Hi!,
I'm having a little problem with Digester's CallMethodRule: it doesn't
call the method.
The XML file I try to parse is:
---
<configuration>
<pages>
<page path="/index.htm" class="test.TestPage" />
<page path="/hello.htm" class="test.HelloPage" />
</pages>
</configuration>
---
The Java code I'm trying to use for parsing the configuration:
---
...
Digester digester = new Digester();
digester.addObjectCreate("configuration", "test.Configuration");
digester.addObjectCreate("configuration/pages/page",
"test.PageConfiguration");
digester.addSetProperties("configuration/pages/page", new
String[]{"path", "class"}, new String[]{"path", "className"});
digester.addCallMethod("configuration/pages/page", "freeze");
digester.addSetNext("configuration/pages/page", "addPageConfiguration",
"test.PageConfiguration");
Configuration configuration = (Configuration)digester.parse(reader);
---
The problem is that the freeze() method of instantiated
PageConfiguration objects isn't ever called (which results to that the
Configuration's addPageConfiguration(PageConfiguration) throws an
IllegalStateException). How I should fix this? I'm using the version 1.7
of Digester.
Are you sure the problem isn't the *order* that methods get called for
element "configuration/pages/page" rather than that the freeze method
doesn't get called at all?
I suggest reading the FAQ entry titled "How do I get CallMethodRule to
fire before SetNextRule?" here:
