How to fix javac package does not exist?

I am creating in my code a Java file, which I need to convert to a class. My file contains the following:
import com.company.tpch.TpchApplication;
import com.company.tpch.TpchApplicationBuilder;
import com.speedment.runtime.core.ApplicationBuilder;
public class java {
public void x() {
TpchApplication app = new TpchApplicationBuilder()
.withPassword("root")
.withLogging(ApplicationBuilder.LogType.STREAM)
.withLogging(ApplicationBuilder.LogType.APPLICATION_BUILDER)
.withSkipCheckDatabaseConnectivity()
.build();
}
}
When I try to compile the file with
javac -d . C:\Users\s\Desktop\demo\src\main\java\java.java
I have these errors:
import com.company.tpch.TpchApplication;
^
C:\Users\s\Desktop\demo\src\main\java\java.java:2: error: package com.company.tpch does not exist
import com.company.tpch.TpchApplicationBuilder;
^
C:\Users\s\Desktop\demo\src\main\java\java.java:3: error: package com.speedment.runtime.core does not exist
import com.speedment.runtime.core.ApplicationBuilder;
^
C:\Users\s\Desktop\demo\src\main\java\java.java:7: error: cannot find symbol
TpchApplication app = new TpchApplicationBuilder()
^
symbol: class TpchApplication
location: class java
C:\Users\s\Desktop\demo\src\main\java\java.java:11: error: package ApplicationBuilder does not exist
.withLogging(ApplicationBuilder.LogType.APPLICATION_BUILDER)
^
C:\Users\s\Desktop\demo\src\main\java\java.java:10: error: package ApplicationBuilder does not exist
.withLogging(ApplicationBuilder.LogType.STREAM)
^
symbol: class TpchApplicationBuilder
location: class java
How can I solve this?

You need to add all classes that are used to your command. Like this:
javac com/company/tpch/TpchApplication com/company/tpch/TpchApplicationBuilder java.java
Of course you have to change this according to your directory structure, since I don't know it.
Anyway I would recommend an IDE that compiles your whole project at once like IntelliJ/Eclipse and/or a dependency tool like Maven/Gradle.

junit - test won't run and receiving lots of errors

I have downloaded my old project that was built on a different computer. I have Java environment installed on the current one. I have also downloaded junit to get things work. When I run my tests using build.rb and run_test.rb - files that worked previously, I receive lots of errors negating the entire code. Here's the example
$ ruby build.rb
shop_basket\Cashdesk.java:4: error: class CashDesk is public, should be
declared in a file named CashDesk.java
public class CashDesk{
^
1 error
shop_basketSpec\CashdeskTest.java:5: error: class CashDeskTest is public,
should be declared in a file named CashDeskTest.java
public class CashDeskTest{

shop_basketSpec\BasketTest.java:2: error: package org.junit does not exist

shop_basketSpec\BasketTest.java:3: error: package org.junit does not exist
import static org.junit.Assert.*;
^
shop_basketSpec\CashdeskTest.java:2: error: package org.junit does not exist
import org.junit.*;
^
shop_basketSpec\CashdeskTest.java:3: error: package org.junit does not exist
import static org.junit.Assert.*;
^
shop_basketSpec\CashdeskTest.java:7: error: cannot find symbol

shop_basketSpec\CustomerTest.java:2: error: package org.junit does not exist

shop_basketSpec\CustomerTest.java:3: error: package org.junit does not
exist
import static org.junit.Assert.*; ^
shop_basketSpec\ProductTest.java:2: error: package org.junit does not exist
import org.junit.*;
^
and there are more errors like this as if they concerned the entire code structure. I don't get why.
All the CLASSPATH etc seems to be set on my windows OS. The entire thing irritates as I cannot move with my coding. Thanks for help
Here's my set CLASSPATH

For the first two errors relating to CashDesk and CashDeskTest - your file names have a lowercase 'd' (Cashdesk.java and CashdeskTest.java). The casing in the file name should match the actual class names as declared in the code. Fix that.
If you still see JUnit errors afterwards, check that you have a JUnit JAR on your classpath.

