I have two Set s set1 contains("A","B","C","D") elements set2 contains("E","F","D","G") elements I want to compare every element of set1 with every element of set2 and display matched elements using Struts2 tags. Try the code below: <s:iterator var="val1" value="set1"> <s:iterator var="val2" value="set2"> <s:if test="#val1 == #val2"> <s:property /><br> </s:if> </s:iterator> </s:iterator> Rearranged to better list the several ways: With two Iterator s: <s:iterator value="setOne" var="first" status="ctr1"> <s:iterator value="setTwo" var="second" status="ctr2"> <s:if test="%{#first == #second}">

I write the following code in JSP. <% String p_loginPassword = OpeCommon.LOGIN_PASSWORD; String p_encryptCode = OpeCommon.encriptPassword(OpeCommon.KEY_USER_ID, OpeCommon.KEY_USER_PASSCODE); %> <s:url id="printURL" action="actMod" method="printout"> <s:param name="<%=OpeCommon.LOGIN_PASSWORD %>"><%=OpeCommon.encriptPassword(OpeCommon.KEY_USER_ID, OpeCommon.KEY_USER_PASSCODE)%></s:param> </s:url> It displays error : According to TLD or attribute directive in tag file, attribute name does not accept any expressions How should I write for that, pls give me some suggestions. Don't use scriptlets

In struts2, I took advantage of built-in OGNL in struts2, naming my inputs like <input name='bag["item"].property'> Which went to getters/setters getBag().get("item").setProperty(value) I've upgraded to struts 2.2.1, and suddently those no longer work: the getter never gets called. The internet is utterly silent on using OGNL in parameters , as if nobody ever made complex forms. How do I get my map-parameters back? It turns out that they hardened restrictions on parameter names to boost security. So I had to add to my struts.xml: <interceptor-stack name="defaultStack"> <interceptor-ref name=

I would like to create an action class with no setter and getter on properties for the data coming from the user interface. Instead, I would like to use ServletActionContext.getRequest().getParameterMap() in my own builder class to construct the object. I had created my Action class with no properties. When I am submitting my form I am running into ognl.OgnlException: target is null for setProperty(null, "field-name", [Ljava.lang.String;@5513fab7) Is there any additional conventions or configurations required to convey Struts2 framework to not set properties and stop avoid the exception I am

Now I can get any desired results if I use the <s:if> tag in Struts2 <s:if test="status==1"> //do some stuff </s:if> but I don't know how to get the action currently executed, I am expecting like <s:if test="action==addaction"> //do some stuff </s:if> You can get action name from the context <s:if test="#context['struts.actionMapping'].name=='addaction'"> do some stuff </s:if> Since Struts version 2.3.34 and 2.5.13 #context is not available anymore because of security reasons (see WW-4852 ) As a workaround you can use #request which is documented here <s:if test="#request['struts.actionMapping
