Accessing connection from java and generated code

In JDeveloper 10.1.2.x I set up a connection and selected a stored procedure and generated java to call the stored proc. All good.
Now, in a web service application I want to call the method in that class that was generated.
So, the generated class has setConnectionContext(), getConnectionContext(), etc methods. I don't know how to use them. What is a ConnectionContext?
How do I provide the database connection information and call the method in the generated code that I need?
My Oracle AS server has a datasource configured that is the one I would like to use, but I don't know how to 'access' it via java in the context of this generated class.
I am deploying to Oracle AS 10.1.2,
thanks

Hi, well CSV is not currently an Excel file, it is a Comma Separated Values
file which can be read through Excel.
Now, if you wish to remove the header, I would purpose that you develop an
application that reads the CSV file, as it is mere text, and that it also reads
another file (lets call it confirguration.txt) in which you determine the pattern
you want to remove, then you just read your report and if a string line
matches the pattern you defined in the configuration.txt file, then you simply
erase it.
And if you keep interested in reading real Excel files (xls), I would
recommend you use POI-HSSF API from Apache.org
http://jakarta.apache.org/poi/hssf/index.html
Hope this helps, cya around.

Accessing excel from java code

Hello
our system uses reportNet to generate reports. When reports are generated in CSV format we have a problem:
Report consists of people (can be more than one) so under name column we have same name in more than one row. BUT if more than one name is suppose to be in the CSV report then the header (column names row) is again printed.
so for example if i requested rpeort for two names A and B (reportNet uses same template which is executed twice) then report will look like this
Name (header - column name)
A
A
A
A
A
Name (header - column name)
B
B
B
B
I want to be able to remove the second header that comes before B starts.
so i was thinking i would be able to access this excel sheet from java. and keep record of every row. If the row changes from A to B...i delete the previous row (which would end up being the second header).
Can this be done thru java. I havnt before accessed excel sheets from java so any pointers would be greatly appreciated.

Jintegra problem - accessing Matlab from Java??

Hi:
Sorry if this post doesn't belong here!!
I am accessing Matlab from JAVA using JIntegra for COM. I tried running the example in their website.
(http://j-integra.intrinsyc.com/support/com/doc/other_examples/Matlab.htm)
I have also posted the example below. I am using their trial version and have included all the jars as said. I get the an unexpected output (all zero's) for reading a variable in the matlab workspace. I don't understand why I get this. Can anyone let me know if this runs for you??
Thanks
Pavan
Example code from Jintegra website:
public class MatlabExample {
public static void main(java.lang.String[] args) throws Exception {
try {
// DCOM authentication: Make sure NT Domain, NT User, NT Password are valid credentials.
// Uncomment this line if MatlabExample.java remotely accesses MATLAB :
// com.linar.jintegra.AuthInfo.setDefault("NT DOMAIN", "NT USER", "NT PASSWORD");
// Create the MATLAB object
// Specify host name or IP address of MATLAB machine as parameter if
// MatlabExample.java remotely accesses MATLAB.
// mlapp.MLApp mlApp = new mlapp.MLApp("123.456.789.0");
mlapp.MLApp mlApp = new mlapp.MLApp();
String result = mlApp.execute("a = [1 2 3 4; 5 6 7 8;]");
System.out.println("Execute result is " + result);
double mreal[][] = new double[2][4];
double mimage[] = new double[0];
mlApp.getFullMatrix("a", "base", new Object[]{mreal}, new Object[]{mimage});
for (int i = 0; i < 2; i++) {
for (int j = 0; j < 4; j++) {
System.out.println(mreal[i][j]);
} finally {
com.linar.jintegra.Cleaner.releaseAll();

[JDBC][ODBC] How to compact access database from Java ?

Hello,
I'm developping a java applcation wich is connected to an MS Access file database.
For now, I don'y compact it but it would be better.
So How can I compact an access database from Java ?
thanks :)

Hi ypiel,
Try this:
1) Download JETCOMP.exe (freeware from Microsoft);
2) Put the following code in your app (assuming your database file name is: "DB.mdb"):
try {
File current = new File("DB.mdb");
File backup = new File("BACKUP.mdb");
if (current.renameTo(backup)) {
Runtime.getRuntime().exec("jetcomp -src:BACKUP.mdb -dest:DB.mdb");
} catch (Exception e) {
System.out.println(e.getMessage());
Best regards,

Calling MS Access queries from Java

Anyone have any idea if it's possible to call MS Access queries from Java? I have a client who is insistent on keeping MS Access for their database, and it'd be nice if I didn't have to receate all their queries in Java.
I've successfully connected to and queried the Access MDB, but I need to know if it's even possible to execute the stored MS Access queries they have setup in the database.
Thanks!

I need an suitable InitialContextFactory to connect from java to OID

Hi,
I have a problem to connect from my application java to OID, I was using the following InitialContextFactory in my code in this way:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.ApplicationClientInitialContextFactory");
env.put(Context.PROVIDER_URL, "ormi://192.168.3.112:3061/dn=fedco,dn=com");
but it gives back the following error to me:
Problem looking up : javax.naming.NamingException: META-INF/application-client.xml resource not found (see J2EE spec, application-client chapter for requirements and format of the file).
I have been looking for about the xml files but I have found that they are necessary when one works with EJBs which is not my case, I need to know if I am using the appropriate InitialContextFactory or if another one is the appropriate for this case.
Please, help me.
Thanks.

