add classes

[matnace]

How do you add the classes so the import statment recognizes them. I'm building wireless apps targeting the J2ME runtime. I have it installed but these import statements are erroring out.


import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

is there some sort of preference that I need to add? I running netbeans 3.5.1 for the IDE

Try downloading the J2ME toolkit from Sun... compiles projects for me OK. http://java.sun.com/products/j2mewtoolkit/download.html

In addition to that you need to set the bootstrap classes with the -bootstrap compiler option.

CornedBee might be right. The primordial or bootstrap classloader will search in the locations(directories and zip/jar files) specified in the sun.boot.class.path system property.

As far an i understand it the java core classes are loaded by the primordial classloader and application specific classes are loaded by the system (or application) classloader.

After dowloading the JCE i remember having to add locations to my classpath but no bootstrapping was done.

So how do I set up this -boostrapper and classpath properties

[CornedBee]

javac -bootclasspath "path\to\j2me\bootstrap.jar" -classpath"path\to\classes;path\to\other\classes.jar" mymicroapp.java

etc...

Actually I used a bunch of batch files and installed them as a tool in EditPlus, worked really well, except that I manually had to edit one file every time...

builmeapp.bat

javacme.bat

prever.bat

@d:\work\java2\wtk\bin\preverify.exe -d classes -cldc -classpath d:\work\java2\wtk\lib\midpapi.zip tmpclasses

jarme.bat

@jar cfm %1.jar %1.manifest.txt -C classes . -C res .
