Still Ajax and Struts 2
I,
I wanna run this type of example app :
http://www.planetstruts.org/struts2-showcase/viewSource.action?page=/ajax/remotediv/example1.jsp
:
<s:div
13: id="once"
14: theme="ajax"
15: cssStyle="border: 1px solid yellow;"
16: href="/AjaxTest.action"
17: delay="5000"
18: loadingText="loading...">
19: Initial Content
</s:div>
In other word, a basic ajax component that allows a refreshment of only a
part of my page.
But I didn't get how to write the corresonding action and action mapping.
For the moment I've tried to put a "success" return in my action ( is it
enough ?), but I don't see what to put in my action mapping (i mean inside
the <action name="blablabla" ...> tag. If I put nothing, of course it's
wrong.
If I only put a success-type result, It creates an infinite loop (always
displays "loading").
Can sobdy help please?

Ok thank you very much that works !
My mistake was in the mapping, where I redirected to the same jsp as the one
where I've putted the div tag.
Actually, I had to write a simple jsp in ordrer that it works.
Otherwise,
I'm always having the error message on my console :
SEVERE: Error setting expr 'dojo.transport' with value
'[Ljava.lang.String;@9de832'
ognl.OgnlException: target is null for setProperty(null, "transport",
[Ljava.lang.String;@9de832)
at ognl.OgnlRuntime.setProperty(OgnlRuntime.java:1624)
wich is repeated till the infinite when I choose to refresh my "div ajax"
component. Can this be dangerous in term of performance, etc ?
thanks.

Re: Still Ajax and Struts 2
Posted by Musachy Barroso <mb...@wfscorp.com>.
What is happening is that there is an error on the request, probably the
action mapping is wrong, and it is returning a page with the error, but
that page has the same menu as showcase, that's why your are seeing it
twice. Put the full url for the action on the address bar, after you get
that to show the right page (what you expect to see in the div tag),
then try the div.

Re: Still Ajax and Struts 2
Posted by walidito <wa...@sgcib.com>.
I don't hink I'm adding anything.
Here is my code :
the action :
public String execute() throws Exception
{
return SUCCESS;
}
the struts.xml:
<action name="AjaxTestAction"
class="dashboard.actions.AjaxTestAction">
<result>/JSPs/Menu.jsp</result>
</action>
and the jsp :
<head>
...
<s:head theme="ajax" debug="false"/>
...
</head>
<body>
<s:div
id="once"
cssStyle="border: 2px solid red;"
href="%{ajaxTest}"
theme="ajax">
hhookayy
</s:div>
</body>
I know it's working on the shwocase, but my app is not working... Since the
showcase action and struts sources are not available...
What I see on my screen is the "top" of jsp that is written twice, in fact,
the top html is loaded once (normal), but after the action call, the top is
written another time, I don't know why... Moreover, the eclipse console
displays the same error (dojo.transport) again and again...

Re: Still Ajax and Struts 2

That needs to be fixed in struts, this is the jira ticket:
https://issues.apache.org/struts/browse/WW-1551
from showcase:
<s:div
id="once"
theme="ajax"
cssStyle="border: 1px solid yellow;"
href="%{ajaxTest}">
Initial Content</s:div>
That should load the div only once.

Re: Still Ajax and Struts 2
Posted by walidito <wa...@sgcib.com>.
Hi,
Actually, I get this error both in my eclipse "console" and in my web page
(debug enabled).
First of all here is the "jsp" code that I use:
<s:div
id="reportDivId"
cssStyle="border: 2px solid red;"
href="/AjaxTestAction.do"
theme="ajax"
delay="3000"
errorText="There was an error"
loadingText="loading...">
<s:property value="count"/> @ <s:property value="serverTime"/>
<br/>
</s:div>
this is the redundant error that I get on my eclipse console :
-SEVERE: Error setting expr 'dojo.transport' with value
'[Ljava.lang.String;@e8f27e'
ognl.OgnlException: target is null for setProperty(null, "transport",
[Ljava.lang.String;@e8f27e)
at ognl.OgnlRuntime.setProperty(OgnlRuntime.java:1624)
at ognl.ASTProperty.setValueBody(ASTProperty.java:105)
at ognl.SimpleNode.evaluateSetValueBody(SimpleNode.java:177)
...
and after a first call of the action I get this on my browser :
....
DEBUG: widget ID collision on ID: reportDivId
...
I think this must come from the fact that with my code, I want (for the
moment) that the action is called only once, but in fact after the 3000 ms
delay, the action is called again, and it returns a success to the same
"<div id=reportDivId ...>", that's why there is a collision. Isn't it?
If so, what it is the way to make sure that my div tag doesn't recall my
action more than once ?
Moreover, how come th samples of the Showcase does NOTprovide the
corresponding action and struts.xml files. Because it works on the showcase,
so with the right code it should work "at home"
thanks.

You are seeing that error in your server logs right? There's a couple of
things that we still need to fix for this integration between Struts and
Dojo, but the application should work anyway.

I think you should take a look at the Struts2/Webwork tutorials
http://www.opensymphony.com/webwork/wikidocs/Tutorial.html and
http://struts.apache.org/2.x/docs/tutorials.html
If you look at the showcase code you will see this for the AjaxTest action:
in struts-ajax.xml:
<action name="AjaxTest"
class="org.apache.struts2.showcase.ajax.AjaxTestAction">
<result>/ajax/AjaxResult.jsp</result>
</action>
in AjaxTestAction.java:
public class AjaxTestAction implements Action, Serializable {
private static int counter = 0;
private String data;
public long getServerTime() {
return System.currentTimeMillis();
}
public int getCount() {
return ++counter;
}
public String getData() {
return data;
}
public void setData(String data) {
this.data = data;
}
public String execute() throws Exception {
return SUCCESS;
}
}
and AjaxResult.jsp:
<%@ taglib prefix="s" uri="/struts-tags" %>
<%
request.setAttribute("decorator", "none");
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the
proxy server
%>
Result: <s:property value="count"/> @ <s:property value="serverTime"/>
<br/>
<s:property value="data"/>
