Problem with redirecting cat command output to a file

[Pratiksha Powar]

Problem 1:
--------
Following is the code (in a shell script)which redirects find command output
to a file called "src". But this command generates a file called "src?"
instead.

SOURCE_PATH="src"
rm -f $SOURCE_PATH
#Getting all OPS src files
find ../../com/onmobile/noc/common -name *.java > src

Problem 2:
---------
Later I need to read the src file.
To circumvent Problem 1, if I use the below code :

SOURCE="$SOURCE_PATH?"
$JAVA_HOME/bin/javac -classpath $CLASSPATH -d $OUTPUT_PATH -sourcepath < cat
$SOURCE

I receive following error:
cat: No such file or directory

Could this problem be solved?
I'm using CentOS 10.0, Shell: Bash

Thanks,
