Java API - finalize method for XmlResults

Hello!
I'm wondering why in DB XML Java code we have a finalize() method which invokes delete() method whereas we are supposed to invoke delete() method manually (according to the documentation). Is it ok if delete() method is invoked twice (it happens in case GC cleans up the XmlResults object) ? Can't we get some problems because of that?
Thanks,
Vyacheslav

Also you should note that Java actually makes no guarantees that the finalize() method is called, and it can frequently happen in practice that this is the case. For instance, the JVM usually doesn't bother calling finalize() on objects if it is shutting down, which can be disastrous for DB XML objects like Environment, XmlManager and XmlContainer, which need to clean up and write data to disk when they are closed. Read the [FAQ | http://www.oracle.com/technology/products/berkeley-db/faq/xml_faq.html#16] for more details.

MDM JAVA API SCA file for MDM 7.1 SP04

I need to download MDM JAVA API SCA file for MDM 7.1 SP04. When I added to the download basket through service marketplace it is looking for the approval process, just for the API file. I was able to get the other files though like webdynpro framework, change tracker. We haven't setup the Solution Manager yet. It might take a while. Meanwhile is there any other way to get the SCA file.
Thanks

Opened message with SAP and they have approved the download basket. Now able to download the sca file.

Java API - Editor class for an XML schema

Hi,
i am very interesting in Java API. I would like to make an editor class for an XML schema. (I will create XML files in the current project based on this XML schema.) What step's are require for this editor class?
Regards
Gabor

you can provide a schema when parsing an xml document in order to check for schema conformance, but that isn't going to affect your XPath queries at all. DOM content is never anything but strings.In the case of both dom4j/jaxen and the .NET runtime the values returned from XPath queries when a schema is provided are typed. So you get back numbers, dates, and booleans as well as strings. And for numbers you get correct comparisons so 20 > 1.i guess it's possible. i use schemas when parsing xml, and i've used xpath (infrequently), but i'm not sure that i've ever used them together in a way that i would see functionality like that.
FYI, you use http://docs.oracle.com/javase/6/docs/api/javax/xml/parsers/DocumentBuilderFactory.html#setSchema%28javax.xml.validation.Schema%29 to specify a schema while parsing with a DocumentBuilder.

Java API (web services) for exportMetadata and importMetadata

We ususally use WLST command : exportMetadata and importMetadata to export/import MDS. is there any corresponding web services or Java API avalaible for the similar purpose?
Thanks

Hi,
U can expose a EJB or a java class as a webservice in webdynpro and u can use it in webdynpro directly and if u want to use it through Portal u need to create proxies and do it.
U can go through this weblog which helps u in creating a Bean as a webservice.
/people/sap.user72/blog/2005/09/15/creating-a-web-service-and-consuming-it-in-web-dynpro
And u can expose the services created in XI also as webservices.

Finalize() method for newer JVMs

Hi,
Just a quick question on finalize() if that's ok. From memory the only time the developer should have to implement this method is when you want to do something with a system resource during garbage collection.
A finalize method should never have to worry about clearing object references etc? Correct?
I am 99.9999999999% sure on this.
I am looking at some old code here which contains some objects which implement the finalise method, I am trying to figure out why they did it.
Is there any obscure case (i.e. with weak references or something) where an object may have to clear object references in finalise?
Thanks in advance.

Even where you do want to do that (and it's rarely a good strategy except as some kind of backstop, since there's no guarantee you system resource related object will ever be garbage collected), I'd recommend using a PhantomReference instead. It's more controllable. You control what thread it's cleaned up on, you can pass references in a way that's dangerous in a finalize and you can discard it if (as should happen) the program explicitly closes it's connection with the resource.++agree: PhantomReference<TollBooth>

OIM - docs for Java APIs and methods, where are they?

Hello all,
I am having trouble finding the documentation for the various Java methods. I believe that with 9.0.3 there should be something available, but I can not find it.
thanks in advance
Kam

Sigh...
Ok, so the API docs are not included in the downloadable version of the docs, only in the live web version. Took me a while to find that discrepancy!
Furthermore the live web returns 404 broken links for them, but at least I managed to find them squirreled away on the Oracle Japan site.

Does WebDynPro have finalizer method for some ojects?

