Setting classpath in Process object

Question

Anybody run into this before?
I am trying to call the OracleXML utility on Windows using the Runtime to get a process object. When I pass my classpath to the Process object, somebody is changing the period in the file name (eg. classes12.zip) to a forward slash (eg. classes12/zip). It doesn't like it if I used the escape character, or any of the other hundred things I tried.
here is my code:
String tmp[] = {"java",
" -classpath ./lib/classes12.zip;./lib/xmlparserv2.jar;./lib/xsu12.jar ",
" OracleXML -getXML -withDTD -rowsetTag ",
" \"RESULTS\" ",
" -conn \"jdbc:oracle:oci8:@xxxxxx\" ",
" -user \"xxxxx/xxxxx\" ",
" \"espread.sql\" ",
" > espread.xml "};
for(int i=0;i<tmp.length; i++) {
System.out.println("Command line array is >" + tmp[i] + "<");
Process p = Runtime.getRuntime().exec(tmp);
int returnVal = p.waitFor();
System.out.println("returnVal from OracleXML = " + returnVal + "<");
java.io.DataInput d = new java.io.DataInputStream(p.getErrorStream());
String line;
while ((line=d.readLine()) != null)
System.out.println(line);
And here is the output showing the substitution:
java.lang.NoClassDefFoundError: -classpath //lib/classes12/zip;//lib/xmlparserv
2/jar;//lib/xsu12/jar
Exception in thread "main"
Any help is greatly appreciated. Thanks in advance.

java.lang.NoClassDefFoundError: -classpath //lib/classes12/zip;//lib/xmlparserv2/jar;//lib/xsu12/jarYeah. Java is doing that. It thinks that whole mess is the name of the class you want to run. In that parameter it allows either . or / to separate the parts of package names, but it prefers / so it does that conversion.
The problem, of course, is that whole mess isn't the name of the class you want to run. I would fix that by not using an array of Strings, but just concatenating all of them into a single String that's going to be your command line.
