How to call a Java Class from another Java Class assuming both in the same Package??
I want to call the entire Java Class (not any specific method only........I want all the functionalities of that class)
Please provide me some slotuions!!
Waiting for some fast replies!!
Regards
Smita Mohanty

Hi Smita,
you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
e.g.
you have developed A.java and B.java, both are in same package.
in implementaion of B.java
class B
            A obj = new A();
             //to access A's methods
             A.method();
            // to access A's variable
            //either
           A.variable= value.
           //or
           A.setvariable() or A.getvariable()

Is it possible to call one mathscript function from another?

HI iam bahrath..i need call the operation takin place in one mathscript in another..is it possible?pls help..

Thanks for your concern..let me explain my project.Iam actually developing a system which provides the stress strain relationship of a material..For calculating strain which is nonlinear in this case we are using image processing techniques.We take a picture of the system initially with light markers and we find the centroid of all the markers(i use four of them).After the force is applied on the particle the centroid of the markers change as the marker positions change.I use this change in the centroid and calculate the strain.Now, 90% of the code is ready in matlab(jus capturing image and usin is needed).But i have been asked to implement it in labview.so iam tryin to put the code in mathscript and try.But the problem i face is incompatibility of many functions like imshow,input etc.so im implementin parts of the code inlabview mwthod and rest in mathscript.In matlab code i have two files and call the function in in another file from one file..thus i thought i might use two mathscripts and call one from the other..pls help.

How I can call controller's functions from another component?

Hi again!
I make a few web Dynpro components, for example first for user-data processing, second - for project-data processing. In the controller of 1-st controller there is a function getUserById(). In the controller of 2-nd component I need such function. And I don't want to make a dublicate for this function in the controller of 2-nd component. Is there a way to call function in one component from another?

Hi,
     Yes, you can reuse the component. There are two basic types of component communication. 1. Intra Component communication 2.Inter Component communication.
1. Intra Component communication: The two components must be in same DC(project).
Procedure:Say there are C1,C2 components in a DC.
Open C2, Open interface controller, create a similar (_parameters and return type_) method to the method C2. Call C2's method in this Interface method.
Open C1, select and right click Used Web Dynpro Components -> Add Used Component. In the wizard, you can browse and select the C2 component,and enter a name to the usage. Then the usage of the interface <b>must </b>be added in properties required controllers of a view/component controller.
Now we can use the method that is available in the C1 interface controller.
You must define method before declaring usage
<b>2.Inter Component communication:</b> The two components are in different DCs
Open DC metadata of C2. Right click on Public part-> create new Public Part.Enter name-> Next -> Select entity type as Web Dynpro Component in wizard,in Select Entities select the component ,Finish.
A structure for public part is created.
Open C1, Open DC metadata of C1. Right click on Used Dcs-> AddUsed DC. Browse to C2's public part.
Select Finish.
regards,
Siva

How to get properties of a bean from another java class

Hi,
I am new to JSF. Currently I am facing a problem, and hope you experts can give me some guidance.
The JSF app i am working on has one Java class for handling a tree structure, MyTreeNode.java, and it also has a bean, NameBean.java, which has two properties, username and password.
I can easily associate an input text with the #{name.username} to store the user's login... but later on, I need to fetch that information inside of MyTreeNode.java. How do I do that? Thanks!

Referencing WMI Manageable class from another WMI Class

Hi,
I am trying to have WMI manageable class referring to another WMI manageable class
Something like
[ManagementEntity]
Class A
[ManagementEntity]
Class B
        [ManagementReference(Type = "A")]
        [ManagementProbe]
        public A AClass;

Hi,
The Microsoft ManagementReference sample you mentioned contains a bug:
Instead of:
inst.LetterNumber = "Letter = " + i;
inst.PhoneticNumber = "Phonetic = " + i;
The exact text (where spaces in the string are important and must be removed) should be:
inst.LetterNumber = "NumberLetter.Number=" + i;
inst.PhoneticNumber = "NumberPhonetic.Number=" + i;
With this fix, the hierarchy can now be navigated properly.
c.f. my response to the following blog post:
http://juggledthoughts.blogspot.co.uk/2008/06/wmi-association-classes.html
I have also
logged a bug on MSDN Feedback so please vote on this if you'd like them to fix the sample.

Calling one java program from another

Hello,
How can I start another java program from one? Lets
say I want Second.java to start by calling it from
First.java. How do I do it? The two programs are given
below. Any help is appreciated.
Thanks,
Amanda
First.java
import java.io.*;
import java.lang.reflect.*;
public class First
     public static void main(String[] args)
          Process theProcess=null;
          System.out.println("Hello World from First.java!");
          String second=new String("Second.java");
          //System.load(second);
          //Runtime.getRuntime().load(second);
          try
               theProcess=Runtime.getRuntime().exec( "Second.java"
               System.out.println("after exec");
          catch (IOException ioe)
               System.out.println(">>IOException thrown in
First.java while calling
Second.java."+ioe.getMessage());
Second.java
public class Second
     public static void main(String[] args)
          System.out.println("Hello World from Second.java!");
}

Thanks, warnerja
What if Second.java is on a remote machine i.e.
First.java and second.java are on different machines?
Will I have to use RMI?Well, you'd have to do some kind of remote invocation. Depends on what kinds of apps house the classes. There are all kinds of ways - web services, servlets, RMI, (maybe others...)
That's a totally different question than what you originally posted, and would have been very relevant to say so in the first place.

Calling one WTC service from another WTC service

Hi,
We have a service called COLLECT defined in our WTC server.
Recently we've added a second service called SUM in the same WTC server.
We were wondering if it's possible to call SUM from COLLECT, and if it is, what configuration changes should be made in order to do it?
Currently both services are exported by the WTC server (and imported by our Tuxedo).
Thanks,
Shy

Hi Shy,
Although I haven't tried it, I'm fairly certain you cannot call a Tuxedo EJB using tpcall() within a WTC based application. What I normally advise customers to do when writing a Tuxedo EJB is to implement two separate interfaces. One is obviously the TuxedoService interface that all Tuxedo EJBs must implement. In particular you must implement the service() method that accepts a TPServiceInformation instance that provides access to the typed buffer passed to the EJB. Normally one then extracts the necessary fields or information from the typed buffer, performs whatever necessary business logic needs to be performed, and then constructs a reply typed buffer.
What I recommend is that you separate out the business logic into a separate interface and have your class implement both interfaces. The service() method would only deal with the marshalling/unmarshalling of the information contained in the typed buffers, and leave all business processing to methods on the second interface. Then if you need to access another "service", you would use the second interface, thus saving you from all the typed buffer manipulation.
So in your case, the business logic in the second interface of the COLLECT implementation would simply call the SUM implementations second interface (the EJB's business logic) instead of trying to call a Tuxedo service. While this helps in reuse of the business logic, it doesn't address the issue of trying to transparently move a service implementation from say Tuxedo to WLS. If that's what you are trying to do, you might try exporting the SUM service from WTC to the Tuxedo domain gateway, and then importing the SUM service from that gateway. This would likely cause a network round trip if it works, but it's something to consider.
Another alternative is to use something like the Apache Tuscany/Java project and build your Java applications using SCA. Tuxedo SALT includes a Tuscany/Java binding extension that allows Tuscany/Java applications to transparently call Tuxedo services. The choice of whether to actually call a Tuxedo service or call a Tuscany/Java based SCA service is determine by the binding selection and not changes in your code. Just a thought...
