Creating an applet instance

Hi
I am using Schulmberger Smart Card Tool Kit in order to create applet and applet instances.
I have created the applet inside the card but I couldn't create an applet instance. Because when I am going to create the applet instance by using the software it asks the install parameters. Still I don't know does it ask the parameters to call the method
// Install method
     public static void install(byte buffer[],short offset,byte length){
     // create a CryptoTest applet instance
     new CryptoTest(buffer, offset, length);
     } // end of install method
How should I give such parameters. Please reply me soon
If you can give me an example, That is perfect
Thanks
Best regards

Normally installation parameters are just passed to the Applet itself. It can evaluate it in the install method. The system specific parameters may be used by the OS to set minimum memory limits. What install parameters are required by your smart card OS, you should find in the data sheet or contact Gemalto customer support (Schlumberger --> Axalto --> Gemalto).
For reference check GP 2.1.1 card specification, 9.5 INSTALL Command, 9.5.2.3.6 INSTALL [for load] and INSTALL [for install] Parameters, Table 9-36: Install Parameter Tags

Tracking applet instances

I have an applet, and I want to support multiple instances of the applet running in the same browser.
This is easy: just make sure that the applet object is encapsulated properly - no ugly globals which aren't shareable.
However, the applet needs to use classes which create Threads and then perform callbacks into the main applet code. These callbacks are unfortunately static methods, even though the different applet instances need to handle them differently. The obvious solution would be to modify these classes, but they are binary only.
I had this working for Netscape 4 and Internet Explorer using Microsoft's JVM, by calling...
Thread.currentThread ().getThreadGroup ()...and maintaining a table mapping this object reference to a context object which could contain the information needed by the callback routine. This works because both JVMs create a separate ThreadGroup for each applet instance.
Sadly, it seems the Sun Java Plugin used by Netscape 6, most other browsers, and increasingly many installations of IE, puts all applet threads in the same thread group, no matter which applet instance they belong to.
Have a look at http://www.omniconsumerproducts.com/~martin/applet_test/test.html to see the problem. The source is in the same directory on the server.
Does anyone have any other solutions? I need to be able to get something globally that is unique to an Applet instance. I tried ClassLoader but all the browsers I tried use the same ClassLoader for different instances of the same applet. (Except for Netscape 4 if you shift-reload, but that's another story.)
The optimal solution would be if Applets could create their own child ThreadGroups, but they can't for security reasons (even though child ThreadGroups inherit all the restrictions of the parent).
Any ideas?

Are the threads created by the library doing anything time consuming? If not, then you can make sure that the library function that create the threads will not be called before the previous thread created by the function ends. Here is some pseudo code to show the idea. Since this is a design hack, it may not fit in your case though.
I tested the Mutex class, so the remaining code may have some error. Howerver, it should make the idea clear.
Lets assume you call a library function with two Object argument and the library calls back a static method someCallBackMethod in a new thread.
from your applet Foo you will do something like this,
class Foo extends Applet {
static LibraryAdapter la = new LibraryAdapter();
public void someMethod() {
la.call(this, someObject1, someObject2)
public static someCallBackMethod() {
Foo foo = la.getActive()
foo.doneWithActive();
}//Foo ends
class LibraryAdapter implements Runnable {
Queue queue = some thread safe queue implementation
private Mutex fetch = new Mutex();
private Mutex queueMutex = new Mutex();
public LibraryAdapter() {
new Thread(this).start();
public void call(Foo caller, Object arg1, Object arg2) {
queue.enqueue(new InvokationData(caller, arg1, arg2));
queueMutex.notifyX();
public Foo getActive() {
return queue.front().caller;
public void doneWithActive() {
queue.dequeue();
fetch.notifyX();
private class InvokationData{
Foo caller;
Object arg1;
Object arg2;
... constructor
public void run() {
while(true) {
fetch.waitX();
queueMutex.waitX();
InvokationData data = (InvocationData)queue.front()
... interact with library with data
}//main loop ends
}//run ends
}//top level class ends
public class Mutex{
private Object m = new Object();
private int wtc = 0;//waiting notify call counter
private int encc = 0;//extra notify call counter
public void waitX() throws InterruptedException{
synchronized(m){
if(encc > 0){
encc--;
}else {
wtc++;
try{
m.wait();
}catch(InterruptedException ex){
wtc--;
throw ex;
}//else ends
}//sync ends
}//waitX() ends
public void notifyX() {
synchronized(m){
if(wtc == 0){
encc++;
}else{
m.notify();
wtc--;
}//sync ends
}//notifX ends
}//Mutex ends

