java - Struts2 s:url for a image in s:submit not working -

-

i have jsp form:

<s:form action="gestionpagos.action">     <s:hidden key="actividad.id" />     <s:submit type="image"          src="<s:url value ="/internal resources/imagenes/alta.png"/>">     </s:submit> </s:form>

but, when try render in browser, struts throws error:

org.apache.jasper.jasperexception: /private/gestioncalendarios/menucalendario.jsp (línea: 144, columna: 1) /private/gestioncalendarios/listadoactividadcolaboradores.jsp (línea: 51, columna: 64) tag <s:submit not ended

i'm pretty sure tag worked before, after update, didn't work anymore.

i can make work using classic html input tag, or splitting button 2 steps: using url tag variable , then, using in src field of submit. want know why isn't working , correct form of tag.

you can't use struts tags inside tag attribute. don't need provide action extension action attribute of s:form tag. rewrite like

<s:url var="imgurl" value ="/internal resources/imagenes/alta.png"/> <s:form action="gestionpagos">     <s:hidden name="actividad.id" />     <s:submit type="image" src="%{#imgurl}"/> </s:form>

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
