How to create Struts Drop down List? -

I am new to struts

I want to add drop down to the web page. That drop down should have four values The default and the first value will be (select).

I want to continue the selected value, when that form is opened again and when submitting, if the user does not choose any value from the drop down (meaning that the default value is present) I Do not allow the user to submit a warning unless the user selects an option from the dropdown.

An action. Java, Form.Java, Javascript file and jsp file. In action. Java, I agree to use ArrayList to keep separate drop down values. How can this be done please help me

  & lt; S: select list = "# {'': 'Select', 'key1': 'value1', 'key2': 'value2'}" key = "selectedValue" & gt; & Lt; / S: Select & gt;    Or do you have a list object (id, value)  
  & lt; S: select key = "selectedValue" list = "yourlists" headerKey = "" header value = "list" list = "id" list value = "value" />

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!

Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
