solr-web 5.2.01 does not work with liferay 5.2.3

[Tobias Rübner, modificado hace 14 años.]

Hello,

I think the implementation of the solr-web plugin v5.2.0.1 is broken with the new release of liferay.
It worked perfectly with liferay 5.2.2 (but this version does not work with LDAP) and now we are getting a NullPointerException when trying to search with the search-portlet.
I double checked this behavior with a clean liferay-portal-5.2.3-tomcat-6.0.18 version. Just installed the solr.war and deployed the solr-web plugin.
Does anyone have the same issue or a workaround?

Does no one have the same error?

[Bruno Farache, modificado hace 14 años.]

This was fixed by

http://issues.liferay.com/browse/LPS-2885

Plugins compatible with 5.2.3 weren't released yet, but I think we are close to releasing them.

[Denis Signoretto, modificado hace 14 años.]

Hi Burno, do you know if the solr-web plugin for 5.2.3 is ready?
I also need to know wich version of solr it support (1.2 or 1.3)?

Thanks,
Denis.

[Ken Horn, modificado hace 14 años.]

Hi,

Is the new Solr-Web plugin ready for release?
Thank you.

[Camilo Aguilar, modificado hace 14 años.]

I have the same issue, any updates ?

Anybody can help me please ?

[Anderson Souza, modificado hace 14 años.]

I was having problem with this issue too, and after I saw this thread I decided to work on the code to correct the problem.
The steps executed to create a working code for liferay 5.2.3 were:

1- get the latest plugin code from svn (http://svn.liferay.com/repos/public/plugins/branches/5.2.x/webs/solr-web)
2- add missing classes (messaging classes and SolrSearchEngineUtil) using classes avalable on released plugin (http://downloads.sourceforge.net/lportal/solr-web-5.2.0.1.war)
3- add missing import for com.liferay.portal.kernel.search.SearchEngineUtil on SolrSearchEngineImpl
4- add missing methods init(), isRegistered(), register() and unregister(), on SolrSearchEngineImpl
5- add missing attributes _name and _registered on SolrSearchEngineImpl
6- remove _indexReadOnly and isIndexReadOnly method from SolrSearchEngineImpl
7- remove method isIndexReadOnly() on SolrSearchEngineUtil
8- remove method doCommandIndexOnly() and the "if (command.equals(SearchRequest.COMMAND_INDEX_ONLY))" test existing on SolrReaderMessageListener.
9- use solr-spring.xml from downloaded plugin and comment the properties "name" and "indexReadOnly" for bean "searchEngineUtil".

My solr-spring.xml look like this:

<!--?xml version="1.0" encoding="UTF-8"?-->
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

	<bean id="messageListener.solr_writer" class="com.liferay.portal.search.solr.messaging.SolrWriterMessageListener" />
	<bean id="messagingConfigurator" class="com.liferay.portal.kernel.messaging.config.PluginMessagingConfigurator" depends-on="searchEngineUtil" init-method="init" destroy-method="destroy">
		<property name="messageListeners">
			<map key-type="java.lang.String" value-type="java.util.List">

					<list value-type="com.liferay.portal.kernel.messaging.MessageListener">
						<ref bean="messageListener.solr_reader" />
					</list>
				</entry>
				<entry key="liferay/search_writer">

						<ref bean="messageListener.solr_writer" />
					</list>
				</entry>
			</map>
		</property>
	</bean>
</beans>

This worked fine for me.
The eclipse project with obtained code is attached on this post.

Good job! Thank you, Anderson, to share fixes.

The downloading (solr-web.zip) is very slow .... even it is unreachable ... but got it finally.

Great job Anderson, thanks !

I have all these settings in 5.2.3 community edition and it does not work for me, but,
when I got Liferay EE 5.2.5 this issue disappeared mysteriously...

[Igor Barma, modificado hace 14 años.]

