Using json in Struts 2.1.8.1
Hi All,
I'm having following Action
----------------- Action(Begin) -----------------
public class AutocompleteField extends ActionSupport {
private String city;
private Map<String,String> json;
public String execute() throws Exception() {
return SUCCESS;
}
public String getCities() throws Exception() {
json = new HashMap<String,String>();
if(city != null && city.length() > 0) {
CityDao dao = new CityDao();
List<City> cities = dao.getCitiesStartingWith(city);
for(City city : cities) {
json.put(city.getId(), city.getName() + ", " + city.getState().getAbbreviation());
}
}
return SUCCESS;
}
public void setCity(String city) {
this.city = city;
}
public Map<String,String> getJson() {
return json;
}
}
----------------- Action(End) -----------------
In struts.xml file I given following entries
<action name="Autocomplete!*" class="gov.action.AutocompleteField" method="{1}">
<!-- <result type="json"><param name="root">json</param></result> -->
<result name="success" type="json" />
</action>
When I keep 'jsonplugin-0.34.jar' file getting below error
java.lang.NoClassDefFoundError: com/opensymphony/xwork2/util/TextUtils
After reading some posts, they said that we should not include this .jar in this new struts2.1.8 version. I removed this .jar file
I added 'struts2-dojo-plugin-2.1.8.1.jar' file in /WEB-INF/lib folder.
When I deploy the application getting below error
There is no result type defined for type 'json' mapped with name 'success'. Did you mean 'json'? - result
Can anyone please let me know, how to define 'json' in struts.xml file? in package level I even added 'json-default'
<package name="admin" extends="struts-default,json-default">
Thanks in advance.
Regards,
Sharath.

Posted by Martin Gainty <mg...@hotmail.com>.
supply the fully qualified action name to the url
<s:url var="url" value="/admin/Autocomplete!getNames.action"/>
also make sure there is a result defined for that action in your declarator
<action name="JSONList">
<result>/ajax/JSONList.js</result>
</action>
anyone seen result type='json' ??
as far "not getting there" you should follow dales advice d/l and install firefox
http://support.mozilla.com/en-US/kb/Firefox+exe+is+always+running
then install firebug plugin
http://getfirebug.com/downloads
you can view the entire DOM tree as well as interrogate request and resulting response
fill in the blank ..what name is at question mark

Hi Dale,
Can you please send me sample example using AJAX in struts 2.1.8, where action method returns json list to a page.
Thanks in advance.

Because your problem doesn't appear to be a server-side one, but rather
what's going on inside the browser.

If that's true, then your action configuration including the ! character
may or may not work as you intend, as dynamic method invocation
effectively does the same thing as your wildcarding there.

AJAX libraries run in the browser. Struts2 runs on the server. They're
really orthogonal. I'd advise picking a javascript library that you can
get your head around and learning to use it separately from struts, then
understanding the few small areas where requests sent/results parsed to
understand how that'll work with a struts-based server.
DOJO (at least the ancient version in the struts plugin) is dog slow in
the browser, so I'd avoid it if possible. My current project is based
on the prototype/scriptaculous libraries, but I've heard/seen good
things regarding jquery. Assuming that has components that do
asynchronous requests, I'd look at jquery.
http://www.zulutown.com/blog/2009/07/12/ajax-dynamic-content-with-struts2-jquery-and-json-plugin/
details one example of doing this with jquery directly.
If that's all too much for you to figure out, I believe there is an
effort at a jquery plugin (basically a sj taglib) that might be able to
help you. I had thought there was an effort to put that in the sandbox
or even support it as part of the normal struts distribution, but I
don't recall. It appears that this plugin resides at:
http://code.google.com/p/struts2-jquery/
not sure what relationship this one has to the former:
http://code.google.com/p/struts2-jquery-plugin/
All that said, if you just want to push forward with the deprecated dojo
plugin, I'll again suggest using firebug within firefox to track down
what's going wrong in the browser.

Hi Dale,
Tried all the changes which you mentioned like keeping only 'json-default' and removing 'json' from result type but facing same problem...
In struts.properties file having below line
struts.enable.DynamicMethodInvocation = true
I'm using 'struts2-dojo-plugin-2.1.8.1.jar' plugin for doing AJAX, and you mentioned that dojo is deprecated. Can you please tell me how to do AJAX in struts2.1.8?? what components(similar to dojo) we need to use to get AJAX functionality.
Thanks for your help.

json-default extends struts-default, so no reason do list both (and I don't even know if that works).
json-default defines the result type json, so no reason to redefine it again.

I don't know if action names can include "!". Do you have struts.enable.DynamicMethodInvocation set to false and you're trying to emulate that behavior here?

Sounds like you're having problems not with json but with dojo. Note, the dojo plugin is old and deprecated. I cannot help there. Javascript errors on your page might be preventing other javascript from running. For debugging js I'd suggest the firebug plugin to firefox.

