Doubt in processing of statements after calling JFrame class
I have two java classes.
The first one is Normal class and the second one is a JFrame class.
In the first Class, i created an object for second JFrame class followed by a set of statements.
Based on the input from the second class, i must process the statements, the problem i am facing is after creating the object for second frame class , the first class continues execution of the remaining statements. I must stop the execution of the statements until i get an input from the second class.
How can i make the first class wait for an input from the second class.
if possible provide me some source code.
Thanks for your help!.
Use a modal JDialog instead of a JFrame.

Call remains in "conferenced" state after the call is released
We have a scenario where a lengthy recorded message is set up through a ICM call routing script. If we call the number we assigned to the script using our hard phones the call is disconnected as soon as the recorded message is finished playing.
When we use Cisco Administrator Desktop and the conference feature, the call remains in the "conferenced" state after the call has been released.
My assumption was that our reports would be smarter than CAD and would get it right. However, reporting agrees with CAD, it thinks the call remained on a conference call for the whole time.
In the script we set some variables for the call, play the message through "RunExtScript" node, set a call type, than use the "ReleaseCall" node to disconnect the call. Any ideas how we can configure the script other than this?Hi,
can you tell us more - do you have Translation Routing set up, perhaps?
Also, can you take a look at the Router Log (on the Distributor server).
And please swith the script to Monitoring mode to see where it fails.

I found several charges on my bank account from Apple on App that is completely free. After calling the number showing on my bank statement there an automated answering that tells you to go to apple website!!! There is nobody to talk to!! Complete rip OFF
And now because I want to communicate with apple support I have to go through the hectic website and community support, this is ridiculous.
I have 5 iPhones in my account and this makes me reconsider upgrading to iPhones again.
Why Apple put a phone number in the bank transaction, if there is nobody to talk to!!!!!!
I hope someone from Apple support can answer my question.Go to getsupport.apple.com. Or, call 1-800-MYAPPLE.
Just because an app is free to download doesn't mean that there aren't in-app purchases available.
Go to iTunes on your computer, log into the iTunes Store with your Apple ID & password, and check your purchase history. Be advised that all iTunes & App Store purchases are final. -
Page item value set in app process not maintained after page submit
Hi -- I have a sequence of events that goes like this:
1) Page 0 region REG_1 is rendered before footer
- Region REG_1 uses javascript / AJAX to call App process PROC_1
- PROC_1 sets Page1 item PAGE1_MESSAGE to X
- After PROC_1 executes successfully, REG_1 does doSubmit()
2) Page 0 region REG_2 is rendered before footer; this happens
after the page submit done by REG_1. (Conditions ensure that
REG_1 is not rendered again)
- Region REG_2 displays PAGE1_MESSAGE (=X) in an alert.
- Region REG_2 uses javascript / AJAX to call App process PROC_2
- PROC_2 sets Page1 item PAGE1_MESSAGE to Y
- PROC_2 sets Application item DEBUG to PAGE1_MESSAGE (this is for debugging)
- PROC_2 sets Application item APP_MESSAGE to Y (this is also for debugging)
- After PROC_2 executes successfully, REG_2 does doSubmit()
3) After REG_2 submits the page, here's what I have:
- Application item APP_MESSAGE = Y. Good. This is what it was set to in PROC_2.
- Page 1 item PAGE1_MESSAGE = X. Bad. This is what it was set to in PROC_1.
- Application item DEBUG = Y. Good. This at least shows that PAGE1_MESSAGE was
set to Y within PROC_2... but for some reason that value is not being preserved
after the app process is done executing.
- There are several other application items set in PROC_2, and they're all correct.
Any ideas as to why this is happening? It seems like this should be
pretty straightforward: set the value, submit the page, the value should be what
I set it to.
Thanks,
CarolHi -- Thanks for the suggestions. First and 3rd (default value, or being overwritten by process or computation) aren't happening. The source for PAGE1_MESSAGE having is Always, Using app item PAGE1_MESSAGE... but I don't see what else could work here. Not sure if that's the problem.
