Evaluting BODMAS expression using a Java Class

Hi,
How to evaluate an BODMAS rule in java class. I will be getting some formula and i should evaluate using bodmas rule. Can any help me out in this.

And taking some notice of the reply that was provided three times, instead of just repeating the question, also doesn't cost a thing. Some people think it is the entire point of the forum, and of posting in the first place.
And reviving old threads just to tell someone that they need 'a lot of growing up', and to improve their 'manners', and to stop the 'hostility and nastiness', while claiming you're 'not trying to start a fight at all', is not at all convincing. In fact it is both childish and ill-mannered.

AES Algorithm error when trying to encrypt using stored Java class.

Dear All,
We have a specific reuirement where in we cannot use DBMS_CRYPTO package to encrypt/decrypt data using AES Algorithm
So I am trying to use a stored Java class and I am getting "AES algorithm not available".
I am using Oracle 10gR2 standard edition.
Below is my code
1. Stored Java class
2. Stored function to access the above Java class.
3. Test anonymus PL/SQL to test above code.
Please help me finding the problem why I am getting "AES algorithm not available" error when I call stored Java class in Oracle.?
**** If I use "DES" algorithm, it works. Also the Java code works well if I execute it as normal Java class from Eclipse.
I verified the java.security file in jre/lib/security and I see that there is provider entry for SunJCE.
The jre version in Oracle is 1.4.2.
I appreciate your help.
Thanks,
Priyanka
Step1: Stored java class to encrypt and decrypt data
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "EncryptUtil" AS
import java.security.Key;
import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
public class EncryptUtil
     public static String encrypt(String inStr)
     String outStr = "Test data 123";
try
KeyGenerator kgen = KeyGenerator.getInstance("AES");
kgen.init(128);
SecretKey skey = kgen.generateKey();
byte[] raw = skey.getEncoded();
SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
Cipher cipher = Cipher.getInstance("AES");
cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
byte[] encrypted =
cipher.doFinal(inStr.getBytes());
outStr =new String(encrypted);
catch (Exception e)
     outStr = outStr + "exception thrown::" + e.getMessage();
e.printStackTrace();
return outStr;
Step2: Stored function to access above stored java class.
CREATE OR REPLACE FUNCTION SF_ENCRYPTUTIL(
pKey1 VARCHAR2
) RETURN VARCHAR2 AS
LANGUAGE JAVA NAME 'EncryptUtil.encrypt(java.lang.String ) return java.lang.String';
Step3: Test encryption and descryption
DECLARE
outstr VARCHAR2(2000);
BEGIN
DBMS_OUTPUT.PUT_LINE('outstr-->' || SF_ENCRYPTUTIL('12345'));
END;
Below code example using DBMS_CRYPTO. This works, but we do not want to use this.
declare
l_in_val varchar2(2000) := 'Test data 123';
l_mod number := dbms_crypto.ENCRYPT_AES128
+ dbms_crypto.CHAIN_CBC
+ dbms_crypto.PAD_PKCS5;
l_enc raw (2000);
l_enc_key raw (2000);
l_dec raw (2000);
begin
l_enc := dbms_crypto.encrypt
UTL_I18N.STRING_TO_RAW (l_in_val, 'AL32UTF8'),
l_mod,
HEXTORAW('156ae12300ccfbeb48e43aa016febb36'),
HEXTORAW('001122230405060708090a0b0c0d0e0f')
dbms_output.put_line ('Encrypted='||l_enc);
end;

I guess I'd be a bit curious about why you can't use a DBMS_CRYPTO solution that provides identical output. It seems odd to want to have a procedure running inside Oracle and then dictate that it has to be Java and not PL/SQL...
I verified the java.security file in jre/lib/security and I see that there is provider entry for SunJCE.
The jre version in Oracle is 1.4.2.Which java.security file are you talking about? The JVM that is inside the Oracle database does not and can not use configuration files that are outside the database. I suspect when you talk about files and paths that you're looking at a JVM outside the database, which is not the JVM that your Java stored procedure would be using.
Looking at the error, my assumption is that some JAR file needs to be loaded into the internal JVM in order for the AES algorithm to be available. But I'm unfortunately not familiar enough with these classes to say what that would be.

Using Custom Java Class - WorkflowRegistry.xml

I am using a custom java class in workflow. While executing I am getting errot -
com.waveset.util.WavesetException: Class com.LdapGroupMod is not a WorkflowApplication
It seems from documentation that I need to add this in workflowregistry.xml file. I added the same like given below -
<WorkflowApplication name='Workflow Name'
class='com.LdapGroupMod'>
<Comments>Nothing Here</Comments>
</WorkflowApplication>Even tried restaring the application server but I am still getting same error. Any idea what needs to be done here? or I am missing smething?

Well the first thing would be to read the workflowRegistry.xml file. The header talks about internal and external applications and so on. The crucial part is that any application registered must implement the WorkflowApplication interface (which I guess your class dont do)
I gave up. I am totally baffled by the documentation. I admit it.
What I did was to create an Script action in an Activity where the script used Xpress to invoke my class. It seems to work.

How to use the java class created by "CONTIVO" as web sevrvice?

Hi All,
We are creating the java class by the Contivo mapping tool, how to use that class as a web serivce?
Very thankful if anyone gives some light on this.
Thanks in advance.....

