Question

JSTL expression evaluation from a string

Answer 1

+1 A:

I'm not sure I understood it correctly, but I think you just need this expression:

${model[fieldPath]}

In EL dot operator and [] subscription are basically the same: different syntax, but the same access.

Thanks for your response. But in our case "fieldPath" value was pointing to a complex structure like "matrixAssumptions[assumptionId].data[rowName].data[matrixColumns[0]].percentage".When I try to use [] instead of EL dot, it is not able to find such field in the object and throws exception.

@Venkatesh: What exception specifically? You should be able to put the whole expression into the brackets in `${model[...]}` if it gives a valid property name (valid for `${model}`, that is).
