Running forms web with java

Hello everybody.
Normally Im running Forms (10g) from Windows client using Firefox 2.0 with Jinitiator 1.3.1.22.
It is obsoleted I think.
My questions are 2.
There is any new version of Jinitiator that can be used with Window 7 or XP but with Firefox 3 or IE later versions?. If true please send me the link.
Also
Where I can find documentation to install the java to run Forms with latest IE.
Thanks in advanced and regards to all.

No versions of Oracle Jinitiator are supported on Vista, Win7, or any other newer MS OS. You must use the Sun JRE/JPI on these platforms. You did not mention which Forms version you are using so I will assume by "10g" you mean 10.1.2.x. Please refer to the following:
http://www.oracle.com/technetwork/middleware/ias/downloads/as-certification-r2-101202-095871.html#BABGCBHA
Be aware that in most cases, you must patch your Forms (or Application Server) installation to 10.1.2.3 if you have not already done so.

Crawling the Web with Java

Hi everyone.
I've been trying to learn how to make a web crawler in java following this detailed albeit old tutorial: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/
The SearchCrawler class they feature can be found in two parts:
First part: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/3/
Second part: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/4/
I don't want to copy and paste the code because it is really long and an eyesore if viewing here.
I get a lot of errors when compiling of which I do not understand. The majority of the errors (62 of them to be precise) are "class, interface or enum expected" errors, with the remaining few being "illegal start of type" and "<identifier> expected" errors.
Can someone here perhaps take a look at it and compile it and see if they also get the same errors? I realise it is an old tutorial but there are hardly any detailed resources I can find for java web crawlers.
Thanks.

Odd I can't seem to log into my account. Never mind.
I have used java before, the problem here I suppose is I'm not good enough to spot what's the problem. The code seems fine bracket wise and it has really left me stumped.
If someone code put it in their editor and attempt to compile and see if I'm not the only one that's having a problem.. that would be much appreciated.

Run Forms Web on Linux

Hi,
How do run Forms web (10g) on Linux Ubuntu 10.10 and Chrome or Firefox?
I search in Google but don't locate a ideal solution.
Thanks.

Do you mean does it run in a browser on Ubuntu or do you want to run the application server on Ubuntu ?

Error 18114 using Run Form Web button

Hi,
I'm using Forms 6i/Win XP on Oracle 9i. On attempting to run the form from inside Builder (Run Form Web button) the following error occurs: FRM-99999: Error 18114 occured, see release notes... I tried to solve reading this notes and searching for that error but I didn't find any useful. Someone can help?
Thank you
Massimo Nicosia
Rome, Italy

Ooops sorry, this error is VERY well documented in my release notes file. It's due to the registry string value FORMS60_JAVA not found on node HLM/Software/Oracle. Now it works.
bye
Massimo

SUBMIT(to SAP) Button in Adobe Interactive Forms (Web Dynpro Java)

Hi ,
I m using Adobe Interactive Forms with Web Dynpro Java
But submit to SAP button is not working
i m using NWDS 7.2 with adobe lifecycledesigner 6.0
with adobe reader 9.0
when i click submit to SAP button in interactive form nothing happens and
data is not transfered into web dynpro Context
Can anybody help me out................

Hi Adi,
The evniorment and versions you posted seems to be quite scattered, make sure all are of compatible and to the lates.
Anyways this was not the reason for your problem.
Can you tace if the button click event is triggered ....?
1) when the PDF is published can you see any of the fields editable...? reason behind is generally when you create a form in ADLC it comes up in static PDF format if its so you need to make it dynamic.
I dont know if adding the webdynpro script to your form might fix.
Regards,
Sai

Run Form Web

I got a problem when running a form in the appletviewer. When window of this form is maximized, still its title is visible on top of its own window. So I got two blue titlebars on the screen, one for the appletviewer and one for the active forms window.
Besides, is there a way to configurate running a web form from forms builder ? Seems like the Forms Server configuration does not work on this environment. I want to get rid of the splash screen and the appletviewers window title. According to some other threads this could be done by setting params in formsweb.cfg or the base.html but yet nothing worked.
Thanks in advance

assuming you use the JInitator turn its debugging Java console
on in the JInitator control panel (look for it in the start-
program menu).

Hi,
I am working on web services with 9iAS.
I am using the StatelessExample file included during installation.
The ear file was created and the application was deployed using OEM Web.
But when I try to execute the client java file StatelessClient. I get an error. The error is something about content type.
The error message is pasted below.
And also how do I run the web service on the browser.
Please help.

If you are getting this error, then you are most likely compiling your code with a different JVM than what is shipped with the application server. Oracle9iAS Release 2 (9.0.2) uses the JDK1.3.1. I got this error when I compiled the code with JDK1.4.0_01.

Error running forms 10g with OC4J

Hi everyone,
I installed Oracle DB 10g and Developer Suite 10g (did not install Ap. Server) at the same machine (different homes), everything seemed to be OK, I use sqlplus with no problems, then I did this:
1) Created a table with just one field
2) Created a test form with Forms 10g using wizard with just that table and that field (I connect to oracle with no problems on forms builder)
3) Started OC4J Instance
4) When I run the form, it opens Internet explorer then shows Oracle application server forms service, but with this message ORA-12560 TNS: Protocol Adapter error, I click OK and ask me for a user and password, but the same error!!
IS there any configuration that I have to do on OC4J?? Why I can connect to oracle from sqlplus, enterprise manager and so, but it fails running forms, specifically when open OC4J???
Thanks in advance

Did you save the form before running it, in the context of the builder? there is a known bug in this area.

