[xwiki-users] How to deploy Java Component and save files?
Hi users, My project in XWiki consists in a java component which offers some APIs through a script service called by a Velocity script in a wiki page. I put my .jar in the directory C:\XWiki Enterprise 7.3\*webapps\xwiki\WEB-INF\lib *and this is the Velocity and HTML code that I've put in my XWiki page: {{velocity}} #if("$!request.evolver" == 1) ## Request for creating a new instance $services.pars.parse() $services.evo.removeInstance("Take bike") $response.sendRedirect($xwiki.getURL('Main.WebHome')) ## Stop processing, since we already sent a redirect. #stop #end {{html}} <form action="" id="newEvolution" method="post"> <div> <input type="hidden" name="evolver" value="1"/> <span class="buttonwrapper"> <input type="submit" value="Evolve" class="button"/> </span> </div> </form> {{/html}} {{/velocity}} Let first say that nothing is happening when I click on the "Evolve" button and I don't know why...it looks like it should work, also because creating a Main_test class in Eclipse, I can run my software calling exactly the same methods and it works! Moreover my component must create some files to store some information, thus I am wondering where to save those files in order to make them accessible by the component. Any suggestions? Thanks in advance, Giordano.

You could use GET instead of POST and see what you get in the URL (ie whether you get the evolver=1 request param).
Moreover my component must create some files to store some information, thus I am wondering where to save those files in order to make them accessible by the component.
You can use the XWiki’s permanent directory. See http://extensions.xwiki.org/xwiki/bin/view/Extension/Environment+Module Thanks -Vincent
Any suggestions?
Thanks in advance, Giordano.
Dear Vincent, Tank you for your reply, I would try what you suggested in the afternoon, but regarding the "evolver=1 request param", I've set it equal to 1 together with POST command in order to make it always true ensuring that my component is started every time. My thoughts were wrong? Giordano. 2015-12-22 11:31 GMT+01:00 vincent@massol.net <vincent@massol.net>:

You said it didn’t work. You just need to debug what’s not working. First thing to check is whether you code inside "#if("$!request.evolver" == 1)” is called or not. Also I’d use an #else instead of #stop. Thanks -Vincent

Isn't the problem that it should be #if("$!request.evolver" == "1") And not #if("$!request.evolver" == 1) Ludo Le 22 déc. 2015 21:32, "Giordano Ninonà" <giordano.ninona@gmail.com> a écrit :

Hi users, Thanks for your answers, anyway it wasn't a String problem, and also change to GET doesn't produce anything. Maybe I've found my problem, when I start my component, the very first thing to do is to parse an XML file thus my script service provide a "parseBPXML()" method. The problem is where can i store this file in order to make accessible by my component, I've already Injected the Environment component but I can't understand where to put my file (i.e. which is the "permanent directory") and how to access it.

Thanks Vincent, I found everything I need but I got a nullpointer exeptioneverytime I use the *environment.getTemporaryDirectory() *method in my code.

If you’re deploying your component inside an XWiki you don’t need to initialize the CM, this is done for you by XWiki. A NPE means you’re missing an @Inject and thus the Environment instance is null. Could you show us your code? Thanks -Vincent
Any ideas why it is not working?

