[opencms-dev] How to access own Java Class via JSP in OpenCMS 5 RC2

[ambiesense at gmx.de]

Hello,

thanks for your quick answer :) This sounds good. I have had a look to the
usebean Tag. However this bean need to get access to the OpenCMS instance.
This seems to be a problem. I have used that code before triggered by a content
template. Every time a website, made from this OpenCMS content template, was
accessed. My class overwrites that method:

public byte[] getContent(CmsObject cms, String templateFile, String
elementName, 
                             Hashtable parameters, String templateSelector)
throws CmsException {

so I got access to CmsObject. With this CmsObject I could access i.e. Files
in the VFS or users in OpenCMS. 

How can I do this with the JSP approach?

Any help would be highly appreciated!

Cheers,
Ralf
