11g Updating instance variable
How do update instance variable at runtime. e.g say my workflow instance wating at 'InProcess' HumanTask with instance variable wrkStatus='IP'..now with out executing the HT how can we update the 'wrkStatus' variable to 'IR'....?
NOTE : in 10g we can do that using global interactive with instance access....but i have no idea abt 11g :(
Rgds,
Biltu
Thanks for your reply Mariano.
But that will be before the Token reaches to my Human task....we can do that..using association.....
But my doubt is different..lets assume i have moved to my human task ..now I need to update my instace data.
e,g I enter to HumanTask1 with a req msg
<UserReq>
<Name>nam1</name>
<address>addr1</address>
</UserReq>
now I want to update address by 'addr2'.

Update Instance Variables using PAPI
I have a need to update Instance Variables for a bunch of instances. Can this be done using PAPI? I am writing a global function that can search the instances and update. How can I update these variables...thank you
Hi,
I think that the best way of changing instance variables using papi is by adding a global activity (with instance access) and pass the new variable values as arguments. Pay attention that you have to define those arguments in the activity.
Then, you can assign those values to the instance using PBL.
http://download.oracle.com/docs/cd/E13154_01/bpm/docs65/papi_javadocs/fuego/papi/ProcessServiceSession.html#activityExecute(fuego.papi.Activity,%20fuego.papi.InstanceInfo,%20fuego.papi.Arguments)
I do suggest avoiding sending interruptions to instances, because once the notification is sent (and the papi method returns successfully), the notifications will be processed in another transaction.
Hope this helps,

Binding a JavaFX variable to a Java class instance variable
Hi,
I am pretty new to JavaFX but have been developing in Java for many years. I am trying to develop a JavaFX webservice client. What I am doing is creating a basic scene that displays the data values that I am polling with a Java class that extends Thread. The Java class is reading temperature and voltage from a remote server and storing the response in an instance variable. I would like to bind a JavaFx variable to the Java class instance variable so that I can display the values whenever they change.
var conn: WebserviceConnection; // Java class that extends Thread
var response: WebserviceResponse;
try {
conn = new WebserviceConnection("some_url");
conn.start();
Thread.sleep(10000);
} catch (e:Exception) {
e.printStackTrace();
def bindTemp = bind conn.getResponse().getTemperature();
def bindVolt = bind conn.getResponse().getVoltage();
The WebserviceConnection class is opening a socket connection and reading some data in a separate thread. A regular socket connection is used because the server is not using HTTP.
When I run the application, the bindTemp and bindVolt are not updated whenever new data values are received.
Am I missing something with how bind works? Can I do what I want to do with 'bind'. I basically want to run a separate thread to retrieve data and want my UI to be updated when the data changes.
Is there a better way to do this than the way I am trying to do it?
Thanks for any help in advance.
-RichardHi,
If you don't want to constantly poll for value change, you can use the observer design pattern, but you need to modify the classes that serve the values to javafx.
Heres a simple example:
The Thread which updates a value in every second:
// TimeServer.java
public class TimeServer extends Thread {
private boolean interrupted = false;
public ValueObject valueObject = new ValueObject();
@Override
public void run() {
while (!interrupted) {
try {
valueObject.setValue(Long.toString(System.currentTimeMillis()));
sleep(1000);
} catch (InterruptedException ex) {
interrupted = true;
}The ValueObject class which contains the values we want to bind in javafx:
// ValueObject.java
import java.util.Observable;
public class ValueObject extends Observable {
private String value;
public String getValue() {
return this.value;
public void setValue(String value) {
this.value = value;
fireNotify();
private void fireNotify() {
setChanged();
notifyObservers();
}We also need an adapter class in JFX so we can use bind:
// ValueObjectAdapter.fx
import java.util.Observer;
import java.util.Observable;
public class ValueObjectAdapter extends Observer {
public-read var value : String;
public var valueObject : ValueObject
on replace { valueObject.addObserver(this)}
override function update(observable: Observable, arg: Object) {
// We need to run every code in the JFX EDT
// do not change if the update method can be called outside the Event Dispatch Thread!
FX.deferAction(
function(): Void {
value = valueObject.getValue();
}And finally the main JFX code which displays the canging value:
// Main.fx
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.text.Text;
import javafx.scene.text.Font;
import threadbindfx.TimeServer;
var timeServer : TimeServer;
var valueObjectAdapter : ValueObjectAdapter = new ValueObjectAdapter();
timeServer = new TimeServer();
valueObjectAdapter.valueObject = timeServer.valueObject;
timeServer.start();
Stage {
title: "Time Application"
width: 250
height: 80
scene: Scene {
content: Text {
font : Font {
size : 24
x : 10, y : 30
content: bind valueObjectAdapter.value;
}This approach uses less cpu time than constant polling, and changes aren't dependent on the polling interval.
However this cannot be applied to code which you cannot change obviously.
I hope this helps. -
Stateless Bean - scope of instance variable in EJB Timer call back function
Hi,
I would like to know on the scope of an instance variable of a Stateless Bean object,
when used in a EJB Timer call back.Let me explain this in more detail below.
I have a requirement to use a EJB Timer.
For this, I have created a stateless object since Timer creation needs to be done
from a stateless bean. I have a member variable "count" of the stateless bean class.
In the timer call back(ejbTimeout), I am able to use this count variable during
each time of the call back, and the value of this variable is also updated properly.
I have a few queries with respect to the above behaviour:
1) Does stateless bean object not get destroyed once the Timer is created from the Bean?
2) If the Bean object is not destroyed, then when does the bean object get destroyed?
3) If both (1) and (2) are not true, then can anyone explain on how the above behaviour is possible?
Thanks in advance,
UlrichHi Ulrich,
The ejb timer is associated with the stateless session bean component, not with a particular bean instance. There is no formal relationship between the bean instance that called createTimer() and the bean instance on which the timer callback happens. If they're the same in your test run that's just a coincidence and not something your application should be depending on.
In the stateless session bean model, the container can create and destroy stateless session bean instances at any time. The container is free to pick any stateless session bean instance to service any client invocation or timer callback. If you need to pass context into a timer callback, one way to do it is via the timer "info" object. However, the info object is immutable so it wouldn't be a good match for a counter. You could of course always just use a database for any necessary coordinated state.

