I found the solution.

I could implement a paragraph system now.

I shortly describe the most important things.

1. the spooler script should not have any carriage return

2. for a component the spooling works only with following link.

<img src='<% cc.getPage().getHandle() + ".spool." + cc.getQualident() + ".jsp" %>' width=200px>
Further on, in the "Component Definitions" for this script only "spool" should be written as globbing. Not "*spool" or "spool*".

This is also the reason, why we have cc.getQualident() after spool in the img-tag.

3. Further on it is important for a paragraph system to include the following initialization.

<%

Style actstyle = null;

%>

<cfc:initComponent cellId="body" componentId="/libs/Components/body">

<% actstyle = componentContext.getStyle(); %>

</cfc:initComponent>

<cfc:includeComponent cellId="body" componentId="/libs/Components/body" />

<cfc:includeComponent cellId="parsys"

                        componentId="/apps/emb/Components/parsys" />

4. in side the spooler script, you get the atom by:

                        String[] selectors = cqReq.getSelectors();

                        String qualident = selectors[1] + "." + selectors[2];

                        Container local = (Container) actpage.getElement(qualident);

                      Atom atom = local.getAtom("myImageSrc");

where "myImageSrc" is the atom.xml content definition.

The selcorts[2] is either "Single" or somthing like "parsys.0001".

5. In simple components, you need also this kind of code to initialize a edit bar.

<%

ComponentContext cc = (ComponentContext) request.getAttribute("componentContext");

ComponentInfo ci = cc.getComponentInfo();

%>

<cfc:editbar

                        parName="<%= cc.getContainerList() %>"

                        parNum="<%= cc.getContainerLabel() %>"

                        storagePre="<%= cc.getStoragePre() %>"

                        dialogAny="<%= ci.getContentDialog() %>"

/>

I hope this could help you creating the paragraph system.
