Use Classes from another webapp

Hi Everybody!
I have a webapplication, lets call it "MyWebApp".
Furthermore I have installed axis in Tomcat.
Now what I want to do is, create a class, situated within the axis directory, that uses classes that are stored in the "MyWebApp" application.
Is this possible? If yes, how?
Thanks in Advance!

Using classes from another jar?

Hello,
Could anybody show me an example for how to put a shared library of classes in one jar file, and put an applet in another jar while the applet can use classes in the first jar file? Is this even possible at all???
Thanks!

norsez, did you had a look at the Java Tutorial:
Using the APPLET Tag
http://java.sun.com/docs/books/tutorial/applet/appletsonly/html.html
It says: 'You specify JAR files using the ARCHIVE attribute of the <APPLET> tag. You can specify multiple archive files by separating them with commas [...]'. I assume all listed JAR files are in the classpath then and you should have access to their classes.
Let us know if it works!

Importing a class from another context?

Hi JSP techies,
Im using RESIN and having a simple problem of figuring out how to import classes from another context, if Im using the right word.
ie.
My .jsp files are under $home/resin/doc/test dir. And in the jsp file, I would like to import a servlet class or a plain java class. But the servlet classes and all other classes are located under $home/resin/webapps/project/WEB-INF/classes/a/b/c
Hence when I say
<% page import="a.b.c.*" %>
I get an error saying "a" not found.
1. When I say "servlet classes are in a different CONTEXT", is that right? or is it just another directory?
2. How can I make the jsp file import the classes from the servlets class path?
Note: Ofcourse, when I copy the package to the
$home/resin/doc/WEB-INF/classes dir, everything works fine. But thats simply not an efficient way to get around. Could anyone clear my doubts on this regd.?
Thanks in advance.

Oh... I get it now. I'm sorry, I had you poorly misunderstood. You are trying to import servlets from another web app or servlet context. I would suggest you put servlets that are common to all web apps in the system classpath and not tie them to any particular web app. In other words create a package directory structure from the system's root directory or any where outside of any web apps and point the system classpath to the beginning of that directory structure. I have a similar thing going with Tomcat. I have a folder in my root called Java_Class which is in my classpath. I build all common utilities in this directory. So I have a com/craig/web structure that holds my AppServlet which is in package com.craig.web. This servlet is visible to all web apps via the Windows classpath. Servlets particular to an application like say an MusicOrderProcess servlet would reside in a package under the webserverhome/webapps/MusicStore/WEB-INF/classes directory where webserver home is the home directory of the webserver you are using. I've tested this across webservers as well (orionserver and Tomcat) and it works.
From the prompt you include in your posts I am guessing that you are running on UNIX. Move your common servlets out of their respective web apps and into a common directory structure. Configure the UNIX $CLASSPATH (or is it $classpath?) environment variable to point to this sturcture and you'll be on your way!
Post again if you have more questions!

This is what my exact problem.
i've created a bean (DataBean) to access the database. i'm having a servlet program (ShopBook). now to check some details over there in the database from the servlet i'm in need to use a method in the DataBean.
both ShopBook.java and DataBean.java lies in the package shoppack.
in ShopBook i tried to instantiate the object to DataBean as
DataBean db = new DataBean();
it shows the compiler error, unable to resolve symbol DataBean.
note:
first i compiled DataBean.java, it got compiled perfectly and the class file resides inside the shoppack.
when i'm trying to compile the ShopBook its telling this error.
hope i'm clear in explaining my problem. can u please help me?
thank u in advance.

Accessing a variable defined in one class from another class..

Greetings,
I've only been programming in as3 for a couple months, and so far I've written several compositional classes that take MovieClips as inputs to handle behaviors and interactions in a simple game I'm creating. One problem I keep coming upon is that I'd love to access the custom variables I define within one class from another class. In the game I'm creating, Main.as is my document class, from which I invoke a class called 'Level1.as' which invokes all the other classes I've written.
Below I've pasted my class 'DieLikeThePhishes'. For example, I would love to know the syntax for accessing the boolean variable 'phish1BeenHit' (line 31) from another class. I've tried the dot syntax you would use to access a MovieClip inside another MovieClip and it doesn't seem to be working for me. Any ideas would be appreciated. Thanks,
- Jeremy

I would approach it in much the same way as you would in java, by making getters and setters for all of your class variables.
Getters being for returning the values, Setters being for setting them.
So you would make a get function for the variable you want to access ala:
function get1PhishBeenHit():boolean {
return this.phish1BeenHit;
Then to access the value of that variable from outwith the class:
var result:boolean = ClassInstanceName.get1PhishBeenHit();

So i have to kill that JInternalFrame.Yoinks.
To be begin with your problem sounds like you are doing everything in one thread. So stop doing that. Second when you get it split up and if a task is taking too much time then interrupt it. No kill. Interrupt. This means the worker thread needs to check sometimes if it has been interrupted.

