File Adapter giving Translation error while reading & moving pdf files

Question

Hello Gurus,
I am on SOA 10.1.3.4 and using BPEL for the below procedure.
The requirement I have is to move pdf files from one local directory to another as soon as the pdf files land in source directory. So I used a file adapter (FileAdapter_1) to poll the file and read as an opaque schema. Then I copied the name and directory in a header variable and passed the header variable to another file adapter(FileAdapter_2) which moves the file from source to target directory. The jca operation for FileAdapter_2 is as follows:
<jca:operation
InteractionSpec="oracle.tip.adapter.file.outbound.FileIoInteractionSpec"
SourcePhysicalDirectory="foo1"
SourceFileName="bar1"
TargetPhysicalDirectory="foo2"
TargetFileName="bar2"
Type="MOVE">
</jca:operation>
It is working fine for all 90% of pdf files, but some files are failing with the following error in domain.log file.

Error while translating.
[Line=1, Col=5] The value "%PDF" read from the native data, from the specified position, using "choiceCondition" as "fixedLength" and "length" as "4", doesnt match any of the "conditionValue" on the particles of choice model group.
Check the error stack and fix the cause of the error. Contact oracle support if error is not fixable.

Thanks in advance for your help.......

Answer 1

As stated in my Original Post, I am using opaque schema for both the adapters, still not sure why the adapter is going through native translation.
