Error numbers

Hi, just a simple question, When an error or exception stack comes, like : at java.lang.Runtime.exec(Runtime.java:551)How can we have access to the details (java:551) ? Is it a line of java.exe or what does it mean? Thanks, Luis.

The information provided includes:

class name: java.lang.Runtime

method name: exec()

source code filename: Runtime.java

source code line number: 551

When you run a java program, there are a few parts to be aware of:

java.exe (a binary program which runs the java interpreter; the interpreter loads java files which have been compiled into classes)

system classes (these classes come with the java system; most of them start with java.lang)

application or applet classes (these are written by the application developer)

If you are using a JDK from Sun, the source files for system classes can be found in a file called src.zip. If the class is named java.lang.Runtime, you should look for a file named java/lang/Runtime.java.

Although it is unlikely that there is a bug in Suns source code, rather the problem is more likely related to somthing in your own code.
