Problem in running javac.exe

Hi
I'm using Windows 2000 server.
I installed Java 2 sdk in directory c:\jdk1.2.2. After this I added
c:\jdk1.2.2\bin in the path environment variable using Control Panel ,System Utility.
Then I opened the command prompt (Start ,Run ) and typed command in the box:-
Steps:
1.Start ->Run
2. Typed command in the box
Now when I tried c:\> javac Hello.java it gave the foll. error:-
javac is not an internal or external command.
But when I tried to run javac using cmd instead of command in the start->run box it works fine
1.Start ->Run
2. Typed cmd in the box . Now javac Hello.java worked .
My Question is why it works with cmd and why not with command
Please help

cmd is the win2k console. it carries all system settings from wn2k. command is a dos box. it wont have the path settings u did for java

"Error running javac.exe compiler" when using ant to compile Eclipse plugin

Hi
I encounter an error "Error running C:\jdk1.5.0_06\bin\javac.exe compiler" when building my project using ant1.7.
My project has 10 eclipse plugins, and each plugin is compiled by invoking following ant target

<target name="compilePlugin">
     
     
     <delete dir="${param.plugin.dir}/${build.dir}" quiet="true"/>
     
     <delete file="${param.plugin.dir}/${param.plugin.targetJarFile}" quiet="true"/>
     <mkdir dir="${param.plugin.dir}/${build.dir}"/>
     
     <javac      srcdir="${param.plugin.dir}/${param.plugin.src.dir}"
               destdir="${param.plugin.dir}/${build.dir}"
               failonerror="${javacFailOnError}"
               verbose="${javacVerbose}"
               debug="${javacDebugInfo}"
               deprecation="${javacDeprecation}"
          optimize="${javacOptimize}"
               source="${javacSource}"
               target="${javacTarget}"
               fork="${param.fork}" memoryInitialSize="256m" memoryMaximumSize="512m">
          <classpath refid="compile.classpath" />
     </javac>
     
     <copy todir="${param.plugin.dir}/${build.dir}" failonerror="true">
          <fileset dir="${param.plugin.dir}/${param.plugin.src.dir}" excludes="**/*.java, **/package.htm*" />
     </copy>
     <jar jarfile="${param.plugin.dir}/${param.plugin.targetJarFile}" basedir="${param.plugin.dir}/${build.dir}"/>
     <delete dir="${param.plugin.dir}/${build.dir}" quiet="true"/>
</target>
Since each of first 9 plugins contains less than 500 java source files, we always set "param.fork" to false when invoking this ant target.
For the 10th plugin, it has about 1000 source files. If we set "param.fork" to false, we will get the error "Error running javac.exe compiler". So we have to set "param.fork" to true when compiling it. This week, this plugin contains about 1250 files and we get the same error again when compiling it. I tried to increase the "memoryMaximumSize" to "768", but still couldn't get through it.
BTW, There are about 150 jar files in our classpath for compiling plugins. Do many jar files cause this problem?
Any help is highly appreciated.
Many thanks
Oceanman

I encountered a very similar error and I was able to resolve it by removing the following parameters from the javac task:
fork="${param.fork}"
memoryInitialSize="256m"
memoryMaximumSize="512m"My values were not the same as yours, before I removed them, the values were set to:
fork="true"
memoryInitialSize="256m"
memoryMaximumSize="256m" Not sure why this fixed my problem but it did. I was using Ant 1.7 and Java 1.6_07 hope this helps.

most likely the javac executable is not on the system path. Try typing 'javac -version' in a command prompt and see what response you get.
If it is something like 'javac is not a recognized...', locate where the JDK is installed and add its bin subdirectory to the PATH system variable. Restart any command prompt and type javac again.
You DID have a JDK installed, didn't you?

