Prevent accidental manipulation of ColdFusion session cookies

In ColdFusion 9.0.2 and earlier, people needed to modify ColdFusion session cookies for adding additional cookie attributes. With ColdFusion 10, this is no longer required. (For details see here). 

So now while migrating to ColdFusion 10, this code needs to be updated. Let's see the scenario when this code is left out. The behavior is unknown. To avoid this, ColdFusion 10 comes with another setting - 

Settings -> Memory Variables -> Session Cookie Settings -> Disable updating ColdFusion internal cookies using ColdFusion tags/functions

It can also be set using Application.cfm/cfc. See this entry for details.

When enabled this will prevent CFCookie and CFHeader tags to update ColdFusion session and authorization cookies.

There is one more enhancement done for cfcookie/cfheader - In previous versions, cookie value was always encoded. However this might cause issues with a cookie value expected with some extra characters. Now you can use new attribute "preservecase" and "encodevalue" for CFCookie tag and "encoded" attribute for CFHeader tag when type=cookie.

ColdFusion 10 & Image Enhancements

With ColdFusion 10 there are some image enhancements done. Here is a list of those enhancements -

1. Image Resize and interpolation: With ImageResize and ImageScaleToFit , interpolation is one of the parameters. This Interpolation argument control quality of resultant image. This has an impact on performance.  Higher the quality, slower the response time will be. Possible value for this argument are  highestQuality (default), highQuality, mediumQuality, highestPerformance, highPerformance, mediumPerformance, nearest, bilinear, bicubic, bessel, blackman, hamming, hanning, hermite, lanczos, mitchell, quadratic.  

With ColdFusion 10, this support is added in cfimage tag as well. Now for cfimage action="resize", interpolation is one of the possible attribute.  Default value is kept in sync with the function equivalents of this action.

2. ImageDrawText: ImageDrawText method will now return a struct containing the width of the text drawn and the height of the text drawn.

3. CMYK Image support: CMYK Images were not working for Mac and 64bit OS. we have added support for the same.

4. Fixed a bug in ImageGrayScale with TiFF images.

5. Captcha Creation: ImageCreateCaptcha method support is added. 
      ImageCreateCaptcha(int height, int width, String text)
      ImageCreateCaptcha(int height, int width, String text, String difficulty)
      ImageCreateCaptcha(int height, int width, String text, String difficulty, String fonts,  int fontSize)

6, Change in behavior for action="captcha":  Added name attribute to action="captcha" for cfimage tag. This new attribute name will contain the image variable object.Now inline captcha will be rendered only when name and destination are not specified. Else if name is specified, image will be saved in variable like other image functions. If destination is specified, captcha image will be saved at the location mentioned.

7. For cfimage action = "captcha", if user specified font is not found, it will fall back to system fonts

8. ImageMakeColorTransparent: New method ImageMakeColorTransparent  is added. This will create an image and set a transparent color

9. ImageMakeTranslucent: New method  ImageMakeTranslucent  is added. This will create a new translucent imagewith given percentage of translucence
     ImageMakeTranslucent (imgpercent)

10. New Parameters for ImageOverlay: New parameters rule and alpha are added for the function ImageOverlay.
     ImageOverlay(source1, source2, [rule, alpha]))

For detailed information on all these APIs refer to ColdFusion 10 documentation.

If you see memory leak you can explore using memory leak fix done by Jpedal for JAI. You can read about it and download from here.

WebSphere & Cookie Expires Format

On IBM Websphere 7.0 all session cookie related test cases might fail. This happens because of the following bug in Websphere 

Here are some details : 
Based on RFCs, the cookie expire date format is  DD-Mon-YYYY HH:MM:SS GMT. (RFC 822RFC 850RFC 1036, and RFC 1123)

But in WebSphere 7 it comes as  DD-Mon-YY HH:MM:SS GMT

So on the browsers which doesn't recognize this expire date format, ColdFusion administrator and other session related stuffs (which uses session cookies) may break.

Troubleshooting with JBoss 7

Recently I coming across a lot of configurations that are required for new servers like JBoss 6 & 7. So I thought of jotting them at a single place. I may be mentioning them in brief sometimes and sometimes I would provide as much detail as I can.

