How to call a function in one .js file from another .js file

Hello Techies,
I am trying to call a function in two.js file from one.js file.
Here is my code
one.js
<script>
document.write("<script type='text/javascript' src='/htmls/js/two.js'> <\/script>");
     function one()
                    var a;
                   two(a);
          }two.js
              function two(a)
                      alert("two");
                  }But the function two() is not working.
How can I do this one??
regards,
Krish

I think there is a syntax error in line
document.write("<script type='text/javascript' src='/htmls/js/two.js'> <\/script>");
end tag <\/script> is wrong.

How to call inner class method in one java file from another java file?

hello guyz, i m tryin to access an inner class method defined in one class from another class... i m posting the code too wit error. plz help me out.
// test1.java

There are various ways to define and use nested classes. Here is a common pattern. The inner class is private but implements an interface visible to the client. The enclosing class provides a factory method to create instances of the inner class.
interface I {
    void method();
class Outer {
    private String name;
    public Outer(String name) {
        this.name = name;
    public I createInner() {
        return new Inner();
    private class Inner implements I {
        public void method() {
            System.out.format("Enclosing object's name is %s%n", name);
public class Demo {
    public static void main(String[] args) {
        Outer outer = new Outer("Otto");
        I junior = outer.createInner();
        junior.method();
}

How to call a specific method in a servlet from another servlet

Hi peeps, this post is kinda linked to my other thread but more direct !!
I need to call a method from another servlet and retrieve info/objects from that method and manipulate them in the originating servlet .... how can I do it ?
Assume the originating servlet is called Control and the servlet/method I want to access is DAO/login.
I can create an object of the DAO class, say newDAO, and access the login method by newDAO.login(username, password). Then how do I get the returned info from the DAO ??
Can I use the RequestDispatcher to INCLUDE the call to the DAO class method "login" ???
Cheers
Kevin

Thanks for the reply.
So if I have a method in my DAO class called login() and I want to call it from my control servlet, what would the syntax be ?
getrequestdispatcher.include(newDAO.login())
where newDAO is an instance of the class DAO, would that be correct ?? I'd simply pass the request object as a parameter in the login method and to retrieve the results of login() the requestdispatcher.include method will return whatever I set as an attribute to the request object, do I have that right ?!!!!

How to call c functions that expects c structs from java program?

i need to call from my java program to c functions that get
c structs as a parameters in their prototype.
as you probablly know java is not working with structs (classes only), so my question is how can i do it , i mean call the c functions that gets structs as parameters form java????

i believe your c function can accept a jobject and then inside your c function you have to translate that jobject into a c struct by using the jni methods.
the only reason your c function cant accept structs from java is because java does not have such structures. your c function can accept any data type that has been defined and a jobject has been defined.
if you have no control over the c functions that are being called, you need to write a wrapper function for those c function. the wrapper functions do the translation from jobject to a struct...then call the c other c functions.

How to call a static method of a class from another class?

Hello,
I have two classes in a package. The first one
package my package;
public class class1
protected static ImageIcon createIcon(String path)
The second one
package my package;
public class class2
private ImageIcon image1;
image1 = class1.createIcon("/mypath");
This does not work since class2 cannot load the appropriate image. Where do I have to define the ImageIcon variables in class one or two and do they have to be static variables?
Thanks in advance
Christos

If the two classes are in the same package, that will work, in fact. A trivial example:
package foo;
public class Foo1 {
     protected static String getString() {
          return "World";
// Note: Member of the same package
package foo;
public class Foo2 {
     public static void main(String[] argv) {
          System.out.println("Hello "+ foo.Foo1.getString());
}However, if they are in different packages that won't work - the protected keyword guarantees that only classes derived from the class with the protected method can access it: Therefore this will not work:
package foo;
public class Foo1 {
     protected static String getString() {
          return "World";
package foo.bar;
public class Foo2{
     public static void main(String[] argv) {
          System.out.println("Hello "+ foo.Foo1.getString());
}But this will:
package foo;
public class Foo1 {
     protected static String getString() {
          return "World";
package foo.bar;
public class Foo2 extends foo.Foo1 {
     public static void main(String[] argv) {
          System.out.println("Hello "+ foo.Foo1.getString());
}I think you should read up a bit more about packages and inheritance, because you're going to have a lot of trouble without a good understanding of both. Try simple examples first, like the above, and if you hit problems try to produce a simple test case to help you understand the problem rather than trying to debug your whole application.