RFE: faster javac compilation using invocation instead of running javac.exe

Sun's JDK contains the Java compiler in tools.jar.
Why not use it instead of running javac.exe?
It should also simplify the code for cross platform compatibility...
Regards,
Yaniv Kunda

I meant that JDev would invoke the compiler from the libs of the project JDK.
But this is indeed a sort of a hack because the libs are not documented and are sun-specific (a problem with other JDKs).
Anyway, I was just reading a bit on Java 6 (Mustang) and saw that an API (per JSR-199 : http://jcp.org/en/jsr/detail?id=199) for java compilation is one of its new features!
This feature is documented in http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4164450.
I guess it would be a feature for a newer major release of JDev, but nevertheless important to mention.

I have a problem with running an EXE file on win2000, the Lab View is 5.1 and I do not know if it is 16 bit...

I have a problem with running an EXE file on win2000, the Lab View is 5.1 and I do not know if it is 16 bit...what should I do?

Hi Arika,
The drivers that you need to install to make your executable work depends on what your executable is doing. To get started, you need to have the LabVIEW Run-Time Engine installed on your target machine (the Win2000 machine you are planning to use) in order to run your executable. Next, you need to determine what drivers your executable uses, if any. For example, if you are using GPIB instrument control, you will need to install the NI-488 drivers on your target machine. If you are performing data acquisition, you will need to install NI-DAQ drivers. If you are doing image acquistion, you will need to install NI-IMAQ drivers.
All these drivers are available for downloading on ni.com. To get the drivers, go to ht
tp://www.ni.com/support , click on the link that takes you to Drivers and Updates (under Option 3), and click on the links to get to the driver(s) you need. For example, if you need the LabVIEW 5.1.1 Run-Time engine, click on the All Drivers and Updates by Application link on the main page (http://www.ni.com/softlib.nsf/). Then click on the LabVIEW link, Windows 2000, Run Time Engine, and then you will see the link to get to the page to download the LabVIEW 5.1.1 Run-Time Engine.
I hope this information helps.

Problem with running rhcl.exe in batch file

Hi,
I'm running Robohelp 8 and trying to use rhcl.exe to generate multiple help projects. I'm having a problem with the folder where the rhcl.exe is generating the web help. It seems to ignore the "-o" switch and gets the generation folder from the project all the time. As you can see from the log file below, the exe appears to pick up the "-o" path (......\Test\Opportunities.htm), but writes the generated files to the path in the project (.....\Opportunities\index.htm).
Anyone else come across this problem?

Application Builder 7.1: problem when running an EXE

Hello,
I have developped a VI on a computer with LabView 7.1. The VI uses an USB 6008 (with DAQmx base 1.4 drivers.) to measure signals. It perfectly works. Now I've spent a lot of trying to put the system on a computer that doesn't have LabView installed.
-I first installed the USB 6008 drivers on the computer
-Then I made an installer with the application builder (including the run-time engine)
-Once the application is installed on the new environnement, I just keep on having error messages when running it.
-first it doesnt find all the DLL, you have to copy them from the PC with LabView in C:\windows\system32\. Done.
-then I get this big dialog box with a listing of sub-Vi missing, such as: Sub-VI Create Task.vi missing in VI Instance 1 6ProgName.v1
I've looked into the LLB file created with the builder: all these sub-VI are here!! Why won't it work?
What can I do to solve this?? Thanks for your help.

Hi batsenn,
for the missing dll: what are those dll's? you may need to install additional run-time packages, or check some more component in the Advanced Installer Settings form, depending on your application.
Now for the main problem: are you calling vi's dynamically from an external LLB? in many cases when a file is not found from the built application, it's a path problem. In fact, if a vi path is e.g. c:\mysourcedir\myvi.vi, when the EXE is built the path will be something like c:\myexedir\myexe.exe\myvi.vy. You see that there is an additional Strip Path you need to do if you are getting the current path from a vi path.
What I said can be relevant or not depending on the vi calling techinique you are using. A suggestion is to execute the built EXE on the development computer (where all components are present) to check if the problem is still there.
Hope this helps.

