I am basically looking for a small XML template that I can open in Excel with Report look and feel.

An XML file with HTML AND XML tags would be enough.

Please advise

Thanks

I am getting the same for reading a non empty file.

FIle is not empty and fails at the first read..

Thanks

I am getting null for firstLine

String firstLine = inputStream.readLine();

result=-1 for the first time itself..

result = this.readLine(buf, 0, buf.length);

I am trying to add a word document and is causing this error. I tried with a text file also.

Please let me know what I am doing wrong here..

Please see the following code

protected void processRequest() throws IOException { //parse the content type to get the boundary string!. parseBoundary(request.getContentType()); //Boundary validation. if (boundary == null) throw new IOException("Boundary doesn't exist!"); //Max size validation. if (request.getContentLength() > maxSize) throw new IOException( "Input File size is more than " + maxSize + " bytes"); //Read the first line, which is a boundary line. String firstLine = inputStream.readLine(); //check if the first line is boundary string!. if (firstLine == null || !firstLine.startsWith(boundary)) [b]throw new IOException("Invalid input data stream!");[/b] //process rest of the stream; processStream(); } public String readLine() throws IOException { StringBuffer sbuf = new StringBuffer(); int result; String line; //max of 8kb block read before a new line is encountered!. result = this.readLine(buf, 0, buf.length); if (result != -1) { sbuf.append(new String(buf, 0, result, "ISO-8859-1")); } if (sbuf.length() == 0) { return null; } //strip off the trailing /r,/n. if (sbuf.length() > 2) sbuf.setLength(sbuf.length() - 2); // System.out.println("sbuf="+sbuf.toString()); return sbuf.toString(); }


We are trying to add a file as attachment in one of our applications ,,
I am getting invalid input data stream and the same code works fine in another application.

Please advise if anyone has encountered same issue before..

Thanks
Satya

Thanks for reply..

Not knowing EJB much, what kind of NFRs EJB supports..

What are the limitations of using JDBC as data access layer..

The screen will have read/Update records from the DB2 table..

Thanks
Subba

I would like to develop a small size web app(3-5 screens) that needs to access DB2 table in the backend..

What should be the technology used..

JSP/Servlets/java beans
Here how does the database connection happens
What is the architecture diagram look like? like presentation layer/business logic layer/data access layer etc..


JSP/Servlets/EJB - Does it need EJB for a small size app..


Please advise..

PS. I would like to know different combinations of architecture designs for various types of web applications like small, medium and large applications..

can someone guide me thru this.. i am being exposed to web technologies recently and would know JSP/Servlets only..

Presentation Layer - JSP/Servlets
Business Logic Layer - Java Beans
Data Access layer - JDBC


ThankS
