Call Windows COM/DCOM objects from Java on Linux

Hello, is it possible to call COM/DCOM objects running on Windows from Java on Linux machine? Thank you.

I don't know anything about it but it looks like EZ JCom in conjunction with the included Remote Access Service does what you're after. It's not free though.

Calling Window's Dll Functions from Java

Hello Audience,
Is there a way to call Win32/64 based Dynamic-Link-Library functions from Java?
Thanks,
GenKabuki

Yes.
In general, if you are trying to call functions in an existing dll, you will have to write a "wrapper" dll that meets the java jni interface requires. There are tools around wich purport to generate these for you. Do a google serach; among other tools, you should turn up JACE.

Hi,
case 1: for WDP, you can create the web service model via "Import Adaptive Web Service" or "Import Web Service Model (deprecated)" by supplying wsdl URL.

case 2: In ABAP, create a proxy object at trx code SE80.

Both cases are wizard-based. It's pretty intuitive.

Fall into a trouble when calling a dll from java in linux

Hi, experts:
I encountered a big trouble when using JNI to call a C++-compiled DLL from java in Linux: The DLL function didn't execute immediately after the invocation, and was deferred till the end of the Java execution. But all worked well after migrating to windows. This problem made me nearly crazy. Can somebody help me? Thanks in advance.
Linux: fedora core 8, jdk1.6.0_10,
compile options: g++ -fPIC -Wall -c
g++ -shared

It looks like the OP compiled the C source file and linked it into a Windows .dll, which would explain why it worked flawlessly in Windows. (Though I must say the usage of GCC would make someone think it was compiled in Linux for Linux, GCC also exists for Windows, so I'm not sure it's a Windows .dll either...)
@OP: Hello and welcome to the Sun Java forums! This situation requires you to make both a .dll and a .so, for Windows and Linux. You can then refer to the correct library for the operating system using System.loadLibrary("myLibrary"); without any extension.

Calling inactive version of ABAP object from Java

Hello,
When I call an ABAP object from Java Program which version of ABAP object is called inactive or active ?
Is there a mechanism to call the current inactive version or any other previous inactive /active versions ?
Regards,
Tarun

Only the "active" version of ABAP code is active and runnable.
You cannot run inactive versions. Like you have to compile a .java file to a .class file o make it runnable in the JVM.

Calling Windows XP FTP Command in java

Hi there!
Need help in calling Windows XP FTP command in java:
executing the FTP command in DOS works well, but when I tried calling it in java using Process and Runtime objects, it successfully transferred the files from remote to my local pc... but I seemed to be stuck with .exec() and cannot continue with the other statements.
I know that I can use eFTPj or Apache Commons Net .. but I have no more time to study it since I have no more time left.
Any idea or suggestion? I badly need your help�
Take care and God bless,
MaDz

Solution:
Better use Apache Commons Net - FTP for greater java support.

Calling JSON based RESTful endpoint from Java

I have a scenario where I need to call a RESTful web service based on JSON response object from Java.
And then make a web service for this Java program that I have made.
Can any one please help me with this?
Thanks

If you would have typed 'Java RESTful' in Google the answer would have come to you in about 2 seconds.
Read up about using the JAX-RS API.

Returning objects from Java stored procedures

I need to pass an object from Java to a Java SP which updates the object and returns the object back. The Java SP will be calling a PL/SQL procedure which returns some nested tables that I want to stick into the passed object.
I tried using "IN OUT" for the object in the call spec but got an error that it was not "appropriate for the parameter". So, the next option seems to be to pass it in and then return it from the Java SP. I'm just wondering though what the the best approach for accomplishing this? I've looked through some of the sample code on the OTN but haven't found anything yet that really helps.

I am trying to use custom object classes. I have setup a type map for the connection and my custom class implements SQLData. Yet, when my client tries to call the Java SP, it gets ORA-00932 complaining of inconsistent data types (expected IN conversion failed).
I turned on some debug info (i.e. oracle.jdbc.sql=true) but it didn't provide any useful info in regards to why I'm getting this error. Unfortunately, the JDBC Developer's Guide does not provide full examples of the code.

Calling a PL/SQL function from java

I would like to call a pl/sql function from java. My pl/sql function is taking arrays of records as parameters. How do i proceed? Which specific oracle packages do I have to import?
Please send an example.
TIA,
Darko Guberina

Documentation here: http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref185
says JPublisher can publish records too.
But when I change the example given at http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref190 as following:
PACKAGE "COMPANY" AS
type emp_rec is record (empno number, ename varchar2(10));
type emp_list is varray(5) of emp_rec;
type factory is record (
name varchar(10),
emps emp_list
function get_factory(p_name varchar) return factory;
END;
then I see <unknown type or type not found> at sql or java files generated. Any ideas?

How to create windows users and groups from Java

Hi,
Can any one please tell me, which Package/API will helps to create windows users and groups from Java.
Thanks,
M.Prem.

You can't do it with pure Java, and it's not in the core API. You'd have to write a native function to do it, using whatever API Windows provides, and then call it with JNI. Or look for a third party native-based Java library that already does that.

