I have one project in eclipse, and same exact project in netbeans (I sync / mirror).
I have several errors in eclipse like:
javax.servlet cannot be resolved to a type
Multiple annotations found at this line:
- javax.servlet cannot be resolved
to a type
And happening in this code segment:
<c:set var="surl" value="${pageContext.request.requestURL}" />
<c:choose>
<c:when test="${pageContext.request.queryString != null}">
<c:set var="squy" value="${pageContext.request.queryString}" />
</c:when>
<c:otherwise>
<c:set var="squy" value="t1=${t11}&page=${pageno}" />
</c:otherwise>
</c:choose>
<%--<c:set var="squy" value="${pageContext.request.queryString}" />--%>
<c:set var="sqm" value="?" />
<%--${surl}${sqm}${squy}--%>
<c:set var="surl2" value='${surl}${sqm}${squy}' />
<%--${surl2}--%>
<c:set var="sessvar" value="${surl2}" scope="session" />
But the project runs fine, no build errors, etc. I have in the lib folder:
jakarta.activation-2.0.0.jar
jakarta.el-api-4.0.0.jar
jakarta.servlet.jsp.jstl-2.0.0.jar
jakarta.servlet.jsp.jstl-api-2.0.0.jar
jakarta.servlet-api-5.0.0-M1.jar
jakarta.xml.bind-api-3.0.0.jar
Am I missing some? If so I have no idea where to get them.
And in the pom I have:
<dependency>
<groupId>org.glassfish.web</groupId>
<artifactId>jakarta.servlet.jsp.jstl</artifactId>
<version>2.0.0</version>
</dependency>
That came from a stackoverflow post. I am using tomee however. Is there something I need that I am unaware of. And this is a jakarta ee 9 project.
Using the following: io.github.hantsy maven-archetype-jakartaee9
All runs and builds are fine. Any help appreciated.
Also those jstl's I included I got from a github page, I cannot find any instructions on downloading jstl libraries from any jakarta site that's needed with examples.
To add please see this issue:
https://github.com/eclipse-ee4j/jstl-api/issues/54
I am in the same situation, I am having to hunt for what I can find using Google. I cannot find any tutorials or examples of how to install the jstl tags or what jars I need or even where they go.
Project works, but I'd still like to setup fully correctly.

Nitin DahyabhaiFriend Thanks for answering. Eclipse Version: 2021-06 (4.20.0). A jakarta ee 9 project. I even took all references out of pom to jstl. I downloaded
jakarta.servlet.jsp.jstl-2.0.0.jar from https://jakarta.ee/specifications/tags/2.0/ placed it in WEB-INF\lib. I even changed preferences to ignore these jstl errors,
but they still show up.
However the project builds fine and runs in server Tomee (apache-tomee-webprofile-9.0.0-M7) perfect. No errors running the project on server.
I think Eclipse must have a bug with jslt. I have this also in the jsp file:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
No errors show up in bean classes or servlets. Just those on the jsp jstl..
That's why I asked am I missing a jar, or is it a bug in eclipse. Netbeans shows no errors. I even made a war, deployed to Tomee, ran perfect.
