Runtime.exec() - Problem when using cvs-command

I have a problem with the Runtime.getRuntime().exec() - Command. I try to execute a command to export files from our cvs-repository. As you hopefully know, cvs produces a lot of output.
When I start my 'cvs export ... '- command from the console-window of windows, everything works perfect. But when I try to use the Runtime.getRuntime().exec("CVS export ...") the created cvs-subprocess stops after the export of the first three files. When I close the main-window, where the cvs-process was started from, the cvs-process continues working.
I could see, that many others had the same problem, but I couldn't find a real solution there.
Is there a possibility to clear/delete the output-buffer of the cvs-subprocess, because I don't really need the information, that cvs gives me. It is enough for me when cvs stores the files :-)
My source:
public void executableTest()
Runtime run = Runtime.getRuntime();
try
Process cvsProcess = run.exec("cvs export .... ");
cvsProcess.waitFor();
BufferedReader in = new BufferedReader
          ( new InputStreamReader(cvsProcess.getInputStream()) );
     String line;
     while ((line = in.readLine()) != null)
          System.out.println(line);
     catch (Exception e)
     System.out.println(e.getMessage());
Thanks for your help.

if the buffer is overflowing, then you don't want to do the waitfor until after you've hit the end of the inputstream, me thinks.

Runtime exec problem with command "start"

L.S,
I'm working on a webservice client for uploading
and downloading files. When a file is downloaded, it
should be opened by the appropriate application. I
know that this is -in theory- possible by issuing a
start command through Runtime.getRuntime.exec():
public void doSomething(String realName, DataHandler handler) {
File outFile = new File(realName);
FileOutputStream out = new FileOutputStream(outFile);
handler.writeTo(out);
out.close();
String fileName = outFile.getAbsolutePath();
Process p = Runtime.getRuntime().exec("start " + fileName);
}Running this on my Win2000 system with J2RE 1.4.2 consistently
fails with this message:
java.io.IOException: CreateProcess: start C:\tmp\test.pdf error=2When I issue the exact same command from a DOS shell, Adobe
starts up with the test document loaded. I now believe that my own
application is somehow 'holding on to' the file, preventing an
external application like Adobe from consuming the same file.
Does anyone know how I can get around a problem like this? How do
I start the appropriate application and feed it the file that was
just downloaded by the user?

I did a search for Runtime.exec and found some good help in this forum. Someone posted something like the following and it works pretty well.
<<begin code>
// Determine proper shell command (extend per OS)
String os_name = System.getProperty("os.name");
String shellParam "";
if (os_name.startsWith("Windows"))
if ( (System.getProperty("os.name").endsWith("NT")) ||
(System.getProperty("os.name").endsWith("2000")) ||
(System.getProperty("os.name").endsWith("XP")) )
shell = "cmd.exe";
} else
shell = "command.com";
shellParam = "/C";
// Create a string with your program executable
String command = "myprogram.exe";
// Create an array of each command, I found that placing "cmd.exe /c"
// in the same string doesn't work.
String[] cmd_array = new String[] {
shell,
shellParam,
command
Runtime.getRuntime().exec( cmd_array );
<<end code>>
Do a java API search for Runtime.exec (if you use Eclipse right click and hit Open Declaration) there are ways to invoke exec that support setting of the environment as well as the current directory.

Runtime.exec does not work for commands with lengthy outputs

I need to use Runtime.exec to run some custom commands on a Unix box. I have been doing this for quite some time now and had begun to feel comfortable when recently I started facing a problem. The thing is, whenever there is a command which prints a lot of data on to the console, the program is not able to exit from the waitFor method. Is there some thing that can be done about this?
Following is a part of the code I use:
Runtime rt = Runtime.getRuntime();
Process p = rt.exec (command);
System.out.println ("Got the process");
int exitValue = p.waitFor();
System.out.println ("Exit value: " + exitValue);When the output of the "command" is lengthy, it hangs after printing "Got the process".
PS: By lengthy output, I mean that the command results in printing lines to the console which might be more than 100 in number. Say, something like what "ls -R /" would do in Unix / Linux.

