Some paths, therefore, needto be set. Assuming the J2ME Wireless Toolkit 2.1 has been installed toC:\WTK21 we should set the development platform’s PATH environmentvariable to that directory. On a Windows desktop computer, the path tothe binaries should be set as follows:C:> SET PATH=%PATH%;<install dir>\WTK21\binWe will also need a Java compiler.
We should already have the latestJ2SE SDK installed on the machine, so we can use that compiler. SetPATH as follows:C:> SET PATH=%PATH%;<install dir>\JavaSoft\j2sdk1.4.2\binNow we should be able to use both the compiler and pre-verifier quiteeasily. However, before we proceed we should also add a couple ofenvironment variables to make MIDlet creation a little easier. We need todirect the commands towards the MIDP API and the other J2ME classes.Therefore we should set the following variables:C:> SET J2MEHOME=<install dir>\WTK21C:> SET MIDPAPI=%J2MEHOME%\lib\midpapi20.jarC:> SET J2MECLASSPATH=%J2MEHOME%\wtklib\kenv.zip;%J2MEHOME%\wtklib\kvem.jar;%J2MEHOME%\wtklib\lime.jar;%J2MEHOME%\lib\cldcapi10.jarProgramming Java 2 Micro Edition on Symbian OS: A developer’s guide to MIDP 2.0.
Martin de Jode 2004 Symbian Ltd ISBN: 0-470-09223-8438USING THE WIRELESS TOOLKIT TOOLS AT THE COMMAND LINENow that some handy variables have been set, we can try to createa MIDlet suite. Once the classes have been written, they need to becompiled. The following command should be used to compile all theclasses in the current directory and then put them in a previously createddirectory, tmpclasses. Note that we have specified the classpath of theMIDP API to make sure the compiler knows to compile against the CLDCand MIDP classes, otherwise the classes may be compiled against theJ2SE SDK.C:\WTK20\apps\Example\src>javac -d tmpclasses -bootclasspath %MIDPAPI%-classpath %J2MECLASSPATH% *.javaOnce this has been completed, all the compiled class files can beseen in the tmpclasses directory.
We should now pre-verify them. Bytyping the word preverify at the command line the following helpinformation appears showing the options available.Usage: preverify [options] classnames|dirnames ...where options include:-classpath<directories separated by ';'> Directories in which to lookfor classes-d <directory> Directory in which output is written (default is./output/)-cldcChecks for existence of language features prohibited byCLDC (native methods, floating point and finalizers)-nofinalizeNo finalizers allowed-nonativeNo native methods allowed-nofpNo floating point operations allowed@<filename>Read command line arguments from a text file Command linearguments must all be on a single line; directory names must be enclosed indouble quotes(")There are two options of interest to us here.
The -classpath option,which will specify which target API should be verified against, and the -doption, which specifies the output directory for these verified files. Thefollowing command should be issued in the current directory:C:\WTK20\apps\Example\src > preverify -classpath %MIDPAPI%;tmpclasses-d classes tmpclassesThe pre-verified files will now be in the classes directory. Thesefiles are ready for packaging into a MIDlet suite.
For this we use the jarcommand:C:\WTK20\apps\Example\src> jar -cvf MyMidlet.jar classes/*In this case we have asked the jar command to create a JAR filecalled MyMidlet.jar from all the files stored in the directory structureunder classes/.Appendix 4Developer Resources and BibliographyDownload code for this book fromwww.symbian.com/books/pjso/pjso-source.htmlSymbianCorporateDeveloperwww.symbian.comwww.symbiandevnet.comSymbian LicenseesArimaBenQFujitsuLenovoLGElectronicsMotorolaNokiaPanasonicPsionSamsungSanyoSendoSiemensSony Ericssonwww.arima.com.twwww.benq.comwww.fujitsu.comwww.legendgrp.comwww.lge.comwww.motorola.comwww.nokia.comwww.panasonic.comwww.psion.comwww.samsung.comwww.sanyo.comwww.sendo.comwww.siemens.comwww.sonyericsson.comOnline Developer ResourcesMotorolahttp://idenphones.motorola.com/iden/developer/developer home.jspNokiawww.forum.nokia.comProgramming Java 2 Micro Edition on Symbian OS: A developer’s guide to MIDP 2.0.
