  </code></pre>
  
  <p>Please run the above code and generate the document. I have used itext-1.3.jar but same behavior shown with itext-5.3.5.jar.</p>
  
  <p>In the second file named as "text_filled.pdf", I have four pdf cells(fields) in the table. My code is making these editable fields read only but I want scroll bar also(when content exceeds the field limit) as like it is coming for 4th one only, so that user can be able to view whole content without having edit permission.</p>
  
  <p>Could I get read only mode with scroll bar(if content is more than limit of the text field) for each cell of the the table.</p>
  
  <p>I have tried the below code also for making the fields read only.</p>
  
  <pre><code>form.setFieldProperty("text1_1","setfflags",PdfFormField.FF_READ_ONLY , null);
  form.setFieldProperty("text1_2","setfflags",PdfFormField.FF_READ_ONLY , null);
  form.setFieldProperty("text1_3","setfflags",PdfFormField.FF_READ_ONLY, null);
  form.setFieldProperty("text1_4","setfflags",PdfFormField.FF_READ_ONLY , null);
  </code></pre>
  
  <p>If from these codes can't be done then any other possible solution.</p>