From java.lang.Process API doc:
The Runtime.exec methods may not work well for special processes on certain native platforms, such as native windowing processes, daemon processes, Win16/DOS processes on Microsoft Windows, or shell scripts. The created subprocess does not have its own terminal or console. All its standard io (i.e. stdin, stdout, stderr) operations will be redirected to the parent process through three streams (Process.getOutputStream(), Process.getInputStream(), Process.getErrorStream()). The parent process uses these streams to feed input to and get output from the subprocess. Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, and even deadlock.
So you need to consume the process' output. Check the StreamGobbler example from this article.
Hope it helps.

Exchange 2013 CU5 , Exchange Power Shell very very very slow reasponse when using get command.

Exchange 2013 CU5 , Exchange Power Shell very very very slow reasponse when using get command.
First my organize has Exchange on 2 site like
site A (internet facing) : 2CAS 2 MB all are Services pack1
site B (DR Site , no user active on this site) : 2CAS 2MB all are Services pack 1
so today I upgrade Exchange 2013 from SP1 to CU5 start on "site B" and I found this issue and the details is....
When I open EMS on any CU5 for query something (like get-mailboxdatabasecopystatus) the response return very slow and some query will not return at all (like get-owavirtualdirectory).
But If I using EMS on SP1. Everything is ok then I try to use EMS on SP1 connect to CU5 and try to query something. the result is
some query command cannot return for any result that are server on siteB (just some query command)
Problem
EMS on CU5 return very slow result.
EMS on SP1 still ok.
Does anyone face this problem before for CU5??? Please help me figure this out. Thank you
reply from Social.technet

Hi,
Have you used the above cmdlets to check your Exchange server health?
"all other command that I ran on EMS didn't logged on event viewer.", my environment is the same with you. I use Exchange 2013, only errors will be displayed in MSExchange Management. Actually, it is not related to slow EMS response.
Hope it helps.

Problem when using About Operator in Contains Query

Hi,
I'm new to Oracle and this forums too. I have a problem when using about operator in contains query.
I create a table with some records and then create a context index on 'name' column.
CREATE TABLE my_items (
id           NUMBER(10)      NOT NULL,
name         VARCHAR2(200)   NOT NULL,
description VARCHAR2(4000) NOT NULL,
price        NUMBER(7,2)     NOT NULL
ALTER TABLE my_items ADD (
CONSTRAINT my_items_pk PRIMARY KEY (id)
CREATE SEQUENCE my_items_seq;
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Car', 'Car description', 1);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Train', 'Train description', 2);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Japan', 'Japan description', 3);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'China', 'China description', 4);
COMMIT;
EXEC ctx_ddl.create_preference('english_lexer','basic_lexer');
EXEC ctx_ddl.set_attribute('english_lexer','index_themes','yes');
EXEC ctx_ddl.set_attribute('english_lexer','theme_language','english');
CREATE INDEX my_items_name_idx ON my_items(name) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS('lexer english_lexer');
EXEC ctx_ddl.sync_index('my_items_name_idx');Then I perform contains query to retrieve record :
SELECT count(*) FROM my_items WHERE contains(name, 'Japan', 1) > 0;
COUNT(*)
      1
SELECT count(*) FROM my_items WHERE contains(name, 'about(Japan)', 1) > 0;
COUNT(*)
      1But the problem is when I using ABOUT operator like in Oracle's English Knowledge Base Category Hierarchy it return 0
SELECT count(*) FROM my_items WHERE contains(name, 'about(Asia)', 1) > 0;
COUNT(*)
      0
SELECT count(*) FROM my_items WHERE contains(name, 'about(transportation)', 1) > 0;
COUNT(*)
      0I can't figure out what 's wrong in my query or in my index.
Any help will be appreciated.

Hello (and welcome),
You'd be best asking this question in the Oracle Text forum, here:

And by the way, it will help others to analyse if you put {noformat}{noformat} (lowercase code in curly brackets) before and after your code snippets.
Good luck!

