error in @Override while chaning JDK1.6 to the JDk1.5

Hello

I'm getting following error when migrating JDK1.6 to JDK1.5.

Several markers on this line
-implements org.quartz.Job.execute
-Execute (JobExecutionContext) of type TransferFiles method must override a superclass
method

I have a class that implements the interface to work with a method execute (JobExecutionContext framework). I'm override of this method in one of my class using the @Override annotataion.

It works quite well in JDK1.6, but when migrating to JDK1.5 it says error above.

Kindly help me in this regard.

Thank you

Here, I have two suggestions from eclipse.

1. Create method execute in super type ToolConstants
2. remove the @Override annotation.

but I have the same method within an interface named as Job.

How is whatever it is?

So after removing the annotation @Override

I'm getting the following exception to the runtime.

javax.servlet.ServletException: the Servlet execution threw an exception

first cause

java.lang.NoClassDefFoundError: javax/activation/DataSource
fileTransform.FileTransServlet.doPost(FileTransServlet.java:52)
javax.servlet.http.HttpServlet.service(HttpServlet.java:647)
javax.servlet.http.HttpServlet.service(HttpServlet.java:729)

So why do you think that this exception is in no way related to the annotaton @Override on execute()? It is not the case!

What happened here is that your fixed the problem (by removing the "@Override") and could continue on your way to get your code to run on Java 5. Further along the road, you encounter another problem (not related). This does not mean that your first fixing problem caused to the other. She has just discovered it (i.e. the first problem you kept from seeing each other earlier).

Something in FileTransServlet javax.activation.DataSource references, which is a type that was introduced in Java 6 and did not exist in Java 5 (you can include the Java Activation jar files needed to get access to this guy even in Java 5).

  • error message trying to run a clean boot "an access error was returned while trying to change a service."

    While trying to solve a problem with IE 8, I have a problem trying to run a clean boot.  When I start up I get a message on change in the config file. Click ok and sys config is displayed. Now, if I make a modification, OR not, I get an error message - "an access error was returned while attempting to change a service. You may need to log on using an administrator account to make the specified changes. "First of all I am logged on as administrator, secondly I get this error even when I select"normal start ". I used the clean boot before without problem.  Any ideas?  I am running win xp sp3.  I started having problems after the sp3 upgrade.

    Given that you are not using the standalone SP3 Installer AND since McAfee was working at the time of installation, that's what I'd do (well, I would do it only if I was almost 100% convinced there was no malware on my system):

    1. download the McAfee removal tool.

    2. download the installation file for the free version of Avira AntiVir.

    3. download the standalone SP3 Installer.

    4. download the standalone installer of IE8.

    5. physically disconnect from the Internet.

    6 turn off the automatic updates (temporarily).

    7 uninstall McAfee.

    8 run the McAfee removal tool to make sure that all other loose ends are supported.

    9 Uninstall SP3.

    10. run the system restore, select the before date SP3 has been installed.

    11 uninstall IE8 (and IE7, if necessary). Reason: It is important to be at the level of IE6.

    12 install the SP3. Reset.

    13 Installing IE8. Restart twice.

    14 install AntiVir.

    15 re - connect to the Internet.

    16. download and install the update of AntiVir.
