Alternatively, if you are using Tomcats hot deploy you are probably running
into the Tomcat memory leak. It's an ongoing problem that is still present
in the current 6.0.26 version. If you're developing in Eclipse then the
problem is probably being made worse by Eclipses default behaviour to
re-deploy after every change to the source. If this is the case then no
amount of adjusting your code as going to help you and no matter how much
memory you allocate to the JVM you are going to hit this at some point. The
only way around this is to periodically shut down and re-start Tomcat. 

The developers reckon that they've finally solved this in Tomcat 7 which is
currently in beta.

Struts 1 binding vulnerability

[Zheng, Xiahong]

Hi,

Spring recently released the following security vulnerability in its MVC data 
binding framework. Here is the description

The Spring Framework provides a mechanism to use client provided data to update 
the properties of an object. This mechanism allows an attacker to modify the 
properties of the class loader used to load the object (via 
'class.classloader'). This can lead to arbitrary command execution since, for 
example, an attacker can modify the URLs used by the class loader to point to 
locations controlled by the attacker.

For full description, follow this link 
http://www.springsource.com/security/cve-2010-1622

Although Struts is not vulnerable to the exact attack described in the cve, we 
found Struts' binding mechanism do expose the opportunities for an attacker to 
manipulate other classloader properties such as "delegationMode", "jarPath", 
"antiJarLocking", etc. I am wondering if the Struts team is aware of this and 
any plans to have a fix in the near future.

Thanks,
Xiaohong Zheng

I think the problem has to do with this line:

Hi,



Sorry if this is double posted, because I didn't receive the mail which I post.

I'm new to the struts2 rest plugin, I hope someone can help me.

I'm trying to post a json data to a UserController, I can see create method is 
invoked, but the json data is not set to the UserController.

Here is the json data:
{"user":{"userName":"TestUser","userEmail":"testu...@yahoo.com"}}

In my UserController, I've defined these getter/setter

public void setModel(UserBean bean)
public UserBean getModel()
public void setUser(UserBean bean)
public UserBean getUser()
public void  setUserName(String name)
public String getUserName()
public void setUserEmail(String email)
public String getUserEmail()

>From the log, I can c getModel(), validate(), create() are called, but no one 
setting anything to the controller.

Do I need to do extra thing to receive the json data?

The GET is working fine when I want to get some data from the UserController.

I've been searching the net pass 2 days, unfortunately most info are about GET, 
not POST or PUT.

I hope your guys can help me.

THanks

Re: convention plugin 2.1.8.1 and JBoss 5.1

[Scott Miller]

Yes,

The problem seems to be that struts 2 convention plugin is attempting  
to load the classes by loading files from the war file that is still  
inside the ear in the deploy directory of your jboss server.  This  
virtual file can't be loaded in the mechanism being provided by the  
convention plugin and therefore fails.


I am going to get around this by adding:

name="convention" class="com.myapp.MyPackageBasedActionConfigBuilder"/>


To struts.xml and extending the convention plugin provided  
ActionConfigBuilder.  My class will override the findActions method  
and then just include my action classes that I register manually.   
This is not ideal, but it will allow me to proceed and use the  
convention plugin without the automated discovery process.  If I have  
more time to dedicate to this later I will try and figure out a better  
way to actually handle the situation.  If so I will post the solution  
back to the list then.

validating integer, java.lang.NoSuchMethodException

[Jake Vang]

hi,

i am trying to validate an integer field (int primitive type) on a
POJO (i.e. MyPojo.integer). i have the validation defined in
--validation.xml as follows.

...

 
  Integer is required!
 

...

when the form posts to the action, if the value of  is left blank, i keep seeing a
java.lang.NoSuchMethodException:
MyPojo.setInteger([Ljava.lang.String;). why is struts trying to insert
a string into this int field?  the field value is "blank" (empty), so
i'd expect struts to be smart enough to see this and not try to insert
anything and just return back to the form with the validation error.

it should be very easy to define the following validation rules:
1. myPojo.integer is required
2. myPojo.integer is an integer

however, it is NOT that easy. here's a set of validation rules that i
tried and did not succeed.


 
 
  Integer is required!
 
 
 
  
  Please enter an integer!
 


when i use this set of validation rules, i also observe the same
NoSuchMethodException. this time, however, i do NOT see that the
validation works (because I do not see the message, Integer is
required!).

something like the following works, but STILL, i see the
NoSuchMethodException thrown if the field's value is left blank.
...

 1
 10
 Integer must be between ${min} and ${max}, current value is
${myPojo.integer}.

...

however, this last validation rule is absolutely the WORST one to use
because if the value on the form is left blank, 1) i will see the
NoSuchMethoException thrown and 2) if i allow for min=0 and max=10,
the validation will never know if the user entered 0 or was the 0
because there was no value!

any ideas is appreciated. i already experimented a lot and did not
come up with anything that is why this post is rather long.

thanks.

Re: validating integer, java.lang.NoSuchMethodException

[Jake Vang]

a workaround to this problem is to have a string field in the Action
class to represent MyPojo.integer. using this approach, the second set
of validation rules below work 100% and i no longer see the
NoSuchMethodException. however, the drawback is that now i have to
transfer this to my backing bean.

oh well, you win some, you lose some. if anyone has a better idea,
please let me know.

thanks.

 Use JConsole 
 or 
if you need more details a profiling tool like Yourkit

-XX:PermSize=64M -XX:MaxPermSize=128M, these parameters define
"PermGenSpace", this is where all class files are loaded.

Check out your Heap memory size. The PermGenSpace should be 1/4th of your
allocated Heap memory.

Vikram

You could also adjust your eclipse.ini to give more memory to the JVM:

-XX:PermSize=64M -XX:MaxPermSize=128M

Add it to the --vmargs section of the file.

Subject: [S2] post JSON to REST



Hi,



Sorry if this is double posted, because I didn't receive the mail which I post.

I'm new to the struts2 rest plugin, I hope someone can help me.

I'm trying to post a json data to a UserController, I can see create method is 
invoked, but the json data is not set to the UserController.

Here is the json data:
{"user":{"userName":"TestUser","userEmail":"testu...@yahoo.com"}}

In my UserController, I've defined these getter/setter

public void setModel(UserBean bean)
public UserBean getModel()
public void setUser(UserBean bean)
public UserBean getUser()
public void  setUserName(String name)
public String getUserName()
public void setUserEmail(String email)
public String getUserEmail()

From the log, I can c getModel(), validate(), create() are called, but no one 
setting anything to the controller.

Do I need to do extra thing to receive the json data?

The GET is working fine when I want to get some data from the UserController.

I've been searching the net pass 2 days, unfortunately most info are about GET, 
not POST or PUT.

I hope your guys can help me.

THanks

Created a struts2 application but getting odd results

[John L. Longo]

Here is the situation:

I'm using two separate browsers (IE8 & FF3.6) to test the application at the 
same time.

I have a form that takes contact information (name, address, email, etc.)

I access the form (http://localhost:9084/demosite/contactus.action) from IE8 
and type the first name and hit the submit button.

The validation fails and the page is displayed with the first Name still filled 
in and the correct error messages displayed (Last Name Required, etc.).

BTW, That's is what I expected.

But here is the odd problem that I'm seeing:

I then open up FF3.6 and enter the URL 
http://localhost:9084/demosite/contactus.action

I see the page displayed with the same info (First Name filled in and error 
messages displayed) that I have in the IE8 browser.

I'm using struts2-core-2.1.8.1 and running it under Websphere 7.0.0.9.

I'm sure I have a setup issue, but really don't know what it could be, other 
than that the application is working fine no error messages in the logs.
