Greetings,

I've been searching everywhere for an editor to use with Java. I'm new to programming and I do NOT want to spend an eternity learning the software I use to write software ;)

I started using TextPad because it was recommended in the book I am using, and it was nice, but I love Programmers Notepad! Your website, the forum, the software, the icons, everything is minimalistic and I love it! Clean, usable, and powerful...perfect.

I just need two little buttons to make it 100%. I need compile and run buttons that will open the javac and java commands in the command window on Windows XP so that I can test my Java programms from the promt without having to leave Programmers Notepad to do it. I noticed there is a way to add user tools, but I am not sure how to do this. Anyone have it set up this way that would be willing to share the steps with me?

Thanks,

Aaron Jackson

I figured out the compile command, but I still haven't figured out how to set a run command because it must act on the .class file created by the compiler and not on the file being edited by Programmers Notepad. Any idea how I can make this work? Thanks again...

Just go to the options, click on tools, go down to java, click add, and put in the following.

For command put: java
For folder put: %d
For options put: %n.class

As long as you run the tool while working on the driver file then it will run it fine. The %n is the file with no extension.

If you want it to run on the command line then go to the output tab and uncheck "capture output" and change the original values to the following:
cmd
%d
/K "java %n.class"

Hope that helps/works for you! ;)

Thanks a million! I ended up having to leave the .class off because it confused java, but it works! I actually had to add two commands, one for running java apps that don't require input and one that opens the command window for apps that require input. There doesn't appear to be a way to input data and it breaks the output window when my app starts asking for input.

Thanks again...this is exactly what I've been looking for!

Are there any banners or anything for Programmers Notepad evangelism?

I'll try making one, <i>But don't hold it</i>. I love PN so much too.

Yeah, forgot that javac takes the full name with .java and the vm just takes the class name without .class. Shoulda remembered, but happy it worked!

Hmmm...I still get (when using a file called "Ex1.java")
code
> "javac" Ex1.java

> Failed to create process: The system cannot find the file specified.

> Process Exit Code: 0
> Time Taken: 00:00
code

when I use
command: javac
folder: %d
paramaters: %f

Don't we need to tell the command prompt where java.exe is? I don't think it has an environment variable.

(My installation of Java does work when I use the command line.)

In your command box use the full path to javac, you can browse for it.

Well, that helped :-)
I'm not getting an error anymore, but PNotepad isn't capturing the console output correctly, even though I have capture output selected.

I've just added a tool to do this and it seems to work fine for me with a very simple java test program. Could you please send your usertools.xml file to ss at pnotepad dot org and I'll have a look and see if there's any difference?

I did send usertools.xml, but there has been no response email.
My file is actually small enough to paste in here:
(I added extra linebreaks so it would be easier to read, which XML allows anyway...)
<schemetools>
<scheme name="java">
<tool
command="C:\Program Files\Java\jdk1.5.0_06\bin\javac.exe"
flags="33"
folder="%d"
index="0"
name="Java Compiler"
params="%f"
parsepattern=""
shortcut="0" />
</scheme>
</schemetools>

Ummm, is this tread dead? I apologize for rushing, but I am in a Java class this quarter and it would be extremely helpful for both me and all the other students if we could get this solved.

It has occurred to me that set classpath= is what we normally use when using the command prompt (in Windows at least), so I am wondering if that needs to be addressed when making PNotepad call and run the complier correctly...hmm, I'll take another look at this soon. I seem to have failed to consider the fact that I was merely compiling, not running the code. Nevertheless, I am not getting any confirmation in the PNotepad output frame for successful compiling either.

Maybe this can help. The next solution adds these java tools to PN:

==javac current .java file
==javac -g current .java file
==debug class of current .java file
==debug jar containing class of current .java file [PN will ask the name of jar file]
==debug applet from current .java file [see below running applets in java files]
==run jar containing class of current .java
[PN will ask the name of jar file]
==run class of current .java file
==run applet in current .java file [see below running applets in java files]
==see java docs and tutorials.

