Re: java.lang.NoClassDefFoundError in ejb?

    I'm fairly new to ejb's so this might have an obvious solution
that I'm not aware of. The following snippet of code compiles and
runs just fine (with all necessary packages included) if not run as
part of an ejb. However, if I make this an ejb, deploy it, and then
try to call it, I get a java.lang.NoClassDefFoundError on line 164.
The code and stack trace are listed below. Any ideas?
    By the way, I'm using Weblogic 8.1.

///////////////////////////////////////////////////////////////////////////?///
if (aoInput.getClass() == AttorneySummaryInput.class) {
  // This is line 164 (see call stack)

    loLAISummaryOutput = new AttorneySummaryOutput();
    try {
       GetAttorneysCmd loCmd = new GetAttorneysCmd();
       loLAISummaryOutput = (AttorneySummaryOutput)loCmd.execute((LAISummaryInput)aoInput);
    } catch (Exception ex) {
       loLAISummaryOutput.setError(ex.getMessage());
       loLAISummaryOutput.setCount( -1);
    }
}