Hi,
I am currently evaluating this tool for a specific user group. I had a question in mind :
In a typical workflow which involves database connections (i.e. inserting data in a database and displayign data) do you think we should pass data between various activities and users using instance variables or do you think we should retrieve data from the tables every time for display etcI would suggest get the data from the database first time and then store it in instance variables. Whenever, you need to update any values in the database from a particular activity, make a call to database to update it with the values from instance variables.
For displaying, use instance variables. You do not need to get fresh data from database for each activity, unless you think that data in database keeps changing for that particular records every day.

Hi
I have a question regarding size of normal instance variable.
It has been mentioned in the Studio 5.7 doc that the total size of all the instance variable for a project should not exceed 2Mb.
Question is that if it exceeds more than 2Mb than what would be its effects. Is there any exception thrown if size exceeds above 2Mb.
Also how can this be prevented as actual size can only be calculated at runtime.
Thanks in advance.The instance size exceeding the setting you have inside your Engine will cause errors to start appearing in the log file. The effect is that your engine's performance will degrade. Once you start getting Error messages, they are usually sent via email to the admin you specify in the Engine's settings.
A few ways to keep the size of the instance variables down is to:
1) change the category of large instance variables to "Separated" from "Normal". This means that they are not stored as part of then instance's BLOB stored in the PPROCINSTANCE Engine database. They are then only read from the Engine's separated instance variable table when they are needed in the activity's logic or updated only when modified in the activity. Separated instance variables are not calculated as part of the overall size of the instance.. Large binary variables not marked as Separated will quickly run you over your instance size limit.
2) Similarly, we sometimes treat the process instance variables as a database of record. Avoid this mentaility if possible. It's often better to have an external database to store information about things going on in the process. If you rely on the Engine tables for this for very large objects they are not easily retrieved by outside applicaitons because they are stored as a single BLOB. If outside applications access the Engine's database, it's another sure fire way to further degrade engine performance. Many times it' is better to store the id of a customer in the process and then to use that id to retrieve customer insformation from the cutomer's external database table. Once an instance has reached the End activity in a process, it sits there the number of days you specified in an Engine setting. Once it exceeds this number of days in the End activity, the instance data information is either purged or moved to the archive database. Don't make this number of days in the End activity too long (default is 15) as this will increase the sized of the number of rows on the table and degrade performance.
Hope this helps,

