apparently the call function does work but when instantiating my apple it
gets a java.lang.LinkageError:
I've adjusted the
org.apache.cocoon.components.flow.apples.ApplesProcessor:
private AppleController instantiateController(String className)
throws Exception {
// TODO think about dynamic reloading of these beasts in future
// classloading stuf et al.
if (getLogger().isDebugEnabled())
getLogger().debug("ApplesProcessor->instantiateController() -
className='"+className+"'");
try {
Class clazz = Class.forName(className);
Object o = clazz.newInstance();
return (AppleController) o;
}
catch (LinkageError e)
{
if (getLogger().isDebugEnabled())
getLogger().debug("ApplesProcessor->instantiateController() -
LinkageError msg="+e.getMessage());
}
return null;
}
this generates the following logging;
(2006-02-23) 14:19.15:296 ApplesProcessor: ApplesProcessor->callFunction()
- className='be.sofico.MyApple'
(2006-02-23) 14:19.15:296 ApplesProcessor:
ApplesProcessor->instantiateController() - className='be.sofico.MyApple'
(2006-02-23) 14:19.15:312 ApplesProcessor:
ApplesProcessor->instantiateController() - LinkageError
msg=org/apache/cocoon/woody/formmodel/Widget
so it must be something inside the class MyApple that incorrectly links to
the old Woody Widget class but looking at the import of my class this
should not be possible:
import org.apache.cocoon.ProcessingException;
import org.apache.cocoon.i18n.I18nUtils;
import org.apache.cocoon.components.flow.apples.AppleController;
import org.apache.cocoon.components.flow.apples.AppleRequest;
import org.apache.cocoon.components.flow.apples.AppleResponse;
import org.apache.cocoon.environment.Session;
import org.apache.cocoon.forms.FormContext;
import org.apache.cocoon.forms.FormManager;
import org.apache.cocoon.forms.binding.Binding;
import org.apache.cocoon.forms.binding.BindingManager;
import org.apache.cocoon.forms.event.FormHandler;
import org.apache.cocoon.forms.formmodel.Form;
I've recompiled all the classes correctly; I'm assuming that I don't need
the deprecated woody-block to run the cforms-block ???
Pls, any help is welcome,

map:call function
I'm currently upgrading from 2.1.4 to 2.1.8 and converted all Woody stuff
to CForms stuff but when calling the following sitemap snippet I'm getting
the error below.
sitemap snippet:
<map:flow language="apples"/>
...
<map:match pattern="welcomepage">
<map:call function="be.sofico.myApple">
...
</map:call>
</map:match>
the stacktrace snippet:
java.lang.NoClassDefFoundError: org/apache/cocoon/woody/formmodel/Widget
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:141)
at
org.apache.cocoon.components.flow.apples.ApplesProcessor.instantiateController(ApplesProcessor.java:108)
at
org.apache.cocoon.components.flow.apples.ApplesProcessor.callFunction(ApplesProcessor.java:52)
at
org.apache.cocoon.components.treeprocessor.sitemap.CallFunctionNode.invoke(CallFunctionNode.java:138)
so following the ApplesProcessor.java:108 it should make a new instance
(thru reflecting) from the "be.sofico.myApple" string "classname" but
apparently it is trying to make a Widget object using the old woody
package. I don't even understand why it should make a CForms widget at
that moment.
any help is welcome,
Regards,
Gunter D'Hondt