Hi,
Is anyone have more informations about a release of SOLR-Web pluggin fully fonctionnal with liferay 5.2.3.
Thanks
Igor

[Carlos del Castillo, modificado hace 14 años.]

Thanks Anderson for sharing this.

I tried this on liferay 5.2.3 but did not work. When deploying the plugin I get the following error:

17:32:55,180 ERROR [ContextLoader:215] Context initialization failed
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class 
[com.liferay.portal.search.solr.server.BasicAuthSolrServer] for bean with name 'solrServer' 
defined in ServletContext resource [/WEB-INF/classes/META-INF/solr-spring.xml]; 
nested exception is java.lang.ClassNotFoundException: 
com.liferay.portal.search.solr.server.BasicAuthSolrServer

Any ideas?

Thanks!

[Darren Govoni, modificado hace 14 años.]

Has anyone gotten solr-web 5.2.01 to work with LR 5.2.3 yet? If so, can you post the .war please?
I tried the .zip above, but it doesn't work. LR doesn't seem to recognize the plugin.

thanks!!

[Albert J Carter-Corbin, modificado hace 14 años.]

I think I was able to get Solr-Web branch svn (12/18/09) to work with the liferay branch svn (12/18/09) by modifying the SolrIndexSearcherIndex.java code with the following:

I changed the following:

solrQuery.setQuery(query.toString());


To the following:

String queryStr = query.toString();
while( queryStr.indexOf( ":*") > -1 ) {
String str1 = queryStr.substring( 0, queryStr.indexOf( ":*") +1 );
String str2 = queryStr.substring( queryStr.indexOf( ":*") + 2 );
queryStr = str1 + str2;
}
solrQuery.setQuery(queryStr);

solr doesn't like the '*' character to begin a keyword search.

Yes, it seems the zip-file is incomplete; what I did was checking out the branch source (user "guest", no password) then adding his changes to that as a patch then building in the plugin SDK.

[Darren Govoni, modificado hace 14 años.]

Hey guys. Could one of you kind folk mind posting the modified .class or .war for this patch please?

Many thanks!!

[Madhu Yadav, modificado hace 14 años.]

I have attached the patched .war file to this post. Its working for liferay 5.2.3,tomcat 6.0.18 and solr 1.4.0

I followed previous posts in this thread here but in the order as mentioned here.
The only modifications to those steps:

• Updated xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" in solr-spring.xml
• And in the same file,kept the arg for solrServer bean by default as http://localhost:8080/solr

[Madhu Yadav, modificado hace 14 años.]

Has anyone tried displaying search results which are not liferay web content items but something else which was indexed..i.e a file system or afresco repo etc?

[Mike Davis, modificado hace 14 años.]

Is this solr-web-5.2.3.1.war only for Tomcat 6.0.18? I'm trying to deploy to JBoss 5.1 and not having any luck.

[Madhu Yadav, modificado hace 14 años.]

shouldn't matter..anything different in logs?

[Rastislav Papp, modificado hace 14 años.]

hi, I've managed to get the 5.2.3.1 plugin to work, but everytime I start the Liferay server, Solr starts doing this:

......

......

and it goes on and on for like 10 minutes.

Also when it finishes, I'm able to search in the portal using Solr, but for the search string 'a' it throws an exception:

org.apache.solr.common.SolrException: Bad Request

Bad Request

request: http://localhost:8081/solr/select?q=+(+portletId:36) +(() () ())&fl=score&start=0&rows=5&sort=score asc,modified desc&wt=javabin&version=2.2

[Madhu Yadav, modificado hace 14 años.]

What you see in the logs is that solr is indexing liferay content..
While for the bad request error:
1. what is the output on the screen - search results??
2. is this error only for the string 'a'?
3. a longer stacktrace to this??

[Vanita Chawla, modificado hace 13 años.]

Thanks to everyone's help on this post, I have Solr working with 5.2.3 on Tomcat 5.5.

I do get an error when searching for Users with advanced search on screen name and other attributes. I am importing users from LDAP.

