Java command line programming in windows

Here's what I want to do:
-write .java files in a text editor
-compile and run them from a command line, rather than using a
compiler like codewarrior or MS J++
Here's my problem:
In a program that produces output, I can't seem to find a way to
retain the output that goes off the screen in a DOS window. Is there
a way to enable scrolling in a DOS window, or are there any
alternative command line terminals for Windows? Any suggestions
would be greatly appreciated.

I think you can increase the Screen Buffer size which should give you a scroll bar. For this right click on the icon on the top left of the DOS window -select Properties - Go to Layout tab.
Another option will be to redirect the output to a file
java SomeClass > log.txt
Hope this helps.

JAVA command line options -cp and -jar don't work together?

Running JSDK 1.4.2 under Windows. I have a Java application that tries to dynamically load a class name that the user enters as follows:
try {
classResult = java.lang.Class.forName(strFilterName);
catch (ExceptionInInitializerError e) {
strErrorMessage = "ExceptionInInitializerError loading class: " + strFilterName;
catch (LinkageError e) {
strErrorMessage = "LinkageError loading class: " + strFilterName;
catch (ClassNotFoundException e) {
strErrorMessage = "ClassNotFoundException loading class: " + strFilterName;
This works fine if the classes that make up my application are left as class files in the classpath, but fails to work if they have been collected and run from a JAR file. Note: I can even dynamically load the class when running from the JAR file, if the class I'm trying to load is within that JAR file too. The problem really occurrs when the dynamically loaded class is located someplace else in my classpath. I've tried using various combinations of the "-cp" and "-jar" Java command line options - but when loading and running from a JAR file - the "-cp" parameters seem to be ignored. Is this a bug? Has anyone ever seen this before?
I run my program from the JAR file using this command:
java -cp .;e:\entmgr\filters -jar EntMgr.jar
Where "e:\entmgr\filters" is where the class I'm trying to dynamically load is. (This class has no package name, but loads perfectly as long as I'm not running the application from the JAR file). The class name specified by the user has to be fully specified with a package name (if it has one).
I have tried forcing the "java.lang.Class.forName(strFilterName);" call to use the system class loader, the parent of the system class loaded, and even the null bootstrap class loader - all with no success.
I am suspecting that the class loader that is loading and running my main program from the JAR file, is just not paying any attention to the "-cp" parameter when the "-jar" parameter is present. Indeed, I have never seen any change in the failure, no matter what I put in the "-cp" parameter when using the JAR file.
When I run this without using the JAR file, here is the command I execute:
java -cp .;davidp\snmp;filters davidp.snmp.EntMgr
Where this is executed in a directory that has a "filters" and "davidp\snmp" directory. In this case, because the "filters" directory is in my class path - I can dynamically load my class from it using just its simple name (i.e. "TestTrapFilter").
So, is there some bug that precludes the "-cp" parameter from working correctly when the "-jar" parameter is used? Is there some other way to initialize or set up the classloader I'm using, so it can find things outside of the JAR file I'm running from? I would hope that it is possible to get the same behavior from my program, no matter if it is run from a JAR file or not.
Thanks for any assistence!
Dave

These posts are pretty old, but this page came up in a google search while I was having the same problem, so I thought I would throw my own (Later found) solution in.
The -cp and -jar options did not work together for me, but I later learned that they didn't really have to (and you don't have to mess with jar manifest files).
While on the command line, if you want to set a specific class path and also run a jar, all you need to do is add the jar to whatever extra class path you need to use in the -cp <arg>, and then specify which class you want run from inside the jar.
IE:
java -cp <YourSpecialClasspath>: <PathToJar> <ClassToRunInsideOfJar>
in my case it was like:
java -cp /home/user/WebRCP.jar:./StandaloneInstaller.jar InstallLoader
Remember to put a ":" in between the two arguments for the class path (-cp).
Hope this helps someone in the future,
-Josh

Where is the documentation on the Java command line options.

I know you can get them by running java.exe, but does Sun have a web page with a little more detail?

Googling for
java command line options site:java.sun.com
Found this for 1.4. I imagine you should be able to find something similar for 5.0.

Tagging command line programs in subtle?

