Two questions on dynamic parameter from java API point of view
Hi,
We have a requirement for dynamic parameters in crystal reports that need to be executed in java application. Since, crystal java framework do not support the dynamic parameter execution (please correct me if I am wrong), we plan to execute explicitly the query for getting the dynamic values of such dynamic parameters before listing the parameters in java application.
The query for the dynamic parameter will be given in the field 'Prompt Group Text' of the parameter.
I coudl not get hold of these details from java api. So please some one help me out.
Environment - Crystal X1 R2 with java libraries
1. How can we identify a parameter is a dynamic one?
2. How to get the 'Prompt Group Text' field value?
Any suggestions welcome.
Thanks,
Ratan.
There are these two methods in the Business Objects Enterprise SDK Developer Libary:
byte[] getDynamicCascadePromptData()
Returns a collection that contains dynamic cascading prompt data.
java.lang.String getDynamicCascadePromptGroupID()
Returns a dynamic cascade prompt group ID.
For more information on what is available through available SDK's, please refer to the following link:

Did you ever find a solution to your problem?
My situation is that I'm running a process that grabs data from a salesforce.com web service and dumps some of the data back into my local database. The process croaks after processing 850 or so records. I have also increased my PermSize memory to 512M.
Any ideas why all of a sudden after processing that many records it would stop working?
Thanks,

Lost message from server's point of view
Hi All
Following situation:
The JMS-Provider sends a JMS-Message. The message is entirely in the wire and is still flying to the consumer. Before the message arrives to the consumer, the network connection fails, so the client does nothing know about the send message.
From the server’s point of view the message was successfully sent but not acknowledged yet. The server waits for an acknowledge and doesn’t undertake redelivery, because the consumer session on the server is still living.
From the consumer point of view the message was not sent so the client has nothing to ack, so we have some “deadlock”.
The question is – how does server recognize such situation (short connection fail, deadlock) and what does it undertake to guarantee the delivery?
Thank you.The JMS-Provider sends a JMS-Message. The message is entirely in the wire and is still flying to the consumer. Before the message arrives to the consumer, the network connection fails, so the client does nothing know about the send message.

From the consumer point of view the message was not sent so the client has nothing to ack, so we have some “deadlock”.
The question is – how does server recognize such situation (short connection fail, deadlock) and what does it undertake to guarantee the delivery?If the "network connection fails" whilst sending a message then the server (and probably the client) will almost certainly receive a SocketException. A message is unlikely to simply disappear on the wire without at least one end of the socket getting an exception of some kind, and if the socket is simply hanging for some reason then most JMS providers would have a means to detect this (e.g. by sending periodic packets down the wire to check it is still alive).
But ultimately, if a persistent message is sent to a consuming client and the message is not acknowledged (or the transaction committed) then the server will eventually redeliver it. JMS doesn't define exactly when an unacknowledged message is redelivered, but it typically wouldn't happen until the consumer in question has closed.

JMS - Useful from an international point of view?
Hi everyone,
I was wondering if JMS could be useful from a legislative point of view. I mean could it be useful when two companies situated in different countries communicate? Does JMS make this communication easier/better in any way?
Hope someone is able to help me :)JMS is ideal for the loosely coupled communications which the integration of two different companies or governments would require. However, message oriented middleware has typically been a behind-the-firewall technology. So, while most JMS vendors support messaging over the firewall, it is not their primary focus. Web services are better suited to the type of over-the-Internet integration you are describing. The issue with this, however, is that web services lack transactional support. I think they are working on that though.

Improving audio quality from a subscriber point of view
Hi,
I am building an application that requires audio chat. When the chat is happening between an Android user and a PC user, the PC user can hear clearly when the Android user speaks. However, when it is the other way around, the Android user hear distorted sound,with noises. Is there any way to improve audio received from a subscriber point of view?
Please advice, thanks!

The Android device is a Samsung Galaxy S i9000 and it is running AIR 2.6, attached below is a snippet of the code related to the audio i am using
<mx:Button x="121" y="700" height="34" width="117" label="Audio" toggle="true" id="audioButt"
click="(audioButt.selected) ? audioPub.publish(): audioPub.stop()" includeIn="LoggedIn"/>
<mx:Button x="242" y="700" height="34" width="117" label="Quality" toggle="true" id="audioButt1" includeIn="LoggedIn"
click="(audioButt.selected) ? audioPub.microphoneManager.encodeQuality = 3 : audioPub.microphoneManager.encodeQuality = 4"/>
<rtc:AudioPublisher id="audioPub" codec="{SoundCodec.SPEEX}" useEchoSuppression="true" silenceLevel="0" />
<rtc:AudioSubscriber/>
I think the problem is related to the script I am writing,I created a button called Quality to reduce the encodeQuality of my PC microphone, will it helps to improve the audio recieved from my Android device?Please advice, thanks!

