Hi all, I am using a WLS and I seems to be getting the following exception randomly while accessing the JSP/ Servlets , There seems to be no reason at all..HAs any one encountered it ? or could it be a bug in WLS ?

Re: DB Access problem
Hi ,
This is a ODBC-JDBC specific error , I had got it once When The value
specified for the argument
ColumnNumber exceeded the maximum number of columns in the result set.
ALSO Some Info :
E10. SQLException: [S1002][Microsoft][ODBC SQL Server Driver] Invalid
Descriptor Index
This exception is usually thrown when retrieving a LONGVARCHAR or
LONGVARBINARY column using the getXXXStream() method (column size >
DefMaxFieldSize of idss.ini). This exception can be avoided by re-ordering
your SELECT statement so that the long column is place at the end of the
select list.
In the two examples below, assume that picture is the only LONGVARBINARY
type column. Then the first SELECT statement can cause this exception, while
the second one works fine:
(X) SELECT name, picture, address FROM employee
SELECT name, address, picture FROM employee
If there are two or more long columns in the same select list, place all of
them at the end of the select list and make sure that your JDBC program
retrieve them in the same order as they appear in the select list.

Re: JSP-Bean question
Hi Mark, One doesnt have to put it in the servlet classpath. I am using JSP use beans heavily and I have placed them in the CLASSPATH(Weblogic CLASSPATH since my App server is WEblogic) and if you could check the generated code I am sure you would find an answer as to why it has to be in a package... For example the bean is instantiated as : utils = (com.etrade.utilities) java.beans.Beans.instantiate(getClass().getClassLoader(), "com.etrade.utilities"); And with out the package name you would have to somehow have a import statement in the generated Java file..

Re: **URGENT***
Manish,
My first advise to you is to Isolate the problem .
Try to write a Simple Java program which runs the unix command..and Make it
to work..
And then try integrating it in to the SErvlet.
I have been doing the same with out any problem ..although it was in
Weblogic App Server
native
Secondly,
Try Studying the servlet demostrated at :
http://www.frontiernet.net/~imaging/FileUploadServlet.html
Thirdly ,
I guess you would have to learn Java programming first before you speed ypur
way in to App Servers..:) J/king

Nagraj

Subject: **URGENT***
Hye all
I am kinda new to Java Programming as such and so to
Jsp and servlet. I have a couple of questions
[1] I get exceptions when i try to run unix command
from my servlet To be precise about the error, this is
what I get on the JSWDK1.0.1 startserver screen:
java.io.IOException: CreateProcess: rlpq
-H101.20.35.78 error=0 at
java.lang.Win32Process.create(Native Method) at
java.lang.Win32Process.(Unknown Source) at
java.lang.Runtime.execInternal(Native Method) at
java.lang.Runtime.exec(Unknown Source) at
java.lang.Runtime.exec(Unknown Source) at
java.lang.Runtime.exec(Unknown Source)
I am performing the following command: rlpq
-H101.20.35.78 which will query the printer
101.20.35.78 and check the status of the printer.
However it works perfectly when I execute in a
stand-alone application and I get the above mentioned
IOException when I execute the same command from the
Servlet.
The code which I try to carry out is..
String[] tokenizedCom = new String[4]; String s;
tokenizedCom[0] = "rlpq"; tokenizedCom[1] =
"-H101.20.35.78"; try { Process myProcess =
Runtime.getRuntime().exec(tokenizedCom);
//DataInputStream in = new DataInputStream(new
//BufferedInputStream(myProcess.getInputStream())); }
catch (IOException e) { e.printStackTrace(); }
I kinda am not sure as to what the problem might be.
If possible, do send in a sample code alias to the
above code.
[2] I want to upload file from the JSP page to my
servlet. One solution I found was to use the oreilley
servlet package. I downloaded that. But I dont know
how to use it. I tried to put that in the import
statement, but not of much help. I even tried to
modify my startserver.bat file on JSWDK1.0.1 by
setting the class path.
Please advice on it.
Thanks a lot
Manish

Re: JSP and Servlet application flow
hi Brad, I had the same confusion , the best approach is: Assume that your web app could have a lot of interfaces The Web Interface is th most obvious thing.. Lets say it could also have a WAP interface... and so on.. Anyway the point I want to drive home is that the Data is the same , but the GUI in a WAP and a Browser is entirely different... Hence we would have to find a mechanism to differentiate the Model from the View. And this is done using a Controller..(could be a servlet, or could be a EJ bean ..which say returns results and the respective JSPs render HTML...) but from a programmers point of view..utlimately even a JSP is converted in to a servlet and hence one might argue that ,why not do some processing in the JSPs too.. But what if the interface changes ??? you might have to touch all the code you had already written (in JSP)? Is it worth ? just because the GIU changed ? Hope this gives you some pointers...
