File name mystery - works in BeanShell - but not in plain java

Question

I have added a step in a KM with the following:
<%
import java.io.*;
try
FileWriter tempFile = new FileWriter("newSourceTableList_"+odiRef.getSession("SESS_NO")+".txt");
tempFile.write(newSourceTableList);
tempFile.close();
catch (Exception e)
out.println(e.toString());
%>
When it executes it gets the following error: "java.io.FileNotFoundException: newSourceTableList_2778001.txt (The filename, directory name, or volume label syntax is incorrect) "
If I put the exact same code in a step using Java Beanshell technology - the file is written correctly. Is the working directory set differently for the different technologies?
Why does this not work in plain Java technology??

Answer 1

Sorry for the delay - other projects stole my time.
I tried this and it produced a parsing error when executed: (looks like the parser is doubling the backslashes - the KM only has one - maybe causing more problems?)
BeanShell script error: Sourced file: inline evaluation of: `` import java.io.*; out.println("Checkpoint 2 [" + newSourceTableList + "]"); tr . . . '' Token Parsing Error: Lexical error at line 7, column 12. Encountered: "\\" (92), after : "": <at unknown location>
BSF info: get computed source table names at line: 0 column: columnNo
import java.io.*;
out.println("Checkpoint 2 [" + newSourceTableList + "]");
try
FileReader(\\u0022newSourceTableList_\\u0022odiRef.getSession("SESS_NO")\\u0022.txt\\u0022); FileReader.read(newSourceTableList);
FileReader.close();
out.println("Checkpoint 3 [" + newSourceTableList + "]");
File tempFileObj = new File("newSourceTableList_"+odiRef.getSession("SESS_NO")+".txt");
tempFileObj.delete();
catch (Exception e)
out.println(e.toString());