I've put an example on apex.oracle.com. Workspace is dew_mir_tor. Username is [email protected]. Password is Mir97Dew77!Tor. Application is 22679, RefreshAllTest.
To reiterate the description in my original posting, but using the real application item/region/process names:
0) Press Button REFRESH_ALL on Page 1. This branches back to Page 1.
1) Page 0 region Refresh_All is rendered before footer
- Region sends up an alert to show you it's working
- Region Refresh_All uses javascript / AJAX to call App process REFRESH_CZAR (You'll see a "wait" window flash up briefly while the app process is running)
- REFRESH_CZAR sets Page1 item P1_MESSAGE_1 to X (The text here indicates where
the value is being set and when it should be displayed)
- After REFRESH_CZAR executes successfully, region Refresh_All does doSubmit()
2) Page 0 region Refresh_Non_Czar is rendered before footer; this happens
after the page submit done by Refresh_Czar. (Conditions ensure that
Refresh_Czar is not rendered again)
- Region sends up an alert to show you it's working
- Region Refresh_Non_Czar displays P1_MESSAGE_1 in an alert.
- Region Refresh_Non_Czar uses javascript / AJAX to call App process REFRESH_NON_CZAR (You'll see a "wait" window flash up briefly while the app process is running)
- REFRESH_NON_CZAR sets Page1 item P1_MESSAGE_1 to Y (The text here indicates where
the value is being set and when it should be displayed
- REFRESH_NON_CZAR sets Application item TEST_VALUE2 to P1_MESSAGE_1 (this just shows that P1_MESSAGE_1 was indeed set to Y in this process...)
- After process REFRESH_NON_CZAR executes successfully, region Refresh_Non_Czar does doSubmit()
3) After Refresh_Non_Czar submits the page, Page 0 region Display_Messages is rendered.
It sends up an alert so you can see it's working, and then it displays the value in P1_MESSAGE_1.
The value is still the one that was set in REFRESH_CZAR, not the one set in REFRESH_NON_CZAR.
Note that Display_Messages sets P1_MESSAGE_1 back to null, so you won't see it in session state after it's displayed in the alert. But you can see that TEST_VALUE2 is set to the message from REFRESH_NON_CZAR.
Hope this helps solve the problem!
Thanks,
Carol -

Actually my application takes some time to be start service so that the very first user need to wait for some time.
I am facing the exception of not founding initial context is thrown because the load-on-startup and
by creating startup class the classes are loaded before the server comes in to running state.
In that case the server doen't have its host name and port configurated.
At the time of application setup we need to get the initial context from t3: by using
host and port. At this stage any of the process is unable to get the context.
Is there any way by which we can automatically call a class after starting the server.I have deployed a ear file.
which has one Ear project and one ejb module and one portal application and about 4 web applications.
One of my webapplication need to be started before the user start working on any web application.
I have tried to configure and run you suggestion but i am unable to find the place where should i put the listener and startup class entry. my ear project has weblogic-application.xml file i shall put these entry there then xml doesn't validate and i shall get the project compile error. and same case with the application.xml of ear project and portal application weblogic.xml and web.xml file. I have found only one which is not giving compile time error is wlw-config.xml in portal application.
I am working on weblogic workshop 10.2
if you have any idea about that where i can put these configuration entry so that the class will called on firing event by server. then please let me know.
thanks in advance. -
After call commit sql , data can not flush to disk
I use berkey db which support sql . It's version is db-5.1.19.
1, Open a database.
2. Create a table.
3. exec "begin;" sql
4. exec sql which is insert record into table
5. exec "commit;" sql
6. copy database file (SourceDB_912_1.db and SourceDB_912_1.db-journal) to Local Disk of D, then use a tool of dbsql to open the database.
7. use select sql to check data, there is no record in table.

sqlite3 * m_pDB;
int nRet = sqlite3_open_v2(strDBName.c_str(), & m_pDB,SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE,NULL);
2
string strSQL="CREATE TABLE [TBLClientAccount] ( [ClientId] CHAR (36), [AccountId] CHAR (36) );";
char * errors;
nRet = sqlite3_exec(m_pDB, strSQL.c_str(), NULL, NULL, &errors);
3
nRet = sqlite3_exec(m_pDB, "begin;", NULL, NULL, &errors);
4
nRet = sqlite3_exec(m_pDB, "INSERT INTO TBLClientAccount (ClientId,AccountId) VALUES('dd','ddd'); ", NULL, NULL, &errors);
5
nRet = sqlite3_exec(m_pDB, "commit;", NULL, NULL, &errors);
Edited by: 887973 on Sep 27, 2011 11:15 PMHi,
Here is a simple test case program I used based on your description:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "sqlite3.h"
int error_handler(sqlite3*);
int main()
sqlite3 *m_pDB;
const char *strDBName = "C:/SRs/OTN Core 2290838 - after call commit sql , data can not flush to disk/SourceDB_912_1.db";
char * errors;
sqlite3_open_v2(strDBName, &m_pDB, SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE, NULL);
error_handler(m_pDB);
sqlite3_exec(m_pDB, "CREATE TABLE [TBLClientAccount] ( [ClientId] CHAR (36), [AccountId] CHAR (36) );", NULL, NULL, &errors);
error_handler(m_pDB);
sqlite3_exec(m_pDB, "begin;", NULL, NULL, &errors);
error_handler(m_pDB);
sqlite3_exec(m_pDB, "INSERT INTO TBLClientAccount (ClientId,AccountId) VALUES('dd','ddd'); ", NULL, NULL, &errors);
error_handler(m_pDB);
sqlite3_exec(m_pDB, "commit;", NULL, NULL, &errors);
error_handler(m_pDB);
//sqlite3_close(m_pDB);
//error_handler(m_pDB);
int error_handler(sqlite3 *db)
int err_code = sqlite3_errcode(db);
switch(err_code) {
case SQLITE_OK:
case SQLITE_DONE:
case SQLITE_ROW:
break;
default:
fprintf(stderr, "ERROR: %s. ERRCODE: %d.\n", sqlite3_errmsg(db), err_code);
exit(err_code);
return err_code;
}Than I copied the SourceDB_912_1.db database and the SourceDB_912_1.db-journal directory containing the environment files (region files, log files) to D:\, opened the database using the "dbsql" command line tool, and queried the table; the data is there:
D:\bdbsql-dir>ls -al

dbsql> .tables
TBLClientAccount
dbsql> .schema TBLClientAccount
CREATE TABLE [TBLClientAccount] ( [ClientId] CHAR (36), [AccountId] CHAR (36) );
dbsql> select * from TBLClientAccount;
dd|dddI do not see where the issue is. The data can be successfully retrieved, it is present in the database.
Could you try putting in the sqlite3_close() call and see if you still get the error?
Did you remove the __db.* files from the SourceDB_912_1.db-journal directory?
Did you use PRAGMA synchronous, and if so, what is the value you set?
If this is still an issue for you, please describe in more detail the exact steps needed to get this reproduced and provide a simple stand-alone test case program that reproduces it.

Trigger a process chain(PC) after successfull completion of two other PCs
Hi All,
My requirement is to trigger a Process Chain only after successfull completion of two other process chain which are already scheduled to run at different times.
Please tell me how to achieve this into SAP-BW 3.5
Thanks
JharnaHi
It is very simple, I'm doing the same.
Insert Remote Process Chain at the end of the actual process chain and call the other process chain, here you need to give source , destination and process chain name in Remote process chain.
try it, it will work.
Thanks

}The C and C++ standards say that the only thing you can rely on doing in a signal handler is to read and write global volatile variables, abort the program, or call the signal function.