**Note: for running applets from java files, write this code at the top of your java file:

/*
<HTML>
<BODY>
<APPLET CODE="YourApplet.class" ARCHIVE="YourFile.jar" WIDTH=100 HEIGHT=300></APPLET>
</BODY>
</HTML>
*/

this allows you to run appletviewer YourApplet.java and launch YourApplet.class in YourFile.jar without html files.

Also notice jar files aren't created with tools above - for this kind of processes I'd recommend write a make.bat file.

OK, here is the solution:
Backup and then open your UserTools.xml file with notepad (this file is in documents and settings\your username\program data\echo software\PN2\)
Then look for the tag block <scheme name="java> </scheme>and replace it by:

<scheme name="java">
<tool command="C:\Archivos de programa\Java\bin\javac.exe" flags="105" folder="%d" index="0" name="compile" params="%f" parsepattern="%f:%l:" shortcut="0" />
<tool command="C:\Archivos de programa\Java\bin\javac.exe" flags="105" folder="%d" index="1" name="compile -debug" params="-g %f" parsepattern="%f:%l:" shortcut="0" />
<tool command="C:\Archivos de programa\Java\bin\jdb.exe" flags="40" folder="%d" index="2" name="debug class" params="%n" parsepattern="" shortcut="0" />
<tool command="C:\Archivos de programa\Java\bin\jdb.exe" flags="40" folder="%d" index="3" name="debug jar" params="-sourcepath .; -classpath %?.jar %n" parsepattern="" shortcut="0" />
<tool command="C:\Archivos de programa\Java\bin\appletviewer.exe" flags="40" folder="%d" index="4" name="debug applet" params="-debug %f" parsepattern="" shortcut="0" />
<tool command="C:\Archivos de programa\Java\bin\javaw.exe" flags="41" folder="%d" index="5" name="run jar" params="-classpath %?.jar %n" parsepattern="" shortcut="0" />
<tool command="C:\Archivos de programa\Java\bin\javaw.exe" flags="41" folder="%f" index="6" name="run class" params="%n" parsepattern="" shortcut="0" />
<tool command="C:\Archivos de programa\Java\bin\appletviewer.exe" flags="41" folder="%d" index="7" name="run applet" params="%f" parsepattern="" shortcut="0" />
<tool command="c:\windows\explorer.exe" flags="40" folder="" index="8" name="java tutorial" params="C:\Archivos de programa\Java\tutorial\index.html" parsepattern="" shortcut="0" />
<tool command="c:\windows\explorer.exe" flags="40" folder="" index="9" name="java API" params="C:\Archivos de programa\Java\docs\api\index.html" parsepattern="" shortcut="0" />
</scheme>

Note: verify your java path. Mine is "C:\Archivos de programa\Java\bin"
If you don't have still the block <schemer name="java></scheme> just insert the code above inside <schemetools></schemetools>

No environment vars needed. And also the javac tools are configured to parse output, so you can easily find errors by clicking on them!.

I help it is usefull.

The only difference between my javac which seemed to work fine and the one that you're trying to run is that you're using the per-editor output window. Perhaps you could try using the main output window and see if this fixes the problem?

If you need a classpath set up then you may need to set that in your environment variables outside PN.

That's a wonderful Java tools collection here with PN :) but I need some help in inputting data from a console through the runtime of the Java program (NOT as Variable Arguments) let me give an example as Java code:

///////////////////////////////////////
/* MyProg.java */

public class MyProg{
public static void main(String [] args){

BufferedReader reader= new BufferedReader(new InputStreamReader(System.in));
String name = "";
int counter = 0;

//gets the users' name
try{
System.out.println("Enter name: ");
name = reader.readLine();
}catch(Exception e){
System.out.println("Invalid input");
System.exit(0);
}
}
}

/////////////////////////////////////////

after compiling this code as follows:
javac MyProg.java
then running the sw as follows:
java MyProg
the programs asks in the output screen as follows:
Enter name:

The question now is how to enter the name through the output screen not through the console cmd?

Sorry for this long question but frankly it made me suffer as a new user to PN

Waiting for your reply

Currently the output window is not interactive - you can't do what you're wanting to do directly inside PN. Sorry! Instead you should turn off capture output and run your program externally.