I need to create object pool with guaranteed call to destroy participated objects (DB Sessions) after end of some method execution,
or owning object release.
Does WebDynPro has such a method?
How to implement it?
thanks

OK, very thanks , that answer was presented on most seen place,
(not always seen).
what is unteresting - does it really guarranteed to be called?
Happen at all experiments - is not "guarranteed".
Are there any else ways?

How to start to work on MDM JAVA API by using webdynpro for java

Hi all
I have basic idea on MDM business package thru portal by using standard iViews.
now i am planning to work on MDM JAVA APIs by using Webdynpro for Java as UI.
1) can you please share the required documents on the same. how to start working on this by using MDM JAVA APIs in webdynpro for java
2) what are the JARs files are required and how to integrate those jar files into webdynpro for java application.
3) is there any SDN help on MDM JAVA API with webdynpro for java? . can you please send the link on the same.
4) can you please help by providing sample code on how to use JAVA APIs for retrieving,deleting,inserting and Updating the data in the database.
if anybody helps on the same then it is the great help to me.
points are always rewardable...
Regards
Suresh babu

Hi Suresh,
You can have the MDM JAVA API javadocs from the link
http://help.sap.com/javadocs/MDM/SP06P2/index.html
There you can see a package named com.sap.mdm.examples.The classes in it contains some examples using which you can start understanding the code.
You need to have MDM JAR files for it. And these JAR files to be used at build time can be added to the project thru :-
Right click on project-> properties->Java Build Path - > Add external JARs
At run time you can add them the reference in
Right click on project-> properties->web dynpro references->library reference.
Thanks

Oracle Spatial 10g R2 Java API

Hi All,
I have a JAVA tool said to be written for Oracle Spatial 10g R2 Java API which uses for example the class oracle.spatial.georaster.JGeoRaster. I have to port it to 11g R2. The tool is definitely written for an earlier version, because compilation fails on for example JGeoRaster.getProperties() method which is not present in the new API. For this new API I have a fine Javadoc documentation here:
http://download-llnw.oracle.com/docs/html/E11829_01/
I have searched for a similar one for 10g R2 but found only like
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14373/toc.htm
which misses the oracle.spatial.georaster package. Is there such a package and if so, where can I find docs for it?
thank you in advance, best regards: Balázs Bámer

Hi Balázs,
the GeoRaster Java API was first released with 11gR2. Your first link points to that, or this link:
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11829/toc.htm
your second link points to 10g Oracle Spatial Java API, which doesn't include any GeoRaster related API. your tool might have been developed based on the old INTERNAL georaster jar file, which is not supposed to be used by your java program. But if you do want the api doc, you can run javadoc or jdeveloper to find out the api from the old sdogr.jar file.

How to use the Public Java API

Is it possible to use the Public Java API to write a custom transformation in Java and use this in OWB. i.e. Say I have a Dateofbirth field in my source database and an Agegroup field in the target database, and I write a transformation in Java to take the Dateofbirth as an input parameter to the method and calculate the Agegroup e.g. 25-30, and return it from this method which then populates the Agegroup field in the target database. If so, how do I go about this?

Martin,
In general, yes you could... but you do not need to. You could use the UI to implement this requirement. The public Java API is there for you to manipulate metadata. How you implement your system, is independent of that.
The way you would go about the case you just mentioned... you would write the Java code, deploy it into the database, wrap it in a PL/SQL procedure or function, and call it from OWB.
Would this be a good idea...? I think no. Unless you have very complicated calculations that can only be performed in Java, I strongly encourage you use the PL/SQL language. Reason being: transformation will be much faster, because there is no need to translate PL/SQL into Java and back again.
Hope this helps,
Mark.

Java.lang.SecurityException when trying to execute Workflow-Java-API from Servlet

I'm trying to call some of the Oracle Workflow-Java-API Classes/Methods from a servlet running on OC4J.
The following Code-Sample is exactly copied from the WFTest Example shipped with Oracle-Workflow:
wfDB = new WFDB(user, ident, "jdbc:oracle:thin:@", "host:1521:tnsstring");
String charset = System.getProperty("CHARSET");
if (charset == null) {
charset = "UTF8";
ctx = new WFContext(wfDB, charset);
if (ctx.getDB().getConnection() == null) {
throw new Exception ("Keine Verbindung zum Workflow");
On OC4J integrated in JDeveloper everything works fine when i run my test-servlet with this code.
On 9ias with OC4J running on a SuSE-Linux Server i get the following Error:
java.lang.SecurityException: class "oracle.apps.fnd.wf.WFContext"'s signer information does not match signer information of other classes in the same package

