Hi,
I assume you are using Message Broker version 7?
We have the same issue on our upgraded servers.
(It works fine on version 6.1 servers)
I have noticed that the classes used aren't the ones from the activation.jar but from the system library jar rt.jar. (package=javax.activation).
My question is: Is there a prefered way to make sure that the activation.jar classes are used? You only wants this for this flow.

So at least in v7.0.0.1, you can take some additional customization steps on this supportPac that will provide some relieve.
If I recall correctly, this supportPac is currently shipped as a subflow that contains two JavaCompute nodes. You can create a JavaClassLoader Configurable Service that specifies a directory for the IA9R jar files, and specify that the two JavaCompute nodes in the subflow should use this classloader.
But you should contact the author of this SupportPac directly for support. |

The code works fine in a stand alone java application.
The problem is with system library jars having the same classes and the classloading sequence in Broker 7.
I have tried to create a configurable service like this:
| Code: |
mqsicreateconfigurableservice FTFXPUTV_BRK -c JavaClassLoader -o pop3ClassLoader -n includedDeployedJars -v "activation.jar;mail.jar"
|
And add "pop3ClassLoader" to the java node config.
When I deploy, I get the following error:
| Code: |
Message: BIP4500E
Source: Runtime Response
Creation time: Thu Nov 18 16:38:06 CET 2010
BIP4500E: Failed to deploy Java code resource 'JAR'. The Java stack trace is: 'Frame : 0 java.lang.NoClassDefFoundError: javax.mail.Part
@: java.lang.J9VMInternals.verifyImpl(Na... (data of len 2622 truncated)'
The Java JAR file deployment to the broker failed.
This is an internal error. Contact your IBM support center.
|
And of course, the javax.mail.Part is in the jars specified.
I made a final attempt to change the JavaClassLoader service:
| Code: |
mqsichangeproperties FTFXPUTV_BRK -c JavaClassLoader -o pop3ClassLoader -n sharedJarPath -v c:/tmp/pop3classes
|
..and copy the jars to that directory instead, but that also failed.
I know this is not supported by IBM, but has anyone been able to get multipart emails to parse as MimeMultipart objects, please let me know.
Also, if any kind soul out there could come up with an (general)explanation to how the classloading works (to help me understand how to avoid the error displayed above) it would be greatly appreciated.
Kind Regards,
contact admin

Hi,
I still can't get it working.
Quote from http://publib.boulder.ibm.com/infocenter/wmbhelp/v7r0m0/index.jsp?topic=/com.ibm.etools.mft.doc/ac37125_.htm
| Quote: |
| When you include one or more JavaCompute nodes in a broker archive (BAR) file, the JAR files are loaded in a separate classloader. The classloader loads all classes that are packaged in the deployed BAR file. These classes override any classes that are in the shared classes directory or the CLASSPATH environment variable. |
Doesn't it mean tt if the .jar file is in the deployed BAR file, it should be using that instead?
Anyway I tried using configurableservice, it still does not work.
I created:
| Code: |
mqsicreateconfigurableservice TESTQMBROKER -c JavaClassLoader -o pop3ClassLoader -n includedDeployedJars -v "d:\workspace\IA9RJava\activation.jar;d:\workspace\IA9RJava\mail.jar"
|
and add it to the java compute node java classloader service property.
the error i got when deploying is:
java.lang.classNotFoundException.
Any help appreciated. thanks |

Hi mqjeff! (and others) :-)
Config1:
| Code: |
mqsireportproperties FTFXPUTV_BRK -c JavaClassLoader -o AllReportableEntityNames -r
JavaClassLoader
Template
includedDeployedJars='automatic'
sharedJarPath=''
pop3ClassLoader
includedDeployedJars='activation.jar;mail.jar'
sharedJarPath='' |
In this configuration I made three tests:
1) activation.jar and mail.jar in bar file
2) activation.jar and mail.jar predeployed to the exec group
3) activation.jar and mail.jar predeployed *and* in bar file
Config2:
| Code: |
mqsireportproperties FTFXPUTV_BRK -c JavaClassLoader -o AllReportableEntityNames -r
JavaClassLoader
Template
includedDeployedJars='automatic'
sharedJarPath=''
pop3ClassLoader
includedDeployedJars='activation.jar;mail.jar'
sharedJarPath='c:/tmp/pop3classes' |
In this configuration I made one test: bars only in the shared jar path
Config3 (as suggested by mqjeff):
| Code: |
mqsireportproperties FTFXPUTV_BRK -c JavaClassLoader -o AllReportableEntityNames -r
JavaClassLoader
Template
includedDeployedJars='automatic'
sharedJarPath=''
pop3ClassLoader
includedDeployedJars='automatic'
sharedJarPath='c:/tmp/pop3classes' |
in this configuration I also only made one test, with jar fies in shared jar path only.
All fails with this error:
| Code: |
BIP4500E: Failed to deploy Java code resource 'JAR'. The Java stack trace is: 'Frame : 0 java.lang.NoClassDefFoundError: javax.mail.Part
@: java.lang.J9VMInternals.verifyImpl(Na... (data of len 2242 truncated)'
The Java JAR file deployment to the broker failed.
This is an internal error. Contact your IBM support center.
|
(and yes, i have tried both forward and backward slashes in the path)
To make sure I understood the functionality, I finally made som simple HelloWorld tests to verify that classes could be loaded from a sharedJarPath, and they worked fine.

Hi,
I got it working. All thanks to the author of the code, Wang Chao.
| Quote: |
| It's a known issue. The JAF jar files are included in WMB7's new JRE 1.6.x(http://www.roseindia.net/javamail/Introduction-to-Java-Mail-API.shtml). Therefore the JAF and JavaMail jar files are in different class loader. Placing both mail.jar and activation.jar to the jre/lib/ext directory should be able to resolve the issue. Let me know if the problem persists. |
just put both the .jar file in the MQSI \7.0\jre16\lib\ext folder.
Thanks all for the help. =)
Cheers. |

Please don't reopen three year old threads like this. It is better to start a new one and reference the old one.
Please let us know what version of Broker (x.x.x.x format) you are developing for. In later versions there are builtin nodes that make this support pack redundant.
The Support Pack has not been updated since 2008 and was developed for Broker V6, V6.1 both of which are out of support now.
The 'fix' for V7 was a hack and not one I'd ever consider putting into production.
