Classpath for java packages

Question

I am trying to execute java files which are present in C:\dss\dss_tests\src\src_devTests\com\ti\debug\engine\scripting folder. When I am executing it its shows lot of error because the class path for packages are not set. So, I set the class path C:\dss\dss_tests\lib\com\ti\debug\engine\scripting because all the class files are present in this location. And some of the jar files contain packages and I have given the path where all jar files are present. Still some errors occur due to some unknown packages. I tried to search in all the folders but I couldn?t find that packages.
the errors i am getting is
C:\dss\dss_tests\src\src_devTests\com\ti\debug\engine\scripting>javac Argc.java

please help to execute this java file
Please help me on this

Hi kav,
So, I set the class path C:\dss\dss_tests\lib\com\ti\debug\engine\scripting because all the class files are present in this location.How do you set that? You have to set the classpath jar by jar, here is an example of a classpath:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
     <classpathentry kind="src" path="src"/>
     <classpathentry exported="true" kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
     <classpathentry kind="lib" path="C:/control/drivers/terajdbc4.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/activation.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/commons-net-1.4.1.jar" sourcepath="lib/commons-net-1.4.1"/>
     <classpathentry kind="lib" path="C:/control/drivers/db2java.zip"/>
     <classpathentry kind="lib" path="C:/control/drivers/jakarta-oro-2.0.8.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/jakarta-regexp-1.5.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/log4j-1.2.15.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/mail.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/sqljdbc.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/tdgssconfig.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/tdgssjava.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/db2jcc.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/db2jcc_license_cisuz.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/db2jcc_license_cu.jar"/>
     <classpathentry kind="lib" path="C:/control/drivers/charsets.jar"/>
     <classpathentry kind="output" path="bin"/>
</classpath>I hope it helped!