As you can see, the first Workflow-API-Object (WFDB) gets correctly instantiated. But the second one crashes.
The java.policy and java.security files are exactly identical on both machines, my PC and the Linux-Server.
Where might be the problem ?
How can we fix this ?
thanks in advance for any help
Ralf

okay, okay,
my/our own fault.
To prevent anyone else of makeing the same mistake, a short decription:
We stored the wf????.jar files inside the $JAVA_HOME/jre/lib/ext directory.
The correct way is to let them inside $ORACLE_HOME/jlib dir of the oracle db and extend the classpath, respectively add the following lines to 'orion-application.xml' of the app.
<library path="$ORACLE_HOME/jlib/wfapi.jar" />
<library path="$ORACLE_HOME/jlib/wfjava.jar" />

UCM Java API documentation

Hello,
SharedObjects.getEnvironment() method is deprecated, but didn't find any documentation on intradoc java api... So what method should be used instead? Does any body knows where to get intradoc java api documentation (even for Oracle ISV partners). There is no such documentation on Oracle portal, on partner portal, ...
Many thanks in advice.

From our development team:
In 10gR3, getEnvironment has been replaced by two different methods.
getSafeEnvironment: Gets the environment without variables that are considered unsafe to expose. For instance, it won't include JdbcPassword, IntradocDir, etc. A complete list is in the resource table SecureEnvironmentKeys in the file std_resources.htm. When evaluating Idoc script in an unsafe context (which is most of the time), the DataBinder should have a reference pointer to the safe environment and not the secure environment.
getSecureEnvironment: This includes all configuration parameters. It is used when doing admin level tasks of all sorts.
Also, the getEnvironment method still exists, but it is a pointer to getSafeEnvironment.

Has any java api can scraping Legacy System (Terminal such as tn3270)

Has anyone know java api or method that can scraping user interface of terminal emulator such as tn3270, 5250? I try to search a lot in google but still can' t find. i saw many products that were written in java. I think there is the way to develop it.
For now. only one method to scrap the terminal that i know is using winhllapi with C#.
someone guide me plz thank you very much

Hi,
PJCs will stay, same for Java Importer. You are right that we didn't publish any Javadocs until yet. I'll takle this one up to again suggest to the developers. Only the minority of classes though are Forms classes, the rest are UI classes with consume from an internal group.Just to be clear, PJCs, JavaBeans and Java in Forms will not phase out.
Note also that PJCs don't help you to migrate Forms to J2EE, they help you to use Java in Forms.

Inetgrating MDM Java API's with Java proxies on XI side

Hello friends
Can anyone help me on integrating MDM JAVA API's used for talking to MDM Server and the Javaproxies we generate from the XI side.I am having an application class inside the Java API's (it contains the main function)which triggers the functionality on the MDM side.But how to trigger it from the Java proxies side??I can get the different fields that I have to send in the impl.java program of my generated proxy,but how to trigger the MDM Java API's from inside this.Also there is one problem I needed to pass the datatype fields from the Javaproxy(XI)side to the CRUDMAINTABLERecord program..Since importing the javaproxy package is giving me an error(I don't know why)I don't know how to pass these datatypes to the CRUD program.Please help me out on this urgently.Thank you all in advance.

Hi Deepthi,
I had used the below code for retrieving the workflow's id's
RetrieveWorkflowsCommand RetriveworksFlows = new RetrieveWorkflowsCommand(connections);
RetriveworksFlows.setSession(session);
try{
RetriveworksFlows.execute();
catch(Exception e)
WorkflowProperties[] workflowpro = RetriveworksFlows.getWorkflows();
WorkflowId[] workflowid = new WorkflowId[workflowpro.length];
for(int n=0;n<workflowpro.length;n++)
workflowid[n] = workflowpro[n].getId();
String workfloName = workflowpro[n].getLaunchType()+"";
System.out.println("id--"workflowid"name"+workfloName);
and for creating the workflow job id i had written the below code
CreateWorkflowJobCommand workflowjobcommand = new CreateWorkflowJobCommand(connections);
workflowjobcommand.setWorkflowId(workflowid[0]);
workflowjobcommand.setRecordIds(recordId);
workflowjobcommand.setSession(session);
try{
workflowjobcommand.execute();
