I've been trying to get Jetty to run my web app via a custom launcher (embedded). I am trying to figure out how to tell Jetty which java compiler to use for JSPs. I want to do what java -jar start.jar -OPTIONS=jsp does, but without using start.jar. Here is what shows on the console: Javac exception, Unable to find a javac compiler; c...
Q.1. What free compiler produces the most optimal Java bytecode? Q.2. What free virtual machine executes Java bytecode the fastest (on 64-bit multi-core CPUs)? Q.3. What other (currently active) compiler projects are missing from this list: http://www.ibm.com/developerworks/java/jdk/ http://gcc.gnu.org/java/ http://openjdk.java.net/g...
This is annoying. I have a directory structure like this -lib --some jar files -packageName --Main.java --SomeOtherPackage --SomeOtherJavaClass.java Main.java imports SomeOtherPackage. And both java files uses jars in the lib. What I do is add the jar files independently in the CLASSPATH. And then run as: javac packa...
Hi I am looking looking into the options for tweaking the performance of JBoss 5.1.0 and one of the options available to me is to disable the generation of debug information when compiling JSPs. I know that the presence/absence of debug information for the JVM makes no real difference, but does the generation of that debug information ...
I have looked for an answer for this nearly every where that I can think of, but there doesn't seem to be any way to actually SEE what Eclipse "runs" to compile the projects (as it does need the JDK installed and visible to actually build). I ask because I imported a few jars into my project, and even though I've looked through all the j...
In Java this is the case: public void method() { if (condition) { Object x = ....; } System.out.println(x); // Error: x unavailable } What I'm wondering is this: Is the fact that x is limited to the scope of the if-statement just a feature of the Java compiler, or is x actually removed from the stack after the if-statement? ...
I asked this in a comment, but figured it's a separate question: Is Eclipse's compiler just a wrapper around the same compiler core that the javac program is wrapped around, or is it a separate compiler altogether? If the latter, why would they reinvent the (possibly inferior) wheel? ...
Hey All, I have a Java project that contains many very large source files and it compiles fine in Eclipse, however it will not compile with javac from the command line or within Ant. When I try to compile it from the command with javac (or using Ant) I get a StackOverflow Exception: [javac] java.lang.StackOverflowError [javac] ...
Is this valid Java? import java.util.Arrays; import java.util.List; class TestWillThatCompile { public static String f(List<String> list) { System.out.println("strings"); return null; } public static Integer f(List<Integer> list) { System.out.println("numbers"); return null; } publ...
Hi All, I have a Java file,which when I compiled, I will be able to see only first 100 errors on console after that java compiler(javac) exits. How will I be able to see all the compilation errors on console? Thanks in advance- opensid ...

But, when i use dos command prompt in the following way: javac -cp jgrapht-jdk1.6.jar HelloJGraphT.java it compiles. But, if i run it using: java HelloJGraphT it gives the fol...

I am just trying to compile and run a very simple test program, but it simply will not work, and I have no idea what the problem is. I have a java project that's been heaped on me, and I know little to nothing about java. Especially compiling from the windows command line. I have two Jars that I need to compile a simple "hello world"...
I'm using notepad++ to learn java, I have it set it up to compile and run java from the Run menu, only that I have been coding small exercises w/o external libraries, I know I have to use -classpath to tell the compiler what library to use, but I was wondering if there is any way to tell the compiler to "use" the libraries in the lib dir...
I have a project where I am responsible for fixing some errors and another developer is responsible for other errors. The number of errors is well over a hundred, and as I'm fixing my errors, her errors are piling up. I'm at the point where I see 99 of her errors and one of mine, and I assume I will soon get to a point where it is 100 ...

EDIT: I ended up setting up the whole project in Eclipse and was able to get it to build. I'm not sure why this problem occurred and hopefully I'll never have to find out. I'm having a problem where my build is reporting "BUILD FAILED" without reporting any errors. I'm building a large application of a lot of old code which I now have...
I'm writing a makefile that compiles a .java file in a different directory, and then I want to run it without changing directories. I want to do something along the lines of: $(SQM_JAVA_TOOL_DONE) : $(SQM_JAVA_TOOL) $(shell cd /home_dir) javac myjavafile.java java myjavafile where the java file is /home/myjavaf...