Hi,
Have a look at my response to this thread :InitialContextFactory to connect from java to OID
Let me know how you go.

How to get return value from java and read by other application?

i want to read return value from java and the other application read it.
for example:
public class test_return {
    test_return(){
    public int check(){
        return 1;
    public static void main(String args[]){
       new test_return().check();
}from that class i make as jar file. How to read the return value (1) by other application?
thx..

If your installer is requiring some process it invokes to return a particular value on failure, then the installer is seriously broken. There are a bazillion commands your installer could invoke, and any of them could fail, which in turn could invalidate the entire install process, and any of them could return any value on failure. The only value that's consistent (in my experience) is that zero means success and non-zero means failure, with specific non-zero values being different in different programs.
About the only control you have over the JVM's exit code is that if your main method completes without throwing an exception, the JVM will have an exit code of 0, and if main throws an exception (either explicitly or by not catching one thrown from below), it will be non-zero. I'm not even sure if that's guaranteed, but I would guess that's the case.
EDIT: I'm kind of full of crap here. If you're writing the Java code, you can call System.exit(whatever). But nonetheless, if your installer requires certain exit codes from any app--java or otherwise--you have a problem.

Fetch data from table and generate attachment than mail it.

Hello Experts,
From couple of day I am searching on Google for a better database procedure that will help me to get data from tables and generate attachment and mail it but i fail.
My Scenario is:
I have a query that will fetch almost 5000 records from database tables. Each record has almost 75 characters
select a.location_code,
               a.item_code,
               b.description item_desc,
               to_char(a.manufact_date,'ddMonyy')mfg,
               to_char((a.manufact_date + nvl(b.expiry_period,0)),'ddMonyy')expr,
               to_char((a.manufact_date + nvl(b.qurantine_period,0)),'ddMonyy')qrtn,
               round(nvl (b.qurantine_period, 0) - (sysdate - a.manufact_date)) days_elapsed,
               a.closing_balance_posted quantity
          from wms_stock_current_balance_v a, wms_item_setup_mast b
         where a.closing_balance > 0
           and a.item_code = b.item_code
           and a.loc_type in ('RACKING','PICKING','QUICKA','BUNDLED')
           and nvl(b.qurantine_period,0) > 0
           and round(nvl (b.qurantine_period, 0) - (sysdate - a.manufact_date)) <= 0
      order by a.item_code, a.location_code;
Sample data of above query is
LOCATION_CODE
ITEM_CODE
ITEM_DESC
MFG
Expiry
Quarantine
Days Elapse

Error while creating connection between Java and ABAP

Experts
I am getting the following error message when I am trying to test the connection between JAVA and ABAP systems.
1. The system ID is valid
2. The system was retrieved.
3. The system object represents an SAP system
4. The following parameters are valid: Web AS Protocol (http) Web AS Host Name (s09f71v06.svr.bankone.net:8100)
5. The host name s09f71v06.svr.bankone.net was resolved successfully.
6. The server s09f71v06.svr.bankone.net *could not be pinged* successfully.
I have JAVA and ABAP on the same system. I am trying to establish a connection. I have checked all the settings and they looks fine. I have also pinged from other system to this server and the Ping works fine.
Please do let m eknow where do I need to check for the errros or logs for the above error message.
Appreciate your quick help.
Mahesh

Check the relevant services are test are active on the Backend system through SICF trransaction.
Also make sure that default icm services are running.See note 517484.
More important the connector test in the portal system should work properly,recheck the WAS path etc are correct.

Updated to Access Connections 5.02 and location profiles disappeared

After updating Access Connections from 4.52 to 5.02 all the wireless location profiles are gone, including WEP keys, etc. The old version of AC worked fine on my X61S.
1) How can one upgrade to AC 5 without losing these?
2) I have complete system backups. In what file or registry entry can I find the saved location profiles from 4.52?

Same thing happened to me. Most frustrating...
I was able to find a listing of the now-missing profiles in "HKLM\SOFTWARE\Lenovo\Access Connections\Locations". Using regedit, I removed the following DWORD key, "m_bHideInList", from each entry and all of my location profiles now appear in Access Connections again as they were before. Looks like there also are a variety of other (rather straightforward) configuration parameters in the registry key(s) listed above, so hopefully something in there is the magic bullet.
Anyway, hope this helps.
C'mon Lenovo -- this seems to be sloppy coding, pure and simple. You're better than this!

As for Aperture, you'll need to do a search on the support website yourself because the result is a download so I couldn't post a link - the instructions are in the user manual. I believe the settings are within Aperture's Preferences.

Connecting from Office and Connecting from Remote

Hello
Can anyone tell me what is the difference between "Connecting from Office" and "Connecting from Remote" in the connection wizard ?
Thank you in advance

Hi Naldoo,
Into installation of SAP BPC you are specifying for application server 3 names:
Application Server Name
External Application Server Name
Virtual Name
The third one is used in case if you are using NLB.
The first one is the one using by "Connecting from Office"
The second one is used by "Connecting outside of office"
For this reason External name must be FQDN )Fully qualify name)
Application Server name can be short name
I hope this will help.
