How to call JSP function from onClick Action

Hi
I am trying to call a jsp function, onclick of a checkbox. This jsp function will in turn connect to the database and gets related information. I dont want to submit the data inorder to avoid posting and getting of huge data. Is there a simple way to call a jsp function from the users onClick action.
Appreciate anyones help!!!
Thanks alot
Joe

So, i have to submit the form to call the jsp function. Basically yes.
Sorry for the shortness of the answer, but I am pretty sure we have had this conversation (or one very much like it) before.
Java/JSP runs on the server, generates an html page, and stops running.
Javascript runs on the client in the web browser, once the page is loaded.
You cannot call java code from javascript.
The only way you can run java code again is to make a request - either by submitting a form, or clicking a link.
If you don't want to refresh the current page, you CAN get tricky with javascript and multiple frames. You submit to another frame, and when it loads, it uses javascript onload event to call back and modify the main frame. Its tricky to get going, and very easy to break, so I don't normally recommend it.
Good luck,

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)
RETURN SYS_REFCURSOR is cur SYS_REFCURSOR;
m_sql VARCHAR2(250);
BEGIN
m_sql:='select count(thrId) from thread where secId='|| secid||'
and thrAvai='|| avai;
open cur for m_sql;
return cur;
END;
I'v tried several ways to call it,but all failed:
1. the calling code:
public Object getSectionThreadCount(int secId,int avai){
          Query query=manager.createNativeQuery("{call getSecThreadCount(?,?) }");
          query.setParameter(1, secId);
          query.setParameter(2, avai);
          return query.getSingleResult();
but i got the exception:

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 a function from asp

Hi!, I'd like to know how to call a function from an asp page. I've written:
set rs = server.createobject("Adodb.recordset")
rs.open "call dbo.sf_Obt_Des_Producto ('0000161')",Conn
if err.description <> "" then
response.write ("No se pudo! :(")
else
response.write ("rs: " & rs(0))
end if
rs.close
set rs = nothing
but there is an error:
ORA-06576: not a valid function or procedure name
Please is very urgent!!!
Thanks.
Angie.

You need to use the syntax "{call <procedure_name>}".
The {call } syntax tells the OLE DB provider that it needs to translate the call into whatever the database's procedure calling syntax is. This means that even though different databases have different syntax for calling stored procedures, your OLE DB code can be run against any of them without changing.

How to Call a function from FMS to AS3

Hi,
I am using Windows operating system, Flash CS3 and FMS 3.5.
I am new to Action Script 3.0 But I am good in Action Script 2.0.
I am trying to call a function declared in Action Script 3.0
from FMS. here I have declared it as follows.
In FMS I am calling a function as
application.onConnect(client){
client.call("informServer");
In Flash AS 3 I have declared this function as follows.
var nc = new NetConnection();
// Now here I declare function
nc.addEventListener("informServer", informServerHandler);
nc.connect("rtmp://localhost/abc");
private function informServerHandler(evt){
trace(" Till here Done ");
So When I execute Flash file then it connects to FMS and also
in NetStatus event of NetConnection I got Connected.
But Then I got Error in Flash as
Error #2095: flash.net.NetConnection was unable to invoke
callback informServer." error=ReferenceError: Error #1069: Property
informServer not found on flash.net.NetConnection and there is no
default value.]
Please tell me Have I not declared the Function in AS 3
properly or I am doing something wrong. Please Some one help me...
Thanks in advance.

You can't add an event listener, as your custom method is not
a method of the NetConnection class. Instead, you can assign
methods to the NetConnection's client property:
nc.client.informServer = function(){
// do something
If you want to just define your functions in a class, you can
make the class the value of nc.client:
class blah{
function blah(){
var nc:NetConnection = new NetConnection()
nc.client=this;
//connect, status listener, etc
private function informServer(){
// Now this function is invoked, since the class is the
NetConnection's client.
}