How to call a Java class from another java class ??

Hi ..... can somebody plz tell me
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()

Can we use Result from another query in Webi using Bex uery universe?

Hi,
Can we use Result from another query filter option in Webi to create a report using a Bex Query universe?
I need to create a report using two universes, one is Bex Query Universe and the other is Orcle universe. I have two queries, one is using Oracle universe; the other using Bex Query universe. I need to pass the Oracle data from the Oracle query to the Bex Query query to get the matched data from SAP Bex query.
I used Result from another query in the query filter panel for the query using Bex query universe. But I got an error saying that 'A filter contains a wrong value. you cannot run this query. (Error: WIS 00007). The data used in the filter on both sides are the same. they are char.
I have tested by using two queries from the same Bex query universe to see if the Result from another query filter option works. And I got the same error.
Has anyone run into the same issue and if this is possible and what should be the solution?
Thanks in advance!
Edited by: BO_Haiyan on Oct 6, 2010 3:47 PM

In that situation:
Create two queries : Oracle and BW query.
@ Report:
As you have to see result set from both the Dataproviders, correct? To achieve thise one must have common dimension objects to merge them at report and use Objects those are coming from both queries to use them in single Table/Report.
Unless you don't use Merge Dimensions, you don't get a chane to use both queries objects in single Table/Report. (It will give tooltip saying: You can't drop here -- Incompatable Objects)
In case, if you don't have common dimensions, change object definitions to Detail objects, for those required.
Hope it helps you.
Thank You!!

Using data from another View

Is it possible to create a new Grid in the same analysis where calculated/Grand Totals columns/rows may be used?
I understand there is a feature use results from another analysis but wonder if it can be used in the same. Thanks.
Adi

Hi,
Say you have a report for retrieving Sales by Products for a company and showing up grand total of sales for all products too in the same report. So, how about a case where you would like to see each product's contribution to the whole sales numbers? For this, a new column could be something like
Measures.Sales*1.0/SUM(Measures.Sales)
Here Measures.Sales is the sales for each product and SUM(Measures.Sales) is nothing but the total sales ie grand total.
Hope this helps.
Thank you,

ANT: Include classes from another jar

Hi all.
Can I add classes from another jar to be added into my jar-file?
Other words, may I write something like this:
<target name="jar" depends="compile">

basedir="${compile.dir}"
includes="another.jar" >
</jar>
</target>
in my build.xml?
Thanx a lot for Your tips.
Regards, Volodymyr Shram.

I've found some resolve:
<target name="jar" depends="compile">
<unjar src="another.jar" dest="another_dir"/>
<jar jarfile="deploy/my.jar">
<fileset dir="${compile.outdir}" includes="**" />
<fileset dir="another_dir" includes="**" />

But is it only way? Can I add classes from another.jar to my.jar without extracting?

How Do I Run A Class From Another Class?

Hiya everyone, id like to know how to run a class from another class.
Ive got a Login class which extends a JFrame and a Personnel class which also extends a JFrame. When i press the login button (in Login class), ive got it to decide if password/login are acceptable and if they are, I want the Login class to close then run the Personnel class.
Im just after the code which says to close this class and run the Personnel class. How do i do that?
Ive researched this but couldnt get an understandable answer!
Help would be much appreciated, Ant...

This is the Login Class:
public class MainMenu extends javax.swing.JFrame {

How to refresh a JTable of a class from another thread class?

