I'm having trouble importing the org.apache.commons.lang.StringEscapeUtils which gives me the error: The import org.apache.commons.lang cannot be resolved I know this question has been posted a number of times but i tried them and it didnt solve my problem.
Things i did were:
Download the packages and add them to the WEB-INF/lib folder
Imported but it still showed me the error
Restarted server
Cleaned project several times
Closed eclipse and back on
Nothing solved my problem. Any suggestion?
You are using version 3 of Apache Commons Lang. The correct import is:
org.apache.commons.lang3.StringEscapeUtils
Note the lang3 part of the path

I'm working on a Java web application in Apache NetBeans. Everything is working well, but a warning message appears at the package level (first line):
Missing mandatory Classpath entries. Resolve Project Problems.
Here is a screenshot of that problem in the IDE:
The yellow bulb offers me the possibility to solve the problem, but it doesn't work.
Did you see any kind of alert? Like this, or maybe at the bottom, when you first load the project Error Missing Mandatory ClassPath? If this is your case, try clicking on the message.Netbeans need to donwload some extra files. I had the same problem and it worked for me
I added a library with several packages one of which is "no.stelar7.api.r4j.impl.lor". When I go to import this package to use it in my code I am given an error saying it can't be resolved, I have tried deleting the library and re-importing it with no luck and need any help. There is another package in the library called "no.stelar7.api.r4j.impl", is it possible this is causing me errors?
Check if the library available for your current java version
I'am new on Jena.
I followed the starting tutorial here: https://jena.apache.org/tutorials/rdf_api.html
However, I get error on eclipse. Eclipse can't resolve the import of "StmIterator".
The type org.apache.jena.rdf.model.StmtIterator cannot be resolved.
It is indirectly referenced from required .class files.
Although the build path seems to be correct.
I'm working with Jena 3.8.
Thank you for your help
Solution:
The problem has been solved by migrating from Eclipse Indigo (that I used at the beginning) to Eclipse Juno.
I'm trying to import this library in order to use the RandomStringUtils class, but always I'm getting the error in the title of the question.
This is an ANT project, so I downloaded the library from Apache (http://commons.apache.org/proper/commons-lang/download_lang.cgi) and put it in the lib folder of the project. However, it's not working.
I got another library in this folder (org.apache.commons.cli) and it's working fine.
edit: ok, this is solved... It's a bug in Eclipse saying the import cannot be resolved.

Though I have all my source in proper packages.It couldn't find at the time of Building Project.Normally it shows links everything.But at the time of Build Project or Autobuild while directly running project.
The import ecnet.rd.config cannot be resolved
like it shows for all the internal imports.But external imports like imports from JAR files are working.
P.S :
My Eclipse latestly crashed but it was working well after that, Once again this kind of things are happening.
Please help to find the way to solve this.
In my experience, it is usual with Eclipse to have the build messed up. Make sure Build automatically is checked and Clean. If it doesn't work, restart Eclipse and do again.
Also as Tech Junkie comments below, try also Clean all projects.
I've seen this happen and another approach to take which is similar to m0skit0 solution (if you are using Eclipse) is to right click on the project, select maven, select update project, make sure clean projects and refresh workspace are checked, and hit ok.
After hours of struggle, creating a new Eclipse workspace, reimporting the projects and resetting up the same tomcat instance worked.
Probably the eclipse settings got messed up, and the deploy wasn't being done correctly anymore.
