I am new to the topic : Web Services

can anybody please help in by telling me how to proceed.I have downloaded a tutorial from the sun website, I have the java SDK and the tomcat server loaded in my computer.

I am getting hundreds of results for web services when I browse but I am not sure how to proceed.

Thanks
Chinni

Hai Anjali,

firstly Congratulations

I had passed the exam just on last sunday and got my logo on wednesday , I have used it in my resume.

Bye

I got my certification logo yesterday and I wanted to post about that because we can use the logo in our resume to let snyone know that we are SUN Certified officially


Bye

Chinni

Happy to tell that I have finished the SJPC exam within 2 weeks, I did not get a very good score.I got only 70%

I studied the Kathy Sierra and Bert Bates book and it was very helpfull. I did not refer any other book.
I tried to do some mock exams but was not able to do because I took the exam in a short period.

This website is very helpfull in knowing many things about JAVA.

I thank Kathy Sierra and Bert Bates for their explanation , examples and the two minute drill's.

Thanks once again

Chinni

Hi Kiran,

The K&B is the best material you can get for preparing SPJC.It is having nice information about the key points we need to keep in mind for the exam.

All the BEST

sorry I pasted different code,
this is the correct one

String s0 = new String("Java");
System.out.println(
" The String is a new string and it has the reference to the string s0 ="
+ s0);
String s1 = s0.trim();
System.out.println(" The string s1 = s0.trim() = " + s0);
String s2 = s0.substring(0, 4);
System.out.println(" The string s2 = s0.substring(0, 4) = " + s2);
String s3 = s0.replace('K', 'a');
System.out.println(" The string s3 = s0.replace('K', 'a') = " + s3);

System.out.println(" The String s0 =" + s0);
System.out.println(" The String s1 =" + s1);
System.out.println(" The String s2 =" + s2);
System.out.println(" The String s3 =" + s3);
System.out.print("s0 == s1 = ");
System.out.println(s0 == s1);
System.out.print("s0 == s2 = ");
System.out.println(s0 == s2);
System.out.print("s0 == s3 = ");
System.out.println(s0 == s3);



The String is a new string and it has the reference to the string s0 =Java
The string s1 = s0.trim() = Java
The string s2 = s0.substring(0, 4) = Java
The string s3 = s0.replace('K', 'a') = Java
The String s0 =Java
The String s1 =Java
The String s2 =Java
The String s3 =Java
s0 == s1 = true
s0 == s2 = true
s0 == s3 = true

you are correct I just wanted to show that u are correct

Naresh,

I just added few print out statements to show how the strings work. s0 is a new string having reference to the string "java", s1, s2, s3 are the strings which are used to work on the string "java" but they are loast as soon as they are done and you can see that in the below listed code. Strings are immutable.

*----------------------------code----------------------------------------*

String s0 = new String("Java");
System.out.println(
" The String is a new string and it has the reference to the string s0 ="
+ s0);
String s1 = s0.trim();
System.out.println(" The string s1 = s0.trim() = " + s0);
String s2 = s0.substring(0, 4);
System.out.println(" The string s2 = s0.substring(0, 4) = " + s2);
String s3 = s0.replace('K', 'a');
System.out.println(" The string s3 = s0.replace('K', 'a') = " + s3);

System.out.println(" The String s0 =" + s0);
System.out.println(" The String s0 =" + s1);
System.out.println(" The String s0 =" + s2);
System.out.println(" The String s0 =" + s3);
System.out.print("s0 == s1 = ");
System.out.println(s0 == s1);
System.out.print("s0 == s2 = ");
System.out.println(s0 == s2);
System.out.print("s0 == s3 = ");
System.out.println(s0 == s3);
*---------------------------------------------------------------------*

The String is a new string and it has the reference to the string s0 =Java
The string s1 = s0.trim() = Java
The string s2 = s0.substring(0, 4) = Java
The string s3 = s0.replace('K', 'a') = Java

The String s0 =Java

s0 == s1 = true
s0 == s2 = true
s0 == s3 = true

Hi,

I am planning to take the exam on the 10th of this month , I have already scheduled the time with the prometric center.I am preparing hard for the exam.


I am preparing from the Kathy sierra book and it is very nice , it has the quizes along with the answers and explanation.

"Just be confident and work hard" these are the words I hear from the people who took the exam recently.

I get the below listed error when I try to run my project in NetBeans, I had run this application few days back (like 3 months )and I have not changed any code. Now if I try to run I get the error. It is project I did using JSP's , java script , Servelets . can anybody give me some ideas


"Deployment error: TomcatManager.undeploy invalid TargetModuleID passed. See the messages.log file for details."