Nwdi-managed access of pcd-objects from java web dynpro

Hi,
im am trying to access portal pcd-objects from a java web dynpro component (namely getting and setting personalized iview properties). for locally managed web dynpro components this works fine with the code below.
when i try the same with a nwdi managed web dynpro component i run into problems regarding references to used dcs. for instance, i need to reference used dc SAP_JTECHS/tc/epbc/pcm/adminapi/java because the build needs tcepbcpcmadminapijava.jar which is inside the mentioned dc. but access permissions of this dc don't allow the dependency. when i try to "add used dc ..." in nwds i get the error message: illegal dependency: access list does not allow use of ...
has someone any solution for this problem? are there other ways of accessing pcd-objects from java web dynpro (nwdi managed!)?
thanks

Hi Kust,
To access the PCD objects the code you used looks ok for me but your main issues is related to the dc access permissions. This thread discussed about the similar issue. Please review this below thread.

Cannot Acccess Applet Object from Java Script

Hi,
I am using jRE1.5, and Kava Chart Applets. Those applet jars are compiled in jdk 1.5 version. I have created one jsp where I used ,<applet> tag. The problem is when ever I am going to access the applet object from java script it is not returning the actual java applet object, when put an alert message it shows [object]. So i am not able to access the methods or the applet class.and also the screen gets hung, nothing is coming.It get stuck at the point where i tried to access the applet method like document.getElementById(applet_id).<<<some method of the applet class>>.Also it is not showing any kind of javascript error or Applet class exceptions.
But the strange thing is, when i use jdk 1.6, the page is running fine.Also when i try to print the applet object from javascript it is showing the proper class name.
Please help me solving the problem.

A number of changes and improvements were made between 1.5 and 1.6 - the entire plugin is new. You need to change to 1.6, as 1.5 goes EOL about November this year and future changes to this area in 1.5 are unlikely.

How register COM object from java?

Hi!
In my user home directory I have myCOM.dll. My sign applet use this myCOM.dll. But before use this dll I must register it (by use regsvr32).When myCOM.dll will be success register my applet can work. The problem is that I can not get answer from regsvr3 (is myCOM.dll are successed registered or not, or is user has a grants to register COM object and so on.)
Again, my java applet can work ONLY when myCOM.dll is registered.
How I can register myCOM.dll from java applet and if registered is not success exit from java applet?

I must not have been clear. I am not asking how to access a COM object using Java, we already have tools to do that.
The question is whether there is a way to define a COM interface using Java. I want to code my COM object in Java. Right now we are using PowerBuilder to code COM objects. I would rather use Java.

Issues in mapping objects from java to flex - using flex4

Hi,
I have a class in java which i want to send to flex4 using BlazeDS as middleware. There are a few issues that i am facing and they are:
When sending the object across (java to flex), the properties with boolean data type having value as true gets converted to properties with value as false. Even after setting the value to true it still comes as false on flex side. Can't understand why this is happening.
When sending the list of object containing property with boolean data type, the object on flex side does not show those properties at all. As of there were no boolean properties in that object.
Last but not the least, When sending List<ContractFilterVO> contractFilterVOs to flex using remote call, the result typecasted to ArrayCollection does not show the holding objects as ContractFilterVOs but as plain default Object though having all the properties send, except the boolean one mentioned in above points. Basically it is not able to typecast the objects in arraycoolection but the same objects gets typecasted when sent individually.
In all the above points i am using Remote Service through BlazeDS for connectivity with Java. I have done a lot of this stuff in Flex 3 but doing it for the first time in flex 4, is there anything that Flex 4 needs specific. Below is the pasted code for reference purpose.
Flex Object
package com.vo
     [RemoteClass(alias="com.vo.ContractFilterVO")]
public class ContractFilterVO{
     public function ContractFilterVO(){
     public var contractCode:String;
     public var contractDescription:String;
     public var isIndexation:Boolean;
     public var isAdditional:Boolean;
* Rmote Part of code
var remoteObject:RemoteObject = new RemoteObject();
remoteObject.destination="testService";
remoteObject.addEventListener(ResultEvent.Result,handleResult);
public function handleResult(event:ResultEvent):void{
     var contarctFilterVOs:ArrayCollection = event.result as ArrayCollection; //Point 2&3 probelem, if list sent form java
     var contarctFilterVO:ContractFilterVO= event.result as ContractFilterVO; //Point 1 probelem, if only single Object of type ContractFilterVO sent form java
Java Object
package com.vo
public class ContractFilterVO implements Serializable
     public function ContractFilterVO(){
     private static final long serialVersionUID = 8067201720546217193L;
     private String contractCode;
     private String contractDescription;
     private Boolean isIndexation;
     private Boolean isAdditional;
I don't understand what is wron in my code on either side, it looks syntactically right. It would be great anyone could help me point out my mistake here. Waiting for right solutions...
Thanks and Regards,
Jigar

Hi Jeffery,
Thanks for your reply, it did solve my query @ point 3 as well as point 2 where the objects in arraycollection were not geting converted and boolean properties did not appear when list of an objects were received. And hey, i did have public functions for properties defined java class, just forgot to mention here in post, sorry for that.
The solution you gave was right, but than what if i have a VO which has multiple List of objects coming from Java, than i would have to create an instance of each type of object on flex side this is too tedious, is'nt it? Is there any better solution... out there.
And jeffery do you some tricks up your sleeve for this Boolean issues to that i am facing in point 1... Still struggling with this one...
Anyone out there would be more than welcome to point my mistake, if any and provide tips/tricks or solutions...
Thanks again to Jeffery...
Waiting for more solutions sooner...
thanks and Regards,
Jigar
