I'm trying to set parameter value bulkID from form in ftl file to action class, but unable to set. Following is the code:
struts.xml file
<action name="bulk" class="com.action.BulkChangeMainAction">
<result name="input" type="freemarker">/resources/templates/bulk-changes.ftl</result>
</action>
BulkChangeMainAction.java
public class BulkChangeMainAction {
private int bulkID;
public int getBulkID() {
return bulkID;
}
public void setBulkID(int bulkID) {
this.bulkID = bulkID;
}
public String input() {
return INPUT;
}
}
bulk-changes.ftl
<form id='filter-form' action="<#s.url action='bulk' method='input'/>" method="post" name="filterForm">
<input type="text" id="bulkID" name="bulkID"/>
<input type="submit" value="Go"/>
</form>
Try using the struts2 form tag and sth like the following (I assume input is the action you want to call?):
<s:form action="bulk.input.action" method="post">
<s:textfield name="bulkId" label="Bulk Id" />
<s:submit value="Confirm" />
</s:form>
Here is a nice complete example too:
http://www.codejava.net/frameworks/struts/handling-form-data-in-struts2
if you need to keep the current format you have, please try changing int to String or Integer and see if it works.

Im using displaytable with tiles. Problem is in my crud application, when I search something its loading data into display table,
and when I click on 2nd page its load data to 2nd page as I give requestURI="searchorgs". All works fine upto that,
Then I call Edit template and after submitting edited data it should load data to table. Its also work fine but when I click 2nd page
Its goes to search page as I mention in requestURI="searchorgs". I need to keep in same page with out moving to search page. Same table is insert in to add,edit,search jsp pages in tiles.xml. I dont want to define 3 separate tables for this.
Application I struts2 tiles integration one.
action class search method :
public String search() {
organisationSearch = new OrganisationSearch();
organisationSearch.setAoName(aoName);
orglist = orgBo.searchOrg(organisationSearch);
return "search";
}
Struts xml :
<action name="*orgs" class="com.ast.action.admin.OraganisationAction"
method="{1}">
<result name="add" type="tiles">orgAddTemplate</result>
<result name="search" type="tiles">orgTemplate</result>
<result name="delete" type="tiles">orgTemplate</result>
<result name="edit" type="tiles">orgEditTemplate</result>
<r
</action>
table :
<s:form theme="simple" id="delete" action="deleteorgs">
<display:table id="studentTable" name="orglist" pagesize="5" cellpadding="5px;" id="row" cellspacing="5px;"
style="margin-left:50px;margin-top:20px;" requestURI="searchorgs">
<display:column style="width:5px;">
<s:checkbox name="chkBox" id="check%{#attr.row_rowNum - 1}" value="%{#attr.row.chkBox}" fieldValue="%{#attr.row.aoId}" />
</display:column>
<display:column title="Action" style="width:10px;" value="Edit" href="vieweditorgs" paramId="aoId" paramProperty="aoId" />
<display:column title="View" style="width:10px;" value="View" href="vieworgs" paramId="aoId" paramProperty="aoId" />
<display:column title="Dlt" style="width:10px;" value="Dlt" href="singledeleteorgs" paramId="aoId" paramProperty="aoId" />
<display:column property="aoId" title="ID" />
<display:column property="aoName" title="Name" />
</display:table>
You need to define action in requesturi programmatically.
Please see this
dispalay tag table pass value to requestURI
In action class
private String myActionName;
public String search() {
organisationSearch = new OrganisationSearch();
organisationSearch.setAoName(aoName);
orglist = orgBo.searchOrg(organisationSearch);
//set action name
myActionName="action1.action";
return "search";
}
//other methods
public void setMyActionName(String myActionName) {
this.myActionName = myActionName;
}
public String getMyActionName() {
return myActionName;
}
In jsp file
<display:table id="u" name="userlist" pagesize="10" requestURI="${myActionName}" >
...
</display:table>
If I misunderstood your question, Please let me know.
I created a jsp page which has a form , I am trying to populate the data members of the action classfrom this form, after submitting the form the control is being moved to the action class but the action class data members are not populated.
my jsp page looks like this.
<s:actionerror />
<s:form action = "retrieve" method="post">
<s:textfield name = "form1" value = "form1" />
<s:textfield name="cid"/>
<s:submit type = "submit" name = "sub" value="submit"/>
</s:form>
my action class looks like this.
public class CustomerUpdate extends ActionSupport {
private String form1 ;
private String cid ;
public String execute() {
System.out.println(form1) ;
System.out.println(cid) ;
}
Here after submission of form I expect form1 variable in action class should have the value as "form1" but it is still null.
can anyone help where am I going wrong?
Thanks in advance.....
I am not sure if you have configuration file that maps action class to your jsp file.
normally configuration file is an xml file in your src folder. example:
<struts>