I'd like to be able to tag command line programs so I can assign them to specific views and gravities within those views.
For example, I'd like to be able to have 'gclacli calm' be recognized by a tag so it appears in my 'agenda' view and assign it a gravity. Is there a way to do this? Right now the best I can do is limit xterm to different views but they still move around when I change views.
Last edited by tinySpark (2012-06-14 18:04:12)

None of these options have worked.
for the user variables, i just create a new one called "Path" and type in my path to java \bin right?
This is quite frustrating. Thanks for the help though!

Creating a command line program reading AEP/AEPX files?

I'm new with After Effects SDK, and I wanted to know if it's possible to use SDK to implement a command line program that gets information such as duration and frame rate in AEP/AEPX files.
aerender, a command line render program provided by After Effects, prints out these information before rendering. But it doesn't seem to be able to print out the information without doing rendering.
I saw a related thread here: http://forums.adobe.com/thread/844341
But what I want is simpler. I don't need to alter the AEP/AEPX files. I just want to obtain the information quickly from an AEP/AEPX file. Is it possible to write such a tool using SDK?
Thanks!

hi eliang.cs!
yes, i'm the same guy who answered on the other thread.
everything the API does, it does through AE as a plug-in.
so if you have AE running (even just the renderer), your project loaded and your plug-in present, you can access all the data you described with no problem, and export it out in whatever way you want. (a plug-in is actually a DLL, so you can do anything you want, even on an OS level)
you can access the data on all elements of the project including comps, layers, footage, render queue, ect...
having said that, you can do all of this using a script instead of a plug-in.
scripts are much easier to build.
perhaps there's even a script out there that does what you're looking for, or something very close that could easily be adjusted.

Importing .eex using Java Command Line on Unix (Licence required?)

Hiall,
We're looking into scripting our deploy process to reduce the amount of manual intervention required. We'll be importing the eex from a Unix box and was wondering what the licencing restrictions are on using the Java Command Line tools.
Do we need a licence for them? Which kind? Desktop or Administrator?
We already have Desktop licences but would rather not have to buy an additional one just for this process.
Thanks for any help you can offer.

Hi
The Java Command Line Utility for the EUL is licensed with the Admin edition so you'll need to purchase at least one Admin license (at current prices these are $5,000 per administrator).
Personally, I've always found scripting to be as much a manual process as entering the Admin tool and using the GUI interface.
Best wishes
Michael

Cope: a command-line program colouriser

cope is a wrapper around various command-line programs that takes their output and adds colours - a sort of ornamental cope, if you will.
It's written in Perl, and requires version >= 5.10, so installation may be a bit complicated if you have to track down the dependencies. It installs several scripts in a directory, each one calling the program it's named after, only highlighting its output using regexes. Then you add this directory to your $PATH, and everything should (hopefully!) be seamless.
Currently it's in release candidate status - I've been using it personally for a few weeks and nothing catastrophic has happened so far, so there's little point me keeping it private.

Fast command-line program which displays connectivity

Hi
I'm looking for a command-line program which can show whether or not my network interface has an IP address or not. It could use "ifconfig" to extract the information, I don't really care, but it has to be *fast* and it cannot require root access.
Thanks

Thanks, but if someone knows some sed/awk magic to get only the interface's IP address, that would be great!
EDIT:
Using the little "sed" I know, this is what I came up with:
ifconfig wlan0 | grep -w inet | sed "s/^\\s*//" | sed "s/^inet addr://" | sed "s/\\s.*//"
EDIT2:
Now I have this reasonable command:
ifconfig wlan0 | grep -w inet | sed "s/.*inet addr:$[^ ]*$.*.*/\1/"

Java command line purge not working after applying MLR 10

Hi Gurus,
After applying the latest patch MLR 10,
java command line purge does not seem to work. I'm using the command
java -ms1024M -mx1024M oracle.tip.repos.purge.PurgeManager purgeRuntime -start 07-APR-2009 -end 22-MAY-2009 Complete
Before running the command i have set the environment using setenv.bat present in ip\install directory.
Below error is observed when trying to purge the messages

Kindly let me know if any post install scripts needs to be run ?
Or is there any thing else i have missed.
Thanks in advance,

