Object not waiting for other to finish its job

Hi everyone,I have two Java classes. One of them is a GUI and the other one is a complex java class with processes that have to work for a little long time. In the GUI when a button is pushed the object of the second class is created and a function of it is called. In this function the program gets stuck in the line "wait();". How can I get rid of this problem? I hope i could express my problem clearly. For i e (I think it will be better if I give an example)*** Class-1 ***Object_2 callFunction();...*********************Class-2 ****void callFunction(){. wait(); // program stops at this point and waits for ever without giving any //error message..} The code is like below.** object 2 **// do some stuff that takes long time to executewait();** end of object 2 **The object2 is waiting for the process to come to an end. The other object(1) that has created this object(2) is supposed to wait for this object(2) too. But it(1) doesn't wait. That is the problem.. Do you recommend me to use notify() instead ??By the way the implementation of the class 2 was written by someone else and it works correctly if its main() function is executed. What i want to do here is to try to call and execute this object from an another object. Edited by: ccelgun on Nov 11. 2007 10:15 PM I have bad news and good news :)Bad news is that problem was not because of the waiting process so this topic was totaly useless. Good news is that i found the problem and fixed it. It was because of the path in which the object 2 was working. I should have changed the path from object 1's path to object 2's path after calling the object 2.. Thanks anyway... And sorry for disturbing..

Avoiding the startup time for webservice xml serialization

In the build tab of a communicate’s properties is an option called “Generate serialization assembly” turn it to “On” to theoretically improve performance. the wsdl is 2 megabytes. Startup takes several minutes before anything happens. And it is mostly the startup time causing problems things go smoothly after that. While trying to alter things I found this single line causing most of the decelerate: And it was only the first time that the webservice was initialized that the delay happened. I started searching and ran across a knowledgebase bind explaining how to create an XmlSerializers assembly. Apparently the XmlSerialization process usually generates code at runtime and this can take a while. The bind explained how to pregenerate this code to deliver startup time later. I tried it it didn’t seem to back up all that much and it was a hurt to fit into the create process. I later found. It was a new feature in net 2.0 that I bequeath hearing about. Then I open. I never noticed it before (maybe because I had to scroll down the properties page) but there was a simple drop drink in Visual Studio for this. Switching it from Auto to On built the assembly automatically! Once enabled build time became much longer and startup times were a little exceed. The change wasn’t as dramatic as I had hoped. I think from here I’m going to create a much smaller specialized web service since I undergo access to the web function forge and we’re only using a handful of the 800 methods available.

Serialization - ClassNotFound Exception ?!

First hallo every one :Second:i have a problem with deserialization i have here 3 machines talk to each others through objects (Called MessageX) this come about through sockets and Object Input & Output Streams now class MessageX is inside the case of each schedule of the 3 machines but once one of them acquire an disapprove at casting it back to the MessageX type i get a nice Exception saying that ClassNotFound Exception so now does that mean that i cant talk through objects [i guess not] and if i can Object serialization is a way to persist ur objects and it is allowed. It depends upon how u have defined MessageX class. Go through the given link for more details http://java sun com/developer/technicalArticles/Programming/serialization/ if i can how i can overcome the categorise not found exception ?! The machine where you got the exception doesn't have the categorise named in the exception available in its classpath. It's as simple as that. Hi. If you are keeping MessageX categorise in same jar as the executing categorise which tries to cast it. Other wise atleast runthe program in the machine which you got CCE with class path added with the location of MessageX classI hope this will solve your issues.

Query Regarding serializable interface.

Hi,I undergo a query regarding serializable interface. I understood basic concept of serializable interface. If we are developing application how ordain i identify which class to apply as serializable interface. My assumption is that we undergo to apply serializable interface whenever object is transfered from one communicate to other then only implement serializable interface is this change by reversal?Second assumption is that as we create verbally server align programming i e application which run under hit JVM then there is be to that.. is this change by reversal? Any object that has to "cross the equip" needs to be Serializable. Serializable is just a marker interface indicating objects of a class implementing Serializable can be serialized. The JVM has a standard mechanism for (de)serialization that works quite come up. In case you have special needs you can implement the special readObject() and writeObject() methods. Objects that live within a hit JVM be not be serializable (generally speaking). If you be to send objects from one JVM to another they have to be serializable. Please construe the JAvaDoc for Serializable carefully especially the parts on how objects are re-created when they are deserialized at the receiving end.

ThreadPool$Worker run(ThreadPool java:593) thanks for say,actually i m not sending key across N/W i m just storing that key on server and try to fetch that key and this is full label i written to get SecretKey and i be to know how to displace key across n/w because when we use Serialization we have to create file of that disapprove and at the other end we get that data from the same file bt i dont want to create file so is there any another way to go key without act register of that key??? You can delete the oos flush() but the final change state must be oos close() not fos change state(). So the file is alter and must be recreated. Re the communicate you shouldn't be sending secrets across a plaintext connection. Use HTTPS. I've already seen that code and I've already told you that you've created the file incorrectly with the writing label. You have to fix that not just repost some other label. This is the reading code and apart from the unused URL code that apparently just wastes time. I don't see anything wrong with it. InputStream uin=null; try { URL u = new URL("http://hostName:8080/ServerSide/secret key"); URLConnection uc = u openConnection(); uc cerebrate(); uin = uc getInputStream(); } catch (IOException e) { //...} ObjectInputStream oOs2 = new ObjectInputStream ( uin) ; SecretKey key2 = ( SecretKey ) oOs2 readObject();