How to run sscript shell with java program

Hi everybody,
i want to know how can i do to execute a script shelle (bash) with program java (if it s possible)
for example this script:
#!/bin/bash
echo "hello"
can i run it with java program or i have to make dome modifications .
thank you for your help in advance.

Well, if you want to be portable across platforms, you should write as much code in Java as possible and not rely on native scripts (I'm sure your script is more complex than this 'echo' example ;-) ).
Having said that, you can use the java.lang.Runtime class and in particular its various exec() methods.
Try something like this:
Process p;
try {
p = Runtime.getRuntime().exec("myscript.sh");
} catch (IOException ioe) {
}You can then "interact" with the spawned process with the Process object returned by the exec method.
Note you need to have the appropriate security rights.
For more details, look at the API documentation here:

How to run native program with Java program?

Hello
I've got following problem. I'd like to write file browser which would work for Linux and
Windows. Most of this program would be independent of the system but running programs not. How to run Linux program from Java program (or applet) and how to do it in Windows?.
Cheers

Try this:
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec("ls -l");
InputStream stream = proc.getInputStream();
InputStreamReader isr = new InputStreamReader(stream);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ( (line = br.readLine()) != null) .....
"if the program you launch produces output or expects input, ensure that you process the input and output streams" (http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html)

Forms 6i Run Form Web Preview Error

Help! Help! Help! Help! Help! Help! Help!
Nt 4.0, SP6A
Forms and Reports 6i (installed first, Home0)
Oracle 8i Client for database management
(installed 2nd, Home1)
Home selector selected for Home0
When running web preview I get the following error: FRM-99999: Error 18114 occurred. See the release notes file (relnotes) for information about this error.
Release notes suggestes the following
FRM-18114: FORMS60_JAVADIR not set.
Cause: For Web Preview from the Builder to work the Registry variable
ORMS60_JAVADIR must point to the location
that contains the Forms Java files. This
varable should have been set by the Oracle Installer when Oracle Forms Developer was installed. A typical value for this variable is c:\orant\forms60\java.
Action: Create or update the registry variable on NT, FORMS60_JAVADIR, and set its value to the location that contains the Forms Java files.
I created a registry entry in HKEY_LOCAL_MACHINE, SOFTWARE, HOME0 containing the following: FORMS60_JAVADIR:REG_EXPAND_SZ:C:\Oracle\Dev6i\Forms60\java
The error persists.
Has anyone experiences this problem or have
any ideas. Thanks in advance for help.

Theresa,
More than likely, you need to change the properties of the Forms Runtime (ifrun60.exe) to run in Windows XP mode and run with Administrator privileges. Since Oracle Forms 6i is so old it does not work very well with the new security model of Windows 7.
Hope this helps,
Craig B-)
If someone's response is helpful or correct, please mark it accordingly.

Headstart Designer generated form crashes with Java EOF error

When closing a form while in Enter Query mode, the form crashes & user is
disconnected from the database with error:
FRM-92100: Your connection to the server was interrupted.
Details:
Java Excepton
java.io.EOF Exception
at java.io.DataInputStream.readUnsignedByte(Unknown Source)
at oracle.forms.engine.Message.readDetails(Unknown Source)
at oracle.forms.netStreamMessageReader.run(Unknown Source)

Designer generates the ON-ERROR block level trigger. It has
execution style of BEFORE. Therefore, both the block level and
form level ON-ERROR triggers will fire.
Normally, in the block level trigger, Designer will generate
calls to its own message handling package to display any
constraint errors. However, Designer also allows you to specify
your own custom message handling package.
The package must contain:
- a procedure called PUSH
- a function called MSGGETTEXT, and
- a procedure called RAISE_FAILURE.
The preference MSGSFT, Package Used for Messaging, allows you to
record the name of the custom package.
Once you have recorded this in the preference, whenever you
generate a form, Designer will use your package and procedures
for its error handling code. That is why you see calls to
Headstart specific code in the block level ON-ERROR triggers.
If you want to customize the ON-ERROR triggers, you need to make
sure you understand how the MSGSFT preference is used. Read the
online help. Then, you can customize individual blocks by adding
application logic to the block, or you can add your own ON-ERROR
trigger to the object library in the CG$BLOCK object.
However, be warned that the Headstart error handling mechanism
depends on this code. Depending on what you do, you could end up
breaking things.

Run Form Web Button in Forms6.0

I see an option of running the forms on the Web. I assume this will show me the form as it will appear on the web. But when I run the forms with this option, nothing happens. Am I missing something ?
We are using Forms 6.0.5.31.0 (Oracle 8.0.6)

Thanks Jeet!
<BLOCKQUOTE>quote:<HR>Originally posted by Jeet Salian:
Read the release notes (relnotes) for this version,
Though this button is visible, it does not work and according to the great guys in Oracle it will be fixed in the next release.