Which design is best from a performance point of view?
Hello
I'm writing a small system that needs to track changes to certain columns on 4 different tables. I'm using triggers on those columns to write the changes to a single "change register" table, which has 12 columns. Beacuse the majority of tracked data is not shared between the tables, most of the columns will have null values. From a design point of view it is apparent that having 4 separate change register tables (one for each main table that is being tracked), would be better in terms of avoiding lots of null columns for each row, but I was trying to trade this off against having a single table to see all changes that have been made across the tracked tables.
From a performance point of view though, will there be any real difference whether there are 4 separate tables or 1 single register table? I'm only ever going to be inserting into the register table, and then reading back from it at a later date and there won't be any indexes on it. Someone I work with suggested that there would be more overhead on the redo logs if a single table was used rather than 4 separate tables.
Any help would be appreciated.
DavidThe volumes of data are going to be pretty small,
maybe a couple of thousand records each day, it's an
OLTP environment with 150 concurrent users max.Consider also the growing of data and if you'll put data constantly to an historical db or if the same tables will contain the increasing number of record.
The point that my colleague raised was that multiple
inserts into a single table across multiple
transactions could cause a lot of redo contention,
but I can't see how inserting into one table from
multiple triggers would result in more redo
contention that inserting into multiple tables. The
updates that will fire the triggers are only ever
going to be single row updates, and won't normally
cause more than one trigger to fire within a single
transaction. Is this a fair assumption to make?
David
I agree with you, the only thing I will consider, instead of redo problem, is the locking on the table that could be generated when logs of different tables will have to be put in a single table, i mean if after insert of a log record you could need to update it....
In this case if 2 or more users have to update the same log you could have problems. -
How to get the parameter from Java Script into the Parameter crystal Report
Hi All,
Crystal Report is integrated with Oracle 10g. I created the base SQL query for col1, col2, col3 and col4. Java Script pass parameter value (185) to Col1.
My question is how to create crystal report to make Col1 as parameter and how to get the parameter value 185(Col1) from Java Script. Is there any additional code I need to include in the crystal report?
FYI.
Java script sends the right parameter value.There is no issue in java script.
This is an automatic scheduled process when batch runs, Java script should pass the parameter value and the crystal report should get the value and produce the output report.Not sure if this is an application question or if you are trying to hook into Crystal Reports parameter UI? If the later then no option other than report design. If an application then I can move this to the Java Forums.
If you are asking how to alter the parameters I suggest you remove the Java reference and post a new question so it's not confusing the issue.
Please clarify? -

End SubHow many tables is there in the report? And, do you have any subreports? I'd recommend gaining experience with this by creating as simple a report as possible - one table - one field, create a recordset, pass that to this report. Does it work? It should. Now we have a bit of confidence and experience, so increase the complexity. But let me know answers to the two Qs above.

How to call sql procedure with parameter from java
Hello,
i am trying to call one sql procedure with two parameters from java.
the first parameter is In parameter, the second is OUT.
the return value of this java method should be this second parameter value.
the following is my java code:
protected String getNextRunNumber() {
String runnumber=null;
String sql = "{call APIX.FNC_SST_EXPORT.GET_NEXT_RUNNUMBER (?,?)}";
CallableStatement state = null;
try{
Connection con= getDatabaseConnection();
state = con.prepareCall(sql);
state.setString(1, m_appKeyExport);
state.registerOutParameter(2,Types.NUMERIC,0);
state.execute();
ResultSet resultR = (ResultSet)state.getObject(2);
while (resultR.next()) {
runnumber=resultR.getBigDecimal(1).toString();
catch (SQLException e){System.out.println("You can not get the export next run number properly");}
return runnumber;
i got error message like:
java.lang.ClassCastException: java.math.BigDecimal
As far as i knew, if the parameter is number or decimal, we should give also the paramer scale to the method: state.registerOutParameter(), but i still get this error message.
Please help me to solve this problem.
Thanks a lot.state.execute();
i try to use debug to find the problem, in this line, i saw
OracleCallableStatement(OraclePreparedStatement).execute() line: 642 [local variables unavailable]
is this the problem? -
Calling Stored Procedure with table type as In parameter from Java
Hi Everyone,
Can anyone help me with the sample code to call a stored procedure having input parameter of Table type (consisting of multiple fields) from Java. This job is currently being done by a BPEL process.
We want to implement the same using Java.
Any sample code will be really helpful.
Thanks & Regards,
VikasTo start using a blob you have to insert it into the database and then get it back. Sounds weird but that is how it is. Here is a very simple program to do this:
#include<occi.h>
#include <iostream>
using namespace oracle::occi;
using namespace std;
int main()
try
Environment *env = Environment::createEnvironment(Environment::OBJECT);
Connection *conn = env->createConnection("hr","hr","");
string stmt1 = "insert into blob_tab values (:1) ";
string stmt2 = "select col1 from blob_tab";
Blob blob(conn);
blob.setEmpty(conn);
Statement *stmtObj = conn->createStatement(stmt1);
stmtObj->setBlob(1,blob);
stmtObj->executeUpdate();
conn->commit();
Blob blob1(conn);
Statement *stmtObj2 = conn->createStatement(stmt2);
ResultSet *rs = stmtObj2->executeQuery();
while(rs->next())
blob1 = rs->getBlob(1);
string stmt3 = "begin my_proc(:1) ;end;";
Statement *stmtObj3 = conn->createStatement(stmt3);
stmtObj3->setBlob(1,blob1);
stmtObj3->executeUpdate();
catch (SQLException e)
cout << e.getMessage();
/* The tables and procedure are primitive but ok for demo
create table blob_tab(col1 blob);
create or replace procedure my_proc(arg in blob)
as
begin
-- just a putline here. you can do other more meaningful operations with the blob here
dbms_output.put_line('hello');
end;
}Hope this helps.
Thanks,
Sumit
