package does not exists - netbeans

[emosms]

Hi, Trying to add a library to a java project.

The original library didn't have a package for the classes, it was all in a <default package>
So I opened the jar archive, put the classes in a new folder and made a .jar file again.
Now my classes are jarred within a 'stdlib' folder. Added to all clasess 'package stdlib;' on top of the text.

But: http://s9.postimg.org/pjzebpz33/lib.jpg

netbeans says - package does not exist.
The library is added to the project.
There is a folder with the corresponding name inside the jar, containing the referenced classes.
Finally, don't know what to do now, except dragging the classes needed into my project sources :)

Best Regards

it doesn't contain classes, it contains java source files apparently.

Thx,
I compiled some classes I need and it works.
But when trying to compile some of the other classes, I get an error like this:
---
E:\workspace\alg4e\stdlib_>javac BinaryStdIn.java
BinaryStdIn.java:261: error: cannot find symbol
BinaryStdOut.write(c);
^
symbol: variable BinaryStdOut
location: class BinaryStdIn
BinaryStdIn.java:263: error: cannot find symbol
BinaryStdOut.flush();
^
symbol: variable BinaryStdOut
location: class BinaryStdIn
---
It refers to the class 'BinaryStdOut', which is allready compiled and present as 'BinaryStdOut.class' file in my package/folder.
What could be wrong??

Do those classes in the stdlib package actually have a package statement at the top of them?

[emosms]

all of them do.
manually added 'package stdlib;' in the .java files.
Sometimes I get ciricular references.
Trying to compile class A yields some ref. to Class B error, Trying to compile Class B prints some ref. to Class A error :)

[gimbal2]

post the code of those classes that don't compile, because they obviously contain mistakes. Take a look at the error you are getting and the line of code it points to:

BinaryStdOut.write(c);

symbol: variable BinaryStdOut

variable? BinaryStdOut is a classname, not a variable. I would expect the code to be more like:

BinaryStdOut stdOut = new BinaryStdOut(...);

stdout.write(c);

BinaryStdOut is successfully compiled. Source:
Free Text Host - The Anonymous Text Hosting Service - No Registration Required
BinaryStdIn won't compile:
Free Text Host - The Anonymous Text Hosting Service - No Registration Required
- Both declared as final classes, static methods only, no instantiation

Please go through the http://www.java-forums.org/forum-gui...w-members.html and BB Code List - Java Programming Forum - Learn Java Programming and then post the code and any error messages here on the forum.

Ok, I will consider that - BB code. Eventhough it makes the post insanely big if I post all the code inside.
Got the problem:
The classes have package specified, so the new class to be compiled is looking for the source to be in a direcory named as the package declared.
That's why there are errors, it does not find the referred classes (variables?) in such a directory.
---
Still cannot figure out how to make it in a batch.
If I use the jar -d option and set a directory, it places the file in a new directory with the same name within my existing package directory.
The package directory with the coresponding package name MUST exist in advance.
So again, with this option the files created are one step deeper and it seems completely ridiculous behavior to me.

I guess you need ot go through this Lesson: Packages (The Java™ Tutorials > Learning the Java Language)
