Java won't compile for me
hi. I'm new to Java. Installed JAva from a book's CD. Java1.3. When I compile, I get an error message saying "bad command or file name". It doesn't compile. Thank goodness for the book's exercises being on CD. The .class files are already there, whichmeans the .java files were already compiled, yes? (i'm new) So, running Java with these already compiled files works fine. It's just compiling that is the problem. I suspect it has something to do with my settings in my autoexec.bat file, but what do i know? I'm new!
Can somebody help me out?
I can't keep checking this forum yet, so i'd prefer to be emailed at [email protected]
Thanks, Christian
this is the first version of my autoexec.bat file that i tried:
@ECHO OFF
SET PATH=C:\IBMTOOLS
If Exist C:\MFGBOOTI.REG C:\WINDOWS\REGEDIT C:\MFGBOOTI.REG
PATH=%PATH%;"C:\Program Files\Mts"
PATH C:\jdk1.3.0_02\bin;%PATH%
SET CLASSPATH=%CLASSPATH%;.;C:\jdk1.3.0_02\lib\tools.jar
this is the second version :
@ECHO OFF
SET PATH=C:\IBMTOOLS
If Exist C:\MFGBOOTI.REG C:\WINDOWS\REGEDIT C:\MFGBOOTI.REG
PATH=%PATH%;"C:\Program Files\Mts"
PATH C:\jdk1.3.0_02\bin;%PATH%

Java 2 SDK compilator for beginners
Hi to all here.
I am really sorry to disturb you all,
I am beginner in Java and I need to download Java 2 SDK compilator in order to compile my homeworks. I went lost in all the reliese EE, SE and so on I saw in Sun homepage.
Which one is the right one ?
I have Windows Vista Home edition in my computer.
Thanks for helping me.
FlavioDownload and install a Java SE 6 JDK for your Windows platform which is available here:
http://java.sun.com/javase/downloads/index.jsp
If you want some GUI Application you may choose the version containing NetBeans, if you only want the compiler and runtime environment install the first option (JDK 6 Update 4).

I'm using J2SE 1.5.0 with NetBeans 5.5 so they all should be there. I'm following the example at http://userpage.fu-berlin.de/~ram/pub/pub_jf47ht9Ht/evaluating-expressions-with-java since all I want to do is come up with a Java equivalent of "eval()", which I use in PHP whenever I need it.
Help appreciated, I'm lost here.
Thanx
PhilHow do you do the Java equivalent of eval()?The language provides no support for that.
Reflection lets you call any method, where you
specify that method's name as a string and go through
a few other steps to build the proper Method object
with the proper args.
(http://java.sun.com/docs/books/tutorial/reflect/) It
won't let you just evaluate Java source code as a
script interpreter though. To do that, see
www.beanshell.org. Jython and I think Ruby on Rails
also give you scriptingin Java. Jython uses Python's
syntax, but gives you access to your Java classes. I
don't know ayhthing about RoR.I am going to look up PHP/Java myself as I know no Python right offhand (but probably could learn it in about 10,000 years). Tried to figure out reflection but couldn't figure out how to do what in PHP we do like this:
$msg = eval('JButton ' . $nameArray[$i][0] . ' = new JButton("' . $nameArray[$i][1] . '");'); -

I used the javac command in dos mode to compile my .java files , but in my recent program i have so many errors that they dont fit into the dos screen(in dos mode i cannot move up and down!).
Is there any simple compiler for windows(or GUI) that could solve my problem?If you haven't done this already you can right click on your Dos Prompt icon and go to properties, then go to Screen, then change the initial size of your prompt to the largest it will go, (50 lines I think). That might give you a little more room...

Robohelp for Word won't compile
Hi,I've been trying to get one of my projects to work in Robohelp for Word. But the minute I create a second topic the compiled doen't work. there are no errors. the compilation just never starts. This also happens when I rename the first topic to something else.
I have the following configurations:
Robphelp for Word 7 build 145
MS Office Work 2007
windows XP professional with service pack 3
I have deleted and started the project from scratch several times without any success. Any help would be highly appreciated
Thanks
EdnaHi,
Thanks for your reply. The problem is there even with tutorial files and dummy projects.
It seems that there is a problem with saving the document. If I don’t add anything the projects will compile problery. But the minute I change something it won't compile. When I want to close the word document I get a meesage saying if I would like Robohelp to save the document. If I press on "yes" nothing happens. If I press on "yes to all" nothing happens. Pressing on "no" closes the document.
I have setup my word 2007 in a way so it will save .doc formats instead of .docx. But either way it makes no different the problem is with both file formats. -
Can anyone tell me where i can get an compiler for the mac os x?

How do I set javac to compile for older versions of java?
I need to compile a ".java" file for version 1.4.0 of java in order to run it on Nintendo DS. However, my version of java is 1.6.0.
In resume, I need to set javac to compile for version 1.4.0, but I haven't had much success figuring it out myself, so if anyone knows this, please?WalterLaan wrote:

++++ that.
Using the -source/-target options are not a guarantee that the specified JRE will have the required classes, methods and attributes available. Those options only ensure the classes have a format that is 'reabable' by the target JRE.
Using the -bootclasspath option guarantees the classes are not only readable, but that the VM will not throw 'NoSuchMethodError's or equivalent, at run-time. -

these files WILL compile if i use an IDE. i tried jGRASP and they compile and run fine.
what do i do to fix this?
(xp pro)For classpath, you can shorten the word to "-cp", I
believe (it doesn't work on our Java at work, becauseNo, that will not work in this case!
-cp only works on the java command (to execute Java programs), not on javac (the compiler). Stupid, isn't it?
Make sure that your CLASSPATH environment variable is not set - that will make Java use the current directory as the default, and you won't have to type "-classpath ." every time.
If you're starting a serious project with lots of source files, I suggest you have a look at Ant to manage your build process. -

