Hello,

I am retriving some data based on URL. This URL internally acts as webservice client to fetch data from other location and returns back the data.
There are chances that the webservice will be down which will directly impact in fetching the data.
What percaution should be taken to avoid such scenario? Is there any way we can add some time constraint or make the call asynchronous?

URL url = new URL("https://www.mydomain.com/services?id=" + 10); URLConnection connection = url.openConnection(); connection.setDoOutput(true); connection.setRequestProperty("METHOD", "GET"); connection.setRequestProperty("User-Agent","DesignOnDemand / " + System.getProperty("os.name") +" (" + System.getProperty("os.version") + ")"); connection.setRequestProperty("Content-Type", "text/html"); inBufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream())); String line = (String)inBufferedReader.readLine();

Your help is highly appreciated.
Thanks in advance.

Hello,

We are facing problem when we have '&' in our query string. For example http://somehost/somepage.jsp?key1=value1&key2=A&B.

Here key2 value is A&B but because & is a separator for query string, we only get A as value.

We cannot really use POST here because this is a hyperlink and not a form submit.

How can I fix this so that I can correctly get values in the target page of hyperlink on server side (somepage.jsp).

Hello,

I want to show the checkbox list (say 30 languages) in 10 rows X 3 columns format.

Currently i am using h:selectManyCheckbox. One of the attribute for this tag "layout" has only two options pageDirection / lineDirection.
With those options the checkboxes can be arranged in 'n' rows X '1' column or '1' row X 'n' column format.

Is there any other way to satisfy this requirement? Your help is much appreciated.

One more thing, EL is frequently visible on the exam codes. So be prepared for that one too.

you can use the '/' notation in servletrequest

this is exactly opposite. When you get the RD object from context then you have to use the context path. (which starts with '/')

how ever when you get the RD object from the request, then you can use the relative path. Here it is container's responsibility to convert this relative path to real path.

1. Filters follow stack processing.
2. The control always comes back to the filter thru which it has passes in the reverse sequence.
3. And being you have wrapped the container's response object, you are not writing directly to the response object but your own custom made response object.
4. So once you come back from the servlet in the filter, then you can take action on what needs to go to response.

So the notification from the servlet to filter always happens whether it is wrapped response or not. It is just a matter that you have wrapped the response hence container didn�t have any chance to write to the actual response object.

I hope, this clarifies your doubt.

Hi Brijesh,

The correct answer is 4.

This question is more on the JSP comments vs HTML comments.

As you said, the output is blank. However, if you see the source code of the page, then you will realize that its not blank. The expression is executed and date is displayed. Because of the HTML comments it is not visible in the browser. So user can see the comment (via source code ) hence answer 4 is correct.


If the code would have been in JSP comments then answer 2 would have been correct. <%-- JSP comment text --%>

<ul> <h:dataTable id="outerpm" value="#{beanRef.verArrayList}" var="kmorder" border="0"> <h:column><f:verbatim><li></f:verbatim> <h:outputText escape="false" value="#{kmorder} "/> <f:verbatim></li></f:verbatim> </h:column> </h:dataTable> </ul>
