I often see catch clauses for Throwable in Blackberry documentation, such as the Network API docs . My sense is that this is not generally a good practice in Java. Is there a reason for this in Blackberry programming? Does it have to do with stack trace generation for Throwables? Michael Donohue When you catch Throwable in a BlackBerry app, not only does it preserve the stack trace, it saves that stack trace in the device event log. There is no way for an app to get a stack trace itself , so unfortunately you can't automatically collect stack traces. To view the stack trace, you pull up the

My apps has AutoCompleteField that hold long text more than 100 Characters, if I use regular AutoCompleteField I cant read the rest of data. How can I make the text wrap into 2 or more lines in the autocompletefield options ? I try using '\r'+'\n' and '\n', its not giving new line. setting it size and also set row height doesnt give me the result I wanted AutoCompleteField autoCustomer = new AutoCompleteField(custList, style); autoCustomer.getListField().setSize(20); autoCustomer.getListField().setRowHeight(100); If I was you I would override drawListRow and draw the text using drawText which

I created a BlackBerry application using java-me and the BlackBerry specific API. It works fine on the BlackBerry simulator. I want to know how I can deploy this application to a BlackBerry device. From the documentation I found that some code signing is required to run a BlackBerry application on a device. What is this meant for? Do all applications required this code signing? and what are the steps to build my application to run on a BlackBerry device? Dinesh Sharma There are basically two ways to install a Blackberry app on a device: Over The Air (OTA) using Desktop Manager There are

Hashtable iHashtable=new Hashtable(); iHashtable.put("Name", "Jhon"); iHashtable.put("Address","India"); Enumeration iEnumeration=iHashtable.keys(); while(iEnumeration.hasMoreElements()) { Object iresult1=iEnumeration.nextElement(); String iresult2=(String) iHashtable.get(iresult1); System.out.println(iresult1); System.out.println(iresult2); My problem is I want to put the value at LWUIT table dynamically using the HashTable key and value,here is iresult1 and iresult2,using the key and value I want to create the LWUIT table where the value will be shown in the following form.

I want to create recursive directories ( for example : Connector.open("file:///Phone:/folder_1/folder_2/", Connector.READ_WRITE); ). The problem is that the two folders , here folder_1 and folder_2, are not mentioned explicitly but instead there is only one String parameter provided from a method. For example : private void myMethod(String path) { fcDir = (FileConnection) Connector.open("file:///Phone:/"+path+"/", Connector.READ_WRITE); ... } And in runtime the two folders are not created ! So I must create separately two FileConnection in order to create the two folders ! So why J2ME is not
