how to start

[axelrose]

Hello all,

I was just curious and tried to check an example.

withMacOS X 10.5.5
This command line:

/System/Library/Frameworks/JavaVM.framework//Versions/1.6.0/Home/bin/
java -cp gxp-0.2.3-beta.jar com.google.gxp.compiler.cli.Gxpc --verbose
gxp-read-only/java/test/com/google/gxp/compiler/functests/
SomeTagsGxp.gxp

doesn't seem to result in any output.

By accident I tried this:

/System/Library/Frameworks/JavaVM.framework//Versions/1.6.0/Home/bin/
java -cp gxp-0.2.3-beta.jar com.google.gxp.compiler.cli.Gxpc --verbose
foo gxp-read-only/java/test/com/google/gxp/compiler/functests/
SomeTagsGxp.gxp
java.lang.NullPointerException

You need --source gxp-read-only/java/test to specify the base
directory of your source gxps.

And ya, we know it should give you an error explaining this instead of
NPEing. I'll work on this sort of thing someday (it's a relatively
low priority though).

Thanks for your response, Harry!

I still seem to have something missing:

export PATH=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/
Home/bin:$PATH
export JAVA_HOME=//System/Library/Frameworks/JavaVM.framework/Versions/
1.6.0/Home

java -cp gxp-0.2.3-beta.jar com.google.gxp.compiler.cli.Gxpc --
verbose --source gxp-read-only/java/test gxp-read-only/java/test/com/
google/gxp/compiler/functests/SomeTagsGxp.gxp

still doesn't see to have any effect. What should I see where?


I tried to track this down with Eclipse.

ant test
...
[junit] OK (554 tests)

Now import a new project from existing source.
Eclipse 3.3.2 shows 21 errors, all of this type:

The method iterator() of type BaseMessage must override a superclass
method gxp/java/src/com/google/transconsole/common/messages
BaseMessage.java line 101 1222627964496 248017


Any idea?


Thanks

You'll also want to add --output_language java to tell gxpc you want
to generate .java files. And if you are using i18n features, you'll
need --message_source to specify a location for your message
resources to live and --output_properties to output a properties file.

java -cp gxp-0.2.3-beta.jar com.google.gxp.compiler.cli.Gxpc --

verbose --output_language java --source gxp-read-only/java/test gxp-

Now new output seems to have been generated.