The Unix standard, which applies to Solaris, is more lenient. By default, a signal handler is run on the process stack, although it is possible to specify that a given signal runs on a different stack. If the stack actually used has enough space, you can call functions.
But the Unix standard limits the system functions that you can call. You can call only those system functions that the man page says they reentrant and safe to call from a signal handler. Any function that calls malloc or free is generally not safe, and I/O routines often involve calls to malloc or free. -
Doubt in control break statement
Hi All,
Is there any way to trigger control break statements at new & at end of for non primary key fields.
i want to trigger both control break statements for my requirement , not at change of, because i want to trigger at end of also. Please let me know if any possibility. Thanks
regards
vishalhi vishal,
Variants:
1. AT NEW f.
2. AT END OF f.
3. AT FIRST.
4. AT LAST.
Effect
In a LOOP which processes an internal table, you can use special control structures for control break processing. All these structures begin with AT and end with ENDAT. The sequence of statements which lies between them is then executed if a control break occurs.
You can use these key words for control break processing with internal tables only if a loop is actively processing an internal table and reference is to the innermost currently active loop.
The control level structure with internal tables is static. It corresponds exactly to the sequence of columns in the internal table (from left to right). In this context, the criteria according to which you sort the internal table are unimportant.
At the start of a new control level (i.e. immediately after AT), the following occurs in the output area of the current LOOP statement:
All character type fields (on the right) are filled with "*" after the current control level key.
All other fields (on the right) are set to their initial values after the current control level key.
Between AT and ENDAT, you can use SUM to insert the appropriate control totals in the numeric fields (see also ABAP Number Types) of the LOOP output area (on the right) after the current control level key. Summing is supported both at the beginning of a control level (AT FIRST, AT NEW f) and also the end of a control level (AT END OF f, AT LAST).
At the end of the control level processing (i.e. after ENDAT), the old contents of the LOOP output area are restored.
Notes
When calculating totals, you must ensure that the totals are inserted into the same sub-fields of the LOOP output area as those where the single values otherwise occur. If there is an overflow, processing terminates with a runtime error.
If an internal table is processed only in a restricted form (using the additions FROM, TO and/or WHERE with the LOOP statement), you should not use the control structures for control level processing because the interaction of a restricted LOOP with the AT statement is currenly not properly defined.
With LOOPs on extracts, there are also special control break control structures you can use.
Note
Non-Catchable Exceptions:
SUM_OVERFLOW: Overflow when calculating totals with SUM.
Variant 1
AT NEW f.
Variant 2
AT END OF f.
The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas.See Compatible Work Area with Control Level Processing and Field Symbols Not Allowed as Control Level Criterion.
Effect
f is a sub-field of an internal table processed with LOOP. The sequence of statements which follow it is executed if the sub-field f or a sub-field in the current LOOP line defined (on the left) before fhas a different value than in the preceding (AT NEW) or subsequent (AT END OF) table line.
Example
TYPES: BEGIN OF COMPANIES_TYPE,
NAME(30),
PRODUCT(20),
SALES TYPE I,
END OF COMPANIES_TYPE.
DATA: COMPANIES TYPE STANDARD TABLE OF COMPANIES_TYPE WITH
NON-UNIQUE DEFAULT KEY INITIAL SIZE 20,
WA_COMPANIES TYPE COMPANIES_TYPE.
LOOP AT COMPANIES INTO WA_COMPANIES.
AT NEW NAME.
NEW-PAGE.
WRITE / WA_COMPANIES-NAME.
ENDAT.
WRITE: / WA_COMPANIES-PRODUCT, WA_COMPANIES-SALES.
AT END OF NAME.
SUM.
WRITE: / WA_COMPANIES-NAME, WA_COMPANIES-SALES.
ENDAT.
ENDLOOP.
The AT statements refer to the field COMPANIES-NAME.
