Java function activity getting deferred

Hi
I have created a simple Java Class File which set values to the item type attributes and return.
Placed the class file in jdk/bin folder.
Then i associated the class name to a function activity as “External Java” type. When i launched this process that function activity is moved to deferred state.
When i checked the WF_OUTBOUND_TABLE all the java related activities which i executed are still in the Queue.
And I tried by giving a wrong class name to a function, which is not at all in the server. That process activity also moved to deferred state without showing error.
So Java Function activity agent not even picks that function/class to process.
I tried the standard workflow provided by Oracle Workflow Standalone Server for demonstration. For that also same thing is happening (moving to deferred state).
Your help is much appreciated

Ariv

Hi,
Are you running the external processor for Java? IIRC, it's a .bat script which does the dequeue for you, calls your code, and then puts a message on the inbound queue - but it's been a LONG time since I looked at working with Java in standalone workflow.

Unable to start Java Function Activity Agent

When I try to start the Java Function Activity Agent
I get the following message:
Workflow JAVA Execution Agent
Oracle Workflow 2.6.0 JAVA Function Activity Agent
Error in parameters
Is there any way to tell what parameters it is referring to?
Thanks, Tom

Just to clarify:
The Oracle Workflow Java Function Activity Agent is supported by Oracle for the Database and Application Server releases. It was not certified for Oracle E-Business Suite customers, as we thought it better to focus our efforts on the Oracle Workflow J2EE Engine. In the next standalone releases, we will be provinding better system management for the Java Function Activity Agent, on demand processes, that sort of thing.
We did a lot of work to make sure that messages do not get lost ie. if an unexpected error is encountered, the transaction will get rolled back and the message will go back on the queue. If you are finding messages get lost, there are 2 possibilities: a bug in your code (ie. the transaction was committed in your code, so roll back would not help), or a bug in our code (a reproducible test case would be helpful).
Cheers

Java function activity agent fails

Hello,
Trying to run workflow java function activity agent ends with dr. Watson. Environment:
OS: NT40 sp 6
DB: 8.1.7.0.0
JRE: 1.1.8
Anybody came across this or is this a known problem? Please share your findings.
Thank you.
Anatoliy

Sorry,
The problem was with the wrong jar file.

What's Java Function Activity Agent?it's wfapi.jar?

pls explain the words below,tks a lot:
You must include the JAR files containing your custom classes in your
CLASSPATH to make the classes accessible to the Java Function
Activity Agent. The custom class files should reside on the same
platform where the Java Function Activity Agent is run. The Java
Function Activity Agent does not need to reside on the same tier as the
database, however.

Customized java class for an external Java function activity

Hi,
how can i customize my jdeveloper in order to build my own classes for external Java function activities ?
because any time i try to build my class the compiler tells me that it doesn't know WFFunctionAPI! And i do not have any idea neither which libraries i have to reference nor where i can find them. i tried to reference the *.jar file from my <ORACLE_HOME>.Wf.Java\Oracle\Apps\Fnd\Wf path, but the compiler still was mocking at me!
Thanks for your help
abi

In the "Project" menu, select "Project Properties";
In the "Libraries" tab, click the "Add" button;
Click "New";
Type "Oracle Workflow" (or any other name) in the Name field;
In the "Class path" field, click the "..." button;
Click "Add path" and select <ORACLE_HOME>/wf/java;
Click "Add ZIP/Jar" and select wfjava.jar and wfapi.jar from the <ORACLE_HOME>/wf/java/oracle/apps/fnd/wf/jar directory.
Click "Ok" in all those windows and compile your class.

How to use java api for function activity in embed oracle workflow?

because i can't install standalone oracle workflow successfully.
pls tell me how to use java api for function activity in embed oracle workflow?
are there some patch or pulg-in package?
ths a lot...........

The Java Function Activity Agent is not certified for Oracle Workflow embedded in Oracle Applications. Installing standalone workflow should be a lot easier than what you have found, although it looks like you did hit a Pentium 4 issue with the Oracle Universal Installer. I suggest you contact Oracle Support or Oracle Consulting for assistance.

Unable to run External Java activity getting Null pointerException

Hi All,
Im unable to run external java activity in my workflow on Solaris environment.
My workflow looks like:

Hi,
I am using integrated web logic server. Do I have to create JDBC connection in Integrated Weblogic Server? If yes, then how come it was working earlier and stopped working suddenly.
Just to try out, I have created JDBC with a name soademo (As mentioned in bc4j.xml) in Integrated Weblogic Server but didn't worked.
I will send you sample java class for your reference.
public class TestClient {
    public static void main(String[] args) {
        String amDef = "com.moj.model.AM.AppModule";
        String config = "AppModuleLocal";
        ApplicationModule am =
            Configuration.createRootApplicationModule(amDef, config);
        ViewObject emplist = am.findViewObject("EmployeesView1");
        emplist.setWhereClause("first_name = :p_firstname");
        emplist.defineNamedWhereClauseParam("p_firstname", null, null);
        emplist.setNamedWhereClauseParam("p_firstname", "Smith");
        emplist.executeQuery();
        while (emplist.hasNext()) {
            Row emp = emplist.next();
            System.out.println ("emp " + emp.getAttribute("Empno"));
            System.out.println("First Name " + emp.getAttribute("FirstName"));
            System.out.println("Last Name " + emp.getAttribute("LastName"));
        Configuration.releaseRootApplicationModule(am, true);
Appreciate if you can provide me in more detail as I have started working on very recently.

