JSP parser internal exception (WebIOException)

[Former Member]

Hello,

On WebAS 640 I get the following exception while starting an ear (please see below).

Obviously one jsp file can not be parsed and there can be numerous reasons for that.

However the only indication of the error is "WebIOException" which tells nothing to me.

Is there any way to get more information about what exactly the jsp parser does not like? So far I looked

through the defualt trace log and all other logs that I

could find. I must be missing something - may be there

is some kind of "verbose output" flag or similar for the

parser.

Any help is highly appreciated.

Regards,

Mikhail

Hi Mikhail,

Yes, there is a property of the Web Container service that forces verbose output of the compiler. This is the CompilerDebuggingInfo property of the Web Container Service on the J2EE Engine. Use the Visual Administrator to set the property to true to get more info about the error.

Hope that helps!

Hi Ivaylo,

Unfortuantely this particular flag was on. But anyway thanks.

Hi Mikhail,

as the errors you pasted in your original post were actually issued as "warnings", then despite them, your application sap.com/VM must have been started. If this is so, try to request the UnpackingView.jsp in the browser. This should issue the verbose output of the compiler in the browser window.

Hi Ivaylo,

I tried your recommendation but the only thing that I get in the browser is

Details: The requested resource ( //servlet/UnpackingView ) is not found

and this is the direct result of the problem with the parser (it did tell me that servlet UnpackingView is not registered as class was not found).

Regards,

Mikhail