Sorry, I appreciate your help and should have thought more carefully about offending people.
No offense taken. It is just that many people who post here only do so out of frustration and really only want to rant. They are unwilling to step back and take a more logical and reasoned look at a problem. I'm not going to bother reading rants, but I will be glad to help anyone who will meet me halfway.
However, I deeply dislike XCode, for numerous reasons:
I'm pretty ambivalent about Xcode. I've seen better and worse IDEs. It would probably be better if there were some competition around, but Metrowerks put themselves out of business.
Xcode certainly has its faults, but what you have described is not behavior that I have experienced or that I have ever heard about.
*This same exact project compiled fine on another computer (which unfortunately has been wiped clean)
I have to say I'm skeptical about this. How do I (or you) know that there wasn't some fix not checked in to SCM on the other machine? Or some change that didn't work but did wind up in SM?
*I'm able to build successfully on Leopard, just not my computer running Tiger. However, when I do the build on Leopard, it won't run on Tiger (I get missing link errors at runtime), even though I specify 10.4 as the target SDK.
One way to narrow down where the problem might be is to build a test application on each system and make sure that works properly. How do I know you aren't one of those people who tried to pick and choose which parts of Xcode to install? You must install all of Xcode.
How do I know you haven't tried to run one of those nasty apps like Monolingual that strips out resources that "you don't need"?
*When I do the build in Tiger with 'current operating system' specified as the SDK, I get a completely about 800 error messages.
That indicates that either your project or Xcode installation is completely broken. The first thing to do is find out which one of those it is.
When I specify 10.4 as the SDK (which seems to me like it should be the same behavior as 'current operating system', since the machine is running 10.4), I get about 3,000 error messages as stated in my original post.
Given that you don't seem to be able to build anything, trying a cross-platform built is unlikely to work better. The 10.4u SDK is for building a Universal binary (PPC and x86).
*It is very difficult for me to figure out where to change various settings, since some are at the project level, some are at the target level, and some are at the build configuration level. Sometimes when I double-click on a target to change its settings, I get a blank editable text area; other times I get a GUI with modifiable target settings. In other words, I find the UI to be extremely difficult to manage.
Those are certainly valid complaints. Once you get past this initial problem of building, it might be a good idea to post one or more new threads about how to use Xcode more effectively.
In fact, when I've had to change certain settings in the past, it's faster for me to modify the project file in a text editor than to hunt for that particular GUI widget.
Given that you seem uncomfortable with Xcode, this seems like a pretty dangerous thing to do. You could easily wreck your project so that it stops building for mysterious reasons.
I'm much more comfortable with Java and IntelliJ than I am with C++ and XCode, so I'm sure that is a big part of my problem, but my gut reaction to the problems that I'm having right now is "don't breathe wrong on XCode or it will stop working and you have to recreate the project". That is why I don't like it (to put it mildly).
You normally shouldn't have to recreate projects just to get Xcode working. However, that might be what you need to do in this case. If you can definitively prove that Xcode is correctly installed - by building a set of simple 10.4, 10.5 and 10.4u applications, then your project must be corrupted.
Again, I appreciate your help. I only posted this rant to explain my previous post, which I should have kept to myself.
I know how you feel. I got someone else mad at me in another thread when I called pthreads "pathetic" -
FtpClient client.delete("file") won't compile?
Hello Fine People,
I have this ftp program that is working, except for the delete command:
import sun.net.ftp.*;
import sun.net.*;
String server = "192.168.0.0";
String user = "me";
String passwd = "mypassword";
FtpClient client = new FtpClient();
client.openServer(server);
client.login(user, passwd);
TelnetInputStream tis = null;
client.binary();
client.cd("Composites");
tis = client.list();
client.get("filename");
client.delete("filename");
This is roughly how it is. Without the last line, it compiles and runs fine. But when I add the client.delete line, it won't compile and gives this error:
ImageTransfer.java:229: cannot resolve symbol
symbol : method delete (java.lang.String)
location: class sun.net.ftp.FtpClient
client.delete("filename");
Please help!
- LoganYes. The class you should be importing is, obviously, FTPClient. But don't waste your time trying to compile what is clearly just a code fragment example. The article lists several sources of FTP client software. Once you have chosen one package to evaluate, write your test program using the actual classes from that package, using its API documentation for guidance.

Msg.addRecipient(Message.RecipientType.TO,to) - won't compile in program
I have had success in one of my servlets using JavaMail. I was able to send an email to my inbox to test it out. I proceeded to create another servlet based on that 1st one, and for reasons I can't explain, the servlet won't compile.
I get this error.
cannot resolve symbol :
variable : RecipientType
location : java.lang.String
msg.setRecipient(Message.RecipientType.TO, to); I get the same error when I switch out setRecipient for addRecipient.
However, through further testing, I've found that not only does my 1st servlet still compile, but I'm also able to run the code from the 2nd servlet, successfully in a JSP page. This is driving me nuts...how could there be a problem compiling? There's no reason why one servlet compiles (with similar if not almost exactly the same code) and the other won't. Plus this runs fine in a JSP page...what's going on??? I've spent hours on this and I can't figure it out...please help, any input is appreciated.
Here is the JSP page that runs successfully :
<%@page import="java.io.*"%>
