Calling java files

I have two java gui files in different packages. I want to call one file by clicking the button of the other file. can anyone tell me how to do it?

How to call java files from different directories

hi, how do i call java files from a different directory??
let say i got partA.java, and i need to include functions from partB.java which is in a different folder. how can i do that?

Chicon wrote:
Hi nuttynibbles,
Before the class declaration in partA.java, you must have an import statement like :
import someDirectory.partB;
public class partA {
... and before you ask... you'll probably want to read through this http://java.sun.com/docs/books/tutorial/java/package/index.html

How to call java file when entering the another jsp page.

when i click the link to link to another page, when enter the page, how can i call java file and passing id parameter to call method, which is connected to DB.
when enter the page, how can i call java file together with one arguement???

I would strongly suggest to go the MVC way. Please perform all DB operations through a Servlet/Action instead of directly hitting the JSP and then invoking a java bean to do the DB operation. JSP should only do the rendering.

Getting Error while Calling Java File from oblixpppcatalog.lst file

Hi,
We are trying to configure userservcenter_workflowCreateProfile in oblixpppcatalog.lst file to call a java class that returns an xml file as below
<?xml version="1.0" encoding="UTF-8"?>
<ObEventParams
xmlns="http://www.oblix.com/">
<ObParamList name="ObRequest">
<ObParam name="sn">
<ObValue>Smith</ObValue>
</ObParam>
</ObParamList>
</ObEventParams>
But when we try to run this code by clicking on "Create User Identity" we are getting "An error in Pre/Post Processing of the Page has Occured" or Some times we get "Parse error in XML document sent by event handler to identity server".
Can some please shed some light on this issue?
Thanks,
Ganesh

Hi Ganesh,
That event xml looks rather incomplete - I would expect it to contain information about the workflow, and workflow step etc. For example, I have a Create User workflow that generates Event XML beginning:
<?xml version="1.0" encoding="utf-8"?>
<ObEventParams
xmlns="http://www.oblix.com/">
<ObParamList
name="WfInstance">
<ObParam
name="obwfinstanceid">
<ObValue>f92cab82ee4b43ccba42869bb2928d0c</ObValue>
</ObParam>
<ObParam
name="obworkflowdn">
<ObValue>obworkflowid=060efe6966674e54be63383290d81e63,obcontainerId=workflowDefinitions,o=Oblix,dc=example,dc=com</ObValue>
</ObParam>
<ObParam
name="obworkflowname">
<ObValue>Create User</ObValue>
etc etc...
You could look at the Event XML that is sent to the plugin from your workflow to a file by reading STDIN and dumping it to a file. There is an example of this in Note 843570.1 (happens to be for a password change event, but it should work for any ppp exec event). Then your code could change the Event XML as required, but keeping the basic structure of the data that is sent to it.

Calling a method from another Java file.

I think I'm doing this right, but I'm obviously going wrong somewhere.
In order to not have one big long java file, I've created one main one to execute the program, and another to do some of the functions. I'm using eclipse, btw.
In the main file, I have
currentTB = getActiveTB(playerArea);If it works, it should get send the player area variable to the getActiveTB method, and store the value it returns in the currentTB variable, right?
In the other file, I have;
package scenes;
public class sceneIndex {
     private TerrainBlock getActiveTB(String areaCode) {
          TerrainBlock tBlock = new TerrainBlock();
                 **DOES STUFF**
          return tBlock;
}I have it set up so the second file is in the source folder "resources" and the package "scenes." The problem is I'm not calling it properly. I'm missing something simple, I think. The only error I'm getting is;
The method getActiveTB(String) is undefined...
Where am I screwing up?
EDIT: Yeah, I'm a rookie here trying to figure it out on my own. My computer science courses, so far, conveniently all consist of just one big java file. Easier to write, sure, but not very efficient/organized.

Yeah, so this is still pissing me off. I'm not sure what else to do. I've tried this a million different ways, in both eclipse and netbeans. Whatever.