  • JBoss & Cookie Expiry : With JBoss 6 and 7, cookies by default specify the expiration time of cookie as "Max-Age" header attribute instead of "Expires". I have written a detail about this here.
  • Random number generation and server start up is slow on Unix platforms for some of the servers. This is because of /dev/random is used in Unix platforms for random number generation. I have added a detail entry explaining the problem and solution here.
  • JBoss 7 AS, has modular class loading. It provides true application isolation, hiding server implementation classes from application and only loading the classes your application needs. Modules, packaged as collections of classes, are peers that remain isolated unless explicitly defined as a dependency of another module. These visibility rules  can be customized. 

    Due to this design, JBoss modules does not load everything from rt.jar and many other system jars by default. As a result you may get ClassNotFoundException or NoClassDefFounfError for a lot of classes. Read here for solution and workarounds available for this.
  • When running Jsafe library on JBoss, if you get error like java.lang.NoClassDefFoundError put the jsafe (CryptoJ) jars to <JAVA_HOME>/jre/lib/ext directory. This mostly occurs on Unix platforms.
  • In JBoss version 7 or above if open office is not working start JBoss with flag -Djava.ext.dirs=<jboss-deployment-dir>/cfusion.ear/cfusion.war/WEB-INF/cfusion/lib/oosdk/:<java-home>/lib/ext/ .

I will keep updating this space as and when i will find more.

JBoss 7 & Sandbox

JBoss 7 AS, has modular class loading. It provides true application isolation, hiding server implementation classes from application and only loading the classes your application needs. Modules, packaged as collections of classes, are peers that remain isolated unless explicitly defined as a dependency of another module. These visibility rules  can be customized. 

Due to this design, JBoss modules does not load everything from rt.jar and many other system jars by default. As a result you may get ClassNotFoundException or NoClassDefFounfError for a lot of classes. 

Open Office, web services tests might fail

Solution: jboss-deployment-structure.xml  -

To Fix this the solution is to, use a jboss-deployment-structure.xml in your war as explained here https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7


<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
         <module name="deployment.system"/>
    <module name="deployment.system">
         <system export="true">
                 <path name="com/sun/net/ssl/internal/ssl"/>

However if for some reason you can't add jboss-deployment-structure.xml quickly in your application following are 2 workarounds.

Workarounds 1: For JRE System classes, There is a modue named "sun.jdk" that depdends on module "system". Here are defined all packages jboss loads from rt.jar.

In this module.xml of /sun/jdk/main directory add the required packages as -
                        <path name="com/sun/imageio/spi"/>
                        <path name="javax/annotation/processing"/>
etc, according to the need of application.

<module xmlns="urn:jboss:module:1.0" name="sun.jdk">
        <resource-root path="service-loader-resources"/>
        <module name="system" export="false" services="import">

                    <!-- extra packages -->
                    <path name="javax/annotation/processing"/>

                    <path name="com/sun/script/javascript"/>
                    <path name="com/sun/imageio/spi"/>
                    <path name="com/sun/jndi/dns"/>
                    <path name="com/sun/jndi/ldap"/>
                    <path name="com/sun/security/auth"/>
                    <path name="com/sun/security/auth/module"/>
                    <path name="sun/misc"/>
                    <path name="sun/nio"/>
                    <path name="sun/nio/ch"/>
                    <path name="sun/util"/>
                    <path name="sun/util/calendar"/>
                    <path name="META-INF/services"/>

Workaround 2:

Add jboss.modules.system.pkgs system property with comma separated list of packages to load. 


Additional Information:

Related issues - 

JBoss cfusion.ear/war deployment timeout:

If cfusion.ear is not deployed within the deployment timeout for jboss you can change the deployment timeout of jboss in standalone.xml
<subsystem xmlns="urn:jboss:domain:deployment-scanner:1.0">
   <deployment-scanner scan-interval="5000"
      relative-to="jboss.server.base.dir" path="deployments"   deployment-timeout=”120”,/>


Performance tuning is an important part any application development.  In order to use JProfiler ofor jboss 7, first you need to add the following to your standalone.conf file:

JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=com.jprofiler -agentlib:jprofilerti -Xbootclasspath/a:/path/to/jprofiler/bin/agent.jar"

The "jboss.modules.system.pkgs" property tells JBoss Modules to allow the "com.profiler" classes to be found from any class loader, which is essential to allow the JProfiler agent to run. It is easier to then just set up your jprofiler sessio nas "Remote", and start the server and profiler.