Jdev11 complains about public instance variables, but not Jdev10
Hi all, if I fire up Jdeveloper10 I can declare a public instance variable. (OK, stylistically maybe not a good thing, but nothing in the java 'rules' that says I shouldn't be able to do this.) However in Jdeveloper11 it complains, it underlines it in red and grumbles "should not have greater than protected access."
Anyone know where to turn off this compiler hint?
thanks.
public class Thing() {
public String bob; // complains in jdev11, ok in jdev10.Hi Kevin, thanks for the tip. It's taken me years just to remember where to turn on the line numbers in 'preferences' , so I would never have found that one about the instance variable checks ! Frank, thanks for the update, I agree it's useful as a stylistic hint, but I think that the Jdev floating code assist, rather than just hinting "declare this field protected" (as this will obviously fix it) would be more user-friendly if it also said "or disable under preferences - code assists." But Jdev11 is growing on me, tons of cool stuff :-)
thanks all. -
Parsing XML and Storing values in instance variable
hi,
i'm new to XML.
here i'm trying to parse an XML and store their element data to the instance variable.
in my main method i'm tried to print the instance variable. but it shows "" (ie it print nothing ).
i know the reason, its becas of the the endElement() event generated and it invokes the characters() and assigns "" to the instance variable.
my main perspective is to store the element data in instance variable.
thanks in advance.

You are assigning the value of localName to ctElement, however for the element: <name>...</name> the localname is empty string i.e. "", but qName equals "name". Because you are assigning empty string to ctElement, when you do the comparison in characters of ctElement to "name" it will always be false. So in startElement change it to ctElement = qName; Try it and see if it works. I have produced similar programs and it works for me.

How to use an BPM Instance Variable in JSP page
Hi All,
I am using the JSP Presentation, but i don't know how to use an Instance variable in JSP page, that instance already declared in the process. And Can u explain the syntax that to include the JS file into jsp page
Regards
Vasu.
Edited by bpmvasu at 04/03/2007 10:43 PMHi Mariano,
I'm using JSP presentation too. In "Interactive Component Call" active i'm using "Use JSP presentation", but i only can define one instance variable, i need to add more instance variables. In "Advanced" option of this task, i have the argument mapping .. but i don't understand how to use it.
I have a instance variable called "genders" of the type String[Int] (Associative Array) and i'm mapping this instance variable in "Arguments Show In" option of the advanced option of JSP presentation. In JSP presentation i have the code:
<select <f:fieldName att="person.gender"/>>
<c:forEach var="gender" begin="0" items="${genders}" varStatus="status">
<c:choose>
<c:when test="${person.gender == gender}">

</c:when>
<c:otherwise>
<option value="<c:out value="${gender}"/>"><c:out value="${gender}"/></option>
</c:otherwise>
</c:choose>
</c:forEach>
</select>And in my screenflow i have the code:
genders[0] = "Male"
genders[1] = "Female"But when i run my application, i have the error: "The task could not be successfully executed. Reason: 'java.lang.ClassCastException: java.lang.Integer'."
What's the problem? -
How to change value of instance variable and local variable at run time?
As we can change value at run time using debug mode of Eclipse. I want to do this by using a standalone prgram from where I can change the value of a variable at runtime.
Suppose I have a class, say employee like -
class employee {
public String name;
employee(String name){
this.name = name;
public int showSalary(){
int salary = 10000;
return salary;
public String showName()
return name;
i want to change the value of instance variable "name" and local variable "salary" from a stand alone program?
My standalone program will not use employee class; i mean not creating any instance or extending it. This is being used by any other calss in project.
Can someone tell me how to change these value?
Please help
Regards,
Sujeet SharmaThis is the tutorial You should interest in. According to 'name' field of the class, it's value can be change with reflection. I'm not sure if local variable ('salary') can be changed - rather not.

