Change Default Viewer

[SeanDay]

Hi,

 

I would like to have the option to display each report in only one format (e.g. one report that loads direct to PDF another that loads direct to excel etc..)

 

I think I need to modify the DefaultJasperViewer.jsp file (or maybe create one for excel, one for pdf etc then reference this new file on the customization tab when deploying the report).

 

Can anyone offer some advice on what needs to be changed as so far I have been unsuccesful.

 

Thanks,

 

Sean

Finaly I got around to looking into this again and have found the solution. It was pretty simple I just modified the DefaultJasperViewer.jsp file and removed the part that produces export buttons and html report content. I then manually added the pdf button part and called the javascript function to display the PDF using onload on the PDF icon. I expect there is a better method of doing this but it works fine for what I need.

You could also have created another version of the JSP and modified it to your need. Then on each report unit, you could specify the JSP you wanted to use as the viewer.

Hi Sherman,

 

Thanks for the info, we want most of our reports to go direct to PDF (which is why I replaced the default file as it means we don't have to specify the .jsp for all reports). I have renamed the original DefaultJasperViewer.jsp file so we can still use that for any reports where we require multiple output formats. I will probably also create a specific .jsp that goes direct to excel as well.

 

I am very impressed with JasperReports/JasperServer, I have spent weeks looking at Oracle reports/portal for deployment of reports and was not impressed at all. After spending a few hours (including installing/configuring LDAP etc) I found I could do everything I wanted with JasperServer.

 

Thanks,

 

Sean

Hi,

 

I am having a requirement of using custom JRHtmlExporter i.e i am extending JRHtmlExporter in one of my class and when i call the <customExporter>.exportReport() from DefaultJasperViewer.jsp it is throwing

 

 net.sf.jasperreports.engine.JRException: No input source supplied to the exporter.

 

It is expecting JasperPrint as input and it is not set to the custom class.(Looks like JasperPrint is configured to set to only JRHtmlExporter class.)

 

 

Please let me know is there any configuration changes needs to be done to use custom exporters.

 

Regards

Bhuvi

Resolved the problem,

We can use any custom exporter class, we need to make changes to the JasperViewerTag.java class which is a custom tag lib.