Yes. As serlank showed, you can just call the function easily in scriptlet tags
However the whole point of a tag library is to avoid the use of scriptlets.
Seeing as you can't use functions, is just to do it as a standard tag.
ie in your jsp
<login:verify name="<%= userName %>" password = "<%= password %>" resultVar = "status"/>
<c:choose>
<c:when test="${status == 'InvalidU'}">
    <c:set var="nextPage" value="InvalidUserName.jsp"/>
</c:when>
<c:when test="${status == 'InvalidP'}">
    <c:set var="nextPage" value="InvalidPassword.jsp"/>
</c:when>
</c:choose>In your case, this tag in the tld would possibly look something like this.
You would then have to write a tag handler class that would call the function you want.
<tag>
<name>verify</name>
<tagclass>com.tags.login.Verify</tagclass>
<teiclass>com.tags.login.VerifyTEI</teiclass> (if required)
<bodycontent>JSP</bodycontent>
// name attribute
<attribute>
      <name>name</name>
      <required>true</required>
      <rtexprvalue>true</rtexprvalue>
    </attribute>
// password attribute
    <attribute>
      <name>password</name>
      <required>true</required>
      <rtexprvalue>true</rtexprvalue>
    </attribute>
// result variable to return a response from the tag.
<variable>
    <name-from-attribute >resultVar</name-from-attribute >
    <variable-class>java.lang.String</variable-class>
    <declare>true</declare>
    <scope>AT_END</scope>
</variable>
</tag>Hope this helps some, and doesn't confuse too much :-)

How to call JSP page from applet?

I have some page1.jsp from which I call applet.
User works with this applet but some information does not in date inside applet.
So user click on some component at applet (some button etc.) and now I would like to do this:
1) open new window;
2) call page2.jsp at this new window.
The reason is that page2.jsp will read some data from database and then displays it in HTML inside page2.jsp itself. It is not necessary to pass these date back to applet for displaying them inside of applet.
So user then can have 2 windows: page1.jsp with applet and page2.jsp with some details information.
But I DO NOT know how to call page2.jsp from applet, and do ti in a new window. Is it possible and how?

return;
And I always get "undefined symbol: testPhase1__Fddd" error!
what is the problem here? thanks alot!
Jim

Basically - you are already are compiling a c file. Replace that c file with all the c files.
Specifically it depends on the OS, compiler and how you are compiling
For windows add it the project or compile each file and then add the object fill to the link line.
For unix add the other c files in to the compile line the same place you have the current C file.

How to call a function from one viewmodel to another viewmodel

Hi ,
How to call a funtion of another viewmodel in a viewmodel . This help would be much appreciated
Thank You
Jeevan Vinay

Please close your previous threads by marking helpful posts as answer before you start a new one.
You need to either get a reference to the second view model from the first one or you could use some kind of messenger or event aggregator to pass a message from the first view model to the second one. The latter approach is preferable as it doesn't create
a tight coupling between the two view model classes.
Please refer to my blog post for more information and an example of how to use Prism's EventAggregator to do this:
http://blog.magnusmontin.net/2014/02/28/using-the-event-aggregator-pattern-to-communicate-between-view-models/
You will need to download and install Prism to be able use the EventAggregator class:
https://www.nuget.org/packages/Prism/
Another popular framework out there is the MvvmLight which contains a Messenger class that works pretty much the same. Andy has provided and example of how to use this one:
http://social.technet.microsoft.com/wiki/contents/articles/26070.communicating-between-classes.aspx
You can download and install MvvmLight via Nuget (Tools->Nuget Package Manager->Package Manager Console in Visual Studio):
https://www.nuget.org/packages/MvvmLight/
Please remember to close your threads by marking all helpful posts as answer and then start a new thread if you have a new question.

How to call a function from a different script object?

Hi All,
Here is the scenario,
I have 2 script objects A and B .
In script object A i have a function called "funcA" and
in script object B i have a function called "funcB"
Now I want to call funcA from funcB which is not happening.
I tried doing
A.funcA();
inside funcB , but not able to access.
Kindly help.
Thanks
Abhiram

Hi Abhiram,
Just a guess - try including the root node/node reference above the script object.
form1.A.funcA();
What does the JavaScript Console say when firing the function? Are there any errors?
Your script objects can contain multiple functions. So you could move funcA() and funcB() into the same script object. This will make it easier.
