<br> Pedro,<br><br> You need to use the same rulebase you used to create the working memory to deserialize it, as well as use the latest version of 4.0.x branch. I fixed this problem a few days ago.<br><br> IMPORTANT: we made an effort on improving/fixing serialization and dynamic rules use cases in 4.0.5. So, anyone using serialization and dynamic rules should upgrade to 4.0.5 as soon as it is released.<br>

Hi All,<br><br>I'm having the following error while deserialing a workingmemory object:<br><br>java.lang.ClassNotFoundException: com.oss.activation.rules.core.types.StepShadowProxy<br> at java.net.URLClassLoader$1.run(URLClassLoader.java:200)<br>

I don't know about com.oss.activation.rules.core.types.StepShadowProxy, I supose is a DROOLS generated class.<br>
<br>Any ideas of what could be wrong here?<br><br><br>Thanks!<br><span class="sg"><br>Pedro Costa.<br>
