Question

IntelliJ 9 unable to recognize Implicit Object methods in JSPs?

Answer 1

+2 A:

You'll have this problem with out, pageContext and jspContext because they use classes provided with the JSP api (not the servlet API).

To use them (if you're working with a maven project) add this dependency :

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jsp-api</artifactId>
    <version>2.0</version>
</dependency>

If you have the problem with every implicit object (session, request, etc.) you should add the servlet api dependency too :

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
</dependency>

Thanks for the response, Colin. I'm actually not working with a Maven project. This is just plain old IntelliJ IDEA deploying an exploded war artifact to Tomcat 7. I'm open to using a Maven project as an alternative, but it seems odd that I'd need to just to clean up all the red in the editor...

Did you add the application server libs in your project ? In `file` -> `Project structure` -> `Modules` -> `Dependencies` -> `Add`. If you configured tomcat as an application server in IntelliJ you'll be able to add the dependencies.

Eureka! Okay, so gotta add the app server libraries to the project dependencies. I didn't realize that these objects were web app specific. So, if I'm deploying to a different app server at some point (JBoss, for instance), I'd have to do the same thing with its libraries? Thanks so much for your help, Colin.

You don't really have to do that. This allow to use libs provided by your app server, if you only use servlets and JSP, you won't need to add other deps. But if you want for example use EJB etc. you'll have to add JBoss libs. Anyway, you should have a look at Maven, it will simplify this task for you by using only the dependencies you've defined yourself.

Will do. Thanks again!
