OK - so the program compiles now, but it won't run. i can't believe i wasted 4 hours on this. I changed it to "Query.java" and it compiles fine now. Notice that the filename was "Query.Java" with a capital "J" on the extension. The bin directory presents in JDK folder, where javac. still no dice:Ĭ:\labJava>javac -g -classpath C:\j2sdk1.4.2_08\jre\lib\e xt -sourcepath c:\labJaĪrrrghhhhhhhh. Expert Answer PROCESS TO RUN APPLET PROGRAM IN jGRASP After writing the java program in jGRASP, at first save the java file milekm.java in bin directory of java folder through save as option in jGRASP. JavaĪnd finally, tried to separate out classpath and sourcepath. Javac: invalid flag: c:\Documents and Settings\Dave\Desktop\labJ ava\Query. Tried to use quotes to pass full path as arg:Ĭ:\labJava>javac -g "c:\Documents and Settings\Dave\Desktop\labJ ava\Query. This works if i'm in the same path as the java file:Ĭ:\labJava>javac -g C:/Documents and Settings/Dave/Desktop/labJ ava/Query. I have tried a million different combinations. java name or I get the "invalid flag" message. I am using Windows and I have to navigate to the folder and type only the. So am I missing a classpath or someother argument that I need to pass to the compiler (javac)?Īnd yes. getString( 1) " Discnt: " cust.getString(2)) ("Select cname, city, discnt FROM customers") From a command prompt try this: set PATHPATH C:Program Files (x86)Javajdk1.7. ("Could not load the driver") Ĭonnection con=DriverManager.getConne ost:1521:T EST","huds on","hudso n") As far as I can see you have the JRE in your PATH, but not the JDK. So what this leads me to believe, is that there is something inside the compile process that is actually causing the problem because the "Query.java" program makes reference to the JDBC.Ĭlass.forName("oracle.jdbc. ![]() Now, what doesn't make sense to me, is why this DOES work:Ĭ:\Documents and Settings\Dave>javac -g c:\labjava\myfirstjavaprog. Why does it think that the last argument is a flag and not the file name? Javac: invalid flag: c:\labjava\Query.Java However, if I am in another directory, I get an error:Ĭ:\Documents and Settings\Dave>javac -g c:\labjava\Query.Java If I am in DOS and in the SAME directory as the source file, the compile works fine. I have searched all over the web and have found people complaining of this problem, but have never found an actual solution. It looks like the site has some good documentation.I am having a problem compiling and running a program that uses the JDBC. Having never used jgrasp before, I can't give a definitive answer to your questions. This installation help doc seems to talk a bit about setting up the compiler based on specific installations. (You can edit this but be sure not remove anything you don't know about.) d If you need help in setting environment variables then what operating system are you using?ĮDIT: In my shell on Ubuntu 7.10 simply typing $PATH will show defined paths. Yes, to solve the debugging problem it looks like you need to tell it where to find the JDK you have installed. I don't know how to change my PATH or set an environment variable. If anyone could help that'd be wonderful :guitar: Can anyone help? This was my IDE of choice in Windows because of it's simplicity but also because it has a GREAT visual debugger that I find very useful when I'm making trees. I've installed the JRE and JDK (both 1.6) from Synaptic. How can I get jgrasp to debug my programs? You can also set a 'JGRASP_JAVA' environment variable to force jgrasp to use a particular Java version If you have the full JDK installed, you may need to change your PATH to correct this. It appears you are running jgrasp under the JRE (not JDK), or a version of Java that does not support integrated debugging. Secondly, when I try to debug I get this error message and debugging doesn't work: ISO8859-1 (Latin-1) encoding will be used.Ĭharacter display, printing, I/O, and cut-and-paste behavior may not be as expected.ĭoes anyone know what this means or how to fix it? First, I get this message everytime I start jgrasp:ĭefault system character encoding uses multi-bye characters or is not one-to-one.Ĭurrently, jgrasp CSD windows can not handle such encodings.