ORA-01403: no data found Problem when using AUTOMATIC ROW FETCH to populate

ORA-01403: no data found Problem when using AUTOMATIC ROW FETCH to populate a form.
1) Created a FORM on EMP using the wizards. This creates an AUTOMATIC ROW FETCH
TABLE NAME - EMP
Item Containing PRIMARY KEY - P2099_EMPNO
Primary key column - EMPNO
By default the automatic fetch has a ‘Process Error Message’ of ‘Unable to fetch row.’
2) Created a HTML region. Within this region add
text item P2099_FIND_EMPNO
Button GET_EMP to submit
Branch Modified the conditional branch created during button creation to set P2099_EMPNO with &P2099_FIND_EMPNO.
If I then run the page, enter an existing employee number into P2099_EMPNO and press the GET_EMP button the form is populated correctly. But if I enter an employee that does not exist then I get the oracle error ORA-01403: no data found and no form displayed but a message at the top of the page ‘Action Processed’.I was expecting a blank form to be displayed with the message ‘Unable to fetch row.’
I can work around this by making the automated fetch conditional so that it checks the row exists first. Modify the Fetch row from EMP automated fetch so that it is conditional
EXIST (SQL query returns at least one row)
select 'x'
from EMP
where EMPNO = :P2099_EMPNO
But this means that when the employee exists I must be fetching from the DB twice, once for the condition and then again for the actual row fetch.
Rather than the above work around is there something I can change so I don’t get the Oracle error? I’m now wondering if the automatic row fetch is only supposed to be used when linking a report to a form and that I should be writing the fetch process manually. The reason I haven’t at the moment is I’m trying to stick with the automatic wizard generation as much as I can.
Any ideas?
Thanks Pete

Hi Mike,
I've tried doing that but it doesn't seem to make any difference. If I turn debug on it shows below.
0.05: Computation point: AFTER_HEADER
0.05: Processing point: AFTER_HEADER
0.05: ...Process "Fetch Row from EMP": DML_FETCH_ROW (AFTER_HEADER) F|#OWNER#:EMP:P2099_EMPNO:EMPNO
0.05: Show ERROR page...
0.05: Performing rollback...
0.05: Processing point: AFTER_ERROR_HEADER
I don't really wan't the error page, either nothing with the form not being populated or a message at the top of the page.
Thanks Pete

Coercion problem when using Shared Variable

I have a curious coercion problem when using Shared Variables. I want to share the state of a State Machine, which is an enum saved as a control (typedef) called TYPE State (see attached). I create a shared variable called State and define it as a Custom Control, using the just-mentioned typedef. So far, so good. I've attached three simple VIs -- the first one, Init State, simply wires a constant to the input of the Shared Variable to initialize it -- the wired constant is, of course, defined by the typedef. However, the Get State and Set State, meant to wire an indicator (for reading the state) or control (for setting it), develop coercion dots when wired into the Shared Variable. Why? How do I get rid of the dot? [I suppose I could abandon my typedef and custom control, but the beauty of typedefs and custom controls is that it "enforces" rules, lets you use enums for clarity, keeps the code "honest", etc. -- I'd hate to give that up just to get rid of a dot!].
On a related note, the code seems to work. This is much too simplistic to do anything, but if you open Set State and Get State, set the state to anything, run it (it immediately stops, of course), then run Get State, you'll see the chosen state appear in the indicator. So it does appear to work. The "error" (coercion dot) may, I suppose, be a "bug" in Labview because it can't figure out the mapping of the (very simple!) Custom Control, but if so, I hope it gets fixed quickly!

Hello Bob,
I am also seeing this behavior, I will escalate this question to our LabVIEW developers and post again here no later than next Tuesday, November 27th as National Instruments will be closed for the remainder of this week.
If this issue does turn into a product suggestion, I would suspect the workaround would to live with the coersion dot for the time being.
Enjoy the holiday

NLS support problems when using AL32UTF8 in dads.conf

Hello,
Following a post by Joel Kallman, in one of the forum threads, about the mandatory use of AL32UTF8 in dads.conf, when running HTML DB v2.0, I changed my PlsqlNLSLanguage parameter accordingly.
Prior to the change, I experienced some problems when using non-English characters some application items appeared as gibberish when contained non-English characters, and the LIKE operator didn't perform as expected. After the change, it all seems to work OK, but now I have a different problem.
All the non-English characters in my HTML page source code appears as gibberish. On screen, at run time, everything display correctly, but the source code seems to be corrupted. It is very difficult, and very annoying to debug the pages that way. Is there a way to enjoy both worlds Using AL32UTF8 in the dads.conf, as required, and still getting a coherent HTML source code, containing non-English characters?
Thanks,
Arie.

