J2ME-Polish2.0RC4 对doja的支持不是很好。 建议采用 j2mepolish-2.0-Preview.jar。

 

回复：关于需要指定 libraryjars的问题，理解polish原理即可。
见build.xml里的binaryLibraries="${polish.home}/import/midp-2.0.jar"


Hi Robert ,

 

          Thank you .

           

          i think j2mepolish is a very very great software ...  it help me a lot . thank you and your team .

             

 

          i had downloaded j2mepolish-2.0-Preview.jar  ,

          

         it's work well in javac . 

 

          but i meet a error in proguard .

                  

    the prompt :

            [j2mepolish] proguard: Warning: de.enough.polish.event.ThreadedEventListener: can't find superclass or interface              javax.microedition.lcdui.CommandListener
[j2mepolish] proguard: Warning: de.enough.polish.event.ThreadedEventListener: can't find superclass or interface javax.microedition.lcdui.ItemCommandListener

[j2mepolish] proguard: Warning: there were 4 unresolved references to superclasses or interfaces.
[j2mepolish] proguard:          You may need to specify additional library jars (using '-libraryjars'),
[j2mepolish] proguard:          or perhaps the '-dontskipnonpubliclibraryclasses' option.
[j2mepolish] proguard:          If you are sure the mentioned classes are not used anyway,
[j2mepolish] proguard:          you could try your luck using the '-ignorewarnings' option.
[j2mepolish] proguard: Error: Please correct the above warnings first.

 

 

               i had used libraryjars  or ignorewarnings or dontskipnonpubliclibraryclasses just like prompt above ,

                  (

                   <parameter name="ignorewarnings" value="true"/>

                   or  

                   <parameter name="dontskipnonpubliclibraryclasses" value="true" />

                   or 

                   <parameter name="libraryjars" value="${polish.home}/import/cldc-1.0.jar
                                                       ;${polish.home}/import/doja-2.5.jar" />

                   )

              

 

                 but i meet these error prompt:

hi all :

 

 

 

i used doja develop .  

 

i find in /J2ME-Polish2.0RC4/j2mepolish-src/j2me/src/de/enough/polish/io/Serializer.java 

 

 

...

490 line

 

      Externalizable[] externalizables;

 

      //#if polish.midp
        externalizables = new Externalizable[ length ];
      //#endif

 

      //#if polish.JavaSE
        try {
          externalizables = (Externalizable[]) Array.newInstance(Class.forName( cn ), length);
        } catch (Exception e) {
          //#debug error
          System.out.println("Unable to instantiate Serializable /"" + cn + "/"" + e);
          throw new IOException( e.toString() );
        }
      //#endif
     
   Class[] classes = new Class[ Math.min( length, 7 ) ];
   Class currentClass;
   byte idCounter = 0;
   for (int i = 0; i < externalizables.length; i++) {

 

         ...

 

   }

 

...

 

i use doja ,not polish.midp .

 

so variable externalizables might not have been initialized .

 

 

what can i do ?

 

 

 

 

Best Regards,

powinder

I think I have found a bug.

Serializer.java:509: variable externalizables might not have been initialized.

 

    [javac] for (int i = 0; i <                

                   externalizables.length; i++) {
    [javac] ^
    [javac] 1 error
