ArrayList<Integer> list = new ArrayList<Integer>();
list.add(2012);
list.add(2013);
list.add(2014);
list.add(2015);
can we do same as above using struts2 tags. may be by using
<s:set name="myList" value={somedynamic values} />
actually I want to create a list of number of 10 years on JSP page using Struts2 tags.
Regarding to your question answer is yes,but that is not an good idea to create number of 10 years in jsp page.
However, this is using arrylist in dynamic way
<s:select label="Years" headerKey="-1" headerValue="Select Years" list="list" name="your desire name" />
in the place of list property you have to give arrayList variable in your case it is list
means,
<s:select ---- list="your array list variable" --------- />
and you have to define this action name in struts.xml
eg:
<action name="yourarrylistvariable" class="your class" method="your method">
<result name="success">your jsp page</result>
</action>
This is using arrylist in static way here you have to change the list value
<s:select label="Years" headerKey="-1" headerValue="Select Years"
list="#{'2000':'2000', '2013':'2013',.....}" name="your desire name" />
For More Info You can refer this link struts2 select
Sure you can, thanks to the OGNL you can create lists like so:
<s:set var="myList" value="{2012,2013,2014,2015}" />

I use DisplayTag in my struts2 application and i want to hit query on clicking pagination.
Ex : When user click on the next page or any page then query is fire on action class.
FILE : displayTag.jsp
<display:table name="list1" sort="list" size="20" pagesize="5" id="table1" export="true" requestURI="" partialList="true">
<display:column property="no" group="1" sortable="true" headerClass="sortable"></display:column>
<display:column property="nam" group="2" sortable="true" headerClass="sortable"></display:column>
<display:column property="ct" group="3" sortable="true" headerClass="sortable" autolink="true"></display:column>
<display:setProperty name="export.excel.filename" value="diplayTag.xls"></display:setProperty>
<display:setProperty name="export.pdf.filename" value="diplayTag.pdf"></display:setProperty>
<display:setProperty name="export.csv.filename" value="diplayTag.csv"></display:setProperty>
<display:setProperty name="export.pdf" value="true"></display:setProperty>
</display:table>
I use request.setAttribute("list1", li); where i set all data in list1(ArrayList) and pass to the displayTag.jsp.
DisplayTag get all data and display in the table format. But my need is to pass only 5 data at a time and on clicking next page action class send other 5 data and so on.
I refer link : Display tag pagination problem
But i can not understand because i'm use MySql and also new on DisaplyTag.
DB : MySql
Framework : struts2
After researching and hard working i found answer.
FILE : displayTag.jsp
<display:table name="list1" sort="external" size="20" pagesize="5" id="table1" export="true" requestURI="disTag" partialList="true">
// code as above
</dispaly:table>
here requestURI="disTag" is a action name.
FILE : struts.xml
<action name="disTag" class="className">
<result name="success">/displayTag.jsp</result>
<result name="error">/error.jsp</result>
</action>
FILE : class file
page = Integer.parseInt(request.getParameter((new ParamEncoder("table1").encodeParameterName(TableTagParameters.PARAMETER_PAGE))));
if(page != 0)
{
start = (page - 1) * 5; //5 is row or data per page.
}
getData(start, 5); //getData is a method which store all data in ArrayList. Based on start index.
i want to output some data within jsp using json format. i am trying to use json-taglib for same. Can someone please help me with combining jsontaglib with atg dsp tags? below is the code.
<%# taglib prefix="json" uri="http://www.atg.com/taglibs/json" %>
<dsp:page>
<json:property name="image" value="<dsp:valueof param='mysite.image'/>" />
<json:property name="name" value='<dsp:valueof param="mysite.name"/>' />
</json:object>`
</dsp:page>
But the code above is just printing my dsp:valueof tags instead of it's value. Why?
Also, i need to use foreach droplet to print out a nested json array.Can someone help me with an example on how can i achieve that?
TIA
Since you are explicitly importing the json taglib, you might need to import the dsp taglib too?
Apart from that you are missing a starting tag for your <json:object>, the rest appears to be correct.
An example of using the ForEach droplet to generate a nested json array is as follow:
<dsp:importbean bean="/atg/dynamo/droplet/ForEach" />
<dsp:page>
<json:object>
<json:property name="image">
<dsp:valueof param="mysite.image" />
</json:property>
<json:property name="name">
<dsp:valueof param="mysite.name" />
</json:property>
<json:array>
<dsp:droplet name="/atg/dynamo/droplet/ForEach">
<dsp:param name="array" param="SomeParameterPassedToThisDroplet" />
<dsp:oparam name="output">
<json:object>
<json:property name="element.propertyname">
<dsp:valueof param="element.propertyvalue" />
</json:property>
</json:object>
</dsp:oparam>
</dsp:droplet>
</json:array>
</json:object>
</dsp:page>
I am new to thymeleaf and am converting all my jsp code to thymeleaf.I don't know how to convert this below code to thymeleaf.Do anyone know how to convert the below code to thymeleaf?