Create Value node instance from structure at runtime

Hi,
I have a requirement where an internal table is given with some details.
Now I need to add each row of this internal table as one entity into a collection.
For this I need to create value node instance for each entry of the table and then
lr_collection->if_bol_bo_col~add( lr_entity ).
this to add to the collection.
Please tell me how to convert this one row of this table into entity.
Regards,
pooja

Try it like this:
DATA: lt_data type table of ty_line.
DATA: ls_data type ty_line.
For the value nodes we need an data object
DATA: lr_line_ref type ref to ty_line.
The value node which should be added
DATA: lr_value_node type ref to cl_bsp_wd_value_node.
First create the reference structure
CREATE DATA lr_line_ref.
*Loop over you itab
LOOP AT lt_data into ls_data.
Create the value node based on the ref line
CREATE OBJECT lr_value_node
EXPORTING iv_data_ref = lr_line_ref.
Now set the data from the internal table
lr_value_node->set_properties( ls_data ).
Now add the created value node to the collection
lr_collection->if_bol_bo_col~add( lr_value_node ).
ENDLOOP.

Schedule Webi (and Crystal) report without creating a new instance

Hi all,
I'm looking for the way to not create a new instance of the report when we schedule a report? Is it any actions on the InfoObject object? Or is it just impossible to do?
Thanks in advance !
Edited by: jerome.vervier on Nov 21, 2011 11:40 AM

Hi,
With regards to your query, whenever a report is scheduled an instance of it will be created.
Therefore, it is not possible to schedule a report without creating an instance.

How can i create a new instance on unix

Hi,
How can i create a new instance(instance only) on UNIX and how can i mount my database with this new instance.

If you simply create a pfile and startup nomount with it, then -in theory- you have an instance running ( this method is used e.g. for restoring a rman backup )
2) You can't. Database files are bound to a certain instance. What you can do is recreate an instance with e.g. a different name, using the scripts generated by a 'alter database backup controlfile to trace;' command

How do I create a second instance of oc4j in a standalone enviroment

I am using OC4J standalone to deploy a sparql endpoint using jena, joseki, and the oracle jena adaptor. OC4J is running on the same server as my DEV and QAR databases. The current instance of OC4J is using a data source called "OracleSemDS" to connect to my DEV database. We are now ready to migrate the endpoint to QAR. As I was setting up the QAR endpoint, I discovered the the jena/joseki tools are hard-coded to use the "OracleSemDS" data source. Therefore, I cannot have 2 endpoints running in the same OC4J instance where one points to DEV and the other points to QAR.
Therefore, I need to create a second instance of OC4J that specifies QAR as the "OracleSemDS" data connection. Can someone tell me how to do that?
Thanks,
Phil

