I noticed following error in my project in eclipse. Cannot nest 'projectname/src/main/java' inside 'projectname/src'. To enable the nesting exclude 'main/' from 'projectname/src' due to this error also my test of junit was not working. and problem was due to reason that i changed eclipse java project into maven project and in the pom file eclipse added  <sourceDirectory>

In Eclipse I noticed sometimes for maven projects  (mostly i assume if eclipse project converted in maven project nature)  if you notice compilation error "package org.junit does not exist" that means he is unable to find annotation class while doing compilation. following could be the probable errors. 1. in your pom file you did not add the dependency of junit  add it as

I faced problem while compiling xsd to java using apache xmlbeans maven plugin that generated code was not matched same as in xsd, given xsd file has special German character in element as <xs:enumeration value="in Ablöse"/> and when it gets converted to java expected as static final Enum IN_ABLÖSE = Enum.forString("inAblöse"); my maven plugin was failed to write proper

Recently while working on web services I faced following problem where I was bound to use jdk1.6 to create web service because current version of weblogic11g and 12c works on jdk1.6.

To test web service I am using JMeter 2.10  with OSB (Oracle Service Bus), testing worked fine, but when we tried to send some special characters like 'ÖÜÄ' etc in XML data of  SOAP request I found that OSB was not able to parse it.  after several checks I also checked that when sending soap request XML has  UTF-8 encoding xml request look like &lts:envelope xmlns:s="

I hope you already have a basics of the JMS concpet, a bit more about it in different way. 1. when to use JMS or when a test case or secanrio to eligible for use JMS?     1.

Recently I come across above error on weblogic 12c migration project, since  for my test I used fexisting old ear that was built for weblogic 10.0.2 version. Later I found that this error has caused a problem because application is using pre-compiled jsps inside, I also noticed that weblogic 10.3.0  this jsp compilation has been depricated. so the solution was to remove the

one of our project team using webservices using Axis2 in their project discovered that, Axis is creating lot of temp files in temp folder and that was casuing to too many file handles open and out of disc space problems. This has caused because of Axis2 was creating modules jars files on every request initiated by the client code. this is an unavoidable situation because Axis2 classloader

jasperreports gives us numerous properties settings that we can customize at design or compile time and modify/control the execution of reports. Jasperreports has his own default settings and it reads it from its jar file jasperreports-x.x.x.jar with the file name default.jasperreports.properties, unless you specify differently. Property file gives us flexibility of changing its execution

In my previous article I have very briefly explained how  PLSQL has been supported in jasperreports. But it is not that easy when it comes to different databases. Here I will present how we can call stored procedure from jasperreports. For this sample I have used iReport  4.1.2 designer and Oracle database, it is supported in previous versions as well, may be with minor changes.

if you create a modal dialog window and try to access any function from parent window, well its not possible, any browser will not allow you to access parent window functions unless it is a normal window. so the alternate possible solution is as below modal window can return a value to parent window's calling function, so based on its value you can either change parent window variables or call

I am not very sure from which version Jasper started supporting this feature, but recently when I was evaluating 3.7.5 version I suddenly explored this... and it is so easy...! Well here it is how...  when you write a query in the querystring tag, Jasper has added a property called "language" and here it supports for different languages querystring. so for calling a procedure from jasper

creating a crosstab report with jasper is became very easy task now... as I explore it I found it very easy and simple to do... the most tedious task was earlier to manage with the query to get the data in cross format. since there was no alternate or easy feature available from database either. but for now with japserreport it become so easy that you don't have to modify your query at all just
