Hwo to put and get data to a mq queue through java

Hi All
I would like to know how to put and get messages into a mq series server which is residing on another machine through a java program.
I do not have a mq client installed in my machine..
I have WSAD in my machine.... Should i definitely use a JMS for the same?
PR.

The MQ client installation is free. You can download it from ibm.com, install it, and refer to the application development documentation that accompanies the installation. I believe there are even sample java programs included in the installation.

FTP put and get

When using FTP put and get to transfer files, the program does not go into passive mode. My website requires the following sequence of commands: TYPE A, PORT, PASV, RETR or STOR filename.
Please update Windows FTP for XP & Windows 7 and later or provide me with the means of using raw FTP commands in my programs.

Hello ray.crwfrd,
Please explain a bit about the requirement in case of misunderstanding.
What do you mean about the sentence ‘update Windows FTP for XP & Windows 7’?
The following article is about the means of raw FTP command.

Sending and getting data from external file.

I'm running it in actionscript 1 and 2 since 3 wouldn't work when getting data from external media. I'm trying to find out how to post data to a PHP file and getting from that file I'm trying to make the flash for something that works like a game but differently. Since I just found out how to make the HTML stuff show up but a lot of times, some of my text will not appear so I don't know what's going on.
Does anyone know how to send and get data both at the same time from a sample file?
The sample file is example.php
It has to sent information like ID and NAME
and it has to get information like Description and userID

The tutorial I pointed you to does provide the visuals you requested, both the AS code and sample PHP code, so I can't see where your learning by visuals aspect holds up.... your approach sounds more like you want someone to hand you a tailored solution that you won't need to learn from. Visuals require reading and doing. If that fails to get absorbed or you couldn't understand/revise it, what could anyone else prepare for you that would work better?
I did the tutorial and everything but every time I press the button or even load it, it keeps on saying undefined. I like the have a sample FLA file so I can figure things out. I did everything from the site but it won't work out for me.
I did step 5 too because it was almost all that I was looking for but it won't even work. keeps on saying undefined. I would show you but webcam max won't work and I can't show you an example.
EDIT:
You know it's frustrating when I don't know how the heck I'm supposed to do this stuff. I read the whole dang thing and I still can't get this dang thing working.
I did everything. EVERYTHING. I just don't get this crap.

Read and Get Data from PDF

Hi All,
I am fairly new to programming macros in Excel VBA, and right now I need to write a macro that can open a PDF file and read it and get data from there and paste it into an excel spread sheet. Is this possible? If so can you give me some sample code
that would do that?

I did this once many years ago. I had to have Acrobat Professional installed ($$$). There are free pdf parsers that you access from VBA using Win32 commands like:
https://code.google.com/p/peepdf/
Maybe something has changed since I did it

I've just upgraded to iPhone 4S and restored data from my old iPhone through iTunes. I'm being asked for a password to get into my phone and the old password I had doesn't work. I don't know what password it's looking for

I've just upgraded to iPhone 4S and restored data from my old iPhone through iTunes. I'm being asked for a password to get into my phone and the old password I had doesn't work. I don't know what password it's looking for

Thanks for replying, I'm a real techno-cretin. What do you mean by not using the backup? I'm busy trying to restore my new phone and it's doing a 6 hour download with updates. Can I restore the data from my old phone backup onto the new iPhone 4S when the download is done?

PUT and GET Buttons disappeared?

In the file panel the buttons for PUT and GET are not showing upp at all. What can I do?

It sounds as though you set up a site selecting FTP & RDS Server. Select Site > New Site to define the site correctly.

