[JET] writing into files [message #489320]

I want to write into one file from different templates. The file will be created with the main-template. While executing I get the ResourceException: "A resource exists with a different case:..."

For example let's consider a model
<app name = "Hello">
<person name = "A">
<property name="a"></property>
</person>
<person name = "B">
<property name="b"></property>
</person>
<person name = "C">
<property name="c"></property>
</person>
</app>

Creating a file in the main-template for every "person" with the personname works. But when I try to write properties into a Person's file with a property-template I get that error.

Template-Structure:
main
person
property

Any ideas?

Thanks for them,
Siegfried

Siegfried:

Two suggestions:

1) The 'ResourceException' message is indicating that you are trying to write a file whose name is identical to an existing file, except for case. E.g. you are writing Foo.txt, but foo.txt already exists.

Check the names you are specifying in the 'path' attribute of ws:file

2) I am guessing your approach is something like:

<ws:file path=".../Foo.txt" template="templateA.jet"/>
<ws:file path=".../Foo.txt" template="templateB.jet"/>

An you are hoping the Foo.txt will contain the concatenation of templates A and B. It will not. Instead, it will contain only the results of templateB - JET does no support appending to a file.

Instead, I suggest writing the file only once:

<ws:file path=".../Foo.txt template="combined.jet"/>

with combined.jet doing:

<c:include template="templateA.jet"/>
<c:include template="templateB.jet"/>

Hello Paul,

I know, I'm a bit late with it, but thank you for your help. Indeed I tried to write into one foo.txt from two different templates. I won't do it again.

Kind regards,
Siegfried