Errors Cashdesk.java:4: error: class CashDesk is public, should be
declared in a file named CashDesk.java are caused by inconsistency between .java file names and public class which it contains. In this exaple class CashDesk is saved in Cashdesk.java file - note d vs D in Desk.
The second bunch of errors error: package org.junit does not exist mean you should include JUnit library to the classpath of your project

Java: Compiling and running multiple packages from the command-line

I created multiple packages and want to compile and run them. I fiddled around with javac and java and learned about how packages should be named and how a project should be structured. I hope I got all right. But I fail at compilation and running the stuff. I know I could use an IDE for this, but I want to try it with the command-line tools just for curiousity.
Here is how my project is organized:
Project
+ src
+ net
+ chris
+ dojo
- Program.java
+ datastructures
- Queue.java
- LinkedList.java
+ sorting
- MergeSort.java
+ bin
+ net
+ chris
+ dojo
- Program.class (should be here but missing because compilation fails)
+ datastructures
- Queue.class
- LinkedList.class
+ sorting
- MergeSort.class
Compilation for the classes in the "datastructures" and "sorting" packages is working fine. Here are the commands I used. The folder structure in the "bin" folder is automatically created by the compiler.
javac -d bin src\net\chris\dojo\datastructures\*.java
javac -d bin src\net\chris\dojo\sorting\*.java
The problem is when I try to compile "Program.java" (thats the test class I run from the command-line) the compiler is throwing errors, because it cannot find the packages "net.chris.dojo.datastructures" and "net.chris.dojo.sorting".
Here is the compilation command:
javac -d bin src\net\chris\dojo\Program.java
This is the output I get:
src\net\chris\dojo\Program.java:3: error: cannot find symbol
import net.chris.dojo.datastructures;
^
symbol: class datastructures
location: package net.chris.dojo
src\net\chris\dojo\Program.java:4: error: cannot find symbol

src\net\chris\dojo\Program.java:13: error: cannot find symbol
LinkedList list = new LinkedList();
^
symbol: class LinkedList
location: class Program
7 errors
Thats the code of my class files:
Queue.java
package net.chris.dojo.datastructures;
public class Queue {
...
}
LinkedList.java
package net.chris.dojo.datastructures;
public class LinkedList {
...
}
MergeSort.java
package net.chris.dojo.sorting;
public class MergeSort {
...
}
Program.java
package net.chris.dojo;
import net.chris.dojo.datastructures;
import net.chris.dojo.sorting;
public class Program {
public static void main(String[] args) {
int[] values = { 9, 4, 6, 2, 0, 3, 8, 1, 7, 5 };
MergeSort.sort(values);
Queue queue = new Queue();
LinkedList list = new LinkedList();
}
}
I would run it with this command:
java -cp bin net.chris.dojo.Program
I execute all commands in the root folder of the project.
Thanks for your help.

The solution was to include the classpath when compiling. That way it can find the packages it depends on.
javac -d bin -cp bin src\net\chris\dojo\Program.java
Thanks #BigMike for the solution.

Try change this in your Program class
import net.chris.dojo.datastructures;
import net.chris.dojo.sorting;
to
import net.chris.dojo.datastructures.*;
import net.chris.dojo.sorting.*;
And when you compile your Program.java use following command
javac -d bin src\net\chris\dojo\Program.java -classpath bin

Declare external libraries in Java - Compiling Error

I can't compile my Program.java from the command line (only in Eclipse).
When I want to compile it with
javac Program.java
"cannot find symbol" errors occur at JUnit classes.
Eclipse has the JUnit classes in it's plugins, but to compile it on my own I would need to somehow compile my JUnit.jar with the program. How can I do that? It doesn't seem to work with
javac -cp absolutePathTo\JUnitJar Program.java
Or is this problem maybe caused because the JUnit classes are not implemented in my (nested) new Thread classes?

While using javac command with external jar, you should use
javac -classpath path-to-external-jar/jarname1.jar;/path-to-external-jar2/jarname2.jar Program.java
same for java command:
java -classpath path-to-external-jar/jarname1.jar;/path-to-external-jar2/jarname2.jar Program

Now I got it to work.
I renamed junit-4.10.jar to junit.jar, moved it to another folder and somehow this solved the problem:
javac -classpath "C:\Documents and Settings\x\Desktop\eclipse\x\Program\extres\junit.jar" src\data\Program.java
BTW:
When I'm in C:\Documents and Settings\x\Desktop\eclipse\x\Program\ it also works with:
javac -classpath extres\junit.jar src\data\Program.java

You really need to learn more on the topic of the Java CLASSPATH. Your errors, both at compile and at run time, are due to you not providing the complete classpath.

Check if the Axis library really is in D:\stub\src\org\apache\ws\
...and try using double-backslashes: D:\\stub\\src\\org\\apache\\ws and d:\\lib
I can't re-create your problem since I'm using Linux, and I remember Windows users having backslash issues sometimes.

IIRC, the axis stub generator is old, and generates pre 1.5 (maybe even pre 1.4) java source code. Try setting the source flag, and see what happens.
