Hi,
Please help.
I have a need for a variable that is globally accessible from my
service implementation.
The normal way to do this in java is using statics AFAIK.
I am however painfully aware that i cannot use static variables in axis2.
They will be shared across all service instances, and persist after
the service call is done.
I believe this has to do with the axis2 classloader.
I really need to use some globally accessible variable in my service
implementation though! How do i go about?
My service implementation is a pojo BTW.
Greetings from Holland, Joek
Im registring the "global variable" as a property in the messagecontext.
Access to this "global variable/messagecontect property" is via a getter
and setter in a obeject that is a static itself.
Because its a static its acessible from anywhere in the code.
Testing reveils that the values do not get messed up.
PS a am aware that using globals is not a nice thing.
Example code:
the wrapper class for the get/set access
---------------------------------------
public class GlobalHolder{
// staticly instantiate itself
public static GlobalHolder globalholder = new GlobalHolder();
public int getGlobalVar() {
MessageContext messageContext =
MessageContext.getCurrentMessageContext();
return (Integer) messageContext.getProperty("globalvar");
}
public int setGlobalVar(int pValue) {
MessageContext messageContext =
MessageContext.getCurrentMessageContext();
messageContext.setProperty("globalvar", pValue);
}
}
in the Main class
-----------------
public class Mainclass {
public Mainclass(){
//constructor: make sure the property exists to avoid null pointers
GlobalHolder.globalholder.setGlobalVar(0);
}
public int myMethod(){
// go about getting and setting it everywhere in the code.
GlobalHolder.globalholder.setGlobalVar(700);
return GlobalHolder.globalholder.getGlobalVar();
}
}
