Hi,

I was trying to use the rife continuations package to develop a simple
java example and came across a small problem.

I was trying to use a continuation to code a simple recursiveTower of
Hanoi program. Something akin to the wki example here

http://en.wikipedia.org/wiki/Tower_of_Hanoi.

I replaced the move with a pause() to break out of the recursion


hanoi(disks,...)
{
       if(disks > 0)
       {
           hanoi(disks-1,...);
           pause("Moving disk " ...);
           hanoi(disks-1, ....);
        }
}


When I do this it breaks out at the continuation, but upon reentry it
cauces a stack overflow problem. I am using an older version of the
rife continuaitons jar.

Any help would be greatly appreciated.

Cheers

Hi,

first, which version of RIFE/Continuations are you using?

Also, would you mind attaching the actual source code that you're  
using so that it can be run in a very easy fashion. If there is a  
problem, this drastically reduces the time to figure it out.

Thanks,

Geert

Hi Geert,

Thanks for your prompt reply. I do have a slightly older version - I think that it is version 1.4 which I downloaded previously and compiled myself. I have not tried the newer version as yet - has there been any major api changes or should the same code work?

I am enclosing the simple example I was trying to run. It actually runs three little tests

first - a simple Tower of Hanoi (no continuations)
second - a simple pause continuation example
third - the Hanoi with continuation which does demonstrate the problem under Rife 1.4

I did modify the code from your examples, but is is mostly a juggle around to put the same code in one single object called ContinuationObject. There is a build and run unix script that just need paths setting to build and run.

Thanks very much for any help you may provide.

Cheers

Hi Frederic,

I'll look at this later, but I strongly recommend that you try with  
the latest version of RIFE/Continuations, and maybe even one of the  
nightly builds. Most of RIFE's development lately has gone to the  
standalone continuations lib.

Best regards,

Geert

Hi Geert,

 

I am trying with a 1.4 JDK to put together a simple TestPause example. I have downloaded retroweaver and am getting the following error.

 

java.lang.NoSuchMethodError
        at com.uwyn.rife.continuations.ContinuationContext.clearActiveContext(ContinuationContext.java:114)
        at com.uwyn.rife.continuations.basic.BasicContinuableRunner.run(BasicContinuableRunner.java :227)
        at com.uwyn.rife.continuations.basic.BasicContinuableRunner.start(BasicContinuableRunner.java:87)
        at TestPause.testPause(TestPause.java:20)
        at mainTest.main(mainTest.java:13)
 

 

Is this due to a simple mistake. I am sorry to hassle you on this one. I really wanted to get a demo of the breaking out of recursion pattern together for teaching purposes. I have tried to rip apart your example, but the error isn't giving much away. This example I am trying is not a recursive example.

 

Any help would be much appreciated.

 

 

Cheers

 

again - sorry for having to keep coming back to you.

Hi Geert,

 

Continuing the saga this is what I did next. Looking at the posted software for continuations it dawned on me that you are using generics as part of the new distribution.

 

I am still trying to use 1.4 so I downloaded the generics 2.4 package from sun. I ran the examples and everything checked out ok.

 

I then tried to rebuild my app with your rife 1.4 jar and still got the same error NoSuchMethodError.

 

I then tried to build the continuations package that you distribute and received error about missing class files com.uwyn.rife.tools. etc... which are not included in the source continuations distribution.

 

I then tried to extract the missing class files from your rife.jar file and used the missing ones to try to rebuild a new app.

 

I am now getting errors about

 

com.tc.object.loaders class not found.

 

Can you please offer any help as I am unable to build a working continuations application for a JDK 1.4 with your distribution.

 

Cheers

 

P.S. any feedback would be appreciated

Hi Frederick,

why are you not simply using the JDK 1.4 version of RIFE/Continuations?

You can download it here. This should just work, no need to do  
retroweaver yourself or anything.
http://rifers.org/downloads/#rifecontinuations

Let me know how it goes.

I was originally using the 1.4 version of Rife with my JDK 1.4 and that was when the error I received was

 

java.lang.NoSuchMethodError
        at com.uwyn.rife.continuations.ContinuationContext.clearActiveContext(ContinuationContext.java:114)
        at com.uwyn.rife.continuations.basic.BasicContinuableRunner.run(BasicContinuableRunner.java :227)
        at com.uwyn.rife.continuations.basic.BasicContinuableRunner.start(BasicContinuableRunner.java:87)
        at TestPause.testPause(TestPause.java:20)
        at mainTest.main(mainTest.java:13)
 

 

Which was my original question. I started with the retroweaver etc. as an attempt to debug what the problem might be.

 

the example you have on your site has no main and also uses StringBuilder - this is why I started to use retroweaver and 1.4 does not support this class.

 

Like I said I had no real problems running with continuations under rife 1.4 except for the problem when I tried to use recursion. I can't seem to get 1.6 working under SDK1.4.

 

I do really appreciate your help with this though.

 

thanks

Hi Frederick,

why are you not simply using the JDK 1.4 version of RIFE/Continuations?

You can download it here. This should just work, no need to do
retroweaver yourself or anything.
http://rifers.org/downloads/#rifecontinuations

Let me know how it goes.

Hi Frederick,

I just committed a fix for this and in my local testing it should  
work. The JDK 1.4 jar was badly built. Please try this version and  
tell me how it works out for you:

http://rifers.org/downloads/rife/snapshots/rife-1.6.2-snapshot-20071108/rife-continuations-1.6.2-snapshot-jdk14-20071108.jar

Best regards,

Geert
