com.itextpdf.text.Document : This is the most important class in iText library and represent PDF document instance. If you need to generate a PDF document from scratch, you will use the Document class. First you must create a Document instance. Then you must open it. public Serializable save(Object object) throws HibernateException public Serializable save(String entityName,Object object) throws HibernateException Both save() methods take a transient object reference (which must not be null) as an argument. Hibernate expects to find a mapping (either annotations or an XML mapping) for the transient object s class Hibernate cannot persist arbitrary unmapped objects. If you have mapped multiple entities to a Java class, you can specify which entity you are saving (Hibernate wouldn't know from just the Java class name) with the entityName argument. The save() methods all create a new org.hibernate.event.SaveOrUpdateEvent event. We discuss events in more detail in Appendix A, although you do not have to worry about these implementation details to use Hibernate effectively. At its simplest, we create a new object in Java, set a few of its properties, and then save it through the session, as follows: Supplier superCorp = new Supplier(); superCorp.setName("SuperCorp"); session.save(superCorp); It is not appropriate to save an object that has already been persisted. Equally, it is not appropriate to update a transient object. If it is impossible or inconvenient to determine the state of the object from your application code, you may use the saveOrUpdate() method. Hibernate uses the identifier of the object to determine whether to insert a new row into the database or update an existing row. The method signature is as follows: public void saveOrUpdate(Object object) throws HibernateException Once an object is in a persistent state, Hibernate manages updates to the database itself as you change the fields and properties of the object. how to write pdf file in java: How to Read and Write PDF Files in Java - Gnostice how to write pdf file in java using itext Convert Byte Array to PDF in java - My Java Works

No surprises here; you re seeing the same data you browsed through in the Document Viewer. Naturally, you re not always interested in all the data, and XQuery supports the use of predicates, conditions, and similar constructs to refine your queries. The equivalent of selecting columns in SQL is to use the / character and the names of the element you want to see. So if you re interested only in the names of your customers, extend the XQuery as follows: Xquery declare default element namespace "http://posample.org"; for $x in db2-fn:xmlcolumn('FUZZY.CUSTOMER.INFO')/customerinfo/name return $x | Here, you re instructing the XQuery processor to walk through the document and pick out the <name> child elements of the <customerinfo> top-level elements. The results look like this (with a little touchup of the formatting): 1 ----------------------------------------------------------------------------------<name>Kathy Smith</name> <name>Kathy Smith</name> <name>Jim Noodle</name> <name>Robert Shoemaker</name> <name>Matt Foreman</name> <name>Larry Menard</name> 6 record(s) selected. You might immediately think that the logical extension is to select multiple columns. That s where the analogy with SQL stops or takes a little detour because you re not dealing with tabular data, but with a tree. To fetch elements that are peers, or from different branches of the XML document, use the let clause of the F-L-W-O-R syntax: Xquery declare default element namespace "http://posample.org"; for $x in db2-fn:xmlcolumn('FUZZY.CUSTOMER.INFO')/customerinfo let $cname := xs:string($x/name) let $cprovince := xs:string($x/addr/prov-state) return ($cname, $cprovince) | The xs:string notation is similar to data type casting in regular SQL you re indicating that the data to be retrieved should be treated as a string. The let clause can leverage the alias that you declare for the matching elements in the for clause, saving you from having to type how to open pdf file in browser using servlet: display pdf report directly in jsp - Pentaho Forums write image to pdf in java How To Set PDF File Display In Servlet - JavaBeat