Notes
If a control break criterion is not known until runtime, you can use AT NEW (name) or AT END OF (name) to specify it dynamically as the contents of the field name. If name is blank at runtime, the control break criterion is ignored and the sequence of statements is not executed. If name contains an invalid component name, a runtime error occurs.
By defining an offset and/or length, you can further restrict control break criteria - regardless of whether they are specified statically or dynamically.
A field symbol pointing to the LOOP output area can also be used as a dynamic control break criterion. If the field symbol does not point to the LOOP output area, a runtime error occurs.
If you use AT within a LOOP with an explicitly-specified output area, the area must be compatible with the line type of the internal table so that it can be initialized properly (as described above) at the start of a new control level.
You can restrict control break criteria further, regardless of whether they were defined statically or dynamically, by specifying offset and/or length.
Variant 3
AT FIRST.
Variant 4
AT LAST.
Effect
Executes the appropriate sequence of statements once during the first (AT FIRST) or last (AT LAST) loop pass.
Example
TYPES: BEGIN OF COMPANIES_TYPE,
NAME(30),
PRODUCT(20),
SALES TYPE I,
END OF COMPANIES_TYPE.
DATA: COMPANIES TYPE STANDARD TABLE OF COMPANIES_TYPE WITH
NON-UNIQUE DEFAULT KEY INITIAL SIZE 20,
WA_COMPANIES TYPE COMPANIES_TYPE.
LOOP AT COMPANIES INTO WA_COMPANIES.
AT FIRST.
SUM.
WRITE: 'Sum of all SALES:',
55 WA_COMPANIES-SALES.
ENDAT.
WRITE: / WA_COMPANIES-NAME, WA_COMPANIES-PRODUCT,
55 WA_COMPANIES-SALES.
ENDLOOP. -
JNI - core dump - internal error on linux after calling Java method
I'm getting a core dump after calling athe main statric method using JNNI.
On linux.
I can get the class id correcttly but when I attempt to call the method it craches with an internal error , anyone know why it would crash instead of just not work.
if(cls)
main_methodID = env->GetStaticMethodID(cls, "main", "([Ljava/lang/String;)V");
printf("Class Found Successfully\n");
else
printf ( "cls not found\n");
return 0;
if(main_methodID)
jstring first_str = env->NewStringUTF("The First String");//create string
jobjectArray args = (jobjectArray)env->NewObjectArray(1,env->FindClass("java/lang/String"), first_str);//new array with 2 elements
env->SetObjectArrayElement(args, 2, first_str);//insert the second string into index 1 of the array
jstring second_str = env->NewStringUTF("The Second String");//create string
env->SetObjectArrayElement(args, 1, second_str);//insert the second string into index 1 of the array
env->CallStaticVoidMethod(cls, main_methodID, args);//pass the array to the Java main method
The JAVA method is
public static void main(String[] args) {
System.out.println("Main method in Framework");
Framework framework = new Framework();
I see yere points but what I see on linux is it makes it to the constructor of the Java object and somewhere afterwards it bails out, the Java app does work alone. It appears to have problems initializing the JFrame, could there be a problem with the Java inheritance when a JVM is invoked throurgh native invocation??
Here's some of the Java stuff
public class Framework extends WindowAdapter {
public int numWindows = 0;
private Point lastLocation = null;
private int maxX = 500;
private int maxY = 500;
public Framework() {
System.out.println("JAVA Framework cnst");//GETTING HERE
makeNewWindow();
public void makeNewWindow() {
System.out.println("JAVA makeWindow"); //GETTING HERE
JFrame frame = new MyFrame(this); //NOT GETTING HERE!!!!!!!!!
numWindows++;
System.out.println("Number of windows: " + numWindows);
System.out.println("Frame location: " + lastLocation);
frame.setVisible(true);
System.out.println("Post Java set frame visible");
public static void main(String[] args) {
System.out.println("Main method in Framework");

Has anybody experienced camera drivers wont work after calling Camera.getCamera() so many times?
