Applet Parameter Reference

Excuse the stupid question, but does anyone know of a list describing the various parameters that can be passed to the forms applet at runtime? Among other things, I'm looking for one that lets me change the icon and title of the window that forms display in when I run with separateframe=true.
Thanks,
Alex Valys

Looks like you are going to have to sign your applet.
It looks as if that ORB object is trying to modify something with threading that the default Security Manager in Applets won't permit to happen.
To be honest I am more than a little suspicious of code that feels it needs to fiddle with thread things but whatever. You are going to have to sign and your applet
and get the permission you need for the ORB to do it's thing.
If you have more questions about this you should post them into the [_Signed Applet Forum_|http://forum.java.sun.com/forum.jspa?forumID=63]

Is it possible to create a bean that will generate (fill up) applet paramet

Hi all,
As a newbie I was asking myself is it possible to create a bean that will fill up applet parameter or directly generate the applet ??
And I can I create it ?
I mean : Having a jsp page that make reference to the bean, the bean shall generatehtml applet parameter values.
Some samples will be welcome or a template.
Thanks in advance
Shamann

Thanks a lot for your reply siv viv,
I've posted this thread because I'm a little bit disappointed with Applet and jsp according to lot of thread about this subject (it seems that communication between applet and jsp is not easy : bug reported).
The basic thing i want to do is to create a dynamic Pie Chart as applet or bean so i need to set applet parameter thanks to variables.
See the http://forums.java.sun.com/thread.jsp?forum=45&thread=80250 this one is putting me in the dark.

Does BOXI support crystal reports with parameter references in formulas?

I am designing a report in Crystal Reports XI Developer that contains parameters, which are passed to a stored procedure and are also used within formulas ( in Crystal Syntax ie. {?FORMAT_ID} ) in the report itself.
I can run the report successfully in CRXI Developer. The formulas use the correct values from the parameters entered during execution and everything looks good.
I then deploy the report to Business Objects Enterprise XI. I do all of the things necessary to manage the report including setting up the proper database connection information and default parameter values.
When I run the report using the Crystal Report Viewer, I get the following error message:
Error in File Forecasting.rpt:
Error in formula <Report Format>.
'if (not isNull({?FORMAT_ID} ) ) then
This field name is not known.
Details: errorKind
This happens when I press the "Preview" button in the Manage Object dialog from Crystal or when I run the report using InfoView.
I have changed the formulas and it doesn't seem to matter what the specific content of the formula is; other than the existence of a parameter reference in the formula. If I comment out the parameter and replace it with a hard-coded value, it gets through the formula fine.
Does Business Objects Enterprise XI support crystal reports with parameter references in the formulas?
Thanks,
Tim H.

Hi,
In Crystal Reports under File -> Report Options >check convert Null Values to default > Verify on first refresh > Verify stored procedures on first refresh.
This corrected the issue by allowing the query engine time to locate those columns and map them to the query being sent by the report.
The convert null values was added because those field were being used in the record selection and grouping.

Forms applet parameter

Forms applet parameter colorScheme=teal
how much color scheme can we add in parameter.

You can see here on documentation:
http://download.oracle.com/docs/cd/B19375_07/doc/frs/forms/B14032_03/toc.htm
You must check in section 4.3.4.4 Applet or Object Parameter
Hope it helps you,

<PARAM NAME="Applet:CODE" VALUE="opis/opis.class">
</APPLET>
I want to pass "level" parameter to Java program using:
<PARAM NAME="level" VALUE=" ????? ">
How should I reference "level value" within VALUE=""
Thanks.

I am also looking for a solution, can someone help ?

Analyzer applet parameter useFrame error

Hi all, I've the problem of customizing the deployment ofanalyzer 7.2 reports by opening them in a frame of an externalwebapp.I was able to open the analyzer.jsp in the frame, but then theanalyzer applet is opened in another window.Is it possible to solve my problem (without using the analyzerhtml version)? Thanks in advance for your help. Giovanni

I've forgot to say that I've found the UseFrame appletparameters that seemed to do what I wanted, but trying to use it,an error of unsupported parameter or method is raised.Have someone used this parameter, and has it the meaning to makethe applet load within a frame? Thanks againGiovanni

Applet parameter list

can any one send all possible parameter for java applet to deploy form on web.

Could you explain a little more about what you want the new parameter to achieve? I'm not sure what you mean by 'refresh parameter'..?
You'll find a useful explanation of the possible parameters in formsweb.cfg at http://www.huihoo.com/oracle/docs/B14099_19/web.1012/b14032/configure003.htm#i1072143, if that helps.

Applet parameter

Hi all
Do you have any idea to set up a parameter inside an Applet rather than inside an html code?

Not sure about your question, try this [url http://java.sun.com/docs/books/tutorial/applet/appletsonly/param.html] Defining and Using Applet Parameters

Custom report parameter references

Dear All,
I have a custom report with two parameters
FROM_PRAM
TO_PRAM
Both parameters have same SET_OF_VALUES.
I want to apply check on parameter level that TO_PRAM value should not less than FROM_PRAM.

