Using Oracle XQuery from Java Only

Hi,
I am interested to use the Oracle XQuery implementation to run on XML files only - no databases! Is it possible to do? Which jar file I need in JDeveloper to do that?
Does it support the latest XQuery version?

Our usecase is this :
1. There would be some BPEL template files in XML with some placeholders for runtime parameters and XQuery FLWR expressions.
2. At runtime, from Java, we would like to substitute those placeholders by runtime parameter values - would like to use the XQuery Java APIs to do that - see something similar available in Saxon XQuery parser.
Is it possible from Java using Oracle technology?
Thanks

My knowlege about COM is rather bad.
Does anybody did this bevor and
-> can say me, if it is correct, that i only got a utility-class (so how will i use it from the client ?!)
-> has a example for using Excel / Word from Java in bea weblogic
-> has a example for using Excel / Word directly in a client (not via rmi)

Use a scanner from Java

Hi all!, someone knows about an API that let me use a scanner from Java?
without programing JNI code.
thks in advance!.

The Java Twain package from http://www.gnome.sk does exactly what you need. You do not have to bother about jni, you can get an image from the scanner directly from your java application.

Patches 7446163 y 6851110 in order to use Oracle Text from UCM

Hello, we have Oracle Enterprise Edition 11.2.0.1 on AIX 6.1.0.0 (64 bits). The client want to use Oracle Text from Universal Content Management, he told me about install the patches 7446163 y 6851110 in order to enable Oracle Text from UCM. I reviewed in Metalink but the readme said that those patches are for Oracle 11.1.0.7. That version (11.2.0.1) include already those patches or those are necessary for we can use the funcionality of Oracle Text from Universal Content Management? I reviewed the components installed on database and the Oracle Text is installed and active.
Thanks for your help.
Sincerely,
Ruben Nieto
DBA

Hi
Oracle DB usually would be installed with Oracle Text enabled (the db side) . To use the features for this we need to have OracleText component enabled on UCM which as you mentioned is already installed and enabled on the ucm server .
If both the above conditions are already met then you would not need to install any further patches.
Let me know if it is fine on db and ucm .
Verify that Oracle Text is enabled on db by executing the following query :
select comp_name, status from dba_registry;
It should return the the following result : Oracle Text VALID
To verify if the component for UCM is installed then you would need to check Administration - Configuration for <instance name> - Enabled Components
Thanks

Passing SQL-Parameters to Oracle-Reports from java

hello,
i want to write an application in the following way:
on a java-frontend an user can select values for different
parameters. these values should be to transferred to the sql-
query of the reports rdf file. what is the syntax of an
parameter passed from java to oracle reports.
does this work with runtime.exec()... ?
does anybody have an example.
any help would be very appreciated.
greetings
Thorsten Lorenz

In order to pass the parameters to report rdf, you can create user parameters in the oracle report builder, hook up the parameters with query. For example, you can create user parameter P_DEPTNO, then create a sql query: select * from dept where deptno = :P_DEPTNO. When you run this report, you give P_DEPTNO=10 as parameter, the rdf will generate report that only prints out department 10's information.
Once you have this kind of report created, you have several ways to achieve what you want.
1. use rwrun60. In your java program, you can invoke rwrun60 via runtime.exec(cmd) where cmd = rwrun60 report=dept.rdf userid=scott/tiger@orcl destype=file desformat=pdf desname=dept.pdf p_deptno=<value_from_java_app>
2. similarly, use rwcli60. the cmd would be:
cmd = rwcli60 server=repserver report=dept.rdf userid=scott/tiger@orcl destype=file desformat=pdf desname=dept.pdf p_deptno=<value_from_java_app>
3. use rwcgi60. Instead of using runtime.exec, you should use java URL object to run the report in the web environment.
option 2 & 3 takes advantage of powerful functionality of reports server, and it is much more scale than option 1.

Requirement to be fulfilled using PI 7.3 Java only installation

Hi Experts,
We have a requirement depicted as below and need to confirm if the same is possible in PI 7.3 JAVA only
installation where there is no possibility of using ccBPM.
Step 1. System A sends web service request to PI,
Step 2. PI sends the request to System B which is a web service call
Step 3. System B sends response back to PI
Step 4. PI gets the response from System B, this response needs to transformed and mapped and sent to System C web service request.
Step 5. The response from System C needs to be sent back to System A which initiated the call.
Please give a thought based on your experience and expertise if this is possible; given the limitation of java only installation which is without ccBPM.

On making call to Oracle procedures from Java, Value becomes null on oracle

We are using some user defined Oracle data types in my Java/J2EE application
and some of them are Oracle collections(ex. VARRAY).
We are making a call to Procedures/Functions from Java, there are some
parameters of user defined data types declared in the
procedures/functions, from java the values are properly setting to these
user defined data type parameters and sending to Procedures.
We are not getting any exception at Java side and Oracle side and values
are becoming blank/null at oracle procedure side for the parameters of
user defined data types.
But when do the count of collection of user defined data type then it is
properly giving the size of collection(VARRAY).
When we are trying to read the values from the collection(VARRAY) it is
giving blank/null value and there is no exception.
Please let me know if you have any suggestion on this?

user7671994 wrote:

Using Oracle Wallet for Java connection

Hi,
Can anyone tell me how to acces the Oracle wallet from my Java application without using the thin or oci drivers?

