just tried deploy , run code on own computer , worked well. make sure project structure valid, included loginservlet.java file project right , loginservlet.class file @ right directory after compilation. project stucture:
make sure class @ web-inf/classes
if can't solve problem, should show project structure after compilation. maybe can you, if screenshot not you. don't forget i'm using maven build project. structure may bit different.
if using maven add following lines dependencies block of pom.xml file:
`
<dependency> <groupid>javax.servlet</groupid> <artifactid>javax.servlet-api</artifactid> <version>4.0.0</version> <scope>provided</scope> </dependency> `
if not, try add following line before class declaration block:
@webservlet(name="any name want", urlpatterns="/login")