You can check that in the after-parameter-form trigger.
if :to_pram < :from_pram then
srw.message(100, 'TO_PRAM value should not less than FROM_PRAM');
return false;
end if;

Can't use parameter reference from DLL C on pl/sql

hi all, I have dll(newStr.dll) write by c language with a function name is "strNew", following code in c and pl/sql:
char* strNew(char *& str){
     if (str != NULL){
          str = strdup("");
          str = strcat(str,"String is not null.");
     }else{
          str = strdup("");
          str = strcat(str,"String is null.");
     return str;
On PL/SQL I call the dll(newStr.dll), following code on pl/sql:
1) Create library:
     CREATE OR REPLACE LIBRARY TestDLL AS 'D:\newStr.dll';
2) Create package:
     CREATE OR REPLACE
     PACKAGE TEST_DLL AS
     FUNCTION strNew(str IN OUT varchar2) RETURN VARCHAR2;
     END TEST_DLL
     CREATE OR REPLACE
     PACKAGE BODY TEST_DLL AS
     FUNCTION strNew(str IN OUT VARCHAR2)
     RETURN VARCHAR2 AS
     EXTERNAL LIBRARY TestDLL
     NAME "strNew"
     LANGUAGE C
     CALLING STANDARD PASCAL
     PARAMETERS(str BY REFERENCE STRING, return STRING);
END TEST_DLL
3) Create Procedure:
CREATE OR REPLACE
PROCEDURE TESTPRO AS
newStrIn varchar2(40) :='test';
newStrOut varchar2(256);
BEGIN
newStrOut := TEST.strNew(newStrIn);
DBMS_OUTPUT.PUT_LINE('newStrOut = ' || newStrOut );
DBMS_OUTPUT.PUT_LINE('newStrIn = ' || newStrIn );
END TESTPRO;
4) Run procedure the result following:
newStrOut = String is not null.(it correct)
newStrIn= 8!(it wrong, the newStrIn='String is not null' is correct))
I not found root cause why in pl/sql, I can't get the variable reference from dll c.
Please help me.

For compatibility purposes you would probably be better using 10g development rather than 9i if you are going to use a 10g database. I'm not familiar with the latest versions in terms of Oracle Forms, cos I stopped developing in Forms back on version 8.
Essentially there are different components you can download and install.
Database - This sets up a database server and allows you to create databases to store your data in.
Client - This installs the necessary client software to allow you to connect to a database on a database server. It includes client software such as SQL*Plus and the drivers needed to make the connections.
Developer - This is a client side development environment for developing forms and reports. It requires the Client software in order to be able to connect to the database.
By the sounds of it you have downloaded and installed the last two, but without the first one you don't have a database to connect to.

How to set applet parameter in java code?

Hi All,
Instead of setting applet parameters in JSP page, Now I have a need to set
applet parameters in java code. But I can't find a method that allow me to do this. There
is only getParameter but seems no setParameter method.
Any help is appreaciated.
Thanks,
Chris

Take a look at set_custom_property:
public static final ID SETTEXT = ID.registerProperty("SETTEXT");
public boolean setProperty(ID pid, Object value)
if (pid == SETTEXT)
String text = value.toString();
and in forms
set_custom_property('beans.bean_item', 1, 'SETTEXT', 'some text');
cheers

Javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

Reference to the main Applet

Hi,
how can I give another applet a reference to me at a function call.
The "this" variable only gives a reference to the sending component, but I want to give a function a reference to "Applet" itself, so that the other applet can call functions from "me" like "firstapp.setvalue(1)".
Thanks a lot

Opening/closing References in TS-engine does not work as expected, so creating memory hooks. Any solutions?

Hi!
As my project had grown beyond the point where I could keep a global overview, I tried creating atool that dynamically creates a kind of hirarchy for my TS libraries. It runs quite well for a small test setup, but crashes due to missing memory for the whole project. Any ideas?
A short description: I do all coding in LV7.1.
* Firts I open an automation refnum to TS.Iengine and invoke the method 'GetSequenceFileEx' with the path to my main seqfile, Flags = 0 and conflicthandler_Error.
* Than I use that sequencefile object to invoke the method 'Getsequence' with an index of 0 (assuming this beeing the 'MainSequence').
* For the returned sequence object I invoke the method 'GetNumSTep', which is fed into a For-Loop. Inside that loop, the very same object reference is used to:
- invoke 'GetStep' with the loop index
- with the step object i get some proiperties like Name, some expression and bolean values. If the step 'can_Specify_module', I invoke 'GetDescriptionEx', before the step object is closed (cvlose reference vi)
- I also invoke 'Parameters' on the step object. The parameter reference is used to access the property 'getLocation', which than is used as lookupString to access the property 'GetNumSubProperties', which I take as number of parameters of that step. Finally the parameters reference is closed
* The reference to the sequence object is closed after the for loop.
I fianlly get an array of description for all steps in the sequence file, in the order they are called from mainsequence there.
This array is used to recursively add a similar subarray for any subsequence call in it, until all calls are resolved (using a while loop that runs until the loop counter reaches the number of steps in the step description array).
The array is than scanned for 'typical' errors of mine like wrong parameter number at subsequence calls, missing/misspelled subsequences andf so on.
The LabVIEW execution accumulates more than 1 GB of RAM. LabVIEW itself reports just some 100kB of used RAM. So I assume the difference is RAM used by TS as a child process in LV. What can be done?
A vi with this code is provided (AS IS!).

Hello Lul,
I tried out you tool and took a quick look at it and it ran fine. I did notice that LV memory grows during execution but only a few kb with a standard demo from TS (the increase is about the same size as the file being saved at the end). This is expected bahavior since results are being stored in memory during execution. When it is done, my mem goes back to about what it used to be before running. 1 GB of Mem seems to be very very very high! Did you expect it to be like this? How big is your txt file being created? Is the VI you posted exactly what you are using or do you have additinal loops that make the VI run continuosly and save to txt after multiple runs? I did not see any critical issues with your VI but I also did not go into your code in debth.
As long as you close all your TS references in LV, you should not havbe any mem leaks.
If you expect big fiole to be created, your PC will use up all RAm then use Virtual mem, the size for Virtual mem can be set in the Control Panel in Windows, usually tough, the system can set it dinamically, this might help you avoid crashe.
Hope this helps
Nick
