Is it possible to save Jasperprint object

2006-03-10 05:44

Hi all,

 

Is it possible if we can save the jasperprint object to file and saved to database? So if we execute a report with the same parameter, we don't need querying anymore. We just only call the old jasperprint and show the data.

Pls help me..

Thx a lot..

You can definately store a jasperprint object.

 

However, you might have noticed some posts here on the issues of serial UID. Anyways, if you upgrade a version of jasper the old reports will throw an error when you read them out.

 

The only way currently to get around this is to save(export) the jasper print object as xml. The store that into the DB.

 

Look into the JRXmlExporter and JRPrintXmlLoader.

 

Hope this helps.

yes that is what i do, well actually i store the source & the compiled report on the server.

 

if the compiled report matches the current jasper library version, then it uses the compiled version, if it does not match I use the source report then re-compile.

 

you will still need to query the data