Thanks,
Philgday Phil -- Melli Annamalai from the Oracle Server PM team pointed me to your question. I was an OC4J Product Manager before we bought out BEA and I swapped over to WLS -- so I have some information below that hopefully is of assistance to you.
Since you are using OC4J standalone, the simplest way to get a second instance, is to just clone the existing, whole directory structure of your working OC4J instance into another directory, and configure/run it from that directory. To map the OracleSemDS to another target (QAR) you change the data-sources.xml file in the second instance. If you want to run them concurrently on the same server, you'll need to change the ports in the second instance so they have unique values: default-web-site.xml, rmi.xml, internal-settings.xml, jms.xml. These additional ports can be specified on the command line as a Java property string, albeit this is not a documented nor supported feature. See http://buttso.blogspot.com/2007/02/specifying-oc4j-standalone-ports-from.html for more information.
Now as an example, assuming you have your OC4J you want to clone in the dev directory, and now want to create a second instance of OC4J in qar, I'd do this:
cp -rp dev/* qar
cd qar/j2ee/home/config
vi data-sources.xml
(edit any other files if needed to alter ports) ...
cd ..
java -jar oc4j.jar That should work, and should create the second instance using the current configuration (ie dev) as its basis (including deployed apps). Of course, you'll need to manage them independently from here as they really are just two separate OC4J standalone instances.
Now what else you could potentially do is to create a secondary configuration file subset only which only changes the necessary files to support running the second instance. In this case, you'd make a copy of the j2ee/home/config/server.xml, j2ee/home/config/application.xml and j2ee/home/config/data-sources.xml files, renaming them to qar-server.xml, qar-application.xml and qar-data-sources.xml.
Then do the following:
1. In qar-server.xml file, you'd change the global-application application to point at qar-application.xml instead of application.xml:
<global-application name="default" path="qar-application.xml" parent="system" start="true" />
2. Change qar-application.xml so that it used the qar-data-sources.xml file:
<data-sources path="qar-data-sources.xml" />
3. Change qar-data-sources.xml file so it points to the qar database target.
4. Start OC4J, telling it to use qar-server.xml instead of the default server.xml
D:\java\oc4j-10135-prod\j2ee\home>java -jar oc4j.jar -config config/qar-server.xmlI think you could run into some concurrency problems if you try and run the two instances simulataneously, but in general it should be OK I think if you run them separately.
Another solution here is look at how the application specifies/uses datasources. The hard coding of the data-source name into the applicaiton via a direct JNDI lookup works, but restricts the flexibility you as a deployer/administrator has.
If the application used the Java EE resource-ref approach to look up and use the datasource, then the actual JNDI name of the datasource the application uses it totally abstracted from the actual physical name of the datasource that is created on the container -- so you'd have DEVDS and QARDS as physical datasources configured and running on OC4J -- and what happens is that as you deploy the application, you essentially map its lookup and use of OracleSemDS (which would need to change to a java:env/ namespace) to the physical datasource you want it to use (DEVDS or QARDS for example). You can easily alter this post deployment by changing the generated orion-application.xml file to point at the alternate physical datasource. Following that, you can also create separate deployment plans which map the app to the different datasources, then feed this in with the deployment operation so that the correct mapping to either DEVDS or QARDS is done during the deployment process.
I don't know what scope you have to change the application so the above may not be possible -- you'd need to change the lookup code so that it uses the Java EE reference model and change the meta-inf/application.xml to add the corresponding resource-ref entry which declares the logical datasource name that needs to be mapped on deployment.
Another approach here may be to use an application embedded datasource, where you put a data-sources.xml file into the application archive itself (along with an orion-application.xml file which references it) whereupon at deployment time, a datasource specific to the application will be created. In this manner, you'd have say two copies of the same application to deploy (DEV, QAR) which contain different data-sources.xml file. From memory, each application will have its own JNDI namespace so their datasources can co-exist with the same names, with application level data-sources overriding server level ones. Since you'll most likely want to keep the same context-root for the web modules (which has to be unique per server) you'll generally need to run just one of the applications at a time. I'd do this like this: deploy one, stop it, deploy the other, stop it, then start only the one you need to test. In that way, you'll have one copy of the application running (either DEV or QAR) and one datasource definition running within it.
Here's some documentation links to get you going:

Problems when creating a new instance of an Input parameter for a REM

I am working in a small demo which calls a Remote Enable Function Module in order to read data from the back end system. Since the function module I need to call ("BP_BUPA_SEARCH_BY_USER") is not Remote Enable I created a copy of it and made it Remote Enable ("Z_BUPA_SEARCH_BY_USER"). I have created the model within webdynpro without any problems but when my application reaches the line where I create a new instance of the object Z_Bupa_Search_By_User_Input (see below the source code), just before to call the remote function, the application stops there. I have exactly the same code in another bapi calls and it works fine. I am wondering if my problem has anything to do with the fact the function module i am calling is the function module I created. Any advice is very welcome.
Regards,
Diego.