JDev 11g update 1 base edition on windows: error building default domain
Hi all,
(refer to [url http://forums.oracle.com/forums/thread.jspa?messageID=3168105]here for original post)
I'm posting this again with some more information. When downloading the Studio Edition (Base - no JDK) version of JDeveloper 11g update 1, an error occurs upon first (and each subsequent) startup of JDeveloper (error details below).
Tests that I have done:
1). Install using JDK 6 u 11 - JDK did not show up automatically in the installer, had to browse to find it and select it. Running using 6u11, 6u10, and 6u7 (deleting the system directory after each try) - error occurs.
2). Install using JDK 6 u7 - JDK was automatically found by the installer. Running using 6u7, 6u11, and 6u10 (deleting the system directory after each try) - error occurs
These errors do not occur when using the Windows installer. For information: my machine is Windows 2008 Server Standard 32-bit. An update - I just tried this on a Vista 64-bit laptop (running Sun 32-bit JDK 6u10) and did not have the problem. Ergo, this seems to be an issue with the JDK and detecting Windows 2008 as a Windows platform (or possibly with whatever mechanism JDev/WLS is using to detect the OS platform). I'll do more research on that and update if I find anything.
One more update: I didn't find any issues reported like this related to Windows 2008, but I did one more test: install and run JDeveloper using:
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
BEA JRockit(R) (build R27.6.0-50_o-100423-1.6.0_05-20080626-2105-windows-ia32, compiled mode) The issue does not occur using this JDK. So to summarize, installing JDev 11g update 1 Studio edition, base installer using any of the SUN JDK's on Windows 2008 gives this problem. Using the windows installer or JRockit Mission Control JVM - no problems.
Finally, one last update - the error is related to the JVM that is used to install, not the one used to run JDeveloper (via editing jdev.conf) - the offending JDK is in wlserver_10.3\common\bin\commEnv.cmd. Seems like a no-no to have one JDK running JDev and another running the integrated WLS, though. Quite a pity, as JDev starts up pretty slowly using JRockit Mission Control.
JRockit Realtime seems to be a bit faster... sigh - now to remove the 72 extra JDK's on my laptop ;)
My going forward plan: use the Windows installer. Wish I never installed Windows Server 2008.
Now for the error details; the log shows:
ERROR: An error occurred while building the default domain.
Please see this log file for more details:

Best,
JohnHi all,
(refer to [url http://forums.oracle.com/forums/thread.jspa?messageID=3168105]here for original post)
I'm posting this again with some more information. When downloading the Studio Edition (Base - no JDK) version of JDeveloper 11g update 1, an error occurs upon first (and each subsequent) startup of JDeveloper (error details below).
Tests that I have done:
1). Install using JDK 6 u 11 - JDK did not show up automatically in the installer, had to browse to find it and select it. Running using 6u11, 6u10, and 6u7 (deleting the system directory after each try) - error occurs.
2). Install using JDK 6 u7 - JDK was automatically found by the installer. Running using 6u7, 6u11, and 6u10 (deleting the system directory after each try) - error occurs
These errors do not occur when using the Windows installer. For information: my machine is Windows 2008 Server Standard 32-bit. An update - I just tried this on a Vista 64-bit laptop (running Sun 32-bit JDK 6u10) and did not have the problem. Ergo, this seems to be an issue with the JDK and detecting Windows 2008 as a Windows platform (or possibly with whatever mechanism JDev/WLS is using to detect the OS platform). I'll do more research on that and update if I find anything.
One more update: I didn't find any issues reported like this related to Windows 2008, but I did one more test: install and run JDeveloper using:
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
BEA JRockit(R) (build R27.6.0-50_o-100423-1.6.0_05-20080626-2105-windows-ia32, compiled mode) The issue does not occur using this JDK. So to summarize, installing JDev 11g update 1 Studio edition, base installer using any of the SUN JDK's on Windows 2008 gives this problem. Using the windows installer or JRockit Mission Control JVM - no problems.
Finally, one last update - the error is related to the JVM that is used to install, not the one used to run JDeveloper (via editing jdev.conf) - the offending JDK is in wlserver_10.3\common\bin\commEnv.cmd. Seems like a no-no to have one JDK running JDev and another running the integrated WLS, though. Quite a pity, as JDev starts up pretty slowly using JRockit Mission Control.
JRockit Realtime seems to be a bit faster... sigh - now to remove the 72 extra JDK's on my laptop ;)
My going forward plan: use the Windows installer. Wish I never installed Windows Server 2008.
Now for the error details; the log shows:
ERROR: An error occurred while building the default domain.

Instance variable to hold the element of a tag in the xml file
Hi I have an xml file that is handled using this parser
<attr id="MY_NAME" >
this parser hanled the above tag but now I want to have it handle
<attr id="MY_NAME" desc="GOOD">
but I need to create an instance variable to handle the desc element in the attr tag .
Can some one help me out as this is not my file and I am having trouble to do please......