Re: Using simple java class in an .war file.

Hi All,
I have a simple question,
Can I access an simple java class from a jsp file that I have written by putting it in the "classes" folder?? What entry should go in the web.xml file?
Here is my directory structure:
sample.war
|
----test.jsp <file>
|
----WEB-INF <folder>
| |
| ----classes<folder>
| | |
| | ----simpleJavaClass.class<file>
| |
| ----lib<folder>
| |
| ----web.xml
I want to access the simpleJavaClass.class from the jsp test.jsp.
Please suggest.
Thanks and regards
Ayusman

It is possible to access the class in u r classes folder from u r jsp file.
For example
<%@ page import="com.test.service.PricingSolution,
com.test.core.PhoneNumber
%>
<% PricingSolution solution = (PricingSolution)session.getAttribute("solution"); %>
This is a simple scriplet example. You do the same using jstl tags also.

Creating data dictionary type using custom java class

Hi Experts,
I have a situation involving the TableSorter mechanism as described here:
In order to do my sorting correctly, I've created my own Java class implementing the Comparable interface. Based on this class, I need to define my own data dictionary type to be used in a context/table.
However, I cannot se how this could be achieved as standard Data Dictionary elements can only be based on simple built-in types. Any ideas?
Kind regards,
Rasmus Røjkjær Ørtoft

Hi,
have you tried to use the following steps while creating your attribute
1) Right click on the context
2) New->Attribute
3) Manually-> Provide a name for the attribute
4) Browse->Select java native type and select your class

Start JavaFx project using a Java class

After hours of searching, I still can't solve this problem:
I have a pure JavaFx project but need to start it with a Java class.
It used to work with the Interface method, but (I guess) since the javafx update to 1.3, the JavaFx code starts executing (the console outputs FX.println statements) but the stage(s) never become visible.
Activator.java
        final Context context = FXLocal.getContext();
        final FXClassType instance = context.findClass("javafx.Launcher", this.getClass().getClassLoader());
        final ObjectValue obj = (ObjectValue) instance.newInstance();
        final LauncherInterface l = (LauncherInterface)obj.asObject();
        l.run();LauncherInterface.java
public interface LauncherInterface {
    public void run();
}Launcher.fx
public class Launcher extends LauncherInterface {
    public override function run() {
// [...] init stuff
        MainWindow.createWindow();
}I'm using java version "1.6.0_21", javafx 1.3.0_b412, windows 7
any ideas?
thanks alot

There is someting wrong in my answer that on the FX side you can keep your code but on the java side the call have to be defered to the javaFX container like that:
com.sun.javafx.runtime.Entry.deferAction(
                new Runnable() {
                    @Override
                    public void run() {
                          //Create javaFX Stage
            );The class is in javafxrt.jar

Using normal java classes to access database

Dear friends,
Is it a good practice to make database calls from a normal java class within J2EE environment.
What I meant by a normal java class is a class which is not an enterprise bean.
Best Regards,
Chamal.

it is quite normal.
If you make your own DAOs, it may not be efficient/generic.
JSP/Servlets can use Hibernate (which is a set of POJOs) to access DB. Thus you have a J2EE environment using a very matured DB access methodoloy, and doing away with Enterprise bean.

How to use Spatial Java Class to update spatial data?

Hi,
I am new to Oracle and couldn't find enough information on how to update spatial data.
Here are my questions?
1)Where could I find Spatial Java Class Javadoc?
2)I'd like to update spatial data inside a ResultSet.next() loop.
After I got the Geometry object and Point object how do I change the x and y values of Point object and save it back to the database.
3)
GeometryAdapter sdoAdapter = OraSpatialManager.getGeometryAdapter("SDO", "8.1.6", null, STRUCT.class, null, conn);
Can I use the above GeometryAdapter for saving Geometry back to database?
4)
SpatialReference sref = srManager.retrieve(8265);
// SRID = 8265: LAT-LON (NAD 83)
Do I need to create a SpatialReference object and why retrieve the SRID '8256'? Do I have to create SRID '8256'?
Thanks for any help
Gwowen

You can find some sample code that shows you how to do that using
the SDOAPI java library. Look under the "Sample Code" section on
OTN's Spatial page:
http://otn.oracle.com/sample_code/products/spatial/content.html
The sample file SampleNewToSDO.java is what you will need.
hoep this helps,

How can I get past prob using MQ Java classes on HPUX (CCSID 1051 not sup)

I am working with MQSeries (Java classes for MQSeries MA-88) in an HP-UX environment.. I am not able to get from a queue using Java because apparently Java does not support code page 1051. Is there a way to get around this? I don't have the option of changing the default CCSID of the queue manager. I have heard something about being able to map CCSIDs using an HP-UX system call thru JNI but no details.. Any info would be appreciated.. What I am getting back from Java is "unsupported character set 1051" this is the default for HP-UX

Hi All,

Hello,
I have the same issue as stated above.
At runtime sometimes the mapping fails however when executing the mapping from ESR (test operation mapping) with the same payload it is executed succesfully (lookup is to system that is the senderservice of the scenario).
Anybody a clue.
Also clearing mapping cache etc. did not solve the problem.
Thanks,
