Dear All,
I am facing a problem in bindandvalidate in spring webflow.I enetred some values in jsp then enters into binder and it does the binding properly. even I am able to see the binded values in the validator. But after validations, if it has any error then it will forward to the same jsp, here in the jsp I am not getting the entered values.
Somehow the value is getting missed but in my validator i used a print statement at the last here its displaying the value but its getting missed in the jsp. Can you please help me in this?

Thanks in advance,
Prabu

Hi All,
I need a help from you all. I need to upload a file from client machine to server. I did it using MultipartHttpServletRequest API. Now i want to get the last modified date of a file.I used file.lastModified method to get the date but it returns the date when we upload the file to server, it not returns the original last modified date. Let me know is it possible to get teh file last modified date from the client side itself using javascript?


Thanks in advance.

I don't think the problem is because of WebSphere.I hope its because of soem version problem between the jars. I tried to find it but i was not able to check it. Ok i will check it with WebSphere admin also meanwhile if anyone of you come to know the reason please reply for this.

Thanks,

Hi McKenzie,

Thank you very much for your reply. I'm using WebSphere 6.1 in Linux environment. Ya i tried with class loader option PARENT_FIRST but still am facing the same problem. I'm using Java 1.5 and j2ee 1.4 version.

Hi All,
I have created a hiberante application. while starting the server itself i try to read the hibernate config file and create the session factory.But when i start the server i'm getting java.lang.IncompatibleClassChangeError exception.In my project am using the following jars.

antlr-2.7.6.jar
antlr-2.7.6RC1.jar
asm.jar
asm-attrs-1.5.3.jar
backport-util-concurrent-3.0.jar
cglib-2.1.3.jar
cglib-nodep-2.1_3.jar
commons-collections-3.1.jar
commons-lang-2.3.jar
commons-logging-1.1.jar
dom4j-1.6.1.jar
ehcache-1.3.0.jar
hibernate-3.2.5.ga.jar
jsr107cache-1.0.jar
jta-1.0.1B.jar
log4j-1.2.14.jar
spring-2.0.8.jar
spring-hibernate3.jar
xalan.jar
xercesImpl-2.8.0.jar
xml-apis.jar

Here i have attached the logs also please find it, because of the IncompatibleClassChangeError i'm not able to create the sessionfactory.It was working fine at WAS6 in AIX but now its not working in WAS6 in Linux. Please let me know what could be the reason for the exception.Think the problem is with jars but am not able to find it.