Problem about put and get

hi there,
I met a problem, when i put the data, and get it.
key data
aaa aaaaaa
bbb bbbbbb
ccc cccccc
I have put "aaa", "bbb" and "ccc" into db, but when I try to get the key for "aaa" , "bbb", it return the data "cccccc", how can I solve it?
after that, when i get the key "ddd", "eee" , and all strings are length 3, the key does not in the DB, it also return the data "cccccc". Did I do something wrong on my code?
void Set1(CString sKey)
int ret;
std::string sdb = "test.db";
Db db(NULL, 0);
ret = db.open(NULL,
     sdb.c_str(),
     NULL,
     DB_BTREE,
DB_CREATE,
     0);
std::string skey, sdata;
skey = sKey;
sdata.append(skey);
sdata.append(skey);
Dbt key(&skey, skey.length());
Dbt data(&sdata, sdata.length());
ret = db.put(NULL, &key, &data, 0);
if(ret==0){
TRACE("success\n");
ret = db.close(0);
void Get1(CString sKey)
int ret;
std::string sdb = "test.db";
ret = db.open(NULL,
sdb.c_str(),
     NULL,
     DB_BTREE,
     DB_CREATE,
     0);
Dbc *cur;
ret = db.cursor(NULL, &cur, 0);
std::string skey, s2, a2;
skey = sKey;
Dbt key(&skey, skey.length());
Dbt data;
memset(&data, 0, sizeof(data));
ret = cur->get(&key, &data, DB_SET);
if(ret!=DB_NOTFOUND){
a2 = (std::string*) data.get_data();
s2 = (std::string*) key.get_data();
TRACE("FOUND %s %s\n", s2->c_str(), a2->c_str());
ret = cur->close();
ret = db.close(0);
}

Hi,
The problem seems to be with these lines:
std::string skey, sdata;
Dbt key(&skey, skey.length());
Dbt data(&sdata, sdata.length());You are constructing a Dbt with data that is actually a pointer to a C++ std::string object. You want the value to be an actual c style string.
An alternative would be to construct the Dbts like:
Dbt key(skey.c_str(), skey.length());
Dbt data(sdata.c_str(), sdata.length());You will need to create a new std::string out of any data retrieved from the database as well. Since it will now be just a C-style char * string.
I hope this helps.

!!! Storing and Getting data from HashMap !!!

Hi ,
I have got a doubt if this is possible .. Please let me know if this can be implemented ..
I have a Process1 running which stores data into HashMap one by one from the Users.
Eg:
Key Object
1 ---> Karthik
2 ---> Raaghav
3 ---> Srikanth
and so on ..
Now what i internally do is i will wait for 5 min Duration (Session TimeOut).Once it is Over 5 min I will delete it from HashMap and Store it in a file ..
Iam also using WebServer Eg:Iplanet .
Now when i Shut down Iplanet all the data in the HashMap is Lost .
My Requirement is to write another Process2 which will be invoked as soon as Iplanet is ShutDown and This process has to read the data from HashMap which is not Timed out .And write it into the File ..
Q1)Please Let me know if this is can be Done ..
Task Done :
Process1 is already existing
Doubts :
Q2)If we write a Process2 will it spawn another VM or it will take the same VM that of the Process1.
Becos if it spawns another VM then I will not be able to get the data from HashMap of the Process1..
Thanks in Advance,
[email protected]

Thank You for the ..
But my prblm is that the Process1 is already Existing which reads and writes in to HashMap ( Not a Servlets) ..Its a Pure Java Code ..
And Now the requirement is another Process2 lets say which is put in thread (running in background )which gets the data from the HashMap of the Process1 or in other words Use the Same HashMap and not a different One ...
Process1 ------------------>HashMap
(write.java) (writes data ) /\
|
|
|(get Data)
|
|
|
Process2
I hope iam clear with my requirement ..
If Any further explanation Required Iam perpared to give ..Please let me know
thanks in advance ..

Possibly using the document() function.

