We are interested in installing the Oracle 9i Lite Database standalone for Windows 2000. Can you send me the instructions that you mentioned below in a previous response? In addition, I need to know the size of the database footprint.
Thanks,

JDBC API ( JSR 169 ) Implementation for accessing oracle lite database
We are developing an application using IBM J9 (CDC and Foundation Profile) on Pocket PC 2003 environment with SWT as the front end development. We are using Oracle Lite 9i as the Client database.
We have sucessfully installed Oracle Lite and was able to create tables in the database.. however we could not find the JDBC API (java.sql and javax.sql packages which is JSR 169 JDBC 2.0/3.0) inorder to load the JDBC driver(OLITE40.jar) and access the oracle Lite Database on Pocket PC.
IBM J9 Micro Environement does not have this support.
I am wondering if Oracle provides this implementation.
If not is there a get around.
the client database is crucial to the application and i would really appreciate an answer to our problem.Check out
http://groups.google.com/groups?hl=en&lr=&threadm=cjgl3g%248hhm%241%40news.boulder.ibm.com&prev=/groups%3Fhl%3Den%26lr%3D%26ie%3DUTF-8%26group%3Dibm.software.websphere.studio.device-developer
I have had the same issue before.

Oracle 9i lite application development using java
hi all,
I want to develop a applcation which interacts with the 9i lite database in java.Is there any emulator which will help me in developing this on a windows 2000 machine or winnt machine?
i tried developing it in eVB but the emulator which come along with it does not support the 'oladoce' object..
please if anybody has done something on this please help .. this is very urgent..
thanks ..,
sreekanth sreedharanOracle 9i Lite is a multi-platform product and you need to specific the target OS for the database and the version of java.
If you are planning to run your application in Win2000 you will have no problem using Oracle 9i Lite with the supplied
jdbc drivers and any java development environment for J2SE. What you get is a laptop platform that works while not
connected to the Internet
If you are trying to using Oracle 9i Lite on the Palm with J2ME development on windows, it works fine with the Palm Emulator
but I am not sure that the jdbc drivers are available for J2ME yet and I have not used them as I have for J2SE on windows
I am also very interested in developing java applications for the palm using Oracle 9i Lite and I would appreciate feedback
on the jdbc and other required sql extensions for the sun java cldc
If you are talking about the PocketPC or other WinCE, I cannot help you but I have used Personal Java on WinCE but not yet
attempted Oracle 9i Lite on those platforms -
How to create a table in Oracle Lite database?

KhaleelHI James,
Thank you so much. I am able to create table and insert rows and able to select them too. However I am not able to use these tables in my BPEL process for my practice. The DB adapter is throwing some error, any idea?

Converting between tables in an Oracle Lite Database
We have a standalone application that uses Oracle Lite. A requirement we have from a new customer is to use their Oracle Lite database structure or to come up with a mechanism that sends the data between the 2 different structures.
Both the structures reside in the same database.
Initial thoughts were to write triggers on both structures that convert the data or to use XML / XSL and treat them as seperate apps.
However, I'm wondering if there is a different way. Do Oracle provide any tools that can help with mapping between 2 different structures that hold the same domain data?
Anyone got any better ideas?

I have been using an app developed in VB.net for accessing the Oracle Lite Database from the client machine. Can anyone please help me out how to set the Connect String in the config file of my front end app to access the Oracle Lite Database from my client machine. Do anyone have the syntax of the connect string to access the lite database in client machine.
Thanks a lot in advance.Hi...

