How to pass String[] from .java to .jsp, java, jsp, string, service, request.getattribute, final solution, jspportlet.java, testing, liferay testing

Nicolas Mugnier	:	Hello,
		I don't know if i post in the good section...
		Could you tell me how can I pass a String[] from my .java to my .jsp ?
		I tried to do :
		.java
		.jsp
		but it doesn't work.
		I tried with for loop but it doesn't work...
		Could you help me ?
		Thanks, Best
		Nicolas
Mazhar Anwar	:	You can set your object in java as request attribute as
		and in jsp
		HTH, Regards, Mazhar
Nicolas Mugnier	:	Thanks for your answer.
		But I think I must be mistaken. I wrote :
		in .java :
		and in .jsp :
		I've got an exception at red line.
		Where am I wrong ?
		Thanks Best
		Nicolas
Mazhar Anwar	:	It seems correct only. Can you check array length in both, in java as well as jsp. One more option is you can initialize the array length in jsp as
		String[] allServiceNames;
		if(request.getAttribute("allServiceNames")!= null)
		allServiceNames = new String[(String[])request.getAttribute("allServiceNames").length];
Nicolas Mugnier	:	I checked array length. Array lengths are correct but :
		When I check length before getParameterValues it's ok (red line)
		However, when i check length after getParameterValues, it crashes : nullpointerexception.
		I think there is a problem in my .java, when i'm passing my String[] :
		Thanks
Nicolas Mugnier	:	It's working fine.
		I post final solution, maybe it will help other developpers :
		in .java:
		in .jsp:
		Thanks Mazhar for your help ;)
		Regards

Babu Janarthanan	:	Hi Pankaj,
		place this code in your java class.
		request.setAttribute("testing","testvalue");
		in jsp.
		String testValue = (String)request.getAttribute("testing");
		if(testValue!=null) { System.out.println(" Test Value.... "+testValue); }
		Thx, Babu
Mazhar Anwar	:	Hi Pankaj,
		You need to set parameters in doView(RenderRequest request, RenderResponse response) method of JSPPortlet.java,
		and if you are using action request then in ProcessAction method of JSPPortlet.java.
