How to read Blue Dump’s (BSOD) Minidump file

From couple of weeks in my brother’s machine he was getting Blue Dump screen with message “DRIVER_IRQL_NOT_LESS_OR_EQUAL”. Today to investigate I asked him to pass me the minidump files. Minidump are file that windows write for debugging purpose at below location:

%SystemRoot%\Minidump

in the above folder you will find files with ext .dmp
if you open this file with notepad or any other editor you will not be able to read it’s content.

XStream: Cannot parse date

I was sending date “06-14-2011” in XML request, during it’s processing i got this parse error

Cannot parse date 06-14-2011 com.thoughtworks.xstream.converters.basic.DateConverter.fromString(DateConverter.java:97)

this is because Xstream by default don’t handle MM-dd-yyyy format. So we need to add one in order to make our format working.

String[] formats ={“MM-dd-yyyy”}; XStream xstream = new XStream(); xstream.registerConverter(new DateConverter(“MM-dd-yyyy”,formats)); Object obj=xstream.fromXML(inputXML)

This will resolve the issue. =)

Mainframe CICS DB2 : java.lang.NoClassDefFoundError: com/ibm/crypto/provider/IBMJCE

I was trying to access Mainframe () DB2 using standalone application with “com.ibm.db2.jcc.DB2Driver” driver where I encountered the below error

java.lang.NoClassDefFoundError: com/ibm/crypto/provider/IBMJCE

Problem was that ibmjceprovider.jar was missing from my classpath and java.security file I added the jar file and then added below line in security file..it works.

security.provider.10=com.ibm.crypto.provider.IBMJCE

DB2 SQL error: SQLCODE: -204, SQLSTATE: 42704

SQLCODE -204 is "object does not exist".

I was getting this error while executing a query, this was happening because I was using the SCHEMA name of Q7 database and executing the query inside Q0 db.

means not able to find table with given user id.

When I corrected the db name it works fine.

This error also appear when you are not using schema name in query.

Today I was  trying to cleanup a project, I got error.

I tried deleting the log file in the .svn directory and I also deleted the offending file in .svn/props-base

then did the cleanup. It works and I resumed my updates.

In some cases you need to apply the same in parent folder as well.

HowTo Get RID of Just-In-Time debugger

I installed Visual Studio, and with this it installed a Just-In-time script debugger .This Just-In-Time seems to come up all the time when I run Internet Explore and on each page of IE.

 Solution

Open Start>Control Panels>Internet Options: Advanced and activate (check box)

* Disable Script Debugging (Internet Explorer)
* Disable Script Debuggung (Other)

Open the registry (use regedit, Click Start, Run, Regedit).

Go to this key:

HKEY_CURRENT_USER\Software\Microsoft\Windows Script\Settings\JITDebug

And set it to 0.

I checked the java.security and found that all the providers are registered correctly:
security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.net.ssl.internal.ssl.Provider
security.provider.3=com.sun.rsajca.Provider
security.provider.4=com.sun.crypto.provider.SunJCE
security.provider.5=sun.security.jgss.SunProvider

I did some analysis, when i run the code from a windows batch file, it works but if i run it within Eclipse, it throws this Algorithm not found exception. i checked the JVM version and classpath and it looks okay.

I make a little program to find out whether all the providers are available during runtime or not
 Provider[] provs = Security.getProviders();

In result I get only one privider and all other were missing. The jar was not getting loaded in eclipse tomcat during runtime.

For solution, I added following three jar files in tomcat boot classpath and it worked form me and my team members Smile

-rt.jar
-jsse.jar
-jce.jar
