Hi,

When I set back the datetime on my machine and start up JBoss , the log in freezes. If I open multiple browser wndows and attempt logins from each , they go thru fine. It almost seems as if the first thread waits for other requests to somehow push it through.

Does the war / JBoss contexts have any impact when we set back the date time on the server?

Thanks

Thanks Greg & Preity.
Greg , you are right , what am comparing is the UI entity versus its old copy that was stored in the DB. They are different class types for sure , but have the same set of properties.
By 24 out of 30 I meant the dirty flag had to be set only when certain properties are updated and not all.

Preity , thanks for the input. I was trying to get to a generic way of coding this versus writing it all out in a block of If statement with multiple OR conditions.

Looks like the only way out.

Thanks again

What would be a smart of checking if an object is dirty especially if am looking at only a subset of its properties for a change

Eg. class Person should be have a field updated if and only if 24 specific properties out of its 30 properties are modified

instead of defining a method like

private boolean hasChanged(Person p1 , Person p2){
if(!p1.getAttr1().equals(p2.getAttr1()) ||
!p1.getAttr2().equals(p2.getAttr2()) ||
!p1.getAttr3().equals(p2.getAttr3()) ...
......................................
return true;
}
return false;
}

I dont want to use reflection just to accomplish this. Is there a better design for checks like these?

Thanks
Menon

Has anybody got a solution to this? I have the same problem

Hibernate seems to append a ',' after the table name in the update HQL

Thanks

Hi,

My webservice call returns an XMLStreamReader. I would like to know how to extract just the string representation of the whole xml so that I can dump it in the DB for future processing.

I short , converting the XMLStreamReader's content into an outputstream is what I need.

Can someone help?

Thanks in advance

Hi,

I am invoking a web service call from my client application and it seems to work from certain machines alone.

The error that is thrown is as follows:

Caused by: org.apache.axis2.AxisFault: Address information does not exist in the Endpoint Reference (EPR).The system cannot infer the transport mechanism. at org.apache.axis2.description.ClientUtils.inferOutTransport(ClientUtils.java:65) at org.apache.axis2.client.OperationClient.prepareMessageContext(OperationClient.java:302) at org.apache.axis2.description.OutInAxisOperationClient.executeImpl(OutInAxisOperation.java:174) at org.apache.axis2.client.OperationClient.execute(OperationClient.java:163)

Please help!

Rectified the problem.

You can set the time out on the client side in the following manner:

stub._getServiceClient().getOptions().setTimeOutInMilliSeconds(7 * 60000); //increase timeout to 7 minutes

Hi,

I am invoking a webservice in a for loop. The service is synchronous and I have tried applying a thread sleep so as to wait before I make the next call in the loop :

[code]
for(...)
{
WS client call

Thread sleep
}

I still get a read time out , the first couple of iterations go thru fine though.

Please let me know what can be done.

Thank you.

Thanks Travis.

I am using Rampart on the client side.

My Web App is a consumer of a Web Service which requires Rampart for client authentication. Hence inorder to fire those web service calls , I need to package Rampart.mar in my WAR file.

I though all files under WEB-INF/lib would be loaded by the classloader and hence be on the classpath.

Seem to be runnning into issues configuring this

Thanks Ulf , for pointing that out.

Is packaging the rampart.mar file directly under src folder considered a good practise?

Am keen on bundling it all up in the app and am trying to figure out the best way to do it.

Or better still , do you think the class path attribute when I build the WAR file can be tweaked to accomodate these files n the classpath?

Hi Ulf,

Thank you for you quick response.

Will I have to pass this path as well? I am using the following method

createConfigurationContextFromFileSystem(String path, String axis2xml)

where path is null and the axis2xml file is specified.

Since path is null , it looks for it in the classpath. So if I am to place the *.mar file in the WEB-INF/module directory , will it automatically look it up? I mean , is it like a default path?

Hi,

I am using rampart for WS security in my app.

I have placed the rampart.mar including the rampart jars in my WEB-INF/lib folder. For some reason , it doesnt seem to be able to read the file from the classpath. Please let me knwo what needs to be rectified. I do not want to point to a folder outside my app and want to pack in rampart along into my WAR file.

Caused by: org.apache.axis2.deployment.DeploymentException: The system is attempting to engage a module that is not available: rampart at org.apache.axis2.deployment.DeploymentEngine.loadFromClassPath(DeploymentEngine.java:160) at org.apache.axis2.deployment.FileSystemConfigurator.getAxisConfiguration(FileSystemConfigurator.java:134) at org.apache.axis2.context.ConfigurationContextFactory.createConfigurationContext(ConfigurationContextFactory.java:64) at org.apache.axis2.context.ConfigurationContextFactory.createConfigurationContextFromFileSystem(ConfigurationContextFactory.java:180)

Thank you.

Hi Preethi,

You can try appending the request parameters directtly to the servlet URL -

url ? param1 = value && param2 = value.

In your servlet code , you can retrieve it using request.getParameter("param1").

Hi,

I need to locate the path of the file - rampart.mar which I have placed in the folder <proj>/lib

To locate the path at runtime, I tried executing the command :

String repositoryLocation = this.getClass().getClassLoader().getResource("rampart.mar").getPath();

It fails!

I realised that since my output folder in eclipse is set to build/classes , all the resource files that are placed under the src folder can be read in the above manner ,since post compilation they will be present in the folder build/classes.

How can I read the 'rampart.mar' file which is more of a runtime dependency jar?

Hope to hear from someone on this

Thank you!!
