RE: DWR 3.0 RC1 and WAS

I have come back to tryng to use DWR 3.0.0.0.116. I added the init-param you mentioned. I was not able to get it to work with DWR Java1.4 jar using retroweaver. However, it did work when using a jar I built thru retrotranslator. This appears to be working now with my environment of WAS 6.0/Java 1.4. Thx!


add in the DWR servlet  (web.xml)

<init-param>
  <param-name>scheduledThreadPoolExecutor</param-name>
  <param-value>org.directwebremoting.impl.AutoShutdownScheduledThreadPoolExecutor</param-value>
</init-param>

<init-param>
  <param-name>compressor</param-name>
  <param-value></param-value>
</init-param>


DefaultContainer.initializeBean:

java.util.concurrent.ScheduledThreadPoolExecutor

after retroweaver:

edu.emory.mathcs.backport.java.util.concurrent.ScheduledThreadPoolExecutor


And unset default compressor.

       
Sorry for my google's translation

I tried using http://retrotranslator.sourceforge.net/ against the base DWR 3.0 RC1 jar. I still end up with errors trying to run my web app when invoking DWR. Is anyone using this release with Java 1.4?
