I have tried to customise the Switch java plugin sample by giving it a new name and adding some properties and renaming the trace properties
On the basis that the user guide says to add the two methods
| Code: |
private String attributeVariable;
public String getFirstAttribute()
{
return attributeVariable;
}
public void setFirstAttribute(String value)
{
attributeVariable = value;
}
|
which defines a variable firstAttribute, I have created a series of properties, leading lower case in msgnode file upper case in java source
I get the following error on deploy but cannot work out where the fault lies, in the node definition or the java source
Any ideas ??
| Code: |
BIP2210e: Invalid configuration message: attribute name 'className' not valid for target object 'RunSampleCallEJB.'.
The message broker received a configuration message containing the attribute name 'className' which is not valid for the target object 'RunSampleCallEJB.'. This can be caused by a mismatch in levels between the Message Brokers Toolkit, the Configuration Manager and the Broker, or as a result of a user or third party written plug-in node where the implementation library installed at the broker does not match the node definition held at the Configuration manager and Message Brokers Toolkit.
Ensure that the levels of code installed at the Message Brokers Toolkit, Configuration Manager and Broker are all consistent. If they are, identify the supplier of the target object and report the problem to them. If this is IBM, contact your IBM support center.

Try using ejbClassName instead of className for your parameter.

Thanks for the suggestion. On what basis did you make the suggestion, it appears to be a simple change of characters?
I did make the change and then for check changed it to nodeClassName and made progress, however it just came up with the same error on a different attribute. I removed attributes until it worked (leaving renamed attributes nodeHostName, nodeClassName, nodePort, nodeTraceLevel and nodeTraceFile)
I then added one more attribute (nodeAnotherName) and this was rejected and I cannot see why?
No matter what I do to the names of the offending attribute, it does want to accept it.
in nodename.properties
I suppose I am just very unclear on what WBIMB is actually expecting in terms on names in *msgnode, *.properties, names in java, including must do must not do or whether there is something else that I have totally missed, these messages being a bit if red herring maybe. It does not seem intuitive or logical.
Each time I change the node I update the classpath for the project in toolkit, export to zip, unzip to root\eclipse\plugins, stop toolkit, configmgr, borker and restart, am I missing something
Are there any other examples, other than Switch/Transform using additional / renamed parameters that might help me to understand
Details
| Code: |
Property.nodeAnotherName=nodeAnotherName
|
java
| Code: |
public String getNodeAnotherName()
{
return _nodeAnotherName;
}
public void setNodeAnotherName(String valueAnotherName)
{
_nodeAnotherName = valueAnotherName;
if(traceWriter != null) {
traceWriter.println("Attribute AnotherName set to: " + _nodeAnotherName);
}
}
|
giving error
| Code: |
Invalid configuration message: attribute name 'nodeAnotherName' not valid for target object 'RunSampleCallEJB.CallEJB'.
|
Given that this is virtually identical to the definition for nodeClassName!
| Code: |
Property.nodeClassName=Class Name
public String getNodeClassName()
{
return _nodeClassName;
}
public void setNodeClassName(String valueClassName)
{
_nodeClassName = valueClassName;
if(traceWriter != null) {
traceWriter.println("Attribute ClassName set to: " + _nodeClassName);
}
}

For the recordI think I have solved this.
There was an older .jar file in the wbimb_root\bin directory which when removed allowed the plugin to start working more consistently.
Though I don't understand why this was being used as it was not in my %CLASSPATH%, unless WBIMB puts it there ?? |
