Oracle Form URL with content root's children directories path?

Hi All
In this case , we try to add children directories under default form path ( ex: Oracle_FRHome1/forms/DEPT_001/xx001_01.fmx and Oracle_FRHome1/forms/DEPT_002/xx002_01.fmx )
but there are so many children directories in our legacy systems, so it's not possible for us to add all path in server form_path variable
We try to call form directly in url
such as : http://localhost:9001/forms/frmservlet?form=/DEPT_001/xx001_01.fmx
first error appeared with such error message : FRM-92190: JavaScript is unable to evaluate expression.
After confirm error message, our form xx001_01.fmx still work fine
Are there any configuration file should be adjust in this case ?
Thanks~

Hi Tony
Thanks for your response.
In this case , we have to many difference directories in legacy system.
FORM_PATH must be under some maximum length restriction and may exceed max length in this scenario
Is is possible to change AliasMatch in forms.conf for url pattern matching ?
best regard
thanks

Calling web service from oracle forms fails with ORA_JAVA.JAVA_ERROR

Problem Description:
I'm following the steps as per the doc:
http://www.oracle.com/technology/products/forms/htdocs/10gr2/howto/webservicefromforms/ws_10_1_3_from_forms.html
to create a java stub to call external web service and then use java importer in oracle forms to call this web service from oracle forms.
WSDL for external web service used is http://www.webservicex.net/CurrencyConverter.asmx?wsdl
Calling the web service using JDeveloper works fine but from Oracle Forms returns ORA_JAVA.JAVA_ERROR; Unable to call out to Java, Invalid object type for argument 1
The code from oracle form to call web service is as below:
DECLARE
jo ora_java.jobject;
rv ora_java.jobject;
ex ora_java.jobject;
outString varchar2(2000);
BEGIN
jo:= CurrencyConvertorStub.new;
--This will get the exchange rate from US Dollars to UK Sterling.
rv:= CurrencyConvertorStub.ConversionRate(jo,'CAD','USD');
message (float_.floatValue(RV));
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
WHEN ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
outString := Exception_.toString(ex);
message(outString);
END;
Any help/ideas on this is greatly appreciated. Thanks.

Yes, it is the message line - so basically this call fails => rv:= CurrencyConvertorStub.ConversionRate(jo,'CAD','USD'); and control goes in the exception block
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
Below is the code from java stub that was generated using JDeveloper by using web services stub/skeleton and associating the WSDL
public Double ConversionRate(String FromCurrency, String ToCurrency) throws Exception
URL endpointURL = new URL(endpoint);
Envelope requestEnv = new Envelope();
Body requestBody = new Body();
Vector requestBodyEntries = new Vector();
String wrappingName = "ConversionRate";
String targetNamespace = "http://www.webserviceX.NET/";
Vector requestData = new Vector();
requestData.add(new Object[] {"FromCurrency", FromCurrency});
requestData.add(new Object[] {"ToCurrency", ToCurrency});
requestBodyEntries.addElement(toElement(wrappingName, targetNamespace, requestData));
requestBody.setBodyEntries(requestBodyEntries);
requestEnv.setBody(requestBody);
Message msg = new Message();
msg.setSOAPTransport(m_httpConnection);
msg.send(endpointURL, "http://www.webserviceX.NET/ConversionRate", requestEnv);
Envelope responseEnv = msg.receiveEnvelope();
Body responseBody = responseEnv.getBody();
Vector responseData = responseBody.getBodyEntries();
return (Double)fromElement((Element)responseData.elementAt(0), java.lang.Double.class);

How to connect oracle forms 10g with oracle 10g express database?

Hi all,
I have downloaded and installed oracle forms 10g and oracle database 10g express, when I open net configuration assistant to test local net service, I tested the default service (EXTPROC_CONNECTION_DATA) BUT THE RESULT IS "ora-28547 connection to server failed probable oracle net admin error"
How can I solve this issue?
My tnsname.ora is located in c:\DevSuiteHome\network\admin\tnsnames.ora, and its contents is:

I copied the contents of C:\oraclexe\app\oracle\product\10.2.0\server\NETWORK\ADMIN\tnsnames.ora and appended it to C:\DevSuiteHome\NETWORK\ADMIN\tnsnames.ora
and tried net configuration management to test local net service, the test was ok, thus the first problem resolved.
but the login problem in forms developer still exist and it claims that: ora-12154 tns could not resolve the connect identifier specified.
any ideas?

Connect Oracle Forms 6i with Sql server

Plz tell how to connect oracle Developer 6i with Microsoft Sql Server 2005.

thanksOracle Forms is best used against an Oracle database... so why on Earth would you want to use it against SQL Server?
Aside from that, Oracle Forms is old technology... you'd be better using Oracle Application Express (Apex) for producing web based apps.
If you must do things against an SQL Server database, you would need to set up heterogenous services connectivity (HS) and treat the SQL Server database as an external database.

Is it possible to use Oracle Forms 10g with Oracle 10g Lite Database?

