Thanks Jeff, following your suggestions I investigated those arcane classloader issues and I came up with a partially satisfactory solution.
Let me try to explain what I was trying to do: First I "bundled" all iBatis jars and the MySQL J/Connector jar into an Eclipse plugin, by using the "New Plugin from Existing Jars" wizard. I called it org.apache.ibatis. Then I created my sample RCP test application to test the iBatis connection and normal db activities, I called it fr.grenoble.db. In this plugin I generated all the abator artifacts: the sqlmaps, the java classes and the dao classes. After that, in this db plugin I created a simple Application.java whose only job is to insert a row in a table of the database. But initially I kept getting those "resource not found errors" during runtime, so, after your suggestion, and digging into the documentation, I found that I would've probably needed to use some "buddy classloading" spells. So I added the line: Eclipse-BuddyPolicy: registered into the MANIFEST.MF of the org.apache.ibatis "plugin", and the line: Eclipse-RegisterBuddy: org.apache.ibatis into the MANIFEST.MF of the fr.grenoble.db plugin. By doing that, the "resource not found" issue seemed to be solved. But now, I get another error: when I try to use the sqlMap.insert("abatorgenerated_insert", se); in my Application.java class, I get this error message: !ENTRY org.eclipse.osgi 2006-03-21 16:46:38.87 !MESSAGE Application error !STACK 1 com.ibatis.sqlmap.client.SqlMapException: There is no statement named abatorgenerated_insert in this SqlMap. at com.ibatis.sqlmap.engine.impl.SqlMapExecutorDelegate.getMappedStatement(SqlMapExecutorDelegate.java:288) at com.ibatis.sqlmap.engine.impl.SqlMapExecutorDelegate.insert(SqlMapExecutorDelegate.java:424) at com.ibatis.sqlmap.engine.impl.SqlMapSessionImpl.insert(SqlMapSessionImpl.java:81) at com.ibatis.sqlmap.engine.impl.SqlMapClientImpl.insert(SqlMapClientImpl.java:58) at fr.grenoble.db.Application.run(Application.java:41) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:226) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:376) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:163) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.core.launcher.Main.invokeFramework(Main.java:334) at org.eclipse.core.launcher.Main.basicRun(Main.java:278) at org.eclipse.core.launcher.Main.run(Main.java:973) at org.eclipse.core.launcher.Main.main(Main.java:948) However, I can see that statement in the system_element_SqlMap.xml file: <insert id="abatorgenerated_insert" parameterClass="fr.grenoble.db.model.SystemElement"> <!-- WARNING - This element is automatically generated by Abator for iBATIS, do not modify.

Any clue? Thanks again!
