How to Find a JAR File Which Contains a Particular JAVA CLASS Object?

How to find a jar file which contains a particular JAVA CLASS object
--------------------------------------------------------------------

1) Find invalid java classes:
   --------------------------
Lets assume that we have two JAVA CLASS invalids as returned by the
following query:

SQL>SELECT object_name,object_type,owner,status FROM dba_objects
WHERE object_type='JAVA CLASS' AND status='INVALID';
OBJECT_NAME                    OBJECT_TYPE OWNER   STATUS
------------------------------ ----------- ------- -------
/b0993e19_MyAppsContext        JAVA CLASS  APPS    INVALID
oracle/apps/fnd/common/FileLog JAVA CLASS  APPS    INVALID

2) Try to resolve invalids:
   ------------------------
First of all try to resolve these invalids using following statements.

SQL>ALTER JAVA CLASS "/b0993e19_MyAppsContext" RESOLVE;
SQL> ALTER JAVA CLASS "oracle/apps/fnd/common/FileLog" RESOLVE;
Note: If you don't include java class name in double quotes the statements will fail.

If these objects are still invalid proceed to next step

3) Find respective modules of java classes:
   ----------------------------------------
We need to check as to which module the JAVA CLASS belongs.

To check the module of first invalid run the following statement:
SQL>SELECT dbms_java.longname('/b0993e19_MyAppsContext') FROM dual;
DBMS_JAVA.LONGNAME('/B0993E19_MYAPPSCONTEXT')
---------------------------------------------------
oracle/apps/wms/cartonization/server/MyAppsContext

The result of this query shows that this java class is associated 
with WMS module as it is included in oracle/apps/wms package

From the name of second invalid above, FileLog, it is clear that it is
associated with FND module as it is included in oracle/apps/fnd package.

4) Find jar file which includes the java class:
   --------------------------------------------
Create a shell script, say, whichjar.sh with the following logic:

#!/usr/bin/ksh
for f in `ls $1/java/jar/*.jar`
do
        t=`strings $f | grep $2`
        if test ! -z "$t"
        then
                echo "$2 is found in $f"
        fi
done 

Now run the script with the following command:

$./whichjar.sh <$PRODUCT_TOP> <CLASSNAME>

$./whichjar.sh $WMS_TOP MyAppsContext
MyAppsContext is found in /u01/visappl/wms/11.5.0/java/jar/wmscrtzn.jar

$./whichjar.sh $FND_TOP FileLog
FileLog is found in /u01/visappl/fnd/11.5.0/java/jar/fndaolj.jar
