Talend 5.6 and jdk1.5 -> The method isEmpty() is undefined for String

[Anonymous]

I must use the jdk 1.5 but it seems not working with talend 5.6.
I have changed Preferences in Talend Open Studio :

java -> installed JREs

and 

Compiler -> Compiler compliance setttings

But I have then the error : The method isEmpty() is undefined for the type String 
isEmpty is defined in jdk 1.6
I try to run Open studio with the Option "-vm D:\java\jdk1.5.0_10\bin" without success.

I don't believe Talend supports Java 5 for v5.6. The "isEmpty()" method for Strings was added in Java 6.

Hi,
Talend don't support for JDK 1.5.
Please take a look at document about:TalendHelpCenter:Compatible Platforms and Java environments.