Client Upgrade issue in Oracle Lite Database 10g 10.3.0.3.0
Hi all,
Details: My Environment is Oracle Database 11g R1(11.1.0.6.0) With Oracle Lite Database 10g R3(10.3.0.3.0) on Windows 2003 Server R2 SP2.
Recently i have upgrade my oracle lite database from 10.3.0.2.0 to 10.3.0.3.0 and also applied recent opatch (p12812978_103030_Generic.zip). Upgrade and installation of opatch got successfully completed. When i tried the client synchornization for the very first time (FCS and Data Download) FCS and Data Download got Successfully completed but the problem is usually Once the FCS and Data Download Got Completed , Screen goto webtogo home page but in my case i am getting a screen name called "client upgrade" with options yes or no if choose yes it prompting please wait screen nearly for 1 hours i am not getting any response from the screen. if choose no simply it goto my webtogo home page. Please Note before choosing the yes option i have checked what version i am currently having it show 10.3.0.3 i don't know why it asking for the client upgrade. Please Advice me on this how to avoid this screen (Client Upgrade).
Thanks
ShanHi,
i am not upgrading the existing environment of Oracle Lite Client i am creating a new environment which doesn't have the Oracle Lite Client. In the document itself they have mentioned like this "These steps assume that you have a 10g Release 1 or 2 Branch Office environment already configured and synchronized. If you do not have this environment currently configured, you do not need to upgrade." To be Clear What i am doing is with help Oracle Lite Branch Office i will be downloading a user from Mobile Server for that i have to do the following
1.FCS(Fresh Client Setup for that i have to run the setup.exe which is coming for Oracle Lite Branch Office) and
2.Data download (Data will be get download from Mobile Server in the form of odb),
3. Usually Once the FCS and Data Download got completed, the screen will goto the webtogo home there i can see my branch offlice applications.
4. But in my case i am getting prompted by screen and the screen name called "Client Upgrade" with options yes or no if i choose yes screen got hanged else if i choose no then only screen moving the webtogo home page. Say can u r having existing environment in your machine due to some reasons u have upgrade or u have installed optach on the mobile server in that case while doing the client synchronication we can do the client upgrade by running the update.exe becasue client side will having the old binary file we need to renew it.
5. But I am not upgrading the existing environment. I am creating a new environment which means i am doing a fresh client setup and synchronization for the very first time. While doing the FCS on my client side for the very first time i will be getting the latest binaries rite then why the screen is moving to client upgarde page i don't have any idea on this.
Please Advice.
Thanks

Sequencing and Trigger on Oracle 9i lite database
We created a schema (TESTSCHEMA) on Oracle 8.1.7 Enterprise edition and have a created a trigger which will use the sequence object to generate primary key for the table (TEST_TABLE)
Sequence creation:
CREATE SEQUENCE TESTSCHEMA.TEST_TABLE_SEQUENCE START WITH 6000 INCREMENT BY 1 MINVALUE 6000 MAXVALUE 6999 NOCACHE NOCYCLE NOORDER ;
Trigger creation:
CREATE OR REPLACE TRIGGER TEST_TABLE INSERT BEFORE INSERT ON TEST_TABLE FOR EACH ROW
DECLARE
pkValue NUMBER;
BEGIN
pkValue := 0;
Select TEST_TABLE_SEQUENCE.NextVal into pkValue from dual;
:NEW.TEST_KEY := pkValue;
END TEST_TABLE_INSERT;
We have created a snapshot of the schema on mobile server, synchronized the data with the client (Win32 for testing purpose).
The trigger works fine on the server, but when I run the same query on the lite database with msql it gives me an error:
[POL-3221] null key in primary index
I was wondering if Sequence generation and Triggers are supported on Oracle 9i lite database ? Or am I missing out something ??
Any information/ help is appreaciated
Thanks
NeerajYou can't use SAVEPOINT / ROLLBACK TO SAVEPOINT statements in the database trigger:
ORA-04092: cannot SET SAVEPOINT in a trigger
ORA-04092: cannot ROLLBACK in a trigger
I am not sure what you need exactly, but you can try this:

Can i connect to lotus domino database in my java environment
Hi javaites,
I want to know if i can connect to domino database from my java environment. i need to pick e-mail address of staffs from lotus notes database. if possible how can i go about it.
thanksYes, you can connect to a database on a Lotus Domino server. The classpath must include Notes.jar (local) or NCSO.jar (remote) - and the DIIOP (Domino IIOP) task on the Domino server must be running.