Any help is much appreciated.

The stack trace is:

I am trying to install solar-web 5.2.3.1 or 5.2.0.1 with Liferay 6.0.1. However, I have method not found error since the unregister method in com.liferay.portal.kernel.search.SearchEngineUtil class (liferay 5.2.3) is not there any more.
Have anyone tried solr with 6.0.1?

Brian Ko

[Brian Ko, modificado hace 13 años.]

Please disregard my previous posting. I found there is an wiki about that subject. (I was supposed to use solr-web 6.0.1 or 6.1.1)

http://www.liferay.com/community/wiki/-/wiki/Main/Integrate%20Solr%20with%20Liferay%20portal

Brian Ko

[Vanita Chawla, modificado hace 13 años.]

I see this issue was already reported below:

http://issues.liferay.com/browse/LPS-3120

Does anyone know which version is this fix in? It is not clear from what I see.

Thanks for all your help!

[Brian Ko, modificado hace 13 años.]

I found solr 5.2.3 was not working with liferay 6.0.1 as the API was changed on Liferay. When I installed solr-web 6.0.1, it worked. Therefore, I suggest you to try solr-web-5.2.3.1.war. I do not remember the download site, but you can find that version somewhere on the web.

Brian Ko

[Vanita Chawla, modificado hace 13 años.]

Thanks Brian. I am using Liferay 5.2.3 with solr-web-5.2.3.1.war and still running into an issue.

[Sriram Gopalan, modificado hace 13 años.]

I was using 5.2.3 with sol-web had some issues.
Then I took latest of 5.2.x branch, which again broke solr-web. I fixed manually most of them.
Then I found issues with roleIds, with the help of the forum and source of 6.x, I fixed most of them.
What is the issue you are facing ? I have been testing with the above setup and its been working.
I can share my code with you so we can get more feedback and post it back to the community.

[Carlos del Castillo, modificado hace 14 años.]

Just wondering if the solr-plugin will be released for 5.2.3 and if you have any timeframe.

Thanks!

[Oana Tudorascu, modificado hace 14 años.]

Hello!

You mentioned that you have managed to deploy the solr-plugin v. 5.2.0.1 successfully in Liferay 5.2.2. I am trying to do the same thing at the moment and I get the following error:

Do you know what the problem might be?

Thank you!

[Denis Signoretto, modificado hace 14 años.]

I got the same error and I'm still waiting an looking for a working solution. Did solved the problem?
Which version of Solr are you using?

Thanks,
D.

[Wilson Man, modificado hace 14 años.]

you can try getting the latest from SVN under plugins / web

[Denis Signoretto, modificado hace 14 años.]

Hi wilson I downloaded the current solr web sources from here
http://svn.liferay.com/repos/public/plugins/branches/5.2.x/webs/solr-web/
but at compile I get 3 errors:

com.liferay.portal.search.solr.SolrSearchEngineImpl is not abstract and does not override abstract method unregister(java.lang.String) in com.liferay.portal.kernel.search.SearchEngine

Only implementing these methods the compilation works, but I don't know if an empty impelmentation it's good.

public boolean isRegistered() {
return false;
}

public void register(String string) { }

public void unregister(String string) { }

Also in trunk these methods are missing.

Do you know wich version of Solr is currently supported by 5.2.x plugin?

Thansk,
Denis.

I'm replying to myself. liferay it's using solr 1.3 since 5.2 version (http://issues.liferay.com/browse/LPS-397). Actually I get solr-web working on Liferay 5.2.3 after downloading solr-web plugin, appliyng differences of http://issues.liferay.com/browse/LPS-2885 (as bruno wrote, and it correspond to 30120 svn version) recompilig and redeploying it.

At the moment users search it's borken due to the issue: http://issues.liferay.com/browse/LPS-3120

Bye!

I believe, atleast all the official plugins should have a version for current community version. That way it would be easy.