Unexpected results getting data from two fact tables through conformed dim

Hi all,
We are getting an unexpected behaviour in our OBIEE 10.1.3.3.3. We have this scenario:
We have {color:#0000ff}2 fact tables{color}{color:#000000} called F1 and F2. F1 has one measure, f1m1 and F2 has another one, f2m1.
We have {color:#0000ff}4 conformed dimensions{color}, called D1, D2, D3, Date.
When we are requesting for individual fact tables, we are getting:
date d1 d2 d3 f1m1
dt1 - x - y - z - m1
dt1 - x - y - z' - m2
date d1 d2 d3 f2m1
dt1 - x - y - z - m3
dt1 - x - y - z'' - m4
But, trying to obtain a compare scenario, we are getting
date d1 d2 d3 f1m1 f2m1
dt1 x y z m1 m4
Instead of
date d1 d2 d3 f1m1 f2m1
dt1 x y z m1 m3
Looking at query log, we have catched the reason. That's why BI Server is using to solve this request using ROW_COUNT() to join SAWITH0 and SAWITH1 in SAWITH2 result set. So, the order may not be the same in the results sets in every fact table. More or less, generated query is like:
WITH
SAWITH0 AS
(select ....
from F1),
SAWITH1 AS
(select ...
from F2),
SAWITH2 AS
select from (select ...
ROW_NUMBER() OVER PARTITION (....) c10
from SAWITH0.d1 full outer join SAWITH1.d1 ....) D1
{color:#ff0000}where (D1.c10 = 1){color}
select SAWITH2. ....
from SAWITH2
order by c1..c10
The problems seems to be that BI server is ordering the result sets SAWITH0 and SAWITH1 and getting row number to join this results sets, but this is not getting the correct result.
Any ideas?
TIA

I have done a logical fact table with two fact table source on it.
The Sql performed against the database was this one.
-------------------- Sending query to database named PRODS_AIX (id: <<153418>>):
WITH
SAWITH0 AS (select sum(T21296.CONSUMERS_SALES_EURO) as c1,
     T21309.DIVISION_CODE as c2
from
     DIVISION T21309,
     C_CONSUMERS_SALES T21296
where ( T21296.DIVISION = T21309.DIMENSION_KEY )
group by T21309.DIVISION_CODE),
SAWITH1 AS (select sum(T21356.ORDER_VALUE) as c1,
     T21309.DIVISION_CODE as c2
from
     DIVISION T21309,
     DWH_SALES_ORDER_OVERVIEW T21356
where ( T21309.DIMENSION_KEY = T21356.DIVISION_KEY )
group by T21309.DIVISION_CODE)
select distinct case when SAWITH0.c2 is not null then SAWITH0.c2 when SAWITH1.c2 is not null then SAWITH1.c2 end as c1,
     SAWITH0.c1 as c2,
     SAWITH1.c1 as c3
from
     SAWITH0 full outer join SAWITH1 On nvl(SAWITH0.c2 , 'q') = nvl(SAWITH1.c2 , 'q') and nvl(SAWITH0.c2 , 'z') = nvl(SAWITH1.c2 , 'z')
order by c1As you can see one select (SAWITH0) for the first fact table C_CONSUMERS_SALES and one select for the second fact table DWH_SALES_ORDER_OVERVIEW (SAWITH1 ) and the two statement are joined with a full outer join.
I ask me why you have the three select (SAWITH0,SAWITH1 and SAWITH2). Can you please paste the complete SQL performed ?
Can you tell us also which SQL is performed if you select only the columns from one fact table and not for the other ?

Getting Data from C++ STL Vector into Java Vector

Hi All,
I have been involved in a project recently to port a lot of C++ code into Java. Testing the ported Java code has been done in isolation with JUnit and works fine, but we would like to test all the ported code. To do this we aim to call the ported (Java) methods from C++ using JNI.
I have read a lot of the documentation from Sun on the JNI and can access and set Java methods that only contain primitive types without any problems. However what I cant seem to be able to achieve is passing aggregated C++ classes to Java.
Java
public void translation_unit_2( Vector v ) { \* code *\ }and somewhere in C++
jobject actions; // Is initialized
std::vector<Node> test ; // Node class may contain other objects
jmethodID tmp = env->GetMethodID(env->GetObjectClass(actions), "translation_unit_2", "(Ljava/util/Vector;)V");
env->CallObjectMethod(actions, tmp, test);Now obviously what I have posted there doesnt work, but can anybody point me
in the correct direction to pass the Vector and its Data in C++ to Java?
None of the Java methods are native, because the eventually the whole system
will be operating solely in Java, but the testing at this stage is quite important.
If this is an impossible task then please say so also, any help will be appreciated !
Thanks,
Mark Hennessy

