I want to find where is a certain java class from from hundreds jar files. I want to use batch file to do it:
First i get a list of all jar files:
dir /s *.jar > jarfiles.txt
Then create a bacth file findclass.bat:
jar tf %1
finally i run this batch like this:
findclass < jarfiles.txt
But this does not work.
What's wrong and what should I do?
Or any other better way to locate a class than using batch?
see HELP FOR
and then try
FOR /F "delims=" %%A IN (jarfiles.txt) DO findclass %%A
or just
FOR /R %%A IN (*.jar) DO findclass %%A
I think this should work, just replace <your class name>
with your class name
@echo off
set JARTEXTFILE=jarfiles.txt
dir /S /B *.txt > %JARTEXTFILE%
for /f "tokens=1,* delims=¶" %%A in ( '"type %JARTEXTFILE%"') do (
jar tf %%A | findstr /C:"<your class name>"
)
Use my ClassFinder utility. It's simple, fast and built for the purpose!

Usage:
java -jar cf.jar SEARCH [DIRECTORY] [OPTIONS]...
Searches all JAR files in the current directory and its sub-directories for
entries matching the SEARCH argument. If DIRECTORY is provided, searching will
be done in that location instead of the current directory.
SEARCH:
A search string containing the class name (entry name). Wild card (*) is
supported. Package separator can be either of `/', `\' or `.'.
Examples:
java.lang.String
java/util/ArrayList
java/lang/Str*B*er
If non ".class" entries also need to be searched, option -a (--all-types)
should be specified. Please see the OPTIONS section for a more detailed
explanation.
DIRECTORY:
If this is not provided, current directory and all its sub-directories will
be used for performing the search. However, if this argument is provided,
the same and its sub-directories will be used as the location to fetch JAR
files from.
If a recursive scan is not needed, option -s (--shallow) can be specified.
OPTIONS:
-h --help
Shows this help
-o [path] --redirect-output
Redirect output to a file path supplied.
-x [x1,x2] --archive-extensions
Extensions in addition to the default ".jar". Comma or space
separated list accepted.
-i --insensitive-case
Case insensitive search.
-q --quiet
Silent search without the progress bar animation.
-a --all-types
Removes the filtering on ".class" types so that other types
such as ".properties", ".xml", etc can also be searched for.
-s --shallow
Performs a shallow search. Doesn't recurse.
Examples:
java -jar cf.jar org/apache/log4j/Level D:\Frameworks
java -jar cf.jar *OracleDriver C:\oracle -x jar,zip
java -jar cf.jar messages.properties D:\IBM\WebSphere -a -x jar,war,ear
java -jar cf.jar util.* D:\Java -i -q