node.add(child);
return (node);
The problem is when I run my program two windows open up. The original one with JTree1, and the panel and horizontal splitplane and another window with a new tree component that did get its objects from the database. My question is how do I "replace" the JTree1 with the new tree created from the second java file?
Or additionally, maybe I could set the data for JTree1 from within the second java file?

How to call external functions without a .DLL (just using a .H and .LIB file)?

Hello everyone,
actually I'm facing little difficulties on how to get an external function getting called from within CVI (Version 2009).
I was supplied with a .H file and a .LIB file to call an external function from within my CVI project. The .H file looks like this:
void exportedFunction(double *parameter);
As far as I know, the external function was written with MS Visual C++ 6.
So I tried to statically link to the extern al function like this:
- Add the .H file and the .LIB file to the CVI project
- #include the .H file where I needed to call the external function
- do the external function call
When building I get an unresolved external function call error from CVI so this seems not to be working.
I made some searches around and got up with two possible issues. Maybe one of you can help me get a bit further and get things working.
1) The "real" function code is located in the DLL file which was not delivered to me. Or is there a way to get things done (call external functions) just with a .H and a .LIB file (without any .DLL file included)?
2) The external function does not export according to "C-Style" rules. The function signature in the .H file shows no things like
extern "C" __declspec(dllexport) void __stdcall ...
Or maybe it's a combination of both issues (missing .DLL + wrong export style of function)?
I guess I could get around the wrong export style of the function when I manage to write a wrapper around the original function that actually uses C-Style exporting. But I guess I need the .DLL file for this try as well.
Thank you for your answers.
Best regards,
Bernd
Solved!
Go to Solution.

There is no need for the dllexport stuff. There is also the option for a static library without any DLL. But the 'extern "C"' is essential, because it forces the C++ compiler, which was probably used to compile the library , to use C calling convention.
If you can't ask the provider of the library to provide a version which was compiled using C calling convention the way to go is to write a wrapper with VC++6 around that library which reexports the functions using C calling convertion. Something like
extern "C" type0 myfunc1(type1 arg1, ...) {
return func1( arg1,...);
for every function , you need to use.
BTW. "unresolved symbol" is the linker error message, you can expect if you try to link C code against a library build with C++ calling convention.

How to call oracle function from ejb3

i'm trying to call an oracle query-function from ejb3.
The oracle function:
create or replace FUNCTION getSecThreadCount(secId in NUMBER,avai in NUMBER)

m_sql VARCHAR2(250);
BEGIN
m_sql:='select count(thrId) from thread where secId='|| secid||'

          Query query=manager.createNativeQuery("{call getSecThreadCount(?,?) }");
          query.setParameter(1, secId);

By the way, i have successfully called the function from hibernate. And i use oracle 11g, JBoss5 RC1.
Could anyone tell me how to call the function from EJB3?
Thanks.

}Basically you just ignore the refcursor outbound parameter.
This is a stored function, have yet to try outbound refcursor parameters in stored procedures...

How to call java function in javascript

Hello Everyone,
Can anyone tell me solution that:
How to call java function in javascript?
Thanks,
VIDs

You can't since Java is running on the server and javascript is running in the browser long after the Java side of things has finished executing. Assuming you're not talking about an applet here.
But you can make calls back to the server through Ajax. All you need is something like a servlet on the receiving end which you can invoke through Ajax; from that point you can execute any Java code you want.

How to call a function having OBJECT type as Return type

Hi,
I've the following function returning OBJECT type.

END;The above function got created successfully.
And i'm confused how to call this functions. I tried like below but didn't work
DECLARE
t_emp_info_1 GET_EMP_OBJ ;
BEGIN
   t_emp_info_1 := get_emp(7566) ;
   for i in 1..t_emp_info_1.COUNT