Using Flash Player on Windows machines, since version Flash Player 11.4 - Flash Player 15 (ActiveX version), and every version after that we have experienced an issue in which Hauppauge PCIe cameras and Videology cameras or other non-standard cameras fail to work with Flash Player after calling getCamera() so many times. For example, we get the camera, and publish a netstream for 10 minutes, then we set the camera to null. Later we call the camera again and after doing this 25 times, or 100 times, the camera driver just seems to fail, and Flash Player acts like it is streaming the camera, but the NetStream info indicates that zero bytes of video data was streamed indicating that there were no pixels that came from the camera.
Has anybody else experienced this issue to where you have to restart the browser or the Windows process in order for Flash Player to be able to getCamera() properly again?Yes, it appears that others have experienced a similar issue. Adobe has not yet confirmed that this is a bug, but it is being tracked here:
Bug#3850401 - Handle leak with video.attachCamera leading to inoperable camera -
Retain the entityState and postState of entities even after calling commit
Dear all,
I am using view objects based on programmatic entity objects in my application for which data is populated from an array using populateRow().
I need to update the newly created/updated/deleted rows in this EO into the database using a stored procedure.
The stored procedure needs the input as an array of only those records that are created/updated/deleted with indicators of whether each row in the array is inserted/updated/deleted.
I have exposed a client interface method in the view object Impl class that calls the dbTransaction().commit() first and then calls the stored procedure.
In the doDML(), I am constructing the array and keeping the values in a page flow scope which is then accessed in the voImpl method.
In case if an exception occurs in the business logic inside the stored procedure, the data will not get posted in the database and the exception is displayed to the user in the UI.
After calling the stored procedure, I am clearing the page flow scope irrespective of whether the data has been posted to DB or not.
Consider the scenario,
I have updated 2 records. Of these, I've updated one of the records with wrong values. As per my logic, on calling the save method, doDML() will construct the data array for these two records.
Inside the stored procedure, the wrongly updated row is identified and exception is raised and the data will not get posted in the database.
Now, on getting the exception, I update the worngly updated record with proper value.
On calling the save method again, my doDML() is constucting the array with the currently updated record alone. But actually I need all the records (2 records in this case) that were modified.
My understanding is, since I've called the commit() action, all the records that make my transaction dirty gets updated as status_unmodified subsequently.
Hence, on calling commit the second time, only one record will be in modified state and that record alone is getting constructed in the array.
If I am correct,
1. Is there any way to make all those records with their status as they were before calling the commit.
2. Should I construct my array in some other method instead of doing it in doDML().
Thanks in advance.You may want to try calling setClearCacheOnRollback(false) and rollback instead when you get the exception from the stored procedure. I still haven't understood where the commit is done...
You may want to consider using an Application Module variable to store your list if this helps.
Cheers,
Nick -
Calling JFrame's pack() freezing my apps
Hi all,
When calling JFrame's pack() method my apps suddenly do not respond, I've tried to uninstall and reinstall the JDK but the problem persists. I use J2SDK 1.4.1_04. What's the problem ?
Any help would be greatly appreciated.
SetyaThanks for the response,
My OS is Windows 2000 Advanced Server SP3, previously I've tried 1.3.1 & 1.4.0 which run fine, I've just downloaded the 1.4.1_04 and gave it a try. Actually my app does not completely freeze only the JFrame won't show up and no messages at all. This happens all of sudden after running fine for a couple of days.
This also happens to the demo apps accompanying the JDK.
Should I try 1.4.2 ? Because I don't want my PC stuffed with JDK I don't use. The reason why I can not keep up with the JDK release is because I have very limited access to internet so I can not download it as I want.
Setya -
how can i know if the sync process is done after a bookmark adding or so such and when it is processing , immediately after changes or what?
I don't know whether you solve your problem or not! Anyway, I have the same problem. The program hangs when getInputStream is called.
DataInputStream dis = new DataInputStream(request.getInputStream());
If you have the answer, please let me know. Thanks!!
