Can allocation of Java objects from JNI trigger GC?

A coworker of mine claims that if you do JNI calls in C to allocate memory, e.g., NewObjectArray(), and if there is currently insufficient memory on the Java side, that the call will fail without having run garbage collection, i.e., JNI memory allocation calls never trigger garbage collection.
Is this true? If so, it seems wrong, i.e., it should trigger GC just like an allocation in Java does. If so, why is it this way?
- Paul

I can't find anything about GC one way or the other
in the JNI spec, but Java's a GC-based language. If
it didn't perform GC for JNI allocation, or in
any other circumstance, I would expect to find that
spelt out in the appropriate documentation.
There's no statement about GC being performed if
necessary during execution of the new operator in the
JLS either. In fact I can't find much about GC
anywhere in the JLS, at least in the index, except
where it discusses finalization. That doesn't mean it
doesn't happen.I was just....hmmmm...duplicating it for emphasis (yeah that is it.)

How can i return an object isn't java object from webservice????

Hi !
I have a problem in my Project. When i call method return a java object from webservice , it 's too easy. But when i create my own object (ex:ClientRequest.class) , it doesn't work exactly T_T . When i return that object (on client, doesn't have ClientRequest.class) , i cann't access its static variables.
How can i do it ??
Please help me !
Thanks a lot !!!!!
class ClientRequest {
public static int i;
public static String s;
public ClientRequest() {
}

You can use REFCURSOR type for this. In java SQL TYPES this is available too. In your PLSQL use REFCURSOR for that array and then take the same from java code. Look in the servelet programming book for this SQLTYPE and see PLSQL for handling refcursors. We have done this way and it works.

How to reference multiple instances of the same Java object from PL/SQL?

Dear all,
I'm experimenting with calling Java from PL/SQL.
My simple attempts work, which is calling public static [java] methods through PL/SQL wrappers from SQL (and PL/SQL). (See my example code below).
However it is the limitation of the public static methods that puzzels me.
I would like to do the following:
- from PL/SQL (in essence it needs to become a forms app) create one or more objects in the java realm
- from PL/SQL alter properties of a java object
- from PL/SQL call methods on a java object
However I fail to see how I can create multiple instances of an object and reference one particular object in the java realm through public static methods.
My current solution is the singleton pattern: of said java object I have only 1 copy, so I do not need to know a reference to it.
I can just assume that there will only ever be 1 of said object.
But I should be able to make more then 1 instance of an object.
To make it more specific:
- suppose I have the object car in the java realm
- from PL/SQL I want to create a car in the java realm
- from PL/SQL I need to give it license plates
- I need to start the engine of a scpecific car
However if I want more then 1 car then I need to be able to refrence them. How is this done?
Somehow I need to be able to execute the following in PL/SQL:
DECLARE
vMyCar_Porsche CAR;
vMyCar_Fiat CAR;
BEGIN
vMyCar_Porsche = new CAR();
vMyCar_Fiat = new CAR();
vMyCar_Porsche.setLicensePlates('FAST');
vMyCar_Porsche.startEngine();
vMyCar_Fiat.killEngine();
END;
Thanks in advance.
Best Regards,
Ruben
My current example code is the following:
JAVA:
===
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED CODAROUL."RMG/BO/RMG_OBJECT" as package RMG.BO;
public class RMG_OBJECT {

private String rmgObjectNaam;
private RMG_OBJECT(){
this.rmgObjectNaam = "NonDetermined";
public static String GET_RMGOBJECT_NAAM () {
String toestand = null;
if (_instance == null) {toestand = "DOES NOT EXIST";} else { toestand = "EXISTS";};
System.out.println("instance : " + toestand);
System.out.println("object name is : " + _instance.rmgObjectNaam);
return _instance.rmgObjectNaam;
public static Integer SET_RMGOBJECT_NAAM (String IN)
try
_instance.rmgObjectNaam = IN;
return 1;
catch (Exception e)//catch
System.out.println("Other Exception: " + e.toString());
e.printStackTrace();
return 5;
} //catch
PL/SQL Wrapper:
==========
CREATE OR REPLACE FUNCTION CODAROUL.SET_RMGOBJECT_NAAM(NAAM IN VARCHAR2) return NUMBER AS
LANGUAGE JAVA NAME 'RMG.BO.RMG_OBJECT.SET_RMGOBJECT_NAAM (java.lang.String) return java.lang.Integer';
Calling from SQL:
==========
CALL dbms_java.set_output(2000);
select CODAROUL.GET_RMGOBJECT_NAAM() from dual;

