What's the Java Class Type corresponding 2 projectGantt's SubTasks Accessor

Hi,
I expose my java class as data control, and use the data control as a projectGantt. I get problem when i try to set the SubTask Accessor.
I have a Fusion Web App, in the Model project, i write 2 java class: ( all the private fields has public gettors and settors which are omitted here)
1
public class GanttTask {
private List<GanttTask> _subTaskList = new ArrayList<GanttTask>();
2
public class GanttDataControl {
private List<GanttTask> _dataList;
I expose the 2nd class: GanttDataControl.java as a data control by right click on it and select _"Create Data Control "_ from the drop down list.
The data control creation is ok.
I Drag&Drop the +"dataList"+ from the data control as a projectGantt, and only finish the data binding in the _"Tasks"_ tab.
I run the page, the projectGantt shows ok with a FLAT(list) structure.
I try to set the binding in _"Subtasks"_ tab.
In the _"Subtasks Accessor"_ LOV, the +"subTaskList"+ appears in the LOV.
I select it and finish the binding below it.
I try to run the page again, the page cannot be showed and an error appears in JDeveloper:
<LifecycleImpl> <_handleException> ADF_FACES-60098:Faces lifecycle receives unhandled exceptions in phase RENDER_RESPONSE 6
oracle.jbo.NoDefException: JBO-25058: Definition subTaskList of type Attribute is not found in ViewDefGanttTask1_7.

i try to manually add the subTaskList from the data control to the page's "Bindings", it doesnt work.
I solve this problem by using VO & View Link. Add using AM to expose data control.
In the SubTasks dropdown list, I notice that, there is an additional SubTasks accessor which is the accessor that i defined in the View Link.
I use this accessor, problem solves!

If it does not work, create & use custom converters as mentioned in the above thread.

If i change the class to type (as someone said in a previous post)That would only work if you already put the bean in the session scope.

Only a type can be imported. com.database.contactDB resolves to a packageDo you have a package structure that looks like this:

com/database/contactDB/
Because that is what the compiler is saying. Though it may be thrown off by case (see below)
P.S. If you use the jsp:useBean you do not need the import statement which appears to be where the error occurs. (One of the things that makes JSPs so hard to debug is the fact that the error line in the generated java file as referenced above is never the same as the line in the JSP file).

And to be ultra clear - you did compile contactDB from a .java file to a .class file, and the class is called contactDB and not ContactDB correct? The class name is case sensitive and should be the exact same case in the useBean and import statements as in the real class name.

What is the best data type for wallet application?

Hi Friends..
I want to know what is the best data type for wallet application..
Assume that, i want to the Total of money saved digitally in Applet Wallet..
And then if there's any transaction the Total of money which saved digitally in Applet Wallet would be Subtracted or Added depends on how much money that spent or saved..
Which one is the best implementation of these scenarios :
1. I save the User ID and Total of money in the Java Card, and then if there's any transactions, it would be added or subtracted directly and then saved again in the Java Card
2. Or.. I save the User ID in the Java Card whereas Total of money in the Database, and then if there's any transactions, the ID would be read from the Card, and then select the Database based on that ID, and then Add or Subtract the money depends on how much money spent in the Transaction
Please help me regarding this
Thanks in advance

Hi,
Personally I would choose to store the total amount stored on the card. You could use two shorts (short[] perhaps) to store an integer (add more shorts to increase precision) and simply handle overflow your self. You could even look into using a third party library (or class) that treats a byte array as a big integer etc. There were some posts recently on floating point arithmetic that could be helpful for you since you will probably want to use decimals and JC does not natively support floats.

How to read the java class file to convert it in java.

hello all,
i m developing the java application which generated the java code from the java 'class file' .
Can anybody please help me, Is any java support for reading the class file? or how to know the class file format?
I know the application javad, jad, javap which is doing the same thing.
thanks for reply,

do you mean decompiling? there are tons of java decompilers available out there, what exactly are you trying to do here?

Where to keep the java class file which is being used from a form?

Hi,
Actually I am developing a form which has a bean area and the data will be displayed in the bean area in the form of grid. And I will register this form with apps and will run the from Oracle apps. I want to know that there is a java class file that is being refered by the form, where should this java class file be placed and is there any other places where any changes are required so that the form runs correctly from the Oracle apps and can find the java class file.
I am very thankful to each and everyone who will be able answer this question of my.

Is it possible to put the java classes of an application and run?

