I want to add 3 button into struts form. My code is :
@Action("/admin/product/insert")
public String insert() throws Exception {
if(upload.hasFile()){
model.setImage(upload.getFileFileName());
upload.saveTo("../images/customers/");
}
else{
model.setImage("product.png");
}
XHibernate.save(model);
return "new";
}
@Action("/admin/product/update")
public String update() throws Exception {
if(upload.hasFile()){
model.setImage(upload.getFileFileName());
upload.saveTo("../images/customers/");
}
System.out.println("update");
XHibernate.update(model);
return "input";
}
@Action("/admin/product/delete")
public String delete() throws Exception {
XHibernate.delete(model);
return "new";
}
In jsp:
<s:form enctype="multipart/form-data" theme="simple" role="form">
<div class="form-group col-md-4">
<label for="id">Product Id</label>
<s:textfield id="productId" name="id" cssClass="form-control" />
</div>
<div class="form-group col-md-4">
<label for="name">Product Name</label>
<s:textfield name="name" cssClass="form-control" />
</div>
<div class="form-group col-md-4">
<label for="unitPrice">Unit Price</label>
<s:textfield name="unitPrice" cssClass="form-control" />
</div>
<div class="form-group col-md-4">
<label for="unitBrief">Unit Description</label>
<s:textfield name="unitBrief" cssClass="form-control" />
</div>
<div class="form-group col-md-4">
<label for="discount">Discount</label>
<s:textfield name="discount" cssClass="form-control" />
</div>
<div class="form-group col-md-4">
<label for="quantity">Quantity</label>
<s:textfield name="quantity" cssClass="form-control" />
</div>
<div class="form-group col-md-4">
<label for="productDate">Product Date</label>
<s:textfield name="productDate" cssClass="form-control" />
</div>
<div class="form-group col-md-4">
<label for="supplier.id">Supplier</label>
<s:select name="supplier.id" list="suppliers" listKey="id"
listValue="name" cssClass="form-control" />
</div>
<div class="form-group col-md-4">
<label for="category.id">Category</label>
<s:select name="category.id" list="categories" listKey="id"
listValue="name" cssClass="form-control" />
</div>
<div class="form-group col-md-4">
<label>Features</label>
<div>
<label><s:checkbox name="available" /> Available</label> <label><s:checkbox
name="special" /> Special</label> <label><s:checkbox
name="latest" /> latest</label>
</div>
</div>
<div class="form-group col-md-4">
<label for="image">Image</label> <input id="image" type="file"
name="upload.file">
<s:hidden name="image" />
</div>
<div class="form-group col-md-12">
<label for="description">Description</label>
<s:textarea id="index_description" name="description" rows="30"
cssClass="form-control" />
</div>
<div class="col-md-12">
<s:submit value="Thêm mới" action="admin/product/insert"
cssClass="btn btn-default" />
<s:submit value="Cập nhật" action="admin/product/update"
cssClass="btn btn-default" />
<s:submit value="Xóa" action="admin/product/delete" cssClass="btn btn-default" />
<a href="product/index" class="btn btn-default">Nhập lại</a>
</div>
</s:form>
The problem is it can't call the exactly action.
I always got the error: " There is no Action mapped for namespace /admin/product and action name admin/product/update.".
Do i have to split it to 3 forms ? OR Is there any way to have 3 buttons for 3 actions in 1 form like my code ? Any help would be great.
updated the logging when enable devmode:

To fix your current problem, you should add
<constant name="struts.enable.SlashesInActionNames" value="true"/>
in struts.xml, that is false by default, and will take all the part before the last slash as namespace instead of action name. BTW this has side effects:
If your action names have slashes in them (for example,
<action name="admin/home" class="tutorial.Admin"/>) you need to specifically allow slashes in your action names via a constant in the struts.xml file by specifying
<constant name="struts.enable.SlashesInActionNames" value="true"/>.See JIRA Issue WW-1383 for discussion as there are side effects to setting this property to true.
To fix the problem the right way, you need to make a correct usage of namespaces:
Action
@Namespace("/admin/product")
public class YourAction extends ActionSupport
@Action("insert")
public String insert() throws Exception {
/* .... */
}
@Action("update")
public String update() throws Exception {
/* .... */
}
@Action("delete")
public String delete() throws Exception {
/* .... */
}
JSP
<s:submit value="Thêm mới" action="insert" cssClass="btn btn-default" />
<s:submit value="Cập nhật" action="update" cssClass="btn btn-default" />
<s:submit value="Xóa" action="delete" cssClass="btn btn-default" />
You should also refactor the package structure for Actions and JSPs to follow the namespace structure.
P.S: remember to set action prefix enabled as explained in this answer if you are using a Struts2 version higher than 2.3.15.2:
<constant name="struts.mapper.action.prefix.enabled" value="true"/>
EDIT
If the namespace of the Action you are using to show your JSP is not the same of the actions called (in this case, /admin/product), you need to specify it in <s:form> tag:
<s:form namespace = "/admin/product"
enctype = "multipart/form-data"
theme = "simple"
role = "form">
And (if you are using a Struts2 version higher than 2.3.15.2), set the following property in struts.xml:
<constant name="struts.mapper.action.prefix.crossNamespaces" value="true"/>
because it has been disabled by default due to security reason.