How to create an applet in a JDestopPane?

hello i would like to create an applet (JApplet) in a desktop (JDesktopPane).
i have to put the applet in a JInternalFrame so i can move and resize the window around.
indeed i can have several applets in the JDesktopPane.
it would be more powerfull than viewing it in a web navigator.
more i want to load an applet from its web site from its jar file.
i know that from a html page, you have to tell the navigator where is the jar file with the "archive" tag; the "CODE" tag is the name of the class file not the path to the package like my.package.myclass !
can i put my.package.myclass instead of myclass.class in the "CODE" tag?

PS2013 - When creating a new instance of Project Server hangs in 'Waiting for resources' status

Hi,
I have one instance of Project Server 2013 fully operational and I tried to duplicate the instance to make some tests. As I know the issue of using the same Content Database of Project Server in the same Server Farm, I used the powershell backup/restore/dismount
and mount the content database to change the site IDs to avoid index duplication. The Project server database was a regular SQL backup and restore in another database.
I created a new Web App in the port 90 as show below.
Then I included the Content database of Project Server as separated DB from SharePoint for this new SharePoint -acme90 and I tried to create the new instance. The creation hanged in "Waiting for Resources" status.
To make another check excluding the reuse of the SharePoint-80 I tried to create another instance both in the SharePoint-80 where is the working instance and in the SharePoint-90, everything default and again they all hanged in Waiting for Resource.
If I try to create the instance using PowerShell I got the following error:
PS C:\Users\epm_setup> Mount-SPProjectWebInstance -DatabaseName Test_EPM -SiteCo
llection http://acme02/epm -Lcid 1046
Mount-SPProjectWebInstance : Cannot find an SPSite object with Id or Url:

   ountPwaInstance
All SharePoint and Project Server services are running, all App Pools and sites are started at the IIS. I could not find a hanging timer job.
I cannot stop the hanged process or dismount the instances using Powershell since no instance created.
How should I solve the hanging status of creation of the instance? As they are in Hyper-V I can go back using one snapshot.
Thank you.
Best regards, Ricardo Segawa - Segawas Projetos / Microsoft Partner

Hi Eric,
Thank your for your interest in this case.
I checked for running and crashed PWA jobs and deleted all of them just after restoring the snapshot and tried to create the new instance in the new web app in port 90 (besides the existing and working instance in port 80), but again it hanged in "waiting
for resources". There is not any timer job hanging, no error in event viewer or in log. So the error is well before working with cloned dbs.
Answering your questiion, I am working all on 2013. My intention is backup one instance of the port 80 and copy to the instance of port 90, changing of course the url and the index of the content db of SharePoint. The process I used was:
Create a new web app in port 90, creating a new SharePoint_Content_2 on a
http://server:90 site.
Created the top level site called Portal using the Team Site template.
Create a new content db for new instance of Project Server named EPM_Content_2 using Central Admin.
Backup content db from port 80 instance of Project Server and restore to this EPM_content_2 using PowerShell cmd.
Dismounted and mounted this Project Server content db to create new index for existing sites to avoid index conflicts.
Backup the Project Server DB from port 80 using SQL backup and restored as ProjectWebApp2 db for port 90 instance.
Tried to create a new instance of Project Server
http://server:90/pwa on web app of port 90 using the ProjectWebApp2 db and using the same app pool of the other instance. But as in the previous case, it hang out in "Waiting for resources".

Instead of creating multiple Instances I want to create only one Instance.

Hi Everyone
Good morning, How are you.
I have a requirement to transfer files from one location to another location, I am able to do this successfully using FTP Adapters.
I have some Issues please help any one.
1) When I deployed my process it is creating one instance for one file transfer, Suppose If I have 50 files in my Get
directory, After deploy the process 50 instances are creating and 50 Email generating saying files are not tranfered successfully.
Instead of creating 50 Instances I want to create only one Instance.
2) When files are not transferd it will fire error mail saying that not success (I want to display all file names(not tranfered files) in my mail , i.e whatever files are not tranfered, need to diplay in mail).
3) And I am not able to transfer 0 size files, But in BPEL Console Instance is creating for 0 size file also and I am getting Email for success... and In put directory 0 size file is not showing. (Instance is creating and Success Email coming but file is not exists in Put directory)
Please help me.