No answer was found for this, we ended up using an OCI driver for the connection to the wallet. Code (in java) was as follows for reference:#
private static Connection walletconn() throws Exception{
String url = "jdbc:oracle:oci:/@DATABASE";
OracleDataSource ods = new OracleDataSource();
ods.setURL(url);
Connection conn = ods.getConnection();
return connl;

Call a C++ services using an uuid from java

I need to call a C++ services which is using the UUID for RPC. The interface is having the UUID. The previous client program is also in C++, they have used RpcBindingFromStringBinding(UUID value, .,.,.) to call the interface. Right now I need to call this service from Java using the UUID. Can anyone help me in it.

Passing the UUID should be the easy part, the tricky bit is performing an RPC from Java to C++. How are you doing that? Once you sort that out, passing arguments should be straight forward.
Note: Java's RMI only works between a client server running RMI. To connect to C++ server, you need to use a Java client library which is compatible with your C++ server.
If you still don't know how to perform the RPC call, I suggest you contact the people supporting the C++ program as they should know how RPC calls are made currently. If they don't know, it is highly unlikely we can guess a solution unless you are willing to change the C++ server to use a known RPC mechanism.

Using Inbound IDOC from Java system creation of Outbound delivery

Dear Experts,
The scenario we are having is really very interesting. Hopefully its a good learning for me and also for others also.
The scenario is,
After sales order creation the details will be sent to one Non SAP system (Java) for performing some tasks related to forwarding agent decision, shipping date and etc. Once the details are finalized in that Java system then, the details needs to be transferred to SAP as "Inbound IDOC" process. For this proposed to use the SAP Jco middle ware.
Once the details transfered from Java system to SAP then, the outbound IDOC needs to get generated automatically. Assuming the stock for that sales order line item is available. Also one more complexity is, our client is using custom transaction (ZVl10C) for delivery creation.
Now Query is,
1. Which IDOC, message type and Functional module needs to be used for creating the delivery automatically..??
2. As per assumption, stock of that sales order line item should be available. Due to some business reason the stock was removed during inbound IDOC transfer then, what will happen to the IDOC..?. How to avoid this situation..??
3. As we told we are re going to use SAP Jco b/w SAP & Java system. In this case, how the data will get transfered from Java system to SAP..?
Thanks in advance for the replies I am going to get
Regards,
VEL

Using ExecutorService class from java.util.concurrent package

Dear java programmers,
I have a question regarding the ExecutorService class from java.util.concurrent package.
I want to parse hundreds of files and for this purpose I'm implementing a thread pool. The way I use the ExecutorService class is summarized below:
ExecutorService executor = Executors.newFixedThreadPool(10);
        for (int i = 0; i < 1000; i++){
            System.out.println("Parsing file No "+i);
            executor.submit(new Dock(i));
        executor.shutdown();
        try {
            executor.awaitTermination(30, TimeUnit.SECONDS);
        } catch (InterruptedException ex) {
            ex.printStackTrace();
        executor.shutdownNow();However, the code snippet above creates all the 1000 threads (Dock objects) at once and loads them to the executor, and thus I'm worrying about memory leak. I haven't tested it on 1000 files yet but just on 50 small ones, and even if the program prints out "Parsing file No "+i 50 times at once, it executes normally the threads in the background.
I guess the write way would be to keep the number of active/idle threads in the executor constant (lets say 20 if the thread pool's size is 10) and submit a new one whenever a thread has been finished or terminated. But for this to happen the program should be notified someway whenever a thread is done. Can anybody help me do that?
thanks in advance,
Tom

Ok I found a feasible solution myself although I'm not sure if this is the optimum.
Here's what I did:
        ExecutorService executor = Executors.newFixedThreadPool(10);
        Future<String> future0, future1, future2, future3, future4, future5, future6, future7, future8, future9;
        Future[] futureArray = {future0 = null, future1 = null, future2 = null, future3 = null, future4 = null, future5 = null,
        future6 = null, future7 = null, future8 = null, future9 = null};
        for (int i = 0; i < 10; i++){
            futureArray[i] = executor.submit(new Dock(i));
        }I created the ExecutorService object which encapsulates the thread pool and then created 10 Future objects (java.util.concurrent.Future) and added them into an Array.
For java.util.concurrent.Future and Callable Interface usage refer to:
[http://www.swingwiki.org/best:use_worker_thread_for_long_operations]
[http://www.particle.kth.se/~lindsey/JavaCourse/Book/Part1/Java/Chapter10/concurrencyTools.html]
I used a Future[] Array to make the code neater. So after that I submitted -and in this way filled up- the first 10 threads to the thread pool.
        int i = 9;
        while (i < 1000){
            for (int j = 0; j < 10; j++){
                if (futureArray[j].isDone() && i < 999){
                    try{
                        i++;
                        futureArray[j] = executor.submit(new Dock(i));
                    } catch (ExecutionException ex) {
                        ex.printStackTrace();
                    } catch (InterruptedException ex) {
                        ex.printStackTrace();
            try {
                Thread.sleep(100); // wait a while
            } catch(InterruptedException iex) { /* ignore */ }
        executor.shutdown();
        try {
            executor.awaitTermination(60, TimeUnit.SECONDS);
        } catch (InterruptedException ex) {
            ex.printStackTrace();
        executor.shutdownNow();
    }Each of the future[0-9] objects represents a thread in the thread pool. So essentially I'm check which of these 10 threads has been finished (using the java.util.concurrent.Future.isDone() method) and if yes I replenish that empty future[0-9] object with a new one.
