Thanks Evan,

I have run the ladder up to university master degree long ago and have several years of working experience as technical manager and midrange architect.
OOP, UML and software patterns already are in my toolset.

I'm just curious about what software architect certifications or courses are highly regarded by the ranch users.

Best reggards,

I agree that UML as software patterns are part of the required skills/tools for a software architect but I expect recommendations of courses or certificates.

Hi,

You could use a Spring 3 Validator that cheks user, first and last name against the password using the java "java.util.regex" api.

Best regards,

Thanks Ritchie for share your point of view.

Well then keep tracking back :-)

The problem could be the select
SELECT * FROM bkpl where bkpl.Af_Scheme_Number=? <sql:param value="${param.Af_Scheme_Number}"/>
try to remove the question mark
SELECT * FROM bkpl where bkpl.Af_Scheme_Number=<sql:param value="${param.Af_Scheme_Number}"/>

Cheers,

Sorry Supun,

Maybe I'm wrong but seems to me a client trace not a server trace of the error.
"com.sun.xml.ws.transport.http.client.HttpTransportPipe"

Where this trace comes from <your_bea_instance>.log, <your_bea_domain>.log, weblogic error, weblogic out ?


Best regards,

Hi Priya,

What do you get when iterating the query result?
<sql:query var="bkplQuery" dataSource="jdbc/erpl"> SELECT * FROM bkpl where bkpl.Af_Scheme_Number=? <sql:param value="${param.Af_Scheme_Number}"/> </sql:query> <c:set var="bkplDetails" value="${bkplQuery.rows[0]}"/> <c:forEach var="row" items="${bkplQuery.rows}"> <c:out value="${row.<att1>}"/> <c:out value="${row.<att2>}"/> <c:out value="${row.<att3>}"/> <c:out value="${row.<att4>}"/> </c:forEach>

Cheers,

Hi Dinesh,

Your reference documentation already have an ant target to generate the client code "<target name="webservice.client">" in a client jar.
If you run this target something goes wrong?

Best regards,

Hi Priya,

Try to replace in your servlet code
Af_Scheme_Number = request.getParameter("afno");
for Af_Scheme_Number = request.getAttribute("afno");
since you placed the "afno" value in the jsp request as an attribute
<% request.setAttribute("afno","${bkplDetails.Af_Scheme_Details}");%>

Best regards,

Hi all,

This thread lead me to a performance question.

Before I could invoke the intern method on a String object, I have to instantiate it, therefore I have spend resources in this step
(I understand that instantiation is a really expensive step) then the String reference from the heap (could be garbage collected) is replaced by a reference from the pool.

From a performance perspective couldn't be more optimal to have an additional static method 'String.intern("Legend")' that makes unnecessary to create the String in the pool.
What do you think?


Best regards,

Hi Mike,

Your new String goes to the heap, say with reference "H23", and when you force it to be placed on the pool gets a diferent reference, say "P44".
If you create a new string s3 "Legend" and force it to the pool then gonna have the same reference "P44".
String s1 = new String("Legend"); String s2 = s1.intern(); System.out.println(s1==s2); //>> It is printing as false String s3 = new String("Legend"); System.out.println(s2==s3); //false s3 = s3.intern(); System.out.println(s2==s3); //true


Best regards,

Hi,

Since is a server issue perhaps the server trace (weblogic) could give us some more insight.
Could you attach a excerpt from the server log?

Best regards,

Hi,

The literates say that synchronize(this) inside a method is exactly the same that synchronize the method
class KitchenSync { private int[] intArray = new int[10]; void synchronized reverseOrder() { int halfWay = intArray.length / 2;
because the synchronization in the 2 cases is over the object instance.

I would check now this with a class bytecode dump (just for fun),

Best regards,

Hi,

Try to change the dependency for javax.annotation in the pom.xml to

<dependency> <groupId>javax.annotation</groupId> <artifactId>javax.annotation-api</artifactId> <version>1.2-b04</version> </dependency>

You can check the maven central repository web site for current avalaible artifacts, for example javax.annotation
maven central

Best regards,

Hi,

This works for me.
1) Add the below profile to your pom.xml
2) Execute this maven command mvn validate -P libs

<profiles> <profile> <id>libs</id> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>copy-libs</id> <phase>validate</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <outputDirectory>${basedir}/libs</outputDirectory> <stripVersion>false</stripVersion> </configuration> </execution> </executions> </plugin> </plugins> </build> </profile> </profiles>
