tomcat7部署war,jar写权限无法获得# Java - 爪哇娇娃

1 楼

接手了一个别人的项目，目前功能部分已经调通了，现在前端部署遇到了一些问题。前
端才用zk，zk里面嵌入一些java code。
整个page，data打包成DCL.war，我把它拷贝到/var/lib/tomcat7/webapps/下面,chmod
to 755, chown to tomcat7:tomcat7.运行localhost:8080/DCL/解压，页面正常显示~
但是运行提交页面的时候出现java.io.FileNotFoundException: cache.csv (Permissi
on denied)
这个cache.csv.是从我的某个jar写出来的，我改了相应目录的权限好像还是不行，我在
‘/etc/tomcat7/policy.d/03catalina.policy’加入了写权限：
grant codeBase "file:${catalina.base}/webapps/DCL.war" {
permission java.security.AllPermission;
permission java.io.FilePermission "file:${catalina.base}/webapps/DCL/-", "
read, write";
}
grant {
permission java.io.FilePermission "file:${catalina.base}/webapps/DCL/WEB-I
NF/lib/-", "read, write";
}
好像还是，不知道问题出在哪里。
大家帮忙看看哈~~
谢谢！

Usually this is about the user that starts the tomcat. That user needs
to have write priviledge to that directory.

tomcat7 is started when first boot up. Is it root or my account or tomcat7
user. My account has admin priviledge that allows writes. I change owner of
the DCL.war to tomcat7. Is this right?
Many thanks.

Tomcat should use “jsvc” to start itself as a service. "jsvc" has a
command line parameter "--user". Most probably that user is set to tomcat.
Check the init file, in /etc/init.d if you use RHEL.

I changed everything tomcat7 possibly can touch to 777. Looks like it's not

I checked /etc/init.d/tomcat7. --user was followed by TOMCAT7_USER, TOMCAT7_
USER=tomcat7. What else I need to check? I can provide more information if
needed.

That means user "tomcat7" is running tomcat. After it's running, you can run
this command to confirm:
ps -ef|grep tomcat
As goodbug said, just give tomcat7 the right permission to the file/dir.

You should show the full exception stack, maybe there's something
else. You should give the user the priviledge to the folder you want
to write, the war file doesn't count.
Sometimes you get permission denied in writing because the
folder doesn't exist.

I change the permission/owner of the folder and file, I can provide further
info if needed.
I don't know where did the code write to 'cache.csv'. Do you think a redo of
war file will help? BTW, how do I generate war file correctly(with
configuration, every setting right)?
Many thanks!

maybe the project was developed on windows platform and save the file to an
external location. check the above source and see if you can find the proble

cache.csv was created in class DataCache.
public class DataCache {
private static final String FILENAME = "cache.csv";
private static final double TOLERANCE = 0.1;
private static List memCacheCoord = new ArrayList<
Coordinate>()
;
private static List memCacheConte = new ArrayList();
.....
public static void addValue(double lat, double lng, Object data) {
try {
DecimalFormat format = new DecimalFormat("####.##");
String line = format.format(lat)+";"+format.format(
lng)+";"+toString(data
)+"\n";
// Store in file
FileWriter writer = new FileWriter(new File(FILENAME
), true);
writer.write(line);
writer.flush();
writer.close();
// Store in memory
memCacheCoord.add(new Coordinate(lat, lng));
memCacheConte.add(line);
} catch (IOException e1) {
e1.printStackTrace();
}
}
.....
};
I am not sure where exactly cache.csv was written to.

You need to find out where this path is. Use
File.getAbsolutePath() to determine that. My guess is this
pointing to a shared tomcat directory that's not writtable, not
the app home directory.
Or you may append a temp directory before the hardcoded filename.
System.getProperty("java.io.tmpdir"));

);

check if you can create a file "cache.csv" at where the application is deplo
yed. chmod it to 777, and then try running your program again.

Looks like there is still problems when packing the war files. When I made
changes, the changes didn't reflected on the war files. Wierd. I will check
it out.

I fixed it using some quick and dirty tricks. I hard-code from 'cache.csv' t
o '/tmp/cache.csv'. Now it works fine.
But I still have problems generating the war file, I just replace the jar fi
le inside the deployed directory. Is there any book on how to manage large s
cale java code? Debuging using Eclipse and packing using maven is really tri
cky to me.
Thanks all

what i found to be the easiest way for me is to generate a stub war maven
project, and use the eclipse plug in to generate the project file for
eclipse.

It is tricky to package, debug, and deploy a large scale (many times, they
are modulized) web app in eclipse.
My experience is:
1. find one complete maven book
2. google some maven project samples.
3. pay attention to plugins.