You can do this by manually creating a new iterator binding in your binding tab.
So instead of dragging the VO directly to the page, go to the binding tab, add a new executable iterator binding, and point to that one from your ELs in the page itself.

Dropping java object from Oracle 8i

We areaable to load java methods and publish them to SQL in Oracle 8i using Jdev Deploy wizard, but we can not drop them thru
Open View As->Database Browser of the connection object, they drop menu is greyed out/disable. What kind privilege we need to drop java object from Oracle 8i? Or there is something wrong with the database setup.
Thank you very much

There are three options:
Normal
SysDBA
SysOper
I have tried the three of them, none of them works, is there third option SYS?
Thank you very much.

Access Java object from Javascript

Hi
I'm trying to invoke a Java object from Javascript (scriptengine and all that).
I want to add scripting features to a GeneXus Java generated app... and I have very basic skills on java too. Sorry for that ;o).
This is the java code to pass "params" to the scriptengine:
engine.put("remoteHandle",remoteHandle);
engine.put("context", context); The remoteHandle (int) and context (com.genexus.ModelContext) pass trough all the gx-java generated programs.
This javascript works fine:
importClass(Packages.uftestjs);
new uftestjs(remoteHandle).execute( ) ;The remoteHandle conversion is ok (javascript-number to int). The context is optional.
But if I want to pass context:
importClass(Packages.uftestjs);
new uftestjs(remoteHandle, context).execute( ) ;Fails with this:
"javax.script.ScriptException: sun.org.mozilla.javascript.internal.EvaluatorException: Java constructor for 'uftestjs' with arguments 'number,javax.script.SimpleScriptContext' not found."
Obviously, no conversion is possible with context (javax.script.SimpleScriptContext to com.genexus.ModelContext).
There is some way to reference de original context, by the object Id??? or something like that???
Thanks in advance for any replies!!!
Greetings from Chile. (I hope you can understand my english!)

Hi
Well, since this topic is about java programming I think the place is right here.
(I use some tricks to embed java statements in genexus objects...)
I will try to get some help at Artech (GX) on how to build something... to get the conversion needed.
But they are not focussed on support this kind of questions.
Anyway, I want to know: do I can to reference an object by the objId?
I want to code something like this:
com.genexus.ModelContext context =
(com.genexus.ModelContex)getTheObjectFromTheJVM(theObjectId);(powered by google translator, ha!)

2 TopLink Java Object from Table to be used in single selectOneChoice

Hello everyone, can I ask for help on how to solve my problem....
Here's my scenario, I have 2 tables namely tblCollege and tblCourse, they are related through tblCourse.CollegeCode = tblCollege.Code.
I use the jdeveloper wizard using TopLink -> Java Object from Table to add these table to my project. I created an EJB Data Control so that I can use them to my Userinterface using ADF Faces.
What I really want to do is that I need to have selectOneChoice component displaying:
tblCollege.Name + tblCourse.Name, and it should have a value of tblCollege.Code + tblCourse.Code,
so for example in my
tblCollege:
Code---------Name
1---------------Science
2---------------Music
tblCourse
Code-------Name-----------CollegeCode
1-------------Biology----------1
2-------------Computer-------1
3-------------Guitar------------2
what I want in my selectOneChoice is like this:
value----------display
1-1--------------Science-Biology
1-2--------------Science-Computer
2-3--------------Music-Guitar
I'm a little stuck on how I'm going to that. Thanks.