<logic:iterate id="id" property="idList" name="sampleForm" indexId="i">
<label for="id<%=i%>">
<bean:write name="id" property="id" />
</label>
</logic:iterate>
Please tell me how to initialize the index value in thymeleaf to be used in some values??
<label th:each="id,status : ${idList}" th:for="|id${status.index}|" th:text="${id.id}"></label>
th:each will iterate over the idList, assign each item to id and create a label for each item. The status of the item can be assigned by adding an extra name, separated by a comma (status in this example).
th:for will set the for attribute of the label. The pipes (|) are used for easy string concatenation.
th:text will set the inner text of the label to the ID.
You can also use it like this:
<label th:each="id : ${idList}" th:for="${'id' + idStat.index}" th:text="{id.id}">
This starts the index from 0
If you want to start the index from 1 use this
<label th:each="id : ${idList}" th:for="${'id' + idStat.count}" th:text="{id.id}">
Check out the Thymeleaf documentation
Here is my code:
<html:text name="rptData" property="emailAddress" onblur="checkIfEmpty('<bean:write name="rptData" property="status" />' , this.id)" />
This is nested inside a logic:iterate tag. What i need to do, is to pass value of 'status' to the javascript checkIfEmpty method. But i guess there is some error in the quotes. It is not working properly. Please anyone guide me. Thanks.
You can't nest custom tags like that, period, and it's unfortunate most of the answers imply you can, because that represents a fundamental misunderstanding of JSP.
Ideally, you wouldn't use the <logic:iterate> tag, as its use is not recommended when you have JSTL available: when JSTL and Struts 1 tag functionality overlaps, use the JSTL option. Then use standard JSP EL to access the variable.
<c:forEach items="listOfThings" var="current">
...
<html:text ... onblur="checkIfEmpty('${rptData.status}', ${current.id})" ...
...
In this example I also assumed that this was supposed to refer to the current iteration object, defined in the <c:forEach> tag.
ok after doing some research i found out the answer.
if i have some code like this:
<html:text styleId="emailAddress+<%=statusC.toString() %>" name="rptData" property="emailAddress" />
its output is as follows:
<input type="text" name="emailAddress" value="abc#gmail.com" id="emailAddress+<%=statusC.toString() %>" />
but if i use
<html:text styleId="<%=statusC.toString() %>" name="rptData" property="emailAddress" />
the output is:
<input type="text" name="emailAddress" value="abc#gmail.com" id="Approved" />
That means without string concatenation the output is correct. i.e. only using
styleId="<%=statusC.toString() %>"
rather then
styleId="emailAddress + <%=statusC.toString() %>"
or even
styleId="emailAddress" + <%=statusC.toString() %> - This results in an error, though
yeilds correct output.
So the workaround is to first intialize a complete java String in a scriplet then use it inside the styleId tag.
<% String emailId = "emailAddress" + statusC.toString() ;%>
<html:text styleId="<%=emailId%>" name="rptData" property="newEmailAddress" />
It will work fine. Cheers !
You might want to try adding some escape characters while using double quotes inside double quotes like in your case it would be some like:
onblur="checkIfEmpty('<bean:write name=\"rptData\" property=\"status\" />' , this.id)"
Try this:
<html:text name="rptData" property="emailAddress" onblur="checkIfEmpty('<bean:write name=\'rptData\' property=\'status\' />' , this.id)" />
How to write dynamic struts <html:option>, I'm doing as below
<logic:iterate id="data" name="sendEmailForm" property="eventList">
<html:option value="<bean:write name="data" property="eventId"/>"/>
<bean:write name="data" property="title"/>
</html:option>
</logic:iterate>
but getting following error:
JSPG0069E: Unmatched end tag found while parsing jsp. Expecting
logic:iterate found html:option at [87,130]
is there another way to do so?
Thanks in advance.
<html:option property="title">
<html:optionsCollection name="sendEmailForm" label="title" value="eventId" />
<html:option>
html:option tag
property="?" whatever you want to set like if attribute is title and corresponding method (getTitle(), setTitle(String title) ) then property= "title"
html:optionsCollection tag
name = "?" whatever you have put in your request/session attribute
like (request Or session).setAttribute("sendEmailForm", ListArr);
then name="sendEamilForm"
listArr is array of object of bean ( may be formbean or simple pojofile/bean).
label ="?" what ever you want to show like if you have attribute 'title' and
corresponding setter(setTitle(String title)) and getter(getTitle()) method then
label="title"
value ="?" what ever you want to put as value in option. you call your getter method
corresponding attribute like if you have attribute eventId and method (
setEventId(String eventId) , getEventId() ) then value="eventId"
ok finally i found below for solution
<html:optionsCollection name="sendEmailForm" property="eventList" label="title" value="eventId" />