Thanks for the reply and I understand that running an iterator
over the vector would be the way the get the data out of the C++ Vector.
However that still leaves me with the question of mapping an arbitrary
C++ class ( which in the case of the example above would be a Node class which is
composed of other aggregated classes ) to a jobject such that I can pass
the data easily to Java throught JNI?
Is this possible or would I have to decompose each and every class to its most
primitive types and pass them over to Java and reconstruct them on the Java side?

Getting result from a telnet command through Java

Hi,
I've been using a set of classes found here: http://javatelnet.org/
to do telnet through Java in a non-interactive mode.
However I've got a problem when retrieving the result of a command sent to the remote host: the classes read the stream until the prompt is encountered; my problem is I must execute commands on several remote hosts, and the prompt is not necessarily the same on all hosts.
Is there a simple means to establish a telnet connection through Java and retrieve the result of the commands?
Any help would be appreciated.

Thanks again, this is a very good article
I see it is still the same strategy to get the result of a command : wait 'til the prompt is sent. Maybe there is just no other way to get it .
But as I don't know the prompt on the different hosts I have to query, this won't do it.
The article gave me an idea though : I only need to count the files in a directory on the remote host; until now I was trying to send the 'ls | wc -l' command by Telnet.
Maybe I can simply do it by FTP (retrieve the list of files, and then count the lines with JAVA).

Getting the exace application page openning through java...

NIO Socket implementation - delay between select and get data from socket

Hi all,
I have implemented a internal CallAPI for RPC over a socket connection. It works fine but if there are more than five clients and some load I have the phenomena that the READ selector returns a SelectorKey but I did not get any data from the socket.
My implementation is based on NIO has following components:
+ Accept-Thread
Thread handles new clients.
+ Read-Thread
Thread handles the data from the socket for the registered client. Each request is handled in an own Process-Thread. A Thread-Pool implementation is used for processing.
+ Process-Thread
The Process-Thread reads the data from the socket and starts the processing of the logical request.
In my tests I get the notification of data at the socket. The Process-Thread want to read the data for the socket, but no data are available. In some situations if have to read about 20 times and more to get the data. Between each read attempt I have inserted a sleep in the Process-Thread if no data was available. This have improved the problem, but it already exists. I tested the problem with several systems and jvm's but it seams that it is independent from the system.
What can I to do improve the situation?
I already include the read implementation from the grizzly-Framework. But it doesn't improve the situation.

    }Thanks for your time.

I've commented on that blog before. It is rubbish:
- what does 'overloading the main Selector' actually mean? if anything?
- 'Although this not clearly stated inside the NIO API documentation': The API documentation doesn't say anything about which Selector you should register channels with. Why would it? Register it with any Selector you like ...
- 'the cost of maintaining multiple Selectors can reduce scalability instead of improving it' Exactly. So what is the point again?
- 'wrapping a ByteBuffer inside a ByteBufferInputStream:' Code is rubbish and redundant. java.nio.channels.Channels has methods for this.
There is no a priori advantage to using multiple Selectors and threads unless you have multiple CPUs. And even then not much, as non-blocking reads and writes don't consume significant amounts of CPU. It's the processing of the data once you've got it that takes the CPU, and that should be done in a separate thread.
So I would re-evaluate your strategy. I suspect you're getting the channel registered with more than one Selector at a time. Implement it the simple way first then see if you really have a problem with 'overloading the main Selector' ...

How to post and get data from server using Get Webrequest

Hi:-)
I'm trying to send a username and password argument my server and the server is suppose to send some string back. The following code, that I got of the web, just dies. I think this line:
HttpWebRequestpreq = result.AsyncState
asHttpWebRequest;
is null. Can you kindly fix this for me? Thank you in advance:-)