Edited by: Cema on May 22, 2009 12:14 PM

Hi Cema,
In MLR 10 these two bugs have been added with others (you can see in patch read me file)-
8432093 - AUTOMATE THE POST PATCH INSTRUCTION SCRIPTS FROM MLR 10 ONWARDS
8339176 - B2B PURGE_RUNTIME PROCEDURE DOES NOT DELETE ALL TIP_WIREMESSAGE_RT RECORDS
Bug 8432093 tells clearly that there is no need of running any post installation script from MLR 10 onwards, so you have not missed anything like post installation script.
Bug 8339176 has addressed the PURGE_RUNTIME functionality for deleting messages. From your earlier posts it seems that you got some errors while applying this patch. Please make sure that patch is successfully installed on your system.
Regards,
Anuj

Uninstalling Command Line Programs

I've searched these forums and the internet for an answer to this, but there doesn't seem to be anything out there, so I hope this will be helpful to others as well.
I have some open source command line programs that I downloaded, compiled, and installed as part of some exercises I was doing in a book on open source GIS (geographic information systems). What I want to know is how do I remove those programs? I can find references for compiling and installing these types of programs all over the internet, but nothing about removing or uninstalling them.
Also, any ideas for good, up-to-date references on learning Unix in Mac OS X would be appreciated too. I'd like to get more into open source GIS, but from the research I've been doing, knowing Unix would help a lot.

What process did you use to compile and install? Was it a configure, make, make install sequence, which is fairly common? If so, go back to the directory where you did that, and try, for example, 'make uninstall'. This might work.
Look for output files from the compile and install process (perhaps config.log) that might tell you where files will be installed. Perhaps in /usr/local?
Is there a README or INSTALL file that came with the source code? Documentation about what was installed where might be there.
If worst comes to worst, and you're really determined, you could repeat the compile and install steps, but with a before and after listing of all the files in your system, and compare the listings. Or use the find command immediately after the reinstall, looking for recently created or changed files (the 'mtime' option or similar).

Java command line in File adapter

Problem executing command line program

Hi I have a tuxedo command line app in Solaris 2.6. I was able to execute the program from unix prompt however when I try to do it from JAVA program, it does not work.
I have to execute from command line as follows
$ud32<SPACE>-U<SPACE>login<nl>
SRVCNM<TAB>CB_EXESUB<nl>
CLFY_SUB<TAB>ExeternalMsg<nl>
EQUIP_ID<TAB>1<nl>
<nl>
during command line execution from second line on you will not get the prompt. After entering a balnk line the program will execute and provide the output.
I was aslo able to execute the program by putting the last 4 lines in a file(say test.bat) and executing by issuing following command at the unix prompt
$ud32 -U sa<test.bat
My java program as follows.
import java.io.*;
public class udexec {
public static void main(String args[]) {
try{
Runtime rt = Runtime.getRuntime();
System.out.println("Before");
Process prcs = rt.exec("ud32 -U sa");
System.out.println("After: " + prcs);
InputStreamReader isr = new InputStreamReader(prcs.getInputStream());
PrintWriter out = new PrintWriter(prcs.getOutputStream());
out.println("SRVCNM CB_EXESUB");
out.println("CLFY_SUB ExternalMsg");
out.println("EQUIPID 1");
out.println("");
int ret = isr.read();
String line;
System.out.println("Before Print");
System.out.println(ret);
catch (Exception e) { System.out.println(e); }
Any help will be greatly appreciated.
Thank You
Raju

Hmm, maybe you should also give additional Excape Characters to the Process (so adding \t where you have written <TAB>, or adding \r to the lines).

Setting column width in a command-line program

Is there a way to send data to the screen in a command-line Java program that will be formatted as a number
of columns with a set column width? I am looking for something similar to the C++ setw() I/O manipulator
used in cout.
Thanks,
Steve

If you go to: http://java.sun.com/docs/books/tutorial/essential/io/writingFiltered.html
it will show you how to subclass a filtered output stream and add your own formatting methods.Then you can chain your new class to System.out
like this:
YourFilteredStream yfs = new YourFilteredStream(System.out); .
Then:
yfs.yourNewMethod(); goes directly to system out in the new format.

Command line program: can it implement keyListener??

Hello,
before I take the trouble to learn keyListener implementation, I am wondering if my program could even implement it. It is just a small game that just plays in the command window. I would like it to respond to the user pressing up, down, left and right keys. Is this possible with a keyListener or is this only possible in a 'windowed' application?
And if you cannot register keys this way from the command line, then how would I make my program interactive. Do you know a link to an API description that explains how to set the program up to give a prompt?
Thank you very much!
-Mike.

guess not...
