1. Re: Can we able to store a xml file as a value in Infinispan cache.
manik Jul 20, 2010 7:59 AM (in response to savin7)Of course you can. Details would depend on how you want to store it though - as raw bytes or as a parsed XML DOM tree, or some other representation.

savin7 Jul 25, 2010 2:27 AM (in response to manik)I want to store it as raw bytes and as well as a parsed XML. Kindly provide me the details, how to store these representations.

manik Jul 26, 2010 6:31 AM (in response to savin7)You'll want to look at the documentation on your XML parser then.

4. Re: Can we able to store a xml file as a value in Infinispan cache.
savin7 Jul 27, 2010 7:48 AM (in response to manik)Dear Manik,
I have a set of questions to you.
QUESTION 1:
I am having a plain Xml file. As per my understanding, If I have to store this file in Cache then I have to convert this file to String and then put it in cache as below code.
public class OurXmlTest {
/**
* @param args
*/
public static void main(String[] args) {
String filepath = "D:\\Response.xml";
Configuration c = new Configuration();
c.setExpirationLifespan(60000);
EmbeddedCacheManager manager = new DefaultCacheManager();
manager.defineConfiguration("demoConfig", c);
Cache<String, String> cache = manager.getCache("demoConfig");
cache.put("test", convertXmlToString(filepath));
String test = (String) cache.get("test");
System.out.println("XML String is : "+test);
}
public static String convertXmlToString(String filepath) {
StringBuffer output = new StringBuffer();
try {
BufferedReader in = new BufferedReader(new FileReader(filepath));
String st;
while ((st=in.readLine()) != null) {
output.append(st);
}
System.out.println(output.toString());
in.close();
}
catch (Exception fx) {
System.out.println("Exception " + fx.toString());
}
return output.toString();
}}
What I wanted to know is ? Is there any other better approach is there to store a xml file in cache rather than the above code. If so kindly let me know.QUESTION 2:
If I store the XML in Cache. Will I able to query the XML using Hibernate Search or Lucence? or I can only able to query Java objects using Hibernate Search and Lucene. Please clarify.
QUESTION 3:
If I want to store it as a parsed XML DOM tree. How I can do that. Please provide me the sample code snippet for the same.
Hope I am loading you with questions Kindly help me out in this.

If you store the XML as a String, then yes, you will be able to run a full-text search on the contents of the String. If it is some other object type, as long as the attributes are properly annotated, you will be able to index and search for them. See Querying Infinispan

Yes, you are loading me with questions. Dude you're asking me about how best to parse XML. There are loads of techniques out there, well outside of the scope of Infinispan. I recommend reading up on things like SAX parsers, DOM trees, maybe JAXB and perhaps pick up a good book or two on Java and XML.
