(Java) Using DebugLogFilePath to Debug a CrashIf a crash is suspected to occur within a Chilkat method call, it can be debugged using the VerboseLogging and DebugLogFilePath as shown here.
import com.chilkatsoft.*; public class ChilkatExample { static { try { System.loadLibrary("chilkat"); } catch (UnsatisfiedLinkError e) { System.err.println("Native code library failed to load.\n" + e); System.exit(1); } } public static void main(String argv[]) { // If a crash is suspected to occur within a Chilkat method call, it can be debugged using the VerboseLogging and DebugLogFilePath as shown here. // // NOTE: The same technique applies for any Chilkat class that has the DebugLogFilePath property. // Most Chilkat classes have DebugLogFilePath. CkCrypt2 crypt = new CkCrypt2(); // First make sure VerboseLogging is turned on. crypt.put_VerboseLogging(true); // Set the DebugLogFilePath to the path of a log file that will be created automatically. // If the file already exists, Chilkat will append to it. crypt.put_DebugLogFilePath("c:/someDir/debugLog.txt"); // Reproduce the problem. // ... boolean success = crypt.VerifyP7M("c:/someDir/someFile.p7m"); // ... // If a crash occurred within Chilkat, then the debugLog.txt will contain information that // can be sent to support@chilkatsoft.com // ------------------------------------------------------------------------------------------------ // Note: Given that the debug log file is always appended, the log file might grow // to a very large size. You can prevent the continual growth of the log file by // deleting the log file at certain points, such as after a Chilkat method returns. // // Given that we're only interested in the log file for Chilkat calls that crash or hang, // it's OK to delete the log file after a Chilkat method that returns. // // The next call to a Chilkat method will re-create the log file. If the Chilkat call crashes // or hangs, then you'll be left with just the log of the crash or hang. // ------------------------------------------------------------------------------------------------ } } |
