This seems to come up quite a bit. We had Hadoop as a dependency and had to do multiple exclusions. Some of these are probably redundant, but this finally worked. I should note that there was no change until I started excluding Jasper at the bottom.

<exclusions>
    <exclusion>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jsp-2.1</artifactId>
    </exclusion>
    <exclusion>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jsp-api-2.1</artifactId>
    </exclusion>
    <exclusion>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jsp-api</artifactId>
    </exclusion>
    <exclusion>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>servlet-api</artifactId>
    </exclusion>
    <exclusion>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>servlet-api-2.5</artifactId>
    </exclusion>
    <exclusion>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jetty</artifactId>
    </exclusion>
    <exclusion>

        <artifactId>jetty-util</artifactId>

    <exclusion>

        <artifactId>jasper-compiler</artifactId>

    <exclusion>

</exclusions>

Answer 2

Looks like you may have some versioning problem, maybe a conflicting jar file of some sort. Look here, maybe it'll help. You need to supply some more info about your runtime environment if you can't solve it.

Answer 3

Tomcat 5.5 does not support Servlet API 2.5 which is used by JSTL 1.2.

Upgrade to Tomcat 6.0 or downgrade the Servlet / JSP / JSTL versions.
