Extended attributes in to an array

There is an XML file containing extended attibute name value pairs.
I want to extract all the attibutes in to an array and assign them to a file in teamsite using the following command.

destSimpleFile.setExtendedAttributes(cseaCSExtAttrA);

is this the correct syntax to do so. I get a warning message on assigning value to the array. Warning given below the assignment.

Appreciate if anybody has a way around to do this job.

=================XML File==================
value of attr 1001

=======CODE to Extract and set ext attributes=======
CSExtendedAttribute[] cseaCSExtAttrA = null;

//get the employee element
Element attrElement = (Element)nl.item(i);
String attrName = attrElement.getAttribute("name");
String attrVal = getTextValue(attrElement);

System.out.println("Attr Name " + i + " :" + attrName + "===Attr Value:" + attrVal);

//=============================================================
cseaCSExtAttrA[0].setName(attrName);

// The above line shows a warning ===> Null pointer access; The variable cseaCSExtAttrA can only be null at this location.

cseaCSExtAttrA[0].setValue(attrVal);

// Get CSFile object from CSVPath
destCSFile = client.getFile(dstCSVPath);
// Cast the CSFile to CSSimpleFile
CSSimpleFile destSimpleFile = (CSSimpleFile) destCSFile;
// Set the extended attributes
destSimpleFile.setExtendedAttributes(cseaCSExtAttrA);

Is it possible to share your XML file?

If memory serves correctly (haven't done much Java / CSSDK code recently) - you cannot access a member of a null pointer - which is what you appear to be doing.

You either need to allocate the storage for the array first, or you need to use some sort of method like add() or put() if such exists, or a combination of both.

Roughly (and this is completely off the top of my head and likely to be erroneous):

CSExtendedAttribute[] cseaCSExtAttrA = CSExtendedAttribute[10];

I suggest referencing basic Java manuals regarding the actual, proper syntax.

Perl does all the allocation on-the-fly so you don't have to worry about it, but Java is a stricter language and doesn't (at least for the most part) like to do memory allocation [implicitly] on-the-fly.

If you are going to use an array, you'll need to specify the number in the array for Java, like Ghoti mentioned.

If you want to use dynamic amount of data, you should use either ArrayList or Vector.

Something like:


ArrayList<CSExtendedAttribute> al=new ArrayList<CSExtendedAttribute>();
al.add(ea1);
al.add(ea2);
...

Here is my XML.
<attributes>
<attr attr="G11N/Localizable"><![CDATA[true]]></attr>
<attr attr="TeamSite/Metadata/Locale"><![CDATA[en_US]]></attr>
</attributes>

==============================

Yes, I am looking for dynamic array rather than defining the size of the array.

If I put the Ext attributes in an array list or vector, it will not allow me to set the attributes using the following command.

destCSFile = client.getFile(dstCSVPath);
CSSimpleFile destSimpleFile = (CSSimpleFile) destCSFile;
destSimpleFile.setExtendedAttributes(eaCSExtAttrA);

where eaCSExtAttrA is of type CSExtendedAttribute[] .

Create an arraylist, put in your EAs, then convert the list to an array. something like this:
[html]

List EAs = new ArrayList();
EAs .add(...);
...
destSimpleFile.setExtendedAttributes((CSExtendedAttribute[])EAs.toArray(new CSExtendedAttribute[EAs.size()]));
