In my program, I am trying to import below classes but there comes a compile time error for this. Am I missing any jar there ? If yes, then which jar I am missing. Please help me.
"import net.java.util.TagValue;"
I am writing this in eclipse
A simple search on the net shows that net.java.util.TagValue class belongs to fixparser library. Make sure that this library is in your classpath when working on your project.

So, i am running a java project which have many library that are available in the current working directory but VS code seems to not recognize these library and giving out error "The import ###### cannot be resolved" ex: The import org.apache.pdfbox.pdmodel.PDDocument cannot be resolved"
here is the image that might help you to know more about it
This is the package that i am working on :
Here the org/apache is the library contain the class file that are need to be imported and FileArrangement.java is the file having the import statements
Error i have been receiving
this is what VS code is been showing
i really need your help because i really don't have any idea how to correct this
I have checked other projects and they are also showing the same result although the import statements for java classes like . java.util.ArrayList doesn't show any kind of error and i have tried to clean java in VS code it also didn't work
i just need to correct this error of VS code to import the classes that i need
No error on java.util package
Putting the libraries in your current working directory does not work for Java, you need to add them to the classpath.
If you're using maven, that manages the classpath for you.
If not, you can manage it in VS Code by executing the Java: Configure Classpath command from the Command Palette (Ctrl+Shift+P).
You can add dependencies via Referenced libraries under the JAVA PROJECTS panel.
Or use java.project.referencedLibraries setting in settings.json.
For example:
"java.project.referencedLibraries": [
"library/**/*.jar",
"/home/username/lib/foo.jar"
]
Details can be found in configure-classpath and manage-dependencies.
I'm a n00b coder. I found an interesting library and trying to start toying with it. Which is not going great. This library is from 99' and uses JUnit (which I'm unfamiliar with) so there is a lot of confusing stuff. But it seems like the source of my failing even more elementary. Namely I have troubles importing packages.
This library has a test called StandardEvalTest.java. I moved to it to main Java directory and now I'm trying and failing to launch it using JUnit.
This package path org.pokersource.game.Deck goes directly from the directory where the test StandardEvalTest.java sits.
I also added the main java directory to the PATH environmental variable. Which as I assumed will allow import to locate the package.
None of those two things help. Also I was suspecting that maybe Deck.java and Deck.class are not enough and I have to do some work to create a package from it. But as far as I can say from Oracle doc the only thing needed is a package name in the header. Which seems to be present.
So I'm out of moves. Please help!
PS: Some additional info inspired by #Dhrubo 's answer:
The test I'm trying to run indeed sits in the main java folder of the library. (I moved it here hoping that when running from here it would be easier to find the package)
If I'm trying to compile the test instead of running it with JUnit he seem to fail to find JUnit classes and other JUnit related stuff.
[Oh OK I'm an idiot! Dont't mind me]
You should include the package while running StandardEvalTest.java as below
javac -cp [classpath] org.pokersource.game.StandardEvalTest.java
and run it from package root directory, I am assuming it is custom java file that you want to compile. You run directory should be parent of your package directory.
** I also see, you are trying to compile StandardEvalTest.java instead of Deck.java ... then check your StandardEvalTest.java file whether it exists in desired location.
http://nlp.stanford.edu/software/openie.shtml generates compile time error :
SemanticGraphCoreAnnotations.EnhancedDependenciesAnnotation cannot be resolved to a type
I am running java-8 under eclipse 2016. corenlp-full-2015-12-01.zip, openie.jar, openie-models.jar are in included in my eclipse project.
Error generated by line of:
System.out.println(sentence.get(SemanticGraphCoreAnnotations.EnhancedDependenciesAnnotation.class).toString(SemanticGraph.OutputFormat.LIST));
thanks
If I were to guess, this sounds like a classpath issue. What happens if you remove either openie.jar or the corenlp distribution? In theory, openie.jar should contain everything you need to run the Open IE system.
I have the same error.
What does this package edu.stanford.nlp.naturalli; in the first line of the code snippet mean?
I do not have much Java knowledge, I just created a Java project somewhere and included the same files as WH Sweet did.
I just found that within the corenlp project subfolder naturalli there is a OpenIEDemo.java already. Maybe the explanation for this would solve the initial problem..
I downloaded and compiled JTransforms-3.0 into my project and I can see it in the hierarchy here:
I'm running into issues on when I try to import it.
import edu.emory.mathcs.jtransforms.fft.DoubleFFT_1D;
It says it cannot resolve the symbol "edu" and I can get an error saying that the package doesn't exist. I'm using android studio and I have the libraries in my gradle file under the dependencies. Can anyone help? Thanks.
I don't know if you solve the problem still but I had to go through the same path as well. I ended up going to the Jtransform's GitHub page and downloading the "JTransforms-3.1-with-dependencies.jar" file. Placing it in the "libs" folder, right click "Add as a library" and works perfectly! :)
JTransform's github page
It should be imported like this:
dependencies {
...
implementation 'com.github.wendykierp:JTransforms:3.1'
}
Hi I am getting the error taskdef A class needed by class org.apache.jasper.JspC cannot be found: Could not initialize class org.apache.jasper.JspC when I tried to build the build.xml file. can anyone please give me a solution. Thanks in advance
I added the following to my ant classpath:
/usr/local/apache-tomcat-7/bin/tomcat-juli.jar
I had this problem too, but it was a long time ago and unfortunately my memory has become quite foggy on the subject.
As I recall, you need to start ANT with the -lib command line switch and have it point to some jar files that are needed by Jasper's JSP compiler. Again, I don't remember exactly which ones, but I think the JDK's tools.jar was one of them, as well as all the jars with jasper in the names, and commons-logging.jar and commons-el.jar. You'll have to do some experimenting :).
Do you have the required Jasper libraries in your classpath?
That is a relatively high level exception. If you would like to know more detail about what is missing from your classpath, you can run ant with the -verbose flag on the commandline.
It would be good to see the build.xml that you are using. Apache has put an example out here, which sounds similar to what you are using. If so, it requires that you specify some vars.
For this example Apache suggests:
The following command line can be used to run the script (replacing the tokens with the Tomcat base path and the path to the webapp which should be precompiled):
$ANT_HOME/bin/ant -Dtomcat.home=<$TOMCAT_HOME> -Dwebapp.path=<$WEBAPP_PATH>
If you are getting this error in eclipse "taskdef A class needed by class org.apache.jasper.JspC cannot be found: Could not initialize class org.apache.jasper.JspC",
jasper-compiler.jar consists of "org.apache.jasper.JspC", so please copy the commons-collections.jar in the same dirctory.
jasper-compiler.jar will be in C:\jboss-4.0.2\server\default\deploy\jbossweb-tomcat55.sar.
Hope it will resolve the issue.