The SupportMatrix class provides static variables and methods to simplify
the determination of whether or not a given attribute is supported for a
certain object type (queue manager, channel, etc.), depending on the version
and platform of the queue manager to which it belongs.
The SupportMatrix class may not be instantiated. Its constructor is private.
An instance of the class is created internally in the static initializer so
that the XML parsing methods are available.
A corresponding XML document, SupportMatrix.xml, is parsed to create the various
HashMaps which contain the version/platform dependency information. A number of
inner classes are used to represent the various elements of the XML matrix
definition.
Here's a sample document:
<!-- The supportmatrix tag opens the document -->
<supportmatrix>
<!-- Objects are keyed by classid. "1" is the classid of a queue manager object. -->
<object classid="1">
<!-- Versions group attributes according to the queue manager version where they
were introduced. The "base" cmdlevel encompasses all versions up to 5.1. -->
<version cmdlevel="base">
<!-- Attributes are defined by the attr tag. -->
<attr id="MQCA_Q_MGR_NAME">
<!-- Support elements define the platform-specific requirements for an attribute. -->
<support platforms="UNIX,WINDOWS,OS400,VMS,NSK" maxlen="48" type="MQCFST"/>
<support platforms="MVS" maxlen="4" type="MQCFST"/>
</attr>
<attr id="MQCA_Q_MGR_DESC">
<!-- Specific attribute characteristics, most notably maximum len for string parms,
are defined in the support element. As shown in the following example, it may
apply to all platforms. -->
<support platforms="all" maxlen="64" type="MQCFST"/>
</attr>
<!-- Support elements are optional. -->
<attr id="MQIA_PLATFORM"/>
<attr id="MQIA_COMMAND_LEVEL"/>
</version>
<!-- The version element may 'include' other versions. Note that object elements
may also refer to other objects via the 'include' parm of the object tag.
This is to allow common attributes (especially for queues and channels) to
be shared by multiple definitions in order to reduce some of the
redundancy. -->
<version cmdlevel="520" include="base">
</version>
</object>
</supportmatrix>
The inner classes, and their hierarchical relationships are as follows:
SupportObject - corresponds to the <object> element. Stored in a static HashMap, and
keyed by classid.
VersionObject - corresponds to the <version> element. Stored in a HashMap instance
variable of the SupportObject class, keyed by cmdlevel.
AttributeObject - corresponds to the <attr> element. Stored in a HashMap instance
variable of the VersionObject class, keyed by attribute name.
PlatformObject - corresponds to the <support> element. Stored in HashMaps belonging
to the AttributeObjects, keyed by platform. A single PlatformObject
instance is created when the support tag is encountered. The
"platforms" attribute of the support element is then processed. For
each platform in the comma-delimited list, an entry is added to the
collection of PlatformObjects. This is to greatly simplify later
lookups.
In order to support the 'include' feature of object and version elements, certain
functions are recursive. If the attribute to be validated is not found for the passed
cmdlevel, the 'parent' VersionObject is consulted by means of the 'include' value. If
the chain of VersionObjects has been exhausted and the attribute in question has still not
been located, the next SupportObject in the chain is consulted in a similar fashion.

}Are you the one who commented out the code you're looking for ?//String desc = StringFactory.getString(attributes.getValue("desc"));You just have to modify you AttributeObject class to hold a new field : String description. And then, it's up to you to create a new constructor or a new setter method.
Btw, this is not a Swing related question. -
How can I use evaluate to get the instance variable in customized tag
1.
At first , I create a class called bean,and declared several params in it and do not define any getter function for the param.
class bean{
String param = "test";
SomeClass scObj = new SomeClass();
2.
The second ,I use
request.setAttribute("beanObj",new bean());
3.
And then I wanna use the customized tag to show a text box , then initialize it's value.
<salt:text name="param" value="beanObj.param">
<salt:text name="obj" value="beanObj.scObj.func()">
4.
I tried the evaluator provided by JexlContext ,Struts, JSTL and it seems that if I do not define the getter for the variable ,I can not get the bean's instance variable's value.
Expression e = ExpressionFactory.createExpression( value );
JexlContext jc = JexlHelper.createContext();
jc.getVars().put(strInitBeanName, request.getAttribute("beanObj"));
Object obj = e.evaluate(jc);
the result of the obj is null....
Can anybody recommand some other evaluator can get the value of a instance variable from an object?do you have any other suggestion ? Nops, somebody else may have though. AFAIK, all lookups of the type
beanName.propertyNameuse reflection on the getXXX() methods to access the property.
Having said that, I guess you could write one though in a custom tag, using the same - reflection (you will ahve to rely on the java.lang.reflect.Field class quite heavily) - but that would be reinventing the wheel for most other functionality that you would have to include (like looking up the bean in scope etc)

Profit Center Hierarchy is not updating in Variable
HI Guru's,
Profit Center Hierarchy is not updating in Variable .
We have 3 new profit center added of which i have updated the master data ie, attr, txt, and hierarchy and Txn data. Where after updating i can find the thing updated but when i execute the report in the variable i dont find the updated profit center.
Please guide
PrasadBut just to update you that we don't have data for the new profit centerin R3. Is it because of this i don't find the new profit centers in
Variable screen ( though i can see in Query Designer)
Please guide
