Importing the class in Oracle Rules Author Definitions

I created the Dictionary in the Oracle Rules Author.
In the Definitions Page I selected the java fact type.
In the User Classpath i gave the class path of the files.
Then i have to import my class in the Rules Repository.
I am getting the following error.
Cannot perform operation. RUL-01527: Received exception for loadClass. RUL-01016: Cannot load Java class example3.Retiree. Please make sure the class and all its dependent classes are either in the class path, or user specified path. Root Cause: example3/Retiree (Unsupported major.minor version 49.0)
Can any one respond to this query please...

You have to do like the others import. You have to put import and the complete path(with all the packages).
For example:
import mypackage.msgsend;
and if you wouls like to import all the classes of a package use:
import mypackage.*;

Error while importing java class into oracle forms 10g

Hi
I have generated a web service client using jdeveloper 10g. It consists of complex type methods. I am trying to import the class files using java importer in oracle form 10g. I am able import all of them successfully except one. That one is the main method. Please see the error and suggest me how to overcome this error.
Exception occurred: java.lang.NoClassDefFoundError: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
Thanks in advance

Do you see oracle/jdeveloper listed in "Import Java Classes" when you try to import?
If not, make sure you add C:\DevSuiteHome_1\jdev\lib\jdev.jar to FORMS_BUILDER_CLASSPATH in registry
Also excetion indicates: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
If you typing it - type: oracle.jdeveloper.webservices.runtime.WrappedDocLiteralStub

Import the classes in the package java.util

I haven't taken a class in two years so I have ideas but am unsure of myself, and I most likely am way off base, but is this how you import the classes in the package java.util
import java.util.*;
I would appreciate anyone's help. I have a lot of questions.
Thanks,
rp

My assignment is below so that you will know exactly what I am asking. I am being asked to create an instance of LinkedList. I know that this is a part of the java.util. So when you create an instance of LinkedList would that be similar to instance variables? or am I misunderstanding something. I have several ideas, so I will start with the first one.
LinkList();
I really appreciate your taking the time to answer my questions to help me to rebuild my confidence in doing this.
Thanks,

Oracle Rule Author(Oracle Business Rules)

Hi,
Iam implementing Oracle Business Rules, while configuring rules with Rule Author, a problem is faced, a variable data which is set in one rule's action is not available to next rule's condition.
i.e a variable set in one rule can not be used in other rule as condition.
Is there any option to make it work,
thanks & regards.

I think you would get better response on the question if you post the same question to the SOA Suite forum (SOA Suite

Oracle Rule Author admin pages not showing up

I installed the Oracle, Oracle application server and Oracle SOA Suite and was going through the SOA Order booking application but am currently stuck on the Rule Author. I bring up the admin page:
http://localhost:8888/ruleauthor
I log in and it displays a blank page.
Anyone have an idea what is going on?

I haven't seen this before. Could you provide some details on what options you installed SOA with and what browser you are using?

Getting error while importing the application in Oracle Apex

Hi,
I am facing an issue while importing an application into my new Oracle Apex installation. Installation was successful with out any issue. I exported an application from my old Apex (version 3.0.0.00.20) and importing the same into new apex (version 3.0.1.00.08). I am getting the following error.
============================================================
The requested URL /pls/apex/wwv_flow.accept was not found on this server.
============================================================
When I click on import in Application Builder page and then browse the required file it gives the progress saying "Importing File" and after some time it displays the above error.
I tried bouncing the application also and there is not error in alert log.
Could any one please suggest, if there is some problem here. Or my approach is not correct.
Thanks in advance.
Regards,
Advait Deo

Osacar, I recommend that you try to import the application into your workspace on apex.oracle.com and see what happens. Also, refine the problem statement as much as you can, e.g., you get this error importing "the application" or when importing "any" application. How big is the file you're trying to import? Where did it come from? Can you upload images?

How to import the classes?

Hai to all,
May I know how to import the packages in j2me that are not in the midpapi classes.
If I had some new package and I want to import that to my application
For example .
The javax.mail package is with me but I don't know how can I import it to my application.How to set a classpath to it.
(I set a classpath so that the j2me is not accepting the package but j2se is accepting is ther a special way to set a classpath to those package and where to keep those packages i.e in which folder ...)
Awaiting for the answers ..
Thanks to you

for sms check i.e. http://www.simplewire.com/. i know that there were some more companies but can't recall their names now :(
for encryption: i'd use midp 2.0 and rms, let user write their message, store it encrypted on rms and then send using some sms api. but that's just me ;)

Hi,
it is not astonishing that the error occurs every time you try this create table statement.
A table with this name already exists. And error -955 tells us exactly this.
What to do?
As I do not know if there is data in this table and/or if there are views / other database objects
using this table, I cannot decide, if dropping this table would be a good idea.
But what I do not understand is, why during one (?) loading in a clean (?) database this
table is tried to create more than once. Or was the database you are loading into not clean,
fresh and empty? Then it will happen that not only this table, but some others will result in an error
because they exist already.

How Can I import the comments to Oracle Tables?

Hi
I need to import several tables, this tables have several fields and in the database we have all fields with comments. I need to see this coments in the description of the logical and presentation tables. is this possible?
Thanks
Edwin

As far as i know, it is not possible since no there can be multiple row comments in your database. Maybe others can comment here if they have a solution.

