1. You've converted the input to upper case, but you've got references to lower-case letters in your regular expression

I am not sure I understand it correctly. Please correct me if I am wrong. My regular expression is [^a-z]*[\\s]?[^\\d\\w]?[POSITIVE\b]+[^a-z]* which has POSITIVE in caps.

2. [POSITIVE\b]+ doesn't look for the word "POSITIVE". It looks for any letters in the word "POSITIVE". I think you're confusing square and regular brackets. And with [\\s]? - why are the brackets there?

I am new to regular expression. What is regular brackets mean? is it ( ) ?

Thanks,

Hi Guys,

This is regarding composing an regular expression to satisfy the given conditions.

The conditions are:
1. I wanted to return true/false if a particular word is present in the paragraph.
2. The word can be anywhere (in the beginning, middle, or end)
3. It should return only for whole words with an exception. The word can precede (or) follow by only one special character such as ,.;()[]{} etc
4. Also it is case insensitive search.

In the below code I am searching for a word Positive. I have hardcoded the string in the regex. Ideally in this case the output should be false, but it is returning true.
So I am not sure how to do this.

String inputStr = "ssdf Positiveasd asd sdfewrewr asd"; inputStr = inputStr.toUpperCase(); String patternStr = "[^a-z]*[\\s]?[^\\d\\w]?[POSITIVE\b]+[^a-z]*"; Pattern pattern = Pattern.compile(patternStr); Matcher matcher = pattern.matcher(inputStr); boolean matchFound = matcher.matches(); System.out.println(matchFound);

Thanks in advance.

Actually there are many ways to read the contents of XML. This one is using JDom.

You can have some thing like this:

<input type="text" name="username" id="username">
<input type="password" name="password" id="password">


and then in the script function you can have

if(document.getElementById("username").value == "" || document.getElementById("password").value == ""){
alert("Username or password cannot be blank");
//elem.focus(); // set the focus to this input
return false;
}

Correction please:

if (i> 10 && i<20) { }

Thanks,

Hi Guys,

Is it possible to do the following condition in switch statement?
I know its crazy to do this using switch but my question is what level of support does switch statement provides.

if (i < 10 && i > 20) { }

Thanks,
Mahendran

William,

Thanks for your quick reply. Yes my question is "serialize objects from multiple java classes" only.

And thanks for your solution.

Hi guys,

I wants to serialize/deserialize multiple java classes into a single file. Is it possible to do that?

Thanks,

Hi Guys,

I am facing a problem with connection pooling on jboss 4.2.1GA. For every db call a new connection is created. In other words it seems to be no pooling of connections. Is there is any way to specify this in the properties. My connection properties are as follows:

<bean id="temp" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName"> <value>com.arjuna.ats.jdbc.TransactionalDriver</value> </property> <property name="url" value="jdbc:arjuna:jdbc:oracle:thin:@temp.com:1521:testdb" /> <property name="username" value="name" /> <property name="password" value="password" /> <property name="connectionProperties" value="DYNAMIC_CLASS=OracleJbossDynamicClass;" /> <property name="initialSize" value="2" /> <property name="maxActive" value="20" /> <property name="minEvictableIdleTimeMillis" value="600000"/> </bean>

Thanks,
Mahendran.

Ulf,

Currently I am handling those missing as you pointed out. But I will get more information regarding this and I will ask to make a database change if possible.

Thanks,
Mahendran.

Paul and Ulf,

Is this looks alright?

String userAgent = request.getHeader("User-Agent"); String user = userAgent.toLowerCase(); String os = ""; String browser = ""; //Test OS - if ( userAgent.toLowerCase().indexOf("windows nt 5.0") >= 0 ) { os = "Windows nt 5"; } if ( userAgent.toLowerCase().indexOf("windows nt 4.0") >= 0 ) { os = "Windows nt 4"; } if ( userAgent.toLowerCase().indexOf("windows 98") >= 0 ) { os = "Windows 98"; } if ( userAgent.toLowerCase().indexOf("windows 95") >= 0 ) { os = "Windows 95"; } if ( userAgent.toLowerCase().indexOf("windows 16") >= 0 ) { os = "Windows 3.11"; } if ( userAgent.toLowerCase().indexOf("mac") >= 0 ) { os = "Mac"; } if ( userAgent.toLowerCase().indexOf("X11") >= 0 ) { os = "Unix"; } //Browser if(user.indexOf("msie") != -1) { browser = "ie ?"; } if(user.indexOf("msie 6.0") != -1) { browser = "ie 6.0"; } if(user.indexOf("msie 5.0") != -1) { browser = "ie 5.0"; } if(user.indexOf("msie 5.5") != -1) { browser = "ie 5.5"; } if(user.indexOf("msie 5.01") != -1) { browser = "ie 5.01"; } if(user.indexOf("msie 4") != -1) { browser = "ie 4"; } if(user.indexOf("msie 3") != -1) { browser = "ie 3"; } if(user.indexOf("mozilla") == 0) { browser = "netscape ?"; } if(user.indexOf("mozilla/7.0") > -1) { browser = "netscape 7"; } if(user.indexOf("netscape6") != -1) { browser = "netscape 6"; } if(user.indexOf("mozilla/4.7") != -1) { browser = "netscape 4.7"; } if(user.indexOf("mozilla/4.78") != -1) { browser = "netscape 4.78"; } if(user.indexOf("mozilla/4.08") != -1) { browser = "netscape 4.08"; } if(user.indexOf("mozilla/3") != -1) { browser = "netscape 3"; } if(user.indexOf('opera') > -1) { browser = "opera browser"; }

Thanks,
Mahendran.

Paul,

In the database there is field to store the browser version, os version. I have requested to fill that data. That's it. No idea about why are we storing it.

Thanks,
Mahendran

Paul,

Is there any other standard API other than Servlet specification to do the parsing and return accordingly(Browser Version, Os Version etc)?

Thanks,
Mahendran.

Paul,

Through HttpServletRequest I could only get the user agent string, But I require browser version and os version which any way is part of user_agent. But my question is there any method which will return something like this

String browserVersion = object.getBrowserVersion(userAgentStr);

Thanks,
Mahendran.

Hi All,

I need to get the OS version and Browser Version from the user-agent HTTP header. Is there any standard API which should parse it and return? One more question. What is OS_TEXT, OS_CODE, BROWSER_TEXT, BROWSER_CODE in this context?

Thanks for your suggestions,

Mahendran
