Message:
printStackTrace
Posted by lucho on December 03, 2001 at 5:48 AM
Hi!
I wanna catch an SQLException and print its stack trace in a JTextArea rather than the standart output. The method Throwable.getMessage() do not give enough details. I need a procedure like this:
private String getExceptionStack(Throwable t)
I try to redirect the stream using the method Throwable.printStackTrace(PrintStream stream)
Here is my method: private String getExceptionStack(Throwable exc)
{
try
{
String result=null;
PipedInputStream pInput=new PipedInputStream();
PipedOutputStream pOutput=new PipedOutputStream(pInput);
PrintStream pw=new PrintStream(pOutput);
exc.printStackTrace(pw);
byte b[]=new byte[pInput.available()];
pInput.read(b,0,pInput.available());
result=new String(b);
return result;
}
catch (IOException e)
{
return "IOException occured while trying to extract stack!";
}
} Sometimes it works but sometimes exc.printStackTrace(pw); blocks and won't return!!! And my thread is deadlocked :( I wanna know why and I'm interested in another implementation of this problem. Tx!
