It seems that you are using Command object from the lcdui lib. Check your class imports and add the Commandobject from the LWUIT lib.

Got the answer ... It was unicode mistake . I have copy n pasted the code for local.js from one of my coworker's pdf file. So when I pasted that code in my local.js "-" was replaced with some unicode http://www.fileformat.info/info/unicode/char/00AD/index.htm .. and that was causing this issue..
I have VB project, which is compiling/building perfectly using vb6 IDE in XP mode.
My objective is to automate the deployment process, so am trying to build this project in command line using VBC.
But while compiling vb project in window 7 using VBC.exe and cmd its throwing following error/exception.
Example:
error: BC30203: Identifier expected.
error: BC30481:'class' statement must end with matching end class.
error: BC30617:'Module' statement can occur only at file or namespace level.
Does anybody have any suggestion ideas what am missing here.
Thanks in advance.
I've just started to learn JFlex. I am studying one of the official Jflex examples, which is a scanner for the Java language. In the Readme file it says:
The scanner (without parser attached) can be test with:
java TestLexer <inputfiles>
But when I tried this in cmd, I got an error message instead, saying 'Could not find or load main class TestLexer'.Does anyone know why? Thank you in advance.
To test the lexer for Java, JFlex has a depency to the CUP parser generator, did you installed it?
Then there is several commands to make before being able to run the lexer:
jflex unicode.flex
jflex java.flex
java java_cup.Main -interface < java12.cup
javac JavaParser.java TestLexer.java
For the third command, you need to have the java-cup-11a.jar somewhere in your classpath.
Only then you would be able to test the parser:
java JavaParser <inputfiles>
or the scanner:
java TestLexer <inputfiles>
I copied the templates from here to add scaffolding with Twitter Bootstrap thanks to the twitter-bootstrap:2.3.2 plugin.
generates-all works with no errors and creates everything with the look of Twitter Bootstrap.
But I get the next (false?) error:
- Groovy:unexpected token: < # line 1, column 1.
At the next line of code:
<%=packageName ? "package ${packageName}\n\n" : ''%>import org.springframework.dao.DataIntegrityViolationException
This is the Eclipse structure:
If it is just a mistake of eclipse, how could I tell it to ignore it?
My solution so far is to comment out all the Controller.groovy class. The issue is that if I want to use "grails generate-all domain_class" I should remember remuving the comment previously.
