It seems to be that the classloader parent of 'WAR classloader' is = 'EJB

WebService.
But this WAR isn't it. Only it calls EJB com= ponents be in another server=20

But the problem isn'= t during EJB components calls, but when iBatis load

Why I have to delegate to parent classloader ( EJB classloader )= to find jars=20
stored into <server-instance>/lib from my WAR file ?

Interesting - that means that the iBATIS JARs are loaded by a parent c= lassloader to the WAR classloader.  So the iBATIS jars must = be installed somewhere in the application server's classpath.  That's = probably not the best arrangement.=20

1. Right

2. Right.  This is v= ery rare because doesn't find iBatis jars, but yes another jars

I found a workaround but I don't know why works !!

The solution is = add=20

<class-loader delegate=3D'true'>

into sun-web.xml


I'm confused.  Are you saying:
 
1. It works if you package this into an EAR and the iBATIS jar files a= re in the EAR
2. It does not work if package this into a standalone WAR and put the = iBATIS jar files in web-inf/lib
 
???
 
If the app cannot find jar files in web-inf/lib, it is not an iBATIS p= roblem - something else is seriously wrong with your WAR (likely) or applic= ation server (unlikely).

Thanks for the answer, but that is not th= e problem.

It's a problem about casting:

Well, I have debugge= d the iBatis source and I have seen that the problem is in

com.ibat= is.sqlmap.engine.builder.xml.SqlMapConfigParser.java

when cast

DataSourceFactory dsFactory =3D (DataSourceFactor= y) Resources.instantiate(type);

(  in   addNodelet &q= uot;/sqlMapConfig/transactionManager/dataSource/end()" )

The 't= ype' value is '=20 com.ibatis.sqlmap.engine.datasource.
JndiDataSourceFactory' in my applic= ation

Indeed, if I do

com.ibatis.sqlmap.engine.datasource.Jn= diDataSourceFactory dsFactory =3D (com.ibatis.sqlmap.engine.datasource.Jndi= DataSourceFactory ) Resources.instantiate(type);

the ClassCastException happens again= .

Only with

JndiDataSourceFactory dsFactory =3D new JndiData= SourceFactory()

doesn't happen.


I guess that the source e= rror is in the way that the objects are instanciated by classloader in=20 com.ibatis.common.resources.Resources.java , but I dont know why.

I = tried to allocate ibatis JAR files into WEB-INF/lib, but WAR doesn't find c= lasses.

Ummmm
Try this:
 
<transactionManager type=3D"JDBC">
 &nbs= p;  <dataSource type=3D"JNDI">
  &= nbsp;   <property name=3D"DataSource" value=3D"= java:comp/env/jdbc/datasource"/>   =20
    </dataSource>
  </transactionManag= er>