Computer restarting when running javac.exe

Hi...i am new to Java.
I have a problem, when I compile my java file using javac myfilename.java then suddenly my computer restarting itself...
This happens many times on my computer...Is there anybody know the reason?
Thanks

This is an odd problem. Apart from viruses, the usual reason for an unexpected restart is some kind of driver problem, since in XP this often triggers an automatic restart instead of a blue screen (what a creative approach to ridding the world of the BSOD ;-)
It doesn't seem likely to be a graphics problem, since it occurs with non GUI apps, but just so you know, ATI cards are particularly prone to trouble.
Install any pending service packs, and update your SDK to 1.4.1_02 if you haven't done so already. Change your graphics drivers to the newest available set.
That should knock the problem on the head, hopefully.

Hi,
It seems for windows 32 bit OS there is no installation options for NW7 EHP2

I think its better to have a 64 bit machine or install lower version of SAP.

Facing problem with running exe from my java code

Hello,
I have to run the exe from java code for which I m using Runtime and Process classes. The exe runs in the following way on command line
C:/ myexe -j [now press enter]
input sentence followed by ! [now press enter]
And after this exe gives the output.
So is there any way to achieve this programmatically in Java?
Thanks in advance.
Regards,

I m confused .. how can i pass input to the Process through InputStream? I think it will need OutputStream for that.
Here is my code...
import java.io.*;
class CallToExe
static BufferedReader br;
public static void main(String[] args)
File F = new File("C:/Chasen.exe");
try
if( F.exists())
     System.out.println("Exe exists");
     Runtime rt = Runtime.getRuntime();
     Process proc = rt.exec("C:/chasen.exe");
     br = new BufferedReader(new InputStreamReader(in));
     int a = in.read();
     System.out.println(a);
     String res = br.readLine();
     System.out.println(res);
     while(!res.equals(null))
     System.out.println(res);
     res = br.readLine();
proc.waitFor();
     proc.destroy();
catch(NullPointerException npe)
     npe.printStackTrace();
catch (Exception IOEx)
IOEx.printStackTrace();
But it doesnt work as my chasen.exe needs arguments from stdin.
The way exe works is as follows.
on command prompt>>
C:/chasen.exe -j [ Need to press ENTER here]
input statement . [ Need to press ENTER here too]
Then output is displayed on command prompt which can be taken from InputStream of the process. But I m not able to properly run this exe itself with all the arguments frm Stdin

Problems to invoke java.exe from Java application, but ok for javac.exe??

Having problems with javac.exe??

hey.....I cannot use any text editor to compile in either windows me, or windows xp...appearently, javac.exe is missing from file path C:\Windows\System32\javac.exe??? any advise??please?!?!is this a windows thing?

This probably is a windows thing. You need to add the jdk/bin directory to the system path variable.

Can't find Javac.exe

I'm new to Java (presently taking a class). I'm very confused and not getting too far. I'm running Win XP and have downloaded the latest version of Java J2SE1.4.0_01 (actually because of repeated problems, I've uninstalled and installed it a few times).
I can't find javac.exe anywhere on my c drive. I read a past forum posting describing the same problem which suggests downloading the latest version of SDK1.4. Isn't this what I have been downloading? Where can I find this download? If it isn't what I've been downloading, why do I need both and how would I have known this? I understand how to set the path once I get javac.exe but I'm becoming frustrated trying to obtain this file and move forward with my study of java. Thanks for the help.

If you need only to run a java application then you just need a JRE (Java Runtime Enviorment ). It contains everything that you wanted to run it.
But, if you want to develop some java application , then you needs something more... you need to have to compile those source files first... For this what you want is a SDK (Software development Kit)... Both is free.. You can download the 1.4sdk from http://java.sun.com/Download6
After downloading and installing it, set the path corectly to include the bin directory of the installed folder..
Hope it helped