How to import a Java class using Rule Author ?

I want to recreate the following ruleset using the Oracle Rule author
RL> ruleset parse {
import java.lang.Integer;
rule A {
String total = "12";
int t = Integer.parseInt(total);
if (t == 12) {
println("Total=" + t);
Does anyone know how to create the RL line "import java.lang.Integer;" using Rule Author ?

The line "import java.lang.Integer" isn't necessary if you fully qualify the reference to Integer.

Is it possible to use List Type in XML schema within the SOA Rule author?

Is it possible to use List Type in XML schema within the SOA Suite Rule author? The reason is that with the following XSD, Rule author generates XML facts of type "List" for the element "ResultSet". Basically I want to check the Input facts (Input1, Input2, Input3) for some conditions and then assign action to the element Resultset of type List (array). The output Resultset can contain multiple values based on the input facts. My problem is that I am unable to see the ResultSet in the "Assign" action type of the action block. Is it possible to use the Resultset of type List with the Rule author or is there any limitation on the rule author and any workaround for this?

Hi Richard,
I have slightly modified the xml schema you suggested and was able to import into the rule author. the following is the modified XSD. Rule Author created a List type for the "ResultSet" . I still don't see "Resultset" in the assign action, so I tried creating RL function in order to assign the output to the "Resultset", but was unsuccessful so far. can you please let me know how to populate the resultset with the output values? Thanks a lot.

Forms 10.1.2 - Imported Java Classes are not running on JNI.NEW_OBJECT call

Hi All,
I've created a java class to call a webservice. This has been developed and tested in JDeveloper and works ok (using JDev Wizards - so it's generated code). I've created the JAR from it, imported the classes into Forms Builder and have my package and imported the java exception_ class too.
So, everything compiles and looks good. When I run the application I can see in the console that my JAR is included in the loaded list. When I call the class (basing my code on the Forms Webservice example here on OTN) it doesn't work. I get the error ORA-6503 - function returns no value.
I can step through the code in debug and it's in the generated constructor "new" function when the JNI.NEW_OBJECT is executed. I can't see into that so I'm a bit stuck ... I don't whether it's my java that is now failing or the system is failing to call it :
FUNCTION new(
    a0    VARCHAR2) RETURN ORA_JAVA.JOBJECT IS
BEGIN
    args := JNI.CREATE_ARG_LIST(1);
    JNI.ADD_STRING_ARG(args, a0);
    RETURN (JNI.NEW_OBJECT('oracle/forms/atrium/wsexport/proxy/AtriumExportWSSoapHttpPortClient', '(Ljava/lang/String;)V', args));
END;Has anyone any experience or pointers for me ?
Are there any extra JAR files I need to include in the CLASSPATH ?
Forms Builder is 10.1.2.0.2, the Application Server is 10.1.2.3 and it JDeveloper 10 compiling Java 1.4. All on a Windows platform.
TIA
Steve

Not sure if this is exact the document you are searching for, but this one works for me:
http://www.oracle.com/technetwork/developer-tools/forms/webservices-forms-11g-094111.html
It's for 11g, but I don't think there is much difference to 10g.
Did you add your Jar file also to the classpath in the environment file of your webconfig?
cheers

Importing WebService class into Forms10g

Hi ,
I want to import webservice from Jdeveloper in Forms10g.I am using Jdeveloper 10.1.3.4 complaint with JDK 1.4. When I import the class in Forms10g from Jdeveloper it gave me error:
Importing Class Proxy.classes.oracle.srtutorial.datamodel.proxy.SendServiceSoapClient...
Exception occurred: java.lang.UnsupportedClassVersionError: Proxy/classes/oracle/srtutorial/datamodel/proxy/SendServiceSoapClient (Unsupported major.minor version 49.0)
I figured out that this error is due to different versions of JDK used in Oracle Forms10g(JDK 1.3) and Jdeveloper 10.1.3.4(JDK 1.4). So I changed the compile properties in Jdev to 1.3.
After changing this to 1.3 when I import the class the previous error is resolved but I get another error :
Importing Class Proxy.classes.oracle.srtutorial.datamodel.proxy.SendServiceSoapClient...
Exception occurred: java.lang.NoClassDefFoundError: Proxy/classes/oracle/srtutorial/datamodel/proxy/SendServiceSoapClient (wrong name: oracle/srtutorial/datamodel/proxy/SendServiceSoapClient)
Please help how to resolve this.

Noman

Hi,
I have tried. The problem is when I make the JAR file in Jdeveloper and Change the class path in Windows. The Jar doesnt shows up in Formgs10g when we import the class. I have tried several times by adding the path of JAR file in windows environment but still it doesnt shows up..

Where are classes for oracle.xml.parser.v2?

I have downloaded both V1 and V2 of the XML parser. I have managed to download the java classes under org.w3c.dom from www.w3.org but I can't find the classes under oracle.xml.parser.v2 (or without v2) anyway on technet. Both are required for import.
I would have expected them to be in the ZIP files xmlparser_v1_0_2_0.zip and xmlparser_v2_0_2_7.zip but they don't seem to be. These contain the equivalent HTML files but not the class files themselves, so compiling the samples is not possible.
Any help would be appreciated as this is becoming very frustrating.
Thanks in advance
Gary

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Steve Muench ([email protected]):

Many thanks Steve - yes unzipping the jar file corrects problem.