Bawasi,
I see a couple of angles of attack, but this really depends on the technologies involved. If you are using ADF Bindings in combination with ADF Faces then you need to shape the data at the entity level. If ADF Bindings are no the in equation, you can take a less aggressive approach and shape the data in a managed bean. What is not clear to me is the end-to-end use-case. I see the read-only (i.e. how to get data to the drop box), but I am
not certain what attribute on an entity you are attempting to set. Are you trying to set the course for the current user or for a master schedule? Finally, notice that the final shape of your data set shows a unique combinations, you could increase the performance of your use-case and ease of development simply by denormalizing your schema.

How to instantiate a java object (using JNI)?(n'more)

hey bschauwe, thanks for your last post, you were guessing but your 4th guess was right on the money of how id like to do it.
"4. An alternative way to return data to java from C is to instantiate a java object (using JNI), then use JNI to call that object's setters, then return the object at the end of the C routine."
I know now how to get the object's setters, I am just unsure how to instantiate a java object from the native C code using JNI. Also you said to returnt he object at the end of the c routine, that is just a good ol' return statement right? no other functions to release memory or anything are needed? So basically it would be something like:
JNIEXPORT jobject retObj JNICALL Java_AbfaRegion_getJSourceData
(JNIEnv *env, jobject thisObj)
        //instantiate the java object on retObj????
        //call setters with values from the c structures...
        //return retObj??? no other memory releasing needed?
}Thanks again for all your help,
Shane

K sounds straight forward enough, the index in my book had nothing on <init> and I wasnt aware of the NewObject call. So my final (well for demonstration purposes) code should look something like:
JNIEXPORT jobject retObj JNICALL Java_AbfaRegion_getJSourceData
(JNIEnv *env, jobject thisObj)
     jclass clazz;
     jclass clazzTemp;
     jmethodID mid;
     jint val;
     jobject tempObj;
        //first instanciate the object
     clazz = (*env)->GetObjectClass(env, retObj);
     mid = (*env)->GetMethodID(env, clazz, "<init>", "()V");
        //Get Object
     tempObj = (*env)->NewObject(env, clazz, mid);
        //get Class reference to instantiated class
     clazzTemp = (*env)->GetObjectClass(env, tempObj);
        //Start calling setters to set the object up.
     mid = (*env)->GetMethodID(env, clazzTemp, "SetHeight", "(I)V");
     (*env)->CallVoidMethod(env,tempObj, mid, struct->myHeight);
        //set more members ...
        //return the object back to java with its members filled out.
        //before returning do I need to call (*env)->DeleteLocalRef(tempObj); ??
        return tempObj;
}So is this how i do it for a function that is nativly defined as:
public native JSources getJSourceData();?
if this is right, then im cooking, and cannot thank you enough!

How can you move the objects from one server to another?

how can you move the objects from one server to another?

Hi,
Collecting objects for Transporting
1. rsa1->transport connection
2. left panel choose 'object type', middle panel choose 'infocube' and 'select objects'
3. then choose your infocube and 'transfer'
4. will go to right panel, choose collection mode 'manual' and grouping only 'necessary objects'
5. after objects collection finished, create request
6. If they are $TMP, then change the package.
7. When you click the Save on the change package, it will prompt for transport. Here you can provide an existing open transport request number, or if you like here itself you can create a new one.
8. You can check the request in SE09 to confirm.
Releasing Transport Request
Lets say you are transporting from BWD to BWQ
Step 1: In BWD go to TCode SE10
Step 2: Find the request and release it (Truck Icon or option can be found by right click on request #)
Note: First release the child request and then the parent request
Steps below are to import transport (generally done by basis )
Step 1: In BWQ go to Tcode STMS
Step 2: Click on Import queue button
Step 3: Double Click on the line which says BWQ (or the system into which transport has to be imported)
Step 4: Click on refresh button
Step 5: High light the trasnport request and import it (using the truck icon)
Transport

(how) can I access Java APIs from web-page-hosted JavaScript?

Can I access Java APIs from a web-page via JavaScript if I have a JRE installed on the client machine? And if so, how?
Thanks in advance for your time and consideration.

