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

Can anybody please point out what could be the problem....?
what is this t2cCreateState? I have never see this "t2cCreateState" when we run JFAA in unix box.
Any points will be appreciated..

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.

Java function activity agent fails

Hello,
Trying to run workflow java function activity agent ends with dr. Watson. Environment:

DB: 8.1.7.0.0

Anybody came across this or is this a known problem? Please share your findings.
Thank you.

Sorry,
The problem was with the wrong jar file.

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
Regards
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.

Hi Community,
I have to warm this topic again.
I'm facing the same problem like devender. I followed the posted advices, whithout any change. I also checked note 741289 - no change. I restarted the j2ee engine out of TA SMICM where I also checked the application server's state (j2ee Server Operational = FALSE) - no effect.
In SAPMMC I restarted the instance without any effect. The disp+work.EXE still has a yellow state, says "Running, Message Server connection ok, Dialog Queue time: 0.00 sec, J2EE status info unavailabe.
I think the developer trace says the same like devenders:

There's the solution manager running on the same server. In his instance everything's fine.
After changing some instance parameters i'm getting some errors:
1. Parameter Name: jstartup/instance_properties
   General standardvalue: $(jstartup/j2ee_properties)$(FILE_SEP)$(jstartup/sdm_propert
   Specified standardvalue: D:\usr\sap\EI3\D00\j2ee\cluster\instance.properties;D:\usr\s
2. Parameter Name: exe/j2ee

Ok, I think I got it. The specified standardvalues the system is selecting are wrong.....but how can I influence the systems selection?

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.

Unable to start java tools - Error : Environment variable JAVA_HOME not set

hi all,
I am not able to start the java tool - Visual Admin, Configtool, etc in the solaris Bash shell.
I was given authorizations on solaris and i'm able to view the logs and browse in solaris boxes,
But, when i try to start Visual Admin, it says" ERROR environment variable JAVA_HOME not set "
Since,my colleagues are using this tool for years, how come the environment variable is not set only for my user profile ?
Is it like the environment variable has to set seperately for every user profile ?
Do i need to set it initially for my profile eventhough it is working for others ?
i am confused..please help.
Addy

Nicholls, Thanks for your quick reply.
Ofcourse, I use my login ID to use java tools and they use their's obviously.I don't use <SID>adm.
We WRQ reflection for X-Windows and Putty for Command line Solaris Access.
When i try to use VA through the X-Window tool WRQ reflection, I am not able to start the tool.
My doubt here is, Do we need to setup the environment variable for every new user initially for the first time ? ( I am a new user for this environment )
Supposing if i need to setup the environment variable, do i need to set it up for the all the Solaris Boxes i use ?
I am able to browse through the files.when i try to start the VA by giving ./go i am not able to start it up.
Appreciate your time and valuable replies.

Application Unable to start Java inside Internet Explorer

Hi Good afternoon
Since last round of MS Win 8.1 PRO x64 Updates as of 16/11/2014, JAVA version 1.8 build 25 cant start inside Internet Explorer v11.0.14 Update KB: 3003057.
Even After Updating to EMET v5.1.5426
For example Cisco NetAcademy Environment Checker:
EMET detected ASR mitigation in IEXPLORE.EXE
ASR check failed:

If ASR is disabled in Internet Explorer everything runs flawlessly.
Please review EMET policies

When I browse to http://javatester.org/version.html (a site which uses Java but doesn't belong to my trusted sites) I get this message:
I don't get a EMET mitigation warning from the EMET 5.1 icon in the system tray (anymore) which I used to get with EMET 5.0. I also don't get a event in the application event log! When I add the site to the trusted sites Java starts and asks for permission
to start the applet because it isn't signed.
The message that the page requires Java is confusing because a user might think that Java isn't installed and may try to install Java again (and maybe not from the official install page but from a page with malware)....
Can you check some settings? Open the GUI of EMET 5.1, goto Apps, select IExplore.exe and click on 'Show All Setting'. You should see something like the image below.
Is the 'Trusted sites' zone selected?

Unable to start java VM for JDeveloper

I follwed the instruction in the release notes for JDeveloper 3.2.2 to use jdk 1.3.0.
I Set up my Windows NT shortcut like this: "C:\Program Files\Oracle\JDeveloper 3.2\bin\jdeveloper.exe" -jdk=1.3.0
I also tried the suggestion of modifying the jdeveloper.ini file. The result was the same.
I now get the error shown above.
Is there something else I have to do?

Hi,
Did you carry out the step which modifies the library.ini file make sure you have a
[JDK_java version "1.3.0"]
section?
If you have done this, check that all the paths in this section are correct.

Different ways of starting external java activity agent?

Hi All,
Can any one tell me different of ways of starting Oracle Workflow 2.6.4.0.0 JAVA Function Activity Agent in Solaris .
The one option i know is using shell script wfjvlsnr.csh.This option requires connection string to be given.
But according to the user of my application ,im allowed to use only datasource to get the workflow database connection.
Can any one please let me whether there is option to run java activity listner using Workflow database as datasource.
Thanks in advance.

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.

External Java Function with a Result Type

Dear all,
I have created a workflow process which use a Function Activity of type "External Java" without a result type and it works fine, but i have created another with the result type of boolean (WFSTD_BOOLEAN) and it doesn't work properly. I will explain what is happening.
I start a process and it stops in that function activity, then the oracle Function Activity Agent executes the class associated to that function and it works fine. Then i review the workflow process and check that the status of the activity is "Deferred". I execute the wf_engine.background process, and then the status of the activity is "Complete" but the result field is blank, thus the process is stopped and did not go through the "True" branch of the process. I have follow the Oracle Workflow and Java Technical White Paper to build the class associated to the function activity, and i return true in the execute method and don't put anything in the errorStack variable.
The documentation says:
resultOut If a result type is specified in the Activities properties page for the activity in the Oracle Workflow Builder, this parameter represents the expected result that is returned when the procedure completes.
Note: Unlike the resultout for a PL/SQL procedure called by a function activity, the resultOut for a Java procedure does not include a status code. In the Java API, only the result type value is required. The status of the activity will be set automatically by the Workflow Engine depending on whether there is a value in the errorStack variable.
am I doing something wrong? could anyone help me?
Thanks in advance.

Hi Allison,
I've found the solution to the problem. If i set the variable resultOut to "T" or "F" before finnishing the execute method it works.
I think that you have to set the variable resultOut with the internal value of the lookup type that you are using as the result type of the function activity.
Bye!

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
