The type "Date" was not found: How to resolve this issue?

I am a java developer but new to Modelio.
I installed Modelio 3.5 on Windows 7 with modules "Java Designer", "Modeler Modules", "Persistent Profile", etc.
I am primarily interested in the "RoundTrip" code generation mode, as I am attaching a screenshot here.

My case is, if I create a java class diagram, and do a code generation, I get ABC.java.
Then I manually insert an attribute and a method in this java file, say,

public testMethod(String tableName, String columnName) {

}
public Date thisDate = null;

and click "Update Model from source if necessary", I want to see the model to show this method and attribute (that is "RoundTrip", right?), but Modelio does not understand the the java type "Date" and "String", for example, I got this warning:

The type "Date" was not found.
A "JavaTypeExpr" tagged value was generated for this type.

and the class model displays: thisDate: <no type>

I read some posts online and I was told I need to do some model-type and java-type mapping in the "javaCustomizationFile.xml". Here is my addins:

<ModelType name="date">
<JavaType name="Date">
<import name="java.util.Date"/>
<wrapper name="Date"/>
</JavaType>
</ModelType>
<ModelType name="string">
<JavaType name="String">
<import name="java.lang.String"/>
<wrapper name="String"/>
</JavaType>
</ModelType>

I found 3 javaCustomizationFile.xml in my machine, I am not sure which one is effective, so I added the above block to all of them, and restart the modelio. However, I am still having the same problem. The above xml-file block seems not effective.

Did I miss anything? Please help.

Hi,

The mapping between Java types (String for example) and Modelio primitive types (string) is done by default.
You should check two things.
1) The JDK Path in the JavaDesigner module parameters

2) The accessible classes



Hoping it helps,

Thank you ebr for my late reply...
I was using Modelio 3.5, I can not follow your steps because I do not have "Java Designer by Modeliosoft". I guess it requires a paid license. Of course I believe I have the right JDK and rt.jar, etc, configured, but I always have the problem for "Round Trip".

However recently I installed Modelio 3.6. I exported by project from Modelio 3.5 and import it to the new version.and this problem seems gone! For example, in the modeled class ABC.java if I have an attribute java.io.Serializable mySer, I generate the code and do some code modification via eclipse, then I tried "Update model from sources if neccessary", I got no errors and no warnings!

Thank you for your detailed explanation anyway,
best wishes
