Struts Update: 1.1 beta 3 to 1.1 RC1 While upgrading Hibernate last night and this morning, I also upgraded Struts. Now I'm having some issues there, so I'd better document those too. First of all, the following line doesn't seem to be rendering any client-side JavaScript anymore:

<html:javascript formName="resumeForm"
      dynamicJavascript="true" staticJavascript="false"/>

Update 1: Nevermind, it seems my Internet connection went dow while starting Tomcat. Since the Digester couldn't validate the Struts' XML configuration files with their respective DTDs, it stopped them from loading.

Update 2: This turned out to be a legitimate issue. Adding cdata="false" to the above tag enabled the browser to see the JavaScript by removing the "<![CDATA[" after <script type="text/javascript">

Revisiting the Hibernate upgrade, I needed to add dom4j.jar to WEB-INF/lib to solve java.lang.NoClassDefFoundError: org/dom4j/Node.

Now I'm getting:

java.lang.NoClassDefFoundError
	at net.sf.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:571)

What the @#$*%#? hibernate2.jar is in WEB-INF/lib??

Update 3: I had to add cglib.jar to WEB-INF/lib as well. Now back to an issue I'm having with the Validator where client-side validation is working when I click "cancel" (as in, it's disable), but server-side is kicks in. Argghhhh!

Update 4: I found an issue (via the struts-user list) about using the Validator with LookupDispatchAction. It basically doesn't allow you to control validation on a method level, so I've hacked the following workaround.

I changed <html:cancel> to be <html:button> and added onclick="cancel()", where cancel() is the following JavaScript method:

<script type="text/javascript">
function cancel() {
    location.href = '<html:rewrite forward="cancelUser"/>';
}
</script>

The "cancelUser" forward points to "/editUser.do?action=Cancel", which is an action-mapping that doesn't have validation (validation="false") and this hits the "cancel" method on UserAction and routes appropriately.

Phew - I'm beat. I never realized being an upgrade-happy-keyboard-monkey could be so much work! Posted in Java at Feb 24 2003, 11:10:46 AM MST 4 Comments

I think if 2 fields have a relation it's quite easy add them into a bean (i.e. Login) that contains both and then make a usual validator (both JavaScript and Java) checking interrelation??? Example: We have 2 dates having Date1 > Date2 So WtoDates.Date1 WtoDates.Date2 No we can use an empty property (i.e. WtoDates.test) just to call the validator Opinions???
