Eclipse & JSP: java.lang.NoSuchMethodError: javax.servlet.jsp.tagext.TagAttributeInfo.<init>(Ljava/lang/String;ZLjava/lang/String;ZZ)V

Question

I'm using Eclipse 3.4 with WTP 3.0.2 and running a fairly large Dynamic Web Project. I've set up the project so that I can access it at http://127.0.0.1:8080/share/ but whenever I do, I get the following error:

As none of the above files is my own, pointing out the cause of the problem is quite hard. Any ideas where to start looking?

Answer 1

I ended up answering my own question: the problem was that among the necessary JARs that I had added to Tomcat was a conflicting servlet.jar. When I removed this, the error disappeared.

Answer 2

Did you set a Tomcat path in "Preferences->Tomcat->Advanced->Tomcat base" ?

Try to clean that path (getting back to default configuration), and check if that does solve the problem.

Answer 3

most probably the tomcat plugin in the eclipse cause the conflict problem, i manage to solve the problem by getting the same version jar file and override it in the tomcat plugin in the eclipse.

Answer 4

I had similar problem and I had fixed this problem by Ensuring that i have correct version of servlet.jar in the classpath that is being taken by my application and also i had kept old J2EE.jar file in the classpath and that was causing the main problem. Hence I removed it from the classpath to ensure that it uses by default files.

Answer 5

I had the same problem running Eclipse Helios, with Maven handling dependencies and using Jetty as webserver. After updating to Spring 3.1 I suddenly got this problem, but only on my local development machine.

I first deleted the spring and jetty folders in my local maven repository and updated the dependencies, but that didn't improve the situation.

Then I just deleted the servlet-api and servlet-api-2.5 folders that comes with jetty (but leaving everything else), I got it to work.

All hail the magic of the classpath.