<package name="default" extends="struts-default">
<action name="retrieve" class="CustomerUpdate">
<result>/xxx.jsp</result>
</action>
</package>
</struts>
Since your execute method is of return type string, return some string. Based on string returned from execute method you can redirect. otherwise change it to void.
If you already have properly configured action class with your jsp, then for using member variables, code in jsp might look like:
<form action = "retrieve" method="post">
<s:textfield name = "form1" value = "${form1}" />
<s:textfield name="${cid}"/>
<s:submit type = "submit" name = "sub" value="submit"/>
</form>
and also since member variable are private:
system.out.println(getForm1);
system.out.println(getCid);
Hope that helps
At first place, your code will not compile.
As i assume that struts.xml file contains below lines,
<action name="retrieve" class="CustomerUpdate" method="execute">
<result name="success">/success.jsp</result>
</action>
Update the CustomerUpdate as below and check the program.
public class CustomerUpdate extends ActionSupport {
private String form1 ;
private String cid ;
public String execute() {
System.out.println(form1) ;
System.out.println(cid) ;
return "success";
}
//getter & setter for form1 & cid
}
please try out the above code sample and i think it will work.
In struts2 actions the injection is used for setting the property values of an action class, so the properties are updated by form fields on the form submission. To discover which form is submitted I create a method calling isFormSubmitted() and in there I check a redundant property created only for this motive. The property is updated in a hidden field. But I find this workout so dirty! I think that there must be a better way to solve this problem.
What I do is:
<s:form name="form1">
<s:hidden name="submit" value="10" />
...other fields go here
</s:form>
in the action class I have getSubmit, setSubmit methods and the following method:
public boolean isFormSubmitted(){
return (submit == 10);
}
Your can call different action methods in your action, not only "execute" method. Just put the parameter with the name like "method:actionMethodName" in your request. Here is example:
public class MyAction extends ActionSupport {
public String execute() {
// Base code
return SUCCESS;
}
public String one() {
// Code one
return SUCCESS;
}
public String two() {
// Code two
return SUCCESS;
}
}
And here is jsp:
<s:form action="MyAction">
<input type="submit" value="Call execute"/>
<input type="submit" name="method:one" value="Call method one"/>
<input type="submit" name="method:two" value="Call method two"/>
</s:>
Or you can do it like this:
<s:form action="MyAction" name="form0">
<!-- call execute-->
</s:>
<s:form action="MyAction" name="form1">
<!-- call method one-->
<input type="hidden" name="method:one"/>
</s:>
<s:form action="MyAction" name="form2">
<!-- call method two-->
<input type="hidden" name="method:two"/>
</s:>
You should use <s:form> tag action attribute to submit to specific action.
<s:form action="action1">
...
</s:form>
<s:form action="action2">
...
</s:form>
See the <s:form> tag documentation: http://struts.apache.org/2.x/docs/form.html.
Update
Then just use separate actions for loading and saving the user.
you should do the submission of the form something like this.
<s:form name="form1">
<s:hidden name="submit" value="10" />
</s:form>
create a java script function
function onclick()
{
document.form1.submit();
}
then create getters & setters in action for hidden field
and in execute method
public String execute()
{
setSubmit(10);
return SUCCESS;
}
Update :
or
<s:a href="your_action"></a>

Some one could help me please ?
I have this problem since yersterday.
Prepare interceptor calls prepare() on actions which implement
Preparable. This interceptor is very useful for any situation where
you need to ensure some logic runs before the actual execute method
runs.
Your action should extend Preparable interceptor and override prepare() method, give the pre populated data.
Struts2 Prepare Interceptor
Put AnneesResultatsList in session
Map session=ActionContext.getScession();session.put("list",AnneesResultatsList );
<pre>
s:select name="anneeResultat" label="Année de résultats" list="%{#session.list}""></s:select>
</pre>
actually it is,
Map session = ActionContext.getcontext().getsession();
session.put("key",list);
<s:select list="%{#session.key}">
I am doing fileupload process in Struts2 application. When i display filename and contenttype in action class it showing null pointer exception.
I have included jar files and using the following codes.

UPLOADFILECONTENT TYPE:null
UPLOADFILENAME:null
UPLOADFILE:null
So anybody please help me to get the filename,filepath in uploading process of Struts2.
Hi Shiva the problem is with the tag you are using in action class.
<s:file name="upload" label="File" size="40" />
where upload property is not existing in your action class there is a property File file you use file instead of upload so that will solve your problem
<s:file id="file" name="file" />
