I also use this    lt    taglib prefix  c  uri  http   java sun com jsp jstl core    gt    but I don t get any error   Did you include the jstl jar in your library  If not maybe this causing the problem  And also the  tld  folder do you have it  And how about your web xml did you map it   Have a look on the info about jstl for other information

It will work perfectly when you will place the two required jar files under  WEB-INF lib folder i e   jstl-1 2 jar and javax servlet jsp under  WEB-INF lib folder   Hope it helps

This should work        lt    taglib uri  http   java sun com jsp jstl core  prefix  c    gt    and moreover please let us know why are you importing all these class   lt    page import  com library controller     gt    lt    page import  com library dao      gt    lt    page import  java util      gt    lt    page import  java lang      gt    lt    page import  java util Date    gt    We don t need to include java lang as it is the default package

I know this thread is a year old now but having experienced the same problem I managed to solve the problem by setting a target server for my project   i e  right-click on your project and select  Properties  -   Targeted Runtimes  and select the server you going to run your web app on  Tomcat 6 or 7

I added jstl jar in a library and added it to build path and deployment assembly but it dint worked  then i simply copied my jstl jar into lib folder inside webcontent  it worked  in eclipse lib folder in included to deployment assembly by default

I will throw one more solution into the mix  I downloaded a sample app and it was crimping only on this taglib  Turns out it didn t care for the single quotes around the attributes    lt    taglib prefix  c  uri  http   java sun com jsp jstl core    gt    Once I changed those and made sure jstl jar was in the web app  i was good to go

It has nothing to do about  lt    taglib uri  http   java sun com jsp jstl core  prefix  c    gt    Just go to project and right click then  project menu -  Clean the project error will definitely remove and update maven

User · Answer

Add both javax servlet jsp jstl-api-1 2 1 jar and standard-1 1 2 jar

After a couple of hit and trial I use this  This works for me    lt    taglib uri  http   java sun com jstl core  prefix  c    gt    WARNING  As BalusC correctly mentioned  this works for JSTL 1 0

User · Answer

I solved this issue  use below taglib    lt    taglib prefix  c  uri  http   java sun com jsp jstl core    gt    and add jstl-1 2 jar

User · Answer

As  ace mentioned you will need the jstl jar in your project  so if you are using maven  you could add this dependency    lt dependency gt       lt groupId gt jstl lt  groupId gt       lt artifactId gt jstl lt  artifactId gt       lt version gt 1 2 lt  version gt   lt  dependency gt    Source  http   mvnrepository com artifact jstl jstl   Hope it helps   EDIT  Most of servers already have this dependency  if you add it using maven it may cause version conflicts  like Method ClassNotFoundException  if you don t configure the server well  so it s better set a target server for your project  as  willix mentioned

User · Answer

You are probably targeting a server without built-in JSTL support  e g  some version of Tomcat   You will need to provision your own JSTL tag library

I tried  validating  de   jsp and   xml files in eclipse with the validate tool    right click on directory file - - validate  and it worked   Using eclipse juno   Hope it helps

User · Answer

You have to write as   lt   taglib uri  http   java sun com jstl core  prefix  c   gt    Make sure you have  jstl-1 0  amp  standard jar BOTH files are placed in a classpath

User · Answer

Try to add like this    lt   taglib uri  http   java sun com jstl core  prefix  c   gt    instead of having    lt   taglib uri  http   java sun com jsp jstl core  prefix  c   gt
