linking to a web page

[Juuno]

I have an xml file which includes file name and source(which is web page link) like following:

<file>
<name>Japan</name>
<source>ttp://en.wikipedia.org/wiki/Japan</source>
</file>
<file>
<name>USA</name>
<source>ttp://en.wikipedia.org/wiki/Japan</source>
</file>

And my program accept the <name> as user input via web UI. So, when the user input 'Japan', then my program will search through the xml file and then return source, I mean the link of the web page.

But I get the text of the <source> tag as a string and when I try to return it to my JSP and run my program, there's an error when I click on the link:
ttp://localhost:8080/myfolder/%22(The request resource is not available).

I know that it's because it really doesn't exist in that folder. But what I want is to point to the actual address, like search engine.

I deleted 'h' in http bcoz my post count is less than 20. It's not program error.

How can I do this?
Thanks in advance.

You appear to be returning a " (%22) instead of the contents of <source>. Either your xml processising or your JSP is wrong.

Here is the code in my Java program:

    public Stringb showLink(String filename, String inputname){
	//filename is the name of xml file I have to search
	//inputnmae is the user input which I have to match with
	//the text of <name> tag
    	
    	String strlink="";
		String outputlink="";
    	File filetosearch = new File("C:\\matchTest\\dtafiles\\" + filename);
    	
    	{
	    	try{
    	    
	    	   	DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
	    		domFactory.setNamespaceAware(true); 
	    		DocumentBuilder builder = domFactory.newDocumentBuilder();
	    		Document doc = builder.parse(filetosearch);

	    		XPathFactory factory = XPathFactory.newInstance();
	    		XPath xpath = factory.newXPath();
	    		XPathExpression expr = xpath.compile("//body//file[name='"+inputname+"']//source//text()");
	    		    		
	    		Object result = expr.evaluate(doc, XPathConstants.NODESET);
	    		NodeList nodes = (NodeList) result;
	    				    			
	    			for (int j=0; j< nodes.getLength(); j++){
		    			strlink =  nodes.item(j).getTextContent();
	    			}	

	    	}catch(Exception e){return e.toString();}
       }
    	strlink = strlink.toString();
		outputlink =  "<a href='\"' strlink '\"'>" + strlink + "</a>";
    	return outputlink.toString();
    }

And here is the code from my JSP:

<jsp:setProperty name="obj" property="name" />     		<jsp:getProperty name="obj" property="name"/>:
<br> 

${tf:testMethod(obj, obj.name)}

And it shows the results as a valid link, for example:

Japan:
ttp://en.wikipedia.org/wiki/Japan
But the problem is when I click on that link, there's an error I described.

Do I need to download and save those web pages in my Web Server folder?
Thanks.

<a href='\"' strlink '\"'>

Exactly as I said, this gives you an href of " followed by some invalid html.

Also, why are you pointlessly calling toString() on Strings?
Are you aware that your for loop discards everything except the final iteration?

[Juuno]

invalid link??

Can you explain me more detail and how can I solve it?
Is it because of the port opened in Tomcat?

[OrangeDog]

No, it is because you don't understand either Java strings or html.

This is a link to a page about Japan

<a href="http://en.wikipedia.org/wiki/Japan">http://en.wikipedia.org/wiki/Japan</a>

This is not

<a href='"' strlink '"'>http://en.wikipedia.org/wiki/Japan</a>

[Juuno]

Then, how can I parse that string from my Java program to JSP page?

[OrangeDog]

Can you really not see why

outputlink =  "<a href='\"' strlink '\"'>" + strlink + "</a>";

gives the second example above instead of the first?
