Description

Gets the classpath of the current Java VM.

Syntax

javavm.getJavaClasspath( )

1	javavm.getJavaClasspath( )

Return value

String

Examples

This example shows how to use GetJavaClasspath to get the
classpath when the JVM is started and write it to a log file:

// instance variables:
// JavaVM i_jvm
// boolean i_jvm_started = false
// string is_classes

//Start JavaVM and Prepare to Connect to EJB server
string classpath
Integer li_ret

//create JAVAVM
if ib_jvm_started = false then
   i_jvm = create javavm

  classpath = is_classes
  li_ret = i_jvm.createJavaVM(classpath, true)
  if li_ret = -1 then
    MessageBox("Error", "Failed to load JavaVM")
  end if
  if li_ret = -2 then
    MessageBox("Error", "Failed to load EJBLocator")
  end if

  ib_jvm_started = true

  integer li_FileNum
  string ls_classpath, ls_string

  li_FileNum = FileOpen("C:	empclasspath.log", &amp;
     LineMode!, Write!, LockWrite!, Append!)
  ls_classpath = i_jvm.getjavaclasspath()
  ls_string = String(Today()) + " " + String(Now())
  ls_string += ": ~r~n" + ls_classpath + "~r~n"
  
  FileWrite(li_FileNum, ls_string)
  FileClose(li_filenum)
end if

// instance variables:

// JavaVM i_jvm

// boolean i_jvm_started = false

// string is_classes

//Start JavaVM and Prepare to Connect to EJB server

string classpath

Integer li_ret

//create JAVAVM

if ib_jvm_started = false then

i_jvm = create javavm

classpath = is_classes

li_ret = i_jvm.createJavaVM(classpath, true)

if li_ret = -1 then

MessageBox("Error", "Failed to load JavaVM")

end if

if li_ret = -2 then

MessageBox("Error", "Failed to load EJBLocator")

end if

ib_jvm_started = true

integer li_FileNum

string ls_classpath, ls_string

li_FileNum = FileOpen("C: empclasspath.log", &

LineMode!, Write!, LockWrite!, Append!)

ls_classpath = i_jvm.getjavaclasspath()

ls_string = String(Today()) + " " + String(Now())

ls_string += ": ~r~n" + ls_classpath + "~r~n"

FileWrite(li_FileNum, ls_string)

FileClose(li_filenum)

end if
