Invoking Java classes from Forms

We are running an AIX Forms server, and we would like to be able to execute a java class with two command-line parameters (ex. "java myClass.class param1 param2"). Is the "java" run-time executable available on AIX? I'm assuming it would be part of the JRE installed with Oracle 8.1.6, but where might I find it, and can it be called with the HOST() command?
Thanks,
Jonathan

I think if you have forms server installed you will have a java runtime there on the disk somewhere.
Regarding activating the java check out the "java importer" tool that comes with patch 4 of developer 6i.

How to call Java class from Forms 6i?

Hi friends,
I need to call a Java class from my Forms 6i application.
(It runs under WIndows XP. It's a client/server application and I have only the client and the Form builder installed on my PC)
I don't know almost anything about Java's world so your help would be very useful for me.
Could you tell me exactly what i have to do?
I've read in metalink several Notes, but they supposed that the Java architecture is already installed in the computer.... I only have the default installation of Developer 6i... so I would need to know:
- How to install/configure the neccesary to execute Java classes without problem
- How to invoke the .class from Forms 6i.
Thanks a lot
Jose.

And also this one:
Problem Description
Installed Forms 6i Rel 2 on a MS Windows machine. When trying to Import the Java
Classes getting the errors
PDE-UJI0001 Failed to create the JVM
Solution Description
You need to to install JDK 1.2.2 to run the Java Importer. And set the PATH's
and classpath's correctly.
Explanation
1. Download and install the JDK 1.2.2.
Possibly available at: http://java.sun.com/products/archive/
2. Assuming the JDK 1.2.2 is installed in c:\jdk1.2.2 directory and the JRE in
C:\PROGRA~1\JAVASOFT\JRE\1.2 directory; ORACLE_HOME=C:\Dev6iR2.
Set the PATH to
set PATH=c:\jdk1.2.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin\classic;%PATH%
( If you are using ias9i then the JDK 1.2.2 comes with the ias installtion ,
in this case please set the PATH to
D:\ias9i\Apache\jdk\bin;D:\ias9i\Apache\jdk\jre\bin;D:\ias9i\Apache\jdk\jre\bin\classic;%PATH% )
3. Set the CLASSPATH to set CLASSPATH=%CLASSPATH%;C:\Dev6iR2\TOOLS\COMMON60\JAVA\IMPORTER.JAR;.
(If you do not set the CLASSPATH correctly you will get the error
PDE-UJI002 Unable to find the required java importer classes)
4. Now run the Forms Builder by using the command.
C:\Dev6iR2\bin\ifbld60.exe
Now the Java Importer Should Run fine.

Accessing Java Classes from Forms

Is is possible to access a Java class from Forms? I have been
creating an Active X control that returns a Java object, and from
that I can call methods on that object, but I would really like
to do that without having and Active X control in the mix. Any
suggestions?

Error Invoking Java class from Stored proc

We are getting this error while calling a stored procedure that invokes a
static function of a java class from inside Oracle 8.1.7.
ORA-29516: Aurora assertion failure: Java thread deadlock detected
ORA-06512: at "APPS.SERVICECONSUMERINVOKE", line 0
ORA-06512: at line 40
In a Toad SQL Window, when I execute the stored procedure that invokes the
java function, it executes successfully on the first attempt. When I try to
execute it again on the same SQL Window, it gives the above error. The java
class is part of a package and indirectly makes a JMS request-reply call
via other helper classes.
The same package works fine from other web containers and
unlike the Oracle JVM Aurora, the JVMs don't detect a deadlock.
Why does the Aurora throw an error?

Did you try issusing a commit and then trying again in Toad SQL Window?
The advice is to contact support:
ORA-29516: Aurora assertion failure: string
Cause: An internal error occurred in the Aurora module.
Action: Contact Oracle Worldwide Support.

