Java type cannot be resolved

I have a statement

String pass = com.liferay.portal.util.PortalUtil.getUserPassword(renderRequest);

that causes the following error in eclipse IDE:

The type javax.servlet.http.HttpSession cannot be resolved. It is indirectly referenced from required .class files

Why is this error occuring? I have added an import statement for the type but yet the error remains. How can I remove this error?

Thanks for your help.

In order to remove this error You need to add the Servlet API to your classpath. In Tomcat 6.0, this is in a JAR called servlet-api.jar in Tomcat's lib folder. You can either add a reference to that JAR to the project's classpath, or put a copy of the JAR in your Eclipse project and add it to the classpath from there.

If you want to leave the JAR in Tomcat's lib folder:

Right-click the project, click Properties. Choose Java Build Path. Click Add External JARs... Browse to find servlet-api.jar and select it. Click OK to update the build path.

if you copy the JAR into your project:

Right-click the project, click Properties. Choose Java Build Path. Click Add JARs... Find servlet-api.jar in your project and select it. Click OK to update the build path.

Download Apache-Tomcat. Browse to the lib folder. Now open eclipse and go to build-path-> configure build path-> add external libraries.

Check your project setup. If I recall correctly, this has to do with com.liferay.portal.util.PortalUtil.getUserPassword(renderRequest) using javax.servlet.http.HttpSession under the hood, but eclipse isn't able to find that class. Try adding the servlet api jar to the project class path

You need to put the definition of that class (usually contained in a servlet.jar file) into the build path of your project (right-click on the project, select "Properties" and then "Build Path").

It sounds like you haven't referenced the right libraries. Add a reference to servlet.jar.
