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

Trying to invoke a Java class from BPEL Proces using Java Embedding

Hi All,
I have a requirement to invoke a Java class from the BPEL process;
I am trying to import the class by "* <bpelx:exec import="+package_name.classname+"/>*.
But, while compiling, I get the following error:
"Error(19,57): Failed to compile bpel generated classes. failure to compile the generated BPEL classes for BPEL process "BPEL_PROCESS_NAME" of composite "default/COMPOSITE_NAME!1.0"
The class path setting is incorrect. Ensure that the class path is set correctly. If this happens on the server side, verify that the custom classes or jars which this BPEL process is depending on are deployed correctly. Also verify that the run time is using the same release/version."

Can we call Java class from LiveCycle Process?

hi..
I have a general query, is it possible to call customeized java class from Workbench Process?
I found dat we can invoke a web service... is there some operation like that for calling a java class...
Thanks and Regards,
Ambika

Yes.
You can use the Script service and put your Java code in there
Or build your own component, which is really a Java pojo, and deploy it to LiveCycle. See http://livedocs.adobe.com/livecycle/8.2/programLC/programmer/help/000934.html.

Accessing Java Classes from Forms

Is is possible to access a Java class from Forms? I have been

How do you invoke custom java classes???

Could someone post a detailed method of invoking custom java classes that works including what files go where, settings and the way it is invoked etc.
I have tried various ways from this forum and in the documentation without success. I am using IDM 8. I found these instructions regarding how you would do it if you were writing custom resource adaptors in the deployment tools guide:
To install a resource adapter youve customized:
1. Load the NewResourceAdapter.class file in the Identity Manager installation
directory under
idm/WEB-INF/classes/com/waveset/adapter/sample
(You might have to create this directory.)
2. Copy the .gif file to idm/applet/images.
This .gif file is the image that displays next to the resource name on the List
Resources page, and it should contain an image for your resource that is
18x18 pixels and 72 DPI in size.
3. Add the class to the resource.adapter property in
config/waveset.properties.
4. Stop and restart the application server. (For information about working with
application servers, see Identity Manager Installation.)
I tried the instructions here but placed my custom class in a folder entitled custom instead of /adapter/sample. Not sure about instruction 3 or whether it is relevent. Anyway nothings working.

Edited by: masj78 on Nov 25, 2008 4:03 AM

Hi,
The way to add custom class is the same as you followed , put them in the WEB-INF/classes.
To use the custom adapter ,
Go To Resources - > Configure Types -> Add Custom Resource .
Type in the fully qualified class name of the custom adapter you added.and Save.
Now the new adapter you added should showup in the list of available adapters when you try to
configure a new adapter.
(Make sure that the prototype XML of your custom adapter is correct so that it displays the correct name / type for the adapter in the adapter list.
Thanks,

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.

Invoking a java class while server start up

Hi,
I want to invoke a java class/method immediately after a web server is started. Can any body tell me how to do this.
Regards,
Prakash

It is easy.
Write a serlvet, lets call it ConfigServlet that handles the configuration parameters of a web-application.
My GenericConfigServlet looks like this:
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Enumeration;
import java.util.Map;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
public class GenericConfigServlet extends HttpServlet
     private static final long serialVersionUID = 1L;
     public void init(ServletConfig config) throws ServletException
          super.init(config);
          ServletContext sCtx = getServletContext();
          ServletConfig sCfg = getServletConfig();
            String prefix = sCtx.getRealPath("/");
            synchronized (this)
               Enumeration initParams = sCfg.getInitParameterNames();
               String key, value;
               GenericConfigProperties.setApplicationBasePath(prefix);
               while (initParams.hasMoreElements()) {
                    key = (String) initParams.nextElement();
                    value = sCfg.getInitParameter(key);
                    GenericConfigProperties.setProperty(key,value);
}Then in your web.xml, you write like this:
<servlet-name>ConfigServlet</servlet-name>
          <servlet-class>GenericConfigServlet</servlet-class>
          <init-param>
               <param-name>LICENSES</param-name>
               <param-value>1</param-value>
          </init-param>
          <init-param>
               <param-name>TMP_DIRECTORY</param-name>
               <param-value>C:\\temp\\</param-value>
          </init-param>
          <init-param>
               <param-name>INPUTFILE</param-name>
               <param-value>C:\\temp\\_input.txt</param-value>
          </init-param>
          <load-on-startup>0</load-on-startup>
     </servlet>You can add any number of init-param-tags.
The important thing is the element <load-on-startup>0</load-on-startup>. This tells the webserver to load this servlet first. A lower number is loades before a higher so if you have a servlet that you want to load but you need the configuration to be done first, that servlet definition should read <load-on-startup>1</load-on-startup>.
Of course, you can do anything you want in the init-method. This is just one way of doing it.

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.

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.
Loading Java:
http://otn.oracle.com/docs/products/oracle8i/doc_library/817_doc/
java.817/a83728/03write6.htm

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.

Generate Java class from Oracle Type defined in Package w/ JPublisher

I was wondering if its possible to generate a Java class for an Oracle Type defined in a Package? I know passing the package name to JPublisher (SQL <package_name>) causes all Oracle Types in the Package to have a Java class generated for them but I'd like to be able to do this for an individual Type defined in a Package (something like SQL <package_name>.<type_name>).
Thanks for any information you can give me.

Hi Marinel,
The support for XSD import is limited on 10.1.2. If you can, you should consider moving to the 10.1.3 preview as the support for document style web services has improved. The other option will be to inline the schema in your WSDL.