Hi All,
We are in process of migrating our forms from 6i to 10g environment.
We have two kinds of applications, one set run on general Oracle 11g database and the other set of forms run at the client machine using Oracle lite database.
We dont have any problem with Forms 6i to connect to Lite database as it allows to connect through ODBC:DSN names. When we try to connect to a lite database (10gR3) from Forms 10g through ODBC/DSN, it's not allowing and throwing the below error.
ORA-03121 : no interface driver connected - function not performed
Can someone tell me if there is something wrong in our approach? Also advise how to use Oracle Lite database with Forms 10G.
Sincerely,
Praveen Manthena

Hi,
I have experience with 6i with lite database 10g. There are two version of lite database one is multi language support and other one in english. There lang problem in connectivity with multi language 10g lite database. I done connectivity with single language connectivity of 6i with 10g lite database. You should try this one with forms 10g.

Oracle forms authentication with active directory without OID

Hi Gurus,
I need to implement active directory authentication in oracle forms.
My scenario is this:
1. The user is created in active directory
2. The user is imported in our aplication, and then I assign the roles in Oracle, and create the user in my aplicattion.
When the user logs, the system have to validate the password with MS-AD. If the password is right, then, the system start a session in Oracle.
My questions are:
1. How can I validate the password in AD ? Is it in clear text, unix crypt, AES ?
2. In case the user has changed the password in AD, how can obtain he logs in oracle with the new password ?
We use oracle enterprise edition, but we don't have oracle applications, so i can't use identity management.
Thanks in advance for your help

You will need Oracle SSO and OID to implement Active Directory authentication for Oracle Forms. It comes with Oracle Application Server. You will need to read up on how to use AD instead of OID as the user store for Oracle Single Sign-on (SSO). Forms will use SSO to login not really knowing which user store is used so there is no config needed on the Forms side (except enabling SSO).

How Connect Oracle Forms 6 With Database 11g R2

Hello every one:
I'm Have application made by Forms 6 and Oracle 10g, now i'm make upgrade to my DB to 11G
but have problem when make connection between Forms 6 and 11g
ORA-02248: invalid option for ALTER SESSION
pls help me !!
Thnx

Oracle Forms 6i is not certified with Oracle RDBMS 11g and the last I read - there was no plans to certify Forms 6i with RDBMS 11g. If you search the Forums you can find some workarounds to make Forms 6i work with RDBMS 11g, but these are not Oracle Supported workarounds.
Your only real options are to leave things as they are or upgrade both your Forms application and the database. If you opt to upgrade your Forms application, you need to upgrade your Forms application to at least Forms 10g R2 (10.1.2.0.2) to be supported.

Integrating Oracle Forms 11g with JavaScript - keystrokes support issues

This article
http://www.oracle.com/webfolder/technetwork/tutorials/obe/forms/11g/jsinteg/formsjsinteg/setup.htm
shows the JavasriptIntegration with Oracle Forms.
I am trying to navigate out of Oracle Forms Java Applet with separateFrame=false to access an external menu using JavaScript. I can't find a way to navigate out of Oracle Forms. My focus stays inside the currently opened form and the applet does not lose the focus.
I need to access any external UI component by shifting the focus form the Java Applet to that components using only key strokes.
Thanks for your help

Vikas,
Sorry for the delay. I am still investigating this. In general, it would appear as I mentioned. If the form that contains the code specific to the event monitoring has not been run, then it cannot be executed. We are trying to get clarification on the definition of "scope" in this case. In the mean time, one alternative might be to subclass the related triggers/pu and include them in all of the forms where you want them to fire. Currently I am suspecting that scope refers to a relationship to forms currently running. For example if you have form A, B, and C running a scope of "form" might suggest that the events are only monitored if the current form includes the necessary code. However, if "application" then even if the form containing the necessary code is not the current form, the necessary code would fire anyway. Again, I am trying to get more clarification, but it is slow coming.
If this is truely an urgent issue, I encourage you to create a Service Request with Oracle Support.

I have a machine which does not have Mozilla. But i wanna run the forms in Google Chrome, not IE. I installed JInitiator (the final version), but when i run the form i still got in Chrome that there are missing plugins.
I should mention that i just installed Dev Suite 10gR2 and i did not change anything in forms configuration files.
What should i change and where?

Attach Forms With Comm Port in Oracle Forms

I am trying to make connection of Oracle forms Builder with my device using comm port but i dnt know the complete procedure to attach the comm with oracle forms also i have no idea to convert asquii data to normal form.Please any one help me to attach comm port with my oracle forms and also convert asqui code which is showing on hyper terminal into normal data.Also I am using oracle forms 6i

Make a java component (PJC) and use a rxtx library (http://rxtx.qbang.org/wiki/index.php/Examples) ...
I have made a PJC to use a RS232 port from oracle forms for Hypercom POS terminal..
Here is my code (in short i will post a component on PJC site (here I can't post a complete code because of 30000 char limit ;) )..
If you look in method "public void init(IHandler handler) " I make a download of rxtxSerial.dll from my forms server and then I call System.loadLibrary("rxtxSerial");"
In other way you must put the dll in windows/system32 path.. This dll is native library for rs232 communication.
If you look at the method "public void doTransaction" you can see the initialization of comm port...
With inputStream and OutputStream you read and write datas to/from your rs232 port..
p.s: the code is not complete but you can see how I made the rs232 communication (also the code is not final ;) )