Is Function Activity execution synchronous/asynchronous?

Hi,
I would like to know the mode of execution of Function activity, that is whether it is synchronous/asynchronous?
Suppose if I have 2 activities in a process, one is of type PL/SQL and another is of type External Java. When I start the process from a java program, when will the calling program get the control back? will the exceution of each activity is synchronous or asynchronous?
thanks in advance
Regards
honnur

Thanx for the reply.
I find that if the function activity is of type PL/SQL then the calling function(WF Engine) waits till the PL/SQL procedure/function exection is complete. But if the function activity is of type External Java then the calling function(WF Engine) does not wait until the Java function execution is complete. In this case, when External Java Agent finishes the function excution, we have to explicitely invoke background process to complete that activity.
So the Java function activity execution is asynchronous from calling function perspective.
is my understanding right??
TIA

Is it possible to call Java functions from XSLT, using standard Java 6?

I have seen examples, but the examples are always the most simple case, which even I can already get working. The case where no arguments are passed to the java function.
As soon as I try to pass an argument to the java function, i get a stupid unhelpful error message (as always error messages are unhelpful).
Or am I wasting my time using the standard provided java parser, and need to use apache or something?
anyone who can provide me with a couple lines of working code is to me a saint!
At the moment I am using calling a named template, and passing a param into this.
I want to use this param as an argument in the Java function.
Is this possible?
example code:
     <xsl:template name="calc-age">
          <xsl:param name="dob"/>
     <xsl:variable name="sdob" select="java:lang.String.new($dob)"/>
     <xsl:value-of select="java:toString($sdob)"/>
     </xsl:template>

I have fixed it.
I had to call an xslt 1 function 'string' on the variable before passing it into the java function (see below).
     <xsl:template name="calc-age">
          <xsl:param name="dob"/>
          I know that the value of the param is: <xsl:value-of select="$dob"/><br/>
         <xsl:variable name="poo" select="$dob"/>
         <xsl:variable name="sdob" select="java:lang.String.new(string($poo))"/>
         And here again, we try to print a variable<xsl:value-of select="$poo"/>                <br/>
         And here again, we try to print the result of the java call<xsl:value-of select="java:toString($sdob)"/>      <br/>
         and here is our variable sdob    <xsl:value-of select="$sdob"/>
     </xsl:template>          Now this is APPARENTLY a xslt-1 function,
but the reference I had been using for this is
http://www.w3schools.com/xpath/xpath_functions.asp it is linked to by a reference that calls these xslt-2 functions.
Maybe they are mixed xslt-1 and xslt-2 functions?
How am I supposed to know?
Where is a good (plain and simple, easy to read) reference for xsl, so i know which functions are which?
Anyone got a good answer to that question?

Java downloading function FtpClien.get() do not work in Solaris 10

I wrote a java ftp code using java class provided by sun (sun.net.ftp.FtpClient). It worked nicely in Solaris8. After new update from Solaris8 to Solaris10, this function does not work anymore. Specifically this function "TelnetInputStream in = ftpClient.get(remotefilename)" does not work. It stucks there forever enven without giving an exception. Does anyone know this problem?
Thanks
P.S. I still can use the java function "ftpclient.put()".

Getting error while calling external Jars in BPEL by using Java embedding activity in soa 12c

Hi,
I am trying to use an external Jars for the business logic implementation. Here I need to pass XML as input and
and I expect the "Password " field has to be return.
Following are the steps I have followed:
1) Created a java project with sample class and added the external jars into the project "Libraries &Classpath".
2) Created a jar file out of it.
3) Created a BPEL project with Java Embedding.
4)Wrote the java code in java embedding activity.
4) Added the above created jar file to the BPEL project's lib/jar and added in SCA-INF/lib project folder as well.
5) Imported the package with the class as in the jar (e.g <bpelx:exec
import="pkg.testInterface"/>)
6) Deploy the BPEL project.
while deploying the SOA build is sucessful but my depoyment is incomplete.
error:
advices will be great....
Regards,
Dilip

Hi,
Can you confirm if the BPEL Version is 1.1 or 2.0.
If you are using BPEL 2.0 you need to import the required jar/class file as:
<import importtype="http://schemas.oracle.com/bpel/extension/java" location="pkg.testInterface"/>
For BPEL 1.1 the syntax to import other jar/class file is:
<bpelx:exec import="pkg.testInterface"/>
If you import the classes in the correct format you will not face any deployment error.