Hi Vincent, I've solved the "save files" problem with absolute paths and it works, however I've another problem, this time with the Velocity macro inside a wiki page. This is the exception that I've got: *org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate Velocity Macro for content [#if("$!request.evolver" == 1) ## Request for creating a new instance ##$services.evoS.parseBPXML('Home','BSS Rome') $services.evoS.removeInstance('Take bike') ##$response.sendRedirect($xwiki.getURL('Main.WebHome')) #else #end {{html}} <form action="" id="newEvolution" method="POST"> <div> <input type="hidden" name="evolver" value="1"/> <span class="buttonwrapper"> <input type="submit" value="Evolve" class="button"/> </span> </div> </form> {{/html}}] at org.xwiki.rendering.internal.macro.velocity.VelocityMacro.evaluateString(VelocityMacro.java:131) at org.xwiki.rendering.internal.macro.velocity.VelocityMacro.evaluateString(VelocityMacro.java:50) at org.xwiki.rendering.macro.script.AbstractScriptMacro.evaluateBlock(AbstractScriptMacro.java:286) at org.xwiki.rendering.macro.script.AbstractScriptMacro.execute(AbstractScriptMacro.java:182) at org.xwiki.rendering.macro.script.AbstractScriptMacro.execute(AbstractScriptMacro.java:58) at org.xwiki.rendering.internal.transformation.macro.MacroTransformation.transform(MacroTransformation.java:269) at org.xwiki.rendering.internal.transformation.DefaultRenderingContext.transformInContext(DefaultRenderingContext.java:183) at org.xwiki.rendering.internal.transformation.DefaultTransformationManager.performTransformations(DefaultTransformationManager.java:95) at org.xwiki.display.internal.DocumentContentDisplayer.display(DocumentContentDisplayer.java:253) at org.xwiki.display.internal.DocumentContentDisplayer.display(DocumentContentDisplayer.java:126) at org.xwiki.display.internal.DocumentContentDisplayer.display(DocumentContentDisplayer.java:56) at org.xwiki.display.internal.DefaultDocumentDisplayer.display(DefaultDocumentDisplayer.java:96) at org.xwiki.display.internal.DefaultDocumentDisplayer.display(DefaultDocumentDisplayer.java:39) at org.xwiki.sheet.internal.SheetDocumentDisplayer.display(SheetDocumentDisplayer.java:113) at org.xwiki.sheet.internal.SheetDocumentDisplayer.display(SheetDocumentDisplayer.java:50) at org.xwiki.display.internal.ConfiguredDocumentDisplayer.display(ConfiguredDocumentDisplayer.java:68) at org.xwiki.display.internal.ConfiguredDocumentDisplayer.display(ConfiguredDocumentDisplayer.java:42) at com.xpn.xwiki.doc.XWikiDocument.getRenderedContent(XWikiDocument.java:1164) at com.xpn.xwiki.doc.XWikiDocument.getRenderedContent(XWikiDocument.java:1127) at com.xpn.xwiki.doc.XWikiDocument.getRenderedContent(XWikiDocument.java:1179) at com.xpn.xwiki.api.Document.getRenderedContent(Document.java:692) at sun.reflect.GeneratedMethodAccessor403.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.velocity.util.introspection.UberspectImpl$VelMethodImpl.doInvoke(UberspectImpl.java:395) at org.apache.velocity.util.introspection.UberspectImpl$VelMethodImpl.invoke(UberspectImpl.java:384) at org.apache.velocity.runtime.parser.node.ASTMethod.execute(ASTMethod.java:173) at org.apache.velocity.runtime.parser.node.ASTReference.execute(ASTReference.java:280) at org.apache.velocity.runtime.parser.node.ASTReference.value(ASTReference.java:567) at org.apache.velocity.runtime.parser.node.ASTExpression.value(ASTExpression.java:71)* *...etc etc* You can find in the attachments the Tree structure of my wiki, pages inside "BSS Rome" space are all terminal pages.

If you’re deploying your component inside an XWiki you don’t need to initialize the CM, this is done for you by XWiki.
A NPE means you’re missing an @Inject and thus the Environment instance is null.
Could you show us your code?
Thanks -Vincent
Any ideas why it is not working?

Check your xwiki.properties file and search for permanentDirectory.

I thought so too but I tested and it works. I checked the Velocity documentation [1] and the explanation is:
"In the last case (when objects are of different classes), the toString() method is called on each object and the resulting Strings are compared."

Isn't the problem that it should be
#if("$!request.evolver" == "1")
And not
#if("$!request.evolver" == 1)
I thought so too but I tested and it works. I checked the Velocity documentation [1] and the explanation is:
"In the last case (when objects are of different classes), the toString() method is called on each object and the resulting Strings are compared."
Thanks, Marius

Dear Vincent,
Tank you for your reply, I would try what you suggested in the
afternoon,
but regarding the "evolver=1 request param", I've set it equal to 1 together with POST command in order to make it always true ensuring that my component is started every time. My thoughts were wrong?
Giordano.