TS2570 doesn't work, still the same problem when using Rapidweaver software. NOT with other software.

i tried everything in this article, but still have the same problem when using Rapidweaver software. NOT with other software. I am converting my iWeb site to Rapidweaver, whenever there is a calmer period in my office. I have 16 Gb RAM on my NEW iMac and have Parallels desktop, mail, safari, iWeb and Rapidweaver running simultanious.
I never have the problem if i don't use Rapidweaver, but after i have added several pages to Rapidweaver, the problem begins. my iMac won't start up. the only thing that works is re-installing Macos OS X 10.8. i tried even whiping the completeharddrive, and reinstalling with a complete new user, the same problem.
I had it on my previous iMac also, and bought a new one because i thought the problem was in the iMac first. i hadn't noticed it only happens with using rapidweaver.
i sent my complete rapidweaver project to the programmers from rapidweaver at Realmacsoftware, but they couldnt reproduce my problem, there macs started up without any problem.
i deleted all the rapidweaver addons and extra stacks, and started a complete new project.
saterday i had the problem again, after adding about 5 new pages to my rapidweaver site.
i think i have reinstalled Macos OS X 10.8.2 20 or 30 times by now
does anyone have a sollution?

Type '''about:support''' in the URL bar and hit Enter.
Scroll down almost to the bottom of that listing and see if you have '''user.js Preferences''' just above the '''''Graphics''''' category.
If you do have that, click on '''user.js file''' in this sentence. 
''Your profile folder contains a user.js file, which includes preferences that were not created by Firefox.''
Does that "different homepage" appear in that user.js file?

Performance problem when using CAPS LOCK piano input

Dear reader,
I'm very new to Logic and am running into a performance problem when using the CAPS LOCK-piano-keyboard for input of an instrument: when I'm not recording everything is fine and the program instantly responds on my keystrokes, but as soon as I go into record-mode there is sometimes a delay in the response-time (so I press a key and it takes up to half a second longer before the note is actually played).
Is there anything to do about this to improve performance (for example turning of certain features of the application), or should I never use the CAPS LOCK keyboard anyway and go straight for an external MIDI-keyboard?
Thanks and regards,
Tim Metz

Does your project have Audio tracks and just how heavy it is, how many tracks? Also, what kind of Software Instrument do you use?

Problem when using Javabeans in ADF?

Hi,
I encountered a problem when using ADF.
Please look at the following 2 classes :
public class Person
private String name;
private String city;
private int age;
public Person(String name, int age, String city)
this.name = name;
this.age = age;
this.city = city;
public Person()
public void setName(String name)
this.name = name;
public String getName()
return name;
public void setAge(int age)
this.age = age;
public int getAge()
return age;
public void setCity(String city)
this.city = city;
public String getCity()
return city;
public class PersonFactory
public PersonFactory()
public List getPersons()
List list = new ArrayList();
list.add(new Person("peit", 18, "dalian"));
list.add(new Person("robin", 22, "shenyang"));
list.add(new Person("Joe", 30, "York"));
list.add(new Person("Edi", 23, "Beijing"));
return list;
public List getNames()
List list = new ArrayList();
list.add("Peit");
list.add("Robin");
list.add("Joe");
list.add("Edi");
return list;
public void commit()
System.out.println("Data commited");
I created the PersonFactory class as DataControl, so I can use the getPersons() and getNames()(just for test, so they are simple), I drag the names from
the DataControl palette as Table in a JClientPanel, good luck, it works and displays the 4 Strings in a table, but when I drag the persons from
the DataControl palette as Table in the same JClientPanel, it does not work and raises exception :

Hi, Frank
Thank you for your reply.
I am sorry for not explaining well. I mean that the getNames() works fine, but getPersons() does not. The only diferenece between them is the former is simple string and the latter is javabean, but when I made the PersonFactory as DataControl, I set the bean class Person for the getPersons()(list of persons) bean class.
I debuged the class, the exceptions raised when the table for getPersons() setModel() method called.
So, where is the problem?
Thanks.
