Hi Tika users.
I'm having trouble importing tika .class files. I have written a basic
.java script that is saved in the same directory as toolsUI-4.3.jar .
I call the script at the command line as:
[abryant:~/tika/tika] abryant% javac -cp '.:toolsUI-4.3.jar'
NetDump_tikalist.java
Within that script I have the import commands:
import org.apache.tika.metadata.Metadata;
import org.apache.tika.metadata.Property;
Once I execute the script I get the errors:
NetDump_tikalist.java:11: package org.apache.tika.metadata does not
exist
import org.apache.tika.metadata.Metadata;
^
NetDump_tikalist.java:12: package org.apache.tika.metadata does not
exist
import org.apache.tika.metadata.Property;
The 'metadata' files are in:
/Users/annbryant/tika/tika/tika-core/target/classes/org/apache/tika/metadata
If I run the script with the two tika import commands commented out, it
works fine.
As a java beginner I'd appreciate any input on the behind-the-scenes action
that needs to take place to have scripts find tika .class files.
Many thanks!
Annie