John L. wrote:

And if so, how?As far as I can remember that was actually possible in the very first versions of Netscape because Netscape really wanted to pretend Javascript and Java were meant to be used together. But they soon removed that functionality. Can you guess why?
Because people were using the File/IO classes to easily steal or remove files on the harddrive, among other such niceties. You do NOT want to have such control from a web application. People will abuse it.

Can we call java jar from ODI?

Hi All,
Can we call java jar from ODI? if yes please suggest how?
Regards,
Satish

This is an excellent article from Uli.
One reason, I dont like this approach is that is mandates to copy the .jar file to the driver folder and restart the agent.
Think of a scenario where there are several developers in love with Java and want to place the jars in the drivers directory.
This is a maintenance nightmare for the admin and would clutter up the drivers directory.

I can't read a Object from file, Please help me

i want to write a Object into File. this is code of Object
class objStoreCus implements Comparable, Serializable
String customerID = new String();
String customerName = new String();
String customerEmail = new String();
objStoreCus(String cusID, String cusName, String cusEmail)
customerID = cusID;
customerName = cusName;
customerEmail = cusEmail;
objStoreCus(){}
public int compareTo(Object o)
objStoreCus oS = new objStoreCus();
oS = (objStoreCus)o;
return(customerEmail.compareTo(oS.customerEmail));
private void writeObject(ObjectOutputStream s) throws IOException {
s.defaultWriteObject();
private void readObject(ObjectInputStream s) throws IOException, ClassNotFoundException {
try
s.defaultReadObject();
}catch(IOException ie){throw new IOException();}
catch(ClassNotFoundException cnt){throw new ClassNotFoundException();}
And I was wrote above Object into File by this code :+
FileOutputStream fos;
ObjectOutputStream oos;
FileInputStream fis;
ObjectInputStream ois;
public void writeObjToFile(objStoreCus obj)
try
fos = new FileOutputStream("Exrcise3.ex3", true);
}catch(FileNotFoundException fnfe){}
try
oos = new ObjectOutputStream(fos);
//ghi doi tuong vao file
oos.writeObject(obj);
//dong stream
oos.close();
fos.close();
}catch(IOException ie){}
But i can't read above Object from file. allway have a Exception occur "StreamCorruptedException".
this is code read Object form file :
*parameter is ArrayList will be store Object from file.
public void readObjFromFile(ArrayList al)
try
fis = new FileInputStream("Exrcise3.ex3");
}catch(FileNotFoundException fnfe){}
try
ois = new ObjectInputStream(fis);
while(true)
try
objStoreCus osc = new objStoreCus();
osc = (objStoreCus)ois.readObject();
System.out.println(osc.customerEmail);
}catch(Exception e)
e.printStackTrace();
//System.out.println();
break;
ois.close();
fis.close();
}catch(IOException ie){}
}

Problem lies in
os = new FileOutputStream("Exrcise3.ex3", true);
You are trying to append to that file, You should always use new file to serialize objects.
os = new FileOutputStream("Exrcise3.ex3");
Try with above line.

Accessing java objects from within javascript

What do you mean by accessing Java objects? Do you mean interacting with an applet via JavaScript? Something else?

How we can remove one authorization object from multiplt roles

How we can remove one authorization object from multiplt roles

> Correct me if I am wrong !!
O.K., Here I go
> But if the object is maintained in SU24 and if you use Expert mode for generation of the role then again those objects may be pulled.(make sure you never use expert mode once you delete the objects)
Actually using expert mode and choosing 'edit old status' is the only way to avoid objects being 'pulled in' after menu changes.
> As jurjen said, you may download the tables and instead of deleting the object from the excel sheet, change the value of the object in column "DELETED" = X, by doing this only the objects get inactivated(but remain in PFCG).
I am not speaking of downloading tables but about downloading roles from PFCG. This will not get you a spreadsheet but a flat textfile. If you whish to set the object status to deleted you'll have to swap the space on position 207, right behind the 'U, S, G' flag, with an 'X' for all corresponding lines.
