sending a variable set in java tag library definition to jsp file

[shriya hegde]

Hi All,

I am working on some enhancement on application which was written 15 yrs back. I have a requirement. The flow is as below

In a jsp file one selection dropdown exists and a body.
Selection dropdown is written as custom tag library and is included in jsp file eg tag.tld whose code exists in tag.java
code for other parts of jsp are written in that *.jsp file itself. eg test.jsp

i.e test.jsp calls tag.tld to include selection dropdown

I now want a hashmap created in tag.java to be available in jsp file and I want to use it in one of the javascript function available in same jsp file for validation

How can I achieve this

Making it available to the JSP is as easy as creating a scoped variable.

JavaScript executes on the client and has no access to server-side data. You'll need to use the JSP to create JavaScript constructs that contain the data.