Hi All,
Please excuse me if this question seems meaningless / laughable.
We get java class files by compiling the source code with java compiler. To run the application, classpath can be set to the folder where the class files are stored and then run the main class.
Now the question is, is it possible to read the class files to RAM and then run the application. I highly appreciate your help.
Thanks in advance.
Chinnaswamy

You could
1.) copy the class files to a ramdisk
2.) write another class loader that deletes the class files after loading >them from ram
but all of this is probably not necessary.
What exactly would you like to achieve by doing this? Thanks, JoachimSauer.
The idea I have in mind is to first read and store the java class files in C/C++ code and then while running the C/C++ code, read & put the java classes into RAM and run the java application.
This way the decompilation problem can be alleviated for valuable java applications. ( I am not sure, this will work)
Another reason could be speed improvement. Classes in RAM is expected to make the application to run faster than when class files are in hadr disk
With regards
Chinnaswamy

"The java class is not found:" post clone

Hi.
I've just cloned an 11.5.10.2 environment from one AIX5.2 server running 9.2.0.7 to another server at the same AIX and RDBMS level.
After running the clone steps, the application was automatically started and I was able to access it via Self Service, forms, run concurrent requests etc - in short, I had a working system.
Now, however, when I try to stop or start the application using adstrtal.sh/adstpall.sh, I hit the following:
"The java class is not found: oracle/apps/ad/autoconfig/ServiceControl
Check logfile /data/testcomn/admin/log/TEST_ireaix2/05011011.log for details"
On the command line, when I call the line the script is trying to execute:
/usr/java14/bin/java -classpath "${CLASSPATH}:${JAVA_TOP}:${FND_TOP}/java/3rdparty/stdalone/xmlparserv2.zip" oracle.apps.ad.autoconfig.ServiceControl -e /oracle/testappl/admin/TEST_ireaix2.xml -u apps/<PASS> -m 2 -l yadda –debug
I'm able to bypass this particular error and some of the application processes do start but not all of them and obviously I still have an underlying Java/environment issue.
Any suggestions gratefully received.
Rgds,
Jes

I have imported .class file into CMC and trying to invoke the .class file by another java program from eclipse..When i tried to invoke the .class in cmc, i am getting an error msg, mentioned above. I thought there might be version conflict. So i changed the java complier version to 1.5 in my Eclipse. After that is done again i am facing the same problem.
Can anyone help me to resolve this issue?
Thanks in Advance.

i have installed BO SDK 3.1 , Service pack 3. It comes woth JDK 1.5 version. i have not done any chnages to it. I impoprted all the jar files related to BO into eclipse.
1) Actually, i am writing java code on eclipse. When i run code from the eclipse, it creates a session to cmc and creates folder structure what i need.
2) But the thing is, that code needs to run, when i import the .class file into cmc. The process how i imported the .class file to cmc.
Manage> Add> Program File-->Java (Check Box). In this way i added java class file from the eclipse workspace (class file from the bin directory).
3) So when i run the .class file externally by another java program or also when i log in to CMC and run that .class file, the instance shows sucess, but when i see the logfile i am getting an exception that which i mentioned above.
If my method is worng can you please let me know the stepts how to run java program in cmc.
Thanks in Advance

What is the Java Library Path?

Hi,
I have a Java package that I need to add to my computer. The instillation information that I received with this package is as follows:
* For this package to function, you must modify your java library path
(the "java.library.path" property) or you must copy <WInterface.dll> to
a directory that is already on that path.
My questions are
1). What is the java.library.path?
2). How do I determine what the path is for my computer,
3). And finally how do I modify this path?
Thanks for your assistance.

1) It is the list of paths to search when loading libraries.
2) That can be found out with this program:public class PrintLibraryPath {
public static void main(String[] args) {
System.out.println(System.getProperty("java.library.path"));
}3) By giving the java launcher the command line argument "-Djava.library.path=yourpath".

WHat is the best index type for non uniqueness / Varchar columns in SQL 2008 R2

Hello All Greetings,
Please help me here with my doubt,
in my table i have two columns about a million rows, it has about 20 columns in it, three columns with name as Period, Gender so most of the time these two columns use in where clause,
Gender will contain Either M or F , Period contains YYYY-Month (2013-December, 2013-August) etc so i would like to add a Index to these two columns so that in will increase the performance, so please let me know what type of indexes i need to add to
these columns in the table,
please note that only one time we will add data to the table which will take only 2 minutes but we query the table every day
so my question what is the best index type that i need to create on columns with non uniqueness values in the column.,
Thank you In Advance,
Milan

There is nothing whatever wrong with creating an index on a VARCHAR column, or set of columns.
Regarding the performance of VARCHAR/INT, as with everything in a RDBMS, it depends on what you are doing. What you may be thinking of is the fact that clustering a table on a VARCHAR key is (in SQL Server) marginally less efficient than clustering on a monotonically
increasing numerical key, and can introduce fragmentation.
Or you may be thinking of what you have heard about writing JOINs on VARCHAR columns - it is true, it is a little less efficient than a JOIN on numeric type, but it is only a little less efficient, nothing that would lead you to never join on varchar cols.
None of this does not mean that you should not create indexes on VARCHAR columns. A needed index on a VARCHAR column will boost query performance, often by orders of magnitude. If you need an index on a VARCHAR, create it. It makes no sense to try to find an
integer column to create the index on - the engine will never use it.
