.setEnabled(true);
//jTextArea1.setEditable(false);
String outText = message;
jTextArea1.setText(message);
jScrollPane1.setViewportView(jTextArea1);
//return outText;

Create Dynamic Structure at Runtime via ALV-Methods!

Hi Experts,
i try to create at the ABAP Runtime a new Structure.
FOR EXAMPLE: I have a internal Table "database" and i dont know their Structure or Typ.
MY Question: How can i get the structuretype for this internal Table "database" ??
                                I thought that it is possible with ALV-Methods, but i dont find the right way.
First Step:       I must get the structure of this internal Table.
Second Step: I must create a workarea/ line of this internal Table, that i can work row for row with the table.
Have someone an code example for me, because iám very confused about this Problem.
With kind regards.
Ersin Tosun

Hello,
For this specific requirement, SAP has provided RTTI class.
Below is a code snippet for your ready reference. In this example we're trying to get the structure of the dynamic table <ITAB> whose structure is not defined till run-time.
TYPE-POOLS: abap.
PARAMETERS: p_table TYPE tabname.
DATA: dref TYPE REF TO data.
FIELD-SYMBOLS <itab> TYPE STANDARD TABLE.
CREATE DATA dref TYPE STANDARD TABLE OF (p_table).
ASSIGN dref->* TO <itab>.
DATA: go_tab_descr TYPE REF TO cl_abap_tabledescr,
      go_struc_descr TYPE REF TO cl_abap_structdescr,
      wa_comp TYPE abap_compdescr.
go_tab_descr ?= cl_abap_tabledescr=>describe_by_data( <itab> ).
CHECK sy-subrc = 0.
go_struc_descr ?= go_tab_descr->get_table_line_type( ).
LOOP AT go_struc_descr->components INTO wa_comp.
WRITE: / wa_comp-name.
ENDLOOP.
I must create a workarea/ line of this internal Table, that i can work row for row with the table.
Sorry i missed the Step 2:
FIELD-SYMBOLS: <itab> TYPE STANDARD TABLE,
               <wa> TYPE ANY,
               <val> TYPE ANY.
LOOP AT <itab> ASSIGNING <wa>.
LOOP AT go_struc_descr->components INTO wa_comp.
*   To access the components of the structure dynamically
    ASSIGN COMPONENT wa_comp-name OF STRUCTURE <wa> TO <val>.
ENDLOOP.
ENDLOOP.

How to get event name in runtime in the method ?

i found that there is a &_WORKITEM.OBJECTTYPE.EVENTS.NAME& element in thw workflow contained. then i do a binding from this element to another element with the same type as &_WORKITEM.OBJECTTYPE.EVENTS.NAME&.
then in the method i use swc_get_element container 'NAME' name.
to get the event name in runtime.
but when i test it in SWUE, it gives error. If i remove this statement, it is oK
ANY advice?

Hello Gang,
_WORKITEM is a workitem object
OBJECTTYPE is its type (WORKINGWI for dialog steps)
EVENTS is a multiline attribute (all events for this type of object: processed, created and deleted in our case /events of WORKINGWI/)
I don't think that is what you need.
You got an error, cause you link a multiline element to a single one.
If you need an access to the TRIGGERING event name, the best is to bind an event name when it is triggered (or e.g. check an event name in the check FM if it is sufficient for your requirement).

Michal

I can't load 11.4. Now I don't have Itunes at all. keeps giving me a runtime error

I keep getting I need to update itunes to the lastest one. I did and after that, I keep getting this error R6034 that says an application has made an attempt to load the c runtime library incorrectly. Please contact support. What do I do? I removed Itunes and tried to download it manually and when I get the finish window, it's over in the left corner with only 1/4 of the end of the message showing. I can't even hit the finish button. What do I do since now my Itunes won't work at all?

Experimental advice ... but, plausibly, the preference files containing the parental control setting may be damaged. If so, removing the iTunes preference files may help.
For the basic technique, see the "Remove iTunes preference files" section from the "User-specific troubleshooting" section of the following document:
iTunes for Windows Vista or Windows 7: Troubleshooting unexpected quits, freezes, or launch issues
To see those folders, you'll need to first set your PC to view hidden files and folders
In your Start menu, open Computer.
In your Organise menu, select Folder Options.
In the View tab, make sure that "Show hidden files and folders" is selected, and Hide extensions for known file types is unchecked.
Click OK.
Prior to doing the preference file rebuilds: Best to make a note of any custom preferences you have set up for your iTunes. (Rebuilding pref files returns preferences to their defaults ... so you'll likely have to set some of those custom preferences up again from scratch.) Also make a note of any third-party plugins/add-ons you have installed. You may have to reinstall those after the rebuilds.
Things to watch out for during the rebuilds
Rebuilding the preference files in the \Local\ location causes the iTunes license agreement to run. So you'll need to agree to that again.
Rebuilding the preference files in the \Roaming\ location causes the iTunes Setup Assistant to run. When prompted to do so, do not add files to your iTunes library. (Otherwise you'll end up with a library full of duplicates.)

I use IncrediMail and it keeps crashing and giving me a Runtime Error what can I do about this?

The message is as follows:
X Runtime Error!
Program:c\Program Files (x86\Incred.Mail\Bin\ImApp.exe
This application has requested the Runtime to terminte it in an unusual way.
Please contact the application's support team for more information.