No Class Found Error on invoking java class from PL/SQL

Hi There,
I have followed instructions on how to create a java proc in the DB to invoke it from PL/SQL.
I get a 'java.lang.NoClassDefFoundError' error because it cannot access 'org.apache.axis.description.TypeDesc' in this case. The instuctions say to add the supporting jars which contain the additional classes to the project's Additional Classpath's which I have done.
I deploy the java classes and create the java stored proc using JDev.
Can someone please tell me how to go about resolving this?
I can see 'org.apache.axis.description.TypeDesc' in the DB via JDev's Databse connection in the Java Classes tree?
Thanks,
Anthony

How to invoke Java class from post.POST.jsp

Hi All,
I am trying to invoke a simple java method from post.POST.jsp
I am getting below exception while doing it.
org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.jsp.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 32 in the jsp file: /apps/mywebsite/components/customFormAction/post.POST.jsp
The method test() is undefined for the type DatasourceUtil
29:
30:           ///
31:          com.day.test.datasource.DatasourceUtil dsUtil = new com.day.test.datasource.DatasourceUtilImpl();
32:          dsUtil.test();
33:           //dsUtil.validateLogin(request.getParameter("username"), request.getParameter("password"));
34:
35:           ////
It appears to resolve the class correctly. I could run the code, if I only comment dsUtil.test();. As soon as I uncomment, it gives above error.
In the Utill I have a simple void method which will print a simple text. My package structure is as follows.
any help will be great
Tx

1. In the interface [1] not the implementation[2] have u defined the method test?
2. If it is implemented, Change the bundle version in bnd file and make a new build. Then from felix console verify the latest version reflected in the bundles.
If 2 works & you are going to make lot of frequent changes then give the version as snapshot till it get stable.

Calling Java Classes from Forms 6.0

Can this be done?
How can it be done?
And, I don't mean JavaBeans... I don't want to embed a control
on my form... I want to call a standard java class routine.
Any help or laughter would be appreciated...
Thanks,

You have to write a wrapper classes so forms can call your java,
if you've got any yet.
Then use the Bean Area tool to draw the area your applet will
display in (if you don't want to display anything then don't
display anything in you java).
Its not really JavaBeans more like oracleBeans.
I've had to re-write functionality for the web such as
displaying open/save file dialogs.
If your interested and you've installed dev60, the example:
C:\orant\FORMS60
\java\oracle\forms\DEMOS\SOURCE\ProgressBarPJC.java and
ProgressBar.java got me started with alot of reading from
http://java.sun.com/products/jdk/1.1/docs.html

Is it possible to invoke a Java class from Data Services 4.0?

Is it possible to invoke a Java class from Data Services? I have a query transform with a varchar column which I want to run an external java class against to encrypt the string value. In the Management Console, I created an adapter of type TestAdapter and referenced my jar file in the Classpath section, but when I create a Datastore of type Adapter I can't import any functions related to my java class? It seems like I need to create a new Adapter type similar to the TestAdapter with the 'Adapter Class' set to my java class? I can't figure out how to do this - which is the correct approach and is there some documentation available? thanks!

First u nees to imoprt the class which u are doing right
then u need to call the function of the class , and then you can put the value in a string .
DbCon.function()
String data = DbCon.db;
where db is a string in DbCon
Cheers

Calling a Java Class from PL/SQL

Hai,
I need a technique of calling a class file and invoke its
methods written in Java by PL/SQL for my intranet development.
PLease let me know if you have really experienced and won.
Thanks
JOhnson

First, to call a Java class from PL/SQL the class needs to be
deployed to the database. you can check the 8i documentation for
the instructions for loading Java into the database(LoadJava).
The document contains information on how to load the Java and
call it from PL/SQL. The following links should help.

I want to call External Java class from the PL/SQL

Hi,
I am using Oracle Apps R11i (11.5.7), I wanted to call external Java class from the PL/SQL. This external Java class is residing in another application server.
How do I do this.
I know one way. Develop C routine in Oracle Apps to call external java class and call this C routine from the PL/SQL.
Is there any simple method available? or any other method?
Thanks in advance.
-Venkat

First of all, this is a Java application you're talking about, right (i.e. it has a main() function)? It's not just a class that you're trying to instantiate is it? If it's an application, you obviously have to start a new virtual machine to run it (rather than using the virtual machine built into the database like stored java). I'm a little leary of your mention of an "application server" as this would more commonly mean that a virtual machine is already over there running with access to this class. In which case, you'd typically interface with SOAP or some other RPC API.
All that aside, as long as you have physical disc access (through NFS or whatever) to the class file, you could use a java wrapper class with a system call to do this. In fact, there is a thread in just the last day or so on this very forum that has the code to do just that (see " Invoking OS Commands from PL/SQL"). However, it's worth noting that the virtual machine will be running on the database server in this case and not the application server.