there is an application, in server side ,there are four classes, one is a class called face class that create an JInternalFrame and on it screen a JTable, another is a class the a thread ,which accept socket from client, when it accept the client socket, it deal the data and insert into db,then notify the face class to refresh the JTable,but in the thread class I used JTable's revalidate() and updateUI() method, the JTable does not refresh ,how should i do, pls give me help ,thank you very much
1,first file is a class that create a JInternalFrame,and on it there is a table
public class OutFace{
public JInternalFrame createOutFace(){
JInternalFrame jf = new JInternalFram();
TableModel tm = new MyTableModel();
JTable jt = new JTable(tm);
JScrollPane jsp = new JScrollPane();
jsp.add(jt);
jf.getContentPane().add(jsp);
return jf;
2,the second file is the main face ,there is a button,when press the button,screen the JInternalFrame. there is also a thread is beggining started .
public class MainFace extends JFrame implements ActionListener,Runnable{
JButton jb = new JButton("create JInternalFrame");
jb.addActionListener(this);
JFrame fram = new JFrame();
public void performance(ActionEvent e){
JInternalFrame jif = new OutFace().createOutFace(); frame.getContentPane().add(JInternalFrame,BorderLayout.CENTER);
public static void main(String[] args){
frame.getContentPane().add(jb,BorderLayout.NORTH);
frame.pack();
frame.setVisible(true);
ServerSokct ss = new ServerSocket(10000);
Socket skt = ss.accept()'
new ServerThread(skt).start();
3.the third file is a thread class, there is a serversoket ,and accept the client side data,and want to refresh the JTable of the JInternalFrame
public class ServerThread extends Thread{
private skt;
public ServerThread(Sokcet skt){
this.skt = skt;
public void run(){
OutputObjectStream oos = null;
InputObjectStream ios = null;
try{
Boolean flag = flag;
//here i want to refresh the JTable,how to write??
catch(){}
4.second is the TableModel

Using methods from another Form C#

Hello!
I'm having some trouble using methods from one Form in another one. Here's the deal:
This is a snippet from my 'main' form:
public partial class PRINCIPAL : Form
//some variables here
Form2 Config = new Form2();
Form3 Cadastro = new Form3();
public PRINCIPAL()
InitializeComponent();
//code goes on and on
//Here's the method I want to call on the other forms (Form2 and Form3)
public void salva_banco()
this.Validate();
this.projetoBindingSource.EndEdit();
this.modulosBindingSource.EndEdit();
this.funcaoBindingSource.EndEdit();
this.estadosBindingSource.EndEdit();
this.tableAdapterManager.UpdateAll(this.database1DataSet);
//And here is where I show Form3
private void projetoDataGridView_CellDoubleClick_1(object sender, DataGridViewCellEventArgs e)
Cadastro.ShowDialog();
//And here is where I show Form2
private void funcaoDataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
Config.ShowDialog();
}// And the code keeps on going}
And this is a snippet from Form3:
public partial class Form3 : Form
public Form3()
InitializeComponent();
private void Form3_Load(object sender, EventArgs e)
this.projetoTableAdapter.Fill(this.database1DataSet.Projeto);
this.modulosTableAdapter.Fill(this.database1DataSet.Modulos);
private void btnOK_Click(object sender, EventArgs e)
if (projetoTextBox.Text == "")
MessageBox.Show("some text here");
else
////// HERE IS THE PLACE WHERE I WANT TO CALL THE METHOD! "salva_banco()"
I've read lots of suggestions but none satisfied my condition.
I appreciate any help.
Thanks.

You need to find the instance of the PRINCIPAL form to call the method on. If you know there will always be exactly one open you can use:
var principalForm = Application.OpenForms.OfType<PRINCIPAL>().Single();
principalForm.salva_banco();

Instantiating a class from another package

Hi,
I have two packages, say "framework" and "impl" -
framework package (framework.jar)
- contains base classes
- contains factories to instantiate concrete classes
- bundled in <product>.ear
impl package (impl.jar)
- contains implementation(concrete) classes
- compile time dependency on framework.jar
- bundled in <product>.ear
I could successfully compiled and build <product>.ear which contains both the jars. The ear gets deployed successfully.
PROBLEM
Now, whenever a factory class (part of framework package) tries to instantitate an impl class (part of impl package) using -
Class.forName(impl.ConcreteClassName OR fully_qualified_concrete_class_name).newInstance();
It throws "classNotFoundException". It is not able to locate the concrete class.
So, my question is how can i instantiate a class using its fully qualified name(package.classname) from another package ?
Thanks.

Now, whenever a factory class (part of framework package) tries to instantitate an impl class (part of impl package) using -
Class.forName(impl.ConcreteClassName OR fully_qualified_concrete_class_name).newInstance();
It throws "classNotFoundException". It is not able to locate the concrete class.This sound like a classpath problem. Check your ear's manifest.
BTW:
Shouldn't the framework better use ServiceRegistry to load implementations?

Use Classes from another webapp