Calling a created Java file from an AIR application

I've got a guy helping me out who is creating a Java file that outputs an F1 keypress to the operating system/desktop (which Flex alone can't do.
My problem is I need to know how I can call/activate this file from within an AIR application. I want my app to be ready for when he has created it for me but I've never used Flex to call an application so I would not know what classes need to be called or if any script would be required.
In the following simple code lets say if the Java file itself was called keypress.java (or whatever file extension a java file has) what code would need to be added in, including imported classes, to make the click of the button activate this java file?
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Button id="KeypressButton" label="Button" horizontalCenter="0" verticalCenter="0" click=""/>
</mx:WindowedApplication>

I think one solution is to use a Java proxy to call the Web services.
In the Java proxy you can have a method that accepts the user/pass and sets them correctly for the Web service.
Then you expose that Java proxy as a data control (right click, create data control) - and then create a page that invokes that method.
(For the basics of working with a POJO data control see: http://blogs.oracle.com/shay/2009/07/java_class_data_control_and_ad.html )

How to call java class file from jsp

hi
we need to call java classes (which are written separately in .java file )from jsp file. we need it for our project if anyone knows about please reply us.
bye
siva sankari

you can call the methods in a lot of ways. you could use scriptlets with the
<%@ page import="package.class"%> and then inside instantiate an object
<%
MyClass mc = new MyClass(parameters if any);
mc.theMethodYouWantToCall();
%>or as Madathil has stated,
or use the JSP tags
<jsp:useBean id="anyname" class="classname"/>and then use the getProperty tag
or even Custom Tags

How to call a html file in a java file

how to call a html file inside a java file ?

Hopeless. Are you by any chance a rare gas? You seem completely inert. LOL You totally pwned him there :rolls eyes:
well, no, I think he's looking for something to this degree:
in HTML, there is a mailto: command that makes the system default handled way to email emails open up. He's looking for a command thats very nice and opens a html file in the system default browser.
So, Dick, Runtime.exec would work execpt that he needs a way to find the default system browser to call exec on, AND he has to know how to pass html file locations to the executable via command line arguments
He just didnt try to phrase it at all :P

Call a Java file from ABAP

Hi,
I would like your help in identifying a mechanism in calling a Java Program from an ABAP program. The requirement is that I need to pass enough parameters(possibly in a single object like a table) and fetch that in a Java Program residing in a jar in the J2EE engine. The possibility of this java file interpreting this incoming object and also be able to return something to ABAP which can eventually be printed on the screen needs to be known.
I also would like to validate an assumption of mine which is that, the jar(the receipient java file) file needs to be put under the directory
"\usr\sap\SystemID\instancenumberj2ee\deploying\lib"
Appreciate your time and effort in helping me with this.
Regards,
Sam.

i am not sure about
I also would like to validate an assumption of mine which is that, the jar(the receipient java file) file needs to be put under the directory
"\usr\sap\SystemID\instancenumberj2ee\deploying\lib"
but for your case what you could do is, on the java side get developed a jsp page which will receive data and use the jar to proces and return the results as xml. once thats done.
from abap you can use cl_http_client class to call this jsp page to pass parameters and get the processed results from jsp page.

I had a generic record class that has a HashMap to hold the data fields (...)
method called createRecord() for each record type which would populate the HashMap with the correct data fieldsI'm not sure I understand: are the contents of this field map the same between two records of the same type? Then yes, you don't need to clone the map per record instance.
one thing that needs fixing is the fact that each time the createRecord() method is called I'm creating a new fieldMap to define the dataFields in the record class.Probably, but that will only get you a little bigger files; you won't gain an order of magnitude on the size of files. The problem for huge files is that as soon as their content is bigger than the available memory, you'll run into problems. A more radical approach if you need to address huge files is to process the records on the fly, and not load all records in memory. Of course not all algorithms or business logic can afford that...
I know I could rewrite the code and create a class for each record type and declare the fieldMap static but I was wondering if anyone had any better suggestions The Record instance could receive and keep a reference to its RecordType instance, and ask the RecordType instance the DataType for a field's name. That way the RecordType encapsulates the map, and there's less risk that a clumsy other class modifies the static map.
before I go rewriting a load of code.A load of code?!? Even with the idea of the static map, you only have to edit the enum type (well more accurately, each RecordType enumerated constant's createRecord() method).

Simple Question Calling methods from Java files through JSP without JVM

Hi.
I've got a simple question (forigve my newbieness)...
If I'm running Tomcat can I exectue a method in a compiled Java file from a JSP page without having the JVM installed on the server?
Any thoughts or additional comments would be appreciated.
Many thanks.

No... but that's because you can't run Tomcat without
a JVM installed on the server.
If you are running Tomcat, you are running a JVM for
the JSP pages to run in, in which case, yes, the JSP
pages can call the other Java code... as long as it's
in the classpath.Thanks a lot for the replies.
So just to check, if I sign up with a hosting company that offers Tomcat then the JVM will be installed on the server and I can call other Java code as long as it's in the classpath?
I just want to make sure before I sign up with a hosting company =D
Thanks again!
