Unclosed character class near index 0

Question

Hi foks,
I am tryin to remove few characters from a string with the help of replaceAll ( String, String ) method.
But at the first replacement itself it gives error "Unclosed character class near index 0".
what does this error mean? I dont have any ' [ ' character in that string. It used to be there, but now I am removing all the occuring of the ' [ ' char right at the creation of string.
Thanks in advance.

Hi,
Here is the code.
[ CODE ]
public static String extract(String para)
String definition = para.substring(para.indexOf("<ol>"),para.indexOf("</ol>"));
StringBuffer meanings=new StringBuffer();
StringReader reader = new StringReader(definition);
StringWriter writer = new StringWriter();
boolean append=false;
int ch;
try
while((ch=reader.read()) != -1)
if(ch=='<' || ch=='&')
append = false;
continue;
else if(ch=='>' || ch==';')
append = true;
continue;
if(append && ch != '[' && ch != ']')
writer.write(ch);
catch(IOException e)
System.out.println("IOException:"+e.getMessage());
catch(Exception e)
System.out.println("IOException:"+e.getMessage());
meanings=writer.getBuffer();
String temp = meanings.toString();
System.out.println("temp:"+temp);
temp=temp.replaceAll("["," ");
System.out.println("temp:"+temp);
temp=temp.replaceAll(" "," ");
System.out.println("temp:"+temp);
return temp;