Hi All,
Added below lines in struts.xml file
<package name="admin" extends="struts-default,json-default">
<result-types>
<result-type name="json" class="org.apache.struts2.json.JSONResult" />
</result-types>

<result type="json"><param name="root">json</param></result>
</action>
</package>
Added following lines .jsp file
<b>Search JSON: </b>
<s:url id="url" action="Autocomplete" method="getNames" />
<sx:autocompleter href="%{url}" loadOnTextChange="true" loadMinimumCount="3" />
even included <%@ taglib prefix="sx" uri="/struts-dojo-tags"%> and
<head>
<sx:head />
</head>
When it builds the page it is showing below lines
<input dojoType="struts:ComboBox" dataUrl="/admin/Autocomplete!getNames.action" id="manageForm_" keyName="nullKey" loadOnType="true" loadMinimum="3" visibleDownArrow="true" />
<script language="JavaScript" type="text/javascript">djConfig.searchIds.push("manageForm_");</script>
after entering 3 or more characters it supposed to invoke 'getNames' method but it is not even starting invocation of this method....
Can anyone please let me know where I'm wrong.
Thanks in advance.

Sharath.

Re: Using json in Struts 2.1.8.1
Posted by Denis Cabasson <de...@gmail.com>.
As of struts 2.1.8, you have (well can, but it's recommended) use the
struts2-json-plugin rather than the googlecode version (the google code
one has been transferred to apache as a struts 2 plugin).
To do that, just use the class name org.apache.struts2.json.JSONResult
(see
http://struts.apache.org/2.1.8.1/struts2-plugins/struts2-json-plugin/apidocs/org/apache/struts2/json/JSONResult.html
) for your json result.
Ie :
<package name="package_name" extends="struts-default" namespace="/namespace_name">
<result-types>
<result-type name="json" class="org.apache.struts2.json.JSONResult" />
</result-types>
And include the jar file (can be found at http://repo2.maven.org/maven2/org/apache/struts/struts2-json-plugin/2.1.8.1/struts2-json-plugin-2.1.8.1.jar or in the complete distribution of struts 2) in your classpath.
So your understanding is good, but you need the struts2-json-plugin-2.1.8.1.jar file too.

Re: Using json in Struts 2.1.8.1
Posted by sharath karnati <ka...@yahoo.com>.
Hi sameer,
In struts 2.1.8.1 having 'struts2-dojo-plugin-2.1.8.1.jar' file so we don't need to use 'jsonplugin-0.34.jar' for using json. This is my understanding :)
If we are not including 'jsonplugin-0.34.jar' then we cannot use "com.googlecode.jsonplugin.JSONResult"
With new Struts 2.1.8.1 version how to use json without using any annotations in action.
Can someone please send me some examples for using json in this new version of struts2.
Thanks in advance.
Regards,
Sharath.

Do something like this:
In your struts.xml define result types as follows:
<package name="package_name" extends="struts-default"
namespace="/namespace_name">
<result-types>
<result-type name="json" class="com.googlecode.jsonplugin.JSONResult" />
</result-types>
then in the action mapping:
<action name="action_name" class="AutocompleteField "
method="getCities()">
<result type="json">
</result>
</action>
and put annotation in the getter method in your action class:
@JSON
public Map<String,String> getJson() {
return json;
}
and u can use this json map in the jsp page.
I Hope it helps!

Hi All,
I'm having following Action
----------------- Action(Begin) -----------------
public class AutocompleteField extends ActionSupport {
private String city;
private Map<String,String> json;
public String execute() throws Exception() {
return SUCCESS;
}
public String getCities() throws Exception() {
json = new HashMap<String,String>();
if(city != null && city.length() > 0) {
CityDao dao = new CityDao();
List<City> cities = dao.getCitiesStartingWith(city);
for(City city : cities) {
json.put(city.getId(), city.getName() + ", " + city.getState().getAbbreviation());
}
}
return SUCCESS;
}
public void setCity(String city) {
this.city = city;
}
public Map<String,String> getJson() {
return json;
}
}
----------------- Action(End) -----------------
In struts.xml file I given following entries
<action name="Autocomplete!*" class="gov.action.AutocompleteField" method="{1}">
<!-- <result type="json"><param name="root">json</param></result> -->
<result name="success" type="json" />
</action>
When I keep 'jsonplugin-0.34.jar' file getting below error
java.lang.NoClassDefFoundError: com/opensymphony/xwork2/util/TextUtils
After reading some posts, they said that we should not include this .jar in this new struts2.1.8 version. I removed this .jar file
I added 'struts2-dojo-plugin-2.1.8.1.jar' file in /WEB-INF/lib folder.
When I deploy the application getting below error
There is no result type defined for type 'json' mapped with name 'success'. Did you mean 'json'? - result
Can anyone please let me know, how to define 'json' in struts.xml file? in package level I even added 'json-default'
<package name="admin" extends="struts-default,json-default">
Thanks in advance.
Regards,
Sharath.