No information popped up in the console window before, during, or after the error was given. The program compiled and ran and therefore no error information was provided in the complier window either.
If I am missing what you are asking then please provide instructions as to how to find this error information. You are posting the error message for the exception but not printing the stack trace.
Far as I can tell you are printing more information with each exception (for example "Exception creating Users table") but you did not post what that was, that info would localize the problem.
As a guess the problem is when you extract the fields via the query. You are using named values rather than indexes and you use "select *" rather than specifically naming the columns. Some databases (for example Oracle), require that using names must be in exactly the same order as the query returns them. You have no idea what that order is because you use "select *"
Finally it would be a LOT easier if you wrote classes that did nothing but the database operations. NO GUI CODE. You then test that code to make sure it works. Once that code works then you write gui code which uses those classes. Besides making it easier to understand you are also more likely to get assistance since there is less code to look at. -
Open Innovation Call: abap interpreter written in java
Like part of the Open Innovation Call initiative: /people/ignacio.hernndez/blog/2006/12/22/open-innovation-call ,
I begin this forum thread to open the discussion about "JAbap project":
I know JRuby...is there something like a abap interpreter written in java? ..java and abap using the same virtual machine....?Hello I have the same problem, were you able to execute the WS through the JS code now?
I would like to call an ABAP WS using JavaScript to return complex structures that I would like to manage directly with JS.
I tried with this code and I get the error "RaiseError: Acrobat Raise." when the request is executed:
var WSUrl = "http://<server>:<port>/sap/bc/srt/wsdl/bndg_4D15C75529330AF1E10000000A150429/wsdl11/allinone/ws_policy/document?sap-client=500";
var VendorNumber = xfa.form.DATA.DATAFLOW.SF_HEADER.VENDOR_NUMBER.rawValue;
try {
// Create request structure, read Input out of text field
var request = {
"urn:sap-com:document:sap:soap:functions:mc-style:ZWsTest" : {ILifnr: VendorNumber}
SOAP.wireDump = true;
// Call web service using SOAP object
var response = SOAP.request ({
cURL: WSUrl,
oRequest: request
// cAction: "urn:sap-com:document:sap:soap:functions:mc-style"
} catch (e) {
xfa.host.messageBox(e.toString()); //pop-up "TypeError:service.CelsiusToFahrenheit is not a funciton"
with this other code I get the error "SOAPError: CX_ST_MATCH_ELEMENT:XSLT exception.System expected element 'ILifnr'":
try {
var myProxy = SOAP.connect(WSUrl);
var result = myProxy.ZWsTest( { ILifnr: VendorNumber } );
xfa.form.DATA.DATAFLOW.SF_HEADER.E_DESCRIPTION.rawValue = result;
// Display the response in the console:
console.println("Result is " + result);
} catch (e) {
xfa.host.messageBox(e.toString()); //pop-up "TypeError:service.CelsiusToFahrenheit is not a funciton"
in the second option, if I make the field ILifnr optional the call is succesfully performed but the parameter is not passed to the WS. So the call is working.
Using stand-alone LiveCycle designer 8.1 and Adobe Reader 8
Any suggestions?
Many thanks,
G.

How to ensure applet is written in java card?
Hi all,
I have written a java card applet, in which i am using the Biometry API of java card to enroll a fingerprint template in java card. Code is attached below:

Problem :
I have developed this program in Netbeans using java card plug ins. when i am running this program, all the required CAP files and EXP files are generated.
Now, i have to write this applet on java card through a card reader. My card reader is installed in an embedded system GeoAmida with IP 192.133.133.2 and port number 6789.
I have used the following settings for my java card device in Netbeans:
Host : 192.133.133.2
Server URL: http://192.133.133.2:6789/
Card Manager URL: http://192.133.133.2:6789/cardmanager/
HTTP port: 6789
The output shows me that Instances of this program has been successfully has been created on java card.
But the problem is how can i ensure that my applet is been successfully installed on the java card?
The code of host application program, accessing the developed java card applet is given below (it is written in C):
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <smartcard.h>
int main()
int ret, i, smartcard;
unsigned char applet_id[100], apdu_len, apdu[300],response[300]={0};
smartcard_info *context;
smartcard=CONTACTLESS;
//smartcard=CONTACT_BOT;
if((context = smartcard_init(smartcard)) == NULL){
printf("Smartcard Initi. Failed\n");
return 0xBB;
/* checking for smartcard */
while (1){
if(ret=smartcard_is_present(context, smartcard)!=0)
sleep(1);
else
break;
printf("Selecting Applet \n");
i = 0;
applet_id[i++]=0x00; applet_id[i++]=0xA4; applet_id[i++]=0x04; applet_id[i++]=0x00; applet_id[i++]=0x06;
applet_id[i++]=0xA9; applet_id[i++]=0xBF; applet_id[i++]=0xA2; applet_id[i++]=0xB6; applet_id[i++]=0xB1; applet_id[i++]=0x3E; applet_id[i++]=0x7F;
if ((ret=smartcard_select_applet(context, smartcard, applet_id, i))!=0){
printf("select applet failed %02x\n",ret);
return ;
printf("Applet Selection Success \n");
#if 1
i=0;
apdu[i++]=0xCF; apdu[i++]=0x10; apdu[i++]=0x04; apdu[i++]=0x04; apdu[i++]=0x7F;
//apdu[i++]=0x3F; apdu[i++]=0x00;
apdu_len = i;
printf("Sending APDU command\n");
if ((ret=smartcard_apdu(context, smartcard, apdu, apdu_len, response))!=0){
printf("apdu failed %d\n",ret);
//return;
}else
printf("APDU Success\n");
//printf("\n");
#endif
smartcard_deinit(context);
return 0;
}The output of this program is showing me that applet is been successfully selected, but APDU selection failed. Please solve this problem as soon as possible, because my project is deadline is not very much far.
Thanks in advance.
Mukul GuptaHi Shane,
I am getting error 6a86 which means that value of P1 is less than 1 or more than 8, and we have to change its value to any in between 1 to 8. I did that also but error still remains :(
Please tell me what is reason behind this error. And, i'll try out your previous solution today, Thanks for it. -
I'm writing a Java program that needs to query a Microsoft Access database. I'm not sure how to do this. Someone said to use ODBC drivers but I don't know what these are. Any clarification/ideas would be appreciated.
There are a few easy step to set up a connection to your database in your java program.
1. establish an odbc data source in windows control panel (may be under Administrative tools).
2. you need to import the java.sql package.
3. you need a connection, so type the following into your database class:
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
connection = DriverManager.getConnection("jdbc:odbc:/*your data source name goes here*/");
catch (ClassNotFoundException exception)
System.err.println("Failed to load JDBC/ODBC driver");
exception.printStackTrace();
System.exit(1);
catch (SQLException exception)
System.err.println("Unable to connect");
exception.printStackTrace();
System.exit(1);
}4. Find an SQL tutorial on the web.
5. For each query/update etc create a Statement object using the following code:
try
Statement statement = connection.createStatement();
/* now use the remainder of this try block to execute your query. Each database query returns a ResultSet object */
ResultSet resultSet = statement.executeQuery("/*your query string goes here*/");
/* the next() method in ResultSet returns true if there are any more records, like an iterator. Therefore, you know if there are any results or not*/
if (resultSet.next())
/* If your query was a 'SELECT * FROM ...etc' then you will get a whole row from the table(s) within the database. if you need to extract a number from that record and you know the column number, then use the following */
int id = resultSet.getInt(1);
/* where 1 corresponds to the first column in the table, and so on. Ifyou want to extract a String, the use the getString() method*/
catch (SQLException exception)
}That's basically the easiest way to go about it (I think). Best to consult a book for a more in-depth look. Try Java - How to Program, by Deitel and Deitel (available at www.deitel.com). I found this very useful. -
Performance problem in data replication program written in java
Dear all,
I need your valuable ideas on improving below logic on replicating data fromDB2 to Oracle 9i.We have a huge tables in DB2 to replicate to Oracle side.For one table this taking lot of time.The whole app' is written in java.The current logic is Setting soft delete to specific set of records in oracel table and Reading all records from DB2 table to set only these records in oracle table to 'N' so that deleted records got soft deleted in oralce side.The DB2 query is having 3 table join and taking nearly 1minute.We are updating the oracle table in batch of 100000.For 610275 record update in batch mode it is taking 2.25 hours which has to be reduced to <1hour.The first update to all Y and second update using DB2 query is taking 2.85 hrs.
Do you have any clever idea to reduce this time?? kindly help us.we are in critical situation now.Even new approach in logic to replicate also welcome..hi,
just remove joins and use for all entries.
if sy-subrc = 0.
use delete adjacent duplicates from itab comparing key fields.(it will increase performance)
then write another select statement.
endif.
some tips:
Always check the driver internal tables is not empty, while using FOR ALL ENTRIES
Avoid for all entries in JOINS
Try to avoid joins and use FOR ALL ENTRIES.
Try to restrict the joins to 1 level only ie only for tables
Avoid using Select *.
Avoid having multiple Selects from the same table in the same object.
Try to minimize the number of variables to save memory.
The sequence of fields in 'where clause' must be as per primary/secondary index ( if any)
Avoid creation of index as far as possible
Avoid operators like <>, > , < & like % in where clause conditions
Avoid select/select single statements in loops.
Try to use 'binary search' in READ internal table. Ensure table is sorted before using BINARY SEARCH.
Avoid using aggregate functions (SUM, MAX etc) in selects ( GROUP BY , HAVING,)
Avoid using ORDER BY in selects
Avoid Nested Selects
Avoid Nested Loops of Internal Tables
Try to use FIELD SYMBOLS.
Try to avoid into Corresponding Fields of
Avoid using Select Distinct, Use DELETE ADJACENT
